The information contained in this press release may contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. All statements, other than statements of historical facts, included or referenced in this press release which address activities, events or developments which White Mountains expects or anticipates will or may occur in the future are forward-looking statements. The words "will", "believe," "intend," "expect," "anticipate," "project," "estimate," "predict" and similar expressions are also intended to identify forward-looking statements. These forward-looking statements include, among others, statements with respect to White Mountains:


    --  changes in adjusted book value per share or return on equity;
    --  business strategy;
    --  financial and operating targets or plans;
    --  incurred losses and the adequacy of its loss and LAE reserves and
        related reinsurance;
    --  projections of revenues, income (or loss), earnings (or loss) per share,
        dividends, market share or other financial forecasts;
    --  expansion and growth of its business and operations; and
    --  future capital expenditures.

These statements are based on certain assumptions and analyses made by White Mountains in light of its experience and perception of historical trends, current conditions and expected future developments, as well as other factors believed to be appropriate in the circumstances. However, whether actual results and developments will conform with its expectations and predictions is subject to a number of risks and uncertainties that could cause actual results to differ materially from expectations, including:


    --  the risks associated with Item 1A of White Mountains' 2012 Annual Report
        on Form 10-K;
    --  claims arising from catastrophic events, such as hurricanes,
        earthquakes, floods or terrorist attacks;
    --  the continued availability of capital and financing;
    --  general economic, market or business conditions;
    --  business opportunities (or lack thereof) that may be presented to it and
        pursued;
    --  competitive forces, including the conduct of other property and casualty
        insurers and reinsurers;
    --  changes in domestic or foreign laws or regulations, or their
        interpretation, applicable to White Mountains, its competitors or its
        clients;
    --  an economic downturn or other economic conditions adversely affecting
        its financial position;
    --  recorded loss reserves subsequently proving to have been inadequate;
    --  actions taken by ratings agencies from time to time, such as financial
        strength or credit ratings downgrades or placing ratings on negative
        watch; and
    --  other factors, most of which are beyond White Mountains' control.

Consequently, all of the forward-looking statements made in this press release are qualified by these cautionary statements, and there can be no assurance that the actual results or developments anticipated by White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, White Mountains or its business or operations. White Mountains assumes no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
