NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

Note 1. Basis of Presentation

        These interim consolidated financial statements include the accounts of White Mountains Insurance Group, Ltd. (the "Company" or the "Registrant") and its subsidiaries (collectively, "White Mountains") and have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). The Company is a Bermuda exempted limited company with its headquarters located at the Bank of Butterfield Building, 42 Reid Street, 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 HM 11, Bermuda. White Mountains' reportable segments are OneBeacon, White Mountains Re, Esurance and Other Operations, as defined below.

        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) in 2001 (the "OneBeacon Acquisition").

        The White Mountains Re segment consists of White Mountains Re Group, Ltd. and its subsidiaries (collectively "White Mountains Re"). 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"), which has been a wholly-owned subsidiary of White Mountains since 2004. 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 underwriting advisory company specializing in international property and marine excess reinsurance.

        The Esurance segment consists of Esurance Holdings, Inc. and its subsidiaries (collectively, "Esurance"). Esurance, which has been a unit of White Mountains since 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"), all of which are in run-off. The Other Operations segment also includes White Mountains' investments in warrants to purchase common shares of both Montpelier Re Holdings, Ltd. ("Montpelier") and Symetra Financial Corporation ("Symetra").

        White Mountains completed numerous significant transactions during 2004 that affect 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.

        All significant intercompany transactions have been eliminated in consolidation. The financial statements include all adjustments considered necessary by management to fairly present the financial position, results of operations and cash flows of White Mountains. These interim financial statements may not be indicative of financial results for the full year and should be read in conjunction with the Company's 2004 Annual Report on Form 10-K. The preparation of financial statements in conformity

7



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. Refer to the Company's 2004 Annual Report on Form 10-K for a complete discussion regarding White Mountains' significant accounting policies.

Recent Accounting Pronouncements

        In December 2004, the Financial Accounting Standards Board ("FASB") issued Statement of Financial Accounting Standards ("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" ("SFAS 123") and supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25") 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.

        On April 14, 2005, the Securities and Exchange Commission (the "SEC") announced that the effective date of SFAS 123(R) will be suspended from June 15, 2005 until January 1, 2006, for calendar year companies. White Mountains currently expects to adopt SFAS 123(R) effective January 1, 2006 and does not expect the adoption to have a material effect on its financial condition, results of operations or cash flows. White Mountains already expenses the full cost of all its share-based compensation, including its outstanding options to acquire Common Shares.

Note 2. Acquisitions

Sirius

        On April 16, 2004, White Mountains acquired Sirius Insurance Holding Sweden AB and its subsidiaries ("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 included $10.5 million of expenses incurred in connection with the acquisition. The principal companies acquired were 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.

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

        The following table summarizes the loss and loss adjustment expense ("LAE") reserve activities of White Mountains' insurance and reinsurance subsidiaries for the three months ended March 31, 2005 and 2004:

        White Mountains did not experience any material net favorable or unfavorable development on prior accident year loss reserves during the first quarters of 2005 or 2004. During the first quarter of 2005, White Mountains Re recorded $6 million of unfavorable development on its workers compensation reserves relating to the Sierra Group acquisition, which was offset dollar-for-dollar by a reduction in the principal amount of the adjustable note that White Mountains Re obtained as part of the financing of that acquisition.

        In connection with purchase accounting for the acquisition of OneBeacon, 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. This net reduction to loss and LAE reserves of $300.0 million at June 1, 2001 ($75.9 million at March 31, 2005) is being recognized through an income statement charge ratably with and over the period the claims are settled. As such, White Mountains recognized $6.5 million of such charges, recorded as loss and LAE, for the three months ended March 31, 2005, and $10.1 million for the three months ended March 31, 2004.

        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 International's 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 $3.4 million of such charges for the three months ended March 31, 2005.

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 in the event that the reinsurer is unable to honor its obligations under reinsurance contracts.

