HAMILTON, Bermuda, April 21, 2011 /PRNewswire/ -- OneBeacon Insurance Group, Ltd.

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 release which address activities, events or developments which OBH or White Mountains expect or anticipate 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 OBH's and/or White Mountains':

• change in book value per share or adjusted book value per share or return on equity;
• business strategy;
• financial and operating targets or plans;
• incurred loss and loss adjustment expenses and the adequacy of OBH's and/or White Mountains' loss and loss adjustment expense 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 OBH's and/or White Mountains' business and operations; and
• future capital expenditures.

These statements are based on certain assumptions and analyses made by OBH and/or White Mountains in light of their 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 OBH's and/or White Mountains' 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 discussed beginning on page 18 of OBH's Annual Report on Form 10-K for the year ended December 31, 2010, filed March 16, 2011;
• the risks discussed beginning on page 32 of White Mountains' Annual Report on Form 10-K for the year ended December 31, 2010, filed February 28, 2011;
• recorded loss and loss adjustment expense reserves subsequently proving to have been inadequate;
• claims arising from catastrophic events, such as hurricanes, windstorms, earthquakes, floods or terrorist attacks;
• the continued availability and cost of reinsurance;
• competitive forces, including the conduct of other property and casualty insurers and reinsurers and agents;
• changes in domestic or foreign laws or regulations, or their interpretation, applicable to OBH and/or White Mountains, OBH's and/or White Mountains' competitors, OBH's and/or White Mountains' agents or OBH's and/or White Mountains' customers;
• the continued availability of capital and financing;
• general economic, market or business conditions;
• an economic downturn or other economic conditions adversely affecting OBH's and/or White Mountains' financial position;
• business opportunities (or lack thereof) that may be presented to OBH and/or White Mountains and pursued;
• actions taken by rating agencies from time to time, such as financial strength or credit rating downgrades or placing ratings on negative watch; and
• other factors, most of which are beyond OBH's and/or 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 OBH and/or White Mountains will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, OBH's and/or White Mountains' business or operations. OBH and White Mountains assume no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
