PART I

Item 1. Business

GENERAL

        White Mountains Insurance Group, Ltd. (the "Company" or the "Registrant") was originally formed as a Delaware corporation in 1980. In October 1999, the Company completed a corporate reorganization that changed its domicile from Delaware to Bermuda. The Company's principal businesses are conducted through its subsidiaries and affiliates in the businesses of property and casualty insurance and reinsurance. Within this report, the consolidated organization is referred to as "White Mountains". The Company's headquarters are located at Bank of Butterfield Building, 42 Reid Street, Hamilton, Bermuda HM 12, its principal executive office is located at 80 South Main Street, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11. White Mountains' reportable segments are OneBeacon, White Mountains Re, Esurance and Other Operations.

        The OneBeacon segment consists of the OneBeacon Insurance Group LLC family of companies (collectively "OneBeacon"), which are U.S.-based property and casualty insurance writers, substantially all of which operate in a multi-company pool. OneBeacon offers a wide range of specialty, personal and commercial products and services sold primarily through select independent agents. OneBeacon was acquired by White Mountains from Aviva plc ("Aviva", formerly CGU) on June 1, 2001 (the "OneBeacon Acquisition").

        The White Mountains Re segment consists of White Mountains Re Group, Ltd. and its subsidiaries. White Mountains Re offers lead capacity for reinsurance on most liability, property and accident & health exposures through its reinsurance subsidiaries, Folksamerica Reinsurance Company (together with its parent, Folksamerica Holding Company, "Folksamerica", which has been a wholly-owned subsidiary of White Mountains since 1998) and Sirius International Insurance Corporation ("Sirius International"). On April 16, 2004, White Mountains acquired Sirius Insurance Holdings Sweden AB and its subsidiaries ("Sirius") from ABB Ltd. (the "Sirius Acquisition"). The principal companies acquired were Sirius International, Sirius America Insurance Company ("Sirius America"), which provides primary insurance programs in the United States, and Scandinavian Reinsurance Company Ltd. ("Scandinavian Re"), a reinsurance company that has been in run-off since 2002. White Mountains Re also provides reinsurance advisory services, specializing in international property and marine excess reinsurance, through White Mountains Underwriting Limited (domiciled in Ireland and formed in 2001) and White Mountains Underwriting (Bermuda) Limited, formed in 2003 (collectively, "WMU").

        The Esurance segment consists of Esurance Holdings, Inc. and its subsidiaries (collectively, "Esurance"). Esurance, which has been a unit of White Mountains since October 2000, markets personal auto insurance directly to customers and through select online agents.

        White Mountains' Other Operations segment consists of the Company and its intermediate holding companies, as well as the International American Group, Inc. (the "International American Group"). The International American Group, which was acquired by White Mountains in 1999, consists of American Centennial Insurance Company ("American Centennial") and British Insurance Company of Cayman ("British Insurance Company"), both of which are in run-off.

        On November 30, 2004, White Mountains completed a significant corporate reorganization. As part of the reorganization, ownership of Folksamerica was transferred to White Mountains Re from Fund American Companies, Inc. ("Fund American"), which remains OneBeacon's parent. As a result, the legal organization of White Mountains' subsidiaries is consistent with its main operating businesses (i.e., OneBeacon, White Mountains Re and Esurance), and White Mountains Re is now a cohesive,

3



global reinsurance organization. The reorganization also allows White Mountains to independently manage the financial structures of its main operating segments.


White Mountains' Operating Principles

        White Mountains strives to operate within the spirit of four operating principles. These are:

        Underwriting Comes First.    An insurance enterprise must respect the fundamentals of insurance. There must be a realistic expectation of underwriting profit on all business written, and demonstrated fulfillment of that expectation over time, with focused attention to the loss ratio and to all the professional insurance disciplines of pricing, underwriting and claims management.

        Maintain a Disciplined Balance Sheet.    The first concern here is that insurance liabilities must always be fully recognized. Loss reserves and expense reserves must be solid before any other aspect of the business can be solid. Pricing, marketing and underwriting all depend on informed judgment of ultimate loss costs and that can be managed effectively only with a disciplined balance sheet.

        Invest for Total Return.    Historical insurance accounting has tended to hide unrealized gains and losses in the investment portfolio and over reward reported investment income (interest and dividends). Regardless of the accounting, White Mountains must invest for the best growth in after-tax value over time. In addition to investing our bond portfolios for total after-tax return, that will also mean prudent investment in a balanced portfolio consistent with leverage and insurance risk considerations.

        Think Like Owners.    Thinking like owners has a value all its own. There are stakeholders in a business enterprise and doing good work requires more than this quarter's profit. But thinking like an owner embraces all that without losing the touchstone of a capitalist enterprise.


ONEBEACON

        On June 1, 2001, White Mountains purchased CGU Corporation from Aviva and renamed the company OneBeacon. Headquartered in Boston, Massachusetts, OneBeacon is one of the oldest property and casualty insurers in the United States, tracing its roots to 1831 and the Potomac Fire Insurance Company. OneBeacon's legacy includes being among the first to issue automobile policies, honoring claims arising from the great San Francisco earthquake and the sinking of the Titanic, as well as insuring several U.S. presidents.

        At December 31, 2004 and 2003, OneBeacon had $10.0 billion and $11.3 billion of total assets, respectively, and shareholder's equity of $2.3 billion and $2.2 billion, respectively. OneBeacon's principal operating insurance subsidiaries are rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best, a rating agency which specializes in the insurance and reinsurance industry.


Property and Casualty Insurance Overview

        Generally, property and casualty insurance companies write insurance policies in exchange for premiums paid by its customers (the insured). An insurance policy is a contract between the insurance company and the insured where the insurance company agrees to pay for losses suffered by the insured that are covered under the contract. Such contracts often are subject to subsequent legal interpretation by courts, legislative action and arbitration. Property insurance generally covers the financial consequences of accidental losses to the insured's property, such as a home and the personal property in it, or a business' building, inventory and equipment. Casualty insurance (often referred to as liability insurance) generally covers the financial consequences of a legal liability of an individual or an organization resulting from negligent acts and omissions causing bodily injury and/or property damage to a third party. Claims on property coverage generally are reported and settled in a relatively short period of time, whereas those on casualty coverage can take years, even decades, to settle.

        Insurance companies derive substantially all of their revenues from earned premiums, investment income and net gains and losses from sales of investment securities. Earned premiums represent premiums received from insureds, which are recognized as revenue over the period of time during which insurance coverage is provided (i.e., ratably over the life of the policy). A significant period of time normally elapses between the receipt of insurance premiums and the payment of insurance claims. During this time, investment income is generated, consisting primarily of interest earned on fixed maturity investments and dividends earned on equity securities. Net realized investment gains and losses result from sales of securities from the insurance companies' investment portfolios.

        Insurance companies incur a significant amount of their total expenses from policyholder losses, which are commonly referred to as "claims". In settling policyholder losses, various loss adjustment expenses ("LAE") are incurred, such as insurance adjusters' fees and litigation expenses. In addition, insurance companies incur policy acquisition expenses such as commissions paid to agents and premium taxes, and other expenses related to the underwriting process, including compensation and benefits for professional and clerical staff.

        The key measure of relative underwriting performance for an insurance company is the combined ratio. An insurance company's combined ratio under accounting principles generally accepted in the United States ("GAAP") is calculated by adding the ratio of incurred loss and LAE to earned premiums (the "loss ratio") and the ratio of commissions, premium taxes and other underwriting expenses to earned premiums (the "expense ratio"). A combined ratio under 100% indicates that an insurance company is generating an underwriting profit. However, when considering investment income and investment gains or losses, insurance companies operating at a combined ratio of greater than 100% can be profitable.


Lines of Business

        OneBeacon provides specialty lines insurance products and a variety of segmented personal lines insurance products (for individuals) and commercial lines insurance products (for businesses).

        OneBeacon has built specialty businesses by providing customized coverages to certain niche markets. These specialty businesses are not subject to extreme competitive market conditions and are distinct in their product design. Each specialty business has its own operations and distribution channels that target specific customer groups. OneBeacon's specialty lines insurance products include the following:

        OneBeacon's personal lines coverages include homeowners insurance, segmented private passenger automobile and package policies sold through select independent agents. In addition, OneBeacon provides management services for a fee to reciprocal exchanges. OneBeacon's focus on commercial lines is to write property, liability, automobile and other related lines for small and mid-sized businesses for specific industry segments. While its personal and commercial businesses are subject to more competitive pressures, OneBeacon believes that through proper segmentation in product design and rating, OneBeacon has created certain specialty niches in these segments. OneBeacon's objective is to underwrite only profitable business without regard to market share or premium growth. OneBeacon's personal and commercial lines insurance products include the following:

Other lines of business for 2004 are primarily from premiums written by reciprocal insurance exchanges administered by OneBeacon, while Other lines of business for 2003 and 2002 are primarily from business assumed from Liberty Mutual Insurance Group ("Liberty Mutual").

        OneBeacon's specialty businesses include a LAD service provider (AutoOne Insurance), rural and farm related products (offered through National Farmers Union Property and Casualty Company, "NFU"), ocean marine (offered through International Marine Underwriters, "IMU"), medical errors and omissions (offered through OneBeacon Professional Partners, "OBPP"), agricultural ("Agri"), and other specialty products, such as tuition reimbursement. Additionally, in 2004, OneBeacon entered into the excess and surplus lines property business with the introduction of OneBeacon Specialty Property ("OBSP"). For the twelve months ended December 31, 2004, 2003 and 2002, OneBeacon's specialty lines net written premiums were as follows:

        As a condition to its license to write automobile business within New York, an insurance carrier is obligated by statute to accept future assignments from the NYAIP, a residual insurance market that obtains personal automobile insurance for those individuals who cannot otherwise obtain it in the voluntary insurance market. Alternatively, an insurance carrier can contractually satisfy its NYAIP obligation by (1) transferring its NYAIP assignments to another insurance company, or (2) through utilization of various credits offered by New York to those insurers who voluntarily write policies for individuals in the NYAIP. The process of transferring NYAIP obligations is called Limited Assigned Distribution, and the companies that assume this obligation are called LAD servicing carriers. New Jersey and certain other states have similar programs for personal and commercial automobile.

        In 2001, OneBeacon created AutoOne Insurance to provide LAD services and takeout credits to insurance companies required to accept future assignments from the NYAIP. In January 2004, AutoOne

7



Insurance also began to handle NJ PAIP business as a LAD servicing carrier. New Jersey is now the second largest market in the United States for LAD servicing carriers, with nearly $300 million in NJ PAIP written premium over the last 12 months. Combined, the New York and New Jersey markets account for nearly 85 percent of personal automobile written premium serviced in the country through LAD servicing carriers. Additionally, AutoOne Insurance expects to begin writing LAD and commercial LAD business in several new states in 2005, including Pennsylvania, Texas, California, Connecticut, Vermont, Maine and Delaware.

        In late 2004, AutoOne Insurance introduced a multi-tiered private passenger auto product in New York. This sophisticated product utilizes underwriting tiers to move the price point higher or lower based on risk characteristics. The tiered structure is a key element in the design, as it provides the flexibility needed to adjust to changing market and competitor conditions.

        During 2004, OneBeacon entered the excess and surplus lines property business through its new OBSP division, which is focused on providing solutions for the excess property market. This new business is developing a portfolio with attachment points and policy limits tailored to specific business-class and market conditions. Target classes include schools and universities, municipalities, habitational risks (apartment/condos.), real estate and related classes (offices buildings, shopping centers), retail, wholesale (warehousing), builders risks and other inland marine classes.

        Since 2001, OneBeacon has expanded its specialty businesses to seven companies which represent 35% of OneBeacon's total net written premiums in 2004.

        OneBeacon's personal lines principally include automobile, homeowners and Custom-Pac products (Custom-Pac products are combination policies offering home and automobile coverage with optional umbrella, boatowners and other coverages). OneBeacon's mix of personal lines products between automobile and homeowners, including Custom-Pac products, was 67% and 25%, respectively, of personal lines net written premium during 2004, compared to 63% and 30%, respectively, during 2003 and 69% and 24%, respectively, during 2002. OneBeacon writes the majority of its personal business in New York, Massachusetts and Maine.

        During 2004, OneBeacon launched a new multi-tiered product, OneChoice, in the Northeast. OneChoice enables OneBeacon to offer a broader range of coverages by allowing it to develop more sophisticated pricing models that have a greater statistical correlation between historical loss experience and price than traditional pricing models have shown. OneBeacon believes this product will enable it to profitably expand in selected markets throughout the United States.

        OneBeacon's commercial lines products principally include multi-peril, commercial automobile and workers compensation, which represented 54%, 23% and 14%, respectively, of commercial lines net written premium during 2004, compared to 55%, 23% and 8%, respectively, during 2003 and 52%, 29% and 14%, respectively, during 2002.

        On March 31, 2004, OneBeacon acquired Atlantic Specialty Insurance Company ("Atlantic Specialty"), a subsidiary of Atlantic Mutual Insurance Company ("Atlantic Mutual"), and the renewal rights to Atlantic Mutual's segmented commercial insurance business, including the unearned premiums on the acquired book (the "Atlantic Specialty Transaction"). The overall gross written premium for this book of business totals approximately $400 million. This transaction has allowed OneBeacon to sell a highly segmented product to small and mid-sized companies on an industry basis. These industries include but are not limited to technology, professional services, printers and wholesalers.

        During the third quarter of 2004, OneBeacon entered into an agreement to sell the renewal rights to most of its pre-Atlantic Mutual New York commercial business to Tower Insurance Group. The transaction, effective with December 1, 2004 renewals, will impact approximately $110 million of premiums. OneBeacon will retain the commercial business acquired from Atlantic Mutual.

        OneBeacon's other lines include the results of reciprocal insurance exchanges that are included in OneBeacon's GAAP results and also business assumed from Liberty Mutual.

        Reciprocal insurance exchanges are policyholder-owned insurance associations. As part of a restructuring of its New Jersey personal lines, in 2002, OneBeacon formed New Jersey Skylands Management LLC to provide management services for a fee to the New Jersey Skylands Insurance Association, a reciprocal exchange, and its wholly owned subsidiary New Jersey Skylands Insurance Company (together, the "Association"). The Association began writing personal automobile coverage for new customers in August 2002. Additionally, during 2004, OneBeacon formed Houston General Management Company to provide management services for a fee to another reciprocal exchange, Houston General Insurance Exchange (the "Exchange"). OneBeacon has no ownership interest in the Association or the Exchange. As a result of accounting literature changes, OneBeacon began consolidating the results of reciprocal insurance exchanges on March 31, 2004 (See Note 15—Variable Interest Entities in the accompanying Consolidated Financial Statements). Net written premiums written by the Association and the Exchange that were included in OneBeacon's 2004 results totaled $75.0 million.

        On November 1, 2001, OneBeacon transferred its regional agency business, agents and operations in 42 states and the District of Columbia to Liberty Mutual pursuant to a renewal rights agreement (the "Liberty Agreement"). This transfer amounted to approximately 45% of OneBeacon's total business at the time of transfer. The Liberty Agreement expired on October 31, 2003. As a result, OneBeacon earned premium in 2004 on policies written prior to the expiration, but did not write any new premiums in 2004 under the Liberty Agreement. Net written premiums assumed under the Liberty Agreement were $130.4 million in 2003 and $496.7 million in 2002.


Geographic Concentration

        OneBeacon's net written premiums are derived solely from business produced in the United States. Business from specialty, personal and commercial lines was produced in the following states:

Marketing

        OneBeacon offers its products though a combination of independent agents, regional and national brokers, wholesalers and captive agents (through NFU). In total, OneBeacon has approximately 2,000 agency and distribution relationships.

        OneBeacon's specialty businesses are located in separate locations, logistically appropriate to their target markets. AutoOne Insurance issues its LAD business through independent agents, generating takeout credits (in New York only) through this business to sell to other insurance carriers subject to NYAIP assignments. IMU distributes its products through a network of select agents that specialize in the ocean marine business. Agri distributes its products through independent agencies. NFU distributes its products primarily through a network of exclusive agents. Substantially all of these exclusive agents are under contract with NFU and the National Farmers Union, a non-profit organization founded in 1902 to advance the interests of family farmers. OBPP distributes its products nationally through excess and surplus lines brokers. OBSP's excess property solutions are provided primarily through surplus lines wholesalers. Through these distribution channels, OneBeacon leverages its knowledge about specialty markets to provide products and services that are tailored to meet customer needs.

        OneBeacon distributes its personal and commercial lines products through select independent insurance agents. OneBeacon believes that independent agents provide complete assessments of their clients' needs, which results in appropriate coverages and prudent risk management. OneBeacon believes that independent agents will continue to be a significant force in overall industry premium production.


Underwriting and Pricing

        OneBeacon believes that there must be a realistic expectation of attaining an underwriting profit on all the business it writes as well as a demonstrated fulfillment of that expectation over time. Adequate pricing is a critical component to the achievement of an underwriting profit and requires a disciplined approach towards pricing insurance products. Inadequate pricing can be caused by pressures from: (1) insurance companies selling their products at rates less than those acceptable to OneBeacon because they either underestimate ultimate claim costs or overestimate the amount of investment income and investment gains they will earn on premiums collected before claims are paid, (2) insurance companies willing to accept a lower return on investment for their stakeholders than OneBeacon, (3) insurance companies seeking to increase revenues and market share by reducing the price of their products beneath levels acceptable to OneBeacon, (4) the emergence and continued growth of insurance company competitors that have lower cost structures, and (5) state regulation, legislation and judicial mandates.

        Beginning in 2003 and continuing through 2004, OneBeacon introduced tiered rating plans in both its personal and commercial lines which permit OneBeacon to offer more price points to its customers based on underwriting criteria applicable to each tier. As a result, OneBeacon now has the flexibility to renew expiring policies into the appropriate tier rather than being forced to choose to either renew the policy at the same base rate or cancel the policy. Management believes that this significant improvement in the accuracy and precision of OneBeacon's rate plans moves it toward the pricing sophistication of the best insurance underwriters in the market.

        These tiers are just one example of OneBeacon's segmented underwriting and pricing strategy. Segmentation is a key driver of OneBeacon's success in specialty lines and is being carried over into personal and commercial lines. OneBeacon develops proprietary knowledge about a given industry/class/risk type which provides it with a competitive edge when offering terms and conditions on individual accounts. OneBeacon believes this will deliver superior returns versus a more "generalist" underwriting approach.

10



        OneBeacon also monitors pricing activity on a weekly basis and regularly measures usage of tiers, credits, debits and limits; this includes monthly review calls with all field offices. In addition, it regularly updates base rates to achieve targeted returns on surplus and attempts to shift writings away from price inadequate lines/classes. Lastly, OneBeacon expends considerable effort to measure and verify exposure bases and values.


Competition

        Property and casualty insurance is highly competitive and extensively regulated by state insurance departments. In specialty lines, OneBeacon competes with numerous regional and national insurance companies, most notably The Robert Plan Corporation, The Chubb Corporation, American International Group, The St. Paul Travelers Companies and the regional Farm Bureaus. In personal and commercial lines, OneBeacon competes with numerous regional and national insurance companies, most notably The St. Paul Travelers Companies, Zurich Insurance Group, CNA Financial, the Hartford Financial Services Group, Allmerica Financial Corporation, W.R. Berkley Corporation, The Chubb Corporation, Progressive Insurance, Allstate Insurance and Liberty Mutual. The more significant competitive factors for most insurance products offered by OneBeacon are price, product terms and claims service, which OneBeacon believes is the most important product differentiation that it brings to its agents and insureds. OneBeacon's underwriting principles and dedication to agency distribution are unlikely to make them the low-cost provider in most markets. However, while it is often difficult for insurance companies to differentiate their products to consumers, OneBeacon believes that its dedication to providing superior product offerings, claims service, and localized underwriting experience gives it a competitive advantage over typical low-cost providers.


Claims Management

        Effective claims management is a critical factor in achieving satisfactory underwriting results. OneBeacon maintains an experienced staff of appraisers, medical specialists, managers, attorneys and field adjusters strategically located throughout its operating territories. OneBeacon also maintains a special investigative unit designed to detect insurance fraud and abuse, and support efforts by regulatory bodies and trade associations to curtail the cost of fraud.

        OneBeacon's claims department's commitment to improvement is producing positive results. In 2004, OneBeacon made several operational changes in the claims department. Claims are now separately organized by specialty and commercial lines, personal lines and run-off operations. This segmentation has allowed OneBeacon to increase loss cost management specialization and better identify claims handling costs. OneBeacon introduced a total claims cost management practice which gives equal importance to controlling claims handling costs, legal expenses and claims payments, enabling OneBeacon to lower its overall claims handling costs. At the same time, over 97% of OneBeacon's insureds that responded to surveys were satisfied by the service provided by OneBeacon.

        OneBeacon's claims department utilizes a modern claims workstation, implemented in 2002, that in addition to recording reserves, payments and adjuster activity, assists each claims handler in evaluating bodily injury claims, determining liability and identifying fraud. OneBeacon's commitment and performance in fighting insurance fraud not only reduces claim costs but has aided law enforcement. Under OneBeacon's Staff Counsel Program, in-house attorneys defended 55% of its newly arising suits at a cost of $8.0 million less than it would have cost to use outside counsel. OneBeacon's internal legal bill audit team saved an additional $6.2 million by reducing legal invoices submitted by outside counsel.

        Calender year reported claims in OneBeacon's ongoing businesses were down 19% in 2004 compared to 2003. This allowed the claims department personnel to increase their focus on older open claims. At December 31, 2004, total open claims were down 22% from December 31, 2003.

        Calendar year reported claims in OneBeacon's operations in run-off were 5,900 in 2004 compared to 10,300 in 2003. Total open claims in run-off at December 31, 2004 were 14,600 compared to 28,500 at December 31, 2003, a 49% reduction. This number includes all of the claims that were previously handled by Liberty Mutual as a Third Party Administrator ("TPA"). The majority of OneBeacon's claims are handled by in-house adjusters with the exception of certain claims of certain businesses in run-off. Additionally, National Indemnity Company ("NICO") is used as a TPA for asbestos and environmental reinsurance claims relating to the NICO Cover (see "Asbestos and Environmental Reserves" discussion included in CRITICAL ACCOUNTING ESTIMATES in Management's Discussion and Analysis of Financial Condition and Results of Operations below). OneBeacon claims department personnel are consulted by NICO on major claims. As with all TPAs, claims department personnel perform claim audits on NICO to ensure their controls, processes and settlements are appropriate.

        During the year, OneBeacon identified additional areas in claims processing which will be continuously improved in 2005, including litigation management, expense management and staff productivity.


Terrorism

        Since the terrorist attacks of September 11, 2001 (the "Attacks"), OneBeacon has sought to mitigate the risk associated with any future terrorist attacks by reducing the insured value of policies written in geographic areas with a high concentration of exposure to losses from terrorist attacks or by seeking to exclude coverage for such losses from their policies.

        On November 26, 2002, President Bush signed the Terrorism Risk Insurance Act (the "Terrorism Act") establishing a federal "backstop" for commercial property and casualty losses, including workers compensation, resulting from acts of terrorism by or on behalf of any foreign person or foreign interest. The Terrorism Act requires primary commercial insurers to make terrorism coverage available immediately and provides Federal protection above individual company retention and aggregate industry retention levels. OneBeacon estimates its individual retention level for commercial policies subject to the Terrorism Act to be approximately $160.0 million in 2005. Aggregate industry retention levels are $15.0 billion for 2005. The Federal government will pay 90% of covered terrorism losses that exceed either OneBeacon's or the industry's retention levels up to $100.0 billion. The fate of the Terrorism Act beyond 2005 remains uncertain. It is anticipated that Congress will likely rule on a possible extension during the summer of 2005; however, there is a chance that the Terrorism Act could expire on December 31, 2005. To prepare for that possibility, OneBeacon is notifying customers (in states where permitted) with policies that expire in 2006 of the potential implications to their coverage. OneBeacon's current property and casualty catastrophe reinsurance programs provide coverage for "non-certified" events as defined under the Terrorism Act, provided such losses are not the result of a nuclear, biological or chemical attack. See the discussion in the "Reinsurance Protection" section below for a further description of OneBeacon's catastrophe program.

        OneBeacon closely monitors and manages its concentration of risk by geographic area. Beginning in 2002 and continuing through 2004, OneBeacon aggressively reduced its terrorism exposure in the largest metropolitan areas in which OneBeacon writes insurance by implementing a strategy that limits total probable maximum loss ("PML") from a terrorism event in any half mile radius. (PML is a statistical modeling technique that measures a company's catastrophic exposure as the maximum probable loss in a given time period.) The addition of the Atlantic Mutual book in 2004 resulted in some areas exceeding corporate PML thresholds. In these areas, specific account exposure reduction plans have been established to bring exposures within tolerance levels by the end of 2005. The financial exposure of potential new business is evaluated when it is located in an area of existing concentration or individually presents significant terrorism exposure. Additionally, formal reports are generated quarterly to validate that action adheres to corporate standards. As a result, OneBeacon believes that it has taken appropriate actions to mitigate its exposure to losses from future terrorist attacks and will

12



continue to monitor its terrorism exposure in the future. Nonetheless, risks insured by OneBeacon, and those contemplated by the enacted Terrorism Act, remain exposed to future terrorist attacks and the possibility remains that any future terrorist losses could prove to be material to the Company's financial position and/or its cash flows.


Reinsurance Protection

        In the ordinary course of its business, OneBeacon purchases reinsurance from high-quality, highly rated third party reinsurers in order to provide diversification of its business and minimize loss from large risks or catastrophic events. OneBeacon uses PML forecasting to quantify its exposure to catastrophic losses.

        The timing and size of catastrophe losses are unpredictable and the level of losses experienced in any year could be material to OneBeacon's operating results and financial position. Examples of catastrophes include losses caused by earthquakes, wildfires, hurricanes and other types of storms and terrorist acts. The extent of losses caused by catastrophes is both a function of the amount and type of insured exposure in an area affected by the event and the severity of the event. OneBeacon continually assesses and implements programs to manage its exposure to catastrophe losses through individual risk selection and by limiting its concentration of insurance written in catastrophe-prone areas, such as coastal regions. In addition, OneBeacon imposes wind deductibles on existing coastal windstorm exposures. OneBeacon's largest single natural catastrophe risk is Northeast windstorm.

        OneBeacon seeks to further reduce its exposure to catastrophe losses through the purchase of catastrophe reinsurance. Effective July 1, 2004, OneBeacon renewed its normal property catastrophe reinsurance program to cover its full estimated PML (one-in-250 year) through June 30, 2005. Under that cover, the first $200.0 million of losses resulting from any single catastrophe are retained by OneBeacon and losses from a single event in excess of $200.0 million and up to $850.0 million are reinsured for 100% of the loss. In the event of a catastrophe, OneBeacon can reinstate its property catastrophe reinsurance program for the remainder of the original contract term by paying a reinstatement premium which is based on the percentage of coverage reinstated and the original property catastrophe coverage premium.

        OneBeacon's property catastrophe reinsurance program does not cover personal or commercial property losses resulting from nuclear, biological or chemical terrorist attacks. The program covers personal property losses resulting from other types of terrorist attacks, and commercial property losses resulting from other types of domestic terrorist attacks or events not "certified" as defined under the Terrorism Act. The Terrorism Act provides protection for commercial property losses for certified events including those arising from nuclear, biological, or chemical attacks.

        OneBeacon also purchases individual property reinsurance coverage for certain risks to reduce large loss volatility. The Property per Risk reinsurance program reinsures losses in excess of $5.0 million up to $75.0 million. Individual risk facultative reinsurance may be purchased above $75.0 million where OneBeacon deems it appropriate. The Property per Risk treaty also reinsures losses in excess of $10.0 million up to $75.0 million on an individual risk basis for terrorism losses. However nuclear, biological, and chemical events are not covered.

        OneBeacon also maintains a casualty reinsurance program which provides protection for catastrophe losses involving workers compensation, general liability or automobile liability in excess of $5.0 million up to $60.0 million. This program provides one full $55.0 million limit for either "certified" or "non-certified" terrorism losses but does not provide coverage for losses resulting from nuclear, biological or chemical attacks.

        In connection with the OneBeacon Acquisition, Aviva caused OneBeacon to purchase reinsurance contracts with two reinsurance companies rated "AAA" (Extremely Strong) by Standard & Poor's and

13


"A++" (Superior) by A.M. Best: a full risk-transfer cover from NICO for up to $2.5 billion in old asbestos and environmental claims (the "NICO Cover") and an adverse development cover from General Reinsurance Corporation ("GRC") for up to $400.0 million on additional losses occurring in accident years 2000 and prior (the "GRC Cover").

        Reinsurance contracts do not relieve OneBeacon of its obligation to its ceding companies. Therefore, collectibility of balances due from its reinsurers is critical to OneBeacon's financial strength. See Note 4, "Third Party Reinsurance" in the accompanying Consolidated Financial Statements for a discussion of OneBeacon's top reinsurers.


Loss and Loss Adjustment Expense Reserves

        OneBeacon establishes loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain. See "CRITICAL ACCOUNTING ESTIMATES" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a full discussion regarding OneBeacon's loss reserving process.

        The following information presents (1) OneBeacon's reserve development over the preceding ten years and (2) a reconciliation of reserves in accordance with accounting principles and practices prescribed or permitted by insurance authorities ("Statutory" basis) to such reserves determined in accordance with GAAP, each as prescribed by Securities Act Industry Guide No. 6.

        Section I of the ten year table shows the estimated liability that was recorded at the end of each of the indicated years for all current and prior accident year unpaid losses and LAE. The liability represents the estimated amount of losses and LAE for claims that were unpaid at the balance sheet date, including incurred but not reported ("IBNR") reserves. In accordance with GAAP, the liability for unpaid losses and LAE is recorded in the balance sheet gross of the effects of reinsurance with an estimate of reinsurance recoverables arising from reinsurance contracts reported separately as an asset. The net balance represents the estimated amount of unpaid losses and LAE outstanding as of the balance sheet date, reduced by estimates of amounts recoverable under reinsurance contracts.

        Section II shows the re-estimated amount of the previously recorded net liability as of the end of each succeeding year. Estimates of the liability for unpaid losses and LAE are increased or decreased as payments are made and more information regarding individual claims and trends, such as overall frequency and severity patterns, becomes known. Section III shows the cumulative net (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2004. Section IV shows the re-estimated gross liability and re-estimated reinsurance recoverables through December 31, 2004. Section V shows the cumulative

amount of net losses and LAE paid relating to recorded liabilities as of the end of each succeeding year.

        The cumulative net (deficiency)/redundancy in the table above reflects reinsurance recoverables recorded in connection with the OneBeacon Acquisition under the NICO Cover and the GRC Cover. See Note 4, "Third Party Reinsurance" in the accompanying Consolidated Financial Statements for a description of the NICO Cover and the GRC Cover. These covers apply to losses incurred in 2000 and prior years. As a result, they have the effect of significantly increasing OneBeacon's reinsurance recoverables in 2001 and 2002 and reducing its reserve deficiency for each of the years presented prior to the OneBeacon Acquisition by the amount of the reserves ceded at the time these covers were purchased. See "Asbestos and Environmental Reserves" under "CRITICAL ACCOUNTING ESTIMATES" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a discussion of the impact of the NICO Cover on OneBeacon's net loss and LAE reserve position. The table presented below represents OneBeacon's cumulative net deficiency without regard to the NICO Cover and the GRC Cover.

WHITE MOUNTAINS RE

        During 2004, White Mountains formed White Mountains Re, which combined Folksamerica, Fund American Reinsurance Company, Ltd. ("Fund American Re") and WMU with the newly acquired Sirius to form a cohesive, global reinsurance organization.

        White Mountains Re offers lead capacity for reinsurance on most property, accident & health and liability exposures and writes direct program insurance business through Sirius America. White Mountains Re also provides reinsurance advisory services through WMU, specializing in international property and marine excess reinsurance. White Mountains Re has offices in Belgium, Bermuda, Chicago, Connecticut, Dublin, Hamburg, London, Miami, New York, Singapore, Stockholm, Toronto and Zurich. At December 31, 2004 and 2003, White Mountains Re had $8.2 billion and $3.7 billion of total assets and $1.7 billion and $1.0 billion of shareholder's equity, respectively.

16


        Folksamerica, which became a wholly-owned subsidiary of White Mountains in 1998, is a multi-line property and casualty reinsurer that provides reinsurance to insurers primarily in the United States, Canada, Continental Europe, Latin America, the Caribbean and Japan. Folksamerica Re is rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best.

        On April 16, 2004, White Mountains completed the Sirius Acquisition, through which the principal operating companies acquired were Sirius International and Sirius America. Stockholm-based Sirius International is a multi-line property and casualty reinsurer that provides reinsurance primarily in Europe, North America and Asia and is the largest reinsurance company domiciled in Scandinavia (based on gross written premiums). Sirius America is a U.S.-based insurer that specializes in primary insurance programs. Sirius International and Sirius America are both rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best.

        Effective October 1, 2003, White Mountains Re acquired renewal rights to the property and casualty treaty reinsurance business of CNA Reinsurance ("CNA Re"), a division of CNA Financial Corporation (the "CNA Re Agreement"). Under the terms of the CNA Re Agreement, White Mountains Re pays CNA Re a renewal commission on the premiums renewed over the two contract renewal periods subsequent to October 1, 2003. The renewal commission is 3% for the initial renewal and 2% for the second renewal.

        In December 2001, White Mountains formed WMU, a reinsurance advisory company domiciled in Ireland. As part of a corporate reorganization, WMU established a sister company in Bermuda in June 2003. WMU provides reinsurance underwriting advice and reinsurance portfolio analysis services to both Folksamerica and Olympus Reinsurance Company Ltd. ("Olympus"). Prior to the Sirius Acquisition, WMU's Irish company, a specialist in handling non-marine property treaty excess of loss classes, expanded White Mountains Re's international profile, particularly in the United Kingdom, Continental Europe, Japan and Australia. WMU's Bermuda company specializes in excess reinsurance coverages for the marine and energy sector.

        Since 1999, in addition to the transactions discussed above, White Mountains Re has made the following acquisitions:

Reinsurance Overview

        Reinsurance is an arrangement in which a reinsurance company (the "reinsurer") agrees to indemnify an insurance company (the "ceding company") for all or a portion of the insurance risks underwritten by the ceding company under one or more insurance policies. Reinsurance can benefit a ceding company in a number of ways, including reducing exposure on individual risks, providing catastrophe protections from large or multiple losses, and assisting in maintaining acceptable capital levels as well as financial and operating leverage ratios. Reinsurance can also provide a ceding company with additional underwriting capacity by permitting it to accept larger risks and underwrite a greater number of risks without a corresponding increase in its capital or surplus. Reinsurers may also purchase reinsurance, known as retrocessional reinsurance, to cover their own risks assumed from primary ceding companies. Reinsurance companies often enter into retrocessional agreements for many of the same reasons that ceding companies enter into reinsurance agreements.

        Reinsurance is generally written on a treaty or facultative basis. Treaty reinsurance is an agreement whereby the reinsurer assumes a specified portion or category of risk under all qualifying policies issued by the ceding company during the term of the agreement, usually one year. In the underwriting of treaty reinsurance, the reinsurer does not evaluate each individual risk and generally accepts the original underwriting decisions made by the ceding insurer. Treaty reinsurance is typically written on either a quota share or excess of loss basis. A quota share reinsurance treaty is an arrangement whereby a reinsurer assumes a predetermined proportional share of the premiums and losses generated on specified business. An excess of loss treaty is an arrangement whereby a reinsurer assumes losses that exceed an agreed retention of loss by the ceding company. Facultative reinsurance, on the other hand, is underwritten on a risk-by-risk basis, which allows the reinsurer to determine pricing for each exposure.

        A significant period of time normally elapses between the receipt of reinsurance premiums and the payment of reinsurance claims. While premiums are generally paid to the reinsurer upon inception of coverage, the claims process is delayed and generally begins upon the occurrence of an event causing an insured loss followed by: (1) the reporting of the loss by the insured to the ceding company; (2) the reporting of the loss by the ceding company to the reinsurer; (3) the ceding company's adjustment and payment of the loss; and (4) the payment to the ceding company by the reinsurer. During this time, reinsurance companies generate investment income on premium receipts, consisting primarily of interest earned on fixed maturity investments and dividends earned on equity securities. The period of time between the receipt of premiums and the payment of claims is typically longer for a reinsurer than for a primary insurer.


Classes of Business

        White Mountains Re writes three main classes of reinsurance: liability, property and accident and health. White Mountains Re's net written premiums by class of business for the years ended December 31, 2004, 2003 and 2002 were as follows:

        White Mountains Re writes both treaty and facultative reinsurance, as well as direct business. The majority of White Mountains Re's premiums are derived from treaty reinsurance contracts both on a quota share and an excess of loss basis, which in 2004 amounted to 55% and 34%, respectively, of its total net written premiums, while direct business represented 11% of total net written premium.

        During the years ended December 31, 2004, 2003 and 2002, White Mountains Re received no more than 10% of its gross reinsurance premiums from any individual ceding company. During the years ended December 31, 2004, 2003 and 2002, White Mountains Re received approximately 51%, 58% and 57%, respectively, of its gross reinsurance written premiums from three major, third-party reinsurance brokers as follows: (1) AON Re—22%, 25% and 28%, respectively; (2) Benfield—16%, 19% and 14%, respectively; and (3) Guy Carpenter—13%, 14% and 15%, respectively.

Marketing

        White Mountains Re, which conducts its reinsurance business through Folksamerica and Sirius International, obtains most of its reinsurance business from reinsurance brokers. Business submissions come from intermediaries that represent the ceding company or through submissions recommended by WMU. White Mountains Re considers both the intermediary and the ceding company to be its clients in any placement. White Mountains Re has developed strong business relationships over a long period of time with the management of many of its ceding companies. The process of placing an intermediary reinsurance program typically begins when a ceding company enlists the aid of a reinsurance intermediary in structuring a reinsurance program. Often the ceding company and the broker will consult with one or more lead reinsurers as to the pricing and contract terms for the reinsurance protection being sought. Once the ceding company has approved the terms quoted by the lead reinsurer, the broker will offer participation to qualified reinsurers until the program is fully subscribed.

        White Mountains Re pays ceding companies a ceding commission under most quota share reinsurance treaties and some excess of loss reinsurance treaties. The ceding commission is generally based on the ceding company's cost of acquiring and administering the business being reinsured (commissions, premium taxes and certain miscellaneous expenses). Additionally, White Mountains Re pays reinsurance intermediaries commissions based on negotiated percentages of the premium they produce. The reinsurance intermediary's commissions constitute a significant portion of White Mountains Re's total acquisition costs.

        As mentioned above, White Mountains Re also writes direct program business through Sirius America, which began its program insurance operations in 1999. Sirius America works with managing general agents to produce U.S. based liability, property and accident & health insurance programs for small and mid-sized commercial accounts. Sirius America establishes strict underwriting guidelines,

19



closely monitors all exposures and performs periodic on-site audits of the managing general agents to confirm compliance with established guidelines and procedures.


Underwriting and Pricing

        White Mountains Re derives its business from a broad spectrum of ceding insurers including national, regional, specialty and excess and surplus lines writers, both in the United States and internationally. White Mountains Re determines which risks it accepts based on the anticipated underwriting results of the transaction, which are evaluated on a variety of factors including types of risk, the quality of the reinsured, the attractiveness of the reinsured's insurance rates and policy conditions and the adequacy of the proposed reinsurance terms.

        White Mountains Re's underwriters and pricing actuaries perform reviews of the underwriting, pricing, and general underwriting controls of potential clients before quoting contract terms for its reinsurance products. White Mountains Re prices its products by assessing the desired return on the expected capital needed to write a given contract and by estimating future loss and LAE costs. White Mountains Re accepts contracts that are anticipated to generate expected returns on capital and an underwriting profit. White Mountains Re's pricing indications are based on a number of underwriting factors including historical results, analysis of exposure and estimates of future loss costs, a review of other programs displaying similar exposure characteristics, the primary insurer's underwriting and claims experience and the primary insurer's financial condition. Folksamerica's underwriters and claims personnel perform regular audits on certain classes of business to monitor the ceding company's pricing and claim handling discipline. Sirius International's underwriters frequently communicate with ceding companies to discuss current terms and conditions. Additionally, White Mountains Re's finance staff reviews the financial stability and creditworthiness of certain ceding companies. Such reviews provide important input to support underwriting decisions.

        White Mountains Re and other reinsurance companies have sought to mitigate the risk associated with future terrorist attacks in a similar manner as primary insurers. Since the Attacks, reinsurers have attained significant price increases across all lines of reinsurance in response to greater perceived policy exposures. Reinsurers do not have the stringent regulations with respect to contract terms and policy exclusions which are generally imposed on primary writers. For example, the Terrorism Act is not applicable to reinsurers. As a result, exclusions are more often dictated by the marketplace than by regulation. White Mountains Re evaluates terrorism exposure to its ceding company clients and applies exclusions as appropriate. For example, reinsurance written on commercial risks subsequent to the Attacks generally contain clauses that exclude certified acts of terrorism. Reinsurance on personal risks written subsequent to the Attacks generally contain exclusions related to nuclear, biological and chemical attacks.


Claims Management

        White Mountains Re maintains a staff of experienced reinsurance claim specialists that work closely with reinsurance intermediaries to obtain specific claims information from its customers. Folksamerica's claims staff also regularly perform on site claim reviews to assess and suggest improvements regarding the reinsured's claim handling ability and reserving techniques. In addition, all of White Mountains Re's claims specialists review loss information provided by the reinsured for adequacy. The results of these claim reviews are shared with the actuaries and underwriters to ensure that they are making the correct assumptions in pricing products and that all relevant information is used in establishing loss reserves.

        White Mountains Re also uses TPAs for certain other claims, including the direct program business written by Sirius America and run-off claims related to the Sierra and PCA acquisitions. White

Competition

        In general, White Mountains Re competes for reinsurance business with other major global reinsurers, local reinsurers in certain markets and reinsurance divisions of direct insurance companies. Competition in the worldwide reinsurance market is influenced by a variety of factors, including financial strength ratings, prior history and relationships, as well as expertise and the speed at which the company has historically paid claims.

        Through Folksamerica, White Mountains Re competes with all of the larger U.S. reinsurance companies. As reported by the Reinsurance Association of America ("RAA") for the nine month period ending September 30, 2004, (the most recent data available), Folksamerica wrote approximately 6% of gross written premiums of all reinsurance companies that are viewed as direct competition. The reinsurance companies writing the largest portion of gross premiums in this period were: XL Reinsurance America (18%), Transatlantic Reinsurance Company (16%) and Everest Reinsurance Company (15%).

        Through Sirius International, the largest reinsurance company domiciled in Scandinavia (based upon gross written premiums), White Mountains Re competes with many of the larger European and international reinsurance companies, including Munich Re, Swiss Re, Hannover Re, Lloyds, Partner Re and Everest Re.

        White Mountains Re, through its operating subsidiaries, has a long history of close relationships with ceding companies and maintains a disciplined underwriting strategy which, among other things, focuses on writing more business when market terms and conditions are favorable and reducing business volume during soft markets when terms and conditions become less favorable. White Mountains Re also employs a multi-line approach, offering clients a wide range of reinsurance products to satisfy their risk management needs. Additionally, White Mountains Re's acquisition strategy has contributed to its growth. Since 1995, White Mountains Re has completed ten acquisitions of other insurance and reinsurance organizations. In virtually all cases the acquired entities were fundamentally sound, but were owned by organizations that no longer considered them core businesses.


Reinsurance Protection

        White Mountains Re has exposure to losses caused by hurricanes, earthquakes, winter storms, windstorms, terrorist acts and other catastrophic events. In the normal course of business, White Mountains Re seeks to reduce the risk of loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with other insurance and reinsurance enterprises and by closely monitoring aggregate property exposures and related PMLs. To manage and analyze aggregate exposures and PML, White Mountains Re utilizes a variety of tools and analyses, including catastrophe modeling software packages. White Mountains Re regularly assesses its concentration of underwriting exposures in catastrophe prone areas and develops strategies to manage this exposure, primarily through limiting accumulation of exposure to acceptable levels and, if deemed necessary, the purchase of catastrophe reinsurance.

        Folksamerica's primary reinsurance protection is through quota share arrangements with Olympus. These arrangements are designed to increase Folksamerica's capacity to capitalize on the improved pricing trends that accelerated after the Attacks and to reduce its potential loss exposure to any large, or series of smaller, property catastrophe events. Under its quota share agreements with Olympus, Folksamerica cedes up to 75% of substantially all of its short-tailed excess of loss business, mainly property and marine, and 50% of its proportional property business to Olympus and receives an override commission on the premiums ceded to Olympus.

21



        Under its prior ownership, Sirius' threshold for risk exposure and earnings volatility was extremely low. As a consequence, Sirius purchased many reinsurance protections at significant costs. These protections were purchased primarily to reduce the company's property catastrophe exposure on both a treaty and facultative basis. Under White Mountains Re's ownership, Sirius' reinsurance purchasing is coordinated with that of Folksamerica on a group-wide basis. Selective purchases are made primarily for property catastrophe protection. Effective April 1, 2004, Sirius International entered into a quota share reinsurance agreement with Olympus. Under this agreement, Sirius International cedes 25% of its short-tailed proportional and excess of loss business to Olympus. White Mountains Re receives an override commission on the premiums ceded to Olympus.

        Reinsurance contracts do not relieve White Mountains Re of its obligation to its ceding companies. Therefore, collectibility of balances due from its retrocessional reinsurers is critical to White Mountains Re's financial strength. See Note 4—"Third Party Reinsurance" to the accompanying Consolidated Financial Statements for a discussion of White Mountains Re's top reinsurers.


Loss and Loss Adjustment Expense Reserves

        White Mountains Re establishes reserves that are estimates of future amounts needed to pay claims and related expenses for insured events that have already occurred. See "CRITICAL ACCOUNTING ESTIMATES" in "Management's Discussion and Analysis of Financial Condition and Results of Operations" for a full discussion regarding White Mountains Re's loss reserving process.

        The following information presents (1) White Mountains Re's reserve development over the preceding ten years and (2) a reconciliation of reserves on a regulatory basis to reserves determined in accordance with GAAP, each as prescribed by Securities Act Industry Guide No. 6.

        Section I of the ten year table shows the estimated liability that was recorded at the end of each of the indicated years for all current and prior accident year unpaid losses and LAE. The liability represents the estimated amount of losses and LAE for claims that were unpaid at the balance sheet date, including IBNR reserves. In accordance with GAAP, the liability for unpaid losses and LAE is recorded in the balance sheet gross of the effects of reinsurance with an estimate of reinsurance recoverables arising from reinsurance contracts reported separately as an asset. The net balance represents the estimated amount of unpaid losses and LAE outstanding as of the balance sheet date, reduced by estimates of amounts recoverable under reinsurance contracts.

        Section II shows the re-estimated amount of the previously recorded net liability as of the end of each succeeding year. Estimates of the liability for unpaid losses and LAE are increased or decreased as payments are made and more information regarding individual claims and trends, such as overall frequency and severity patterns, becomes known. Section III shows the cumulative net (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2004. Section IV shows the re-estimated gross liability and re-estimated reinsurance recoverables through December 31, 2004. Section V shows the cumulative amount of net losses and LAE paid relating to recorded liabilities as of the end of each succeeding year.

        The following table includes the complete loss development history for all periods presented for all companies acquired by White Mountains Re as if the companies had been combined from their inception.

ESURANCE

        The Esurance group of companies, which is headquartered in San Francisco, have been part of White Mountains since October 2000. Esurance markets personal auto insurance directly to customers and through select online agents. Most customer interaction with the company takes place through Esurance's website, www.esurance.com. Through the website, customers can get real-time quotes, compare quotes from other companies, purchase their policies, report claims and manage their accounts.

        Esurance's underwriting companies, Esurance Insurance Company and Esurance Property and Casualty Insurance Company, are both rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best. Additionally, the Esurance segment also includes insurance ceded by Esurance to its affiliate, Folksamerica.

Marketing

        Esurance distributes approximately 80% of its business directly to customers online and over the phone. For this business, Esurance does not pay agent commissions on either new or renewal policies. The remaining 20% of Esurance's business is distributed through large online agents. Esurance targets convenience-focused, technology savvy consumers who use the Internet for most of their financial services transactions.

        Esurance attracts its target customers through a continuously optimized mix of online and offline advertising. Esurance advertises on a wide variety of insurance, finance, and automotive sites, along with major portals (e.g., MSN and Yahoo!) and search advertisers, like Google. Esurance also advertises on television, radio and through direct mail.


Underwriting and Pricing

        With its web-enabled technology, Esurance collects and verifies detailed underwriting information in real-time while customers transact with the company online. This real-time access to customer information allows Esurance to continually develop and refine its highly segmented, tiered pricing models. Esurance believes that its tiered pricing models have a greater statistical correlation with historical loss experience than traditional pricing models have shown. As a result, Esurance can quote rates to customers that most closely correspond to the individual risk characteristics of the customer, enabling Esurance to focus on keeping insurance rates competitive without compromising the company's loss ratio targets.


Competition

        Esurance competes with national and regional personal automobile insurance companies, though Esurance's main competition is other direct writers like Progressive, GEICO, and 21st Century.

        Esurance leverages web-enabled technology, allowing it to capture data real-time and react to market shifts. With an array of customer information at its disposal, Esurance is continually able to refine pricing, enhance its auto product and optimize dollars spent on marketing. Technology also allows Esurance to provide high quality, 24/7 customer service and claims handling for a competitive price.

25



        Esurance's paperless business process allow the company to significantly reduce operating costs typically associated with policy processing, verification and endorsement activities. As a result, the company is able to achieve efficient, low-cost acquisition and operating expense structures.


Claims Management

        Esurance handles its claims through regional claim centers in California, Florida, Texas and New York. Esurance takes the initial notice of loss at the company's customer service center, which is available for customers 24 hours a day, 365 days a year. The loss reporting unit then assigns claims to the regional claim centers.

        Esurance's claims organization leverages technology to reduce cycle times. Rapid response to and resolution of claims creates a stronger relationship with customers, while also decreasing ancillary claims costs, such as rental car fees. Additionally, Esurance maintains a special investigative unit designed to detect insurance fraud, and actively supports efforts by regulatory bodies and trade associations to curtail the cost of insurance fraud.


Catastrophe Risk

        Esurance's sole line of business is personal automobile insurance that covers liabilities and physical damage arising from the operation of automobiles. The majority of Esurance's customers elect coverage for physical damage (85%), resulting in exposure to catastrophe losses at Esurance for hurricanes, hailstorms, earthquakes and other acts of nature. Generally, catastrophe costs are low for personal auto in relation to other lines of business, such as homeowners and commercial property. Additionally, Esurance's broad geographic distribution limits its concentration of risk and the potential for losses to accumulate from a single event. Esurance estimates that its PML for a single event is less than 1% of net written premium.


Loss and Loss Adjustment Expense Information

        The process of estimating reserves for Esurance is similar to the process described in "Loss and Loss Adjustment Expense Reserves" in the "ONEBEACON" discussion and, as of any given date, is inherently uncertain. As described previously, uncertainties in projecting estimates of ultimate loss and LAE are magnified by the time lag between when a claim actually occurs and when it is reported and settled, i.e., the "claim-tail." Esurance writes primarily "short-tail" personal automobile insurance policies, which reduces the uncertainty inherent in its loss and LAE reserves when compared to insurance companies that write "long-tail" policies, such as workers compensation.

        Management believes that Esurance's loss and LAE reserves as of December 31, 2004 are adequate; however, ultimate loss and LAE may deviate, perhaps materially, from the amounts currently reflected in the reserve balance. Adverse development, if any, would impact the Company's future results of operations.

        The following information presents (1) Esurance's reserve development over the four years since inception and (2) a reconciliation of reserves on a Statutory basis to reserves determined in accordance with GAAP, each as prescribed by Securities Act Industry Guide No. 6.