OneBeacon

        At March 31, 2005, OneBeacon had $36.5 million of reinsurance recoverables on paid losses and $2,631.7 million (gross of $274.6 million in purchase accounting adjustments, as described in Note 3) that will become recoverable if claims are paid in accordance with current reserve estimates. Because reinsurance contracts do not relieve OneBeacon of its primary obligation to its policyholders, the collectibility of balances due from OneBeacon's reinsurers is critical to OneBeacon's financial strength. OneBeacon is selective with its reinsurers, placing reinsurance with only those reinsurers having strong financial condition. OneBeacon monitors the financial strength of its reinsurers on an ongoing basis. As a result, uncollectible amounts have not historically been significant. The following table provides a listing of OneBeacon's top reinsurers based upon recoverable amounts, the percentage of total reinsurance recoverables and the reinsurers' A.M. Best ratings.

Includes $389.7 million of Third Party Recoverables that NICO would pay under the terms of the NICO Cover if they are unable to collect from the Third Party Reinsurers.

        In connection with the OneBeacon Acquisition, Aviva caused OneBeacon to purchase two reinsurance contracts: a full risk-transfer cover from National Indemnity Company ("NICO") for up to $2.5 billion in old asbestos and environmental ("A&E") claims and certain other exposures (the "NICO Cover") and an adverse development cover from General Reinsurance Corporation ("GRC") for up to $400.0 million of adverse development on losses occurring in years 2000 and prior (the "GRC Cover") in addition to $170.0 million of reserves ceded as of the date of the OneBeacon Acquisition. The NICO Cover and GRC Cover, which were contingent on and occurred contemporaneously with the OneBeacon Acquisition, were put in place in lieu of a seller guarantee of loss and LAE reserves and are therefore accounted for as prospective reinsurance under GAAP in accordance with Emerging Issues Task Force Technical Matter Document No. D-54 ("EITF Topic D-54"). NICO and GRC are wholly-owned subsidiaries of Berkshire Hathaway Inc. ("Berkshire").

        Under the terms of the NICO Cover, NICO receives reinsurance recoverables from certain of OneBeacon's third party reinsurers ("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. Third Party Recoverables are typically for the amount of loss in excess of a stated level each year. White Mountains estimates that on an incurred basis, net of Third Party Recoverables, as of March 31, 2005 it has used approximately $1.7 billion of the coverage provided by NICO. At March 31, 2005, $14.6 million of the $1.7 billion of utilized coverage from NICO related to uncollectible Third Party Recoverables. Approximately $709.0 million of these incurred losses have been paid by NICO through March 31, 2005. To the extent that actual experience differs from White Mountains' estimate of ultimate A&E losses and Third Party Recoverables, future losses could utilize some or all of the protection remaining under the NICO Cover.

        Pursuant to the GRC Cover, OneBeacon is not entitled to recover losses to the full contract limit if such losses are reimbursed by GRC more quickly than anticipated at the time the contract was signed. OneBeacon will only seek reimbursement from GRC for claims which result in payment patterns similar to those supporting its recoverables recorded pursuant to the GRC Cover. The economic cost of not submitting certain other eligible claims to GRC is primarily the investment spread between the rate credited by GRC and the rate achieved by OneBeacon on its own investments. This cost, if any, is expected to be small.

White Mountains Re

        At March 31, 2005, White Mountains Re had $77.2 million of reinsurance recoverables on paid losses and $1,300.0 million that will become recoverable if claims are paid in accordance with current reserve estimates. Because reinsurance contracts do not relieve White Mountains Re of its obligation to its ceding companies, the collectibility of balances due from its reinsurers is critical to White Mountains Re's financial strength. White Mountains Re is selective with its reinsurers, placing reinsurance with only those reinsurers having strong financial condition. White Mountains Re monitors the financial strength of its reinsurers on an ongoing basis. Amounts due from certain of it reinsurers, including Olympus Reinsurance Company ("Olympus"), London Life & General Reinsurance Company Ltd. and London Life & Casualty Reinsurance Corp. ("London Life") and Imagine Re, are fully collateralized

Note 5. Investment Securities

        White Mountains' net investment income is comprised primarily of interest income associated with White Mountains' fixed maturity investments, dividend income from its equity investments and interest income from its short-term investments. Net investment income for the three months ended March 31, 2005 and 2004 consisted of the following:

  Less investment expenses     (3.6 )   (.9 )
   
 
 
Net investment income, pretax   $ 173.9   $ 71.0  
   
 
 

        During the first quarter of 2005, Montpelier declared a special dividend of $5.50 per share, payable to holders of both its common shares and warrants to acquire its common shares. White Mountains recorded pretax investment income of $74.1 million in the quarter for this special dividend, of which $34.7 million relating to its common share investment was included in net investment income from common equity securities and $39.4 million relating to its warrant investment was included in net investment income from other investments. In addition, White Mountains also recorded $4.9 million in pretax investment income from Montpelier's normal quarterly dividend during the first quarter of 2005.

