Definitions and presentation:
All financial information contained herein is unaudited except for the information for the fiscal year ended December 31, 2010.  Amounts may not reconcile exactly due to rounding differences.
 
In presenting the Company's results, management has included certain schedules containing financial measures that are not calculated under standards or rules that comprise accounting principles generally accepted in the United States (GAAP). Such measures, including segment underwriting income or loss (pages 14-18), operating income or loss (page 7), related underwriting ratios (pages 14-18), book value per common share and fully converted book value per common share (page 11), are referred to as non-GAAP measures. These non-GAAP measures may be defined or calculated differently by other companies.  Management believes these measures, which are used to monitor the results of operations, allow for a more complete understanding of the underlying business.  These measures should not be viewed as a substitute for those determined in accordance with GAAP.  Reconciliations of such measures to the most comparable GAAP figures are included within this financial supplement in accordance with Regulation G.

Safe Harbor Statement Regarding Forward-Looking Statements:
This financial supplement contains 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.  Forward-looking statements are based on our current plans or expectations that are inherently subject to significant business, economic and competitive uncertainties and contingencies.  These uncertainties and contingencies can affect actual results and could cause actual results to differ materially from those expressed in any forward-looking statements made by, or on behalf of, us.  In particular, statements using words such as “may,” “should,” “estimate,” “expect,” “anticipate,” “intend,” “believe,” “predict,” “potential,” or words of similar import generally involve forward-looking statements.  The inclusion of forward-looking statements in this financial supplement should not be considered as a representation by us or any other person that our current plans or expectations will be achieved.  Numerous factors could cause our actual results to differ materially from those in forward-looking statements, including, but not limited to, the occurrence of severe natural or man-made catastrophic events; the effectiveness of our loss limitation methods and pricing models; the adequacy of our ceding companies’ ability to assess the risks they underwrite; the adequacy of our liability for unpaid losses and loss adjustment expenses; the effects of emerging claim and coverage issues on our business; our ability to maintain our A.M. Best and S&P ratings; our ability to raise capital on acceptable terms if necessary; our exposure to credit loss from counterparties in the normal course of business; our ability to provide reinsurance from Bermuda to insurers domiciled in the United States; the effect on our business of the cyclicality of the property and casualty reinsurance business; the effect on our business of the highly competitive nature of the property and casualty reinsurance industry; losses that we could face from terrorism, political unrest and war; our dependence on the business provided to us by reinsurance brokers and our exposure to credit risk associated with our brokers during the premium and loss settlement process; the availability of catastrophic loss protection on acceptable terms; foreign currency exchange rate fluctuation; our ability to maintain and enhance effective operating procedures and internal controls over financial reporting; our need to make many estimates and judgments in the preparation of our financial statements; the limitations placed on our financial and operational flexibility by the representations, warranties and covenants in our debt and credit facilities; our ability to retain key executives and attract and retain additional qualified personnel in the future; the performance of our investment portfolio; fluctuations in the mortgage-backed and asset-backed securities markets; the effects of changes in market interest rates on our investment portfolio; the concentration of our investment portfolio in any particular industry, asset class or geographic region; the effects that the imposition of U.S. corporate income tax would have on Platinum Underwriters Holdings, Ltd. and its non-U.S. subsidiaries; the risk that U.S. persons who hold our shares will be subject to adverse U.S. federal income tax consequences under certain circumstances; the risk that U.S. persons who dispose of our shares may be subject to U.S. federal income taxation at the rates applicable to dividends on all or a portion of their gains, if any; the risk that holders of 10% or more of our shares may be subject to U.S. income taxation under the “controlled foreign corporation” rules; the effect of changes in U.S. federal income tax law on an investment in our shares; the possibility that we may become subject to taxes in Bermuda; the effect on our business of potential changes in the regulatory system under which we operate; the impact of regulatory regimes and changes to accounting rules on our financial results, irrespective of business operations; the uncertain impact on our business of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010; the dependence of the cash flows of Platinum Underwriters Holdings, Ltd., a holding company, on dividends, interest and other permissible payments from its subsidiaries to meet its obligations; the risk that our shareholders may have greater difficulty in protecting their interests than would shareholders of a U.S. corporation; and limitations on the ownership, transfer and voting rights of our common shares.  As a consequence, our future financial condition and results may differ from those expressed in any forward-looking statements made by, or on behalf of, us.  The foregoing factors should not be construed as exhaustive.  Additionally, forward-looking statements speak only as of the date they are made, and we undertake no obligation to revise or update forward-looking statements to reflect new information or circumstances after the date hereof or to reflect the occurrence of future events.

The Company has developed the estimates of losses expected from certain catastrophes for its portfolio of property, marine, workers’ compensation, personal accident contracts and catastrophe contributions from insurance-linked securities using commercially available catastrophe models, which are applied and adjusted by the Company.  These estimates include assumptions regarding the location, size and magnitude of an event, the frequency of events, the construction type and damageability of property in a zone, and the cost of rebuilding property in a zone, among other assumptions.  These estimates do not include any losses that may be expected to arise from the Company’s casualty portfolio as a result of such catastrophes.  Return period refers to the frequency with which losses of a given amount or greater are expected to occur.

Gross loss estimates are net of reinstatement premiums but before income tax.  Net loss estimates are net of reinstatement premiums and net of retrocessional recoveries but before income tax.

The estimates set forth above are based on assumptions that are inherently subject to significant uncertainties and contingencies.  These uncertainties and contingencies can affect actual losses and could cause actual losses to differ materially from those expressed above.  In particular, modeled loss estimates do not necessarily accurately predict actual losses, and may significantly misestimate actual losses.  Such estimates, therefore, should not be considered as a representation of actual losses.  Investors should not rely on the foregoing information when considering investment in the Company.  The Company undertakes no duty to update or revise such information to reflect the occurrence of future events.