        Section I of the table shows the estimated liability that was recorded at the end of each of the indicated years for all current and prior accident year unpaid losses and LAE. The liability represents the estimated amount of losses and LAE for claims that were unpaid at the balance sheet date, including IBNR reserves. In accordance with GAAP, the liability for unpaid losses and LAE is recorded in the balance sheet gross of the effects of reinsurance with an estimate of reinsurance recoverables arising from reinsurance contracts reported separately as an asset. The net balance represents the

26



estimated amount of unpaid losses and LAE outstanding as of the balance sheet date, reduced by estimates of amounts recoverable under reinsurance contracts.

        Section II shows the re-estimated amount of the previously recorded net liability as of the end of each succeeding year. Estimates of the liability for unpaid losses and LAE are increased or decreased as payments are made and more information regarding individual claims and trends, such as overall frequency and severity patterns, becomes known. Section III shows the cumulative net (deficiency)/redundancy representing the aggregate change in the liability from original balance sheet dates and the re-estimated liability through December 31, 2004. Section IV shows the re-estimated gross liability and re-estimated reinsurance recoverables through December 31, 2004. Section V shows the cumulative amount of net losses and LAE paid relating to recorded liabilities as of the end of each succeeding year.

OTHER OPERATIONS

The Company and its Intermediate Holding Companies

        The Company's intermediate holding companies include Fund American and Fund American Enterprises Holdings, Inc. ("FAEH"), both U.S.-domiciled companies, as well as various intermediate holding companies domiciled in the United States, Barbados, Luxembourg, Sweden and Bermuda. White Mountains arranges the majority of its financing through the Company and these intermediate holding companies.

        In May 2003, Fund American issued $700 million face value of senior unsecured debt through a public offering, at an issue price of 99.7% (the "Senior Notes"). The net proceeds from the issuance of the Senior Notes were used to repay all of the term loans and a portion of the revolving loan (with the remainder repaid with cash on hand) under Fund American's previous bank facility.

        In September 2003, Fund American terminated its old revolving credit facility, which then consisted solely of an undrawn $175 million revolving credit line, and replaced it with a new $300 million revolving credit facility (the "Bank Facility"), under which both Fund American and the Company are permitted borrowers. In August 2004, Fund American restructured and re-syndicated the Bank Facility to increase the availability under the revolving credit facility to $400 million and to extend the maturity from September 2006 to August 2009. As of December 31, 2004, the Bank Facility was undrawn.

        As part of the financing for the OneBeacon Acquisition, Berkshire Hathaway, Inc. ("Berkshire") invested a total of $300 million in cash, of which (1) $225 million was for the purchase of preferred stock of Fund American (the "Berkshire Preferred Stock"), which has a $300 million redemption value; and (2) $75 million was for the purchase of warrants to acquire 1,724,200 Common Shares of the Company (the "Warrants"). The Berkshire Preferred Stock is entitled to a dividend of no less than 2.35% per quarter and is mandatorily redeemable on May 31, 2008. During 2004, Berkshire exercised its warrants for $294 million in cash.

        Also as part of the financing of the OneBeacon Acquisition, Zenith Insurance Company ("Zenith") purchased $20 million in cumulative non-voting preferred stock of FAEH (the "Zenith Preferred Stock"). The Zenith Preferred Stock is entitled to a dividend of no less than a 2.5% per quarter through June 30, 2007 and a dividend of no less than 3.5% per quarter thereafter. The Zenith Preferred Stock is mandatorily redeemable on May 31, 2011. At the Company's option, the Zenith Preferred Stock may be redeemed on June 30, 2007.

International American Group

        In October 1999, White Mountains acquired the group of companies included in the International American Group, which included American Centennial, British Insurance Company and Peninsula.

        Delaware-domiciled American Centennial and Cayman Island-domiciled British Insurance Company are property and casualty insurance and reinsurance companies in run-off. At December 31, 2004 and 2003, American Centennial had $61.3 million and $61.1 million of total assets and $21.0 million and $22.6 million of shareholder's equity, respectively. At December 31, 2004 and 2003, British Insurance Company had $33.4 million and $25.7 million of total assets and $4.5 million and $5.6 million of shareholder's equity, respectively.

        In January 2004, White Mountains sold Peninsula, which is a Maryland-domiciled property and casualty insurer, for $23.3 million. At December 31, 2003 Peninsula had $60.6 million of total assets and $21.7 million of shareholder's equity, respectively. For the years ended December 31, 2003 and 2002, Peninsula had $34.1 million and $29.5 million of net written premiums, respectively.


INVESTMENTS

        The investment portfolios of White Mountains' insurance and reinsurance operations consist primarily of fixed maturity investments but also consist, in part, of short-term investments, common equity securities and other investments (principally investments in limited partnership interests). White Mountains' management believes that prudent levels of investments in common equity securities and other investments within its investment portfolio are likely to enhance after-tax total returns without significantly increasing the risk profile of the portfolio when considered over long periods of time and balanced with leverage and insurance risk considerations. White Mountains seeks to maximize after-tax risk-adjusted returns over the long term.

        At December 31, 2004, approximately 99% of White Mountains' fixed maturity investments received an investment grade rating from Standard and Poor's ("S&P") or from Moody's Investor Services ("Moody's") if a given security is unrated by S&P. S&P and Moody's are two third party rating agencies that assess the credit quality of companies that have publicly issued debt. An investment grade rating, which is indicative of a strong credit profile of an issuer, is defined as "BBB-" (Adequate, the 10th highest of 24 ratings) or better by S&P and "Baa3" (Adequate, the 10th highest of 21 ratings) or better by Moody's. White Mountains expects to continue to invest primarily in high quality, fixed maturity investments. Nearly all the fixed maturity investments currently held by White Mountains are publicly traded, and as such are considered to be liquid.

        At December 31, 2004 White Mountains' consolidated investment portfolio consisted of $7,900.0 million (75%) of fixed maturity investments, $1,058.2 million (10%) of short-term investments, $1,043.9 million (10%) of common equity securities and $527.4 million (5%) of other investments. White Mountains' fixed maturity investments at December 31, 2004 consisted principally of corporate debt securities (49%), U.S. government and agency securities (30%), foreign government obligations (10%), mortgage-backed securities (9%) and preferred equity securities and municipal bonds (2%).

29


        White Mountains' investment philosophy is to invest all assets with a view towards maximizing its after-tax total return over extended periods of time. Under this approach, each dollar of after-tax investment income, realized and unrealized gains and losses is valued equally. White Mountains' overall fixed maturity investment strategy is to purchase securities that are attractively priced in relation to perceived credit risks. White Mountains generally manages the interest rate risk associated with holding fixed maturity investments by actively monitoring and maintaining the average duration of the portfolio with a view towards achieving an adequate after-tax total return without subjecting the portfolio to an unreasonable level of interest rate risk. At December 31, 2004, the duration of White Mountains' fixed maturity investments and short-term investments was approximately 3 years.

Montpelier Re Holdings Ltd. ("Montpelier")

        In December 2001, White Mountains, the Benfield Group plc and several other private investors established Montpelier and its wholly owned subsidiary Montpelier Reinsurance Ltd. ("Montpelier Re"). Montpelier Re is a Bermuda-domiciled insurance and reinsurance company that was formed with approximately $1.0 billion in capital to respond to the then favorable underwriting and pricing environment in the reinsurance industry. Montpelier Re has initially focused on property reinsurance business. Montpelier Re is rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best. On October 15, 2002, Montpelier successfully completed an initial public offering and its common shares are listed on the New York Stock Exchange. White Mountains initially invested $180 million in Montpelier in exchange for 10.8 million common shares and warrants to acquire 4.8 million additional common shares of Montpelier.

        During the first quarter of 2004, White Mountains sold 4.5 million common shares of Montpelier to third parties. As a result of this sale, as well as changes to the composition of the Board of Directors of both Montpelier and White Mountains, White Mountains changed the method of accounting for its remaining common share investment in Montpelier as of March 31, 2004 from an equity method investment in an unconsolidated affiliate to a common equity security classified as available for sale and carried at fair value. Also during the first quarter of 2004, White Mountains purchased additional warrants to acquire 2.4 million common shares of Montpelier from an existing warrant holder for $54.1 million in cash, thereby raising the total number of such warrants owned by White Mountains to 7.2 million. The Montpelier warrants have an exercise price of $16.67 per share (as adjusted for stock splits) and are exercisable until December 2011.


Investments in Unconsolidated Affiliates

Symetra Financial Corporation ("Symetra")

        On August 2, 2004, White Mountains, Berkshire and several other private investors capitalized Symetra in order to purchase the life and investment operations of Safeco Corporation for $1.35 billion. The acquired companies, which are now operating under the Symetra brand, focus mainly on group insurance, individual life insurance, structured settlements and retirement services. Symetra had an initial capitalization of approximately $1.4 billion, consisting of $1,065 million of common equity and $315 million of debt. White Mountains invested $194.7 million in Symetra in exchange for 2.0 million common shares of Symetra. In addition, White Mountains and Berkshire each received warrants to acquire an additional 1.1 million common shares of Symetra at $100 per share. White Mountains owns approximately 19% of the outstanding common shares of Symetra and approximately 24% of Symetra on a fully-converted basis including the warrants. Three White Mountains designees serve on Symetra's eight member board of directors.

        Symetra's total revenues and net income for the five months ended December 31, 2004 were $701.9 million and $54.3 million, respectively. Symetra's total assets and shareholders' equity as of December 31, 2004 were $22.1 billion and $1.4 billion, respectively. As of December 31, 2004, White

30



Mountains' total investment in Symetra was $248.4 million, excluding $56.6 million of equity in unrealized gains from Symetra's fixed maturity investments.

Main Street America Holdings, Inc. ("MSA")

        MSA is a subsidiary of National Grange Mutual Insurance Company ("NGM"), a New Hampshire-domiciled property and casualty insurance company, which insures risks located primarily in New York, Massachusetts, Connecticut, Pennsylvania, New Hampshire, Virginia and Florida. White Mountains owns 50% of the outstanding common stock of MSA and accounts for this investment using the equity method. White Mountains' investment in MSA was $161.6 million and $142.8 million at December 31, 2004 and December 31, 2003, respectively. MSA's net written premiums totaled $454.5 million, $427.6 million and $357.3 million and its net income (loss) was $29.6 million, $29.3 million and ($13.2) million in 2004, 2003 and 2002. MSA's total assets as of December 31, 2004 and 2003 were $978.1 million and $875.1 million and its shareholders' equity was $323.3 million and $290.4 million. The principal insurance operating subsidiaries of NGM and MSA are rated "A" (Excellent, the third highest of fifteen ratings) by A.M. Best.


REGULATION

United States

        White Mountains' U.S.-based insurance and reinsurance operating subsidiaries are subject to regulation and supervision in each of the states where they are domiciled and licensed to conduct business. Generally, regulatory authorities have broad supervisory and administrative powers over such matters as licenses, standards of solvency, premium rates, policy forms, investments, security deposits, methods of accounting, form and content of financial statements, reserves for unpaid loss and LAE, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders. White Mountains believes that it is in compliance with all applicable laws and regulations pertaining to its business that would have a material effect on its financial position in the event of non-compliance.

        Over the last several years most states have implemented laws that establish standards for current, as well as continued, state accreditation. In addition, the NAIC has adopted risk-based capital ("RBC") standards for property and casualty insurers as a means of monitoring certain aspects affecting the overall financial condition of insurance companies. The current RBC ratios of White Mountains' active insurance and reinsurance operating subsidiaries are satisfactory and such ratios are not expected to result in any adverse regulatory action. White Mountains is not aware of any current recommendations by regulatory authorities that would be expected to have a material effect on its results of operations or liquidity.

        As a condition of its license to do business in certain states, White Mountains' insurance operating subsidiaries are required to participate in mandatory shared market mechanisms. Each state dictates the types of insurance and the level of coverage that must be provided. The most common type of shared market mechanism in which White Mountains is required to participate is an assigned risk plan. Many states operate assigned risk plans. The NYAIP and New Jersey commercial automobile insurance plans are two such shared market mechanisms in which OneBeacon is required to participate. These plans require insurers licensed within the applicable state to accept the applications for insurance policies of individuals who are unable to obtain insurance in the voluntary market. The total number of such policies an insurer is required to accept is based on its market share of voluntary business in the state. Underwriting results related to assigned risk plans are typically adverse. Accordingly, OneBeacon may be required to underwrite policies with a higher risk of loss than it would otherwise accept.

        Reinsurance facilities are another type of shared market mechanism. Reinsurance facilities require an insurance company to accept all applications submitted by certain state designated agents. The

31



reinsurance facility then allows the insurer to cede some of its business to the reinsurance facility so that the facility will reimburse the insurer for claims paid on ceded business. Typically, however, reinsurance facilities operate at a deficit, which is funded through assessments against the same insurers. The Massachusetts Commonwealth Automobile Reinsurers is one such reinsurance facility in which OneBeacon is compelled to participate. As a result, OneBeacon could be required to underwrite policies with a higher risk of loss than it would otherwise accept.

        The insurance laws of many states generally provide that property and casualty insurers doing business in those states belong to a statutory property and casualty guaranty association. The purpose of these guaranty associations is to protect policyholders by requiring that solvent property and casualty insurers pay certain insurance claims of insolvent insurers. These guaranty associations generally pay these claims by assessing solvent insurers proportionately based on the insurer's share of voluntary written premiums in the state. While most guaranty associations provide for recovery of assessments through rate increases, surcharges or premium tax credits, there is no assurance that insurers will ultimately recover these assessments. At December 31, 2004, the reserve for such assessments at OneBeacon totaled $18.3 million.

        Many states have laws and regulations that limit an insurer's ability to exit a market. For example, certain states limit a private passenger automobile insurer's ability to cancel and non-renew policies. Furthermore, certain states prohibit an insurer from withdrawing from one or more lines of insurance business in the state, unless the state regulators approve the company's withdrawal plans. State regulators may refuse to approve such plans on the grounds that they could lead to market disruption. Such laws and regulations may restrict White Mountains' ability to exit unprofitable markets.

        Nearly all states have insurance laws requiring personal property and casualty insurers to file price schedules, policy or coverage forms, and other information with the state's regulatory authority. In most cases, such price schedules and/or policy forms must be approved prior to use. While pricing laws vary from state to state, their objectives are generally to ensure that prices are adequate, not excessive and not discriminatory. For example, Massachusetts, a state where OneBeacon has a sizable presence, sets virtually all aspects of automobile insurance rates, including agent commissions. Such regulations often challenge an insurers ability to adequately price its product, which often leads to unsatisfactory underwriting results.

        White Mountains' U.S. insurance and reinsurance operating subsidiaries are subject to state laws and regulations that require investment portfolio diversification and that limit the amount of investment in certain categories. Non-compliance may cause non-conforming investments to be non-admitted in measuring statutory surplus and, in some instances, may require divestiture. White Mountains investment portfolio at December 31, 2004 complied with such laws and regulations in all material respects.

        One of the primary sources of cash inflows for the Company and certain of its intermediary holding companies is dividends received from its insurance and reinsurance operating subsidiaries. Under the insurance laws of the states under which White Mountains' U.S.-based insurance and reinsurance subsidiaries are domiciled, an insurer is restricted with respect to the timing or the amount of dividends it may pay without prior approval by regulatory authorities. See "Dividend Capacity" in the "LIQUIDITY AND CAPITAL RESOURCES" section of Item 7 for further discussion.

        White Mountains is subject to regulation under certain state insurance holding company acts. These regulations contain reporting requirements relating to the capital structure, ownership, financial condition and general business operations of White Mountains' insurance and reinsurance operating subsidiaries. These regulations also contain special reporting and prior approval requirements with respect to certain transactions among affiliates. Since the Company is an insurance holding company, the domiciliary states of its insurance and reinsurance operating subsidiaries impose regulatory application and approval requirements on acquisitions of Common Shares which may be deemed to

32



confer control over those subsidiaries, as that concept is defined under the applicable state laws. Acquisition of as little as 10% of White Mountains' Common Shares may be deemed to confer control under the insurance laws of some jurisdictions, and the application process for approval can be extensive and time consuming.

        While the federal government does not directly regulate the insurance business, federal legislation and administrative policies affect the insurance industry. In addition, legislation has been introduced from time to time in recent years that, if enacted, could result in the federal government assuming a more direct role in the regulation of the insurance industry. A federal law enacted in 2002, the Terrorism Act, provides a "back-stop" to property and casualty insurers in the event of future terrorist acts perpetrated by foreign agents or interests. The law limits the industry's aggregate liability by requiring the federal government to share 90 percent of certified losses once a company meets a specific retention or deductible as determined by its prior year's direct written premiums and limits the aggregate liability to be paid by the government and industry without further action by Congress at $100 billion. In exchange for this "back-stop", primary insurers are required to make coverage available to commercial insureds for losses from acts of non-domestic terrorism as specified in the Terrorism Act. OneBeacon is actively complying with the requirements of the Terrorism Act in order to ensure its ability to be reimbursed by the federal government for any losses it may incur as a result of future terrorist acts. (See "Terrorism" in the "ONEBEACON" `section of this Item for a further discussion of the Terrorism Act.) A number of additional enacted and pending legislative measures could lead to increased consolidation and increased competition for business and for capital in the financial services industry. White Mountains cannot predict whether any state or federal measures will be adopted to change the nature or scope of the regulation of the insurance business or what effect such measures may have on its insurance and reinsurance operations.

        Environmental cleanup of polluted waste sites is subject to both federal and state regulation. The Comprehensive Environmental Response Compensation and Liability Act of 1980 ("Superfund") and comparable state statutes govern the cleanup and restoration of waste sites by potentially responsible parties ("PRPs"). These laws can impose liability for the entire cost of clean-up upon any responsible party, regardless of fault. The insurance industry in general is involved in extensive litigation regarding coverage issues arising out of the cleanup of waste sites by insured PRPs and as a result has disputed many such claims. From time to time, comprehensive Superfund reform proposals are introduced in Congress, but none has yet been enacted. At this time, it remains unclear as to whether Superfund reform legislation will be enacted or that any such legislation will provide for a fair, effective and cost-efficient system for settlement of Superfund related claims. The NICO Cover includes coverage for such exposures at OneBeacon; however, there can be no assurance that the coverage provided under the NICO Cover will ultimately prove to be adequate.


Sweden

        In accordance with provisions of Swedish law, Sirius International can voluntarily transfer its pretax earnings, or a portion thereof, subject to certain limitations, into an untaxed reserve referred to as a safety reserve. The safety reserve is a Swedish regulatory concept that has no equivalent under GAAP. Accordingly, under GAAP, an amount equal to Sirius International's safety reserve of $1.1 billion at December 31, 2004, net of the related deferred tax liability established at the statutory Swedish tax rate of 28%, is classified as equity. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain predetermined levels of premium writings in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations.

33




RATINGS

        Insurance and reinsurance companies are evaluated by various rating agencies in order to measure each company's financial strength. Higher ratings generally indicate financial stability and a stronger ability to pay claims. A.M. Best currently rates OneBeacon's, White Mountains Re's and Esurance's principal operating insurance subsidiaries "A" (Excellent, the third highest of fifteen ratings) and NFU "A-" (Excellent, the fourth highest of fifteen ratings). White Mountains believes that strong ratings are important factors in the marketing of insurance and reinsurance products to agents and consumers and ceding companies.


EMPLOYEES

        As of December 31, 2004, White Mountains employed 5,030 persons (consisting of 65 persons at the Company and its intermediate holding companies, 3,868 persons at OneBeacon, 542 persons at White Mountains Re, 542 persons at Esurance and 13 persons at the International American Group companies). Management believes that White Mountains has satisfactory relations with its employees.

        White Mountains, and the insurance and reinsurance industry in general, are subject to litigation and arbitration in the normal course of business. Other than those items listed below, White Mountains was not a party to any material litigation or arbitration other than as routinely encountered in claims activity, none of which is expected by management to have a material adverse effect on its financial condition and/or cash flows.

        In November 2004, OneBeacon Insurance Group received a subpoena from the Attorney General of the State of New York requesting documents and seeking information relating to the conduct of business between insurance brokers and OneBeacon. Subsidiaries of the Company have also received information requests from various state insurance departments regarding producer compensation arrangements. White Mountains believes these requests are part of the ongoing, industry-wide investigation regarding industry sales practices.

        On May 15, 2002, The Robert Plan Corporation and several of its subsidiaries filed a lawsuit against the Company, certain of its subsidiaries and several individuals employed by the subsidiaries. The suit alleges that the defendants misappropriated confidential information of the plaintiffs and used such information to enter into the New York automobile assigned risk business in direct competition with the plaintiffs. The plaintiffs have recently increased their damages demand from $66 million to approximately $185 million, which they allege represents two years of their lost profits in the subject business. White Mountains, its named subsidiaries and employees do not believe they engaged in any improper or actionable conduct. White Mountains and its subsidiaries have no reason to believe they have any liability to The Robert Plan Corporation and intend to vigorously defend the lawsuit. In addition, OneBeacon has brought a counterclaim against the plaintiffs that it believes to be meritorious. OneBeacon is seeking compensatory damages of $9 million as a result of the breach by the plaintiffs of the LAD servicing contract that OneBeacon had entered into with them.

        On January 30, 2001, an action was filed in Los Angeles on behalf of Sierra National Life Insurance Holdings, Inc. ("Sierra Holdings", which is not related to the Sierra Group, as previously defined), a dissolved corporation in which White Mountains held a 28.8% interest, against Credit Lyonnais, S.A. and other parties who were the successful bidders for the assets of Executive Life Insurance Company ("ELIC"), a California insurer, in the 1991 sale of those assets conducted by the California Commissioner of Insurance. Sierra Holdings alleged that defendants' acquisition violated both federal and state law and that, but for defendants' wrongful acts, it would have been chosen to purchase ELIC's assets. Sierra Holdings settled its claims against Credit Lyonnais and certain other defendants for a total of $87 million. After expenses, White Mountains share of the settlement proceeds was approximately $15 million. In addition, a default judgment regarding liability was entered at trial against another defendant, Maaf Assurances, SA, a French mutual insurer. Sierra Holdings is reviewing its options in pursuing damages against Maaf. Finally, in certain circumstances, Sierra Holdings may be entitled to additional amounts from any settlements or judgments resulting from the ongoing lawsuit by the California Commissioner of Insurance against another defendant, Artemis SA.

        In August 2000, Aramarine Brokerage, Inc. ("Aramarine"), a former insurance broker of OneBeacon's, filed a lawsuit alleging that OneBeacon had wrongfully terminated its business relationship with Aramarine. The suit originally claimed $410 million in compensatory damages for lost commissions, although Aramarine has recently reduced its demand to $158 million. OneBeacon does not believe it has engaged in any actionable conduct. During 2004, OneBeacon prevailed on a motion for summary judgment to dismiss the plaintiff's claim. OneBeacon expects the plaintiff to appeal the summary judgment upon resolution of OneBeacon's counterclaim for return commission.

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

        The following discussion contains "forward-looking statements". White Mountains intends statements which are not historical in nature, and are hereby identified as forward-looking statements, to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. White Mountains cannot promise that its expectations in such forward-looking statements will turn out to be correct. White Mountains' actual results could be materially different from and worse than its expectations. See "FORWARD-LOOKING STATEMENTS" for specific important factors that could cause actual results to differ materially from those contained in forward-looking statements.

        The following discussion also includes two non-GAAP financial measures, adjusted comprehensive net income and fully converted tangible book value per share, that have been reconciled to their most comparable GAAP financial measures (see page 55). White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains' financial performance.

RESULTS OF OPERATIONS FOR THE YEARS ENDED DECEMBER 31, 2004, 2003 and 2002

Overview

        White Mountains ended 2004 with a fully converted tangible book value per Common Share of $343, which represents an increase of 18% (including dividends) over the fully converted tangible book value per Common Share of $291 as of December 31, 2003. During 2003, fully converted tangible book value per Common Share increased by 13% (including dividends) from $259 as of December 31, 2002.

        Adjusted comprehensive net income was $539 million for 2004, compared to $360 million in 2003. Net income for 2004 was $419 million, compared to $281 million in 2003.

        The growth in book value was driven by strong investment results, particularly equities which returned 20%, and $180 million in transaction gains. This more than offset the impact of higher than expected losses from catastrophes and prior year reserve development. The growth in earnings was primarily driven by the transaction gains as both 2004 and 2003 had strong investment results.

        All three business segments performed well. OneBeacon's combined ratio in 2004 was 99%, the second consecutive year it was below 100%, and Esurance earned a profit for the first time in 2004. White Mountains Re had a combined ratio of 104% due to 11 points from catastrophes. However, the segment contributed $140 million in transaction gains and therefore was a significant contributor to the Company's growth in book value for the year.

Consolidated Results—Year Ended December 31, 2004 versus Year Ended December 31, 2003

        White Mountains' total revenues increased by 20% in 2004 compared to 2003. Growth in revenues was driven by the 22% increase in earned premiums due to the Sirius Acquisition and Atlantic Specialty transactions. Net investment income grew 24% in 2004 primarily due to the income earned on the additional invested assets acquired in the Sirius Acquisition offset by decreased net invested assets at OneBeacon.

43



        White Mountains' total expenses grew 26% for 2004 as loss and LAE, insurance acquisition and underwriting expenses were all up due to the Sirius Acquisition and Atlantic Specialty transactions. General and administrative costs were up 53% in 2004, primarily due to an increase in incentive compensation accruals, which were driven by a 41% rise in White Mountains' stock price during the year. White Mountains expenses its full cost of all incentive compensation programs. This expense is spread among loss and LAE, other underwriting expense and general and administrative expense for White Mountains' insurance and reinsurance operating subsidiaries, depending upon the function of the employees being compensated. For Other Operations, it is entirely included in general and administrative expenses.

        White Mountains' net income in 2004 also benefitted from $181 million in transaction gains: $111 million from the Sirius Acquisition, $41 million for the Symetra investment, $20 million from the Tryg-Baltica acquisition and $9 million from the Sierra Group acquisition.

Consolidated Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002

        White Mountains' total revenues decreased by 10% in 2003 compared to 2002, as an increase in earned reinsurance premiums at Folksamerica was more than offset by a decrease in earned insurance premiums at OneBeacon as a result of the business transferred to Liberty Mutual under the Liberty Agreement. Total revenues in 2003 were also impacted by decreased net investment income due to the run-off of loss reserves from OneBeacon's other businesses as well as the reduced interest rate environment. The decline in total revenues in 2003 was partially offset by an increase in other revenues, primarily as a result of $50 million in gains recorded during 2003 related to the sale of several real estate properties previously written-off under purchase accounting for OneBeacon and a $30 million increase in fees and commissions for business placed by WMU.

        Total expenses decreased by 16% in 2003 as compared to 2002, as loss and LAE, as well as insurance acquisition and other underwriting expenses, decreased at OneBeacon as a result of improved underwriting performance on its on-going businesses and as the continued run-off of unprofitable business through the Liberty Agreement. In addition, interest expense on debt decreased 32% in 2003 as a result of the repayment of the $260 million of debt in November 2002 and the refinancing of $700 million of debt in May 2003. Also contributing to the decrease in expenses was a decrease in the accretion of the fair value adjustment to the reserves acquired as part of the OneBeacon Acquisition. This accretion will continue to decrease as those acquired reserves are paid over time. Partially offsetting these expense decreases was an increase in general and administrative expense of $109 million in 2003 over 2002, primarily due to an increase in incentive compensation accruals, which were driven by a 42% rise in White Mountains' stock price during 2003.


Income Taxes

        The Company is domiciled in Bermuda and has subsidiaries domiciled in several countries. The majority of the Company's worldwide operations are taxed in the United States. Income earned or losses incurred by non-U.S. companies will generally be subject to an overall effective tax rate lower than that imposed by the United States.

        The income tax provision related to pretax earnings for 2004, 2003 and 2002 represents an effective tax rate of 19.0%, 34.3% and 9.8%, respectively. White Mountains' effective tax rate for 2004 was lower than the U.S. statutory rate of 35% primarily from income generated in jurisdictions other than the United States and from the recognition of foreign tax credits, offset by taxes incurred from an internal restructuring of the company. White Mountains' effective tax rate for 2002 was lower than the U.S. statutory rate of 35% primarily from income generated in jurisdictions other than the United States.

I. Summary of Operations By Segment

        White Mountains conducts its operations through four segments: (i) "OneBeacon", (ii) "White Mountains Re" (consisting primarily of the operations of Folksamerica, Sirius and WMU), (iii) "Esurance" and (iv) "Other Operations" (consisting of the Company and its intermediate subsidiary holding companies, White Mountains' investments in its Montpelier and Symetra warrants and the International American Group). White Mountains manages all of its investments through its wholly owned subsidiary, White Mountains Advisors LLC ("WM Advisors"), therefore, a discussion of White Mountains' consolidated investment operations is included after the discussion of operations by segment. White Mountains' segment information is presented in Note 13 to the Consolidated Financial Statements.

OneBeacon Results—Year Ended December 31, 2004 versus Year Ended December 31, 2003

Overview

        OneBeacon's pretax income for 2004 was $391 million, compared to pre-tax income of $405 million for 2003 and its GAAP combined ratio was 99% for 2004, compared to 98% for 2003. The earnings and combined ratios for each period were relatively consistent as each period had solid performance for the current underwriting year, partially offset by some adverse development in prior year's reserves. In total, adverse development was $100 million in 2004 (relating primarily to 2002 and prior accident years) and $147 million in 2003 (relating primarily to 2000 and prior accident years). The 2004 development related primarily to personal auto liability, general liability and multiple peril reserves due in part to emerging trends in claims experienced in OneBeacon's run-off operations, as

46



well as national account and program claims administered by third parties. These claim trends principally included higher defense costs and higher damages from liability assessments. The 2003 development was primarily related to construction defect claims. Adverse development in 2004 and 2003, respectively, was partially offset by the release of approximately $20 million and $30 million of the New York assigned risk liability due to the shrinking New York assigned risk pool.

        OneBeacon's total revenues for 2004 increased by 10% compared to 2003, due principally to an increase in earned premiums resulting primarily from the Atlantic Specialty Transaction. Total revenues for 2004 were also impacted by an increase in other revenues due mainly to the commencement of two new private equity funds managed by Tuckerman Capital, a group of private equity funds that are consolidated as a result of White Mountains' significant investment in the funds.

        OneBeacon's total expenses for 2004 increased 13% compared to 2003, primarily as a result of increased incentive compensation accruals driven by the 41% rise in White Mountains' share price in 2004, partially offset by the release of $20 million of the New York assigned risk liability. The release of this liability resulted from the continued effects of favorable revisions to the structure of credit programs. General and administrative expenses were higher in 2004 due mainly to the commencement of two new private equity funds managed by Tuckerman Capital, a group of private equity funds that are consolidated as a result of White Mountains' significant investment in the funds.

        During the fourth quarter of 2004, OneBeacon sold two of its subsidiaries, Potomac Insurance Company of Illinois ("Potomac") and Western States Insurance Company ("Western States"), as well as its boiler inspection service business, and recognized gains on the sales of $22 million through other revenues.

        Specialty Lines.    The specialty lines combined ratio was 90% for 2004, compared to the 2003 combined ratio of 86%. The 2004 combined ratio was higher than 2003 primarily due to losses relating to the four storms in the southeastern United States that impacted IMU and better than expected weather losses in 2003. Written premiums for specialty lines were up 16% in 2004, driven by growth in writings at OBPP and AutoOne Insurance, as well as the introduction of OBSP in 2004, a new division offering coverages to the excess and surplus property market.

        Personal Lines.    The combined ratio for personal lines for 2004 was 94%, compared to the 2003 combined ratio of 91%. The 2004 personal lines combined ratio was adversely impacted by seven points as a result of increased incentive compensation accruals, partially offset by three points due to the reduction of the New York assigned risk liability. The 2003 combined ratio benefitted by four points due to a reduction of the New York assigned risk liability. Premiums in this line grew 7% due in part to improved production of new business and increased retention levels and also $47 million in premiums assumed from New Jersey Skylands Insurance Association through a quota-share reinsurance agreement.

        Commercial Lines.    The combined ratio for commercial lines for 2004 was 97%, compared to the 2003 combined ratio of 95%. The 2004 combined ratio was a bit higher as a result of transition and integration costs related to the Atlantic Specialty Transaction and adverse results from its non-Atlantic Mutual New York commercial lines book. The 2004 loss ratio includes two points relating to the four storms in the southeastern United States, which primarily related to Atlantic Specialty business in that area. Excluding these losses, the commercial lines loss ratio significantly improved. Premiums in this line grew by 89% primarily due to the Atlantic Specialty Transaction.

        During the third quarter of 2004, OneBeacon entered into an agreement to sell the renewal rights to most of its non-Atlantic Mutual New York commercial lines business to Tower Insurance Group. The transaction, effective with December 1, 2004 renewals, will remove approximately $110 million of premiums over the next year.

OneBeacon Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002

Overview

        OneBeacon's pretax income for 2003 was $405 million, compared to pre-tax income of $200 million for 2002, and its GAAP combined ratio was 98% for 2003 compared to 107% for 2002. All of OneBeacon's ongoing businesses—specialty, personal and commercial lines—delivered combined ratios below 100% in 2003 and, in the second half of 2003, its premiums from its ongoing businesses grew for the first time since the OneBeacon Acquisition.

        OneBeacon's total revenues for 2003 declined by 21% compared to 2002, due principally to a 25% decline in earned premiums, resulting primarily from a reduction in premiums assumed under the Liberty Agreement. Total revenues for 2003 were also impacted by a 29% decrease in net investment income due to the runoff of loss reserves as well as the reduced interest rate environment. Other revenues increased significantly in 2003 due mainly to fee revenue generated by New Jersey Skylands Management LLC and certain consolidated limited partnerships.

        OneBeacon's total expenses for 2003 declined by 29% compared to 2002, primarily as a result of reduced premium writings and improved underwriting performance. Total expenses in 2003 included a net $147 million reserve increase in OneBeacon's runoff operations, primarily related to prior year construction defect claims, that was partially offset by an approximate $30 million release of the New York assigned risk liability due to the shrinking New York assigned risk pool. General and administrative expenses increased significantly in 2003 due mainly to expenses generated by New Jersey Skylands Management LLC and certain consolidated limited partnerships.

        During the fourth quarter of 2003, OneBeacon sold one of its subsidiaries, National Farmers Union Standard Insurance Company ("NFU Standard"), for $22 million and recognized a $9 million gain on the sale through other revenue.

        Specialty Lines.    The combined ratio in 2003 was 86%, a six point improvement over the 92% reported in 2002. This was driven by good underwriting results across OneBeacon's various specialty businesses, as well as favorable development in AutoOne Insurance's prior year reserves, which positively impacted the combined ratio by two points. OneBeacon wrote specialty lines premiums of $734 million in 2003, up 5% over 2002, mostly due to an increase in business written by OBPP and IMU.

        Personal Lines.    The combined ratio in 2003 was 91%, a six point improvement over the 97% reported in 2002 as price increases achieved in 2002 and 2003 flowed through into underwriting results. In addition, the 2003 period reflected the reduction in OneBeacon's New York assigned risk liability, discussed above, which lowered the combined ratio by three points. OneBeacon's personal lines written premium volume for 2003 decreased 20% from 2002, primarily due to re-underwriting efforts such as actions to reduce exposure to windstorms on property located in coastal areas. Also contributing to the decrease were declines in written premiums relating to the transfer of OneBeacon's private passenger automobile business in New Jersey to New Jersey Skylands Insurance Association in 2002.

        Commercial Lines.    The combined ratio in 2003 was 95%, a five point improvement over the 100% reported in 2002 as the Company's efforts to re-underwrite its book took hold, partially offset by prior year reserve development of three points. OneBeacon's commercial lines written premium volume for 2003 decreased 6% from 2002, primarily due to the continued effects of actions taken to reduce the concentration of risks subject to terrorism, such as reducing total insured values in 11 major cities, and reductions in workers compensation writings.

        Run-off Operations.    Pursuant to the Liberty Agreement, Liberty Mutual assumed control of OneBeacon's claims offices in the regions subject to the Liberty Agreement and was responsible for servicing claims from the OneBeacon policies written prior to November 1, 2001, as well as policies

48



which renewed in those regions since that date. Effective July 11, 2003, the servicing agreement with Liberty Mutual was amended and OneBeacon took back substantially all remaining outstanding claims related to policies written prior to the Liberty Agreement.

        During the second quarter of 2003, OneBeacon claims and actuarial personnel noticed an unusual spike in case reserves related to the policies taken back from Liberty Mutual. The spike was isolated primarily to incurred losses on construction defect claims which were approximately $38 million higher than expected. There were 924 new claims, 32% higher than expected. The four states with the largest number of new construction defect claims were California, Nevada, Colorado and Arizona (345 of the total 924 new claims). As a result, OneBeacon claims and actuarial personnel undertook a study to determine the cause of the increase. This study, which was completed in the third quarter of 2003, indicated that most of the increase in activity was due to differences in case reserving philosophies between OneBeacon's and Liberty's claims adjusters, such as the identification and coding of construction defect claims. However, the study also indicated that some of the increase in activity related to an increase in the severity of construction defect claims stemming from increased litigation and resulting adverse court decisions. As a result, OneBeacon recorded an increase for construction defect claim reserves of $98 million in the third quarter of 2003. See Construction Defect Claims in CRITICAL ACCOUNTING ESTIMATES below for further background on construction defect claims.

White Mountains Re Results—Year Ended December 31, 2004 versus Year Ended December 31, 2003

        White Mountains Re's GAAP combined ratio increased from 96% in 2003 to 104% in 2004, due primarily to $135 million of claims incurred related to significant property catastrophe events in the second half of 2004. These catastrophes, which are discussed further below, increased the combined ratio in 2004 by 11 points. In general, White Mountains Re has experienced favorable underwriting conditions for the past three underwriting years. Earnings from business segments not impacted by the property catastrophe events, and earnings from the recently completed Sirius Acquisition, have partially offset the impact of these natural disasters. Net written premiums, total revenues, and total expenses were all up substantially in 2004 due to the Sirius Acquisition.

        Gross written premiums increased $518 million, or 37% from 2003 to 2004, and net written premiums increased $361 million, or 41% for the same period. This increase is due primarily to the Sirius Acquisition, which contributed $612 million of gross written premiums and $418 million of net written premiums during 2004. Included in these amounts is the U.S. program business written by Sirius America totaling $216 million of gross written premiums and $85 million of net written premiums. Additionally, in late 2003, White Mountains Re, through Folksamerica, entered into the CNA Re agreement and established a Chicago underwriting office. Annual gross written premiums for the 2004 underwriting year resulting from this transaction and the related opening of the Chicago underwriting office were approximately $177 million, of which $129 million was recorded as gross written premium and $91 million as net written premium for the year ended December 31, 2004. Partially offsetting the increases resulting from these transactions was the cancellation of several large casualty treaties at Folksamerica whose pricing or terms did not meet White Mountains Re's underwriting guidelines.

        There were significant levels of property catastrophe activity during the last half of 2004, including the four hurricanes which affected the Southeast United States and the Caribbean, where White Mountains Re has historically been a significant participant in the property reinsurance market. Additionally, Sirius International was exposed to losses from the devastating tsunami that impacted South Asia in December 2004. White Mountains Re believes its underwriting discipline and risk management approach helped to contain these losses to manageable levels. This significant property catastrophe activity during the last half of 2004 resulted in $135 million of pre-tax losses, including $16 million related to the tsunami. There was no significant property catastrophe activity in 2003.

        During 2004, White Mountains Re recorded $11 million of net unfavorable loss reserve development, which contributed 1 point to the loss ratio in 2004, as compared to $46 million, or 5 points in 2003. The 2003 unfavorable development is described in further detail in the section titled White Mountains Re Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002, below. The majority of the unfavorable development recorded in 2004 resulted from certain discontinued lines at Folksamerica as well as run-off operations acquired as part of the Sirius Acquisition. This unfavorable development was partially offset by favorable development in the Sirius International reserve portfolio, stemming mainly from the three most recent underwriting years, and is indicative of the favorable terms and conditions that have existed in the global reinsurance marketplace during that time. Additionally, White Mountains Re recorded $10 million of unfavorable loss development on its workers compensation reserves acquired as part of the Sierra acquisition in 2004. This adverse development was offset dollar-for-dollar by the adjustable note discussed in Note 2—Significant Transactions.

        White Mountains Re receives fee income on reinsurance placements referred to Olympus and is entitled to a profit commission based on net underwriting profits on referred business. The additional capacity provided by the reinsurance relationship with Olympus supports White Mountains Re's ability to offer significant reinsurance protection. White Mountains Re recognized net fee income of $69 million from Olympus in 2004 as compared to $98 in 2003. The decline in the fee income earned is

50



due primarily to the negative impact of the four hurricanes on the profit commission arrangement between White Mountains Re and Olympus.

White Mountains Re Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002

        White Mountains' Re's pretax income was $144 million for 2003, an increase of 40% over the $103 million recorded in 2002. White Mountains Re's GAAP combined ratio improved to 96% for 2003, from 102% for 2002. The improvement in White Mountains Re's combined ratio resulted primarily from more favorable terms and conditions in the reinsurance marketplace, and fewer catastrophe losses affecting White Mountains Re in 2003 as compared to 2002.

        White Mountains Re's gross written premiums increased 44% from 2002 to 2003, while net written premiums increased 29% and earned premiums increased 33%. The increases in net written and earned premiums were due to increased pricing on White Mountains Re's expiring and renewed contracts, increased shares on renewed contracts and new contracts resulting from the increased demand of reinsurance buyers for placing reinsurance with responsible, well-capitalized reinsurers.

        White Mountains Re's total revenues were up 27% in 2003 over 2002, primarily driven by a 33% increase in earned premiums. The increase in earned (and net written) premiums was due to increased pricing on White Mountains Re's expiring and renewed contracts, increased shares on renewed contracts and new contracts resulting from the increased demand of reinsurance buyers for placing reinsurance with responsible, well-capitalized reinsurers. Also contributing to the increase in revenues in 2003 was a $49 million increase ($98 million in 2003 vs $49 million in 2002) in advisory fees and profit commissions received by White Mountains Re on reinsurance placements referred to Olympus, due principally to an increase in the volume of business ceded to Olympus in 2003.

        White Mountains Re experienced approximately $46 million of unfavorable loss reserve development during 2003, primarily due to strengthening of A&E reserves and reserves on Risk Capital casualty lines. White Mountains Re's 2003 loss development for A&E exposures was due to the completion of a detailed A&E market share study. This study compared Folksamerica's share of industry paid losses to estimated industry carried reserves and resulted in Folksamerica increasing its IBNR by approximately $25 million.

Esurance Results—Year Ended December 31, 2004 versus Year Ended December 31, 2003

        Esurance's pretax income of $4 million for 2004 represented an improvement over the pretax loss of $19 million in 2003. Esurance's 2004 combined ratio improved to 102% from 120% in 2003 due to improvements in both loss and expense ratios. Esurance's loss ratio improvement resulted from the continued rollout and refinement of Esurance's proprietary auto insurance program. Loss ratio improvement also resulted from better claims performance, driven by the transition from a third party administrator to an in-house claims operation in 2003, as well as 3 points of favorable development on loss reserves.

        The auto program, combined with Esurance's self-service, web-enabled operating platform, allowed Esurance to increase premium volume and in-force policy count while reducing the expense ratio from 39% to 33%. As of December 31, 2004, Esurance's in-force count was 118,513 policies, a 60% increase over December 31, 2003. Increased advertising, particularly in radio and TV, drove policy count growth.

Esurance Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002

        The trends described above that drove Esurance's favorable results in 2004 relative to 2003 also benefitted the 2003 results in relation to 2002. Thus, the pretax loss for Esurance decreased by $7 million in 2003 and the combined ratio fell 49 points, while net written premiums more than doubled.

        White Mountains' capital raising and capital allocation activities are principally conducted through its holding companies. In this regard, the results of its Other Operations segment primarily relate to financing activities, purchase accounting adjustments relating to the OneBeacon Acquisition, gains and losses recognized from the purchase and sale of certain of the Company's subsidiaries and other assets and general and administrative expenses incurred at the holding company level.

Other Operations Results—Year Ended December 31, 2004 versus Year Ended December 31, 2003

        White Mountains' Other Operations segment reported a pre-tax loss of $235 million for 2004, compared to $159 million for 2003. The increased loss for the year was primarily due to a $20 million increase in incentive compensation accruals, which were driven by a 41% rise in White Mountains' stock price during 2004, and higher gains from the sale of real estate in 2003 ($13 million in 2004 and $43 million in 2003). In addition, interest expense on preferred stock was up $25 million in 2004 due to the inclusion of a full year of expense in pre-tax income in 2004 as opposed to six months included in 2003 as a result of the Company's adoption of SFAS 150, effective July 1, 2003. Prior to the adoption of SFAS 150, the interest expense on preferred stock was classified below the pretax loss line on the income statement as preferred stock dividends.

        During the periods presented, Peninsula was the only operating company in the segment, and therefore it accounts for all of the premiums reported in the tables above. During January 2004, White Mountains sold Peninsula for $23 million. The operations of American Centennial and British Insurance Company are not significant to White Mountains, as those companies have been in run-off since they were acquired in 1999.

53



Other Operations Results—Year Ended December 31, 2003 versus Year Ended December 31, 2002

        White Mountains' Other Operations segment reported pre-tax losses of $159 million for both 2003 and 2002. Incentive compensation accruals increased by $72 million in 2003, but this increase was offset by, among other items, a $43 million decrease in losses on interest rate swap agreements and a $31 million decrease in the accretion of the fair value adjustment on loss reserves acquired in the OneBeacon Acquisition. Interest expense on debt decreased by $24 million in 2003, due to the pay-off of a $260 million loan and the refinancing of $700 million of senior debt and amortization of the previous credit facility. This decrease was offset by the inclusion of $22 million of interest expense on preferred stock as a result of SFAS 150.

II.    Summary of Investment Results

Investment Philosophy

        White Mountains manages all of its consolidated investments through its wholly-owned subsidiary, WM Advisors. White Mountains' investment philosophy is to invest its assets with a view towards maximizing its after-tax total return over extended periods of time. Under this approach, each dollar of after-tax investment income and realized and unrealized gains and losses is valued equally. White Mountains' overall fixed maturity investment strategy is to purchase securities that are attractively priced in relation to perceived credit risks. White Mountains generally manages the interest rate risk associated with holding fixed maturity investments by actively monitoring and maintaining the average duration of the portfolio with the goal of achieving an adequate after-tax total return without subjecting the portfolio to an unreasonable level of interest rate risk. White Mountains' investment portfolio mix as of December 31, 2004 consisted in large part of high-quality, fixed maturity investments and short-term investments, as well as some equity investments and limited partnerships. White Mountains' management believes that prudent levels of investments in common equity securities and other investments within its investment portfolio are likely to enhance after-tax total returns without significantly increasing the risk profile of the portfolio when considered over long periods of time when balanced with leverage and insurance risk considerations. White Mountains seeks to maximize after-tax risk-adjusted returns over the long term.


Investment Returns

        White Mountains generated strong investment returns in 2004. The GAAP total return on invested assets was 7%, while the equity portfolio returned 20% for the year. The equity return was significantly better than the S&P 500, which returned 11% for the year, while the bond portfolio performed in line with its duration and credit characteristics. Management is continuing to keep its fixed maturity portfolio duration relatively short at about 3 years to reflect its concern that interest rates may rise in the next few years. Net investment income was up 24% from last year mainly due to the Sirius Acquisition, after declining 21% in 2003 primarily due to the decline in reserves at OneBeacon as its premium volume was reduced.

        White Mountains sold a portion of its investment in Montpelier common shares during the first quarter of 2004 resulting in a $35 million pre-tax realized gain and, as a result, changed the method of accounting for its remaining Montpelier common shares to the fair value method, resulting in a $33 million increase in after-tax unrealized gains in the first quarter.

Impairment

        See Note 5—Investments of the accompanying consolidated financial statements for White Mountains' analysis of impairment losses on investment securities.

NON-GAAP FINANCIAL MEASURES

        This report includes two non-GAAP financial measures that have been reconciled to their most comparable GAAP financial measures. White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains' financial performance.

        Adjusted comprehensive net income is a non-GAAP measure that excludes the change in net unrealized gains from Symetra's fixed maturity portfolio from comprehensive net income. GAAP requires these assets to be marked-to-market, which results in gains during periods when interest rates fall and losses in periods when interest rates rise. Because the liabilities related to the life insurance and structured settlement products that these assets support are not marked-to-market, it is likely that the economic impact on Symetra would be the opposite of that shown under GAAP (i.e., in general, Symetra's intrinsic value increases when interest rates rise and decreases when interest rates fall). The reconciliation of adjusted comprehensive net income to comprehensive net income is included on page 43.

        Book value per share is derived by dividing the Company's total GAAP shareholders' equity as of a given date by the number of Common Shares outstanding as of that date, including the dilutive effects of outstanding Options and warrants to acquire Common Shares, as well as the unamortized accretion of preferred stock. Fully converted tangible book value per share is a non-GAAP measure which is derived by expanding the GAAP book value per share calculation to include the effects of assumed conversion of all convertible securities and to exclude any unamortized goodwill and net unrealized gains from Symetra's fixed maturity portfolio. The reconciliation of fully converted tangible book value per share to book value per share is included on page 42.


LIQUIDITY AND CAPITAL RESOURCES

Operating cash and short-term investments

        Holding company level.    The primary sources of cash for the Company and certain of its intermediate holding companies are dividends and tax sharing payments received from its insurance and reinsurance operating subsidiaries, financing activities and net investment income and proceeds from sales and maturities of holding company investments. The primary uses of cash are interest payments on the Senior Notes, dividend payments on the Berkshire and Zenith Preferred Stock as well as on Common Shares, purchases of investments and holding company operating expenses.

        Operating subsidiary level.    The primary sources of cash for White Mountains' insurance and reinsurance operating subsidiaries are premium collections, net investment income and proceeds from sales and maturities of investments. The primary uses of cash are claim payments, policy acquisition costs, operating expenses, the purchase of investments and dividend and tax sharing payments made to parent holding companies.

        Both internal and external forces influence White Mountains' financial condition, results of operations and cash flows. Claim settlements, premium levels and investment returns may be impacted by changing rates of inflation and other economic conditions. In many cases, significant periods of time, ranging up to several years or more, may lapse between the occurrence of an insured loss, the reporting of the loss to White Mountains and the settlement of the liability for that loss. The exact timing of the payment of claims and benefits cannot be predicted with certainty. White Mountains' insurance and reinsurance operating subsidiaries maintain portfolios of invested assets with varying maturities and a substantial amount of short-term investments to provide adequate cash for the payment of claims.

        Management believes that White Mountains' cash balances, cash flows from operations, routine sales of investments and the liquidity provided by its Bank Facility are adequate to meet expected cash requirements for the foreseeable future on both a holding company and insurance and reinsurance operating subsidiary level.

55




Dividend Capacity

        Under the insurance laws of the states and jurisdictions under which White Mountains' insurance and reinsurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing or the amount of dividends it may pay without prior approval by regulatory authorities. Accordingly, there can be no assurance regarding the amount of such dividends that may be paid by such subsidiaries in the future. Following is a description of the ability of White Mountains' insurance and reinsurance operating subsidiaries to pay dividends to the Company and certain of its intermediate holding companies:

OneBeacon:

        Generally, OneBeacon's regulated insurance operating subsidiaries have the ability to pay dividends during any 12 month period without the prior approval of regulatory authorities in an amount equal to the greater of prior year statutory net income or 10% of prior year end statutory surplus, subject to the availability of unassigned funds. As a result, based on 2004 statutory net income, OneBeacon's top tier regulated insurance operating subsidiaries have the ability to pay $325 million of dividends during 2005 without prior approval of regulatory authorities, subject to the availability of unassigned funds. As of December 31, 2004, OneBeacon's top tier regulated insurance operating subsidiaries had $1.3 billion of unassigned funds available for dividend distribution.