        The composition of realized investment gains (losses) consisted of the following:

 
  Three Months Ended March 31,

Other investments     (14.9 )   (7.0 )
   
 
 
Net realized investment gains, before tax   $ 37.1   $ 61.8  
   
 
 

        In accordance with SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS 133"), White Mountains accounts for its Montpelier warrants at fair value as a component of other investments, and records changes in fair value through the income statement as realized investment gains or losses. White Mountains recorded investment losses of $20.4 million and investment gains of $3.8 million related to its Montpelier warrants for the three months ended March 31, 2005 and 2004, respectively.

        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 realized investment 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 Montpelier warrants have an exercise price of $16.67 per share (as adjusted for stock splits) and are exercisable until December 2011.

        The following table summarizes the carrying value of White Mountains' investment in Montpelier as of March 31, 2005 and December 31, 2004:

Impairment

        Temporary losses on investment securities are recorded as unrealized losses. Temporary losses do not impact net income and earnings per 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 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 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 March 31, 2005 (excluding short-term investments):

        For the three months ended March 31, 2005, White Mountains did not experience any material other-than-temporary impairment charges. White Mountains believes that the gross unrealized losses relating to its fixed maturity investments at March 31, 2005 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. White Mountains views these decreases in value as being temporary because it has the intent and ability to retain such investments until recovery. However, should White Mountains determine that it no longer has the intent and ability to hold a fixed maturity investment that has an existing unrealized loss resulting from an increase in market interest rates until it recovers, this loss would be realized through the income statement at the time such determination is made. White Mountains also believes that the gross unrealized losses recorded on its common equity securities and its other investments at March 31, 2005 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 March 31, 2005, White Mountains' investment portfolio did not include any investment securities with an after tax unrealized loss of more than $2.0 million.

    Total debt   $ 777.4   $ 783.3  
   
 
 

Senior Notes

        In 2003, Fund American Companies, Inc. ("Fund American"), a wholly-owned subsidiary of the Company, issued $700.0 million face value of senior unsecured debt through a public offering, at an issue price of 99.7% (the "Senior Notes"). The Senior Notes bear an annual interest rate of 5.9%, 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 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 resyndicated 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 Company's $300.0 million mandatorily redeemable preferred stock held by Berkshire (the "Berkshire Preferred Stock"). As of March 31, 2005, the Bank Facility was undrawn.

Sierra Note

        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 the first quarter of 2005, the Sierra Note was reduced by $6.0 million as a result of adverse development on the acquired reserves and run-off of unearned premium.

Atlantic Specialty Note

        In connection with its acquisition of Atlantic Specialty Insurance Company ("Atlantic Specialty"), a subsidiary of Atlantic Mutual Insurance Company ("Atlantic Mutual") on March 31, 2004, OneBeacon

15



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.

Note 7. Earnings Per Share

        Basic earnings per share amounts are based on the weighted average number of Common Shares outstanding excluding unearned restricted Common Shares which are being fully expensed over the vesting period and were anti-dilutive for all periods presented. Diluted earnings per share amounts are based on the weighted average number of Common Shares and the net effect of potentially dilutive Common Shares outstanding, based on the treasury stock method. The following table outlines the Company's computation of earnings per share for the three months ended March 31, 2005 and 2004:

The diluted earnings per share numerator for the three months ended March 31, 2005 has been adjusted to exclude $1.0 million of negative expense associated with outstanding options to acquire Common Shares (see note below). The diluted earnings per share numerator for the three months ended March 31, 2004 has been adjusted to exclude $.8 million of White Mountains' equity in earnings of unconsolidated affiliates, 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

The diluted earnings per share denominator for the three months ended March 31, 2005 includes the dilutive effects of options to acquire 45,630 Common Shares at an average strike price of $142.14 per Common Share. The diluted earnings per share denominator for the three months ended March 31, 2004 includes the dilutive effects of average outstanding warrants to acquire 1,724,200 Common Shares at an average strike price of $173.99 per Common Share. The warrants were fully exercised on June 29, 2004, therefore, this adjustment is not applicable for the 2005 period.

