All statements, other than statements of historical facts, included or referenced in this release which address activities, events or developments which we 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.

• future capital expenditures.

These statements are based on certain assumptions and analyses made by OneBeacon 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 to our expectations and predictions is subject to a number of risks and uncertainties that could cause actual results to differ materially from expectations, including:

• claims arising from catastrophic events, such as hurricanes, windstorms, earthquakes, floods, or terrorist attacks;
• recorded loss and loss adjustment expense reserves subsequently proving to have been inadequate;
• the continued availability and cost of reinsurance coverage;
• 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 agents;
• changes in domestic or foreign laws or regulations, or their interpretation, applicable to OneBeacon, its competitors, its agents or its customers;
• an economic downturn or other economic conditions adversely affecting its financial position including stock market volatility;
• actions taken by ratings agencies from time to time, such as financial strength or credit ratings downgrades or placing ratings on negative watch;
• the risks that are described from time to time in OneBeacon's filings with the Securities and Exchange Commission, including but not limited to OneBeacon's Annual Report on the Form 10-K for the fiscal year ended December 31, 2011 filed February 28, 2012 and OneBeacon's Quarterly Report on the Form 10-Q for the fiscal quarter ended September 30, 2012 filed October 30, 2012.

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 OneBeacon will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, OneBeacon or its business or operations. OneBeacon assumes no obligation to update publicly any such forward-looking statements, whether as a result of new information, future events or otherwise.