        In addition, as of December 31, 2004, OneBeacon had $195 million of cash and investments outside of its regulated insurance operating subsidiaries available for distribution during 2005. During 2004, OneBeacon paid $305 million of cash dividends to Fund American.

White Mountains Re:

        Folksamerica's principal regulated reinsurance operating subsidiary has the ability to pay dividends during any 12 month period without the prior approval of regulatory authorities in an amount equal to the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. As a result, based upon December 31, 2004 statutory surplus of $917 million, Folksamerica's principal regulated reinsurance operating subsidiary would have the ability to pay approximately $92 million of dividends during 2005 without prior approval of regulatory authorities, subject to the availability of earned surplus. As of December 31, 2004, Folksamerica's principal regulated reinsurance operating subsidiary had $17 million of earned surplus, therefore it can pay dividends of $17 million plus additional earned surplus reported during 2005, subject to the $92 million limitation discussed above.

        As of December 31, 2004, WMU had $3 million of cash and investments available for distribution during 2005. In addition, WMU has the ability to distribute its 2005 earnings without restriction. During 2004, WMU paid $60 million of cash dividends to its immediate parent.

        In addition, as of December 31, 2004, White Mountains Re had approximately $97 million of cash and investments outside of its regulated insurance and reinsurance operating subsidiaries available for distribution during 2005.


Safety Reserve

        In accordance with provisions of Swedish law, Sirius International can voluntarily transfer its pretax earnings, or a portion thereof, subject to certain limitations, into an untaxed reserve referred to as a safety reserve. The safety reserve is a Swedish regulatory concept that has no equivalent under GAAP. Accordingly, under GAAP, an amount equal to Sirius International's safety reserve of $1.1 billion at December 31, 2004, net of the related deferred tax liability established at the statutory Swedish tax rate of 28%, is classified as equity. Generally, this deferred tax liability is only required to be paid by Sirius

56



International if it fails to maintain predetermined levels of premium writings in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations.


Keep-Well

        On November 30, 2004, White Mountains completed a significant corporate reorganization, through which ownership of Folksamerica was transferred to White Mountains Re from Fund American. In order to effect the reorganization, White Mountains and Fund American entered into or amended certain agreements with respect to the Berkshire Preferred Stock. Under the terms of a Keep-Well Agreement dated November 30, 2004 between White Mountains and Fund American (the "Keep-Well"), White Mountains has agreed to return to Fund American up to approximately $1.1 billion, which equals the amount of net assets transferred out of Fund American as a result of the reorganization, if some or all of that amount is required by Fund American to meet its obligations to Berkshire under the Berkshire Preferred Stock. Additionally, the Keep-Well limits the aggregate amount of distributions that White Mountains may make to its shareholders to approximately $1.3 billion plus White Mountains' aggregate consolidated net income after September 30, 2004. The Keep-Well will expire when all obligations of the Berkshire Preferred Stock, which is redeemable in May 2008, have been satisfied, or when approximately $1.1 billion has been returned to Fund American.


Insurance Float

        Insurance float is an important dynamic of White Mountains' operations that must be managed effectively. Float is money that an insurance company holds for a limited time. In an insurance operation, float arises because premiums are collected before losses are paid. This interval can extend over many years. During that time, the insurer invests the money. When the premiums that an insurer collects do not cover the losses and expenses it eventually must pay, the result is an underwriting loss, which is considered to be the cost of float. The amount and cost of float for White Mountains is affected by underlying market conditions, as well as acquisitions or dispositions of insurance and reinsurance businesses. Although insurance float can be calculated using numbers determined under GAAP, insurance float is not a GAAP concept and therefore there is no comparable GAAP measure.

57


        One of the means by which White Mountains calculates its insurance float is by taking its net investment assets and subtracting its total tangible capital. The following table illustrates White Mountains' consolidated insurance float position as of the past five year-ends:

        White Mountains has historically obtained its float primarily through acquisitions, as opposed to organic growth. For each of the years in the three-year period ending December 31, 2004, White Mountains has had negative cash flows from operations but has generated significant float from its insurance and reinsurance operations. This is due to the fact that White Mountains' cash flow from operations does not reflect cash and investments generated by the acquisition of insurance and

58



reinsurance businesses in recent years. Post-acquisition, such companies are often placed into partial or complete run-off, thereby resulting in negative cash flows from operations as the investments acquired are liquidated over time to pay claims.

        In the case of OneBeacon, the substantial amount of float initially acquired with the OneBeacon Acquisition has shrunk as a result of OneBeacon's re-underwriting efforts and the effects of the Liberty Agreement. OneBeacon's float is expected to continue to shrink during 2005 as older, long-tailed loss reserves are paid and are not replaced with the same level of current writings as those written in the past. In the case of White Mountains Re, its float increased substantially in 2004 as a result of the Sirius and Sierra acquisitions. White Mountains Re's float is expected to increase during 2005 as a result of higher premium writings from its increased capital base and acquisitions over the past few years.

        It is White Mountains' intention to generate low-cost float over time through a combination of acquisitions and/or by organic growth in its existing insurance and reinsurance operations. However, White Mountains will seek to increase its float organically only when market conditions allow for an expectation of generating underwriting profits.

See Note 6—Debt of the accompanying Consolidated Financial Statements for a discussion of operating subsidiary debt.

        Management believes that White Mountains' strong financial position provides it with the flexibility and capacity to obtain funds externally as needed through debt or equity financing on both a short-term and long-term basis. In May 2003, White Mountains reduced its cost of capital and significantly reduced its near-term obligations by fully prepaying its previous $740 million amortizing bank facility, principally through the net proceeds from the issuance of the Senior Notes, which were issued by Fund American through a public offering. The Senior Notes bear a fixed annual interest rate of 5.9% and mature in May 2013. In July 2003, White Mountains enhanced its access to the capital markets by having a shelf registration declared effective by the SEC for offerings of up to $2.0 billion in debt and/or equity securities.

59



        In August 2004, Fund American restructured and re-syndicated its existing $300 million Bank Facility to increase the availability under the revolving credit facility to $400 million and to extend the maturity from September 2006 to August 2009. Under the Bank Facility, for which both Fund American and the Company are permitted borrowers, the Company guarantees all obligations of Fund American, and Fund American guarantees all borrowings of the Company, subject to certain limitations imposed by the terms of the Berkshire Preferred Stock. As of December 31, 2004, the Bank Facility was undrawn.

        In connection with its acquisition of the Sierra Group on March 31, 2004, Folksamerica entered into a $62 million purchase note (the "Sierra Note"), $58 million of which will be adjusted over its approximate six-year term to reflect favorable or adverse loss reserve development on the acquired reserve portfolio and run-off of remaining policies in force (mainly workers compensation business) as well as certain other balance sheet protections. During 2004, the Sierra Note was reduced by $12 million as a result of adverse development on the acquired reserves and run-off of unearned premiums.

        In connection with its acquisition of Atlantic Specialty on March 31, 2004, OneBeacon issued a $20 million ten-year note to the seller (the "Atlantic Specialty Note"). OneBeacon is required to repay $2 million of principal on the notes per year, commencing with the first payment due on January 1, 2007.

        Fund American's Senior Notes are currently rated "Baa2" (Adequate, the 9th highest of 21 ratings) with a stable outlook by Moody's and "BBB-" (Adequate, the 10th highest of 24 ratings) with a positive outlook by S&P and "BBB" (Good, the 9th highest of 24 ratings) with a stable outlook by Fitch Ratings. It is possible that, in the future, one or more of the rating agencies may lower White Mountains' existing ratings. If one or more of its ratings were downgraded, White Mountains could incur higher borrowing costs and its ability to access the capital markets could be impacted. In addition, White Mountains' insurance and reinsurance operating subsidiaries could be adversely impacted by a downgrade in their financial strength ratings, including a possible reduction in demand for their products in certain markets.

        The Senior Notes were issued under an indenture which contains restrictive covenants that, among other things, limit the ability of the Company, Fund American and their respective subsidiaries to create liens and enter into sale and leaseback transactions and substantially limits the ability of Fund American and its respective subsidiaries to consolidate, merge or transfer their properties and assets. The indenture does not contain any financial ratios or specified levels of net worth or liquidity to which the Company or Fund American must adhere. At December 31, 2004, White Mountains was in compliance with all of the covenants under the Senior Notes, and anticipates it will continue to remain in compliance with these covenants for the foreseeable future.

        The Bank Facility contains various affirmative, negative and financial covenants which White Mountains considers to be customary for such borrowings and include maintaining certain minimum net worth and maximum debt to capitalization standards for White Mountains. Failure to meet one or more of these covenants could result in an event of default, which ultimately could eliminate availability under the facility and result in acceleration of principal repayment on any amounts outstanding. At December 31, 2004, White Mountains was in compliance with all of the covenants under the Bank Facility, and anticipates it will continue to remain in compliance with these covenants for the foreseeable future.

Represents expected future cash outflows resulting from loss and LAE payments. Accordingly, these balances exclude the discount on OneBeacon's workers compensation loss and LAE reserves of $259.4 million and the remaining purchase accounting fair value adjustment of $409.6 million related to the OneBeacon and Sirius acquisitions as they are non-cash items. Further, the amounts presented include reinsurance recoverables recorded of $3,797.4 million.

        White Mountains' loss reserves do not have contractual maturity dates. However, based on historical payment patterns, the preceding table includes an estimate of when management expects White Mountains' loss reserves to be paid. The timing of claim payments is subject to significant uncertainty. White Mountains maintains a portfolio of marketable investments with varying maturities and a substantial amount of short-term investments to provide adequate cash flows for the payment of claims.

        The balances included in the table above regarding White Mountains' long-term incentive compensation plans include amounts payable for performance shares and units, as well as deferred compensation balances. Exact amounts to be paid cannot be predicted, for performance shares, with certainty, as the ultimate amounts of these liabilities are based on future performance of the Company and the market price of Common Shares at the time the payments are made. The estimated payments reflected in the table are based on current accrual factors (Common Share price and pay-out percentage) and assume that all outstanding balances were 100% vested as of December 31, 2004.

        There are no provisions within White Mountains' leasing agreements that would trigger acceleration of future lease payments. White Mountains does not finance its operations through the securitization of its trade receivables, through special purpose entities or through synthetic leases. Further, White Mountains has not entered into any material arrangement requiring it to guarantee payment of third party debt, lease payments or to fund losses of an unconsolidated special purpose entity, except as noted in the following paragraph.

        Through Sirius International, White Mountains has a long term investment as a stockholder in LUC Holdings, an entity that has entered into a head lease to rent the London Underwriting Center ("LUC") through 2016. LUC Holdings in turn subleases space in the LUC. In the LUC Holdings stockholders agreement, the stockholders have guaranteed any shortfall between the head lease and the sub-leases on a joint and several basis. As a consequence, in recent years the stockholders have funded an operating shortfall of LUC. At December 31, 2004, White Mountains has recorded a liability of $10 million for its share of the expected future shortfall between LUC Holdings' head lease payments

61



and sub-lease receipts. White Mountains does not believe that future shortfalls, if any, will have a material impact on its results of operations.

        White Mountains also has future binding commitments to fund certain limited partnership investments. These commitments, which total approximately $25.9 million, do not have fixed funding dates and are therefore excluded from the table above.

RELATED PARTY TRANSACTIONS

        See Note 17—"Related Party Transactions" in the accompanying Consolidated Financial Statements.


CRITICAL ACCOUNTING ESTIMATES

        Management's Discussion and Analysis of Financial Condition and Results of Operations discusses the Company's consolidated financial statements, which have been prepared in accordance with GAAP.

64



The financial statements presented herein include all adjustments considered necessary by management to fairly present the financial position, results of operations and cash flows of White Mountains. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.

        In the current year presentation of financial information, certain amounts in the prior period financial statements have been reclassified to conform with the current presentation. White Mountains has completed numerous significant transactions during the periods presented that have affected the comparability of the financial statement information presented herein.

        On an ongoing basis, management evaluates its estimates, including those related to loss and LAE reserves, purchase accounting, reinsurance estimates and its pension benefit obligations. Management bases its estimates on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgements about the carrying values of assets and liabilities that are not readily apparent from other sources.

        Management believes that its critical accounting policies affect its more significant estimates used in the preparation of its consolidated financial statements. The descriptions below are summarized and have been simplified for clarity.


1.    Loss and Loss Adjustment Expenses

OneBeacon

        OneBeacon establishes loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain.

        Reserves are typically comprised of (1) case reserves for claims reported and (2) reserves for losses that have occurred but for which claims have not yet been reported, referred to as incurred but not reported ("IBNR") reserves, which include a provision for expected future development on case reserves. Case reserves are estimated based on the experience and knowledge of claims staff regarding the nature and potential cost of each claim and are adjusted as additional information becomes known or payments are made. IBNR reserves are derived by subtracting paid loss and LAE and case reserves from estimates of ultimate loss and LAE. Actuaries estimate ultimate loss and LAE using various generally accepted actuarial methods applied to known losses and other relevant information. Like case reserves, IBNR reserves are adjusted as additional information becomes known or payments are made.

        Ultimate loss and LAE are generally determined by extrapolation of claim emergence and settlement patterns observed in the past that can reasonably be expected to persist into the future. In forecasting ultimate loss and LAE with respect to any line of business, past experience with respect to that line of business is the primary resource, but cannot be relied upon in isolation. OneBeacon's own experience, particularly claims development experience, such as trends in case reserves, payments on and closings of claims, as well as changes in business mix and coverage limits, is the most important information for estimating its reserves. External data, available from organizations such as statistical bureaus, consulting firms and reinsurance companies, is sometimes used to supplement or corroborate OneBeacon's own experience, and can be especially useful for estimating costs of new business. For some lines of business, such as "long-tail" coverages discussed below, claims data reported in the most recent accident year is often too limited to provide a meaningful basis for analysis due to the typical delay in reporting of claims. For this type of business, OneBeacon uses a selected loss ratio method for the initial accident year or years. This is a standard and accepted actuarial reserve estimation method

65



in these circumstances in which the loss ratio is selected based upon information used in pricing policies for that line of business, as well as any publicly available industry data, such as industry pricing, experience and trends, for that line of business.

        Uncertainties in estimating ultimate loss and LAE are magnified by the time lag between when a claim actually occurs and when it is reported and settled. This time lag is sometimes referred to as the "claim-tail". The claim-tail for most property coverages is typically short (usually a few days up to a few months). The claim-tail for liability/casualty coverages, such as automobile liability, general liability, products liability, multiple peril coverage, and workers compensation, can be especially long as claims are often reported and ultimately paid or settled years, even decades, after the related loss events occur. During the long claims reporting and settlement period, additional facts regarding coverages written in prior accident years, as well as about actual claims and trends may become known and, as a result, OneBeacon may adjust its reserves. If management determines that an adjustment is appropriate, the adjustment is booked in the accounting period in which such determination is made in accordance with GAAP. Accordingly, should reserves need to be increased or decreased in the future from amounts currently established, future results of operations would be negatively or positively impacted, respectively.

        In determining ultimate loss and LAE, the cost to indemnify claimants, provide needed legal defense and other services for insureds and administer the investigation and adjustment of claims are considered. These claim costs are influenced by many factors that change over time, such as expanded coverage definitions as a result of new court decisions, inflation in costs to repair or replace damaged property, inflation in the cost of medical services and legislated changes in statutory benefits, as well as by the particular, unique facts that pertain to each claim. As a result, the rate at which claims arose in the past and the costs to settle them may not always be representative of what will occur in the future. The factors influencing changes in claim costs are often difficult to isolate or quantify and developments in paid and incurred losses from historical trends are frequently subject to multiple and conflicting interpretations. Changes in coverage terms or claims handling practices may also cause future experience and/or development patterns to vary from the past. A key objective of actuaries in developing estimates of ultimate loss and LAE, and resulting IBNR reserves, is to identify aberrations and systemic changes occurring within historical experience and accurately adjust for them so that the future can be projected reliably. Because of the factors previously discussed, this process requires the use of informed judgment and is inherently uncertain.

        OneBeacon's actuaries use several generally accepted actuarial methods to evaluate its loss reserves, each of which has its own strengths and weaknesses. OneBeacon places more or less reliance on a particular method based on the facts and circumstances at the time the reserve estimates are made. These methods generally fall into one of the following categories or are hybrids of one or more of the following categories:

66


        OneBeacon's general liability and multiple peril lines of business have been significantly impacted by an increasing number of construction defect claims. Construction defect is a liability allegation relating to defective work performed in the construction of structures such as apartments, condominiums, single family dwellings or other housing, as well as the sale of defective building materials. Such claims seek recovery due to damage caused by alleged deficient construction techniques or workmanship. Much of the increase in claims activity has been generated by plaintiffs' lawyers who approach new homeowners, and in many cases homeowner associations with large numbers of homeowners in multi-residential complexes, about defects or other flaws in their homes. The increasing number of claims for construction defects began with claims relating to exposures in California. Then, as plaintiffs' lawyers organized suits in other states with high levels of multi-residential construction, construction defect claims were reported in nearby western states, such as Colorado and Nevada, and eventually throughout the country. The reporting of such claims can be quite delayed as the statute of limitations can be up to ten years. Court decisions have expanded insurers' exposure to construction defect claims as well. For example, in 1995 California courts adopted a "continuous trigger" theory in which all companies that had ever insured a property that was alleged to have been damaged by defective construction must respond to the claimant, even if evidence of the alleged damage did not appear until after the insurance period had expired. As a result, claims may be reported more than ten years after a project has been completed as litigation can proceed for several years before an insurance company is identified as a potential contributor. Recently, claims have also emerged from parties claiming additional insured status on policies issued to other parties (e.g., such as contractors seeking coverage on a sub-contractor's policy).

67


        A large number of construction defect claims have been identified relating to coverages that OneBeacon had written in the past through Commercial Union and General Accident and their subsidiaries in California, Colorado, Nevada, Washington and Oregon. Management has sought to mitigate future construction defect risks in all states by no longer providing insurance to certain residential general contractors and sub-contractors involved in multi-habitational projects. Mitigating actions also included initiating the withdrawal from problematic sub-segments within OneBeacon's construction book of business, such as street and road construction, water, sewer and pipeline construction, and dam, waterway, railroad and subway construction. Management has undertaken actions to mitigate future risks related to construction defect claims and believes that the number of reported construction defect claims relating to coverages written in the past peaked in 2004 and will begin to decline. In addition, in reserving for these claims, there is additional uncertainty due to the potential for further unfavorable judicial rulings and regulatory actions.

        OneBeacon's reserves include provisions made for claims that assert damages from A&E related exposures. Asbestos claims relate primarily to injuries asserted by those who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up cost obligations, particularly as mandated by federal and state environmental protection agencies. In addition to the factors described above under "Non-Asbestos and Environmental Reserves" regarding the reserving process, OneBeacon estimates its A&E reserves based upon, among other factors, facts surrounding reported cases and exposures to claims, such as policy limits and deductibles, current law, past and projected claim activity and past settlement values for similar claims, as well as analysis of industry studies and events, such as recent settlements and asbestos-related bankruptcies. The cost of administering A&E claims, which is an important factor in estimating loss reserves, tends to be higher than in the case of non-A&E claims due to the higher legal costs typically associated with A&E claims. Due to the inherent difficulties in estimating ultimate A&E exposures, OneBeacon does not estimate a range for A&E incurred losses.

        OneBeacon's A&E losses resulted primarily from the operations of the Employers Group, an entity acquired by one of the legacy companies in 1971. These operations, including business of Employers Surplus Lines Insurance Company and Employers Liability Assurance Corporation, provided primary and excess liability insurance for commercial insureds, including Fortune 500-sized accounts, some of whom subsequently experienced claims for A&E losses. OneBeacon stopped writing such coverage in 1984.

        OneBeacon's liabilities for A&E losses from business underwritten in the recent past are substantially limited by the application of exclusionary clauses in the policy language that eliminated coverage of such claims. After 1987 for pollution and 1992 for asbestos, most liability policies contained industry-standard absolute exclusions of such claims. In earlier years, various exclusions were also applied, but the wording of those exclusions was less strict and subsequent court rulings have reduced their effectiveness.

        OneBeacon also incurred A&E losses via its participation in industry pools and associations. The most significant of these pools was Excess Casualty Reinsurance Association ("ECRA"), which provided excess liability reinsurance to U.S. insurers from 1950 until the early 1980s. ECRA incurred significant liabilities for A&E, of which OneBeacon bears approximately a 4.7% share, or $65 million at December 31, 2004 (compared to $66 million at December 31, 2003), which is fully reflected in OneBeacon's loss and LAE reserves.

        More recently, since the 1990s, OneBeacon has experienced an influx of claims from commercial insureds, including many non-Fortune 500-sized accounts written during the 1970s and 1980s, who are named as defendants in asbestos lawsuits. As a number of large well-known manufacturers of asbestos

68



and asbestos-containing products have gone into bankruptcy, plaintiffs have sought recoveries from peripheral defendants, such as installers, transporters or sellers of such products, or from owners of premises on which the plaintiffs' exposure to asbestos allegedly occurred. At December 31, 2004, 664 policyholders had asbestos-related claims against OneBeacon. In 2004, 112 new insureds with such peripheral involvement presented asbestos claims under prior OneBeacon policies.

        Historically, most asbestos claims have been asserted as product liability claims. Recently, insureds who have exhausted the available products liability limits of their insurance policies have sought payment for asbestos claims under the premises and operations coverage of their liability policies. It is more difficult for plaintiffs to establish losses as stemming from premises and operations exposures, which requires proof of the defendant's negligence, rather than products liability under which strict legal liability applies. Hence, there are fewer of such claims and there is a great deal of variation in damages awarded for the actual injuries. Additionally, several accounts that seek such coverage find that previously paid losses exhausted the aggregate limits under their policies. In these situations there is no coverage for these claims. There are currently 148 active claims against OneBeacon without product liability coverage asserting operations or premises coverage.

        Immediately prior to White Mountains' acquisition of OneBeacon, OneBeacon purchased a reinsurance contract with NICO under which OneBeacon is entitled to recover from NICO up to $2.5 billion in the future for asbestos claims arising from business written by OneBeacon in 1992 and prior, environmental claims arising from business written by OneBeacon in 1987 and prior, and certain other exposures. Under the terms of the NICO Cover, NICO receives the economic benefit of reinsurance recoverables from certain of OneBeacon's third party reinsurers in existence at the time the NICO Cover was executed ("Third Party Recoverables"). As a result, the Third Party Recoverables serve to protect the $2.5 billion limit of NICO coverage for the benefit of OneBeacon. Any amounts uncollectible from third party reinsurers due to dispute or the reinsurers' financial inability to pay are covered by NICO under its agreement with OneBeacon. Third Party Recoverables are typically for the amount of loss in excess of a stated level each year. Of claim payments in the past 11 years, approximately 63% of asbestos losses and 39% of environmental losses have been recovered under the historical third party reinsurance.

        OneBeacon estimates that on an incurred basis it has exhausted approximately $1.7 billion of the coverage provided by NICO at December 31, 2004. At December 31, 2004, $14.3 million of the $1.7 billion of exhausted coverage from NICO related to uncollectible Third Party Recoverables. Net losses paid totaled approximately $682 million as of December 31, 2004, with $95 million paid in 2004. Asbestos payments during 2004 reflect payments resulting from intensified efforts by claimants to resolve asbestos claims prior to enactment of potential Federal asbestos legislation. To the extent that OneBeacon's estimate of ultimate A&E losses as well as the estimate and collectibility of Third Party Recoverables differs from actual experience, the remaining protection under the NICO Cover may be more or less than the approximate $757 million that OneBeacon estimates remained at December 31, 2004.

        For purposes of determining available reinsurance, product liability asbestos claims typically are aggregated as a single loss within each policy period. As a result, losses often exceed the retention level under the reinsurance agreement and reinsurance recoveries are obtained. However, for claims being asserted under premises and operations coverage, the losses are generally not aggregated for purposes of determining reinsurance recoveries, so OneBeacon expects that in the future a smaller percentage of these losses will be covered as Third Party Recoverables than has been true historically of products liability asbestos losses.

        OneBeacon's reserves for A&E losses, net of Third Party Recoverables but prior to NICO recoveries, are $1.0 billion at December 31, 2004. An industry benchmark of reserve adequacy is the "survival ratio", computed as a company's reserves divided by its historical average yearly loss

69



payments. This ratio indicates approximately how many more years of payments the reserves can support, assuming future yearly payments are equal to historical levels. OneBeacon's survival ratio was approximately 21.0 at December 31, 2004, which was computed as the ratio of A&E reserves, net of Third Party Recoverables, of $1.0 billion plus the remaining unused portion of the NICO Cover of $757 million, to the average loss payments in the past three years. The average loss payments used to calculate OneBeacon's survival ratio were net of a large commutation ($64 million) in 2003 with a Third Party Reinsurer. White Mountains believes that as a result of the NICO Cover and its historical third party reinsurance programs, OneBeacon should not experience material financial loss from old A&E exposures under current coverage interpretations and that its survival ratio compares favorably to industry survival ratios.

        OneBeacon's reserves for A&E losses at December 31, 2004 represent management's best estimate of its ultimate liability based on information currently available. OneBeacon believes the NICO Cover will be adequate to cover all of its A&E obligations. However, as case law expands, medical and clean-up costs increase and industry settlement practices change, OneBeacon may be subject to asbestos and environmental losses beyond currently estimated amounts. Therefore, OneBeacon cannot guarantee that its A&E loss reserves, plus the remaining coverage under the NICO Cover, will be sufficient to cover additional liability arising from any such unfavorable developments. See Note 3 to the financial statements for more information regarding White Mountains' A&E reserves.

        OneBeacon's A&E claim activity for the last two years is illustrated in the table below.

        For OneBeacon, the range of reserve estimates at December 31, 2004 was evaluated to consider the strengths and weaknesses of the actuarial methods applied against OneBeacon's historical claims experience data. The following table shows the recorded reserves and the high and low ends of OneBeacon's range of reasonable loss reserve estimates at December 31, 2004. The high and low ends of OneBeacon's range of reserve estimates in the table below are based on the results of various actuarial methods described above. The recorded reserve for each line is the result of the actuarial method that management believes to be most appropriate based on known facts and trends.

        The probability that ultimate losses will fall outside of the ranges of estimates by line of business is higher for each line of business individually than it is for the sum of the estimates for all lines taken together due to the effects of diversification. Although management believes OneBeacon's reserves are reasonably stated, ultimate losses may deviate, perhaps materially, from the recorded reserve amounts and could be above the high end of the range of actuarial projections.

        The recorded reserves represent management's best estimate of unpaid loss and LAE by line of business. In its selection of recorded reserves, management has generally given greater weight to adjusted paid loss development methods, which are not dependent on the consistency of case reserving practices, rather than methods that rely on incurred losses, because of the increased adequacy of case reserving by OneBeacon's claim staff in the recent past. For multiple peril this resulted in OneBeacon recording reserves nearer the low end of the range. For some types of claims, such as workers compensation and construction defect, management also considered special purpose forecasting models that its claims and actuarial staff have created that consider the unique loss development characteristics of these types of claims. For personal automobile liability, homeowners and "other" (principally shorter

71



tailed lines of business such as ocean and inland marine insurance) recorded reserves remain rather high in the respective ranges, as management's selections reflect a conservative approach to recognition of recent favorable development experienced in our ongoing businesses.

White Mountains Re

        White Mountains Re has a specialized unit that handles claims emanating from A&E exposures. The issues presented by these types of claims require specialization, expertise and an awareness of the various trends and jurisdictional developments.

        White Mountains Re's A&E exposure is primarily from reinsurance contracts written between 1974 through 1985 by predecessor companies (MONY Reinsurance and Christiania General). The exposures are predominately higher layer excess of loss treaty and facultative coverages with relatively low limits exposed for each claim. Net incurred loss activity for asbestos and environmental in the last two years was as follows:

Net incurred loss and LAE activity

  2003
 
  ($ in millions)

Asbestos   $ 2.6   $ 32.0
Environmental     .1     3.7
   
 
Total   $ 2.7   $ 35.7
   
 

        In recent years, most of White Mountains Re's reported activity in the asbestos area has related to (1) higher layer excess policies that are being reached by larger target defendants, (2) new notices for smaller regional defendants that are now exposed because of the larger defendant bankruptcies, and (3) new notices on "premises" and "non-products" cases, where coverage is being sought by insureds against the non-aggregating portion of the underlying policy. WM Re expects to see a smaller percentage of these losses exceed the retention level under reinsurance agreements.

        Approximately $25.0 million of White Mountains Re's 2003 loss development for asbestos exposures was a bulk increase in IBNR resulting from the completion of a detailed A&E market share study. This study compared White Mountains Re's share of industry paid losses to estimated industry carried reserves.

        White Mountains Re sets up claim files for each reported claim by each cedent for each individual insured. In many instances, a single claim notification from a cedent could involve several years and layers of coverage resulting in a file being set up for each involvement. Precautionary claim notices are submitted by the ceding companies in order to preserve their right to pursue coverage under the reinsurance contract. Such notices do not contain an incurred loss amount to White Mountains Re, accordingly, an open claim file is not established. As of December 31, 2004, White Mountains Re had approximately 1,368 open claim files for asbestos and 786 open claim files for environmental exposures.

        The costs associated with administering the underlying A&E claims by White Mountains Re's clients tend to be higher than non-A&E claims due to generally higher legal costs incurred by ceding companies in connection with A&E claims ceded to White Mountains Re under the reinsurance contracts.

        White Mountains Re establishes loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for reinsured events that have already occurred. The estimation of net reinsurance loss and LAE reserves is subject to the same risk as the estimation of insurance loss and LAE reserves. In addition to those risk factors which give rise to inherent uncertainties in establishing insurance loss and LAE reserves, the inherent uncertainties of estimating such reserves are even greater for the reinsurer, due primarily to: (1) the claim-tail for reinsurers being further extended because claims are first reported to the ceding company and then through one or more intermediary insurers or reinsurers, (2) the diversity of loss development patterns among different types of reinsurance treaties or facultative contracts, (3) the necessary reliance on the ceding companies for information regarding reported claims and (4) the differing reserving practices among ceding companies.

        As with insurance reserves, the process of estimating reinsurance reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain. Based on the above, such uncertainty may be larger relative to the reserve for a reinsurer compared to an insurance company, and may take a longer time to emerge.

        In order to reduce the potential uncertainty of loss reserve estimation, White Mountains Re obtains information from numerous sources to assist in the process. White Mountains Re's pricing actuaries devote considerable effort to understanding and analyzing a ceding company's operations and loss history during the underwriting of the business, using a combination of ceding company and industry statistics. Such statistics normally include historical premium and loss data by class of business, individual claim information for larger claims, distributions of insurance limits provided, loss reporting

73



and payment patterns, and rate change history. This analysis is used to project expected loss ratios for each treaty during the upcoming contract period. These expected ultimate loss ratios are aggregated across all treaties and are input directly into the loss reserving process to generate the expected loss ratios that are used to estimate IBNR.

        Upon notification of a loss from a ceding company, White Mountains Re establishes case reserves, including LAE reserves, based upon White Mountains Re's share of the amount of reserves established by the ceding company and our independent evaluation of the loss. In cases where available information indicates that reserves established by the ceding company are inadequate, White Mountains Re establishes case reserves or IBNR in excess of its share of the reserves established by the ceding company. In addition, specific claim information reported by ceding companies or obtained through claim audits can alert us to emerging trends such as changing legal interpretations of coverage and liability, claims from unexpected sources or classes of business, and significant changes in the frequency or severity of individual claims. Such information is often used to supplement estimates of IBNR.

        As mentioned above, there can be a considerable time lag from the time a claim is reported to a ceding company to the time it is reported to the reinsurer. The lag can be several years in some cases. This lag can be due to a number of reasons, including the time it takes to investigate a claim, delays associated with the litigation process, the deterioration in a claimant's physical condition many years after an accident occurs, etc. In its loss reserving process, White Mountains Re assumes that such lags are predictable, on average, over time and therefore the lags are contemplated in the loss reporting patterns used in its actuarial methods. This means that, as a reinsurer, White Mountains Re must rely on such actuarial estimates for a longer period of time after reserves are first estimated than does a primary insurance company.

        Backlogs in the recording of assumed reinsurance can also complicate the accuracy of loss reserve estimation. As of December 31, 2004, there were no significant backlogs related to the processing of assumed reinsurance information at White Mountains Re.

        White Mountains Re relies heavily on information reported by ceding companies, as discussed above. In order to determine the accuracy and completeness of such information, White Mountains Re's U.S. underwriters, actuaries, and claims personnel perform regular audits of Folksamerica's ceding companies. While regular ceding company audits are not customary outside the United States, Sirius International's staff regularly reviews information from ceding companies for unusual or unexpected results. Any material findings are discussed with the ceding companies. White Mountains Re sometimes encounters situations where we determine that a claim presentation from a ceding company is not in accordance with contract terms. In these situations, White Mountains Re attempts to resolve the dispute directly with the ceding company. Most situations are resolved amicably and without the need for litigation or arbitration. However, in the infrequent situations where a resolution is not possible, White Mountains Re will vigorously defend our position in such disputes.

        Although loss and LAE reserves are initially determined based on underwriting and pricing analysis, White Mountains Re constantly tests the accuracy of reserves using a variety of generally accepted actuarial methods, including historical incurred and paid loss development methods. If actual loss activity differs substantially from expectations based on historical information, an adjustment to loss reserves may be warranted. As time passes, loss reserve estimates for a given accident year will rely more on actual loss activity and historical patterns than on initial assumptions based on pricing indications.

        White Mountains Re also obtain reinsurance whereby another reinsurer contractually agrees to indemnify White Mountains Re for all or a portion of the reinsurance risks underwritten by White Mountains Re. Such arrangements, where one reinsurer provides reinsurance to another reinsurer, are usually referred to as "retrocessional reinsurance" arrangements. White Mountains Re establishes estimates of amounts recoverable from retrocessional reinsurance in a manner consistent with the loss

74



and LAE liability associated with reinsurance contracts offered to its customers (the "ceding companies"), net of an allowance for uncollectible amounts, if any. Net reinsurance loss reserves represent loss and LAE reserves reduced by retrocessional reinsurance recoverable on unpaid losses.

        White Mountains Re's net loss and LAE reserves by class of business at December 31, 2004 and 2003 were as follows:

        White Mountains Re establishes loss reserves based on a single point estimate, which is management's best estimate of ultimate losses and loss expenses. This "best estimate" is derived from a combination of methods as described above. Once a point estimate is established, White Mountains Re's actuaries estimate loss reserve ranges to measure the sensitivity of the actuarial assumptions used to set the point estimates. These ranges are calculated using similar methods to the point estimate calculation, but with different expected loss ratio and loss reporting pattern assumptions. For the low estimate, more optimistic loss ratios and faster reporting patterns are assumed, while the high estimate uses more conservative loss ratios and slower reporting patterns. These variable assumptions are derived from historical variations in loss ratios and reporting patterns by class and type of business. Due to the inherent difficulties in estimating ultimate A&E exposures, White Mountains Re does not estimate ranges for these reserves. The growth in reserves from 2003 to 2004 was driven by acquisitions made during 2004.

        The following table illustrates White Mountains Re's recorded net loss and LAE reserves and high and low estimates for those classes of business for which a range is calculated, at December 31, 2004.

        The probability that ultimate losses will fall outside of the ranges of estimates by class of business is higher for each class of business individually than it is for the sum of the estimates for all classes taken together due to the effects of diversification. Although management believes reserves for White Mountains Re are reasonably stated, ultimate losses may deviate, perhaps materially, from the recorded reserve amounts and could be above the high end of the range of actuarial projections.


2.    White Mountains Re Reinsurance Estimates

        There is a time lag from the point when premium and related commission and expense activity is recorded by a ceding company to the point when such information is reported by the ceding company, through its reinsurance intermediary, to White Mountains Re. This time lag can vary from one to

75



several contractual reporting periods (i.e. quarterly/monthly). This lag is common in the broker market reinsurance business.

        As a result of this time lag in reporting, White Mountains Re estimates a portion of its written premium and related commissions and expenses. Given the nature of White Mountains Re's business, estimated premium balances, net of related commissions and expenses, comprise a large portion of total premium balances receivable. The estimation process begins by identifying which major accounts have not reported activity at the most recent period end. In general, premium estimates for excess of loss business are based on minimum deposit information included in the contractual terms. For proportional business, White Mountains Re's estimates are derived based on a variety of factors and assumptions, including: prior reporting from the broker or ceding company, historical reporting patterns, expected premium volume based on contractual terms or ceding company reports and other correspondence and communication with underwriters, brokers, intermediaries and ceding companies. Once premium estimates are determined, related commission and expense estimates are derived using contractual terms.

        White Mountains Re closely monitors its estimation process on a quarterly basis and adjusts its estimates as more information and actual amounts become known. There is no assurance that the amounts estimated by White Mountains Re will not deviate from the amounts reported by the ceding company or reinsurance broker. Any such deviations are reflected in the results of operations when they become known.

        The net amounts recorded in reinsurance balances receivable may not yet be due from the ceding company at the time of the estimate since actual reporting from the ceding company has not yet occurred. Therefore, based on the process described above, White Mountains Re believes all of its estimated balances are collectible, and as such no allowance has been recorded.


3.    Reinsurance Transactions

        White Mountains' insurance and reinsurance subsidiaries purchase reinsurance from time to time to protect their businesses from losses due to exposure aggregation, to manage their operating leverage ratios and to limit ultimate losses arising from catastrophic events. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured

76



policies. Amounts related to reinsurance contracts are recorded in accordance with SFAS No. 113, "Accounting and Reporting for Reinsurance of Short-Duration and Long-Duration Contracts" ("SFAS 113").

        The collectibility of reinsurance recoverables is subject to the solvency and willingness to pay of the reinsurer. The Company is selective in choosing its reinsurers, placing reinsurance principally with those reinsurers with a strong financial condition, industry ratings and underwriting ability. Management monitors the financial condition and ratings of its reinsurers on an ongoing basis. See Note 4—Third Party Reinsurance in the accompanying Consolidated Financial Statements for additional information on White Mountains' reinsurance programs.


4.    Pension and Post-Retirement Medical Plans

        White Mountains accounts for its pension plans in accordance with SFAS No. 87, "Employers' Accounting for Pensions" ("SFAS 87") and accounts for its retiree medical plan in accordance with SFAS No. 106, "Employers' Accounting for Postretirement Benefits Other Than Pensions" ("SFAS 106"). SFAS 87 and SFAS 106 require that the cost of pension/retiree medical benefits be accrued over the period during which an employee provides service.

        The majority of OneBeacon's pension and retiree medical plans were curtailed in the fourth quarter of 2002. The OneBeacon Pension Plan no longer adds new participants or increases benefits for existing participants. Non-vested participants already in the plan continue to vest during their employment with OneBeacon. Retirees are also eligible for medical benefits if they meet certain age and service requirements. However, due to the curtailment, the plan no longer accepts new participants. The majority of retiree medical costs are capped at defined dollar amounts, with retirees contributing the remainder.

        The projected benefit obligation as of a particular date represents the actuarial present value of all benefits attributed by the plan's benefit formula to employee service rendered prior to that date. Therefore, future cash payments from pension and retiree medical plans are discounted using a discount rate based on published investment grade, long-term corporate bond yields. Many of the factors which are used to determine a plan's projected benefit obligation as of a particular date and the cost of pension/retiree medical benefits for a particular period are dependent upon future events, such as how long the employee and any survivors live, how many years of service the employee is expected to render and the employee's compensation in the years immediately before retirement or termination. Accordingly, the effects of such future factors are estimated. Further, since the projected benefit obligation and the periodic cost of pension/retiree medical benefits are based on actuarial present values, they are also sensitive to changes in the discount rate used to determine such amounts.

        A hypothetical 1% increase in the discount rate would result in a decrease in pension and retiree medical projected benefit obligations of approximately $63 million. A hypothetical 1% decrease in the discount rate would result in an increase in pension and retiree medical projected benefit obligations of approximately $63 million. The impact of a hypothetical 1% change to the discount rate on periodic cost of pension/retiree medical benefits is not significant.

        Additionally, the rate of return that is assumed on plan assets affects OneBeacon's pension expense during a particular period. Since the retiree medical plan is unfunded, it is not affected by changes in the rate of return assumption. OneBeacon performed an analysis of expected long-term rates of return based on the allocation of its pension plan assets as of both December 31, 2004 and December 31, 2003 to develop expected rates of return for each significant asset class or economic indicator. A range of returns was developed based both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class. Although the expected investment return assumption is long-term in nature, the range of reasonable returns has dropped over the past few years as a consequence of lower inflation and lower bond yields. As a result of the most

77



recent review, for 2004 OneBeacon elected to keep the expected return on its pension assets at 7.0%, as was used in 2003. At December 31, 2004, 36% of plan assets were invested in fixed maturity securities, 45% in equities and the remainder in cash, cash equivalents and convertible securities. A hypothetical 1% increase or decrease in the assumed rate of return would result in a pretax change in OneBeacon's pension expense (or income as the case may be) for 2004 of approximately $4.7 million.

        During 2004, OneBeacon recognized pension expense of $3.3 million, which was comprised of net periodic benefit cost of $.4 million and special termination benefits of $2.9 million. Included in the net periodic benefit cost is $32.2 million of expected return on pension plan assets. OneBeacon contributed $4.2 million to the pension plan in 2004. No unrecognized losses on pension assets were recorded since the Company uses the market value method to value plan assets.


5.    Purchase Accounting

        When White Mountains acquires another company, management must estimate the fair values of the assets and liabilities acquired, as prescribed by SFAS No. 141, "Business Combinations" ("SFAS 141"). Certain assets and liabilities require little judgment to estimate their fair values, particularly those that are quoted on a market exchange, such as publicly-traded investment securities. Other assets and liabilities, however, require a substantial amount of judgment to estimate their fair values. The most significant of these is the estimation required to fair value loss and LAE reserves.

        White Mountains estimates the fair value of loss and LAE reserves obtained in an acquisition following the principles contained within FASB Statement of Financial Accounting Concepts No. 7: "Using Cash Flow Information and Present Value in Accounting Measurements" ("CON 7"). Under CON 7, the fair value of a particular asset or liability essentially contains five elements: (1) an estimate of the future cash flows, (2) expectations about possible variations in the amount or timing of those cash flows; (3) the time value of money, represented by the risk-free rate of interest; (4) the price for bearing the uncertainty inherent in the asset or liability; and (5) other, sometimes unidentifiable, factors including illiquidity and market imperfections.

        White Mountains' actuaries estimate the fair value of loss and LAE reserves obtained in an acquisition by taking the acquired company's recorded reserves and discounting them based on expected reserve payout patterns using the current risk-free rate of interest. Then, White Mountains' actuaries develop additional cash flow scenarios that use different payout and ultimate reserve assumptions deemed to be reasonably possible based upon the inherent uncertainties present in determining the amount and timing of payment of such reserves. In each scenario, the risk-free rate of interest is used to discount future cash flows. These scenarios are put in a statistical model that assigns a probability to each cash flow scenario. White Mountains' actuaries then choose the scenario that best represents the price for bearing the uncertainty inherent within the acquired company's recorded reserves. The "price" for bearing the uncertainty inherent within the acquired company's reserves is measured as the difference between the selected cash flow scenario and the expected cash flow scenario. The scenario selected has typically been between 1.5 and 2 standard deviations from the expected cash flow outcome. The fair value of the acquired company's loss and LAE reserves is determined to be the sum of the expected cash flow scenario (i.e., the acquired company's discounted loss and LAE reserves) and the uncertainty "price".

        The difference between an acquired company's loss and LAE reserves and White Mountains' best estimate of the fair value of such reserves at the acquisition date is amortized ratably over the payout period of the acquired loss and LAE reserves. Historically, the fair value of an acquired company's loss and LAE reserves has been less than the it's recorded reserves at acquisition. Accordingly, the amortization has been and will continue to be recorded as an expense on White Mountains' income statement until fully amortized.

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        White Mountains' consolidated balance sheet includes a substantial amount of assets and liabilities whose fair values are subject to market risk. The term market risk refers to the risk of loss arising from adverse changes in interest rates and other relevant market rates and prices. Due to White Mountains' sizable balances of interest rate sensitive instruments, market risk can have a significant effect on White Mountains' consolidated financial position.


Interest Rate Risk

        Fixed Maturity Portfolio.    In connection with the Company's consolidated insurance and reinsurance subsidiaries, White Mountains invests in interest rate sensitive securities, primarily debt securities. White Mountains' strategy is to purchase fixed maturity investments that are attractively priced in relation to perceived credit risks. White Mountains' fixed maturity investments are held as available for sale in accordance with SFAS No. 115, "Accounting for Certain Investments in Debt and Equity Securities" ("SFAS 115"), whereby these investments are carried at fair value on the balance sheet with net unrealized gains or losses reported net of tax in a separate component of common shareholders' equity. White Mountains generally manages its interest rate risk associated with its portfolio of fixed maturity investments by monitoring the average duration of the portfolio, which allows White Mountains to achieve an adequate yield without subjecting the portfolio to an unreasonable level of interest rate risk. White Mountains' fixed maturity portfolio is comprised of primarily investment grade corporate securities, U.S. government and agency securities, municipal obligations and mortgage-backed securities (e.g., those receiving an investment grade rating from S&P or Moody's).

        Increases and decreases in prevailing interest rates generally translate into decreases and increases in fair values of fixed maturity investments, respectively. Additionally, fair values of interest rate sensitive instruments may be affected by the credit worthiness of the issuer, prepayment options, relative values of alternative investments, the liquidity of the instrument and other general market conditions.

        The table below summarizes the estimated effects of hypothetical increases and decreases in market interest rates on White Mountains' fixed maturity portfolio and pension plan.

        Long-term obligations.    As of December 31, 2004, White Mountains' interest and dividend bearing long-term obligations consisted primarily of the Senior Notes and the Berkshire and Zenith Preferred Stock obligations, which have fixed interest and dividend rates. As a result, White Mountains exposure to interest rate risk resulting from variable interest rate obligations is insignificant.

        The Senior Notes were issued in 2003 and mature on May 15, 2013. At December 31, 2004, the fair value of White Mountains' Senior Notes was approximately $714 million, which compared to a carrying value of $698 million.

80



        The Berkshire and Zenith Preferred Stock obligations were issued in 2001 and mature on May 31, 2008 and May 31, 2011, respectively. At the Company's option, the Zenith Preferred Stock may be redeemed on June 30, 2007. At December 31, 2004, the fair values of the Berkshire and Zenith Preferred Stock were approximately $341 million and $23 million, respectively, which compared to carrying values of $192 million and $20 million, respectively.

        The fair values of these obligations were estimated by discounting future cash flows using current market rates for similar obligations or using quoted market prices.


Equity Price Risk

        The carrying values of White Mountains' common equity securities and its other investments are based on quoted market prices or management's estimates of fair value (which is based, in part, on quoted market prices) as of the balance sheet date. Market prices of common equity securities, in general, are subject to fluctuations which could cause the amount to be realized upon sale or exercise of the instruments to differ significantly from the current reported value. The fluctuations may result from perceived changes in the underlying economic characteristics of the investee, the relative price of alternative investments, general market conditions and supply and demand imbalances for a particular security.


Foreign Currency Exchange Rates

        White Mountains' foreign assets and liabilities are valued using period-end exchange rates and its foreign revenues and expenses are valued using average exchange rates. Foreign currency exchange rate risk is the risk that White Mountains will incur losses on a U.S. Dollar basis due to adverse changes in foreign currency exchange rates.

        At December 31, 2004, OneBeacon held approximately $384 million in bonds denominated in foreign currencies, mostly those denominated in British Pounds. Assuming a hypothetical 10% increase or decrease in the rate of exchange from the British Pound to the U.S. Dollar as of December 31, 2004, the carrying value of OneBeacon's foreign currency-denominated bond portfolio would have respectively decreased or increased by approximately $37 million.

        As a result of the Sirius Acquisition during 2004, White Mountains has a higher concentration of assets, liabilities, revenues and expenses denominated in foreign currencies than in prior periods. The functional currency of Sirius International is the Swedish Krona. Assuming a hypothetical 10% increase or decrease in the rate of exchange from the Swedish Krona to the U.S. Dollar as of December 31, 2004, the carrying value of White Mountains' net assets denominated in Swedish Kronor would have respectively decreased or increased by approximately $40 million.

Based on that evaluation, the PEO and

81

        The PEO and the PFO of White Mountains have evaluated the effectiveness of its internal control over financial reporting as of December 31, 2004.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. Summary of Significant Accounting Policies

Basis of presentation

        The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries and have been prepared in accordance with GAAP in the United States. Previously defined terms used within these financial statements have the same meaning as they have elsewhere within this report. The Company is a Bermuda limited liability company with its headquarters located at The Bank of Butterfield Building, 42 Reid Street, 6th Floor, Hamilton HM 12, Bermuda. The Company's principal executive office is located at 80 South Main Street, Hanover, New Hampshire 03755-2053 and its registered office is located at Clarendon House, 2 Church Street, Hamilton, Bermuda HM 11.

        The Company's reportable segments are OneBeacon, White Mountains Re, Esurance and Other Operations.

        The OneBeacon family of companies are U.S.-based property and casualty insurance writers, which were acquired by White Mountains from Aviva plc ("Aviva", formerly CGNU plc) on June 1, 2001 (the "OneBeacon Acquisition").

        White Mountains' reinsurance operations are conducted primarily through its recently formed global reinsurance organization ("White Mountains Re"), which oversees the operations of Folksamerica, Sirius, and WMU, as described below.

        Folksamerica Reinsurance Company, together with its parent, Folksamerica Holding Company, ("Folksamerica") became a wholly-owned subsidiary of White Mountains in 1998. In connection with the OneBeacon Acquisition, Folksamerica was contributed to OneBeacon. On November 30, 2004, White Mountains completed a significant corporate reorganization and, as part of the reorganization, ownership of Folksamerica was transferred to White Mountains Re.

        On April 16, 2004, White Mountains acquired Sirius Insurance Holding Sweden AB and its subsidiaries ("Sirius"), a group of international insurers and reinsurers that focuses mainly on property and other short-tailed lines, from ABB Ltd. (See Note 2). Subsequent to White Mountains' acquisition of Sirius, Fund American Reinsurance Company Ltd. ("Fund American Re") was sold to Sirius by the Company. Accordingly, the results of Fund American Re are included in Sirius' results throughout this report. White Mountains' reinsurance operations also include its wholly owned subsidiaries, White Mountains Underwriting Limited (domiciled in Ireland) and White Mountains Underwriting (Bermuda) Limited (collectively, "WMU"). WMU is an reinsurance advisory company specializing in international property and marine excess reinsurance.

        Esurance has been a unit of White Mountains since October 2000. Esurance markets personal auto insurance directly to customers and through select online agents.

        White Mountains' Other Operations consists of the Company and its intermediate holding companies, as well as the International American Group, Inc. (the "International American Group"). The International American Group, which was acquired by White Mountains in 1999, consists of American Centennial Insurance Company ("American Centennial") and British Insurance Company of Cayman ("British Insurance Company") and, prior to its sale in January 2004, also included Peninsula Insurance Company ("Peninsula").

        White Mountains has completed numerous significant transactions during the periods presented which have affected the comparability of the financial statement information presented herein. White Mountains' consolidated statements of income and comprehensive income include the results of acquired businesses beginning as of the date each respective acquisition was completed. Net changes in

F-5



assets and liabilities reported in the consolidated statements of cash flows exclude those assets and liabilities acquired or sold during the periods presented.

        All significant intercompany transactions have been eliminated in consolidation. The financial statements include all adjustments considered necessary by management to fairly present the Company's financial position, its results of operations and its cash flows.