Note 9. Share-Based Compensation

        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 with an escalating exercise price 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 upon achievement of pre-defined business goals and the cost of these awards is expensed over the service period (typically three years), based on the market value of Common Shares. 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 all its share-based compensation, including its outstanding Options and Restricted Shares. White Mountains recorded compensation charges of $8.1 million and $59.4 million for outstanding performance shares during the three months ended March 31, 2005 and 2004.

        At December 31, 2004, OneBeacon expected to contribute $4.2 million to its pension plans and $6.9 million to its other postretirement plans during 2005. As of March 31, 2005, $1.0 million and $1.7 million were contributed to the pensions plans and other postretirement plans. OneBeacon anticipates contributing an additional $3.2 million and $5.2 million to the pension plans and other postretirement plans for the remainder of 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.

Item 2. 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 34). White Mountains believes these measures to be more relevant than comparable GAAP measures in evaluating White Mountains' financial performance and condition.


RESULTS OF OPERATIONS FOR THE THREE MONTHS ENDED MARCH 31, 2005 AND 2004

Overview

        White Mountains ended the first quarter of 2005 with a fully converted tangible book value per common and equivalent share of $348, up 13% over the last twelve months and up 2% since December 31, 2004, including dividends. Adjusted comprehensive net income for the quarter was $75 million compared to $194 million in the first quarter of the prior year. The decline was mainly due to $77 million of after-tax unrealized losses in the investment portfolio (which excludes $24 million of net unrealized losses from Symetra's fixed maturity portfolio), compared to after-tax unrealized gains of $99 million in the first quarter of 2004. Additionally, the dollar strengthened in the quarter, which resulted in $25 million of after-tax unrealized currency losses, and European storm Erwin caused $24 million of after tax losses, net of reinsurance. Net income rose 85% to $176 million driven by $74 million in pre-tax investment income ($56 million after tax) from a special dividend paid by Montpelier.

        White Mountains' total revenues increased by 20% in the first quarter of 2005 compared to 2004. Growth in revenues was driven by the 15% increase in earned premiums due to the Sirius Acquisition and OneBeacon's renewal rights agreement for Atlantic Mutual's segmented commercial insurance business, both of which took effect during the second quarter of 2004. Net investment income grew 144% in the first quarter of 2005 primarily due to a $74 million special dividend from Montpelier and from the income earned on the additional invested assets acquired in the Sirius Acquisition.

        White Mountains' total expenses grew 10% in the first quarter of 2005 as loss and LAE, insurance acquisition and underwriting expenses increased due to the Sirius Acquisition and Atlantic Mutual transactions. General and administrative costs were down 54% in the first quarter of 2005, primarily due to a decrease in incentive compensation accruals. White Mountains expenses the full cost of all its incentive compensation programs.

        The income tax provision related to pretax earnings for the first quarters of 2005 and 2004 represented effective tax rates of 25% and 40%, respectively. White Mountains' effective tax rate for

27



the first quarter of 2005 was lower than the U.S. statutory rate of 35% primarily due to income generated in jurisdictions other than the United States.

        White Mountains' net written premiums increased by 8% in the first quarter of 2005 compared to 2004, as a $216 million increase from the Sirius Acquisition was partially off set by a $135 million decrease reflecting the one-time assumption of unearned premiums from the Atlantic Mutual transaction in the first quarter of 2004.

I. Summary of Operations By Segment

        White Mountains conducts its operations through four segments: (i) OneBeacon, (ii) White Mountains Re, (iii) Esurance and (iv) Other Operations. 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 8 to the Consolidated Financial Statements.

