[Letterhead] Exhibit 99(a) [WHITE MOUNTAINS LOGO] CONTACT: DENNIS BEAULIEU (802) 295-4510 WHITE MOUNTAINS REPORTS 2001 RESULTS HAMILTON, Bermuda, February 20, 2002 - White Mountains Insurance Group, Ltd. ended 2001 with a fully converted tangible book value per share of $226 (which includes net deferred credits), an increase of $38, or 21% (including dividends), from December 31, 2000. The increase resulted primarily from White Mountains' June 1, 2001 bargain purchase of OneBeacon Insurance Group, offset by operating losses at both OneBeacon and Folksamerica. Chairman Jack Byrne said, "2001 was an eventful year for us. After completing the OneBeacon acquisition on June 1st, we moved quickly to fix the balance sheet, restructure the investment portfolio and improve underwriting results. On November 1st, we completed the Liberty book transfer to clearly focus on making OneBeacon a profitable company in the Northeast and selected specialty markets. Having emerged from September 11th in good health, we invested large amounts of capital in the reinsurance business through a capital contribution to Folksamerica and an equity investment in Montpelier Re. I believe that we are well positioned to see some significant improvements in our operating results in all areas. We WILL have a fine company here." White Mountains reported a comprehensive net loss of $302 million or $45 per share for the year ended December 31, 2001 (includes previously reported $85 million loss stemming from the events of September 11th), compared to comprehensive net income of $448 million or $76 per share for the comparable 2000 period. The comprehensive loss results from a $207 million comprehensive net loss at OneBeacon, a $48 million comprehensive net loss at Folksamerica and approximately $79 million in financing charges and accretion of purchase accounting adjustments related to the acquisition of OneBeacon. The comprehensive net loss for 2001 also includes approximately $89 million of income from net deferred credit amortization and a non-recurring charge of $59 million for share appreciation expense relating to the financing of OneBeacon that have no effect on tangible book value per share. Comprehensive net income for the year ended December 31, 2000 includes a $280 million after tax gain related to the sale of a subsidiary containing the Company's holdings in Financial Security Assurance and a $95 million gain related to the taxation of the sale of Fireman's Fund Insurance Company in 1991. RESULTS OF SIGNIFICANT OPERATING SUBSIDIARIES ONEBEACON. OneBeacon reported a $207 million comprehensive net loss for the seven months ended December 31, 2001, which included $276 million in after tax losses from operations and $69 million of after tax net investment gains. OneBeacon's combined ratio for the year ended December 31, 2001, excluding non-recurring transactions related to the acquisition, was 121% (including 1 point to strengthen prior year reserves recorded in the fourth quarter) on earned premiums of $3.9 billion. The accident year combined ratio for ongoing operations was 109% excluding approximately 5 points for losses incurred on September 11th. Business transferred to Liberty and other business in run-off had 122% and 167% accident year combined ratios, respectively. As previously reported, OneBeacon will quota share reinsure 67% and 33% of the renewal business written by Liberty Mutual over the first and second consecutive twelve month periods, respectively. (more)

Ray Barrette, Chairman and CEO of OneBeacon, said, "Our reported results do not yet reflect the effects of significant underwriting and claims actions taken since the acquisition of OneBeacon. The ongoing commercial lines business had an accident year combined ratio of 109% excluding 12 points for September 11th claims. We have taken multiple re-underwriting actions and pricing is up 16% for the year and 25% for January 2002. Our ongoing personal lines business had an accident year combined ratio of 110%. Pricing on this business is up 16%, which includes our aggressive rate pursuit, insurance-to-value programs and other underwriting actions. Our ongoing specialty businesses had a 99% combined ratio and are also getting meaningful price increases. We are investing in our claims organization in order to achieve better claims results. We have added staff, aligned authorities and accountabilities to the Chief Claims Officer and reviewed all significant claims to ensure proper handling and reserving. With runoff businesses declining rapidly, we should see the impact of those activities in our results as 2002 progresses." FOLKSAMERICA. Folksamerica reported a $48 million comprehensive net loss during 2001 versus $24 million of comprehensive net income for the comparable 2000 period. Folksamerica's 2001 comprehensive net loss consisted of $28 million in losses from its reinsurance operations and $23 million in losses from other insurance operations, offset by $3 million in net investment gains. The loss from other insurance operations consists primarily of Esurance's after-tax operating losses ($16 million) during its development stage. Folksamerica's 2001 combined ratio, adjusted for the effects of retroactive reinsurance and the economic value of transactions at the holding company level, was 113% compared to 116% for the year 2000. The pre-tax cost of the September 11th events was $25 million and a pre-tax reserve of $5 million was established for Enron exposures in 2001. Ray Barrette commented, "These results, disappointing in absolute terms but much better than those reported by most competitors, demonstrate Folksamerica's superior risk management and conservative reserving practices." Steve Fass, CEO of Folksamerica, said, "The $400 million capital contribution received from OneBeacon demonstrated White Mountains' commitment to our business. This allowed us to participate fully in the 1/1/2002 renewal season. The potential for the remainder of 2002 remains good, helped by the significant capacity we are managing. Folksamerica also will have the opportunity to further benefit from the hardened property catastrophe reinsurance market through its quota share reinsurance agreement with newly formed Olympus Re." OTHER ACTIVITIES On December 14, 2001, White Mountains announced that it played a lead role with the Benfield Group in establishing a new Bermuda-domiciled reinsurance company, Montpelier Reinsurance Ltd., to respond to the current favorable underwriting and pricing environment in the reinsurance industry. Montpelier, with more than $1.0 billion in fresh capital, is focused on writing property per risk and catastrophe excess of loss reinsurance, facultative reinsurance, whole account quota share reinsurance and property retrocession reinsurance. White Mountains and its subsidiaries have an approximately 25% economic ownership interest in Montpelier. Tony Taylor, CEO and Chief Underwriting Officer, leads the company. On December 20, 2001, White Mountains, through its newly formed subsidiary Fund American Re, completed its acquisition of substantially all of the international reinsurance operations of the Folksam Group of Stockholm, Sweden. Fund American Re is a commercially domiciled Bermuda insurer, which maintains its executive office and an operating branch in Stockholm, Sweden, and also operates through a branch office in Singapore. The net assets of Folksam acquired by Fund American Re were valued at approximately $67 million on the date of purchase. The purchase price consisted of approximately $34 million in cash and notes and 86,385 common shares of White Mountains (approximately $30 million). (more)

Tom Kemp, President of White Mountains commented, "We have put in place a comprehensive structure to enhance our ability to leverage our international presence. We are delighted with all the talent we have in place to manage our growing reinsurance businesses."