        The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Certain amounts in the prior period financial statements have been reclassified to conform with the current presentation.

Investment securities

        White Mountains' portfolio of fixed maturity investments and common equity securities are classified as available for sale and are reported at fair value as of the balance sheet date as determined by quoted market values. Other investments principally include investments in limited partnership interests which are recorded using the equity method of accounting. Net unrealized investment gains and losses, after-tax, associated with such investments are reported as a net amount as a separate component of shareholders' equity. Changes in net unrealized investment gains and losses, after-tax, are reported as a component of other comprehensive income. Investment securities are regularly reviewed for impairment based on criteria that include the extent to which cost exceeds market value, the duration of the market decline, the financial health of and specific prospects for the issuer and the ability and intent to hold the investment to maturity. Investment losses that are other than temporary are recognized in earnings. Realized gains and losses resulting from sales of investment securities are accounted for using the weighted average method.

        Premiums and discounts on fixed maturity investments are accreted to income over the anticipated life of the investment.

        Short-term investments consist of money market funds, certificates of deposit and other securities which mature or become available for use within one year. Short-term investments are carried at amortized cost, which approximated fair value as of December 31, 2004 and 2003.

        White Mountains participates in a securities lending program whereby certain of its fixed maturity investments are loaned to other institutions for short periods of time through a lending agent. White Mountains maintains control over the securities it lends, retains the earnings and cash flows associated with the loaned securities and receives a fee from the borrower for the temporary use of the asset. Collateral, in the form of cash and United States government securities, is required at a rate of 102% of the fair value of the loaned securities and is monitored and maintained by the lending agent. The fair value of the securities lending collateral is recorded as both an asset and liability on the balance sheet. An indemnification agreement with the lending agent protects White Mountains in the event a borrower becomes insolvent or fails to return any of the securities on loan.

        The Company does not use derivatives for hedging, but does own convertible bonds with embedded derivatives. In accordance with SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities", the Company bifurcates all equity option derivatives that are embedded in its convertible bonds. The original host instruments are reported, at fair value, in fixed maturity investments and the embedded derivatives are reported, at fair value, in other investments. Because these derivatives do not qualify as hedging instruments, changes in fair values of derivatives are included in realized gains and losses. The fair value of derivatives included in other investments was $33.9 million at December 31, 2004 and realized gains (losses) on derivatives was $7.3 million for the period ending December 31, 2004.

F-6



Cash

        Cash includes amounts on hand and demand deposits with banks and other financial institutions. Amounts presented in the statement of cash flows are shown net of balances acquired and sold in the purchase or sale of the Company's consolidated subsidiaries.

Insurance and reinsurance operations

        White Mountains accounts for insurance and reinsurance policies that it writes in accordance with SFAS No. 60, "Accounting and Reporting by Insurance Enterprises" ("SFAS 60"). Premiums written are recognized as revenues and are earned ratably over the term of the related policy or reinsurance treaty. Unearned premiums represent the portion of premiums written that are applicable to future insurance or reinsurance coverage provided by policies or treaties in force. AutoOne Insurance, which acts as a limited assigned distribution ("LAD") servicing carrier, enters into contractual arrangements with insurance companies to assume private passenger automobile assigned risk exposures in the state of New York. AutoOne Insurance receives LAD servicing fees for assuming these risks. LAD servicing fees are typically a percentage of the total premiums that AutoOne Insurance must write to fulfill the obligation of the transferor company. LAD servicing carriers may choose to write certain policies voluntarily by taking risks out of the NYAIP. These policies generate takeout credits which can be "sold" for fees to the transferor company ("takeout fees"). These fees are also typically a percentage of the transferor company's NYAIP premium assignments. AutoOne Insurance's LAD servicing and takeout fees are recorded as written premium when billed and are earned ratably over the term of the related policy to which the fee relates.

        Deferred acquisition costs represent commissions, premium taxes, brokerage expenses and other costs which are directly attributable to and vary with the production of new business. These costs are deferred and amortized over the applicable premium recognition period as insurance and reinsurance acquisition expenses. Deferred acquisition costs are limited to the amount expected to be recovered from future earned premiums and anticipated investment income. This limitation is referred to as a premium deficiency. A premium deficiency is recognized if the sum of expected loss and LAE, expected dividends to policyholders, unamortized acquisition costs, and maintenance costs exceeds related unearned premiums. A premium deficiency is recognized by charging any unamortized acquisition costs to expense to the extent required in order to eliminate the deficiency. If the premium deficiency exceeds unamortized acquisition costs then a liability is accrued for the excess deficiency.

        Losses and LAE are charged against income as incurred. Unpaid insurance losses and LAE are based on estimates (generally determined by claims adjusters, legal counsel and actuarial staff) of the ultimate costs of settling claims, including the effects of inflation and other societal and economic factors. Unpaid reinsurance losses and LAE are based primarily on reports received from ceding companies and actuarial projections. Unpaid loss and LAE reserves represent management's best estimate of ultimate losses and LAE, net of estimated salvage and subrogation recoveries, if applicable. Such estimates are regularly reviewed and updated and any adjustments resulting therefrom are reflected in current operations. The process of estimating loss and LAE involves a considerable degree of judgment by management and the ultimate amount of expense to be incurred could be considerably greater than or less than the amounts currently reflected in the financial statements.

        OneBeacon discounts certain of its long-term workers compensation loss and LAE reserves when such liabilities constitute unpaid but settled claims under which the payment pattern and ultimate costs are fixed and determinable on an individual claim basis. OneBeacon discounts these reserves using an average discount rate which is determined based on the facts and circumstances applicable at the time the claims are settled (4.7% at December 31, 2004 and 2003). As of December 31, 2004 and 2003, the discount on OneBeacon's workers compensation loss and LAE reserves amounted to $259.4 million and $294.5 million, respectively.

F-7



        In connection with purchase accounting for the OneBeacon Acquisition, White Mountains was required to adjust to fair value OneBeacon's loss and LAE reserves and the related reinsurance recoverables by $646.9 million and $346.9 million, respectively, on OneBeacon's acquired balance sheet as of June 1, 2001. This net reduction to loss and LAE reserves of $300.0 million is being accreted through an income statement charge ratably over the period that the claims to which such reserves relate are expected to be settled. See Note 3.

        In connection with purchase accounting for the Sirius Acquisition, White Mountains was required to adjust to fair value the loss and LAE reserves on Sirius' acquired balance sheet by $58.1 million. This fair value adjustment is being recognized through an income statement charge ratably with and over the period the claims are settled. See Note 3.

        White Mountains' insurance and reinsurance subsidiaries enter into ceded reinsurance contracts from time to time to protect their businesses from losses due to concentration of risk, to manage their operating leverage ratios and to limit losses arising from catastrophic events. The majority of such reinsurance contracts are executed through excess of loss treaties and catastrophe contracts under which the reinsurer indemnifies for a specified part or all of certain types of losses over stipulated amounts arising from any one occurrence or event. White Mountains has also entered into quota share treaties with reinsurers under which all risks meeting prescribed criteria are covered on a pro-rata basis. The amount of each risk ceded by White Mountains is subject to maximum limits which vary by line of business and type of coverage. Amounts related to reinsurance contracts are recorded in accordance with SFAS 113 and Emerging Issues Task Force Topic No. D-54, as applicable.

        Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured policies. The collectibility of reinsurance recoverables is subject to the solvency of the reinsurers. White Mountains is selective in regard to its reinsurers, principally placing reinsurance with those reinsurers with a strong financial condition, industry ratings and underwriting ability. Management monitors the financial condition and ratings of its reinsurers on an ongoing basis.

        Reinsurance premiums, commissions, expense reimbursements and reserves related to reinsured business are accounted for on a basis consistent with those used in accounting for the original policies issued and the terms of the reinsurance contracts. Premiums ceded to other companies are reported as a reduction of premiums written. Expense allowances received in connection with reinsurance ceded have been accounted for as a reduction of the related policy acquisition costs and are deferred and amortized accordingly. Funds held by ceding companies represent amounts due to White Mountains in connection with certain assumed reinsurance agreements in which the ceding company retains a portion of the premium to provide security against future loss payments. The funds held by ceding companies are generally invested by the ceding company and a contractually agreed amount is credited to the Company and recognized as investment income. Funds held under reinsurance treaties represent contractual payments due to the reinsurer that White Mountains has retained to secure obligations of the reinsurer. Such amounts are recorded as liabilities in the consolidated financial statements.

Accounting for Mandatory Shared Market Mechanisms

        As a condition to its licenses to do business in certain states, White Mountains' insurance operations must participate in various mandatory shared market mechanisms commonly referred to as "residual" or "involuntary" markets. These markets generally consist of risks considered to be undesirable from a standard or routine underwriting perspective. Each state dictates the levels of insurance coverage that is mandatorily assigned to participating insurers within these markets. The total amount of such business an insurer must accept in a particular state is generally based on that insurer's market share of voluntary business written within that state. In certain cases, White Mountains is obligated to write business from shared market mechanisms at a future date based on its historical market share of all voluntary policies written within that state. Involuntary business generated from

F-8



mandatory shared market mechanisms is accounted for in accordance with SFAS 60 or as assumed reinsurance under SFAS 113, "Accounting and Reporting for Reinsurance of Short-Duration and Long-Duration Contracts" (hereafter referred to as structured contracts) depending upon the structure of the mechanism.

        OneBeacon's market assignments are typically required to be written in the current period, however, in certain cases OneBeacon is required to accept policy assignments at a future date. OneBeacon's residual market assignments to be written in the future primarily relate to private passenger automobile assigned risk exposures within the State of New York where several of OneBeacon's insurance subsidiaries write voluntary automobile insurance. The share of involuntary written premium for policies assigned by the NYAIP to a particular insurer in a given year is based on the proportion of the total voluntary writings in New York two years prior. Anticipated losses associated with future market assignments are recognized in accordance with SFAS No. 5, "Accounting for Contingencies", when the amount of such anticipated losses is determined to be probable and can be reasonably estimated.

Accounting for Insurance-Related Assessments

        Under existing guaranty fund laws in all states, insurers licensed to do business in those states can be assessed for certain obligations of insolvent insurance companies to policyholders and claimants. In accordance with Statement of Position 97-3, "Accounting by Insurance and Other Enterprises for Insurance-Related Assessments" ("SOP 97-3"), White Mountains' insurance subsidiaries record guaranty fund assessments when such assessments are billed by the respective guaranty funds. In addition, each insurance subsidiary's policy is to accrue for any significant insolvencies when the loss is probable and the assessment amount can be reasonably estimated.

Reserves for Structured Contracts

        The reserve for structured contracts represents deposit liabilities for reinsurance contracts that do not satisfy the conditions for reinsurance accounting established in SFAS 113.

        For insurance and reinsurance contracts that transfer only significant timing risk or that transfer neither significant timing risk nor significant underwriting risk, the amount of the deposit asset or liability is adjusted at the balance sheet date by calculating the effective yield on the deposit to reflect actual payments to date and expected future payments. Changes in the carrying amounts are reported as a component of net investment income. Fees related to these contracts are recorded as investment income and are earned using the effective yield method or evenly over the life of the contract dependent upon contract terms.

Deferred Software Costs

        White Mountains capitalizes costs related to computer software developed for internal use during the application development stage of software development projects in accordance with Statement of Position 98-1, "Accounting for the Costs of Computer Software Developed or Obtained for Internal Use". These costs generally consist of certain external, payroll and payroll-related costs. White Mountains begins amortization of these costs once the project is completed and ready for its intended use. Amortization is on a straight-line basis and over a useful life of three to five years. At December 31, 2004 and 2003, White Mountains had deferred software costs of $56.1 million and $51.7 million, respectively.

F-9



Federal and foreign income taxes

        The majority of White Mountains' subsidiaries file consolidated tax returns in the United States. Income earned or losses generated by companies outside the United States are generally subject to an overall effective tax rate lower than that imposed by the United States.

        Deferred tax assets and liabilities are recorded when a difference between an asset or liability's financial statement value and its tax reporting value exists, and for other temporary differences as defined by SFAS No. 109, "Accounting for Income Taxes". The deferred tax asset or liability is recorded based on tax rates expected to be in effect when the difference reverses.

Foreign currency exchange

        The U.S. dollar is the functional currency for all of the Company's businesses except for the foreign reinsurance operations of Folksamerica, Sirius and WMU, foreign investment securities and certain other smaller international activities. The national currencies of the subsidiaries are their functional currencies since their business is primarily transacted in such local currency. Assets and liabilities recorded in these foreign currencies are translated into U.S. dollars at exchange rates in effect at the balance sheet date, and revenues and expenses are converted using the average exchange rates for the period. Net foreign exchange gains and losses arising from the translation are generally reported in shareholders' equity, in accumulated other comprehensive income or loss, net of tax.

        Assets and liabilities relating to foreign operations are translated into the functional currency using current exchange rates; revenues and expenses are translated into the functional currency using the exchange rate of the transaction day. The resulting exchange gains and losses are reported as a component of net income in the period in which they arise.    As of December 31, 2004 and 2003, White Mountains had an after-tax unrealized foreign currency translation gain (loss) of $48.5 million and ($.3) million, respectively, recorded on its consolidated balance sheet. For the years ended December 31, 2004, 2003 and 2002, White Mountains' foreign currency gains and losses reported on its consolidated income statements were insignificant for all periods presented. The following rates of exchange for the U.S. dollar have been used for the most significant operations:

The diluted earnings per share numerators for certain periods presented include an adjustment to White Mountains' equity in earnings related to its investment in the common shares of Montpelier, which is reflective of dilution in Montpelier's earnings brought about by outstanding warrants and options to acquire common shares of Montpelier that are in-the-money. As of March 31, 2004, White Mountains changed its method of accounting for this investment from equity accounting to

F-11


(2)
The diluted earnings per share denominators for the years ended December 31, 2004, 2003 and 2002 include the dilutive effects of average outstanding warrants to acquire 852,678, 1,724,200 and 1,724,200 Common Shares, respectively, at a strike price of $173.99 per Common Share. The warrants were fully exercised on June 29, 2004. The diluted earnings per share denominators presented exclude the anti-dilutive effects of outstanding Options and unearned restricted Common Shares outstanding that are being fully expensed over the vesting period.

Recently Adopted Changes in Accounting Principles

Variable Interest Entities

        In January 2003, the Financial Accounting Standards Board ("FASB") issued Interpretation No. 46, "Consolidation of Variable Interest Entities" ("FIN 46"), which addresses consolidation issues surrounding special purpose entities and certain other entities, collectively termed variable interest entities ("VIE"), to which previous accounting guidance on consolidation does not apply. A VIE is an entity in which the equity investors do not have the characteristics of a controlling interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. Under FIN 46, the primary beneficiary of a VIE is required to consolidate the VIE in its financial statements. The primary beneficiary is an entity that has a variable interest that will absorb the majority of the VIE's expected losses if they occur, receive a majority of the entity's expected residual returns if they occur, or both. White Mountains adopted the disclosure provisions of FIN 46 beginning with its December 31, 2002 Form 10-K and its consolidation provisions as of March 31, 2004. See Note 15.


Mandatorily Redeemable Preferred Stock

        In July 2003, White Mountains adopted the provisions of SFAS No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity" ("SFAS 150") and it subsequently adopted FASB Staff Position No. 150-3 ("FSP 150-3") in November 2003. SFAS 150, among other things, required an issuer of mandatorily redeemable financial instruments to classify such instruments as a liability and to initially measure the liability at its fair value. Subsequently, these instruments are to be measured at their present value, using the interest rate implicit at the inception of the contract. In addition, all future dividends paid to holders of those instruments, as well as any accretion related to those instruments, are to be reflected as interest expense. FSP 150-3 was released by the FASB in November 2003 and it indefinitely deferred the fair value measurement provisions of SFAS 150 for certain mandatorily redeemable noncontrolling interests. However, the presentation provisions of SFAS 150 are still applicable to those instruments.

        White Mountains has two classes of mandatorily redeemable preferred stock of subsidiaries, which were previously classified as minority interests, that fell within the scope of SFAS 150 and are considered noncontrolling interests under FSP 150-3. Upon adoption of SFAS 150 in 2003, White Mountains reclassified these instruments from mezzanine equity to liabilities at their historical carrying values. In addition, beginning in the third quarter of 2003, all dividends and accretion on White Mountains' mandatorily redeemable preferred stock have been recorded as interest expense. See Note 10.


Stock-Based Compensation

        In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock-Based Compensation—Transition and Disclosure" ("SFAS 148"), an amendment to SFAS No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"). Among other things, SFAS 148 amends the disclosure provisions

F-12



of SFAS 123 to require prominent annual disclosure about the effects on reported net income in the Summary of Significant Accounting Policies and also requires disclosure about these effects in interim financial statements. Accordingly, the Company has adopted the applicable disclosure requirements of this statement for year-end and interim reporting.

        White Mountains' share-based compensation plans, consisting primarily of performance shares with limited use of restricted Common Share awards ("Restricted Shares") and a one-time grant of incentive stock options to acquire Common Shares ("Options"), are designed to maximize shareholder value over long periods of time by aligning the financial interests of its management with those of its owners. Performance shares are payable only upon achievement of pre-defined business goals and are valued based on the market value of Common Shares at the time awards are earned. Performance shares are typically paid in cash, though they may be paid in Common Shares at the election of the Board of Directors, or may be deferred in accordance with the terms of the Company's deferred compensation plans.

        White Mountains expenses the full cost of all its share-based compensation, including its outstanding Options. White Mountains' share-based compensation plans, consisting primarily of performance shares, are designed to maximize shareholder value over long periods of time by aligning the financial interests of its management with those of its owners. See Note 9. White Mountains accounts for these plans under the recognition and measurement principles of Accounting Principles Board Opinion No. 25 ("APB 25"), "Accounting for Stock Issued to Employees", and related interpretations, including FASB Interpretation No. 28, "Accounting for Stock Appreciation Rights and Other Variable Stock Options or Award Plans ("FIN 28"). The accounting treatment for White Mountains' Restricted Share awards under APB 25 is identical to the method prescribed by SFAS 123, whereby the Restricted Shares are valued based upon fair value at the date of issuance and charged to compensation expense ratably over the service period. Compensation expense charged to earnings for Restricted Shares was $2.0 million, $5.8 million and $16.2 million for the years ended December 31, 2004, 2003 and 2002, respectively. The accounting treatment for White Mountains' performance share awards under APB 25 is also identical to the method prescribed by SFAS 123, whereby the liability for performance share awards is measured each period based upon the current market price of the underlying Common Shares. During 2004, 2003 and 2002, White Mountains recorded compensation charges of $215.0 million, $206.6 million and $63.5 million, respectively, for outstanding performance shares.

        In 2000, the Company issued a one-time award of 81,000 Options. The Options were issued at an exercise price equal to the market value of the underlying Common Shares on February 27, 2000 (the grant date). The exercise price escalates on a straight-line basis by 6% per annum over the ten-year life of the Options. As a result, the Company's outstanding Options are accounted for as variable options under FIN 28, with compensation expense charged to earnings over the service period based on the intrinsic value of the underlying Common Shares. Compensation expense charged to earnings for Options was $9.0 million, $7.4 million and $.7 million for the years ended December 31, 2004, 2003 and 2002, respectively. At December 31, 2004, the Company had 46,530 Options outstanding (10,530 of which were exercisable) with a weighted average exercise price of $140.80 per Common Share. During the year ended December 31, 2004, 4,035 Options were exercised at an average exercise price of $139.58 per Common Share.

        White Mountains has adopted the disclosure-only provisions of SFAS 123 with respect to its outstanding Options and Restricted Shares. The following table illustrates the pro forma effect on net income and earnings per share for each period indicated as if the Company applied the fair value recognition provisions of SFAS 123 to its employee Option incentive compensation program. The effects of Restricted Share and performance share expense are not included below because the

F-13



accounting treatment that the Company follows under APB 25 is identical to the fair value accounting prescribed by SFAS 123 for these instruments.

Business Combinations

        In 2001, White Mountains adopted the provisions of SFAS No. 141, "Business Combinations", which required the recognition of all existing deferred credits (defined as the excess of fair value of acquired assets over cost) arising from business combinations prior to July 1, 2001 through the income statement as a change in accounting principle on the first day of the fiscal year beginning after December 15, 2001. In accordance with SFAS 141, White Mountains recognized its entire December 31, 2001 unamortized deferred credit balance of $682.5 million on January 1, 2002 as a cumulative effect of a change in accounting principle. SFAS 141 also requires deferred credits arising from business combinations on or after July 1, 2001 to be immediately recognized through the income statement as an extraordinary gain. See Note 2.

        On January 1, 2002, White Mountains adopted the provisions of SFAS No. 142, "Goodwill and Other Intangible Assets", which calls for the amortization of existing and prospective goodwill (defined as the excess of cost over the fair value of acquired assets) only when the assets acquired are deemed to have been impaired rather than systematically over a perceived period of benefit. SFAS 142 specifically defines impairment as the condition that exists when the carrying amount of goodwill exceeds its implied fair value and requires goodwill to be evaluated for impairment periodically. Prior to the issuance of SFAS 142, little guidance existed as to how to determine and measure goodwill impairment. As a result of the issuance of SFAS 142, White Mountains performed a discounted cash flow analysis to determine the fair value of the net assets supporting its unamortized goodwill relating primarily to its 2000 acquisition of substantially all the reinsurance operations of Risk Capital Reinsurance Company ("Risk Capital") and recognized a transitional impairment loss of $22.3 million on January 1, 2002 as a cumulative effect of a change in accounting principle.


Employer's Disclosures about Pensions and Other Post Retirement Benefits

        In December 2003, the FASB issued SFAS No. 132 (Revised 2003), "Employer's Disclosures about Pensions and Other Post Retirement Benefits," ("SFAS 132(R)"). This statement retains the disclosure requirements contained in SFAS No. 132, "Employers' Disclosures about Pensions and Other Postretirement Benefits," which it replaces. Additionally, SFAS 132(R) requires more detailed disclosures about pension plan assets, benefit obligations, cash flows, benefit costs and related information. White Mountains has included the disclosures required by SFAS 132(R) for the years ended December 31, 2004 and 2003. See Note 8.

F-14




Other-Than-Temporary Impairment Disclosures

        In December of 2003, White Mountains adopted FASB Emerging Issues Task Force ("EITF") Issue 03-01, "The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments" ("EITF 03-01"). EITF 03-01 provides new disclosure requirements for other-than-temporary impairments on debt and equity investments. Investors are required to disclose quantitative information about: (i) the aggregate amount of unrealized losses, and (ii) the aggregate related fair values of investments with unrealized losses, segregated into time periods during which the investment has been in an unrealized loss position of less than 12 months and greater than 12 months. In addition, investors are required to disclose the qualitative information that supports their conclusion that the impairments noted in the quantitative disclosures are not other-than temporary. See Note 5.

Recently Issued Accounting Pronouncements

        In December 2004, the FASB issued SFAS No. 123 (Revised 2004), "Share-Based Payment," "(SFAS 123(R)". SFAS 123(R) is a revision of FASB Statement 123, "Accounting for Stock-Based Compensation" and supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees," and its related implementation guidance. The Statement focuses primarily on accounting for transactions in which an entity obtains employee services in share-based payment transactions. SFAS No. 123 (R) requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value of the award. That cost is to be recognized over the period during which an employee is required to provide service in exchange for the award. This statement is effective as of the beginning of the first interim or annual reporting period that begins after June 15, 2005 and the Company will adopt the standard in the third quarter of fiscal 2005. White Mountains does not expect a material effect on its financial condition, results of operations or cash flows


NOTE 2. Significant Transactions

Sirius

        On April 16, 2004, White Mountains acquired Sirius from ABB Ltd. (the "Sirius Acquisition") for SEK 3.27 billion (approximately $427.5 million based upon the foreign exchange spot rate at the date of acquisition), which includes $10.5 million of expenses incurred in connection with the acquisition. The principal companies acquired were Sirius International Insurance Corporation ("Sirius International"), Sirius America Insurance Company ("Sirius America") and Scandinavian Reinsurance Company Ltd. ("Scandinavian Re"). Sirius International is domiciled in Sweden and has offices in Belgium, Hamburg, London, Singapore, Stockholm and Zurich. Sirius America is a U.S.-based insurer focused on primary insurance programs that was acquired by Folksamerica as part of the transaction. Scandinavian Re is a reinsurance company that has been in run-off since 2002.

        The Sirius Acquisition was accounted for by the purchase method of accounting and, therefore, the identifiable assets and liabilities of Sirius were recorded by White Mountains at their fair values on April 16, 2004. The process of determining the fair value of such assets and liabilities acquired was as follows: (1) the purchase price of Sirius was preliminarily allocated to the acquired assets and liabilities, based on their respective estimated fair values at April 16, 2004; (2) the excess of the estimated fair value of acquired net assets over the purchase price was used to reduce the estimated fair values of all non-current, non-financial assets acquired to zero; and (3) the remaining excess of the estimated fair value of net assets over the purchase price was recorded as an extraordinary gain.

F-15


        The fair value of identifiable assets and liabilities acquired on April 16, 2004 were as follows (in millions):

Fair value of assets acquired   $ 3,306.9  
Fair value of liabilities acquired     2,768.0  
   
 
Fair value of net assets acquired     538.9  
Total purchase price, including expenses     (427.5 )
   
 
Resulting extraordinary gain   $ 111.4  
   
 

        Significant assets and liabilities acquired through Sirius included $1,851.9 million of cash and investments, $790.1 million of funds held by ceding companies, $286.2 million of reinsurance recoverable on paid and unpaid losses, $245.8 million of insurance and reinsurance balances receivable, $1,612.7 million of loss and loss adjustment expense reserves, $432.2 million of reserves for structured settlements, $276.5 million of unearned insurance premiums and $289.4 million of deferred tax liabilities.

        Supplemental unaudited pro forma condensed combined income statement information for the year ended December 31, 2004, which assumes that the Sirius Acquisition had occurred as of January 1, 2004, and for the year ended December 31, 2003, which assumes the Sirius Acquisition had occurred as of January 1, 2003, follows:

Earnings per share:            
  Pro forma net income—basic   $ 45.83   $ 34.15
  Pro forma net income—diluted   $ 43.28   $ 30.55
   
 

        The unaudited pro forma information presented above for the years ended December 31, 2004 and 2003 has been supplied for comparative purposes only and does not purport to reflect the actual results that would have been reported had the Sirius Acquisition been consummated at January 1, 2004 and 2003, respectively. Additionally, such pro forma financial information does not purport to represent results that may occur in the future.


Symetra

        On August 2, 2004, White Mountains, Berkshire Hathaway Inc. ("Berkshire") and several other private investors capitalized Symetra Financial Corporation ("Symetra") in order to purchase the life and investments operations of Safeco Corporation for $1.35 billion. The acquired companies, which are now operating under the Symetra brand, focus mainly on group insurance, individual life insurance, structured settlements and retirement services. Symetra had an initial capitalization of approximately $1.4 billion, consisting of $1,065 million of common equity and $315 million of bank debt. White Mountains invested $194.7 million in Symetra in exchange for 2.0 million common shares of Symetra. In addition, White Mountains and Berkshire each received warrants to acquire an additional 1.1 million common shares of Symetra at $100 per share. White Mountains owns approximately 19% of the

F-16



outstanding common shares of Symetra, which are accounted for under the equity method, and approximately 24% of Symetra on a fully-converted basis including the warrants, which are accounted for under the provisions of SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("FAS 133"). Three White Mountains designees serve on Symetra's eight member board of directors.

        White Mountains recorded its initial investment in Symetra in accordance with GAAP by allocating the $194.7 million purchase price between the common shares and the warrants. The allocation was determined by recording the warrants at their fair value of $35.4 million, with the remaining $159.3 million allocated to the common shares. White Mountains then recognized an extraordinary gain of $40.7 million, representing the difference between the initial cost of the common shares and the amount of White Mountains' equity in the underlying net assets of Symetra, as required by APB 18, "The Equity Method of Accounting for Investments in Common Stock".


Sierra

        On March 31, 2004, Folksamerica acquired the Sierra Insurance Group companies (the "Sierra Group"), consisting of California Indemnity Insurance Company and its three subsidiaries, from Nevada-based Sierra Health Services, Inc. Folksamerica paid $76.2 million for the Sierra Group, which included $14.2 million in cash and a $62.0 million purchase note (see Note 6), of which $58.0 million will be adjusted over its six-year term to reflect favorable or adverse loss reserve development on the acquired reserve portfolio and run-off of remaining policies in force (mainly workers compensation business) as well as certain other balance sheet protections. The acquired companies' net assets at the time of the close were $84.8 million, including $270.3 million of investments, $174.4 million of reinsurance balances recoverable, $406.9 million of loss and loss adjustment expense reserves and $25.1 million of unearned premium. The acquisition resulted in an $8.6 million extraordinary gain, which White Mountains recognized in the first quarter of 2004.


Tryg-Baltica

        On November 11, 2004, Sirius International acquired 100% of Denmark-based Tryg-Baltica Forsikring, internationalt forsikringsselskab A/S ("Tryg Baltica"). Under the terms of the agreement, Sirius paid approximately DKK 316.3 million ($57.7 million) and an additional $0.3 million of expenses incurred in connection with the acquisition. Following the closing, White Mountains Re placed Tryg-Baltica into run-off, though it is anticipated that select business will be renewed by Sirius International. White Mountains Re did not acquire any infrastructure or employees and will manage the company's run-off administration. The acquired companies' net assets at closing were $77.5 million, including $144.3 million of cash and investments, $86.7 million of receivables, $20.8 million of deposits with insurance companies, $150.8 million of loss and LAE reserves and $36.9 million of unearned insurance premiums. The acquisition resulted in a $19.8 million extraordinary gain, which White Mountains recognized in the fourth quarter of 2004.


Other Acquisitions and Dispositions

        During the fourth quarter of 2004, OneBeacon sold two of its subsidiaries, Potomac Insurance Company of Illinois ("Potomac") for $21.7 million and Western States Insurance Company ("Western States"), as well as its boiler inspection service business, for $15.1 million and recognized combined gains on the sales of $22.1 million through other revenues.

        During the third quarter of 2004, OneBeacon entered into an agreement to sell the renewal rights to most of its pre-Atlantic Mutual (defined below) New York commercial business to Tower Insurance Group. The transaction, effective with December 1, 2004 renewals, will impact approximately

F-17



$110.0 million of premiums. OneBeacon will retain the commercial business acquired from Atlantic Mutual (defined below).

        On March 31, 2004, OneBeacon acquired Atlantic Specialty Insurance Company ("Atlantic Specialty"), a subsidiary of Atlantic Mutual Insurance Company ("Atlantic Mutual"), and the renewal rights to Atlantic Mutual's segmented commercial insurance business, including the unearned premiums on the acquired book (the "Atlantic Specialty Transaction"). The overall gross written premium for this book of business totals approximately $400 million. Under the terms of the agreement, OneBeacon will pay Atlantic Mutual a renewal commission on the premiums renewed. In connection with its acquisition of Atlantic Specialty, OneBeacon paid $30.1 million in cash and issued a $20.0 million note to the seller. See Note 6.

        During the first quarter of 2004, White Mountains purchased additional warrants to acquire 2,390,786 common shares of Montpelier Re Holdings Ltd. ("Montpelier") from an existing warrant holder for $54.1 million in cash. Also during the first quarter of 2004, White Mountains sold 4.5 million common shares of Montpelier to third parties for net proceeds of $155.3 million. As a result of this sale, as well as changes to the composition of the Board of Directors of both Montpelier and White Mountains, White Mountains changed the method of accounting for its remaining common share investment in Montpelier as of March 31, 2004 from an equity method investment in an unconsolidated affiliate to a common equity security classified as available for sale and carried at fair value. See Note 5.

        In January 2004, Folksamerica sold Peninsula to the Donegal Group for $23.3 million, or 107.5% of its GAAP book value, resulting in a pretax gain of $2.1 million, which White Mountains recognized in the first quarter of 2004.

        Effective October 1, 2003, Folksamerica acquired renewal rights to the property and casualty treaty reinsurance business of CNA Reinsurance ("CNA Re"), a division of CNA Financial Corporation. Under the terms of the transaction, Folksamerica will compensate CNA Re based upon the amount of premiums renewed by Folksamerica over the next two contract renewals. No reserves or liabilities were transferred. In connection with this transaction, Folksamerica established an underwriting office in Chicago staffed with a number of reinsurance professionals previously employed by CNA Re.

        In December 2003, OneBeacon sold one of its wholly-owned subsidiaries, NFU Standard, to Quanta U.S. Holdings, Inc., an indirect subsidiary of Quanta Capital Holdings Ltd. OneBeacon received total proceeds of $22.4 million and recorded an $8.7 million gain on the sale, which is included in other revenues. Concurrently, OneBeacon entered into an assumption reinsurance agreement to assume all in-force insurance contracts of NFU Standard, subject to regulatory and other approvals.

        In April 2002, Folksamerica acquired Imperial Casualty and Indemnity Insurance Company ("Imperial") for $4.2 million including related expenses ($.5 million net of cash acquired). Significant assets and liabilities acquired included investments of $22.8 million and gross loss and LAE reserves of $11.9 million. In accordance with SFAS 141, White Mountains recognized a $7.1 million extraordinary gain during 2002 representing the excess of the fair value of Imperial's net assets over its cost.


NOTE 3. Reserves for Unpaid Losses and Loss Adjustment Expenses

Insurance

        White Mountains' insurance subsidiaries establish loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for insured events that have already occurred. The process of estimating reserves involves a considerable degree of judgment by management and, as of any given date, is inherently uncertain.

F-18



        Reserves are typically comprised of (1) case reserves for claims reported and (2) reserves for losses that have occurred but for which claims have not yet been reported, referred to as incurred but not reported ("IBNR") reserves, which include a provision for expected future development on case reserves. Case reserves are estimated based on the experience and knowledge of claims staff regarding the nature and potential cost of each claim and are adjusted as additional information becomes known or payments are made. IBNR reserves are derived by subtracting paid loss and LAE and case reserves from estimates of ultimate loss and LAE. Actuaries estimate ultimate loss and LAE using various generally accepted actuarial methods applied to known losses and other relevant information. Like case reserves, IBNR reserves are adjusted as additional information becomes known or payments are made.

        Ultimate loss and LAE are generally determined by extrapolation of claim emergence and settlement patterns observed in the past that can reasonably be expected to persist into the future. In forecasting ultimate loss and LAE with respect to any line of business, past experience with respect to that line of business is the primary resource, but cannot be relied upon in isolation. White Mountains' own experience, particularly claims development experience, such as trends in case reserves, payments on and closings of claims, as well as changes in business mix and coverage limits, is the most important information for estimating its reserves. External data, available from organizations such as statistical bureaus, consulting firms and reinsurance companies, is sometimes used to supplement or corroborate White Mountains' own experience, and can be especially useful for estimating costs of new business. For some lines of business, such as "long-tail" coverages discussed below, claims data reported in the most recent accident year is often too limited to provide a meaningful basis for analysis due to the typical delay in reporting of claims. For this type of business, White Mountains uses a selected loss ratio method for the initial accident year or years. This is a standard and accepted actuarial reserve estimation method in these circumstances in which the loss ratio is selected based upon information used in pricing policies for that line of business, as well as any publicly available industry data, such as industry pricing, experience and trends, for that line of business.

        Uncertainties in estimating ultimate loss and LAE are magnified by the time lag between when a claim actually occurs and when it is reported and settled. This time lag is sometimes referred to as the "claim-tail". The claim-tail for most property coverages is typically short (usually a few days up to a few months). The claim-tail for liability/casualty coverages, such as automobile liability, general liability, products liability, multiple peril coverage, and workers compensation, can be especially long as claims are often reported and ultimately paid or settled years, even decades, after the related loss events occur. During the long claims reporting and settlement period, additional facts regarding coverages written in prior accident years, as well as about actual claims and trends may become known and, as a result, White Mountains may adjust its reserves. If management determines that an adjustment is appropriate, the adjustment is booked in the accounting period in which such determination is made in accordance with GAAP. Accordingly, should reserves need to be increased or decreased in the future from amounts currently established, future results of operations would be negatively or positively impacted, respectively.

        In determining ultimate loss and LAE, the cost to indemnify claimants, provide needed legal defense and other services for insureds and administer the investigation and adjustment of claims are considered. These claim costs are influenced by many factors that change over time, such as expanded coverage definitions as a result of new court decisions, inflation in costs to repair or replace damaged property, inflation in the cost of medical services and legislated changes in statutory benefits, as well as by the particular, unique facts that pertain to each claim. As a result, the rate at which claims arose in the past and the costs to settle them may not always be representative of what will occur in the future. The factors influencing changes in claim costs are often difficult to isolate or quantify and developments in paid and incurred losses from historical trends are frequently subject to multiple and conflicting interpretations. Changes in coverage terms or claims handling practices may also cause future experience and/or development patterns to vary from the past. A key objective of actuaries in

F-19



developing estimates of ultimate loss and LAE, and resulting IBNR reserves, is to identify aberrations and systemic changes occurring within historical experience and accurately adjust for them so that the future can be projected reliably. Because of the factors previously discussed, this process requires the use of informed judgment and is inherently uncertain.

Reinsurance

        White Mountains' reinsurance subsidiaries establish loss and LAE reserves that are estimates of amounts needed to pay claims and related expenses in the future for reinsured events that have already occurred. White Mountains' reinsurance subsidiaries also obtain reinsurance whereby another reinsurer contractually agrees to indemnify White Mountains for all or a portion of the reinsurance risks underwritten by White Mountains. Such arrangements, where one reinsurer provides reinsurance to another reinsurer, are usually referred to as "retrocessional reinsurance" arrangements. White Mountains establishes estimates of amounts recoverable from retrocessional reinsurance in a manner consistent with the loss and LAE liability associated with reinsurance contracts offered to its customers (the "ceding companies"), net of an allowance for uncollectible amounts. Net reinsurance loss reserves represent loss and LAE reserves reduced by retrocessional reinsurance recoverable on unpaid losses.

        Reinsurance loss and LAE reserve estimates reflect the judgment of both the ceding companies and White Mountains, based on the experience and knowledge of their respective claims personnel, regarding the nature and value of the claims. The ceding companies may periodically adjust the amount of the case reserves as additional information becomes known or partial payments are made. Upon notification of a loss from a ceding company, White Mountains establishes case reserves, including LAE reserves, based upon White Mountains' share of the amount of reserves established by the ceding company and White Mountains' independent evaluation of the loss. In cases where available information indicates that reserves established by the ceding company are inadequate, White Mountains establishes reserves in excess of its share of the reserves established by the ceding company.

        The estimation of net reinsurance loss and LAE reserves is subject to the same factors as the estimation of insurance loss and LAE reserves. In addition to those factors which give rise to inherent uncertainties in establishing insurance loss and LAE reserves, the claim-tail for reinsurers is further extended because claims are first reported through one or more intermediary insurers or reinsurers.

        White Mountains establishes loss reserves for White Mountains Re based on a single point estimate, which is management's best estimate of ultimate losses and loss expenses. This "best estimate" is derived from a combination of methods. For current accident year business the estimate is based on an expected loss ratio method. The parameters underlying this method are developed during the underwriting and pricing process. Loss ratio expectations are derived for each contract and these are aggregated by class of business and type of contract. These loss ratios are then applied to the actual earned premiums by class and type of business to estimate ultimate losses. Paid losses are deducted to determine loss and loss expense reserves.

        For prior accident years, White Mountains Re gradually replaces this expected loss ratio approach with estimates based on historical loss reporting patterns. For both current and prior accident years estimates change when new information becomes available, such as changing loss emergence patterns, or claim and underwriting audits.

        Once a point estimate is established, in the case of White Mountains Re, actuaries estimate loss reserve ranges to measure the sensitivity of the actuarial assumptions used to set the point estimates. These ranges are calculated using similar methods to the point estimate calculation, but with different expected loss ratio and loss reporting pattern assumptions. For the low estimate, more optimistic loss ratios and faster reporting patterns are assumed, while the high estimate uses more conservative loss ratios and slower reporting patterns. These variable assumptions are derived from historical variations

F-20



in loss ratios and reporting patterns by class and type of business. Due to the inherent difficulties in estimating ultimate A&E exposures, White Mountains Re does not estimate ranges of these reserves.

Loss and LAE development—2004

        White Mountains experienced $115.1 million of net unfavorable development on prior accident year loss and LAE reserves during 2004, of which approximately $100.3 million (relating primarily to 2002 and prior accident years) was experienced by OneBeacon and approximately $10.8 million was experienced by White Mountains Re.

        The 2004 development related primarily to personal auto liability, general liability and multiple peril reserves due in part to emerging trends in claims experienced in OneBeacon's run-off operations,

F-21



as well as national account and program claims administered by third parties. These claim trends principally included higher defense costs and higher damages from liability assessments.

        The majority of the unfavorable development recorded at White Mountains Re resulted from certain discontinued lines at Folksamerica as well as run-off operations acquired as part of the Sirius Acquisition. This unfavorable development was partially offset by favorable development in the Sirius International reserve portfolio, mainly from the three most recent underwriting years, and is indicative of the favorable terms and conditions that have existed in the global reinsurance marketplace during that time. Additionally, White Mountains Re recorded $10.0 million of unfavorable loss development on its workers compensation reserves acquired as part of the Sierra Group acquisition in 2004. This unfavorable development was offset by a reduction to the purchase note issued in connection with the acquisition of the Sierra Group.

Loss and LAE development—2003

        White Mountains recorded $189.4 million of net unfavorable loss reserve development on prior accident year loss and LAE reserves during 2003, of which approximately $146.9 million (relating primarily to 2000 and prior accident years) was experienced by OneBeacon and $45.5 million was experienced by White Mountains Re.

        The majority of the net unfavorable development at OneBeacon in 2003 was due to a $97.7 million increase related to construction defect claims in its run-off operations. The development at OneBeacon in 2003 also included approximately $12.0 million for a significant 1995 property claim from a pool in which OneBeacon had participated (the Industrial Risk Insurers pool) which was settled through an arbitration decision during 2003.

        White Mountains Re experienced approximately $45.5 million of unfavorable loss reserve development during 2003, primarily due to strengthening of A&E reserves and reserves on Risk Capital casualty lines. White Mountains Re's 2003 loss development for A&E exposures was due to the completion of a detailed A&E market share study. This study was based on White Mountains Re's share of industry paid losses to estimated industry carried reserves.

Loss and LAE development—2002

        Prior accident year losses of $90.0 million incurred in 2002 consisted primarily of $57.4 million recorded during 2002 at OneBeacon, $17.0 million recorded at White Mountains Re, $10.5 million recorded at Fund American Re and $5.1 million recorded at White Mountains' other insurance subsidiaries.

        OneBeacon's prior year development recorded in 2002 was comprised of a $97.4 million increase related to accident years 2000 and prior, while reserves for accident year 2001 were reduced by $40.0 million. Reserve increases for 2000 and prior accident years primarily relate to increases in reserves for workers compensation coverages of $155.3 million (on reserves as of December 31, 2001 of $1.2 billion) reduced primarily by favorable development in general liability coverages and decreases in reserves for unallocated LAE totaling approximately $57.9 million. Workers compensation reserves for accident year 2000 and prior increased related primarily to a continuing unfavorable trend of increases in workers compensation medical claims and indemnity costs. Based on a study provided by the NCCI, workers compensation medical claims costs rose an average of 14% during 2002, compared with an average of 12% during 2001. Average workers compensation indemnity costs rose 11% during 2002 compared with an increase of 9% during 2001. Decreases in reserves for unallocated LAE resulted from completion of an activity-based-cost study which indicated future claim servicing costs were less than originally projected. This decrease primarily related to multiple peril and general liability coverages. The reduction in reserves for accident year 2001 was due in large part to favorable development on property losses from the Attacks.

F-22



        The prior year development recorded in 2002 at White Mountains Re consisted primarily of (i) additional losses of $9.7 million relating to the Attacks, (ii) additional losses of $7.3 million from aviation insurance coverage, in relation to the Risk Capital business, (iii) reserve additions relating to asbestos and environmental losses of $11.4 million, (iv) $3.5 million of adverse development relating to the remaining business from the USF Re acquisition, offset by (v) $17.0 million of net income recorded during the first quarter relating to the reversal of an allowance for doubtful reinsurance recoveries related to PCA. These losses, with exception of the those relating to the Attacks, are covered under the Imagine Cover, and were partially offset by amortization of the deferred gain related to retroactive reinsurance.

Fair value adjustment

        In connection with purchase accounting for the OneBeacon Acquisition, White Mountains was required to adjust to fair value OneBeacon's loss and LAE reserves and the related reinsurance recoverables by reducing them by $646.9 million and $346.9 million, respectively, on OneBeacon's acquired balance sheet. This reduction to net loss and LAE reserves of $300.0 million is being accreted through an income statement charge ratably over the period that the claims are expected to be settled. As a result, White Mountains recognized $33.2 million, $48.6 million and $79.8 million of accretion to loss and LAE reserves during 2004, 2003 and 2002, respectively. White Mountains will accrete the remaining $82.4 million over the future periods in which the claims are settled, which is expected to be seven or eight years from the OneBeacon Acquisition.

        In connection with purchase accounting for the Sirius Acquisition, White Mountains was required to adjust to fair value the loss and LAE reserves on Sirius' acquired balance sheet by $58.1 million. This fair value adjustment is being recognized through an income statement charge ratably with and over the period the claims are settled. As such, White Mountains recognized $10.1 million of such charges for the year ended December 31, 2004.

        The fair values of OneBeacon's loss and LAE reserves and related reinsurance recoverables acquired on June 1, 2001 and Sirius' loss and LAE reserves and related reinsurance recoverables acquired on April 16, 2004 were based on the present value of their expected cash flows with consideration for the uncertainty inherent in both the timing of, and the ultimate amount of, future payments for losses and receipts of amounts recoverable from reinsurers. In estimating fair value, management adjusted the nominal loss reserves of OneBeacon (net of the effects of reinsurance obtained from the NICO Cover and the GRC Cover) and Sirius and discounted them to their present value using an applicable risk-free discount rate. The series of future cash flows related to such loss payments and reinsurance recoveries were developed using OneBeacon's and Sirius' historical loss data. The resulting discount was reduced by the "price" for bearing the uncertainty inherent in OneBeacon's and Sirius' net loss reserves in order to estimate fair value. This was approximately 11% and 12% of the present value of the expected underlying cash flows of the loss reserves and reinsurance recoverables of OneBeacon and Sirius, respectively, which is believed to be reflective of the cost OneBeacon and Sirius would incur if they had attempted to reinsure the full amount of its net loss and LAE reserves with a third party reinsurer.


Asbestos and environmental loss and loss adjustment expense reserve activity

        White Mountains' reserves include provisions made for claims that assert damages from A&E related exposures. Asbestos claims relate primarily to injuries asserted by those who came in contact with asbestos or products containing asbestos. Environmental claims relate primarily to pollution and related clean-up costs obligations, particularly as mandated by federal and state environmental protection agencies. In addition to the factors described above regarding the reserving process, White Mountains estimates its A&E reserves based upon, among other factors, facts surrounding reported cases and exposures to claims, such as policy limits and deductibles, current law, past and projected

F-23



claim activity and past settlement values for similar claims, as well as analysis of industry studies and events, such as recent settlements and asbestos-related bankruptcies. The cost of administering A&E claims, which is an important factor in estimating loss reserves, tends to be higher than in the case of non-A&E claims due to the higher legal costs typically associated with A&E claims. Due to the inherent difficulties in estimating ultimate A&E exposures, OneBeacon does not estimate a range for A&E incurred losses.

        Immediately prior to White Mountains' acquisition of OneBeacon, OneBeacon purchased a reinsurance contract with NICO under which OneBeacon is entitled to recover from NICO up to $2.5 billion in the future for asbestos claims arising from business written by OneBeacon in 1992 and prior, environmental claims arising from business written by OneBeacon in 1987 and prior, and certain other exposures. Under the terms of the NICO Cover, NICO receives the economic benefit of reinsurance recoverables from certain of OneBeacon's third party reinsurers in existence at the time the NICO Cover was executed ("Third Party Recoverables"). As a result, the Third Party Recoverables serve to protect the $2.5 billion limit of NICO coverage for the benefit of OneBeacon. Any amounts uncollectible from third party reinsurers due to dispute or the reinsurers' financial inability to pay are covered by NICO under its agreement with OneBeacon. Third Party Recoverables are typically for the amount of loss in excess of a stated level each year. Of claim payments in the past 11 years, approximately 63% of asbestos losses and 39% of environmental losses have been recovered under the historical third party reinsurance.

        OneBeacon estimates that on an incurred basis it has exhausted approximately $1.7 billion of the coverage provided by NICO at December 31, 2004. At December 31, 2004, $14.3 million of the $1.7 billion of exhausted coverage from NICO related to uncollectible Third Party Recoverables. Net losses paid totaled approximately $682 million as of December 31, 2004, with $95 million paid in 2004. Asbestos payments during 2004 reflect payments resulting from intensified efforts by claimants to resolve asbestos claims prior to enactment of potential Federal asbestos legislation. To the extent that OneBeacon's estimate of ultimate A&E losses as well as the estimate and collectibility of Third Party Recoverables differs from actual experience, the remaining protection under the NICO Cover may be more or less than the approximate $757 million that OneBeacon estimates remained at December 31, 2004.

        For purposes of determining available reinsurance, product liability asbestos claims typically are aggregated as a single loss within each policy period. As a result, losses often exceed the retention level under the reinsurance agreement and reinsurance recoveries are obtained. However, for claims being asserted under premises and operations coverage, the losses are generally not aggregated for purposes of determining reinsurance recoveries, so OneBeacon expects that in the future a smaller percentage of these losses will be covered as Third Party Recoverables than has been true historically of products liability asbestos losses.

        White Mountains' reserves for A&E losses at December 31, 2004 represent management's best estimate of its ultimate liability based on information currently available. However, as case law expands, medical and clean-up costs increase and industry settlement practices change, White Mountains may be subject to asbestos and environmental losses beyond currently estimated amounts. White Mountains cannot reasonably estimate at the present time loss reserve additions arising from any such future unfavorable developments and cannot be sure that allocated loss reserves, plus the remaining capacity under the NICO Cover and other reinsurance contracts, will be sufficient to cover additional liability arising from any such unfavorable developments.

        The following tables summarize reported asbestos and environmental loss and LAE reserve activities (gross and net of reinsurance) for OneBeacon, White Mountains Re and White Mountains' other operations, consisting of American Centennial and British Insurance Company, for the years ended December 31, 2004, 2003 and 2002, respectively.

The asbestos and environmental reserve activity for White Mountains' other operations is comprised of American Centennial and British Insurance Company, two insurance subsidiaries that have been in run-off since 1985. The majority of the A&E reserves from other operations are recorded at American Centennial. At December 31, 2004, American Centennial had 33 open asbestos and environmental claims of which 19 were asbestos related claims and 14 were environmental related claims.


NOTE 4. Third Party Reinsurance

        In the normal course of business, White Mountains' insurance and reinsurance subsidiaries seek to limit losses that may arise from catastrophes or other events by reinsuring with third party reinsurers. White Mountains remains liable for risks reinsured even if the reinsurer does not honor its obligations

F-26



under reinsurance contracts. The effects of reinsurance on White Mountains' insurance and reinsurance subsidiaries' written and earned premiums and on loss and LAE were as follows:

Assumed amounts principally relate to business assumed under the Liberty Agreement.

OneBeacon

        In the ordinary course of its business, OneBeacon purchases reinsurance from high-quality, highly rated third party reinsurers in order to provide diversification of its business and minimize loss from large risks or catastrophic events. OneBeacon uses PML forecasting to quantify its exposure to catastrophic losses.