Includes results from reciprocals (in the 2005 quarter) and run-off operations (in both periods). Results from reciprocals are net of business assumed by OneBeacon, which is reported in Personal Lines.

        OneBeacon's pretax income for the first quarter of 2005 was $160 million compared to $143 million for the first quarter of 2004 and its GAAP combined ratio was 95% for the 2005 period, compared to 96% for the 2004 period. Net written premiums for the first quarter of 2005 were $520 million, a decrease of 25% from 2004. The first three months of 2004 included $203 million in net written premiums related to renewal rights to the segmented commercial book of Atlantic Mutual, $135 million of which was non-recurring premium from the addition of unearned premiums transferred at closing.

        OneBeacon's total revenues for the first quarter of 2005 decreased by 8% compared to the first quarter of 2004, due principally to a decrease in earned premiums resulting from the impact of an agreement that OneBeacon entered into in late 2004 to sell the renewal rights to most of its New York commercial lines business (other than Atlantic Mutual business) to Tower Insurance Group. The first quarter of 2004 also included the remaining earned premium on business resulting from the renewal rights agreement with Liberty Mutual which expired in late 2003. Partially offsetting the decrease in total revenues, net investment income for the first quarter of 2005 increased 71% to $88 million compared to the first quarter of 2004, resulting primarily from a $35 million dividend from Montpelier in the 2005 period.

        OneBeacon's total expenses for the first quarter of 2005 decreased 12% compared to the first quarter of 2004, primarily due to lower incurred loss and loss adjustment expenses resulting from changes in the mix of business and re-underwriting efforts to shift away from unprofitable business to shorter-tail, segmented personal and commercial lines of business. The decrease in total expenses from 2004 was partially offset by an $8 million release in the first quarter of 2004 of the New York assigned risk liability due to the shrinking of the New York assigned risk pool.

        Other revenue and general and administrative expenses for the three months ended March 31, 2005 decreased significantly compared to the first quarter of 2004, mainly due to a decrease in revenues and related expenses of two 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.

        Specialty Lines.    The specialty lines combined ratio for the first quarter of 2005 was 83%, compared to 78% in the first quarter of 2004. The current period ratio was higher primarily due to approximately $13 million in favorable prior accident year development, primarily at AutoOne Insurance, in the first quarter of 2004, compared to approximately $4 million of favorable prior accident year development in the first quarter of 2005 at agricultural, International Marine Underwriters and National Farmers Union Property and Casualty Company. Written premiums for specialty lines were consistent for the three month period ended March 31, 2005 compared to the same period in the prior year.

        Personal Lines.    The combined ratio for personal lines for the first quarter of 2005 was 95%, a 2 point improvement from 97% in the first quarter of 2004, mainly due to an improved loss ratio

29



resulting from favorable catastrophe and large loss activity compared to the same period in the prior year. Premiums in this line decreased 3% in the first quarter of 2005 to $155 million, compared to $160 million in the prior year period, mainly due to a shortfall in new business production in the northeast region. During the first quarter of 2005, personal lines written premiums included $7 million assumed from New Jersey Skylands Insurance Association through a quota-share reinsurance agreement.

        Commercial Lines.    The combined ratio for commercial lines was 100% for the first quarter of 2005, consistent with a 101% combined ratio in the first quarter of 2004. Written premiums for commercial lines decreased 57% for the first quarter of 2005 when compared to the same period in the prior year reflecting the one-time assumption of Atlantic Mutual premiums in the first quarter of 2004. The continued change in our mix of business to shorter-tail business along with the sale of our non-Atlantic Mutual, New York commercial lines business has contributed to a 5 point improvement in the loss ratio for the first quarter of 2005. This is offset, however by an increased expense ratio due to the lower premium base.

White Mountains Re

        Financial results and GAAP combined ratios for White Mountains Re for the three months ended March 31, 2005 and 2004 follows:

        White Mountains Re recorded a GAAP combined ratio of 99% and pre-tax income of $55 million for the first quarter of 2005, compared to 93% and $48 million for the first quarter of 2004. During the first quarter of 2005, White Mountains Re recorded approximately $33 million in pretax losses, net of reinsurance (contributing approximately 9 points to the combined ratio), attributable to European storm Erwin, which affected northern Europe, particularly Scandinavia where Sirius International is a major reinsurer. There was no significant property catastrophe activity in the first quarter last year. Earnings from business segments not impacted by European storm Erwin have partially offset the impact of this first quarter catastrophe. Total revenues and total expenses were both up substantially in the first quarter of 2005 compared to the same period in 2004 due to the Sirius Acquisition.