        The timing and size of catastrophe losses are unpredictable and the level of losses experienced in any year could be material to OneBeacon's operating results and financial position. Examples of catastrophes include losses caused by earthquakes, wildfires, hurricanes and other types of storms and terrorist acts. The extent of losses caused by catastrophes is both a function of the amount and type of insured exposure in an area affected by the event and the severity of the event. OneBeacon continually assesses and implements programs to manage its exposure to catastrophe losses through individual risk selection and by limiting its concentration of insurance written in catastrophe-prone areas, such as coastal regions. In addition, OneBeacon imposes wind deductibles on existing coastal windstorm exposures. OneBeacon's largest single natural catastrophe risk is Northeast windstorm. OneBeacon seeks to further reduce its exposure to catastrophe losses through the purchase of catastrophe reinsurance. OneBeacon uses PML forecasting to quantify its exposure to catastrophic losses. PML is a statistical modeling technique that measures a company's catastrophic exposure as the maximum probable loss in a given time period.

        Since the terrorist attacks of September 11, 2001 (the "Attacks"), OneBeacon has sought to mitigate the risk associated with any future terrorist attacks by reducing the insured value of policies written in geographic areas with a high concentration of exposure to losses from terrorist attacks or by seeking to exclude coverage for such losses from their policies.

        On November 26, 2002, President Bush signed the Terrorism Risk Insurance Act (the "Terrorism Act") establishing a federal "backstop" for commercial property and casualty losses, including workers compensation, resulting from acts of terrorism by or on behalf of any foreign person or foreign interest. The Terrorism Act requires primary commercial insurers to make terrorism coverage available

F-28


immediately and provides Federal protection above individual company retention and aggregate industry retention levels. OneBeacon estimates its individual retention level for commercial policies subject to the Terrorism Act to be approximately $160.0 million in 2005. Aggregate industry retention levels are $15.0 billion for 2005. The Federal government will pay 90% of covered terrorism losses that exceed either OneBeacon's or the industry's retention levels up to $100.0 billion. The fate of the Terrorism Act beyond 2005 remains uncertain. It is anticipated that Congress will likely rule on a possible extension during the summer of 2005; however, there is a chance that the Terrorism Act could expire on December 31, 2005.

        Effective July 1, 2004, OneBeacon renewed its normal property catastrophe reinsurance program to cover its full estimated PML (one-in-250 year) through June 30, 2005. Under that cover, the first $200.0 million of losses resulting from any single catastrophe are retained by OneBeacon and losses from a single event in excess of $200.0 million and up to $850.0 million are reinsured for 100% of the loss. In the event of a catastrophe, OneBeacon can reinstate its property catastrophe reinsurance program for the remainder of the original contract term by paying a reinstatement premium which is based on the percentage of coverage reinstated and the original property catastrophe coverage premium.

        OneBeacon's property catastrophe reinsurance program does not cover personal or commercial property losses resulting from nuclear, biological or chemical terrorist attacks. The program covers personal property losses resulting from other types of terrorist attacks, and commercial property losses resulting from other types of domestic terrorist attacks or events not "certified" as defined under the Terrorism Act. The Terrorism Act provides protection for commercial property losses for certified events including those arising from nuclear, biological, or chemical attacks.

        OneBeacon also purchases individual property reinsurance coverage for certain risks to reduce large loss volatility. The Property per Risk reinsurance program reinsures losses in excess of $5.0 million up to $75.0 million. Individual risk facultative reinsurance may be purchased above $75.0 million where OneBeacon deems it appropriate. The Property per Risk treaty also reinsures losses in excess of $10.0 million up to $75.0 million on an individual risk basis for terrorism losses. However nuclear, biological, and chemical events are not covered.

        OneBeacon also maintains a casualty reinsurance program which provides protection for catastrophe losses involving workers compensation, general liability or automobile liability in excess of $5.0 million up to $60.0 million. This program provides one full $55.0 million limit for either "certified" or "non-certified" terrorism losses but does not provide coverage for losses resulting from nuclear, biological or chemical attacks.

        In connection with the OneBeacon Acquisition, Aviva caused OneBeacon to purchase reinsurance contracts with two reinsurance companies rated "AAA" (Extremely Strong) by Standard & Poor's and "A++" (Superior) by A.M. Best: a full risk-transfer cover from National Indemnity Company ("NICO") for up to $2.5 billion in old asbestos and environmental claims (the "NICO Cover") and an adverse development cover from General Reinsurance Corporation ("GRC") for up to $400.0 million on additional losses occurring in accident years 2000 and prior (the "GRC Cover").

        Reinsurance contracts do not relieve OneBeacon of its obligation to its ceding companies. Therefore, collectibility of balances due from its reinsurers is critical to OneBeacon's financial strength. The following table provides a listing of OneBeacon's top reinsurers, excluding industry pools and

associations and affiliates of White Mountains, based upon recoverable amounts, the percentage of total reinsurance recoverables and the reinsurer's A.M. Best rating.

White Mountains Re

        White Mountains Re has exposure to losses caused by hurricanes, earthquakes, winter storms, windstorms, terrorist acts and other catastrophic events. In the normal course of business, White Mountains Re seeks to reduce the risk of loss that may arise from catastrophes or other events that cause unfavorable underwriting results by reinsuring certain levels of risk in various areas of exposure with other insurance and reinsurance enterprises and by closely monitoring aggregate property exposures and related PMLs. To manage and analyze aggregate exposures and PML, White Mountains Re utilizes a variety of tools and analyses, including catastrophe modeling software packages. White Mountains Re regularly assesses its concentration of underwriting exposures in catastrophe prone areas and develops strategies to manage this exposure, primarily through limiting accumulation of exposure to acceptable levels and, if deemed necessary, the purchase of catastrophe reinsurance.

        Folksamerica's primary reinsurance protections are through quota share arrangements with Olympus. Folksamerica's retrocessional arrangements with Olympus are designed to increase Folksamerica's capacity to capitalize on the improved pricing trends that accelerated after the Attacks and to reduce its potential loss exposure to any large, or series of smaller, property catastrophe events. Under the quota share agreements with Olympus, Folksamerica cedes up to 75% of substantially all of its short-tailed excess of loss business, mainly property and marine, and 50% of its proportional property business to Olympus and receives an override commission on the premiums ceded to Olympus.

        Effective April 1, 2004, Sirius International entered into a quota share reinsurance agreement with Olympus. Under this agreement, Sirius International cedes 25% of its new and renewal short-tailed proportional and excess of loss business to Olympus. White Mountains Re receives an override commission on the premiums ceded to Olympus.

        In 2000, Folksamerica purchased a reinsurance contract from Imagine Re (the "Imagine Cover") to reduce its statutory operating leverage and protect its surplus from adverse development relating to A&E exposures as well as the reserves assumed in several recent acquisitions. In accordance with

F-30



SFAS 113, amounts related to reserves transferred to Imagine Re for liabilities incurred as a result of past insurable events have been accounted for as retroactive reinsurance. At December 31, 2004 and 2003, Folksamerica's reinsurance recoverables included $260.4 million and $312.4 million, respectively, recorded under the Imagine Re Cover. All balances due from Imagine are fully collateralized, either with Folksamerica as the beneficiary of invested assets in a trust, with funds held, or through a letter of credit. As of December 31, 2003, the entire $115.0 million limit available under this contract had been fully utilized. At December 31, 2004 and 2003, Folksamerica had recorded $42.5 million and $50.6 million in deferred gains, respectively, related to retroactive reinsurance with Imagine Re. White Mountains Re is recognizing these deferred gains into income over the expected settlement period of the underlying claims, and accordingly recognized $8.1 million, $8.2 million and $8.5 million of such deferred gains during 2004, 2003 and 2002, respectively.

        Reinsurance contracts do not relieve White Mountains Re of its obligation to its ceding companies.

        In 2001, the Company received warrants to acquire 4,781,572 common shares of Montpelier at $16.67 per share (as adjusted for stock splits) that are exercisable until December 2011. During the first quarter of 2004, White Mountains sold 4.5 million common shares of Montpelier to third parties for net proceeds of $155.3 million, resulting in a pretax realized gain of $35.2 million. Also during the first quarter of 2004, White Mountains purchased additional warrants to acquire 2,390,786 common shares of Montpelier from an existing warrant holder for $54.1 million in cash, thereby raising the total number of such warrants owned by White Mountains to 7,172,358.

        The following table summarizes White Mountains' investment in Montpelier as of December 31, 2004 and December 31, 2003:

        White Mountains accounts for its Montpelier and Symetra warrants (see Note 2) under FAS 133 as a component of other investments, recording the instruments at fair value with changes in fair value recognized through the income statement as a realized investment gain or loss. The Montpelier and Symetra warrants are valued using the Black-Scholes valuation method. The major assumptions used in valuing the Montpelier warrants were a risk-free rate of 3.25%, volatility of 30% and an expected life of approximately 3 years. The major assumptions used in valuing the Symetra warrants were a risk-free rate of 3.63%, volatility of 29% and an expected life of approximately 5 years.

        White Mountains recorded investment gains of $15.7 million, $32.5 million and $58.0 million for the years ended December 31, 2004, 2003 and December 31, 2002, respectively related to its Montpelier warrants. White Mountains recorded an investment gain of $1.9 million for the year ended December 31, 2004 related to its Symetra warrants.

        As of December 31, 2004 and 2003, White Mountains reported $30.9 million and $371.6 million, respectively, in accounts payable on unsettled investment purchases and $19.9 million and $9.1 million, respectively in accounts receivable on unsettled investment sales. The 2003 payable related primarily to

F-32



an unsettled purchase of a Swedish Treasury Bill bought with funds used to purchase Sirius previous to the closing of the acquisition, which was included in short-term investments at December 31, 2003.

        Net realized investment gains were reduced by mark-to-market realized losses of $4.2 million and $47.4 million for the years ended December 31, 2003 and 2002, respectively in connection with White Mountains' interest rate swap agreements, which were undertaken to achieve a fixed interest rate on the Old Bank Facility. These interest rate swaps were terminated in May 2003 in connection with the repayment of the Old Bank Facility. Additionally, OneBeacon recorded a $5.4 million write-down of its surplus note investment in New Jersey Skylands Insurance Association during 2003, which is reflected in White Mountains' net realized investment gains.

        White Mountains' consolidated insurance and reinsurance operations are required to maintain deposits with certain insurance regulatory agencies in order to maintain their insurance licenses. The fair value of such deposits totalled $940.3 million and $592.7 million as of December 31, 2004 and 2003, respectively.

        Sales and maturities of investments, excluding short-term investments, totalled $7,466.8 million, $18,662.5 million and $13,943.8 million for the years ended December 31, 2004, 2003 and 2002, respectively. There were no non-cash exchanges or involuntary sales of investment securities during 2004, 2003 or 2002.

        The Company participates in a securities lending program whereby it loans investment securities to other institutions for short periods of time. The Company receives a fee from the borrower in return for the use of its assets and its policy is to require collateral equal to approximately 102% of the fair value of the loaned securities, which is held by a third party. All securities loaned can be redeemed on short notice. The total market value of the Company's securities on loan at December 31, 2004 was $580.7 million with corresponding collateral of $593.3 million.

Impairment

        White Mountains' portfolio of fixed maturity investments is comprised primarily of investment grade corporate debt securities, U.S. government and agency securities and mortgage-backed securities and are classified as available for sale. At December 31, 2004, approximately 99% of White Mountains' fixed maturity investments received an investment grade rating from S&P or from Moody's if a given security is unrated by S&P. White Mountains expects to continue to invest primarily in high quality, fixed maturity investments. Nearly all the fixed maturity investments currently held by White Mountains are publicly traded, and as such are considered to be liquid.

F-35


        Temporary losses on investment securities are recorded as unrealized losses. Temporary losses do not impact net income and earnings per common share but serve to reduce comprehensive net income, shareholders' equity and tangible book value. Unrealized losses subsequently identified as other-than-temporary impairments are recorded as realized losses. Other-than-temporary impairments previously recorded as unrealized losses do not impact comprehensive net income, shareholders' equity and tangible book value but serve to reduce net income and earnings per common share.

        White Mountains' methodology of assessing other-than-temporary impairments is based on security-specific facts and circumstances as of the balance sheet date. As a result, subsequent adverse changes in an issuers' credit quality or subsequent weakening of market conditions that differ from expectations could result in additional other-than-temporary impairments. In addition, the sale of a fixed maturity security with a previously recorded unrealized loss would result in a realized loss. Either of these situations would adversely impact net income and earnings per common share but would not impact comprehensive net income, shareholders' equity or tangible book value.

        The following table presents an analysis of the continuous periods during which White Mountains has held investment positions which were carried at an unrealized loss as of December 31, 2004 (excluding short-term investments):

        During the year ended December 31, 2004, White Mountains experienced $3.0 million in pre-tax, other-than-temporary impairment charges, comprised of $2.5 million taken on equity securities, and $.5 million on several limited partnership investments included in other investments. Of the charge taken on equity securities, $1.3 million was related to White Mountains' investment in the common stock of Callaway Golf Company and the remaining $1.2 million related to two other equity positions, neither of which were individually significant. White Mountains recorded the other-than-temporary impairments primarily due to the fact that the unrealized loss position on these securities was greater

F-36



than 20% of White Mountains' cost over the previous six-month period and also that certain factors have been reported by those companies which affect the likelihood that White Mountains will recover the original cost of its investment. White Mountains did not experience any other material impairment charges relating to any other individual investment security during the three years ended December 31, 2004.

        White Mountains believes that the gross unrealized losses relating to its fixed maturity investments at December 31, 2004 resulted primarily from increases in market interest rates from the dates that certain investments within that portfolio were acquired as opposed to fundamental changes in the credit quality of the issuers of such securities. Therefore, these decreases in value are viewed as being temporary because White Mountains has the intent and ability to retain such investments for a period of time sufficient to allow for any anticipated recovery in market value. White Mountains also believes that the gross unrealized losses recorded on its common equity securities and its other investments at December 31, 2004 resulted primarily from decreases in quoted market values from the dates that certain investments securities within that portfolio were acquired as opposed to fundamental changes in the issuer's financial performance and near-term financial prospects. Therefore, these decreases are also viewed as being temporary. However, due to the inherent risk involved in investing in the equity markets, it is possible that the decrease in market value of these investments may ultimately prove to be other than temporary. As of December 31, 2004, White Mountains' investment portfolio did not include any investment securities with an after-tax unrealized loss of more than $2.0 million.

Senior Notes

        In May 2003, Fund American issued $700.0 million face value of senior unsecured debt through a public offering, at an issue price of 99.7%. The Senior Notes bear an annual interest rate of 5.9%,

F-37



payable semi-annually in arrears on May 15 and November 15, until maturity on May 15, 2013, and are fully and unconditionally guaranteed as to the payment of principal and interest by the Company. Fund American incurred $7.3 million in expenses related to the issuance of the Senior Notes (including the $4.5 million underwriting discount), which have been deferred and are being recognized into interest expense over the life of the Senior Notes. Taking into effect the amortization of the original issue discount and all underwriting and issuance expenses, the Senior Notes have an effective yield to maturity of approximately 6.0% per annum.


Bank Facility

        In September 2003, Fund American established a $300.0 million revolving credit facility (the "Bank Facility") under which both Fund American and the Company are permitted borrowers. In August 2004, Fund American restructured and re-syndicated the Bank Facility to increase the availability under the revolving credit facility to $400.0 million and to extend the maturity from September 2006 to August 2009. Under the Bank Facility, the Company guarantees all obligations of Fund American, and Fund American guarantees all borrowings of the Company, subject to certain limitations imposed by the terms of the Berkshire Preferred Stock. As of December 31, 2004, the Bank Facility was undrawn.


Other Debt of Operating Subsidiaries

        In connection with its acquisition of the Sierra Group on March 31, 2004, Folksamerica entered into a $62.0 million purchase note (the "Sierra Note"), $58.0 million of which will be adjusted over its approximate six-year term to reflect favorable or adverse loss reserve development on the acquired reserve portfolio and run-off of remaining policies in force (mainly workers compensation business) as well as certain other balance sheet protections. During 2004, the Sierra Note was reduced by $12.0 million as a result of adverse development on the acquired reserves and run-off of unearned premium. Interest will accrue on the unpaid balance of the Sierra Note at a rate of 4.0% per annum, compounded quarterly, and will be payable at its maturity.

        In connection with its acquisition of Atlantic Specialty on March 31, 2004, OneBeacon issued a $20.0 million ten-year note to the seller (the "Atlantic Specialty Note"). OneBeacon is required to repay $2.0 million of principal on the notes per year, commencing with the first payment due on January 1, 2007. The note accrues interest at a rate of 5.2% except that the outstanding principal amount in excess of $15.0 million accrues interest at a rate of 3.6%.

        OBPP and Folksamerica Specialty Underwriting, Inc. ("FSUI") have borrowed $8.0 million and $7.0 million, respectively, from Dowling & Partners Connecticut Fund III, LP ("Fund III") in connection with an incentive program sponsored by the State of Connecticut known as the Connecticut Insurance Reinvestment Act (the "CIR Act"). The CIR Act provides for Connecticut income tax credits to be granted for qualifying investments made by approved fund managers. The loans made by Fund III to OBPP and FSUI are qualifying investments and, together, have the potential to generate up to $15 million of tax credits that would be shared equally between Fund III on the one hand and OBPP and FSUI on the other. The borrowings mature in April 2007 and bear interest at the option of OBPP and FSUI at either (1) the greater of (a) the prime rate minus 1% and (b) the federal funds rate minus 0.50% or (2) the eurodollar rate plus 0.325%.

        In connection with its acquisition of C-F Insurance Company in September 2001, Folksamerica issued a $25.0 million note to the seller (the "C-F Seller Note".) On August 27, 2004, Folksamerica paid off the remaining balance of this note.

Interest

        Total interest expense incurred by White Mountains for its indebtedness was $49.1 million, $48.6 million and $71.8 million in 2004, 2003 and 2002, respectively. Total interest paid by White Mountains for its indebtedness was $48.9 million, $45.8 million and $79.8 million in 2004, 2003 and 2002, respectively.


NOTE 7.    Income Taxes

        The Company is domiciled in Bermuda and has subsidiaries domiciled in several countries. The majority of the Company's worldwide operations are taxed in the United States. Income earned or losses incurred by non-U.S. companies will generally be subject to an overall effective tax rate lower than that imposed by the United States.

        The total income tax provision (benefit) for the years ended December 31, 2004, 2003 and 2002 consisted of the following:

 
  Year Ended December 31,

  Total income tax provision on pretax earnings   $ 47.0   $ 127.6   $ 11.7  
   
 
 
 

        Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts for tax purposes. Deferred income tax assets and liabilities are shown net in circumstances where a consolidated income

tax return is filed. An outline of the significant components of White Mountains' deferred tax assets and liabilities follows:

  Net operating loss and tax credit carryforwards   $ 102.0   $ 84.2

  Compensation and benefit accruals     219.8     180.0

Total deferred income tax assets   $ 623.8   $ 592.3
Deferred income tax liabilities related to:            
  Net unrealized investment gains     176.5     134.6
  Foreign currency translation on investments and other assets     14.4     3.8
  Equity in unconsolidated insurance affiliates     27.3     36.4

Total deferred income tax liabilities     665.3     332.3
Net deferred tax asset (liability) before valuation allowance     (41.5 )   260.0
  Valuation allowance     (3.3 )  
   
 
Net deferred tax asset (liability)   $ (44.8 ) $ 260.0
   
 

        The Company believes that it is more likely than not that results of future operations will generate sufficient taxable income to realize the deferred tax asset balances carried as of December 31, 2004 and 2003. During 2003, the valuation allowance was reduced by $30.0 million due to the expiration of certain foreign tax credits that were previously recorded as deferred tax assets. During 2004, a valuation allowance of $3.3 million was established for net operating loss carryforwards of a consolidated insurance reciprocal.

        A reconciliation of taxes calculated using the 35% U.S. statutory rate (the tax rate at which the majority of the Company's worldwide operations are taxed) to the income tax provision on pretax earnings follows:

 
  Year Ended December 31,

Total income tax provision on pretax earnings   $ 47.0   $ 127.6   $ 11.7  
   
 
 
 

        The non-U.S. component of pretax earnings was $100.0 million, $70.5 million and $97.8 million for the years ended December 31, 2004, 2003 and 2002, respectively.

        At December 31, 2004, there were U.S. net operating loss carryforwards of approximately $46.3 million available, the majority of which will expire in 2011. These tax losses are subject to an annual limitation on utilization under Internal Revenue Code Section 382. In addition, at December 31, 2004, there were Swedish net operating loss carryforwards of approximately $25.1 million available which do not expire.

        At December 31, 2004, there were credits for increasing research activities of $2.3 million which will begin to expire in 2020.

        At December 31, 2004, there were alternative minimum tax credit carryforwards available of approximately $30.8 million. The alternative minimum tax credit does not expire.

        Subsequent to the passage of the Jobs Creation Act of 2004, which extended the carryforward period for utilization of a foreign tax credit, the Company filed amended United States tax returns to claim a credit rather than a deduction for foreign taxes paid. At December 31, 2004, $45.7 million of the credit remained which will expire in 2010. During 2004, as a result of the Company's reorganization to align its legal organization with its main operating businesses, certain subsidiaries were removed from the existing consolidated Federal income tax group, resulting in $16.6 million of income tax.

        The U.S. federal income tax returns of the U.S. Companies are routinely audited by taxing authorities. In management's opinion, adequate tax liabilities have been established for all open tax years. These liabilities could be revised in the future if estimates of White Mountains' ultimate liability changes.


NOTE 8.    Retirement and Postretirement Plans

        Certain subsidiaries of the Company offer various retirement and postretirement benefits to its employees. Under the terms of these plans, White Mountains reserves the right to change, modify or discontinue the plans.

F-41



        Certain subsidiaries of the Company sponsor qualified and non-qualified, non-contributory, defined benefit plans covering substantially all employees. Current plans include a OneBeacon qualified pension plan, a OneBeacon non-qualified pension plan, and an NFU qualified pension plan. The benefits for the plans are based primarily on years of service and employees' pay near retirement. Participants generally vest after five years of continuous service. White Mountains' funding policy is consistent with the funding requirements of federal laws and regulations.

        In addition to the defined benefit plans, certain of the Company's subsidiaries have multiple contributory postretirement benefit plans which provide medical and life insurance benefits to pensioners and survivors. White Mountains' funding policy is to make contributions to the plan that are necessary to cover its current obligations.

        The majority of OneBeacon's pension and retiree medical plans were curtailed in the fourth quarter of 2002. The OneBeacon Insurance Pension Plan will no longer add new participants or increase benefits for existing participants. Non-vested participants already in the plan will continue to vest during their employment with OneBeacon, which this effectively causes the projected benefit obligation to equal the accumulated benefit obligation. Retirees are also eligible for medical benefits if they meet certain age and service requirements. However, due to the curtailment, the plan no longer accepts new retirees after a grace period ended May 31, 2003. The majority of retiree medical costs are capped at defined dollar amounts, with retirees contributing the remainder. OneBeacon uses a December 31st measurement date for its plans.

        The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the "Medicare Act") made significant changes to the federal Medicare Program by increasing coverage for prescription drugs. As a result, OneBeacon's retiree medical benefit obligations have been reduced. In the third quarter of 2004, OneBeacon adopted FASB Staff Position No. 106-2 entitled "Accounting and Disclosure Requirements Related to the Medicare Prescription Drug, Improvement and Modernization Act of 2003", which reduced OneBeacon's accumulated benefit obligation by less than $1 million. Accordingly, the impact of the Medicare Act is immaterial to White Mountains' consolidated financial position.

The discount rate in effect from January 1 through June 30, 2004 was 6.0%. The postretirement health plan was re-measured on June 30 due to plan changes that became effective on July 1. The discount rate was raised to 6.25% for the re-measurement and remained in effect through December 31, 2004.

(2)
The discount rate in effect from January 1 through June 30, 2003 was 6.5%. The postretirement health plan was re-measured on June 30 due to plan changes that became effective on July 1. The discount rate was lowered to 6.0% for the re-measurement and remained in effect through December 31, 2003.

(3)
The rate of compensation increase affects only the NFU qualified pension plan as both the OneBeacon qualified and non-qualified pensions plans are frozen.

        OneBeacon performed an analysis of expected long-term rates of return based on the allocation of its pension plan assets as of both December 31, 2004 and December 31, 2003 to develop expected rates of return for each significant asset class or economic indicator. A range of returns was developed based both on forecasts and on broad-market historical benchmarks for expected return, correlation, and volatility for each asset class. Although the expected investment return assumption is long-term in nature, the range of reasonable returns had dropped over the past few years as a consequence of lower inflation and lower bond yields.

        The assumed health care cost trend rates at December 31, 2004 and 2003 were:

 
  2004
  2003
 
Health care cost trend rate assumed for next year   10.0 % 9.5 %
Rate to which the cost trend rate is assumed to decline   5.0 % 5.0 %
Year that the rate reaches the ultimate trend rate   2014   2013  

        Assumed health care cost trend rates typically have a significant effect on the amounts reported for the health care plans. A one-percentage-point change in assumed health care cost trend rates would have the following pre-tax effects:

Total   100 % 100 %
   
 
 

        The majority of the plans' assets are invested by White Mountains Advisors LLC, a subsidiary of White Mountains Insurance Group, Ltd. The investment policy places an emphasis on preserving invested assets through a diversified portfolio of high-quality income producing investments and equity investments.

        The investment management process integrates the risks and returns available in the investment arena with the risks and returns available to the plan in establishing the proper allocation of invested assets. The asset classes include fixed income, equity, convertible securities, and cash and cash equivalents. The factors examined in establishing the appropriate investment mix include: the outlook for risk and return in the various investment markets and sectors, and the long term need for capital growth.


Cash Flows

        OneBeacon expects to contribute $4.2 million to its pension plans and $6.9 million to its other postretirement benefits plans in 2005. The majority of OneBeacon's expected pension contributions in 2005 relate to non-qualified pension plans, for which OneBeacon has established assets held in rabbi trusts.

Other Benefit Plans

        Certain of the Company's subsidiaries sponsor various employee savings plans (defined contribution plans) covering the majority of employees. The contributory plans provide qualifying employees with matching contributions of up to six percent of qualifying employees' salary (subject to federal limits on allowable contributions in a given year). Total expense for the plans was $5.8 million, $5.5 million and $7.4 million in 2004, 2003 and 2002, respectively.

F-46


        OneBeacon had a post-employment benefit liability of $13.2 million and $14.4 million related to its long-term disability plan at December 31, 2004 and 2003, respectively.

        Effective January 1, 2003, OneBeacon replaced its defined benefit pension plan with an employee stock ownership plan ("ESOP"). See Note 9.


NOTE 9. Employee Share-Based Compensation Plans

        White Mountains' share-based compensation expenses, consisting primarily of performance share expense, are designed to maximize shareholder value over long periods of time by aligning the financial interests of its management with those of its owners. The Board believes that share-based compensation for its key employees should be payable in full only if the Company achieves superior returns for its owners. White Mountains expenses all its share-based compensation, including its outstanding Options. As a result, the Company's calculation of such return includes the full expense of all outstanding share-based compensation awards.


White Mountains' Long-Term Incentive Plan (the "Incentive Plan")

        The Incentive Plan provides for granting to certain officers of the Company, and certain of its subsidiaries, various types of share-based incentive awards including performance shares, Restricted Shares and Options. The Incentive Plan was adopted by the Board and was approved by the Company's sole shareholder in 1985 and was subsequently amended by its shareholders in 1995 and 2001.

Performance Shares

        Performance shares are conditional grants of a specified maximum number of Common Shares or an equivalent amount of cash. In general, grants are earned, subject to the attainment of pre-specified performance goals, at the end of a three-year period or as otherwise determined by the Compensation Committee of the Board and are valued based on the market value of Common Shares at the time awards are paid. Results that significantly exceed pre-specified targets can result in a performance share payout of up to 200% of value whereas results significantly below target result in no payout. The Company's principal performance share goal is its after-tax corporate return on equity as measured by growth in its intrinsic value per share ("ROE"). The Company calculates intrinsic value per share based on its growth in economic value per share (weighted 50%), growth in tangible GAAP book value per share (weighted 25%) and growth in market value per share (weighted 25%).This proprietary measure is viewed by management and the Board as being an objective and conservative measure of the value of White Mountains and includes the projected cost of all outstanding compensation awards. At December 31, 2004, 69,250, 75,200 and 53,500 performance shares had been granted at target under the Incentive Plan for the three-year performance periods beginning 2004, 2003 and 2002, respectively.

        During 2004, White Mountains made payments with respect to 63,480 performance shares (relating to the 2001-2003 performance period) at an average 137% payout level, amounting to $40.7 million, to its participants in cash or by deferral into certain non-qualified compensation plans of the Company or its subsidiaries. During the first quarter of 2003, White Mountains made payments with respect to 39,500 performance shares (relating to the 2000-2002 performance period) at a 200% payout level, amounting to $25.7 million, to its participants in cash or by deferral into certain non-qualified compensation plans of the Company or its subsidiaries. In the second quarter of 2003, White Mountains made payments with respect to 21,725 performance shares, amounting to $13.1 million, in cash or by deferral into certain non-qualified compensation plans of the Company. The performance share payments in the second quarter were the result of an agreed upon cancellation of performance shares held by certain non-employee directors of the Company for performance periods scheduled to end on December 31, 2003, 2004 and 2005. During 2002, White Mountains paid a total of 31,300 performance shares (relating to the 1999-2001 performance period) at a 200% value, amounting to

F-47



$20.7 million, to its participants in cash, Common Shares or by deferral into certain non-qualified compensation plans of the Company or its subsidiaries.

        The targeted performance goal for full payment of performance shares granted during 2004 to non-investment personnel is the attainment of an ROE of 13%. At an ROE of 6% or less, no such performance shares would be earned and at an ROE of 20% or more, 200% of such performance shares would be earned. With respect to the 2004 performance shares granted investment personnel, the performance goals for full payment are based in part on the ROE criteria described above and in part on the attainment of an annual return on invested assets of the greater of 1.5% or 150 basis points over the applicable total return on the constant maturity ten-year United States treasury note (the "2004 Treasury Return"). At an annual return on invested assets less than or equal to the greater of 0% or the 2004 Treasury Return, no such performance shares would be earned and at an annual return on invested assets of the greater of 3.25% or 325 basis points over the 2004 Treasury Return, 200% of such performance shares would be earned. With respect to the 2004 performance shares granted to investment personnel, the Compensation Committee of the Board generally retains the authority to weigh each performance goal as they deem appropriate at the end of the cycle.

        The targeted performance goal for full payment of performance shares granted during 2003 to non-investment personnel is the attainment of an ROE of 11%. At an ROE of 4% or less, no such performance shares would be earned and at an ROE of 21% or more, 200% of such performance shares would be earned. With respect to the 2003 performance shares granted to investment personnel, the performance goals for full payment are based in part on the ROE criteria described above and in part on the attainment of an annual return on invested assets of 150 basis points over the applicable total return on the constant maturity ten-year United States treasury note (the "2003 Treasury Return"). At an annual return on invested assets equal to the 2003 Treasury Return, no such performance shares would be earned and at an annual return on invested assets of 325 basis points over the 2003 Treasury Return, 200% of such performance shares would be earned. With respect to the 2003 performance shares granted to investment personnel, the Compensation Committee of the Board generally retains the authority to weigh each performance goal as they deem appropriate at the end of the cycle.

        The targeted performance goal for full payment of performance shares granted during 2002 to certain holding company personnel is based on the attainment of an ROE of 12%. At an ROE of 5% or less, no such performance shares would be earned and at an ROE of 23% or more, 200% of such performance shares would be earned. With respect to the 2002 performance shares granted to OneBeacon personnel (including certain officers of the holding company), the targeted performance goal for full payment is based in part on the ROE criteria described above and in part on the attainment of an insurance trade ratio of 102% on OneBeacon's core insurance operations. At a trade ratio of 106% or more, no such performance shares would be earned and at a trade ratio of 96% or less, 200% of such performance shares would be earned. With respect to the 2002 performance shares granted to investment personnel, the performance goals for full payment are based in part on the ROE criteria described above and in part on the attainment of an annual return on invested assets of 150 basis points over the applicable total return on the constant maturity ten-year United States treasury note (the "2002 Treasury Return"). At an annual return on invested assets equal to the 2002 Treasury Return, no such performance shares would be earned and at an annual return on invested assets of 300 basis points over the 2002 Treasury Return, 200% of such performance shares would be earned. With respect to the 2002 performance shares granted to OneBeacon personnel (including certain officers of the holding company) and investment personnel, in general the Compensation Committee of the Board generally retains the authority to weigh each performance goal as they deem appropriate at the end of the cycle.

Restricted Shares

        In 2001 White Mountains' Compensation Committee issued 94,500 Restricted Shares, of which 21,000 vested in December, 2002 and 73,500 vested in June 2003. During 2002 and 2003, the Company repurchased 20,750 and 34,000, respectively, of these Restricted Shares and in return granted an equivalent value in various non-qualified deferred compensation plans of the Company and its subsidiaries. During 2004 and 2003, certain key officers were awarded 10,000 and 6,000 Restricted Shares, respectively. No Restricted Shares were awarded during 2002. These Restricted Shares vest either ratably or entirely over a three year period from the date of grant and vesting of Restricted Share awards is dependent on continuous service by the employee throughout the award period. There are no other restrictions on the Restricted Shares once they have become fully vested. As of December 31, 2004, the Company had 15,000 Restricted Shares that were unvested.

Options

        At December 31, 2004 and 2003, the Company had 46,530 Options outstanding (10,530 of which were exercisable) and 50,565 Options outstanding (7,365 of which were exercisable), respectively. These Options were issued in 2000 to certain key employees as a one-time incentive and vest ratably over a ten-year period. The Options had a weighted average exercise price of $140.80 and $132.83 per Common Share at December 31, 2004 and 2003, respectively. During 2004 and 2003, 4,035 and 11,400 Options, respectively, were exercised at an average exercise price of $139.58 and $129.01 per Common Share, respectively.


OneBeacon Performance Plan

        OneBeacon's Performance Plan (the "OB Performance Plan") provides for granting of performance shares to certain key employees of OneBeacon. The performance goals for full payment of performance shares issued under the OB Performance Plan are similar to those of the Incentive Plan. The OB Performance Plan was approved by the Board but was not subject to shareholder approval.

        At December 31, 2004, there were 3,500, none and 150,896 performance shares outstanding under the OB Performance Plan for the three-year performance periods beginning 2004, 2003 and 2002, respectively. During 2004, OneBeacon made payments with respect to 101,802 performance shares (relating to the 2001-2003 performance period) at an average 182% payout level, amounting to $84.6 million, to its participants in cash. No performance shares were paid during 2003 and 2002.


Folksamerica Performance Plan

        Folksamerica's Performance Plan provides for granting of performance shares to certain key employees of Folksamerica. The performance goals for full payment of performance shares issued under the Folksamerica Performance Plan are similar to those of the Incentive Plan. The Folksamerica Performance Plan was approved by the Board but was not subject to shareholder approval.

        At December 31, 2004, there were 2,000, 4,900 and 9,400 performance shares outstanding under the Folksamerica Performance Plan for the three-year performance periods beginning 2004, 2003 and 2002, respectively. Folksamerica made payments with respect to 2,500 performance shares (relating to the 2001-2003 performance period) at a 93% payout level, amounting to $1.1 million, to its participants in cash. Folksamerica made payments with respect to 5,500 performance shares (relating to the 2000-2002 performance period) at a 200% payout level, amounting to $2.9 million, to its participants in cash. No performance shares were paid during 2002.


Other Share-Based Compensation

        The defined contribution plans of OneBeacon and Folksamerica (the "401(k) Plans") offer its participants the ability to invest their balances in several different investment options, including the

F-49



Company's Common Shares. As of December 31, 2004 and 2003, the 401(k) Plans owned less than 1% of the total Common Shares outstanding. In connection with the OneBeacon Acquisition, during 2001 eligible OneBeacon employees received a one-time contribution of two Common Shares which resulted in the issuance of 11,980 Common Shares.

        Effective January 1, 2003, OneBeacon adopted an employee stock ownership plan ("ESOP"), which is a OneBeacon-funded benefit plan. The ESOP provides all of its participants with an annual base contribution in Common Shares equal to 3% of their salary, up to the applicable Social Security wage base (or $87,900 with respect to 2004). Additionally, those participants not otherwise eligible to receive benefits under OneBeacon's Management Incentive Plan can earn up to an additional 6% of their salary through the ESOP, contingent upon OneBeacon's performance. OneBeacon accrued $13.3 million to pay benefits and allocate shares of stock to participant's accounts in the first quarter of 2005 and paid $13.2 million in benefits to allocate shares of stock to participant's accounts during the first quarter of 2004.


NOTE 10. Mandatorily Redeemable Preferred Stock of Subsidiaries and Convertible Preference Shares

Mandatorily Redeemable Preferred Stock

        In July 2003, White Mountains adopted the provisions of SFAS 150 and it subsequently adopted FSP 150-3 in November 2003 (See Note 1). White Mountains has two classes of mandatorily redeemable preferred stock of subsidiaries, which were previously classified as minority interests, that fell within the scope of SFAS 150 and are considered noncontrolling interests under FSP 150-3. Upon adoption of SFAS 150 in 2003, White Mountains reclassified these instruments from mezzanine equity to liabilities at their historical carrying values. In addition, beginning in the third quarter of 2003, all dividends and accretion on White Mountains' mandatorily redeemable preferred stock have been recorded as interest expense. During the years ended December 31, 2004 and 2003 White Mountains recorded $47.6 million and $22.3 million, respectively as interest expense on preferred stock (of which $17.3 million and $7.2 million, respectively, represented accretion of discount).

Berkshire Preferred Stock

        As part of the financing for the OneBeacon Acquisition, Berkshire invested a total of $300 million in cash, of which (i) $225 million was for the purchase of the Berkshire Preferred Stock, which has a $300 million redemption value; and (ii) $75 million was for the purchase of the Warrants. The Berkshire Preferred Stock is entitled to a dividend of no less than 2.35% per quarter and is mandatorily redeemable on May 31, 2008. The Berkshire Preferred Stock was initially recorded at $145.2 million, as the aggregate proceeds received from Berkshire of $300 million were originally between the Berkshire Preferred Stock and the Warrants, based on their relative fair values in accordance with Accounting Principles Board Opinion No. 14, "Accounting for Convertible Debt and Debt Issued with Stock Purchase Warrants". Through December 31, 2004, the carrying value of the Berkshire Preferred Stock had been accreted up to $191.9 million.

        During each of 2004, 2003 and 2002, White Mountains declared and paid dividends of $28.2 million on the Berkshire Preferred Stock and recorded $17.3 million, $13.6 million and $10.6 million, respectively, of related accretion charges. In accordance with SFAS 150, $28.2 million and $14.1 million, respectively of the dividends and $17.3 million and $7.2 million, respectively of the accretion recorded during the year ended December 31, 2004 and during the second half of 2003 are presented as interest expense on mandatorily redeemable preferred stock.

Zenith Preferred Stock

        On June 1, 2001, Zenith Insurance Company ("Zenith") purchased $20.0 million in cumulative non-voting preferred stock of a subsidiary of the Company (the "Zenith Preferred Stock"). The Zenith

F-50



Preferred Stock is entitled to a dividend of no less than a 2.5% per quarter through June 30, 2007 and a dividend of no less than 3.5% per quarter thereafter and is mandatorily redeemable on May 31, 2011. At the Company's option, the Zenith Preferred Stock may be redeemed on June 30, 2007. During 2004, 2003 and 2002, White Mountains declared and paid dividends of $2.0 million, $2.0 million and $2.1 million, respectively, on the Zenith Preferred Stock. In accordance with SFAS 150, $2.0 million and $1.0 million, respectively of the dividends recorded during the year ended December 31, 2004 and during the second half of 2003 are presented as interest expense on mandatorily redeemable preferred stock.

Convertible Preference Shares

        In October of 2002, White Mountains sold $200.0 million of convertible preference shares in a private transaction. Investment funds managed by Franklin Mutual Advisers, LLC purchased 677,966 convertible preference shares of the Company at a price of $200.0 million ($295.00 per share). Upon shareholder approval at the Company's Annual Meeting held on May 19, 2003, the convertible preference shares were repurchased and cancelled in consideration of 677,966 Common Shares. Because the redemption value of the convertible preference shares was in excess of the cash received upon their issuance, they were required to be marked-to-market until the date they were converted to shareholders' equity, resulting in a cumulative $68.5 million charge to retained earnings ($49.5 million of which was recognized during the year ended December 31, 2003), with an offsetting increase to paid-in surplus.


NOTE 11. Common Shareholders' Equity

Common Shares repurchased and retired

        During 2004, 2003 and 2002, the Company repurchased for cash 97 Common Shares for $.1 million, 284 Common Shares for $.1 million and 489 Common Shares for $.2 million respectively. In addition, during 2004, 2003 and 2002 the Company repurchased 316, 39,274 and 20,750, respectively, outstanding Restricted Shares held by certain key employees who were instead granted the market value of such shares in various non-qualified deferred compensation plans of the Company and its subsidiaries (See Note 9). In conformance with Bermuda law, the Company retires all Common Shares it repurchases.

Common Shares issued

        On June 29, 2004, Berkshire exercised all of its warrants to purchase 1,724,200 Common Shares of White Mountains for $294 million. As a result, Berkshire now holds approximately 16.0% of White Mountains' outstanding common stock. Berkshire acquired the warrants in connection with the financing of White Mountains' acquisition of OneBeacon in 2001. The warrants were exercisable at any time until May 2008 and callable by the Company on or after May 31, 2005. In consideration for the early exercise of the warrants, Berkshire and the Company agreed to reduce the exercise price by approximately 2%.

        In addition to the Berkshire warrant exercise, during the year ended December 31, 2004, the Company issued a total of 41,807 Common Shares, which consisted of 27,772 shares issued to the OneBeacon employee stock ownership plan, 10,000 Restricted Shares issued to key management personnel, and 4,035 shares issued in satisfaction of Options exercised. During 2003, the Company issued a total of 695,366 Common Shares, which consisted of 677,966 Common Shares issued in connection with the repurchase and cancellation of Convertible Preference Shares and 17,400 Common Shares issued to employees in connection with various White Mountains share-based compensation plans. During 2002, the Company issued a total of 107,945 Common Shares, which consisted of 84,745 Common Shares issued in a private equity transaction with Highfields for $25.0 million ($295.00 per

F-51



Common Share) and 23,200 Common Shares issued to employees in connection with various White Mountains share-based compensation plans.

Dividends on Common Shares

        During 2004, 2003 and 2002, the Company declared and paid cash dividends totalling $9.1 million (or $1.00 per Common Share), $8.3 million (or $1.00 per Common Share) and $8.3 million (or $1.00 per Common Share), respectively.


NOTE 12. Statutory Capital and Surplus

        White Mountains' insurance and reinsurance operations are subject to regulation and supervision in each of the jurisdictions where they are domiciled and licensed to conduct business. Generally, regulatory authorities have broad supervisory and administrative powers over such matters as licenses, standards of solvency, premium rates, policy forms, investments, security deposits, methods of accounting, form and content of financial statements, reserves for unpaid loss and LAE, reinsurance, minimum capital and surplus requirements, dividends and other distributions to shareholders, periodic examinations and annual and other report filings. In general, such regulation is for the protection of policyholders rather than shareholders. Over the last several years most states have implemented laws that establish standards for current, as well as continued, state accreditation. In addition, the NAIC uses risk-based capital ("RBC") standards for property and casualty insurers as a means of monitoring certain aspects affecting the overall financial condition of insurance companies. At December 31, 2004, White Mountains' active insurance and reinsurance operating subsidiaries met their respective RBC requirements.

        OneBeacon's consolidated combined policyholders' surplus (which includes Folksamerica and its subsidiaries at December 31, 2003), as reported to various regulatory authorities as of December 31, 2004 and 2003, was $1,773.4 million and $2,810.8 million, respectively. OneBeacon's consolidated combined statutory net income (loss) for the years ended December 31, 2004, 2003 and 2002 was $314.2 million, $472.1 million and $342.6 million, respectively. The principal differences between OneBeacon's combined statutory amounts and the amounts reported in accordance with GAAP include deferred acquisition costs, deferred taxes, gains recognized under retroactive reinsurance contracts, market value adjustments for debt securities and recognition of pension plan curtailment gains. OneBeacon's insurance subsidiaries' statutory policyholders' surplus at December 31, 2004 was in excess of the minimum requirements of relevant state insurance regulations.

        Folksamerica Reinsurance Company's, ("Folksamerica Re") policyholders' surplus, as reported to various regulatory authorities as of December 31, 2004 and 2003, was $917.4 million and $912.8 million, respectively. Folksamerica Re's statutory net income (loss) for the years ended December 31, 2004, 2003 and 2002 was $(1.0) million, $33.0 million and $58.2 million, respectively. The principal differences between Folksamerica Re's statutory amounts and the amounts reported in accordance with GAAP include deferred acquisition costs, deferred taxes, gains recognized under retroactive reinsurance contracts and market value adjustments for debt securities. Folksamerica Re's statutory policyholders' surplus at December 31, 2004 was in excess of the minimum requirements of relevant state insurance regulations.

        Under the insurance laws of the jurisdictions under which White Mountains' regulated insurance operating subsidiaries are domiciled, an insurer is restricted with respect to the timing and the amount of dividends it may pay without prior approval by regulatory authorities. Accordingly, there can be no assurance regarding the amount of such dividends that may be paid by such subsidiaries in the future. Following is a description of the ability of White Mountains insurance and reinsurance operating

F-52



subsidiaries to make pay dividends during 2005 to the Company, and certain of its intermediate holding companies:

        Generally, OneBeacon's regulated insurance operating subsidiaries have the ability to pay dividends during any 12 month period without the prior approval of regulatory authorities in an amount equal to the greater of prior year statutory net income or 10% of prior year end statutory surplus, subject to the availability of unassigned funds. As a result, based upon 2004 statutory net income OneBeacon's top tier regulated insurance operating subsidiaries have the ability to pay $325.2 million of dividends during 2005 without prior approval of regulatory authorities, subject to the availability of unassigned funds. As of December 31, 2004, OneBeacon's top tier regulated insurance operating subsidiaries had $1.3 billion of unassigned funds available for dividend distribution. In addition, as of December 31, 2004, OneBeacon had $195.0 million of cash and investments outside of its regulated insurance operating subsidies available for distribution during 2005. During 2004, OneBeacon paid $305 million of cash dividends to Fund American.

        Folksamerica Re has the ability to pay dividends during any 12 month period without the prior approval of regulatory authorities in an amount equal to the lesser of net investment income, as defined by statute, or 10% of statutory surplus, in both cases as most recently reported to regulatory authorities, subject to the availability of earned surplus. As a result, based upon December 31, 2004 statutory surplus of $917.4 million, Folksamerica Re would have the ability to pay approximately $91.7 million of dividends during 2005 without prior approval of regulatory authorities, subject to the availability of earned surplus. As of December 31, 2004, Folksamerica Re had $16.8 million of earned surplus, therefore it can pay dividends of $16.8 million plus additional earned surplus reported during 2005, subject to the $91.7 million limitation discussed above.

        As of December 31, 2004, WMU had $3.2 million of cash and investments available for distribution during 2005. In addition, WMU has the ability to distribute its 2005 earnings without restriction. During 2004, WMU paid $60.0 million of cash dividends to its immediate parent.

        In addition, as of December 31, 2004, White Mountains Re had approximately $97 million of cash and investments outside of its regulated insurance and reinsurance operating subsidiaries available for distribution during 2005.

        In accordance with Swedish regulations, Sirius International holds restricted reserves of $808.1 million, which represents 72% of its untaxed reserves (See Liquidity and Capital Resources within the Management Discussion and Analysis for information). These restrictions are based on stockholder's equity determined on a Swedish statutory basis. These restricted reserves can not be paid as dividends. At December 31, 2004 Sirius International is in compliance with these restrictions. Sirius International's actual statutory surplus at December 31, 2004, which includes Scandinavian Re and its other subsidiaries is $1.3 billion.

Safety Reserve

        In accordance with provisions of Swedish law, Sirius International can voluntarily transfer its pretax earnings, or a portion thereof, subject to certain limitations, into an untaxed reserve referred to as a safety reserve. The safety reserve is a Swedish regulatory concept that has no equivalent under GAAP. Accordingly, under GAAP, an amount equal to Sirius International's safety reserve of $1.1 billion at December 31, 2004, net of the related deferred tax liability established at the statutory Swedish tax rate of 28%, is classified as equity. Generally, this deferred tax liability is only required to be paid by Sirius International if it fails to maintain predetermined levels of premium writings in future years. As a result of the indefinite deferral of these taxes, Swedish regulatory authorities do not apply any taxes to the safety reserve when calculating solvency capital under Swedish insurance regulations.

NOTE 14. Investments in Unconsolidated Insurance Affiliates

        White Mountains' investments in unconsolidated insurance affiliates represent operating investments in other insurers in which White Mountains has a significant voting and economic interest but does not own more than 50.0% of the entity. White Mountains' voting percentages and directorships in its unconsolidated affiliates do not provide White Mountains the ability to exercise significant influence over the operating and financial policies of its investees.

Investment in Symetra

        On August 2, 2004, White Mountains invested $194.7 million in Symetra in exchange for 2.0 million common shares and 1.1 million warrants to purchase additional common shares of Symetra (See Note 2). As of December 31, 2004, White Mountains owned 19% of the total of Symetra's common shares outstanding and 24% of Symetra's common shares on a fully-diluted basis. White Mountains accounts for its investment in Symetra's common shares using the equity method, while it accounts for its investment in Symetra' warrants as a derivative instrument, recognizing changes in the fair value of the warrants through the income statement as a realized gain or loss.

Investment in Montpelier

        As of December 31, 2004, White Mountains' investment in Montpelier consisted of 6.3 million common shares and warrants to acquire 7.2 million common shares at $16.67 per share that are exercisable until December 6, 2011. Through its holdings of common shares and warrants, White Mountains owns approximately 17% of Montpelier on a fully-converted basis.

        During the first quarter of 2004, White Mountains sold a portion of its investment in Montpelier common shares to third parties. As a result of this sale, as well as changes to the composition of the

F-58



Board of Directors of both Montpelier and White Mountains, White Mountains changed the method of accounting for its remaining common share investment in Montpelier as of March 31, 2004 from an equity method investment in an unconsolidated affiliate to a common equity security classified as available for sale and carried at fair value. White Mountains accounts for its warrants in Montpelier as derivative instruments and recognizes changes in the fair value of the warrants during a given period in its income statement as a realized gain or loss. (See Note 5 for details of White Mountains' investment in Montpelier as of December 31, 2004).

        White Mountains' equity in earnings of Montpelier was $10.8 million, $45.1 million and $19.9 million (net of tax of $6.1 million, $24.4 million and $10.7 million) for the years ended 2004, 2003 and 2002, respectively.


Note 15. Variable Interest Entities

New Jersey Skylands

        As part of a restructuring of its New Jersey personal lines, OneBeacon formed New Jersey Skylands Management LLC and the New Jersey Insurance Department approved the formation of New Jersey Skylands Insurance Association and its wholly owned subsidiary New Jersey Skylands Insurance Company (together, the "Association") during the third quarter of 2002. New Jersey Skylands Insurance Association (the "NJ Skylands Reciprocal"), is a not-for-profit, policyholder-owned reciprocal insurance carrier. A reciprocal is an unincorporated association with each insured sharing risk with the others in the association. Thus, each participant in this pool is both an insurer and an insured. Policyholders share profits and losses in the same proportion as the amount of insurance purchased by that member. However, policyholders in the reciprocal are not subject to assessment for losses of the reciprocal.

        An attorney-in-fact administers the reciprocal. Such administration entails paying losses, investing premium inflow, recruiting new members, underwriting new and renewal business, receiving premiums and exchanging reinsurance contracts. New Jersey Skylands Management LLC is the attorney-in-fact for all the business affairs of the NJ Skylands Reciprocal. Accordingly, New Jersey Skylands Insurance Company, the stock insurance company, has a management agreement with New Jersey Skylands Management LLC to manage its business affairs.