30



        White Mountains Re's gross written premiums increased by $256 million, or 71% from the first quarter of 2004 to 2005 and net written premiums increased $216 million, which is greater than a 100% increase over the comparable prior period. The increase is due mainly to the acquisition of Sirius, which closed in the second quarter of 2004. For the first quarter of 2005, Sirius contributed $292 million of gross premiums written and $216 million of net premiums written, respectively. Partially offsetting the increases resulting from this acquisition was the non-renewal of several large treaties at Folksamerica whose pricing or other terms did not meet White Mountains Re's underwriting guidelines.

        White Mountains Re receives fee income on reinsurance placements referred to Olympus and is entitled to a profit commission on net underwriting profits on referred business. The additional capacity provided by the quota share relationship with Olympus supports White Mountains Re's ability to offer significant reinsurance capacity to ceding companies. White Mountains Re recognized net fee income of $19 million from Olympus in the first quarter of 2005 as compared to $17 million for the comparable period in the prior year. The increase in fee income is due primarily to Sirius International's quota share reinsurance with Olympus, which began in the second quarter of 2004.

        In April 2005, Sirius received a notice of hearing from the Office of Insurance Regulation of the State of Florida concerning an allegation that Sirius sold insurance policies in the state without proper licensing. Sirius does not believe that it has engaged in improper conduct and will cooperate with the Office's inquiries.

Esurance

        Esurance's financial results and GAAP combined ratios for the three months ended March 31, 2005 and 2004 follows:

        Esurance achieved pretax income of $2 million in the first quarter of 2005, compared to break-even results in the first quarter of the prior year. Net written premiums for the first quarter of 2005 were $78 million, an increase of 73% from $45 million in the first quarter of 2004. As of March 31, 2005, Esurance's in-force policy count was 143,992 policies, a 70% increase over March 31, 2004. Significant growth in premium volume and policies resulted from Esurance's expansion of its

31



offline marketing efforts, including radio, television, and direct mail, complementing its existing online marketing and online agency channels.

        Esurance's combined ratio of 104% for the three months ended March 31, 2005 was consistent with the prior year quarter. Esurance's loss ratio improved from 74% to 68%. This improvement was driven by favorable results from Esurance's proprietary auto insurance program and solid claims performance from its in-house claims operation, as well as 3 points of favorable development on loss reserves. Esurance's expense ratio increased from 30% to 36%, due to a significant increase in advertising spending to take advantage of current growth opportunities in the online auto insurance market.

Other Operations

        Other Operations consists of the operations of the Company and the Company's intermediate subsidiary holding companies and the International American Group, as well as White Mountains' investments in Montpelier and Symetra warrants. A summary of White Mountains' financial results from its Other Operations segment for the three months ended March 31, 2005 and 2004 follows:

        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.

        White Mountains' Other Operations segment reported pre-tax income of $7 million for the first quarter of 2005, compared to a pre-tax loss of $77 million for the first quarter of 2004. The improvement was principally due to: (i) the aforementioned special dividend from Montpelier in the 2005 quarter, $39 million of which was reported in this segment; (ii) a $14 million realized loss recorded in the 2004 quarter from the impact currency fluctuations had on hedging the cost of funding for the Sirius acquisition; (iii) a $14 million gain recorded in other revenues in the 2005 quarter from the settlement of a lawsuit in which White Mountains was a plaintiff; and (iv) a lower accrual for incentive compensation in the first quarter of 2005, compared to the 2004 quarter.