        The NJ Skylands Reciprocal was capitalized by OneBeacon with a $31.3 million surplus note. Principal and interest on the surplus note are repayable only with regulatory approval. As defined in the surplus note agreement, the NJ Skylands Reciprocal's obligation to pay principal under the surplus note agreement is subordinated to all liabilities and obligations to policyholders, to claimants for benefits under contracts of insurance it issued, to all other classes of creditors other than surplus note holders, and to the State of New Jersey and any governmental or quasi-governmental entity. The Association began writing personal automobile coverage for new customers in August 2002.

        OneBeacon has no ownership interest in the Association. As a result of its adoption of FIN 46, White Mountains' future economic income derived from the New Jersey automobile insurance market will differ from the operating results that it will record on a consolidated GAAP basis. On an economic basis, OneBeacon will realize income from management and service fees charged by New Jersey Skylands Management LLC to the Association and interest on the surplus note. On a consolidated GAAP basis, White Mountains will recognize profits from the insurance operations of the Association until such time that the Association's equity is greater than zero or until the accumulated losses in the Association exceed OneBeacon's initial surplus note investment. White Mountains has determined that the Association qualifies as a VIE under the provisions of FIN 46. Upon adoption of FIN 46 on March 31, 2004, White Mountains consolidated the Association, which had total assets and total liabilities with a carrying value of $138.5 million and $111.6 million, respectively. The resulting $26.9 million difference between the carrying values of the total assets and liabilities of the Association was equal to the March 31, 2004 carrying value of the surplus note investment at OneBeacon. Therefore, the adoption of FIN 46 did not have an effect on the Company's financial condition. The Company's exposure to the New Jersey auto market remains limited to the surplus notes invested in the reciprocal.

Prospector Offshore Fund

        White Mountains has determined that one of its ownership interests in a limited partnership, Prospector Offshore Fund, Ltd. ("the Fund"), qualifies as a VIE under the provisions of FIN 46. The Company's economic exposure to the Fund is equal to $51.1 million, which represents the Company's 49.3% ownership in the Fund's total equity. Any creditor of the Fund would not have recourse against the Company beyond the Company's investment.


NOTE 16. Fair Value of Financial Instruments

        SFAS No. 107, "Disclosure about Fair Value of Financial Instruments" ("SFAS 107"), requires disclosure of fair value information of financial instruments. For certain financial instruments where quoted market prices are not available, other independent valuation techniques and assumptions are used. Because considerable judgment is used, these estimates are not necessarily indicative of amounts that could be realized in a current market exchange. SFAS 107 excludes certain financial instruments from disclosure, including insurance contracts, other than financial guarantees and investment contracts. White Mountains carries its financial instruments on its balance sheet at fair value with the exception of its fixed-rate, long-term indebtedness.

        At December 31, 2004 and 2003, the fair value of White Mountains' Senior Notes (its only fixed-rate, long-term indebtedness) was $714.0 million and $710.6 million respectively, which compared to a carrying value of $698.3 million and $698.1 million, respectively.

        At December 31, 2004, the fair values of the Berkshire and Zenith Preferred Stock were $340.5 million and $22.7 million, respectively, which compared to carrying values of $191.9 million and $20.0 million, respectively.

        The fair values of these obligations were estimated by discounting future cash flows using current market rates for similar obligations or using quoted market prices. Considerable judgment is required to develop such estimates of fair value. Therefore, the estimate provided herein is not necessarily indicative of the amounts that could be realized in a current market exchange.


NOTE 17. Related Party Disclosures

Berkshire

        Berkshire owned approximately 16% of the Common Shares of White Mountains as of December 31, 2004. Berkshire acquired the Common Shares through its June 2004 exercise of warrants to purchase 1,724,200 Common Shares for $294 million. Berkshire bought the warrants in connection with the financing of White Mountains' acquisition of OneBeacon in 2001. The warrants were exercisable at any time until May 2008 and callable by the Company on or after May 31, 2005. Berkshire and the Company agreed to reduce the exercise price by approximately 2% ($6 million) to induce Berkshire's early exercise of the warrants.

        In November 2004, White Mountains completed a significant corporate reorganization that made the legal organization of White Mountains' subsidiaries consistent with its main operating businesses. In order to effect the reorganization, White Mountains and Fund American entered into or amended certain agreements with respect to the Series A Preferred Stock of Fund American (the "Series A Preferred Stock"), which is owned by subsidiaries of Berkshire. Under the terms of a Keep-Well Agreement dated November 30, 2004 between White Mountains and Fund American (the "Keep-Well"), White Mountains has agreed to return to Fund American up to approximately $1.1 billion, which equals the amount of net assets transferred out of Fund American as a result of the reorganization, if some or all of that amount is required by Fund American to meet its obligations to Berkshire under the Series A Preferred Stock. Additionally, the Keep-Well limits the aggregate amount of distributions that White Mountains may make to its shareholders to approximately $1.3 billion plus

F-60



White Mountains' aggregate consolidated net income after September 30, 2004. The Keep-Well will expire when all obligations of the Series A Preferred Stock, which is redeemable in May 2008, have been satisfied, or when approximately $1.1 billion has been returned to Fund American.

        NICO and GRC, which have provided the NICO Cover and the GRC Cover to subsidiaries of White Mountains, are wholly-owned subsidiaries of Berkshire (see Note 4). Reinsurance recoverable from, and preferred stock of White Mountains' subsidiaries owned by, Berkshire are shown as separate line items in White Mountains' consolidated balance sheet. In addition, in the ordinary course of its business, White Mountains has, and in the future may, enter into other insurance and reinsurance transactions with Berkshire on arm's length terms and conditions.

        White Mountains and Berkshire co-led the investor group that acquired Symetra for $1.35 billion on August 2, 2004. See "Symetra" below.


Olympus

        Folksamerica and Sirius have entered into quota share retrocessional arrangements with Olympus. Under these arrangements with Olympus, Folksamerica ceded up to 75% of substantially all of its short-tailed excess of loss business, mainly property and marine, and 50% of its proportional property business to Olympus and received an override commission on the premiums ceded to Olympus. Effective April 1, 2004, Sirius International entered into a quota share reinsurance agreement with Olympus. Under this agreement, Sirius International ceded 25% of its new and renewal short-tailed proportional and excess of loss business to Olympus. During 2004, 2003 and 2002, White Mountains ceded $465.6 million, $449.1 million and $229.7 million, respectively, in written premiums and $269.5 million, $107.0 million and $54.4 million, respectively, in losses and LAE to Olympus. White Mountains receives fee income on reinsurance placements referred to Olympus and is entitled to additional fees based on net underwriting profits on referred business. During 2004, 2003 and 2002, White Mountains earned $68.7 million, $98.4 million and $48.9 million of fee income from Olympus. White Mountains does not own or control any common shares of Olympus Holdings.

        Joseph Steinberg, a director of the Company, is Chairman of Olympus Holdings (the parent company of Olympus) and is President of Leucadia.

Lehman has, from time to time, provided various services to White Mountains including investment banking services, brokerage services, underwriting of debt and equity securities and financial consulting services. Lehman was the lead underwriter of Fund American's $700.0 million Senior Notes. Lehman was also the arranger, the administrative agent and a lender under the Old Bank Facility and is a lender under White Mountains' current Bank Facility. See Note 6.

        George Gillespie, a director and Chairman of the Company, is a Partner at Cravath, Swaine & Moore LLP ("CS&M"), which has been retained by White Mountains from time to time to perform legal services.

        John Gillespie, pursuant to his employment agreement entered into with the Company as of January 1, 2001, may continue his active involvement with Prospector so long as he devotes the requisite time required to fulfill his responsibilities to WM Advisors. The agreement specifies procedures pursuant to which Prospector's funds have the ability to invest first in opportunities generated by Mr. Gillespie that are appropriate for both White Mountains and such funds. In addition, pursuant to a revenue sharing agreement established in connection with his employment by the Company, Mr. Gillespie has agreed to pay White Mountains 33% of certain revenues of Prospector in return for White Mountains agreeing to pay its operational expenses. For 2004, White Mountains' received total revenues of approximately $4.2 million and paid total expenses of approximately $2.8 million under the revenue sharing agreement. Pursuant to another revenue sharing agreement with Prospector, Mr. Gillespie has agreed to pay White Mountains 6% of the revenues in excess of $500,000 of certain of Prospector's funds in return for White Mountains having made a founding investment in Prospector in 1997.

        In September 2001, White Mountains Advisors entered into a five-year lease at a market-based rate for a building partially owned by John Gillespie and trusts for the benefit of members of his family (the "Gillespie Trusts"). For 2004, the rental payments attributable to John Gillespie's ownership in the building totalled approximately $16,000 and the rental payments attributable to the Gillespie Trusts' ownership in the building totalled approximately $127,000.

        John Gillespie indirectly through general and limited partnership interests holds a 44% interest in Dowling & Partners Connecticut Fund III, LP ("Fund III"). OBPP and Folksamerica Specialty Underwriting, Inc. ("FSUI") have borrowed approximately $8 million and $7 million, respectively, from Fund III in connection with an incentive program sponsored by the State of Connecticut known as the Connecticut Insurance Reinvestment Act (the "CIR Act"). The CIR Act provides for Connecticut income tax credits to be granted for qualifying investments made by approved fund managers. The loans made by Fund III to OBPP and FSUI are qualifying investments and, together, have the potential to generate up to $15 million of tax credits that would be shared equally between Fund III on the one

F-62



hand and OBPP and FSUI on the other. As a result of his interest in Fund III, John Gillespie could realize up to $3.3 million from the tax credits, although any such amount would be subject to the revenue sharing agreements with White Mountains described above.

NOTE 18. Commitments and Contingencies

        White Mountains leases certain office space under noncancellable operating leases expiring at various dates through 2010. Rental expense for all of White Mountains' locations was approximately $46.5 million, $42.9 million and $45.9 million for the years ended December 31, 2004, 2003 and 2002, respectively. White Mountains also has various other lease obligations which are immaterial in the aggregate.

        White Mountains' future annual minimum rental payments required under noncancellable leases for office space are $41.8 million, $37.7 million, $34.1 million, $26.3 million and $28.6 million for 2005, 2006, 2007, 2008 and 2009 and thereafter, respectively.

Assigned Risks

        As a condition of its license to do business in certain states, White Mountains' insurance operations are required to participate in mandatory shared market mechanisms. Each state dictates the types of insurance and the level of coverage that must be provided. The total amount of such business an insurer is required to accept is based on its market share of voluntary business in the state. In certain cases, White Mountains is obligated to write business from mandatory shared market mechanisms at some time in the future based on the market share of voluntary policies it is currently writing. Underwriting results related to assigned risk plans are typically adverse and are not subject to the predictability associated with White Mountains' voluntarily written business.

        Under existing guaranty fund laws in all states, insurers licensed to do business in those states can be assessed for certain obligations of insolvent insurance companies to policyholders and claimants. In accordance with SOP 97-3, White Mountains' insurance subsidiaries record guaranty fund assessments when such assessments are billed by the respective guaranty funds. In addition, each insurance subsidiary's policy is to accrue for any significant insolvencies when the loss is probable and the assessment amount can be reasonably estimated. The actual amount of such assessments will depend upon the final outcome of rehabilitation proceedings and will be paid over several years. At December 31, 2004, the reserve for such assessments at White Mountains' insurance subsidiaries totalled $18.3 million.

General Litigation

        White Mountains, and the insurance and reinsurance industry in general, are subject to litigation and arbitration in the normal course of its business. Other than those items listed below, White Mountains was not a party to any material litigation or arbitration other than as routinely encountered in claims activity, none of which is expected by management to have a material adverse effect on its financial condition and/or cash flows as of December 31, 2004.

F-63



        On May 15, 2002, The Robert Plan Corporation and several of its subsidiaries filed a lawsuit against the Company, certain of its subsidiaries and several individuals employed by such subsidiaries. The suit alleges that the defendants misappropriated confidential information of the plaintiffs and used such information to enter into the New York automobile assigned risk business in direct competition with the plaintiffs. The plaintiffs seek approximately $185 million in damages which they allege represents two years of their lost profits in the subject business. The Company, its named subsidiaries and its named employees do not believe they engaged in any improper or actionable conduct. White Mountains and its subsidiaries have no reason to believe they have any liability to The Robert Plan Corporation and intend to vigorously defend the lawsuit. In addition, OneBeacon has brought a counterclaim against the plaintiffs that it believes to be meritorious. OneBeacon is seeking compensatory damages of $8.8 million as a result of the breach by the plaintiffs of the LAD servicing contract that OneBeacon had entered into with them.

        In December 2001, American Centennial filed for arbitration against Gerling, a reinsurer of American Centennial, based on Gerling's failure to pay American Centennial amounts due under a reinsurance contract. Gerling had requested the arbitration panel to rescind the contract as of December 31, 2000 based upon, among other things, White Mountains' acquisition of American Centennial in 1999. A preliminary judgement was handed down in December 2003 in which the arbitrator ruled that Gerling had been harmed and they are entitled to a discount on certain amounts that it owes American Centennial under the contract. The impact of this discount is immaterial to White Mountains' financial results. A final judgement handed down in January 2004 confirmed that the reinsurance contract will remain in-force. At December 31, 2003, American Centennial had recorded $22.7 million in recoverables from Gerling under this reinsurance contract, of which $9.8 million was for losses paid by American Centennial. Gerling has subsequently reimbursed American Centennial early in 2004 for the $9.8 million in paid recoverables. The remaining obligation on unpaid recoverables is fully collateralized.

        In August 2000, Aramarine, a former insurance broker of OneBeacon's, filed a lawsuit alleging that OneBeacon had wrongfully terminated its business relationship with Aramarine. The suit originally claimed $410 million in compensatory damages for lost commissions. However, Aramarine has recently reduced its demand to $158 million. OneBeacon does not believe it has engaged in any actionable conduct. During 2004, OneBeacon prevailed on a motion for summary judgment to dismiss the plaintiff's claim. OneBeacon expects the plaintiff to appeal the summary judgment upon resolution of OneBeacon's counterclaim for return commission.

        In June 1999, White Mountains sold VGI to Unitrin. As part of the VGI Sale, White Mountains has provided Unitrin with adverse loss development protection of up to $50.0 million on loss reserves sold to Unitrin. During 2004, White Mountains paid Unitrin $47 million for a full release of its obligation in this matter.


NOTE 19. Consolidating Financial Information

MANAGEMENT'S RESPONSIBILITY FOR FINANCIAL STATEMENTS

        Management is responsible for the preparation and fair presentation of the financial statements included in this report. The financial statements have been prepared in conformity with GAAP in the United States. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

        The Audit Committee of the Board, which is comprised entirely of independent, qualified directors, is responsible for the oversight of our accounting policies, financial reporting and internal control including the appointment and compensation of our independent registered public accounting firm. The Audit Committee meets periodically with management, our independent registered public accounting firm and our internal auditors to ensure they are carrying out their responsibilities. The Audit Committee is also responsible for performing an oversight role by reviewing our financial reports. Our independent registered public accounting firm and internal auditors have full and unlimited access to the Audit Committee, with or without management present, to discuss the adequacy of internal control over financial reporting and any other matters which they believe should be brought to their attention.


MANAGEMENT'S ANNUAL REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

        Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. There are inherent limitations in the effectiveness of any internal control over financial reporting, including the possibility of human error and the circumvention or overriding of internal control. Accordingly, even effective internal control over financial reporting can provide only reasonable assurance with respect to financial statement preparation. Further, an effective internal control environment as of a point in time may become inadequate in the future because of changes in conditions, or deterioration in the degree of compliance with the policies and procedures.

        We assessed the effectiveness of White Mountains' internal control over financial reporting as of December 31, 2004. Our assessment did not include an assessment of the internal control over financial reporting for certain recent acquisitions. These acquisitions were Sirius, the Sierra group, Tryg-Baltica and Atlantic Specialty which represent 17.0%, 2.4%, .9% and ..5% of White Mountains' total assets as of December 31, 2004, respectively, and 11.3%, .5%, .6%, and 6.1%, respectively, of White Mountains' total revenue for the year ended December 31, 2004. In making our assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework. Based on this assessment, we have concluded that White Mountains maintained effective internal control over financial reporting as of December 31, 2004.

        PricewaterhouseCoopers LLP, the Company's independent registered public accounting firm, has audited management's assessment of the effectiveness of White Mountains' internal control over financial reporting as of December 31, 2004 as stated in their report which appears on page F-72.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of White Mountains Insurance Group, Ltd.:

        We have completed an integrated audit of White Mountains Insurance Group, Ltd.'s 2004 consolidated financial statements and of its internal control over financial reporting as of December 31, 2004 and audits of its 2003 and 2002 consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Our opinions, based on our audits, are presented below.

Consolidated financial statements and financial statement schedules

        In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all material respects, the financial position of White Mountains Insurance Group, Ltd. and its subsidiaries at December 31, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2004 in conformity with accounting principles generally accepted in the United States of America. In addition, in our opinion, the financial statement schedules listed in the accompanying index present fairly, in all material respects, the information set forth therein when read in conjunction with the related consolidated financial statements. These financial statements and financial statement schedules are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements and financial statement schedules based on our audits. We conducted our audits of these statements in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit of financial statements includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Internal control over financial reporting

        Also, in our opinion, management's assessment, appearing under Item 9A and included in Management's Annual Report on Internal Control Over Financial Reporting appearing on page F-71, that the Company maintained effective internal control over financial reporting as of December 31, 2004 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), is fairly stated, in all material respects, based on those criteria. Furthermore, in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2004, based on criteria established in Internal Control—Integrated Framework issued by the COSO. The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express opinions on management's assessment and on the effectiveness of the Company's internal control over financial reporting based on our audit. We conducted our audit of internal control over financial reporting in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. An audit of internal control over financial reporting includes obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we consider necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

F-72



        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        As described in Management's Annual Report on Internal Control Over Financial Reporting, management has excluded Sirius, Sierra group, Tryg-Baltica and Atlantic Specialty from its assessment of internal control over financial reporting as of December 31, 2004 because they were acquired by the Company in purchase business combinations during 2004. As a result, we have also excluded Sirius, Sierra group, Tryg-Baltica and Atlantic Specialty from our audit of internal control over financial reporting. Sirius, Sierra group, Tryg-Baltica and Atlantic Specialty are wholly-owned subsidiaries whose total assets and total revenues represent 17.0%, 2.4%, .9%, .5%, and 11.3%, .5%, .6%, 6.1%, respectively, of the related consolidated financial statement amounts as of and for the year ended December 31, 2004.

                                                                   Exhibit 10.10

FOLKSAMERICA HOLDING COMPANY, INC.
LONG-TERM INCENTIVE PLAN - 2003 AND PRIOR

1.   PURPOSE

     The purpose of the Folksamerica Holding Company, Inc. Long-Term Incentive
     Plan (the "Plan") is to advance the interests of Folksamerica Holding
     Company, Inc. (the "Company") and its stockholders by providing long-term
     incentives to certain key executives of the Company and of its
     subsidiaries.

2.   ADMINISTRATION

     The Plan shall be administered by the Human Resources Committee ( the
     "Committee") of the Board of Directors (the "Board") of the Company. No
     member of the Committee shall be an employee of the Company or a subsidiary
     of the Company or shall have been eligible within one year prior to his
     appointment to receive awards under the Plan ("Awards") or to receive
     awards under any other plan of the Company or its subsidiaries under which
     participants are entitled to acquire stock, stock options or stock
     appreciation rights of the Company or any of its subsidiaries.

     The Committee shall have exclusive authority to select the employees to be
     granted Awards, to determine the type, size and terms of the Awards and to
     prescribe the form of the instruments embodying Awards. The Committee shall
     be authorized to interpret the Plan and the Awards granted under the Plan,
     to establish, amend and rescind any rules and regulations relating to the
     Plan and to make any other determinations which it believes necessary or
     advisable for the administration of the Plan. The Committee may correct any
     defect or supply any omission or reconcile any inconsistency in the Plan or
     in any Award in the manner and to the extent the Committee deems desirable
     to carry it into effect. Any decision of the Committee in the
     administration of the Plan, as described herein, shall be final and
     conclusive. The Committee may act only by a majority of its members in
     office, except that the members thereof may authorize any one or more of
     their number or any officer of the Company to execute and deliver documents
     on behalf of the Committee. No member of the Company shall be liable for
     anything done or omitted to be done by him or by any other member of the
     Committee in connection with the Plan, except for his own willful
     misconduct or as expressly provided by statute.

3.   PARTICIPATING SUBSIDIARIES

     If a subsidiary of the Company wishes to participate in the Plan and its
     participation shall have been approved by the Board, the Board of Directors
     of the subsidiary shall adopt a resolution in form and substance
     satisfactory to the Committee authorizing participation by the subsidiary
     in the Plan. As used herein, "subsidiary" shall mean a "subsidiary

                                       I-1


     corporation" as defined in Section 424(f) of the Internal Revenue Code of
     1986, as amended (the "Code").

     A subsidiary may cease to participate in the Plan at any time by action of
     the Board or by action of the Board of Directors of such subsidiary, which
     latter action shall be effective not earlier than the date of delivery to
     the Secretary of the Company of a certified copy of a resolution of the
     subsidiary's Board of Directors taking such action. Termination of
     participation in the Plan shall not relieve a subsidiary of any obligations
     theretofore incurred by it pursuant to the Plan.

4.   AWARDS

     (a)  TYPE OF AWARDS. Awards shall be limited to the following four types:
          (i) "Stock Options," (ii) "Stock Appreciation Rights", (iii)
          "Restricted Stock" and (iv) "Performance Shares." Stock Options, which
          include "Incentive Stock Options" and other stock options or
          combinations thereof, are rights to purchase shares of Common Stock of
          the Company having a par value of $.01 per share ("Shares"). A Stock
          Appreciation Right is a right to receive, without payment to the
          Company, cash and/or Shares in lieu of the purchase of Shares under
          the Stock Option to which the Stock Appreciation Right relates.

     (b)  MAXIMUM NUMBER OF SHARES THAT MAY BE ISSUED. A maximum of 1,000,000
          Shares, subject to adjustment as provided in paragraph 14, may be
          issued under the Plan. For purposes of the foregoing, the exercise of
          a Stock Appreciation Right shall constitute the issuance of Shares
          equal to the Shares covered by the related Stock Option. Shares issued
          pursuant to the Plan may be either authorized but unissued Shares or
          reacquired Shares, or both. If any Shares issued as Restricted Stock
          shall be repurchased pursuant to the Company's option described in
          paragraph 6 below, or if any Shares issued under the Plan shall be
          reacquired pursuant to restrictions imposed at the time of issuance,
          such Shares may again be issued under the Plan.

  (c)     RIGHTS WITH RESPECT TO SHARES.

          (i)    An employee to whom Restricted Stock has been issued shall have
                 prior to the expiration of the Restricted Period or the earlier
                 repurchase of such Shares as herein provided, ownership of such
                 Shares, including the right to vote the same and to receive
                 dividends thereon, subject, however, to the options,
                 restrictions and limitations imposed thereon pursuant hereto.

          (ii)   An employee to whom Stock Options, Stock Appreciation Rights or
                 Performance Shares are granted (and any person succeeding to
                 such employee's rights pursuant to the Plan) shall have no
                 rights as a shareholder with respect to any Shares issuable
                 pursuant thereto until the date of the issuance of a stock
                 certificate (whether or not delivered) therefor. Except as
                 provided in paragraph 14, no adjustment shall be made

                                       I-2


                 for dividends, distributions or other rights (whether ordinary
                 or extraordinary, and whether in cash, securities or other
                 property) the record date for which is prior to the date such
                 stock certificate is issued.

          (iii)  The Company, in its discretion, may hold custody during the
                 Restricted Period of any Shares of Restricted Stock.

     (d)  MARKET VALUE OF SHARES. "Market value of Share(s)" on any day means
          (i) if Shares are listed on the New York Stock Exchange, the last sale
          price, regular way, or, in case no such sale takes place on such day,
          the average of the closing bid and asked prices, regular way, in
          either case as reported in the principal consolidated transaction
          reporting system with respect to securities listed or admitted to
          trading on the New York Stock Exchange or, if Shares are not listed or
          admitted to trading on the New York Stock Exchange, as reported in the
          principal consolidated transaction reporting system with respect to
          securities listed on the principal national securities exchange on
          which Shares are listed or admitted to trading or, if Shares are not
          listed or admitted to trading on any national securities exchange, the
          last quoted sale price or, if not so quoted, the average of the high
          bid and the low asked prices in the over-the-counter market, as
          reported by NASDAQ or such other system then in use, or, if on any
          such date Shares are not quoted by any such organization, the average
          of the closing bid and asked prices as furnished by one or more
          professional market makers making a market in Shares and (ii) if
          Shares are not publicly held or so listed or publicly traded, the
          fully diluted book value per Share as determined by the Committee in
          accordance with United States generally accepted accounting
          principles.

5.   STOCK OPTIONS AND STOCK APPRECIATION RIGHTS

     The Committee may grant Stock Options (including, in its discretion, Stock
     Appreciation Rights) either alone or, as provided in paragraph 7, in
     conjunction with Performance Shares. A maximum of 10,000 Stock Options and
     Stock Appreciation Rights (not including Stock Appreciation Rights attached
     to Stock Options) may be issued in one year to an employee. Each Stock
     Option shall comply with the following terms and conditions:

     (a)  The exercise price shall not be less than the greater of (i) the
          fair market value of the Shares subject to such Stock Option at the
          time of grant, as determined in good faith by the Committee, or (ii)
          the par value of such Shares. However, the exercise price of an
          Incentive Stock Option granted to an employee who owns stock
          representing more than ten percent (10%) of the voting power of all
          classes of stock of the Company or of a subsidiary (a "Ten Percent
          Employee") shall not be less than the greater of 110 % of such fair
          market value, or the par value of such Shares.

     (b)  The Committee shall initially determine the number of Shares to be
          subject to each Stock Option. The number of Shares subject to a Stock
          Option will

                                       I-3


          subsequently be reduced (i) on a share-for-share basis to the extent
          that Shares under such Stock Option are used to calculate the cash
          and/or Shares received pursuant to exercise of a Stock Appreciation
          Right attached to such Stock Option, and (ii) on a one-for-one basis
          to the extent that any Performance Shares granted in conjunction with
          such Stock Option pursuant to subparagraph 7(a) are paid, such
          reduction to be made in accordance with the provisions of subparagraph
          7(e)(ii).

     (c)  The Stock Option shall not be transferable by the optionee otherwise
          than by will or the laws of descent and distribution, and shall be
          exercisable during his lifetime only by him.

     (d)  The Stock Option shall not be exercisable:

          (i)    in case of any Incentive Stock Option as defined in Section 422
                 (b) of the Code, after the expiration of ten years from the
                 date it is granted, and in the case of any other Stock Option,
                 after the expiration of ten years from the date it is granted.
                 Any Stock Option may be exercised during such period only at
                 such time or times as the Committee may establish;

          (ii)   unless payment in full is made for the Shares being acquired
                 thereunder at the time of exercise (including any federal,
                 state or local income or other taxes which the Committee
                 determines are required to be withheld in respect of such
                 shares); such payment shall be made (A) in United States
                 dollars by cash or check, or (B) by tendering to the Company
                 Shares owned by the person exercising the Stock Option and
                 having a fair market value equal to the cash exercise price
                 thereof, such fair market value to be determined in such
                 reasonable manner as may be provided for from time to time by
                 the Committee or as may be required in order to comply with or
                 to conform to the requirements of any applicable or relevant
                 laws or regulations, or (C) by a combination of United States
                 dollars and Shares as aforesaid;

          (iii)  unless the person exercising the Stock Option has been, at all
                 times during the period beginning with the date of grant of the
                 Stock Option and ending on the date three months prior to such
                 exercise, an officer or employee of the Company or a
                 subsidiary, or of a corporation, or a parent or subsidiary of a
                 corporation, issuing or assuming the Stock Option in a
                 transaction to which Section 424 (a) of the Code is applicable,
                 except that:

                 (A)  if such person shall cease to be an officer or employee of
                      the Company or one of its subsidiary corporations solely
                      by reason of a period of Related Employment as defined in
                      paragraph 9, he may, during such period of Related
                      Employment (but in no event after the Stock Option has
                      expired under the provisions of

                                       I-4


                      subparagraph 5(d)(i) hereof), exercise such Stock Option
                      as if he continued to be such an officer or employee; or

                 (B)  if an optionee shall become disabled as defined in
                      paragraph 8 he may, at any time within three years of the
                      date he becomes disabled (but in no event after the Stock
                      Option has expired under the provisions of subparagraph
                      5(d)(i) hereof), exercise the Stock Option with respect to
                      (i) any Shares as to which he could have exercised the
                      Stock Option on the date he became disabled and (ii) if
                      the Stock Option is not fully exercisable on the date he
                      becomes disabled, the number of additional Shares as to
                      which the Stock Option would have become exercisable had
                      he remained an employee through the next two dates on
                      which additional Shares were scheduled to become
                      exercisable under the Stock Option; or

                 (C)  if an optionee shall die while holding a Stock Option, his
                      executors, administrators, heirs or distributees, as the
                      case may be, at any time within one year after the date of
                      such death (but in no event after the Stock Option has
                      expired under the provisions of subparagraph 5(d)(i)
                      hereof), may exercise the Stock Option with respect to (i)
                      any Shares as to which the decedent could have exercised
                      the Stock Option at the time of his death, and (ii) if the
                      Stock Option is not fully exercisable on the date of his
                      death, the number of additional Shares as to which the
                      Stock Option would have become exercisable had he remained
                      an employee through the next two dates on which additional
                      Shares were scheduled to become exercisable under the
                      Stock Option provided, however, that if death occurs
                      during the three-year period following a disability as
                      described in subparagraph 5(d)(iv)(B) hereof, the
                      three-year period following a retirement as described in
                      subparagraph 5(d)(iv)(D) hereof or any period following a
                      voluntary termination in respect of which death, the
                      number of additional Shares as to which the Stock Option
                      would have become exercisable had he remained an employee
                      through the next date or, if applicable, two dates on
                      which additional Shares were scheduled to become
                      exercisable under the Stock Option provided, however, that
                      if death occurs during the three-year period following a
                      disability as described in subparagraph 5(d)(iv)(B)
                      hereof, the three-year period following a retirement as
                      described in subparagraph 5(d)(iv)(D) hereof or any period
                      following a voluntary termination in respect of which the
                      Board has exercised its discretion to grant continuing
                      exercise rights as provided in subparagraph 5(d)(iv)(E)
                      hereof, the Stock Option shall not become exercisable as
                      to any Shares in addition to those as to

                                       I-5


                      which the decedent could have exercised the Stock Option
                      at the time of his death; or

                 (D)  if such person shall retire under an approved retirement
                      program of the Company or a subsidiary (or such other plan
                      as may be approved by the Committee, in its sole
                      discretion, for this purpose) while holding a Stock Option
                      which has not expired and has not been fully exercised,
                      such person, at any time within three years after his
                      retirement (but in no event after the Stock Option has
                      expired under the provisions of subparagraph 5(d)(i)
                      hereof), may exercise the Stock Option with respect to any
                      Shares as to which he could have exercised the Stock
                      Option on the date he retired; or

                 (E)  it such person shall voluntarily terminate his employment
                      with the Company, the Board may determine that the
                      optionee may exercise the Stock Option with respect to
                      some or all of the Shares subject to the Stock Option as
                      to which it would not otherwise be exercisable on the date
                      of his voluntary termination provided, however, that in no
                      event may such exercise take place after the Stock Option
                      has expired under the provisions of subparagraph 5(d)(i)
                      hereof.

     (e)  The aggregate fair market value of Shares (determined at the time of
          grant of the Stock Option pursuant to subparagraph 5(a) of the Plan)
          with respect to which Incentive Stock Options granted to any employee
          under the Plan are exercisable, for the first time, by such employee
          during any calendar year may not exceed $100,000.

     (f)  If the Committee, in its discretion, so determines, there may be
          related to the Stock Option, either at the time of grant or by
          amendment, a Stock Appreciation Right which shall be subject to such
          terms and conditions, not inconsistent with the Plan, as the Committee
          shall impose, including the following:

          (i)    A Stock Appreciation Right may be exercised only:

                 (A)  to the extent that the Stock Option to which it relates is
                      at the time exercisable, and

                 (B)  if:

                      (1)  in the case of a Stock Option other than an Incentive
                           Stock Option only, such Stock Option will expire by
                           its terms within 30 days (90 days if the optionee is
                           at the time an officer of the Company who is required
                           to file reports pursuant to Section 16(a) of the
                           Securities and Exchange Act of 1934, as amended (the
                           "Exchange Act"));

                                       I-6


                      (2)  the optionee has become disabled or ceased to be an
                           officer or employee by reason of his retirement under
                           an approved retirement program of the Company or a
                           subsidiary (or such other plan as may be approved by
                           the Committee, in its sole discretion, for this
                           purpose); or

                      (3)  the optionee has died.

                           However, if the Stock Option to which the Stock
                           Appreciation Right relates is exercisable and if the
                           optionee is at the time an officer of the Company who
                           is required to file reports pursuant to Section 16(a)
                           of the Exchange Act, the Stock Appreciation Right
                           may, subject to the approval of the Committee, be
                           exercised during such periods, as may be specified by
                           the Committee;

          (ii)   A Stock Appreciation Right shall entitle the optionee (or any
                 person entitled to act under the provisions of subparagraph
                 5(d)(iv)(C) hereof) to surrender unexercised the related Stock
                 Option (or any portion of such Option) to the Company and to
                 receive from the Company in exchange therefor that number of
                 Shares having an aggregate value equal to the excess of the
                 value of one Share over the Stock Option price per share, times
                 the number of Shares subject to the Stock Option, or portion
                 thereof, which is so surrendered. The Committee shall be
                 entitled to elect to settle the obligation arising out of the
                 exercise of a Stock Appreciation Right by the payment or cash
                 equal to the aggregate value of the Shares it would otherwise
                 be obligated to deliver or partly by the payment of cash and
                 partly by the delivery of Shares. Any such election shall be
                 made within 15 business days after the receipt by the Committee
                 of written notice of the exercise of the Stock Appreciation
                 Right. The value of a Share for this purpose shall be the fair
                 market value thereof on the last business day preceding the
                 date of the election to exercise the Stock Appreciation Right,
                 provided that if notice of such election is received by the
                 Committee more than three business days after the date of such
                 election (as such date of election is stated in the notice of
                 election), the Committee may, but need not, determine the value
                 of a Share as of the day preceding the date on which the notice
                 of election is received;

          (iii)  No fractional Shares shall be delivered under this subparagraph
                 5(f), but in lieu thereof a cash adjustment shall be made; and

          (iv)   in the case of a Stock Appreciation Right attached to an
                 Incentive Stock Option, such Stock Appreciation Right shall
                 only be transferable when such Incentive Stock Option is
                 transferable pursuant to Section 5 (c) hereof.

                                       I-7


     (g)  Notwithstanding anything herein to the contrary:

          (i)    in the event an Unfriendly Change in Control of the Company, as
                 defined in subparagraph 10(b), occurs, then as of the
                 Acceleration Date, as defined in subparagraph 10(b), each Stock
                 Option granted hereunder shall be exercisable in full;
                 provided, however, that in the case of an officer subject to
                 Section 16(b) of the Exchange Act, no Stock Option shall become
                 exercisable until the expiration of the period ending six
                 months after the date of grant of the Stock Option hereunder;
                 and

          (ii)   in the event a Change in Control as defined in subparagraph
                 10(a) occurs and within 24 months thereafter: (A) there is a
                 Termination Without Cause, as defined in paragraph 11, of an
                 optionee's employment; or (B) there is a Constructive
                 Termination as defined in paragraph 12, of an optionee's
                 employment; or (C) there occurs an Adverse Change in the Plan,
                 as defined in paragraph 13, in respect of an optionee affecting
                 any Award held by such optionee and if the optionee then holds
                 a Stock Option,

                      (1)  In the case of a Termination Without Cause or a
                           Constructive Termination, the optionee may exercise
                           the entire Stock Option, at any time within 30 days
                           of such Termination Without Cause or such
                           Constructive Termination (but in no event after the
                           option has expired under the provisions of
                           subparagraphs (5)(d)(i)), and

                      (2)  in the case of an Adverse Change in the Plan, the
                           optionee may exercise the entire Stock Option at any
                           time after such Adverse Change in the Plan in respect
                           of him and prior to the date 30 days following his
                           termination of employment as a result of a
                           Termination Without Cause or a Constructive
                           Termination (but in no event after the option has
                           expired under the provisions of subparagraph
                           5(d)(i)). Notwithstanding anything in this
                           subparagraph 5(g) to the contrary, (x) in the case of
                           an officer subject to Section 16(b) of the Exchange
                           Act, no Stock Option shall become exercisable until
                           the expiration of the period ending six months after
                           the date of grant of the Stock Option hereunder.

6.   RESTRICTED STOCK

     Each Award of Restricted Stock shall comply with the following terms and
     conditions:

     (a)  The Committee shall determine the number of Shares to be issued to a
          participant pursuant to the Award.

                                       I-8


     (b)  Shares issued may not be sold, assigned, transferred, pledged,
          hypothecated or otherwise disposed of, except by will or the laws of
          descent and distribution, for such period from the date on which the
          Award is granted (the "Restricted Period") as the Committee shall
          determine. The Company shall have the option to repurchase the Shares
          subject to the Award at such price as the Committee shall have fixed,
          in its sole discretion, when the Award was made, which option will be
          exercisable if the participant's continuous employment with the
          Company or a subsidiary shall terminate for any reason, except solely
          by reason of an event described in paragraph 6(c), prior to the
          expiration of the Restricted Period or the earlier lapse of the
          option. Such option shall be exercisable on such terms, in such manner
          and during such period as shall be determined by the Committee when
          the Award is made. Certificates for Shares issued pursuant to
          Restricted Stock Awards shall bear an appropriate legend referring to
          the foregoing option and other restrictions. Any attempt to dispose of
          any such Shares in contravention of the foregoing option and other
          restrictions shall be null and void and without effect. If Shares
          issued pursuant to a Restricted Stock Award shall be repurchased
          pursuant to the option described above, the participant to whom the
          Award was granted, or in the event of his death after such option
          become exercisable, his executor or administrator, shall forthwith
          deliver to the Secretary of the Company any certificates for the
          Shares awarded to the participant, accompanied by such instruments of
          transfer, if any, as may reasonably be required by the Secretary of
          the Company. If the option described above is not exercised by the
          Company, such option and the restriction imposed pursuant to the first
          sentence of this subparagraph 6(b) shall terminate and be of no
          further force and effect. Notwithstanding anything to the contrary in
          this paragraph 6 (b), neither any Restricted Period nor any option
          shall lapse to the extent the Company or any subsidiary would be
          unable to take a deduction with respect to such lapse by reason of
          Section 162 (m) of the Code.

     (c)  If a participant who has been in the continuous employment of the
          Company or of a subsidiary shall,

          (i)    die or become disabled (as defined in paragraph 8) during the
                 Restricted Period, the option of the Company to repurchase (and
                 any and all other restrictions on) all Shares awarded to him
                 under such Award shall lapse and cease to be effective as of
                 the date on which his death or disability occurs, or

          (ii)   voluntarily terminate his employment with the Company or retire
                 under an approved retirement plan of the Company or of a
                 subsidiary (or such other retirement plan as may be approved by
                 the Committee, in its sole discretion, for this purpose) during
                 the Restricted Period, the Board may determine that the option
                 to repurchase and any and all other restrictions on some or all
                 of the Shares awarded to him under such Award, if such option
                 and other restrictions are still in effect, shall lapse and
                 cease to be

                                       I-9


                 effective as the date on which such voluntary termination or
                 retirement occurs.

     (d)  In the event within 24 months after a Change in Control as defined in
          subparagraph 10(a) and during the Restricted Period:

          (i)    there is a Termination Without Cause, as defined in paragraph
                 11, of the employment of a participant;

          (ii)   there is a Constructive Termination, as defined in paragraph
                 12, of the employment of a participant; or

          (iii)  there occurs an Adverse Change in the Plan, as defined in
                 paragraph 13, in respect of a participant, the option to
                 repurchase (and any and all other restrictions on) all Shares
                 awarded to him under his Award shall lapse and cease to be
                 effective as of the date on which such event occurs.

7.   PERFORMANCE SHARES

     The Award of Performance Shares to a participant will entitle him to
     receive, without payment to the Company, all or part of a specified amount
     (the "Actual Value") determined by the Committee, if the terms and
     conditions specified herein and in the Award are satisfied. Payment in
     respect of an Award shall be made as provided in subparagraph 7(e). Each
     Award of Performance Shares shall be subject to the following terms and
     conditions:

     (a)  The Committee shall determine the number of Performance Shares to be
          granted to each participant and whether or not such Performance Shares
          are granted in conjunction with a Stock Option (the "Associated Stock
          Option"). The "Maximum Value" of each Performance Share shall be the
          market value per Share on the date the award is paid or becomes
          payable to participants. Performance Shares may be issued in different
          classes or series having different terms and conditions. In the case
          of any Performance Shares granted in conjunction with an Associated
          Stock Option, the number of Performance Shares shall initially be
          equal to the number of Shares which are subject to the Associated
          Stock Option, but the number of such performance Shares shall be
          reduced on a one for one basis to the extent that (A) Shares are
          purchased upon exercise of the Associated Stock Option, or (B) Shares
          may no longer be purchased under the Associated Stock Option because
          the Associated Stock Option or a part thereof has been surrendered
          unexercised pursuant to exercise of a Stock Appreciation Right
          attached to such Associated Stock Option.

     (b)  The award period ("Award Period") in respect of any Award of
          Performance Shares shall be such period as the Committee shall
          determine commencing as of the beginning of the fiscal year of the
          Company in which such Award is made. An Award Period may contain a
          number of performance periods; each performance

                                      I-10


          period shall commence on or after the first day of the Award Period
          and shall end no later than the last day of the Award Period. At the
          time each Award is made, the Committee shall establish performance
          objectives to be attained within the performance periods as the means
          of determining the Actual Value. The performance objectives shall be
          based on the Company's growth in intrinsic business value, as outlined
          below, for each of the fiscal years comprising the performance
          period(s). The Actual Value of a Performance Share shall be equal to
          its Maximum Value only if the performance objectives are attained in
          full, but the Committee shall specify the manner in which the Actual
          Value of a Performance Share shall be a portion of such Maximum Value
          if the performance objectives are met in part. In determining Actual
          Value, the Committee may either (i) multiply the total number of
          Shares available for payout at that time with respect to the
          participant by the Actual Value of each individual Share or (ii)
          multiply the Maximum Value of each individual Share by a number of
          Shares equal to or less than the total number of Shares available for
          payout, provided that products obtained in (i) and (ii) are the same.
          The Company's growth in intrinsic business value for any performance
          period shall be measured individually or as a combination of the
          following measurement factors: (i) the sum of the Company's return on
          equity (computed in accordance with generally accepted accounting
          principles ("GAAP")) for any fiscal years in the performance period
          divided by the number of fiscal years in the performance period, (ii)
          the growth in market value per Share for any fiscal years in the
          performance period divided by the number of fiscal years in the
          performance period, or (iii) the sum of the Company's economic return
          on equity (computed as the Company's GAAP return on equity adjusted
          for changes in the intrinsic value of assets whose value differs from
          their GAAP carrying value) for any fiscal years in the performance
          period divided by the number of fiscal years in the performance
          period. The Committee shall determine, no later than the award date
          and prior to the commencement of the performance period of such award,
          which of the above measurement factor(s) will be the relevant
          performance objectives for each award.

     (c)  Performance Shares shall be canceled if the participant's continuous
          employment with the Company or any of its subsidiaries shall terminate
          for any reason prior to the end of the Award Period (in which event
          the Associated Stock Option, if any, shall continue in effect in
          accordance with its terms), except solely by reason of a period of
          Related Employment as defined in paragraph 9, and except as otherwise
          specified in this subparagraph 7(c) or in subparagraph 7(d).
          Notwithstanding the foregoing and without regard to subparagraph 7(b),
          if a participant shall:

          (i)    while in such employment, die or become disabled as described
                 in paragraph 8 prior to the end of the Award Period, the
                 Performance Shares shall be canceled at the end of the next
                 ending performance period and he, or his legal representative,
                 as the case may be, shall receive payment in respect of such
                 Shares which he would have received had he been in continuous
                 employment with the Company through the end of that period

                                      I-11


                 and had the individual performance objectives, if any, that
                 were imposed been achieved; provided, however, that no such
                 continuation shall be deemed to have occurred for purposes of
                 applying subparagraph 7(d) in the event of an Adverse Change in
                 the Plan in respect of the participant following a Change in
                 Control; or

          (ii)   retire under an approved retirement program of the Company or a
                 subsidiary (or such other plan as may be approved by the
                 Committee, in its sole discretion, for this purpose) prior to
                 the end of the Award Period, and

                 (A)  at the time of his retirement, the participant is 65 years
                      old or older, the Performance Shares shall be canceled at
                      the end of the next ending performance period, and he
                      shall receive the Maximum Value in respect to such Shares,
                      at the date of cancellation,

                 (B)  at the time of his retirement the participant is less than
                      65 years old and his retirement occurs prior to the end of
                      the first performance period, and before 24 months have
                      elapsed since the first day of the Award Period, the
                      participant shall receive payment with respect to the
                      Actual Value of one-ninth of the Performance Shares
                      awarded to him under the Award, and

                 (C)  at the time of his retirement the participant is less than
                      65 years old and his retirement occurs prior to the end of
                      the first performance period and after at least 24 months
                      have elapsed since the first day of the Award Period, the
                      participant shall receive payment with respect to the
                      Actual Value of two-ninths of the Performance Shares
                      awarded to him under the Award.

     (d)  If within 24 months after a Change in Control of the Company as
          defined in subparagraph 10(a) and prior to the end of an Award Period:

          (i)    there is a Termination Without Cause, as defined in paragraph
                 11, of the employment of a participant;

          (ii)   there is a Constructive Termination, as defined in paragraph
                 12, of the employment of a participant; or

          (iii)  there occurs an Adverse Change in the Plan, as defined in
                 paragraph 13, in respect of a participant, then:

                 (A)  the participant shall receive the Maximum Value of:

                                      I-12


                      (1)  that number of Performance Shares which is in the
                           same proportion to the total number of Performance
                           Shares awarded to the participant under such Award as

                           (x)  the number of full months which have elapsed
                                since the first day of the Award Period to the
                                end of the first month in which occurs one of
                                the events described in clauses (i), (ii) or
                                (iii) of subparagraph 7(d) is to

                           (y)  the total number of months in the Award Period,
                                less

                      (2)  the number of Performance Shares awarded to the
                           participant under the Award in respect of which
                           payment has already been made to the participant, and

                 (B)  if the number of Performance Shares determined pursuant to
                      subclause (1) of clause (A) is less than the number of
                      Performance Shares subject to the particular Award, the
                      participant shall receive the Actual Value of the
                      remaining Performance Shares. The Actual Value of the
                      remaining Performance Shares shall be determined as
                      follows:

                      (x)  if the Board shall have determined, prior to the
                           Change in Control and based on the most recent
                           performance status reports, that the performance
                           objectives for the particular Award were being met at
                           the date of the determination, the Actual Value of
                           the remaining Performance Shares subject to the
                           particular Award shall be equal to their Maximum
                           Value, and

                      (y)  it the determination of the Board was that the
                           performance objectives for the particular Award were
                           not being met at the date of the determination, the
                           Actual Value of the remaining Performance Shares
                           subject to the particular Award shall be such amount
                           as shall have been determined by the Board as
                           provided above in this subparagraph 7(d), but in no
                           event shall Actual Value be less than fifty percent
                           (50%) of Maximum Value. Payment of any amount in
                           respect of Performance Shares as described above in
                           this subparagraph 7(d) shall be made as promptly as
                           possible after the occurrence of one of the events
                           described in clauses 7(d)(i) through 7(d)(iii).
                           Notwithstanding anything herein to the contrary, if,
                           following a Change in Control of the Company as
                           defined in subparagraph 10(a), a

                                      I-13


                           participant's employment remains continuous through
                           the end of a performance period, then the participant
                           shall be paid with respect to those Performance
                           Shares for which he would have been paid had there
                           not been a Change in Control and the Actual Value of
                           those Shares shall be determined in accordance with
                           subparagraph 7(e).

     (e)  Except as otherwise provided in subparagraph 7(d), as soon as
          practicable after the end of the performance period or such earlier
          date as the Committee in its sole discretion may designate, the
          Committee shall determine whether the conditions of subparagraphs 7(b)
          and/or 7(c) hereof have been met and, if so, shall certify such fact
          to the Board of Directors and shall ascertain the Actual Value of the
          Performance Shares. If the Performance Shares:

          (i)    were not awarded in conjunction with an Associated Stock
                 Option, the Committee shall cause an amount equal to the Actual
                 Value of the Performance Shares earned by the participant to be
                 paid to him or his beneficiary; or

          (ii)   were awarded in conjunction with an Associated Stock Option,
                 the Committee shall determine, in accordance with criteria
                 specified by the Committee when the Award was made, (A) to
                 cancel the Performance Shares, in which event no amount in
                 respect thereof shall be paid to the participant or his
                 beneficiary, and the Associated Stock Option shall continue in
                 effect in accordance with its terms, (B) to pay the Actual
                 Value of the Performance Shares to the participant or his
                 beneficiary, in which event the Associated Stock Option shall
                 be canceled, or (C) to pay to the participant or his
                 beneficiary the Actual Value of only a portion of the
                 Performance Shares, in which event (1) all such Performance
                 Shares shall be canceled and (2) the Associated Stock Option
                 shall be canceled only as to a number of Shares equal to the
                 number of Performance Shares so paid. Such determination by the
                 Committee shall, if practicable, be made during the three-month
                 period following the end of the performance period, or during
                 such earlier period as shall be designated by the Committee and
                 shall be made pursuant to criteria, specified by the Committee,
                 which shall be uniform for all Awards having the same
                 performance period.

                 Payment of any amount in respect of the Performance Shares
                 shall be made by the Company as promptly as practicable or
                 shall be deferred to such other time or times as the Committee
                 shall determine, and may be made in cash, in Shares, or partly
                 in cash and partly in Shares as determined by the Committee.
                 Such deferred payments may be made by undertaking to pay cash
                 in the future, together with such additional

                                      I-14


                 amounts as may accrue thereon until the date or dates of
                 payment, as determined by the Committee in its discretion.

8.   DISABILITY

     For the purposes of this Plan, a participant shall be deemed to be disabled
     if the Committee shall determine that (i) the physical or mental condition
     of the participant is such as would entitle him to payment of monthly
     disability benefits under any disability plan of the Company or a
     subsidiary in which he is a participant or (ii) he is not a participant in
     any such plan but his physical or mental condition would entitle him to
     benefits under any disability plan of the Company if he were a participant
     therein.

9.   RELATED EMPLOYMENT

     For the purposes of this Plan, Related Employment shall mean the employment
     of an individual by an employer which is neither the Company nor a

     and continued at the request of the Company or a subsidiary; (ii)
     immediately prior to undertaking such employment, the individual was an
     officer or employee of the Company or a subsidiary, or was engaged in
     Related Employment as herein defined; and (iii) such employment is
     recognized by the Committee, in its sole discretion, as Related Employment
     for the purposes of this paragraph 9. The death or disability of an
     individual during a period of Related Employment as herein defined shall be
     treated, for purposes of this Plan, as if the death or onset of disability
     had occurred while the individual was an officer or employee of the
     Company.

10.  CHANGE IN CONTROL

     (a)  For purposes of this Plan, a "Change in Control of the Company" within
          the meaning of this subparagraph 10(a) shall occur if:

                 the Company; or

          (iii)  the business of the Company for which the participant's
                 services are principally performed is disposed of by the
                 Company pursuant to a sale or other disposition of all or
                 substantially all of the business or business

                 related assets of the Company (including stock of a subsidiary
                 of the Company). A Change in Control of the Company within the
                 meaning of this subparagraph 10(a) also may constitute an
                 Unfriendly Change in Control of the Company within the meaning
                 of this subparagraph 10(b).

     (b)  A Change in Control of the Company shall be deemed an "Unfriendly
          Change in Control of the Company" if:

          (i)    any person or group (within the meaning of Section 13(d) and
                 14(d)(2) of the Exchange Act), other than Fund American
                 Enterprises Holdings, Inc. (through its affiliate White
                 Mountains Holdings, Inc.), Folksam Mutual General Insurance
                 Company, Wiener Staedtische Allgemeine Versicherung, P & V
                 Assurances S.C., Forsikringsaktieselskapet Samvirke or the
                 Company, becomes the beneficial owner (within the meaning of
                 Rule 13d-3 under the Exchange Act) of more than fifty percent
                 (50%) of the Company's then outstanding Shares through a
                 transaction that is opposed by the Company's Chairman and Chief
                 Executive Officer, and

          (ii)   a majority of the Company's Continuing Directors, as defined in
                 subparagraph 10(c), by resolution adopted within 30 days
                 following the date the Company becomes aware that subparagraph
                 10(b)(i) has been satisfied, determines that a Change in
                 Control has occurred.

     For purposes of subparagraph 5(g), "Acceleration Date" shall mean the date
     on which a majority of the Company's Continuing Directors adopts a

          member of the Board (A) who is not an employee of the Company or its
          subsidiaries or of a holder of, or an employee or an affiliate of an
          entity or group that holds, more than fifty percent (50 %) of the
          Company's Shares and (B) who either was a member of the Board on
          January 1, 1997, or who subsequently became a director of the Company
          and whose election, or nomination for election, by the Company's
          shareholders was approved by a vote of a majority of the Continuing
          Directors then on the Board (which term, for purposes of this
          definition, shall mean the whole Board and not any committee thereof).
          Any action, approval of which shall require the approval of a majority
          of the Continuing Directors, may be authorized by one Continuing
          Director, if he is the only Continuing Director on the Board, but no
          such action may be taken if there are not Continuing Directors on the
          Board.

     "Cause" shall mean (a) an act or omission by the participant that
     constitutes a felony or any crime involving moral turpitude or (b) willful
     gross negligence or willful gross misconduct by the participant in
     connection with his employment by the Company or by a subsidiary which
     causes, or is likely to cause, material loss or damage to the Company.

12.  CONSTRUCTIVE TERMINATION

     "Constructive Termination" shall mean a termination of employment with the
     Company or a subsidiary at the initiative of the participant that the
     participant declares by prior written notice delivered to the Secretary of
     the Company to be a Constructive Termination by the Company or a subsidiary
     and which follows (a) a material decrease in his salary or (b) a material
     diminution in the authority, duties or responsibilities of his position
     with the result that the participant makes a determination in good faith
     that he cannot continue to carry out his job in substantially the same
     manner as it was intended to be carried out immediately before such
     diminution. Notwithstanding anything herein to the contrary, Constructive
     Termination shall not occur within the meaning of this paragraph 12 until
     and unless 30 days have elapsed from the date the Company receives such
     written notice without the Company curing or causing to be cured the
     circumstance or circumstances described in this paragraph 12 on the basis
     of which the declaration of Constructive Termination is given,

13.  ADVERSE CHANGE IN THE PLAN

     An "Adverse Change in the Plan" shall mean:

     (a)  termination of the Plan pursuant to subparagraph 19(a);

     (b)  amendment of the Plan pursuant to paragraph 18 that materially
          diminishes the value of Awards that maybe granted under the Plan,
          either to individual participants or in the aggregate, unless there is
          substituted concurrently authority to grant long-term incentive awards
          of comparable value to individual participants in the Plan or in the
          aggregate, as the case may be; or

     (c)  in respect of any holder of an Award a material diminution in his
          rights held under such Award (except as may occur under the terms of
          the Award as originally granted) unless there is substituted
          concurrently a long-term incentive award with a value at least
          comparable to the loss in value attributable to such diminution in
          rights.

14.  DILUTION AND OTHER ADJUSTMENTS

     In the event of any change in the Outstanding Shares of the Company by
     reason of any stock split, stock dividend, recapitalization, merger,
     consolidation, reorganization, combination or exchange of Shares or other
     similar event, and if the Committee shall determine, in its sole
     discretion, that such change equitably requires an adjustment in the number
     or kind of Shares that may be issued under the Plan pursuant to
     subparagraph

                                      I-17


     4(b), in the number or kind of Shares subject to, or the Stock Option price
     per share under, any outstanding Stock Option, in the number or kind of

     option price per share relating thereto, in the Maximum Value or Actual
     Value of Performance Shares which have been awarded to any participant, or
     in any measure of performance, then such adjustment shall be made by the
     Committee and shall be conclusive and binding for all purposes of the Plan.

15.  DESIGNATION OF BENEFICIARY BY PARTICIPANT

     A participant may name a beneficiary to receive any payment to which he
     maybe entitled in respect of Performance Shares under the Plan in the event
     of his death, on a form to be provided by the Committee. A participant may
     change his beneficiary from time to time in the same manner. If no
     designated beneficiary is living on the date on which any amount becomes
     payable to a participant's executors or administrators, the term
     "beneficiary" as used in the Plan shall include such person or persons.

16.  FINANCIAL ASSISTANCE

     If those members of the Board who are ineligible to receive Awards under
     the Plan determine that such action is advisable, the Company may assist
     any person to whom an Award has been granted in obtaining financing from
     the Company under a program of the Company or a subsidiary approved
     pursuant to applicable law or regulation, or from a bank or other third
     party, in such amount as is required to permit the payment of taxes in
     respect of such Award (or, in the case of an Award of a Stock Option, to
     permit the exercise thereof and/or the payment of any taxes in respect
     thereof) to the extent that such taxes (and Stock Option price) exceed the
     cash portion, it any, of the Award. Such assistance may take any form that
     the Committee deems appropriate, including but not limited to a direct loan
     from the Company or a subsidiary, a guarantee of the obligation by the
     Company or a subsidiary, or the maintenance by the Company or a subsidiary
     of deposits with such bank or third party.

17.  MISCELLANEOUS PROVISIONS

     (a)  No employee or other person shall have any claim or right to be
          granted an Award under the Plan. Neither the Plan nor any action taken
          hereunder shall be construed as giving an employee any right to be
          retained in the employ of the Company or any subsidiary.

     (b)  A participant's rights and interest under the Plan may not be assigned
          or transferred in whole or in part either directly or by operation of
          law or otherwise (except in the event of a participant's death),
          including but not limited to, execution, levy, garnishment,
          attachment, pledge, bankruptcy or in any other manner and no such
          right or interest of any participant in the Plan shall be subject to
          any obligation or liability of such participant.

                                      I-18


     (c)  No Shares shall be issued hereunder unless counsel for the Company
          shall be satisfied that such issuance will be in compliance with
          applicable Federal and state securities laws.

     (d)  The Company and its subsidiaries shall have the right to deduct from
          any payment made under the Plan any federal, state or local income or
          other taxes required by law to be withheld with respect to such
          payment. It shall be a condition to the obligation of the Company to
          issue Shares upon exercise of a Stock Option, upon settlement of a
          Stock Appreciation Right, or upon payment of a Performance Share that
          the participant (or any beneficiary or person entitled to payment
          under subparagraph 5(d)(iii)(C) hereof) pay to the Company, upon its
          demand, such amount as may be required by the Company for the purpose
          of satisfying any liability to withhold federal, state or local income
          or other taxes. If the amount requested is not paid, the Company may
          refuse to issue Shares.

     (e)  The expenses of the Plan shall be borne by the Company. However, if an
          Award is made to an employee of a subsidiary:

          (i)    if such Award results in payment of cash to the participant,
                 such subsidiary shall pay to the Company an amount equal to
                 such cash payment; and

          (ii)   if the Award results in the issuance to the participant of
                 Shares, such subsidiary shall pay to the Company an amount
                 equal to fair market value thereof, as determined by the
                 Committee, on the date such Shares are issued (or, in the case
                 of issuance of Restricted Stock or of Shares subject to
                 transfer and forfeiture conditions, equal to the fair market
                 value thereof on the date on which such Shares are no longer
                 subject to applicable restriction), minus the amount, if any
                 received by the Company in exchange for such Shares.

     (f)  The Plan shall be unfunded. The Company shall not be required to
          establish any special or separate fund or to make any other
          segregation of assets to assure the payment of any Award under the
          Plan.

     (g)  By accepting any Award or other benefit under the Plan, each
          participant and each person claiming under or through him shall be
          conclusively deemed to have indicated his acceptance and ratification
          of, and consent to, any action taken under the Plan by the Company,
          the Board or the Committee.

18.  AMENDMENT

     The Plan may be amended at any time and from time to time by the Board, but
     no amendment which increases the aggregate number of Shares which may be
     issued pursuant to the Plan or the class of employees eligible to
     participate shall be effective unless and until the same is approved by the
     shareholders of the Company. No

                                      I-19


     amendment of the Plan shall adversely affect any right of any participant
     with respect to any Award previously granted without such participant's
     written consent.

19.  TERMINATION

     This Plan shall terminate upon the earlier of the following dates or events
     to occur:

     (a)  the adoption of a resolution of the Board terminating the Plan; or

     (b)  ten years from the date the Plan is initially or subsequently approved
          and adopted by the shareholders of the Company in accordance with
          paragraph 20 hereof.

     No termination of the Plan shall alter or impair any of the rights or
     obligations of any person, without his consent, under any Award previously
     granted under the Plan.

                                                                   Exhibit 10.11

                         WHITE MOUNTAINS RE GROUP, LTD.
                                   ("WTM RE")
                          LONG TERM INCENTIVE UNIT PLAN
                                     SUMMARY

The purpose of the WTM Re Long Term Incentive Unit Plan (the "Plan") is to
provide long-term performance incentives for senior officers and other key
employees of the WTM Re companies and to align the interests of management with
those of White Mountains.

Participation in the Plan is discretionary based on annual recommendations by
WTM Re management as approved by the Board of Directors of WTM Re and its
subsidiaries. Performance achievement is measured over three consecutive year
periods. The first payout under the Plan will be in 2007. The final Plan
document is currently being drafted and will be approved by the Board of
Directors of the respective companies participating in the Plan. The Plan will
contain the following provisions:

UNIT AWARDS:
Participants are awarded Units with each Unit representing a value of $1,000.
There is the potential for the number of Units awarded to increase to a maximum
of 2 times the original award or decrease to zero depending upon the average
after-tax return on underwriting capital (as discussed below) over each three
year performance period. The ultimate value of each Unit is based upon the
consolidated results of the WTM Re.

MEASURING RETURNS:
The current performance target is a 13% after-tax return on underwriting capital
("UROC"). UROC is an amount of capital required to maintain the relevant rating
agency standard for each WTM Re entity. For example, the capital allocated to
Sirius International represents an amount of capital needed to maintain an "A"
level S&P rating.

The number of Units awarded will be reduced to zero at an average after-tax
return on UROC of 6% (the minimum return our owners expect on the capital) and
will be increased to a maximum of 2-times the original Unit award at an average
after-tax on UROC at or above 20%. The final dollar value of each Unit will also
be increased or decreased by the annual UROC compounded for each year in the
three-year cycle. The Board shall have the discretion to determine the standards
upon which the actual return on GAAP UROC are calculated including adjustments
to reflect standard investment income, internal and external debt interest, and
effective tax rates for each company within the group.


                                                                   Exhibit 10.13

                   WHITE MOUNTAINS RE GROUP LTD./FOLKSAMERICA
                                 2004 BONUS PLAN

The White Mountains Re Group Ltd./Folksamerica ("Companies") 2004 Bonus Plan is
intended to provide performance incentives for officers and other key employees.
Participation in the Plan is discretionary based on annual recommendations by
senior management.

The Plan earns a pool for payout when the Company meets pre-established goals
established for a given year. Participants target awards range from 10%-75% of
base salary ("Target") based on level of employment. Corporate goals for the
performance year 2004 are as follows:

THE 2004 CORPORATE PERFORMANCE TARGETS

The Annual Bonus generally follows the formula for the Companies Long Term
Incentive Plan. The returns required to achieve a bonus payout are based on
Underwriting Return On Capital ("UROC") deployed, as determined at the beginning
of the year.

After-Tax UROC -------------- Annual Goal for Target Payout 13% Min 6% Max 20%
Subject to individual achievements and officer level, participants earn a bonus payout based on the following: At 6% return on UROC, the payout is zero. At 20% return on UROC, the payout is two times the individual Target. Payouts between the minimum and the maximum returns stated above are pro-rated accordingly. Participation in the Plan and any right to receive a payout ceases when a participant ceases to be employed by the Companies.


                                                                   Exhibit 10.14

The validity of the Plan or any of its provisions shall be determined under, and it shall be construed and administered according to, the laws of the State of New York. ARTICLE VI DEFERRED COMPENSATION ACCOUNTS 6.1 ACCOUNTS. Amounts invested in any Investment Option may be transferred annually among any available Investment Option (including a transfer to/from the Phantom Share Investment Option) in accordance with procedures established by the Committee. Such transfer election may be made only within the 10-business day period commencing on the first business day of November of each year. An Investment Option election shall remain in effect for future Deferred Compensation (including amounts deferred in subsequent Plan Years) unless and until a new Investment Option Election is filed with the Committee. 6.2 ADJUSTMENTS TO ACCOUNTS. The balance in a Participant's Deferred Compensation Account at any time will be calculated on a daily basis by: (i) aggregating all current or prior Plan Years Deferred Compensation elected pursuant to ARTICLE IV; (ii) adding or subtracting thereto the cumulative interest equivalent, whether positive or negative, earned on such Deferred Compensation computed in accordance with the rules of Sections 6.3, 6.4 and 6.5.; and (iii) from such total obtained, subtracting the aggregate payments made to the Participant in current or prior Plan Years in accordance with ARTICLE VIII and ARTICLE X. 6.3 INVESTMENT OF DEFERRED COMPENSATION. Deferred Compensation shall be "theoretically invested" under any Investment Options described below as elected by the Participant. 6.4 PRIME RATE INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the Daily Prime Rate and (ii) the 4 Deferred Compensation balance existing as of the end of the previous day in the Prime Rate Investment Option, shall be credited each day to a Participant's Deferred Compensation Account. 6.4(a) DAILY PRIME RATE. Expressed as a percentage, the "Daily Prime Rate" as described in Section 6.4 will be calculated by dividing the "base rate" of interest announced publicly by Citibank, N.A. in New York, N.Y. (or the prime or base rate of another large commercial bank selected by the Committee), as in effect on the last business day of each month, by 360. 6.5 PHANTOM SHARE INVESTMENT OPTION. Interest equivalents shall be credited to or subtracted from amounts in the Phantom Share Investment Option on a daily basis. Such daily interest equivalents shall be equal to the product of (i) the aggregate number of Phantom Shares in a Participant's Phantom Share Investment Option at the close of business on the PRECEDING calendar day and (ii) an amount equal to (a) the Market Price of Shares on the current calendar day, plus (b) dividends paid or payable, as defined in Section 6.5(c), with respect to a single Share on such CURRENT calendar day, minus (c) the Market Price of Shares on the PRECEDING calendar day. For purposes of comparability, the above calculation shall be adjusted for any stock splits or stock dividends occurring during the current calendar day which affects the number of Phantom Shares a Participant held on the PRECEDING calendar day. 6.5(a) PHANTOM SHARES GRANTED TO PARTICIPANT. Unless the transition rule for exchanging existing stock rights applies (pursuant to Section 6.9), and subject to the Phantom Share Cumulative Dollar Limitation contained at Section 6.10(b), the number of Phantom Shares granted to a Participant will be determined by dividing the dollar amount of Deferred Compensation allocated to the Phantom Share Investment Option by the Conversion Price. Such total amount of Phantom Shares determined will then be rounded to the next one-tenth (1/10) Phantom Share. 6.5(b) CONVERSION PRICE. Other than Compensation being deferred pursuant to Section 6.9, the Conversion Price of Shares used to calculate the number of Phantom Shares to be added to a Participant's Deferred Compensation Account will be the closing Market Price of Shares at the end of the business day within the Plan Year where such Deferred Compensation would otherwise have been paid to the Participant if he had not elected to participate in the Plan. 6.5(c) DIVIDENDS REINVESTED IN PHANTOM SHARE INVESTMENT OPTION. For purposes of Section 6.5, dividends "paid or payable" shall mean either in cash or property, but shall exclude stock dividends or stock splits, as the case may be. Further, dividends paid or declared payable on the preceding day will be treated as automatically reinvested in Shares as of the end of such day at the closing Market Price of Shares; provided the Participant's account held Phantom Shares on the last day the Company declares as the date stockholders of record are entitled to receive such dividend on Shares (i.e., the "ex-dividend" date). 6.5(d) OTHER DILUTIVE AND ANTI-DILUTIVE TRANSACTIONS AFFECTING PHANTOM SHARES. In addition to Section 6.5(c), and subject to other provisions in the Plan, the Committee has the discretion to make appropriate adjustments to a Participant's account invested in the Phantom Share Investment Option where a "capital transaction" or "corporate reorganization" has the affect of changing the economic equivalent number of Phantom Shares that a Participant has been credited under the Plan. The Committee shall make an adjustment to each Participant's account so affected (if any), either positive or negative as the case may be, to ensure that neither unintended economic benefits nor detriments are conferred on a Participant solely by reason of such capital transaction or corporate reorganization. 6.5(e) CAPITAL TRANSACTION OR CORPORATE REORGANIZATION. Solely for purposes of Section 6.5(d), a "capital transaction" or "corporate reorganization" shall not be limited to its ordinary meaning if in fact a Participant would be conferred an economic benefit or detriment by some other corporate transaction which is not literally considered a capital transaction or corporate reorganization under common business usage of said terms. 6.6 EQUITY FUND INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the daily published total return for the Oakmark Fund and (ii) the Deferred Compensation balance existing as of the end of the previous day in the Equity 5 Fund Investment Option, shall be credited each day to a Participant's Deferred Compensation Account. 6.7 FIXED-INCOME FUND INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the daily published total return for the PIMCo Total Return Fund and (ii) the Deferred Compensation balance existing as of the end of the previous day in the Fixed-Income Fund Investment Option, shall be credited each day to a Participant's Deferred Compensation Account. 6.8 OTHER INVESTMENT OPTIONS. The Committee may make other Investment Options available under the Plan from time to time. Earnings (losses) shall be credited to (subtracted from) amounts invested in such other Investment Options on a daily basis as determined by the Committee. 6.9 TRANSITION RULE FOR CONVERTING EXISTING. RIGHTS (OR DERIVATIVE RIGHTS) TO SHARES. For purposes of establishing a Participant's Deferred Compensation Account, a transition rule shall apply for Participants electing to exchange and convert stock options, SARs, warrants and other rights to Shares (or derivative rights) granted pursuant to the Folksamerica Holding Company, Inc. Long-Term Incentive Plan or other contractual agreement between the Company and the Participant (collectively "Existing Options"). 6.9(a) ELECTION TO EXCHANGE AND CONVERT EXISTING OPTIONS. Eligible Participants can, upon written election, choose to exchange and convert their Existing Options either for Phantom Shares granted pursuant to this Plan and calculated as set forth in the "Phantom Share Conversion Formula" contained in Section 6.9(c) or alternatively, or in combination with the Phantom Share Conversion Option, elect to exchange and convert Existing Options into any other Investment Option allowed under the Plan, calculated as set forth in the "Dollar Equivalent Conversion Formula" contained in Section 6.9(d). Such conversion privilege is still subject to all other provisions of this Plan, including the minimum deferral rules of Article IV and Article VIII, the 365 day advance notice requirement in Section 4.2(ii) and the Phantom Share Cumulative Dollar Limitation in Section 6.10(b). 6.9(b) CONVERSION PRICE FOR EXCHANGING EXISTING OPTIONS. Solely for purposes of Section 6.9, and in addition to the irrevocable election to exchange and convert Existing Options pursuant to Section 6.9(a), the Conversion Price of Shares used to calculate the number of Phantom Shares to be added to a Participant's Deferred Compensation Account will be the closing Market Price of Shares at the end of the business day elected by the Participant and stated in the Deferred Compensation Election Form filed with the Committee. Each Participant must select one of two allowable dates to calculate the amount of Compensation being converted into this Plan: 1) the same date the election to irrevocably convert Existing Options is made pursuant to Section 6.9(a); or 2) Depending on the type of Compensation being converted, the appropriate "Trigger Date" as the term is defined in Section 4.2(ii). 6.9(c) PHANTOM SHARE CONVERSION FORMULA. ([$A - $B] /$A) x C SUB(sh) = D SUB(sh) Where $A = Conversion Price of Shares as defined in Section 6.5(b) or 6.9(b) Where $B = Weighted average exercise price for Shares under Existing Options Where C SUB(sh) Total Shares Participant could have purchased using Existing Options Where D SUB(sh)=Total Phantom Shares issued to Participant in exchange for Existing Options 6.9(d) DOLLAR EQUIVALENT CONVERSION FORMULA. 6 [$A - $B] x C SUB(sh)=$D Where $A = Conversion Price of Shares as defined in Section 6.5(b) or 6.9(b) Where $B = Weighted average exercise price for Shares under Existing Options Where SUB(sh) = Total Shares Participant could have purchased using Existing Options Where $D = Total Dollar Equivalent credited to the applicable Investment Option 6.9(e) LEGAL RIGHTS AFTER EXCHANGING EXISTING OPTIONS. Notwithstanding anything to the contrary, a Participant who makes an irrevocable election to convert Existing Options pursuant to Section 6.9 herein understands that they are forfeiting all legal rights to such Existing Options that they held immediately prior to making the election to convert such Existing Options into this Plan. 6.10 INVESTMENT OPTION ELECTION. Amounts invested in any Investment Option may be transferred annually among any available Investment Option (including a transfer to/from the Phantom Share Investment Option) in accordance with procedures established by the Committee. Such transfer election may be made only within the 10-business day period commencing on the third business day following release of the Company's third quarter financial information. An Investment Option election shall remain in effect for future Deferred Compensation (including amounts deferred in subsequent Plan Years) unless and until a new Investment Option Election is filed with the Committee. 6.10(a) INVESTMENT OPTION ALLOCATION. Subject to the Phantom Share Cumulative Dollar Limitation contained at Section 6.10(b), each Participant can elect to allocate each type of Deferred Compensation for a particular Plan Year among the available Investment Options as described in Sections 6.4, 6.5, 6.6, 6.7 and 6.8. However, if more than one Investment Option is selected for a type of Deferred Compensation such allocation cannot be less than $5,000 with respect to any one Investment Option so elected. 6.10(b) PHANTOM SHARE CUMULATIVE DOLLAR LIMITATION. Notwithstanding a Participant's ability to allocate Deferred Compensation among the available Investment Options, a Participant's election to invest Deferred Compensation in the Phantom Share Investment Option may be limited (either in whole or in part) as described hereupon separation from service due to either termination, normal retirement, death or disability; or (i) Without requiring authorization from the Board of Directors, but subject to all other provisions in this Plan, a Participant may continue to invest Deferred Compensation in the Phantom Share Investment Option to the extent the portion of a Participant's Deferred Compensation Account balance invested in the Phantom Share Investment Option does not have a fair market value which exceeds twenty million dollars ($20,000,000.00). (ii) Unless authorized by the Board of Directors, a Participant is precluded from investing additional Deferred Compensation in the Phantom Share Investment Option if the portion of a Participant's Deferred Compensation Account balance previously invested in the Phantom Share Investment Option has a fair market value which exceeds twenty million dollars ($20,000,000.00). 6.11 DELETION OF INVESTMENT OPTIONS. Except as provided in Section 15.2, the Committee cannot delete or alter the terms of an available Investment Option without the written permission of those Participants affected by such proposed amendment whose Deferred Compensation is invested in such Investment Option. 6.12 EFFECT ON OTHER PLANS. If, because of a Participant's deferral of Compensation under this Plan, a Participant's benefits in any other employee benefit plan of the Company (either qualified or nonqualified) are reduced, the Company shall provide a supplemental credit. Such supplemental credit however, shall not be provided through this Plan but through some other plan, agreement or other mechanism as the Committee deems appropriate. 7 ARTICLE VII PARTICIPANTS' RIGHTS UNSECURED 7.1 UNSECURED CREDITORS. Amounts credited to Deferred Compensation Accounts shall be dealt with in all respects as working capital of the Company. Therefore, the right of a Participant to receive any distribution hereunder shall be an unsecured claim against the general assets of the Company. 7.2 NO ACTUAL INVESTMENT REQUIRED. Subject to ARTICLE XVI, no assets of the Company shall in any way be held in trust for, or be subject to, any prior claim by a Director, an Officer, or a Key Employee, or his Beneficiary(ies) under the Plan. Further, neither the Company nor the Committee shall have any duty whatsoever to invest any amounts credited to any Deferred Compensation Accounts established under the Plan. ARTICLE VIII PAYMENT OF DEFERRED COMPENSATION 8.1 COMMENCEMENT OF BENEFITS. Subject to Section 8.1(a), when, and at the same time, an Eligible Participant elects to defer Compensation for any particular Plan Year, he shall also elect on the "Deferred Compensation Election Form" to have the portion of his Deferred Compensation Account balance attributable to such current Plan Year deferral commence to be paid on the first day of the Plan Year following the Plan Year in which the EARLIER event occurs: (i) upon separation from service due to either termination, normal retirement, death or disability; or (ii) upon the date such Participant attains a selected age. 8.1(a) 365 DAY MINIMUM DEFERRAL PERIOD. Notwithstanding the time elected for the commencement of benefits pursuant to Section 8.1, commencement of benefits will not occur prior to the expiration of a 365 day period beginning the day after the date on which an election to defer compensation became effective as provided in this Plan. 8.2 PAYMENT METHOD ELECTION. At the time the deferral election is filed pursuant to ARTICLE IV, Participants must also elect the method of receiving payment of their Deferred Compensation Account balance upon the first day of the Plan Year following the expiration of the elected deferral period. Each Participant shall elect to receive payment of their account either in: (i) one lump sum on the benefit commencement date; (ii) annual installments, with interest, over a specified period (determined in accordance with Section 8.3), beginning on the commencement date; or (iii) an annual installment/lump-sum combination where 25%, 50% or 75% of the Deferred Compensation Account balance is paid in annual installments over a specified period (determined in accordance with Section 8.3), beginning on the commencement date, and the remaining balance is paid in lump-sum, with accrued interest, at the end of the elected payment period. 8.2(a) INSTALLMENT PAYOUT FORMULA. If a Participant selects payment option (ii) or (iii) of Section 8.2, the annual installment amount for a particular Plan Year will be computed as follows: $W = ($X / [Y SUB(yr) - Z SUB(yr)] ) Where $W = Installment amount received by Participant in a particular Plan Year. Where $X = Participant's Deferred Compensation Account balance at the end of the prior Plan Year. 8 Where Y SUB(yr) = Number of years originally elected by Participant for the payment period. Where Z SUB(yr) = Number of years in the elected payment period already elapsed. 8.2(b) DEFERRAL ELECTION OVERRIDE. Notwithstanding anything contained herein to the contrary, with respect to any deferral election effective for Compensation earned after 1996, in the event that any amounts payable to a Participant hereunder (when aggregated with any other remuneration) would not be deductible by the Company as a result of Code Section 162(m), such amounts shall not be paid until the first Plan Year in which the amount would be deductible under Code Section 162(m). 8.3 PAYMENT PERIOD ELECTION. At the time an Eligible Participant elects to be a Participant for any Plan Year, he shall concurrently elect the number of years, up to a maximum of fifteen (15), over which his Deferred Compensation Account shall be paid out upon the expiration of the Deferral Period. 8.3(a) AUTOMATIC PAYMENT PERIOD OVERRIDE. Notwithstanding the Participant's payment period election pursuant to Section 8.3, in the case of termination for cause (Section 8.6) or death of a Participant (ARTICLE X), such payment period election will be automatically changed to the lump-sum option contained at Section 8.2(i). 8.4 PAYMENT DENOMINATION. All payments made to Participants shall be paid solely in cash. 8.5 CHANGE OF PRIOR ELECTIONS. Subject to the consent of the Committee, an Eligible Participant may file a request to change his prior election with respect to the timing of commencement of benefits (Section 8.1), payment method (Section 8.2) and/or payment period (Section 8.3). Such new election must be filed with the Committee at least 365 days prior to the date on which payment of benefits would commence under either the original or the revised election. Only one such request will be approved with respect to any Participant. 8.6 TERMINATION FOR CAUSE. Notwithstanding the payment period election made under Section 8.3, if a Participant is terminated for cause as determined by the Committee, payment of the entire amount remaining in his Deferred Compensation Account for all Plan Years shall be made in one lump sum on the first day after the end of the Plan Year in which termination occurred. Termination for cause shall include gross negligence, willful misconduct and fraud against the Company or any of its subsidiaries. 8.7 HARDSHIP WITHDRAWAL. Upon application of any Participant and approval thereof by the Committee, the Participant may withdraw, by reason of hardship, part or all of his Deferred Compensation Account. "Hardship" shall mean an unanticipated emergency situation in the Participant's financial affairs beyond the Participant's control, including illness or an accident involving the Participant, his dependents or other members of his family, or other significant financial emergency, as determined by the Committee in its sole discretion. 8.8 ACCRUED INTEREST PERIOD, For purposes of determining the benefits to be paid to Participants under ARTICLES VIII and X, interest on such Deferred Compensation Account balance will continue to accrue through the end of November in the Plan Year prior to the Plan Year in which payment of benefits will be made. Interest for the month of December in the Plan Year prior to the Plan Year in which payment of benefits will be made is calculated by using the following formula: [$X x Y% ] x 30 = $Z Where $X = Participant's Deferred Compensation Account balance at November 30th Where Y% = Daily Prime Rate (see Section 6.4(a)) in effect on November 30th Where $Z = Additional accrued interest due Participant for the month of December 9 ARTICLE IX VALUATION DATE 9.1 VALUATION. As of each Valuation Date, the Deferred Compensation Account of each Participant shall be valued by the Committee. The current value, and the change in value from the prior valuation (whether positive or negative), shall be communicated in writing to each Participant within forty-five (45) days after such Valuation Date. 9.2 VALUATION DATES. A Valuation Date shall, at a minimum, be four times during a Plan Year ending on each of the quarterly periods March 31, June 30, September 30 and December 31. ARTICLE X DEATH OF PARTICIPANT Notwithstanding the payment period election made under Section 8.3, a Participant's estate or designated Beneficiary shall be paid the value of his Deferred Compensation Account in one lump sum as of the first day after the end of the Plan Year in which his death occurred. Interest on such balance shall be determined in accordance with the rules contained in Section 8.8. ARTICLE XI ALIENATION Anticipation, alienation, sale, transfer, assignment, pledge or other encumbrance of any payments or benefits under the Plan shall not be permitted or recognized, and to the extent permitted by law, no such payments or benefits shall be subject to legal process or attachment for the payment of any claim of any person entitled to receive the same. ARTICLE XII TAX WITHHOLDING 12.1 WITHHOLDING. Subject to Sections 12.2 and 12.3, The Company shall deduct from all payments under this Plan each Participant's share of any taxes required to be withheld by any Federal, state or local government. The Participants and their Beneficiaries, distributees and personal representatives will bear any and all Federal, foreign, state, local income taxes or any other taxes imposed on Participants on amounts under this Plan. 12.2 FICA TAXES. Pursuant to Code Section 3121(v), Compensation deferred pursuant to this Plan is subject to FICA withholding at the time of deferral rather than at the time of distribution to the Participant. Accordingly, all Participants who have not yet reached the maximum compensation levels subject to FICA withholding at the time Compensation is deferred herein will be required to pay (by payroll deduction or check) to the Company the Participant's share of FICA taxes due and payable. 12.3 TAXES DUE AT DEFERRAL DATE OTHER THAN FICA TAXES. If any of the taxes referred to in Section 12.1 are due at the time of deferral, instead of at the time of payout, the Participant will be required to pay (by payroll deduction or check) to the Company the Participant's share of any such taxes then due and payable. ARTICLE XIII CONSENT By electing to become a Participant, each Director, Officer and Key Employee shall be deemed conclusively to have accepted and consented to all terms of the Plan and all actions or decisions made by the Company, the Board or the Committee with regard to the Plan. Such terms and consent shall also apply to, and be binding upon, the Beneficiaries, distributees and personal representatives and other successors in interest of each Participant. 10 ARTICLE XIV SEVERABILITY In the event any provision of this Plan would serve to invalidate the Plan, that provision shall be deemed to be null and void, and the Plan shall be construed as if it did not contain the particular provision that would make it invalid. ARTICLE XV AMENDMENT AND TERMINATION 15.1 BOARD MAY AMEND OR TERMINATE. Subject to Sections 15.2 and 15.3, the Board of Directors may at any time modify or amend any or all of the provisions of the Plan or may at any time terminate the Plan. 15.2 (i) INVESTMENT OPTIONS. Notwithstanding Section 15.1, the Board of Directors cannot delete or alter the terms of the Investment Options, contained herein at Sections 6.4, 6.5, 6.6, 6.7 and 6.8, without the written permission of those Participants, whose Deferred Compensation Account is invested in such Investment Option(s), who would be affected by such proposed amendment. However, nothing contained herein shall prevent the Board of Directors from substituting a new investment option for the Phantom Share Investment Option if the common stock of the Company (currently Shares) is not publicly traded on a nationally recognized stock exchange. In the event of such an occurrence, the Board of Directors shall have the sole authority to substitute a new Investment Option and allow only those Participants affected to transfer their Phantom Share account balance to another Investment Option if the substituted Investment Option is not acceptable to the particular Participant. (ii) FIDUCIARY GUIDELINES. Notwithstanding Section 15.1 and Section 15.2(i), the Board of Directors will not make amendments or terminate the Plan if such amendments or termination would reduce a Participant's balance in his Deterred Compensation Account. Further, the Board of Directors will not make amendments which would in any way eliminate the express requirement in Section 16.1 requiring the establishment of a Rabbi Trust in the event of a Change of Control if one has not previously been established. 15.3 TERMINATION. In the event of termination of the Plan, the Committee shall give written notice to each Participant that the entire balance in his Deferred Compensation Account will be distributed in the manner initially elected by each Participant pursuant to ARTICLE VIII. Further, pursuant to the responsibility vested with the Committee as stated in Section 17.1, the Committee will evaluate the advisability of establishing a Rabbi Trust, if one does not already exist, in light of the circumstances that caused the Board of Directors to terminate the Plan.

The assets of such trust shall at all times be subject to the claims of general creditors of the Company. Such contribution will be equal to the balance in each Participant's Deferred Compensation Account as of the Change of Control date.

Incumbent Board of Directors shall mean those individuals who, as of January 1, 1997, constituted the Board of Directors or, alternatively, those members elected or nominated after January 1, 1997 who were approved for such election or nomination by a vote of at least a majority of the directors then comprising the Incumbent Board of Directors. Further, individuals shall be excluded whose initial assumption of office is or was in connection with an actual or threatened election contest relating to the election of the directors of the Company (as used in rule 14a-11 under the Securities Exchange Act of 1934).

EMPLOYEE INSTRUCTIONS PERTAINING TO CONVERSION OF LONG-TERM INCENTIVE PLAN ("LTIP") AWARDS BEING CONVERTED TO THE PLAN PURSUANT TO SECTION 6.6 ________________________________________________________________________________ ________________________________________________________________________________ II. SIGNIFICANT PLAN LIMITATIONS 1. The minimum deferral for each type of compensation listed above is $5,000 for each Plan Year. 2. Dollar amounts must be in $5,000 increments for each type of compensation if deferral is less than 100%, of the total amount. 3. Percentages must be in 10% increments, subject to the $5,000 minimum rule (point #1) and $5,000 increment rule (point #2). 4. The $5,000 increment rule also applies to allocations between the four (4) investment options. 5. If base salary is being deferred, such total amount will be deducted pro rata from each paycheck. 7. An election to convert any outstanding LTIP awards must be made at least 365 days prior to the date the LTIP award either vests, becomes payable or expires, as the case may be.

Deferral of Performance Share payments in excess of Code Section 162(m) limits are mandatory for all participants.

Deferred Benefit Plan ARTICLE I PURPOSE OF PLAN 1.1 The purpose of this Plan is to provide eligible Officers and Key Employees of the Company and its subsidiaries with deferred retirement benefits. The Plan is also intended to establish a method of attracting and retaining persons whose abilities, experience and judgment can contribute to the long-term strategic objectives of the Company. 1.2 The Committee intends that the Plan be an unfunded non-qualified deferred compensation plan maintained primarily for the purpose of providing deferred retirement benefits for a select group of management or highly compensated employees of the Company and its subsidiaries, and that contributions to the Plan shall be deductible by the Company pursuant to Section 404(a)(5) of the Internal Revenue Code of 1986, as amended (the "Code").

ARTICLE III ELIGIBILITY Each Officer and Key Employee of the Company or any subsidiary which participates in the Plan, shall be eligible to participate in the Plan if selected by the Committee. The Committee has total discretion to determine who is eligible to participate on a Plan Year by Plan Year basis. ARTICLE IV PARTICIPATION 4.1 ELECTION FORM. Subject to Sections 4.2 and 4.3, an eligible Officer or Key Employee should make a valid election by executing and filing with the Committee, before the commencement of such Plan Year, a DEFERRED BENEFIT ELECTION FORM, a copy of which is attached hereto as EXHIBIT # 1. 4.2 NEW EMPLOYEES. Notwithstanding Section 4.1, a newly hired Officer or Key Employee who becomes a Participant after the first day of the current Plan Year may file a Deferred Benefit Election Form within fifteen (15) days after his initial date of employment with respect to the Deferred Retirement Benefit calculated on Compensation not yet earned for the remaining portion of the Plan Year. 4.3 DEFAULT ELECTIONS. If a Participant fails to file a timely Deferred Benefit Election Form in accordance with either Section 4.1 or 4.2, such Participant will forego all opportunity to make an Investment Option Election (Section 6.11), a Payment Method Election (Section 8.2) and a Payment Period Election (Section 8.3). Accordingly, failure to file a timely Deferred Benefit Election Form for a particular Plan Year will result in default elections being automatically triggered, which provide that: (i) the current Plan Year's calculated Deferred Retirement Benefit will be invested solely in the Prime Rate Investment Option; (ii) commencement of benefits will occur upon the first day of the Plan Year following the Plan Year in which termination of employment (for any reason) occurs; and (iii) the sole method of benefit payment to the Participant will be a lump sum. 4.4 ELECTION NOT REVOCABLE. Except as provided in Section 8.5, a Deferred Benefit Election Form, once executed and filed with the Committee, cannot be revoked for such current Plan Year's calculated Deferred Retirement Benefit. 4.5 VESTING. A Participant will be vested in his entire Deferred Benefit Account balance at all times and will not be subject to forfeiture for any reason. 4.6 PARTICIPATION IN DEFERRED COMPENSATION PLAN NOT REQUIRED. A Participant need not also participate in the Folksamerica Holding Company, Inc. Voluntary Deferred Compensation Plan in order to participate in this Plan for a particular Plan Year. 4.7 NEW ELECTIONS PERMITTED FOR EACH YEAR. All elections made on a Deferred Benefit Election Form for a particular Plan Year have no effect on, nor are affected by, elections made for future or past Plan Years. Each Plan Year election stands on its own. ARTICLE V GENERAL PROVISIONS 5.1 NO RIGHT TO PAYMENT EXCEPT AS PROVIDED IN PLAN. No Participant or Beneficiary shall have any right to any payment or benefit hereunder except to the extent provided in the Plan. 5.2 EMPLOYMENT RIGHTS. The employment rights of any Participant shall not be enlarged, guaranteed or affected by reason of the provisions of the Plan. 5.3 INITIAL PARTICIPATING COMPANIES. Currently, no subsidiary other than Folksamerica Reinsurance Company is permitted to participate in the Plan. However, the Committee can decide at a future date to allow inclusion of a new or previously excluded subsidiary(ies). 5.4 RECIPIENT UNDER A DISABILITY. If the Committee determines that any person to whom a payment is due hereunder is a minor, or is adjudicated incompetent by reason of physical or mental disability, the Committee shall have the power to cause the payments becoming due to such person to be made to the legal guardian for the benefit of the minor or incompetent, without responsibility of the Company or the Committee to see to the application of such payment, unless prior to such payment claim is made therefor by a duly appointed legal representative. Payments made pursuant to such power shall operate as a complete discharge of the Company and the Committee. 5.5 DESIGNATION OF BENEFICIARY. Each Participant may designate any person(s) or legal entity(ies), including his estate, as his Beneficiary under the Plan in writing to the Committee. A Participant may at any time revoke or change his designation of Beneficiary by writing to the Committee. If no person or legal entity shall be designated by a Participant as his Beneficiary, or if no designated Beneficiary survives him, his estate shall be his Beneficiary. 5.6 ELECTIONS. Any election made or notice given by a Participant pursuant to the Plan shall be in writing to the Committee, or to such representative as may be designated by the Committee for such purpose. Notice shall be deemed to have been made or given on the date received by the Committee or its designated representative. 5.7 CONTROLLING LAW. The validity of the Plan or any of its provisions shall be determined under, and it shall be construed and administered according to, the laws of the State of New York. ARTICLE VI DEFERRED BENEFIT ACCOUNTS 6.1 ACCOUNTS. Upon receipt of a Participant's valid Deferred Benefit Election Form, the Committee shall establish, as a bookkeeping entry only, a Deferred Benefit Account for such Participant. The Committee shall thereafter record to each Participant's Deferred Benefit Account, as of the last day of the previous Plan Year, the Deferred Retirement Benefit amount calculated pursuant to Section 6.3. 6.2 ADJUSTMENTS TO ACCOUNTS. The balance in a Participant's Deferred Benefit Account at any time will be calculated on a daily basis by: (i) aggregating all current or prior Plan Year Deferred Retirement Benefit amounts calculated pursuant to Section 6.3; (ii) adding (subtracting) thereto the cumulative interest equivalent, whether positive or negative, earned on such Deferred Retirement Benefit amounts computed in accordance with the rules of Sections 6.4, 6.5 and 6.6, 6.7 and 6.8; and (iii) from such total obtained, subtracting the aggregate payments made to the Participant in current or prior Plan Years in accordance with ARTICLE VIII and ARTICLE X. 6.4 INVESTMENT OF DEFERRED RETIREMENT BENEFITS. Deferred Retirement Benefit amounts shall be "theoretically invested" 6.3 DEFERRED RETIREMENT BENEFIT. A Participant's total Deferred Retirement Benefit amount for the current Plan Year shall be the sum of the following components, each of which is considered a separate Deferred Retirement Benefit solely for purposes of a Participant making an Investment Option Election pursuant to Section 6.11: (i) six percent (6%) of a Participant's Base Salary determined as of the beginning of a Plan Year, subject to an inflation adjusted, maximum annual dollar amoun as published by the Internal Revenue Service for a tax qualified plan commonly referred to as a 401(k) plan; and, (ii) the excess of: (a) the lump sum present value equivalent of the normal retirement benefit (i.e. a monthly annuity starting at age 65) computed as of the end of the CURRENT Plan Year, over (b) the lump sum present value equivalent of the normal retirement benefit computed as of the end of the PRIOR Plan Year. Solely for purposes of this Section 6.3(ii), the calculation of each Plan Year's normal retirement benefit shall employ recognized actuarial principles and such other reasonable assumptions deemed necessary by the Committee to achieve the stated objective of providing each Participant with a retirement benefit which approximates the benefit that a Participant would have been entitled under the Folksamerica Holding Company Retirement Plan, but assuming that the mandatory "Top Heavy" rules (i.e., internal revenue Code Sections 401 and 415) and maximum compensation limits imposed on all qualified plans do not exist. 6.3(a) PROSPECTIVE CATCH-UP ADJUSTMENT. In recognition of the fact that the calculation of the Deferred Retirement Benefit for a particular Plan Year is based on estimates made as of the beginning of a Plan Year as to what a Participant's Compensation will be for an entire Plan Year, a prospective catch-up adjustment, either positive or negative, shall be made if a Participant's actual Compensation differs from ESTIMATED Compensation. Accordingly, such difference will be considered an additional Deferred Retirement Benefit or Detriment, as the case may be, but will be taken into account solely in determining the Deferred Retirement Benefit amount for the Plan Year following the Plan Year to which the adjustment relates. 6.4 INVESTMENT OF DEFERRED RETIREMENT BENEFITS. Deferred Retirement Benefit amounts shall be "theoretically invested" under any of the investment Options described below, as elected by the Participant. 6.5 PRIME RATE INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the Daily Prime Rate and (ii) the portion of the Deferred Benefit Account balance existing as of the end of the previous day in the Prime Rate Investment Option, shall be credited each day to a Participant's Deferred Benefit Account. 6.5(a) DAILY PRIME RATE. Expressed as a percentage, the "Daily Prime Rate" as described in Section 6.5 will be calculated by dividing the "base rate" of interest announced publicly by Citibank, N.A. in New York, N.Y. (or the prime or base rate of another large commercial bank selected by the Committee), as in effect on the last business day of each month, by 360. 6.6 PHANTOM SHARE INVESTMENT OPTION. Interest equivalents shall be credited to (subtracted from) amounts in the Phantom Share Investment Option on a daily basis. Such daily interest equivalents shall be equal to the product of (i) the aggregate number of Phantom Shares in a Participant's Phantom Share Investment Option at the close of business on the PRECEDING calendar day and (ii) an amount equal to (a) the Market Price of Shares on the CURRENT calendar day, plus (b) dividends paid or payable, as defined in Section 6.5(c), with respect to a single Share on such CURRENT calendar day, minus (c) the Market Price of Shares on the PRECEDING calendar day. For purposes of comparability, the above calculation shall be adjusted for any stock splits or stock dividends occurring during the current calendar day which affects the number of Phantom Shares a Participant held on the PRECEDING calendar day. 6.6(a) PHANTOM SHARES GRANTED TO PARTICIPANT. Subject to the Phantom Share Cumulative Dollar Limitation contained at Section 6.11(b), the number of Phantom Shares granted to a Participant will be determined by dividing the dollar amount of Deferred Retirement Benefit allocated to the Phantom Share Investment Option by the Conversion Price. Such total amount of Phantom Shares determined will then be rounded to the next one-tenth (1/10) Phantom Share. 6.6(b) CONVERSION PRICE. The Conversion Price of Shares used to calculate the number of Phantom Shares to be added to a Participant's Deferred Benefit Account as of the beginning of a Plan Year will be the closing Market Price of Shares at the end of the last business day of the immediately preceding Plan Year. 6.6(c) DIVIDENDS REINVESTED IN PHANTOM SHARE INVESTMENT OPTION. For purposes of Section 6.6, dividends "paid or payable" shall mean either in cash or property, but shall exclude stock dividends or stock splits, as the case may be. Further, dividends paid or declared payable on the preceding day will be treated as automatically reinvested in Shares as of the end of such day at the closing Market Price of Shares; provided the Participant's account held Phantom Shares on the last day the Company declares as the date stockholders of record are entitled to receive such dividend on Shares (i.e. the "ex-dividend" date). 6.6(d) OTHER DILUTIVE AND ANTI-DILUTIVE TRANSACTIONS AFFECTING PHANTOM SHARES. In addition to Section 6.6(c), and subject to other provisions in the Plan, the Committee has the discretion to make appropriate adjustments to a Participant's account invested in the Phantom Share Investment Option where a "capital transaction" or "corporate reorganization" has the affect of changing the economic equivalent number of Phantom Shares that a Participant has been credited under this Plan. The Committee shall make an adjustment to the portion of each Participant's Deferred Benefit Account invested in the Phantom Share Investment Option so affected (if any), either positive or negative as the case may be, to ensure that neither unintended economic benefits nor detriments are conferred on a Participant solely by reason of such capital transaction or corporate reorganization. 6.6(e) CAPITAL TRANSACTION OR CORPORATE REORGANIZATION. Solely for purposes of Section 6.6(d), a "capital transaction" or "corporate reorganization" shall not be limited to its ordinary meaning if in fact a Participant would be conferred an economic benefit or detriment by some other corporate transaction which is not literally considered a capital transaction or corporate reorganization under common business usage of said terms. 6.7 EQUITY FUND INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the daily published total return for the Oakmark Fund and (ii) the Deferred Benefit Account balance existing as of the end of the previous day in the Equity Fund Investment Option, shall be credited each day to a Participant's Deferred Benefit Account. 6.8 FIXED-INCOME FUND INVESTMENT OPTION. Interest equivalents, equal to the product of (i) the daily published total return for the PIMCo Total Return Fund and (ii) the Deferred Benefit Account balance existing as of the end of the previous day in the Fixed-Income Fund Investment Option, shall be credited each day to a Participant's Deferred Benefit Account. 6.9 OTHER INVESTMENT OPTIONS. The Committee may make other Investment Options available under the Plan from time to time. Earnings (loss) shall be credited to (subtracted from) amounts invested in such other Investment Options on a daily basis as determined by the Committee. 6.10 INVESTMENT OPTION ELECTION. Amounts invested in any Investment Option may be transferred annually among any available Investment Options (including a transfer to/from the Phantom Share Investment Option) in accordance with procedures established by the Committee. Such transfer election may be made only within the 10-business day period commencing on the third business day following release of the Company's third quarter financial information. An Investment Option election shall remain in effect for future Deferred Compensation (including amounts deferred in subsequent Plan Years) unless and until a new Investment Option Election is filed with the Committee. 6.11(a) INVESTMENT OPTION ALLOCATION. Subject to the Phantom Share Cumulative Dollar Limitation contained at Section 6.11(b), each Participant can elect to allocate each component of a Plan Year's total Deferred Retirement Benefit among the available Investment Options as described in Sections 6.5, 6.6, 6.7, 6.8 and 6.9. 6.11(b) PHANTOM SHARE CUMULATIVE DOLLAR LIMITATION. Notwithstanding a Participant's ability to allocate Deferred Retirement Benefits for a Plan Year among the available Investment Options, a Participant's election to invest Deferred Retirement Benefits in the Phantom Share Investment Option may be limited (either in whole or in part) as described herein: (i) Without requiring authorization from the Board of Directors, but subject to all other provisions in this Plan, a Participant may continue to invest Deferred Retirement Benefits in the Phantom Share Investment Option to the extent the portion of a Participant's Deferred Benefit Account balance invested in the Phantom Share Investment Option does not have a fair market value which exceeds five million dollars ($5,000,000.00). (ii) Unless authorized by the Board of Directors, a Participant is precluded from investing additional Deferred Retirement Benefits in the Phantom Share Investment Option if the portion of a Participant's Deferred Benefit Account balance previously invested in the Phantom Share Investment Option has a fair market value which exceeds five million dollars ($5,000,000.00). 6.12 DELETION OF INVESTMENT OPTIONS. Except as provided in Section 15.2, the Committee cannot delete or alter the terms of an existing Investment Option without the written permission of those Participants affected by such proposed amendment whose Deferred Retirement Benefits is invested in such Investment Option. ARTICLE VII PARTICIPANTS' RIGHTS UNSECURED 7.1 UNSECURED CREDITORS. Amounts credited to Deferred Benefit Accounts shall be dealt with in all respects as working capital of the Company. Therefore the right of a Participant to receive any distribution hereunder shall be an unsecured claim against the general assets of the Company. 7.2 NO ACTUAL INVESTMENT REQUIRED. Subject to ARTICLE XVI, no assets of the Company shall in any way be held in trust for, or be subject to, any prior claim by an Officer or a Key Employee or his Beneficiary under the Plan. Further, neither the Company nor the Committee shall have any duty whatsoever to invest any amounts credited to any Deferred Benefit Accounts established under the Plan. ARTICLE VIII PAYMENT OF DEFERRED RETIREMENT BENEFITS 8.1 COMMENCEMENT OF BENEFITS. Subject to Sections 4.3 and 8.1(a), when, and at the same time, an eligible Participant elects to invest Deferred Retirement Benefits for any particular Plan Year, he shall also elect on the Deferred Retirement Benefits Election Form to have the portion of his Deferred Benefit Account balance attributable to such current Plan Year commence to be paid on the first day of the Plan Year following the Plan Year in which the EARLIER event occurs: (i) upon separation from service due to either termination, normal retirement, death or disability; or (ii) upon the date such Participant attains a selected age. 8.1 (a) 365 DAY MINIMUM DEFERRAL PERIOD. Notwithstanding the time for the commencement of benefits pursuant to Section 8.1, commencement of benefits will not occur prior to the expiration of a 365 day period beginning the day after the date on which a Deferred Retirement Benefit is awarded as provided in this Plan. (i) one lump sum on the benefit commencement date; 8.2 PAYMENT METHOD ELECTION. At the time the Deferred Benefit Election Form is filed pursuant to ARTICLE IV, Participants must also elect the method of receiving payment of their Deferred Benefit Account balance upon the first day of the Plan Year following the expiration of the elected Deferral Period. Each Participant shall elect to receive payment of his account either in: (ii) annual installments, with interest, over a specified period (determined in accordance with Section 8.3), beginning on the commencement date; or (iii) an annual installment/lump-sum combination where 25%, 50% or 75% of the Deferred Benefit Account balance is paid in annual installments over a specified period (determined in accordance with Section 8.3), beginning on the commencement date, and the remaining balance paid in lump-sum, with accrued interest, at the end of the elected payment period. 8.2(a) INSTALLMENT PAYOUT FORMULA. It a Participant selects payment option (ii) or (iii) of Section 8.2, the annual installment amount for a particular Plan Year will be computed as follows: $W = ($X / [Y SUB(yr) - Z SUB(yr)] ) Where $W = Installment amount paid to the Participant in a particular Plan Year. Where $X = The Participant's Deferred Benefit Account balance at end of the prior Plan Year. Where Y SUB(yr) = The number of years originally elected by the Participant for the payment period. Where Z SUB(yr) = The number of years in the elected payment period already elapsed. 8.2(b) DEFERRAL ELECTION OVERRIDE. Notwithstanding anything contained herein to the contrary, with respect to any deferral election effective for Compensation earned after 1996, in the event that any amounts payable to a Participant hereunder (when aggregated with any other remuneration) would not be deductible by the Company as a result of Section 162(m) of the Code, such amounts shall not be paid until the first Plan Year in which the amount would be deductible under Section 162(m) of the Code. 8.3 PAYMENT PERIOD ELECTION. At the time an Eligible Participant elects to be a Participant for any Plan Year, he shall concurrently elect on the Deferred Benefit Election Form the number of years, up to a maximum of fifteen (15), over which his Deferred Benefit Account shall be paid out upon the expiration of the Deferral Period. 8.3(a) AUTOMATIC PAYMENT PERIOD OVERRIDE. Notwithstanding the Participant's payment period election pursuant to Section 8.3, in the case of termination for cause (Section 8.6) or death of the Participant (ARTICLE X), such payment period election will be automatically changed to the lump-sum option contained at Section 8.2(i). 8.4 PAYMENT DENOMINATION. All payments made to Participants shall be paid solely in cash. 8.5 CHANGE OF PRIOR ELECTIONS. Subject to the consent of the Committee, a Participant may file a request to change his prior election with respect to the timing of commencement of benefits (Section 8.1), payment method (Section 8.2) and/or payment period (Section 8.3). Such new election must be filed with the Committee at least 365 days prior to the date on which payment of benefits would commence under either the original or the revised election. Only one such request will be approved with respect to any Participant. 8.6 TERMINATION FOR CAUSE. Notwithstanding the payment period election made under Section 8.3, if a Participant is terminated for cause as determined by the Committee, payment of the entire amount remaining in his Deferred Benefit Account for all Plan Years shall be made in one lump sum on the first day after the end of the Plan Year in which termination occurred. Termination for cause shall include gross negligence, willful misconduct and fraud against the Company or any of its subsidiaries. 8.7 HARDSHIP WITHDRAWAL. Upon application of any Participant and approval thereof by the Committee, the Participant may withdraw, by reason of hardship, part or all of his Deferred Benefit Account. "Hardship" shall mean an unanticipated emergency situation in the Participant's financial affairs beyond the Participant's control, including illness or an accident involving the Participant, his dependents or other members of his family, or other significant financial emergency, as determined by the Committee in its sole discretion. 8.8 ACCRUED INTEREST PERIOD. For purposes of determining the benefits to be paid to Participants under ARTICLES VIII and X, interest on such Deferred Benefit Account balance will continue to accrue through the end of November in the Plan Year prior to the Plan Year in which payment of benefits will be made. Interest for the month of December in the Plan Year prior to the Plan Year in which payment of benefits will be made is calculated by using the following formula: [$X x Y%]x30= $Z Where $X = Participant's Deferred Benefit Account balance at November 30th. Where Y% = Daily Prime Rate (see Section 6.5(a)) in effect on November 30th. Where $Z = Additional accrued interest due Participant for the month of December. ARTICLE IX VALUATION DATE 9.1 VALUATION. On each Valuation Date, the Deferred Benefit Account balance of each Participant shall be valued by the Committee. The current value, and the change in value from the prior Valuation Date (whether positive or negative), shall be communicated in writing to each Participant within forty-five (45) days after such Valuation Date. 9.2 VALUATION DATES. A Valuation Date shall, at a minimum, be four times during a Plan Year ending on each of the quarterly periods March 31, June 30, September 30 and December 31. ARTICLE X DEATH OF PARTICIPANT Notwithstanding the payment period election made under Section 8.3, a Participant's estate or designated Beneficiary shall be paid the value of his Deferred Benefit Account in one lump sum on the first day after the end of the Plan Year in which his death occurred. Interest on such balance shall be determined in accordance with the rules contained in Section 8.8. ARTICLE XI ALIENATION Other than as provided in ARTICLE X, anticipation, alienation, sale, transfer, assignment, pledge or other encumbrance of any payments or benefits under the Plan shall not be permitted or recognized, and to the extent permitted by law, no such payments or benefits shall be subject to legal process or attachment for the payment of any claim of any person entitled to receive the same. ARTICLE XII TAX WITHHOLDING 12.1 WITHHOLDING. Subject to Sections 12.2 and 12.3, the Company shall deduct from all payments under the Plan each Participant's share of any taxes required to be withheld by any Federal, state or local government. The Participants and their Beneficiaries, distributees and personal representatives will bear any and all Federal, FOREIGN, STATE, LOCAL INCOME TAXES OR ANY OTHER TAXES IMPOSED ON PARTICIPANTS ON AMOUNTS UNDER THIS PLAN. 12.2 FICA TAXES. Pursuant to Code Section 3121(v), Compensation deferred pursuant to the Plan is subject to FICA withholding at the time of deferral rather than at the time of distribution to the Participant. Accordingly, each Participant who has not yet reached the maximum compensation levels subject to FICA withholding at the time Compensation is deferred herein will be required to pay (by payroll deduction or check) to the Company his share of FICA taxes then due and payable. 12.3 TAXES DUE AT DEFERRAL DATE OTHER THAN FICA TAXES. If any of the taxes referred to in Section 12.1 are due at the time of deferral, instead of at the time of payout, the Participant will be required to pay (by payroll deduction or check) to the Company the Participant's share of any such taxes then due and payable. ARTICLE XIII CONSENT By electing to become a Participant, each Officer and Key Employee shall be deemed conclusively to have accepted and consented to all terms of the Plan and all actions or decisions made by the Company, the Board or the Committee with regard to the Plan. Such terms and consent shall also apply to, and be binding upon, the Beneficiaries, distributees and personal representatives and other successors in interest of each Participant. ARTICLE XIV SEVERABILITY In the event any provision of the Plan would serve to invalidate the Plan, that provision shall be deemed to be null and void, and the Plan shall be construed as if it did not contain the particular provision that would make it invalid. ARTICLE XV AMENDMENT AND TERMINATION 15.1 BOARD MAY AMEND OR TERMINATE. Subject to Sections 15.2 and 15.3, the Board of Directors, may at any time modify or amend any or ail of the provisions of the Plan or may at any time terminate the Plan. 15.2 (i) INVESTMENT OPTIONS. Notwithstanding Section 15.1, the Board of Directors cannot delete or alter the terms of the Investment Options, contained herein at Sections 6.5, 6.6, 6.7, 6.8 and6.9, without the written permission of those Participants whose Deferred Benefit Account is invested in such Investment Option(s) who would be affected by such proposed amendment. However, nothing contained herein shall prevent the Board Directors from substituting a new investment option for the Phantom Share Investment Option if the common stock of the Company (currently Shares) is not publicly traded on a nationally recognized stock exchange. In the event of such an occurrence, the Board of Directors shall have the sole authority to substitute a new Investment Option and allow only those Participants affected to transfer their Phantom Share account balance to another Investment Option if the substituted Investment Option is not acceptable to the particular Participant. (ii) FIDUCIARY GUIDELINES. Notwithstanding Section 15.1 and Section 15.2(i), the Board of Directors will not make amendments to or terminate the Plan if such amendments or termination would reduce a Participant's balance in his Deferred Benefit Account. Further, the Board of Directors will not make amendments which would in any way eliminate the express requirement in Section 16.1 requiring the establishment of a Rabbi Trust in the event of a Change of Control if one has not previously been established. 15.3 TERMINATION. In the event of termination of the Plan, the Committee shall give written notice to each Participant that the entire balance in his Deferred Benefit Account will be distributed in the manner initially elected by each Participant pursuant to ARTICLE VIII. Further, pursuant to the responsibility vested with the Committee as stated in Section 17.1, the Committee will evaluate the advisability of establishing a Rabbi Trust, if one does not already exist, in light of the circumstances that caused the Board of Directors to terminate the Plan. ARTICLE XVI CHANGE OF CONTROL 16.1 FUNDING OF TRUST. Notwithstanding ARTICLE VII, upon a "Change of Control" as defined in Section 16.2, the Board of Directors is required to cause the immediate contribution of funds to a trust, if not previously established (i.e. "Rabbi Trust" established in accordance with Rev. Proc. 92-64 (or any successor) or other funding mechanism approved by the Internal Revenue Service which would not result in Plan Participants being in constructive receipt of income), for the benefit of each Plan Participant, as beneficiary. The assets of such trust shall at all times be subject to the claims of general creditors of the Company. Such contribution will be equal to the balance in each Participant's Deferred Benefit Account as of the Change of Control date. Further, if the Plan is not terminated upon such Change of Control, the Company will continue to contribute to the trust, on an annual basis, an amount of cash equal to the Deferred Retirement Benefit awarded to each Participant after the Change of Control. 16.2 CHANGE OF CONTROL. For purposes of this Plan, a "Change of Control" shall occur if: (i) any person or group (within the meaning of Sections 13(d) and 14(d)(2) of the Securities Exchange Act of 1934), other than Fund American Enterprises Holdings, Inc. (through its affiliate White Mountains Holdings, Inc.), Folksam Mutual General Insurance Company, Wiener Staedtische Allgemeine Versicherung, P & V Assurances S.C., Forsikringsaktieselskapet Samvirke or the Company, becomes the beneficial owner (within the meaning of Rule 13d-3 under such Exchange Act) of fifty percent (50%) or more of the Company's then outstanding Shares; (ii) as defined in Section 16.3, the "Incumbent Board of Directors", cease to constitute a majority of the Board of Directors of the Company; or (iii) the business of the Company for which the Participant's services are principally performed is disposed of by the Company pursuant to a sale or other disposition of all or substantially all of the business or business related assets of the Company (including stock of a subsidiary of the Company). 16.3 INCUMBENT BOARD OF DIRECTORS. Incumbent Board of Directors shall mean those individuals who, as of January 1, 1997, constituted the Board of Directors or, alternatively, those members elected or nominated after January 1, 1997, who were approved for such election or nomination by a vote of at least a majority of the directors then comprising the Incumbent Board of Directors. Further, individuals shall be excluded whose initial assumption of office is or was in connection with an actual or threatened election contest relating to the election of the directors of the Company (as used in rule 14a-11 under the Securities Exchange Act of 1934). ARTICLE XVII PLAN ADMINISTRATION 17.1 COMMITTEE. The general administration of the Plan, the decision to establish a trust and the responsibility for carrying out its provisions shall be placed in the Committee. 17.2 DETERMINATIONS OF THE COMMITTEE. Subject to the limitations of the Plan, the Committee shall from time to time establish rules for the administration and interpretation of the Plan and the transaction of its business. The determination of the Committee as to any disputed question shall be conclusive. 17.3 MAJORITY VOTE. Any act which the Plan authorizes or requires the Committee to do may be done by a majority (expressed from time to time by a vote at a meeting or in writing without a meeting) and shall constitute the action of the Committee, and shall have the same effect for all purposes as if assented to by all members of the Committee. 17.4 AUTHORIZATION OF COMMITTEE MEMBERS. The members of the Committee may authorize one or more of their number to execute or deliver any instrument, make any payment, or perform any other act which the Plan authorizes or requires the Committee to do. 17.5 AGENTS. The Committee may employ or retain agents to perform such clerical, accounting, and other services as it may require in carrying out the provisions of the Plan. 17.6 Any and all such costs in administering this Plan will be paid and incurred by the Company. 17.7 NOTICES.