II. Summary of Investment Results

Investment Philosophy

        White Mountains manages substantially 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 March 31, 2005 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

        The GAAP total return on invested assets for the first quarter of 2005 was 0.4%. Net investment income more than doubled to $174 million, reflecting the impact of the Montpelier special dividend and additional investment assets acquired in the Sirius transaction. The increase in the general level of interest rates experienced during the first quarter, which caused the prices of bonds to fall, held down White Mountains' overall investment results. However, White Mountains' equity portfolio outperformed the Standard & Poor's 500 Index and the duration and creditworthiness of its fixed income portfolio helped to mitigate the effects of rising interest rates.

Montpelier investment

        The following table details the book value effect of White Mountains' total investment in Montpelier for the three months ended March 31, 2005 and 2004:

 
  Three Months Ended March 31,
 
 
  2005
  2004
 
 
  Millions

 
Net investment income, pretax   $ 79.0   $ 4.3  
Net realized investment gains (losses), pretax     (20.4 )   39.0  
   
 
 
Total revenues, pretax     58.6     43.3  
Taxes on net investment income and net realized investment gains (losses)     (16.1 )   (12.8 )
   
 
 
Total revenues, after tax     42.5     30.5  
Change in net unrealized investment gains, after tax     (13.1 )   31.7  
Equity in earnings of Montpelier, after tax         11.0  
   
 
 
Net after tax change in book value from Montpelier investment   $ 29.4   $ 73.2  
   
 
 

        During the first quarter of 2005, Montpelier declared a special dividend of $5.50 per share, payable to holders of both its common shares and warrants to acquire its common shares. White Mountains recorded pretax dividend income of $74.1 million in the quarter for this special dividend, in addition to $4.9 million in dividend income from Montpelier's normal quarterly dividend. The special

33



dividend resulted in a decrease in Montpelier's stock price, which reduced the value of White Mountains' investment in Montpelier's common shares and warrants. As a result, White Mountains recorded investment losses of $20.4 million related to its Montpelier warrants and a $13.1 million decrease in after tax unrealized gains related to its common share investment for the three months ended March 31, 2005.

        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, and changed the method of accounting for its remaining Montpelier common stock to the fair value method, resulting in a $32.5 million increase in after tax unrealized gains.

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 27.

        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 26.


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 Common Shares and on mandatorily redeemable preferred stock, 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

34



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.

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:

        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 the first quarter of 2005, OneBeacon paid a dividend of $230 million to Fund American.

White Mountains Re:

        Based on December 31, 2004 statutory surplus of $917 million, Folksamerica Re 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 Re 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.

        During the first quarter of 2005, Folksamerica Re paid $8 million of cash dividends to its immediate parent. Sirius International has the ability to pay dividends subject to the availability of unrestricted statutory surplus. Historically, Sirius International had allocated the majority of its earnings to the Safety Reserve (see Safety Reserve below). Currently, Sirius International has no unrestricted statutory surplus.

35



        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 the first quarter of 2005, WMU paid $15 million of cash dividends to its immediate parent.

        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.

        During the first quarter of 2005, White Mountains Re distributed $83 million of cash and investments from various holding companies to its immediate parent.

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, an amount equal to Sirius International's safety reserve of $1.0 billion at March 31, 2005, net of the related deferred tax liability established at the Swedish tax rate of 28%, is classified as equity under GAAP and as restricted surplus under local statutory requirements. 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.

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.

36



        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 March 31, 2005 and December 31, 2004:

        White Mountains has historically obtained its float primarily through acquisitions, as opposed to organic growth. In recent years, 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 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. The decrease in White Mountains' insurance float position from December 31, 2004 to March 31, 2005 was principally due to the continued run-off of OneBeacon's reserves, as described below, and incentive compensation payments made during the quarter.

        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 exposures and premium as those written in the past.

37



        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 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.

        Fund American's Senior Notes are currently rated "Baa2" (Adequate, the 9th highest of 21 ratings) with a stable outlook by Moody's Investor Services and "BBB-" (Adequate, the 10th highest of 24 ratings) with a positive outlook by Standard & Poor's 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 March 31, 2005, 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.

38



        Fund American has a $400 million revolving credit facility (the "Bank Facility"), under which both Fund American and the Company are permitted borrowers. As of March 31, 2005, the Bank Facility, which matures in August 2009, was undrawn. 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. 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 March 31, 2005, 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.