                      WHITE MOUNTAINS ANNUAL BONUS PROGRAM

Set forth below is a summary of the White Mountains Annual Bonus Program:

OVERVIEW

The White Mountains Annual Bonus Program (the "Program") is an integral part of
the total compensation program for employees of White Mountains Insurance Group,
Ltd. ("White Mountains") and certain of its subsidiaries. The Program is
overseen by the Compensation Committee of the Board of Directors of White
Mountains. At the end of each year, separate bonus pools are established for the
non-investment personnel and the investment personnel based on performance. In
general, the bonus pool may range from 0% to 200% of the target. Individual
awards from the bonus pool may vary widely based on individual performance.

ANNUAL BONUS POOL DETERMINATION

For non-investment personnel, the targeted annual bonus pool is the sum of the
individual target bonuses for participants in the program. For senior officers,
the individual target is 50% of salary; more junior personnel receive
progressively lower targets. At the beginning of each year, one or more
performance metrics are selected as the goal(s) for the bonus program. Typically
for White Mountains' non-investment personnel, the performance metric is growth
in intrinsic value per share. For corporate performance above or below target,
the annual bonus pool can range from 0% to 200% of the targeted annual bonus
pool.

For investment personnel, the size of the targeted annual bonus pool is
established in the same manner as for non-investment personnel with senior staff
having an individual target of 50% of salary and more junior staff having
progressively lower targets. Typically, performance is measured based upon
achievement of one or more of the following factors: (i) the absolute level of
investment results; (ii) investment performance as compared to a range of
relevant benchmarks; and (iii) peer company investment results. White Mountains
may also factor in corporate circumstances and its effect on pure investment
performance such as acquisition related portfolio purchases, repositioning of
the portfolio or other relevant matters. Based upon performance. the annual
bonus pool can range from 0% to 200% of the targeted annual bonus pool.

The Compensation Committee reserves the flexibility to adjust the size of an
annual bonus pool up or down as it deems appropriate given special
circumstances.

INDIVIDUAL AWARDS

Individual bonuses can vary widely around an annual bonus pool average based on
individual performance. No cap applies to the bonus any one participant can
receive as a percentage of salary.

A limited number of special bonuses may be awarded in any year to recognize
successful individual results without regard to the aggregate size of an annual
bonus pool.

PROGRAM PARTICIPATION FOR NEW HIRES

Annual bonuses of those eligible employees hired during the year are typically
pro-rated based on date of hire.



                                                                   Exhibit 10.23

                   ONEBEACON'S 2004 MANAGEMENT INCENTIVE PLAN

PURPOSE
The Management Incentive Plan (MIP) is an integral part of the total
compensation program for senior Home Office and Field Office management. Its
primary purpose is to focus attention on 2004 profitability goals and to reward
eligible participants for the achievement of those goals.

ELIGIBILITY
The Plan is limited to home office and field office senior staff who have a
significant impact on OneBeacon's operating results.

TARGET AWARDS
Target awards for all participants, expressed as a percent of salary, will be
set and approved by the Board of OneBeacon Corporation.

PERFORMANCE MEASURE
The Corporate MIP pool will be established based upon achievement of a 94%
combined ratio for total OneBeacon operations, computed on an adjusted calendar
year basis. This measurement will be used to establish a pool of money to be
allocated to business units and Home Office departments. At a corporate combined
ratio of 94%, the plan will fund an amount equal the sum of each of the plan's
participant's potential award at their target bonus percentage. The OneBeacon
Board of Directors may adjust the size of the pool based on under or over
achievement of the company's target combined ratio and the following objectives:
     -   Successful integration of Atlantic Mutual's commercial business into
         OneBeacon and the achievement of real growth and efficiencies in
         commercial lines.
     -   Successful deployment of our new personal insurance products and
         technology
     -   Continued profitable growth of our specialty businesses, including
         AutoOne and Skylands
     -   Continued claims savings and improved quality

INDIVIDUAL AWARDS
Each business unit will be judged against a number of metrics including, where
appropriate, a combined ratio result target, agreed to in advance with the
President of OneBeacon. Generally these targets will relate to the aggregate
financial plan rolled up by branch and line of business, but the targets will
not always match the plan (in many cases, the targets are more aggressive). If
the combined ratio target is achieved, in conjunction with other business
metrics, the business may be awarded 100% of its indicated share of the
corporate pool. Businesses failing to reach target may or may not, at the
discretion of the President, receive a reduced, partial allocation of the pool.
Businesses exceeding objectives may receive greater than 100% of indicated
allocation. In no event will the sum of the performance adjusted business unit
pools be greater than the performance adjusted company pool.

Within each business, it will be the prerogative of the business leader, with
guidance from and after consultation with the company President, to further
allocate the business's pool amount to the constituent branches, lines of
business and individuals, based upon performance against targets established
within the business. It will be the responsibility of the business leader, with

                                        1


guidance from the President, to establish appropriate targets for the
constituent branches, lines of business, departments, or individuals at the
outset of the MIP year.

For corporate or administrative functions that support all or multiple regions
or businesses, MIP individuals will receive allocations from the corporate pool
based upon attainment of their department and individual MIP goals for 2004.

Review and evaluation of performance will be conducted during the first quarter
following the end of the plan year. Incentive payments will be paid once plan
year results have been produced and evaluated.

The salary used to determine the amount of the individual awards will be that in
effect at the end of the plan year (12/31/04).

PLAN PARTICIPATION FOR NEW HIRES
Employees hired during the plan year are eligible to participate in the MIP.
Awards will be pro-rated specifically based on date of hire.

SPECIAL CIRCUMSTANCES
The OneBeacon Board of Directors may, in its sole discretion, also recognize
extraordinary conditions or circumstances in determining payment levels.

In the event of voluntary termination during a plan year or prior to the payment
of awards, other than retirement at the end of the plan year, no incentive
payment will be made. In the event of death or disability, the plan participant
or beneficiary may be considered for a partial award payment.

EFFECT ON BENEFIT PLANS
Amounts paid under the terms of this plan will not be counted for purposes of
determining compensation under any employee benefit plan sponsored by OneBeacon.

PLAN CONTINUATION
Notwithstanding any of the aforementioned, the plan may be amended or
terminated, in whole or in part, at any time, by the Board of Directors.

               Company, a New York reinsurance company ("FOLKSAMERICA"), and
               JOHN D. GILLESPIE, an individual resident of the State of
               Connecticut (the "INVESTMENT MANAGER").

          WHEREAS the Acquisition Company and the Investment Manager desire to
enter into an agreement under which (i) the Acquisition Company and the
Investment Manager shall share the revenue of Prospector Partners, L.L.C.
("PROSPECTOR PARTNERS"), and Prospector Associates, L.L.C. ("PROSPECTOR
ASSOCIATES"), and (ii) the Acquisition Company shall pay the expenses of
Prospector Partners during the Agreement Term (as defined below); and

          WHEREAS Folksamerica and the Investment Manager desire to enter into
an agreement under which Folksamerica shall receive a founder's revenue share
(the "FOUNDER'S REVENUE SHARE") in respect of revenue of certain businesses of
the Investment Manager as provided herein.

          NOW, THEREFORE, in consideration of the mutual covenants contained
herein and intending to be legally bound hereby, the parties hereto hereby agree
as follows:

          SECTION 1. TERM. The Acquisition Company's responsibility for the
expenses of Prospector Partners and the sharing of the revenue of Prospector
Partners and Prospector Associates by the Acquisition Company under the terms of
Sections 2, 3, 4 and 5 hereof shall commence on January 1, 2001 (the
"COMMENCEMENT DATE"), and shall remain in effect until any written notice of
termination of the separate agreement between the Acquisition Company and John
D. Gillespie (the "SEPARATE AGREEMENT"), dated as of the date of the Acquisition
Company's acquisition (the "ACQUISITION") of CGU Corporation, a Delaware
corporation, shall be given as required under Section 2 thereof; provided,
however, that the provisions of Sections 2, 3, 4 and 5 of this Agreement shall

period of time between the Commencement Date and the termination of such
provisions pursuant to the terms of this Agreement is herein referred to as the
"AGREEMENT TERM".

          SECTION 2. SHARING OF REVENUE. (a) The Investment Manager shall (i)
pay or cause to be paid to the Acquisition Company out of any amounts allocable
to him from the gross revenue of Prospector Partners and Prospector Associates
in respect of each calendar year, no later than 30 days after the issuance of
audited financial statements for Prospector Partners Fund, L.P., Prospector
Partners Small Cap Fund, L.P., and Prospector Offshore Fund (Bermuda), Ltd., and
any other fund that the Investment Manager shall be actively involved in the
investment management during the Agreement Term (hereinafter any such funds

                                                                              2

referred to as the "FUNDS" and individually referred to as a "FUND"), in respect
of such year, or, at his discretion, (ii) cause to be allocated, as of the last
day of such year, to any capital account of the Acquisition Company in any of
the Funds out of amounts otherwise allocable to any of the Investment Manager's
capital accounts in any of the Funds in respect of such year, or (iii) shall

Investment Manager may pay or cause to be paid to the Acquisition Company, at
any time in any calendar year during the Agreement Term, the Acquisition
Company's share, or any portion of its share, of the Net Revenue for such year
on an estimated basis. If the total amount paid to the Acquisition Company under
this paragraph (a) in respect of any year shall exceed the Acquisition Company's
share of Net Revenue for such year as finally determined, the Acquisition
Company shall return such excess to the Investment Manager within 30 days of
such final determination. The "Applicable Percentage" shall be 50%; provided,
however, that with respect to any year or portion of a year in which Kevin

shall be 33%. "NET REVENUE" shall be calculated annually on a calendar year
basis and shall mean the sum of (i) the aggregate gross revenue earned by
Prospector Associates and Prospector Partners during any such year in respect of

of the Funds), and (ii) gross revenue earned by Prospector Partners during such
year in respect of accounts managed by Prospector Partners during the Agreement
Term that are not accounts of any Fund (hereinafter any such accounts shall be
referred to collectively as the "SEPARATE ACCOUNTS" and individually as a
"SEPARATE ACCOUNT"). Notwithstanding anything in the foregoing provisions of
this paragraph to the contrary, the aforementioned definition of Net Revenue
shall not include, (a) with respect to each share of convertible preferred stock
in White Mountains Insurance Group, Ltd., a Bermuda company ("WHITE MOUNTAINS"),
offered in connection with the Acquisition and subscribed to by any Fund or
Separate Account prior to the Acquisition, the excess of $319 over the per share
value at the time of subscription, as determined pursuant to the agreement under
which such shares shall have been subscribed to, (b)(i) any amounts or interests
earned or accrued prior to the Commencement Date, including amounts or interests
earned but not yet paid in respect of Prospector Offshore Fund (Bermuda), Ltd.,
and any investment earnings in respect thereof, and (ii) the Investment
Manager's pro rata share of investment earnings in respect of amounts earned or
accrued, but not yet paid, subsequent to the Commencement Date in respect of
Prospector Offshore Fund (Bermuda), Ltd., and (c) any amounts or interests
earned in respect of any capital account in any of the Funds, or any Separate
Account, owned by the Investment Manager, any member of Prospector Associates or
Prospector Partners and any of the Investment Manager's, or any such member's,
immediate family members or related entities.

          (b) Additionally, during the Agreement Term, the Investment Manager
shall pay or cause to be paid to the Acquisition Company 25% of his allocable
share of the amount that the aggregate cumulative distributions paid to the
Connecticut Fund Business Entities (as hereinafter defined) shall exceed $3
million during the Agreement Term. Such 25% shall be calculated and paid
annually on a calendar year basis no later than 30 days after the issuance of
audited financial



                                                                               3

statements for such entities in respect of each calendar year during the
Agreement Term. The "CONNECTICUT FUND BUSINESS" shall mean the business
activities of the Connecticut Fund Business Entities (as hereinafter defined) in
respect of investments under the Connecticut Insurance Reinvestment Act No.
97-292. The "CONNECTICUT FUND BUSINESS ENTITIES" shall include: (i) Insurance
Capital Partners, LLC; (ii) Olmstead Capital Partners, LLC; (iii) Prospector
Capital Management, LLC; (iv) Prospector Partners CT Fund Investment Management,
LLC; and (v) Prospector Capital Management II, LLC.

          SECTION 3. EXPENSES. In consideration of the Investment Manager
agreeing to the terms of Section 2 hereof, during the Agreement Term the
Acquisition Company shall be responsible for, and shall pay or cause to be paid
on a timely basis, all expenses of Prospector Partners including, but not
limited to, (a) employee compensation (including salaries, incentive bonuses and
employee benefits), other than the Investment Manager's compensation, (b) rents,
(c) any costs associated with relocating the business office, including
leasehold improvements, purchases of office equipment, and furniture,
furnishings and fixtures and (d) any expenses incurred in connection with the
operations of Prospector Partners. The Acquisition Company and the Investment
Manager understand that Prospector Partners expects to hire one or more
additional employees with superior talent and credentials in investment
management activities, and such other support employees as the Investment
Manager deems advisable, and that the salary and any incentive bonus of any such
employee, including any share of Net Revenue of any such employee hired to
conduct investment management activities, shall be included as part of the
expenses the Acquisition Company agrees to pay hereunder.

          SECTION 4. ADDITIONAL INVESTMENTS BY THE ACQUISITION COMPANY. (a) The
Acquisition Company, or any wholly owned affiliate or affiliates of the
Acquisition Company or White Mountains, shall make capital contributions to any
Fund or Separate Account to replace any capital committed to such Fund or
Separate Account as of the date of the public announcement by either the
Acquisition Company or the Investment Manager, or by White Mountains, of the
services to be performed by the Investment Manager pursuant to the Separate
Agreement that shall be withdrawn from such Fund or Separate Account prior to
the second anniversary of the date of such public announcement, in each case as
a result of the Investment Manager committing to provide such services. Any
withdrawal of such committed capital made after the first anniversary and prior
to the second anniversary of such date shall be considered to have been made as
a result of the Investment Manager committing to provide such services if the
individual or entity making such withdrawal shall confirm in writing that such
withdrawal shall have been a result of such commitment.

          (b) If, during the Agreement Term, the Acquisition Company or any of
its affiliates shall desire to place any amount not under the investment
management of Prospector Partners on the Commencement Date under the investment
management of Prospector Partners, such amount shall not be invested in any of
the Funds (other than as an allocation of the Acquisition Company's share of Net
Revenue as provided in paragraph (a) of Section 2 hereof or as a replacement of
withdrawn capital as provided in the foregoing paragraph of this Section 4) but
a Separate Account shall be created by Prospector Partners for each such amount
under the same terms and conditions of the 1% fee paying Separate Accounts
existing on the Commencement Date.



                                                                               4

          SECTION 5. PAYMENT UPON TERMINATION. Following the conclusion of the
Agreement Term, the Acquisition Company (i) shall be entitled to any payment or
allocation pursuant to and under the terms of paragraph (a) of Section 2 hereof
that shall not yet have been paid or allocated but that the Acquisition Company
shall have been entitled to if the Agreement Term had continued until the end of
the year in which such termination shall have occurred, and (ii) shall pay or
cause to be paid on a timely basis all expenses of Prospector Partners that
shall have accrued prior to the conclusion of the Agreement Term but that shall
not yet have been paid.

          SECTION 6. TERMINATION; SURVIVAL. The provisions of Sections 2, 3, 4
and 5 of this Agreement shall terminate upon the giving of written notice of
termination of the Separate Agreement by either party thereto, as required under
Section 2 thereof. The provisions of Section 7 of this Agreement shall terminate
upon the mutual written consent of Folksamerica and the Investment Manager.
Notwithstanding the foregoing, Sections 5 and 8 of this Agreement shall survive
the termination of any provisions of this Agreement.

          SECTION 7. PAYMENT OF FOUNDER'S REVENUE SHARE. (a) The Investment
Manager shall pay the Founder's Revenue Share (if any) in respect of each
calendar year to Folksamerica, no later than 30 days after the issuance of
audited financial statements for Prospector Partners Fund, L.P., Prospector
Partners Small Cap Fund, L.P., and Prospector Offshore Fund (Bermuda), Ltd.
(hereinafter such funds shall collectively be referred to as the "ORIGINAL
FUNDS"). The Founder's Revenue Share in respect of any calendar year shall be
the amount (if any) equal to the Founder's Revenue Share Percentage (as defined
below) multiplied by the excess (if any) of (i) the sum of the gross revenues of
Prospector Partners and of Prospector Associates in respect of such year to the
extent such revenues are allocable to one or more of the Original Funds (and not
allocable to a separately managed account or other investment management
activity) over (ii) Five hundred thousand (500,000).

          (b) The "FOUNDER'S REVENUE SHARE PERCENTAGE" shall initially be six
percent (6%). If Folksamerica withdraws all or any part of its original
$10,000,000.00 investment in the Funds (including a withdrawal of all or any
part of earnings and/or appreciation in respect of such original investment),
the Founder's Revenue Share Percentage or a segregated portion thereof, as
determined below, shall be reduced by the amount equal to one-third of the
Founder's Revenue Share Percentage or the segregated portion thereof, as the
case may be, at the time of such withdrawal per year for each year beginning
with the calendar year of withdrawal until the Founder's Revenue Share
Percentage or segregated portion thereof, as the case may be, shall be reduced
to zero. For purposes of the preceding sentence, in the event Folksamerica
withdraws less than all of its original $10,000,000.00 investment in the Funds
(including a withdrawal of less than all the earnings and/or appreciation in
respect of such original investment) only that portion of the Founder's Revenue
Share Percentage that bears the same ratio to the entire Founder's Revenue Share
Percentage as the amount of the withdrawal bears to the total investment of
Folksamerica at the time of such withdrawal (including earnings and appreciation
thereon) shall be subject to reduction as provided by the foregoing provisions
of this paragraph (b), and the Founder's Revenue Share Percentage shall be
divided and segregated for purposes of identifying the portion thereof subject
to reduction. The Founder's Revenue Share Percentage shall be reduced from time
to time to take into account any reduction in the Founder's Revenue



                                                                               5

Share Percentage and/or any segregated portion thereof pursuant to the
provisions of this paragraph.

          SECTION 8. MISCELLANEOUS. (a) This Agreement shall inure to the
benefit of (i) the Investment Manager and his executors, administrators, heirs,
personal representatives and permitted assigns, (ii) the Acquisition Company and
its successors and permitted assigns and (iii) Folksamerica and its successors
and permitted assigns; provided, however, that except as provided herein, the
Investment Manager shall not be entitled to assign or delegate any of his rights
or obligations in respect of Sections 2, 4 and 5 hereunder without the prior
written consent of the Acquisition Company or his rights or obligations in
respect of Section 7 hereunder without the prior written consent of
Folksamerica; and each of the Acquisition Company and Folksamerica shall be
permitted to assign its interests and obligations under this agreement to any
wholly owned affiliate of the Acquisition Company or White Mountains at anytime
with the prior written consent of the Investment Manager, such consent not to be
unreasonable withheld.

          (b) This Agreement shall be deemed to be made in, and in all respects
shall be interpreted, construed and governed by and in accordance with, the laws
of the State of New York, without regard to the conflicts of law principles of
such State. No provision of this Agreement or any related document shall be
construed against or interpreted to the disadvantage of any party hereto by any
court or other governmental or judicial authority by reason of such party having
or being deemed to have structured or drafted such provision.

          (c) This Agreement constitutes the entire agreement between and among
the Acquisition Company, Folksamerica and the Investment Manager with respect to
the responsibility for the expenses of Prospector Partners, the sharing of
revenue of Prospector Partners and Prospector Associates by the Acquisition
Company and the Investment Manager, and the payment of the Founder's Revenue
Share and, effective as of the Commencement Date, supersedes all prior
agreements, if any, whether written or oral, between and among the Acquisition
Company, Folksamerica and the Investment Manager with respect to such matters.

          IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be duly executed as of the day and year first above written.

                      WHITE MOUNTAINS INSURANCE GROUP, LTD.

                            CODE OF BUSINESS CONDUCT

INTRODUCTION

       It is the policy of White Mountains Insurance Group, Ltd. and its
subsidiaries (the "Company") to be lawful and highly-principled in all our
business practices.

       This Code of Business Conduct (this "Code") applies to all directors,
officers, and employees of the Company (collectively, "Covered Persons") and
covers a wide range of business practices and procedures. In addition, the
Company expects consultants and advisors to the Company to adhere to the
relevant principles of this Code in connection with their activities for the
Company. This Code does not purport to address every issue or situation that may
arise, but sets out basic principles that should govern the day-to-day business
behavior of Covered Persons. All Covered Persons must conduct themselves
accordingly and seek to avoid even the appearance of improper behavior. If
something seems improper, it likely is. The Company expects each Covered Person
to review this Code and to follow both the letter and spirit of the standards
and policies contained herein. Always remember: if you are unsure of what to do
in any situation, seek guidance before you act.

       All Covered Persons are expected to seek the advice of their supervisor,
manager or other appropriate persons within the Company when questions arise
about issues discussed in this Code and any other issues that may implicate the
standards or integrity of the Company or any Covered Person. Compliance
procedures are set forth in Section 13 of this Code.

       Taking actions to prevent problems is part of the Company's culture. If
you observe possible questionable or illegal conduct you are encouraged to
report your concerns. If you report, in good faith, what you suspect to be
illegal or improper activities, you should not be concerned about retaliation
from others. Any Covered Persons involved in retaliation will be subject to
serious disciplinary action by the Company.

       Those who violate the standards in this Code will be subject to
disciplinary action, including dismissal for cause. COVERED PERSONS WHO FIND
THEMSELVES IN A SITUATION WHICH THEY BELIEVE MAY VIOLATE OR LEAD TO A VIOLATION
OF THIS CODE, SHOULD FOLLOW THE GUIDELINES DESCRIBED IN SECTION 13 OF THIS CODE.

1.     COMPLIANCE WITH LAWS, RULES AND REGULATIONS

       The Company shall transact its business in compliance with all applicable
laws, rules and regulations.

2.     CORPORATE OPPORTUNITIES

       Covered Persons owe a duty to the Company to advance its legitimate
interests when the opportunity to do so arises. Covered Persons are prohibited
(without the consent of the Board of Directors or a designated committee
thereof) from (1) taking for themselves personally opportunities that are
discovered through the use of corporate property, information or their position,
(2) using corporate property, information or their position for personal gain
and (3) competing with the Company directly or indirectly. The Company
recognizes that the guideline



in this clause (3) of the prior sentence should not restrict Covered Persons who
are not employed by the Company ("Outside Persons"). In the case of directors of
the Company, these principles are intended to be identical to the comparable
fiduciary obligations directors already owe the Company.

3.     CONFLICTS OF INTEREST

       A "conflict of interest" exists when a person's private interest
interferes in any way with the interests of the Company.

       A conflict situation can arise when a Covered Person takes actions or has
interests that may make it difficult to perform his or her Company work
objectively and effectively. Conflicts of interest also arise when a Covered
Person or a member of his or her family, receives improper personal benefits
(including personal loans, services or payment for services that the person is
performing in the course of Company business) as a result of his or her position
in the Company or gains personal enrichment through access to confidential
information.

       Conflicts of interest can arise in many common situations, despite one's
best efforts to avoid them. Covered Persons are encouraged to seek clarification
of, and discuss questions about, potential conflicts of interest with someone in
the Company's Legal Department. Covered Persons may also contact the Company's:

                  Code of Business Conduct Compliance Officer:
                  Tel: (603) 640-2200
                  Fax: (603) 640-2250

       Any Covered Person who becomes aware of a conflict or potential conflict
should bring it to the attention of a supervisor, manager or other appropriate
persons within the Company.

4.     INSIDER TRADING

       There are instances where Covered Persons have information about the
Company, its subsidiaries or affiliates or about a company with which we do
business that is not known to the investing public. Such inside information may
relate to, among other things: plans; new products; mergers, acquisitions or
dispositions of businesses or securities; problems facing the Company or a
company with which we do business; reserves; profitability; negotiations
relating to significant contracts or business relationships; significant
litigation; or financial information.

       If the information is such that a reasonable investor would consider the
information important in reaching an investment decision, then the Covered
Person who holds the information must not buy or sell Company securities, nor
provide such information to others, until such information becomes public.
Further, Covered Persons must not buy or sell securities in any other company
about which they have such material non-public information, nor provide such
information to others, until such information becomes public. Covered Persons
who involve themselves in illegal insider trading (either by personally engaging
in the trading or by disclosing material non-public information to others) will
be subject to immediate termination. The Company's policy is to report such
violations to the appropriate authorities and to cooperate fully in any
investigation of insider trading.

                                        2


       The Company has additional, specific rules that govern trades in Company
securities by directors, officers and employees. Please refer to the Company's
Insider Trading Policy.

       Covered Persons may need assistance in determining how the rules
governing inside information apply to specific situations and should consult
someone in the Company's Legal Department or the Company's Code of Business
Conduct Compliance Officer.

5.     COMPETITION AND FAIR DEALING

       Our policy is to compete vigorously, aggressively and successfully by all
legal means in today's increasingly competitive business climate and to do so in
compliance with all applicable competition, fair dealing and other laws in all
the markets in which we operate. Stealing proprietary information or trade
secret information or inducing such disclosures by past or present employees of
other companies is prohibited. Each Covered Person should endeavor to deal
fairly with the Company's customers and employees.

       The antitrust laws of many jurisdictions are designed to preserve a
competitive economy and promote fair and vigorous competition. All Covered
Persons are required to comply with these laws and regulations. Covered Persons
involved in marketing, sales and purchasing, contracts or in discussions with
competitors have a particular responsibility to ensure that they understand our
standards and are familiar with applicable competition laws. Because these laws
are complex and can vary from one jurisdiction to another, Covered Persons
should seek the advice of the Company's Legal Department when questions arise.

6.     GIFTS AND ENTERTAINMENT

       The purpose of business gifts and entertainment in a commercial setting
is to create good will and sound working relationships, not to gain unfair
advantage with customers. No gift or entertainment should ever be offered,
given, provided or accepted by any Covered Person, family member of a Covered
Person or agent unless it: (1) is consistent with customary business practices,
(2) is not excessive in value, (3) cannot be construed as a bribe or payoff and
(4) does not violate any laws or regulations. Please discuss with your
supervisor any gifts or proposed gifts unless you are certain they are
appropriate.

7.     DISCRIMINATION AND HARASSMENT; HUMAN RESOURCES PRACTICES

       We are firmly committed to providing equal employment opportunities to
all individuals and will not tolerate any illegal discrimination or harassment.
Examples include derogatory comments based on age, race, gender or ethnic
characteristics and unwelcome sexual advances or comments. This policy extends
to all areas of employment including hiring, training, compensation, promotion,
discipline, transfer, layoff, termination and all other items and conditions of
employment. All Covered Persons shall be treated with respect and consideration
from the Company and must treat others in the same manner.

       All levels of supervision are responsible for monitoring and complying
with the Company's policies and procedures for handling complaints concerning
harassment or other forms of unlawful discrimination. Because employment-related
laws are complex and vary from state to state and country to country,
supervisors should obtain the advice of the Company's Legal Department whenever
there is any doubt as to the lawfulness of any proposed action or inaction.

       The Company strives to provide each employee with a safe and healthy work
environment. Each Covered Person has responsibility for maintaining a safe and
healthy

                                        3


workplace for all Covered Persons by following safety and health rules and
practices and reporting accidents, injuries and unsafe equipment, practices or
conditions.

       Violence and physically threatening behavior is expressly prohibited.
Covered Persons should report to work in condition to perform their duties, free
from the influence of illegal drugs or alcohol. The use of alcohol or illegal
drugs in the workplace will not be tolerated and may result in immediate
termination.

8.     RECORD-KEEPING, RETENTION AND DESTRUCTION

       Many persons within the Company record or prepare some type of
information during their workday, such as time cards, financial reports,
accounting records, business plans, environmental reports, injury and accident
reports, expense reports, and so on. Many people, both within and outside the
Company, depend upon these reports to be accurate and truthful for a variety of
reasons. These people include our Covered Persons, governmental agencies,
auditors and the communities in which we operate. Also, the Company requires
honest and accurate recording and reporting of information in order to make
responsible business decisions. We maintain the highest commitment to recording
information accurately and truthfully.

       All financial statements and books, records and accounts of the Company
must accurately reflect transactions and events and conform both to required
legal requirements and accounting principles and also to the Company's system of
internal accounting. As a Covered Person, you have the responsibility to ensure
that false or intentionally misleading entries are not made by you, or anyone
who reports to you, in the Company's accounting records. Regardless of whether
reporting is required by law, dishonest reporting within the Company, or to
organizations or people outside the Company, is strictly prohibited. All Covered
Persons that are responsible for financial or accounting matters are also
required to ensure the full, fair, accurate, timely and understandable
disclosure in all periodic reports required to by filed by the Company with the
Securities and Exchange Commission. This commitment and responsibility extends
to the highest levels of our organization, including our chief executive
officer, chief financial officer and chief accounting officer.

       The Company establishes retention or destruction policies in order to
ensure legal compliance and also to accomplish other objectives, such as
preserving intellectual property and cost management. The Company expects all
Covered Persons to comply with any applicable records retention or destruction
policy, provided that all Covered Persons should note the following general
exception to any record retention or destruction policy. If any Covered Person
believes, or if the Company informs him or her, that the Company's records are
relevant to any litigation or potential litigation (i.e. a dispute that could
result in litigation), he or she must preserve those records until the Company's
General Counsel or another authorized legal officer determines the records are
no longer needed. This exception supersedes any previously or subsequently
established retention or destruction policy for those records.

       The Company recognizes that the guidelines in this Section 8 are not
applicable to Outside Persons.

9.     CONFIDENTIALITY

       Covered Persons must maintain the confidentiality of confidential
information entrusted to them by the Company or companies, organisations or
entities that have or may have a business relationship with the Company, except
when disclosure is expressly authorized by the Company or required by laws or
regulations. Confidential information includes all non-public information that
might be of use to competitors, or harmful to the Company or companies,
organisations or

                                        4


entities that have or may have a business relationship with the Company, if
disclosed. It also includes information that others that have a business
relationship with the Company have entrusted to us. The obligation to preserve
confidential information continues even after employment ends.

       Covered Persons should guard against unintentional disclosure of
confidential information and take special care not to store confidential
information where unauthorized personnel can see it, whether at work, at home,
in public places or elsewhere. Situations that could result in inadvertent
disclosure of such information include: discussing confidential information in
public (for example, in restaurants, elevators or airplanes); talking about
confidential information on mobile phones; working with sensitive information in
public using laptop computers; and transmitting confidential information via
fax. Within the workplace, do not assume that all Covered Persons should see
confidential information.

10.    PROTECTION AND PROPER USE OF COMPANY ASSETS AND PROPRIETARY INFORMATION

       Collectively, Covered Persons have a responsibility for safeguarding and
making proper and efficient use of the Company's property. Each of us also has
an obligation to prevent the Company's property from loss, damage, misuse,
theft, embezzlement or destruction. Theft, loss, misuse, carelessness and waste
of assets have a direct impact on the Company's profitability and may jeopardize
the future of the Company. Any situations or incidents that could lead to the
theft, loss, misuse or waste of Company property should be reported immediately
to the security department or to your supervisor or manager as soon as they come
to your attention.

       The Company depends on intellectual property, such as business and
marketing plans, databases, records, salary information and any unpublished
financial data and reports, for its continued vitality. If intellectual property
is not protected, it becomes available to other companies that have not made the
significant investment that the Company has made to produce this property and
thus gives away some of the Company's competitive advantage. All of the rules
stated above with respect to confidential information apply equally to
proprietary information.

11.    ILLEGAL PAYMENTS; RELATIONSHIPS WITH GOVERNMENT PERSONNEL

       Improper payments, whether illegal political contributions, bribery of
domestic or foreign officials, or similar acts, are contrary to the policy of
the Company, and funds and resources of the Company shall not be used directly
or indirectly for such purposes.

       The U.S. Foreign Corrupt Practices Act prohibits giving anything of
value, directly or indirectly, to officials of foreign governments or foreign
political candidates in order to obtain or retain business. It is strictly
prohibited to make illegal payments, including illegal political contributions,
of any kind to government officials or political candidates of any country.

       In addition, many jurisdictions have laws and regulations regarding
business gratuities which may be accepted by government personnel. For example,
business courtesies or entertainment such as paying for meals or drinks are
rarely appropriate when working with government officials. Gifts or courtesies
that would not be appropriate even for private parties are in all cases
inappropriate for government officials. Please consult the Company's Legal
Department for more guidance on these issues.

12.    WAIVERS OF THE CODE OF BUSINESS CONDUCT: APPLICABILITY

       Any waiver of this Code for executive officers or directors may be made
only by the Board of Directors or the Audit Committee, subject to any applicable
rules or regulations and the Company's Bye-laws.

       This Code does not require any changes to contractual arrangements in
effect on the date of its adoption. In addition, participation in investment
opportunities voluntarily offered by the Company shall not be a violation of
this Code provided that such investment is on the same terms as are negotiated
and accepted by unaffiliated third party investors participating in the
transaction.

13.    REPORTING OF ILLEGAL, IMPROPER OR OTHER QUESTIONABLE BEHAVIOR OR
       ACCOUNTING/AUDITING COMPLAINTS

       Covered Persons are expected to conduct themselves in a manner
appropriate for their work environment, and are also expected to be sensitive to
and respectful of the concerns, values and preferences of others. Whether an
employee, contractor, supplier or otherwise a member of the Company family,
Covered Persons are encouraged to promptly report any practices or actions they
believe to be inappropriate.

       This Code describes the procedures generally available for discussing and
addressing business conduct issues that arise. Speaking to the right people is
one of a Covered Person's first steps to understanding and resolving what are
often difficult questions. As a general matter, if a Covered Person has any
questions or concerns about compliance with this Code or is just unsure of what
the "right thing" is to do, the Covered Person is encouraged to speak with his
or her supervisor, manager or other appropriate persons within the Company. If a
Covered Person does not feel comfortable talking to any of these persons FOR ANY
REASON, the Covered Person should call someone in the Company's Legal
Department, the Company's Code of Business Conduct Compliance Officer, or report
the issues or concerns through the Company's anonymous web based or toll free
telephone reporting system. Each of these offices has been instructed to
register all complaints, brought anonymously or otherwise, and direct those
complaints to the appropriate channels within the Company.

       ACCOUNTING/AUDITING COMPLAINTS: The law also requires that the Company
have in place procedures for addressing complaints concerning auditing issues
and procedures for Covered Persons to anonymously submit their concerns
regarding accounting or auditing issues. Complaints concerning accounting or
auditing issues will be directed to the attention of the Company's Audit
Committee, or the appropriate members of that committee.

            Covered Persons may direct issues or complaints directly to the
Company's Code of Business Conduct Compliance Officer or indirectly through the
Company's confidential, anonymous web based or toll free telephone reporting
system.

                  Hanover, NH 03755

       Also, as discussed in the Introduction to this Code, Covered Persons
should know that if they report in good faith what they expect to be illegal or
improper activities, they should not be concerned about retaliation from others.
Any Covered Persons involved in retaliation will be subject to serious
disciplinary action by the Company. Furthermore, the Company could be subject to
criminal or civil actions for acts of retaliation against Covered Persons who
"blow the whistle" on U.S. securities law violations and other federal offenses.

14.    COOPERATION IN INTERNAL INVESTIGATIONS

       Covered Persons are expected to cooperate fully in all internal
investigations of any kind initiated by the (i) Board of Directors or any
Committee appointed by the Board, (ii) senior management, (iii) internal
auditors, (iv) external auditors, and (v) any regulatory or law enforcement
agency. Covered Persons are expected to respond to all inquiries with honesty
and integrity.

15.    CONFLICT WITH SUBSIDIARY COMPANY BUSINESS CODES OF CONDUCT AND CONFLICTS
       OF INTEREST POLICIES

       The Company recognizes that one or more of its operating subsidiaries
have codes of business conduct and conflicts of interest policies that have been
approved by their respective boards of directors. If any provision contained in
this Code conflicts with any provision contained in subsidiary company's code of
business conduct and conflict of interest policies, the provision in this Code
shall prevail. This Code may be approved for adoption by the board of directors
of any of the Company's subsidiaries.

      PRINCIPAL EXECUTIVE OFFICER CERTIFICATION PURSUANT TO RULE 13a-14(a)
                     OF THE SECURITIES EXCHANGE ACT OF 1934

I, Raymond Barrette, certify that:

I have reviewed this annual report of White Mountains Insurance Group, Ltd.;

Based on my knowledge, this report does not contain any untrue statement of a
material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not
misleading with respect to the period covered by this report;

Based on my knowledge, the financial statements, and other financial information
included in this report, fairly present in all material respects the financial
condition, results of operations and cash flows of the registrant as of, and
for, the periods presented in this report;

The registrant's other certifying officer and I are responsible for establishing
and maintaining disclosure controls and procedures (as defined in Exchange Act
Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as
defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and
have:

     (a) Designed such disclosure controls and procedures, or caused such
     disclosure controls and procedures to be designed under our supervision, to
     ensure that material information relating to the registrant, including its
     consolidated subsidiaries, is made known to us by others within those
     entities, particularly during the period in which this report is being
     prepared;

     (b) Designed such internal control over financial reporting, or caused such
     internal control over financial reporting to be designed under our
     supervision, to provide reasonable assurance regarding the reliability of
     financial reporting and the preparation of financial statements for
     external purposes in accordance with generally accepted accounting
     principles;

     (c) Evaluated the effectiveness of the registrant's disclosure controls and
     procedures and presented in this report our conclusions about the
     effectiveness of the disclosure controls and procedures, as of the end of
     the period covered by this report based on such evaluation; and

     (d) Disclosed in this report any change in the registrant's internal
     control over financial reporting that occurred during the registrant's most
     recent fiscal quarter (the registrant's fourth fiscal quarter in the case
     of an annual report) that has materially affected, or is reasonably likely
     to materially affect, the registrant's internal control over financial
     reporting; and

The registrant's other certifying officer and I have disclosed, based on our
most recent evaluation of internal control over financial reporting, to the
registrant's auditors and the audit committee of the registrant's board of
directors:

     (a) All significant deficiencies and material weaknesses in the design or
     operation of internal control over financial reporting which are reasonably
     likely to adversely affect the registrant's ability to record, process,
     summarize and report financial information; and

     (b) Any fraud, whether or not material, that involves management or other
     employees who have a significant role in the registrant's internal control
     over financial reporting.
