All forward-looking statements are based upon current plans, estimates and projections. Forward-looking statements rely on a number of assumptions concerning future events and are subject to a number of uncertainties and various risk factors, many of which are outside the Company's control, that could cause actual results to differ materially from such statements. See "Risk Factors" contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2008, as filed with the Securities and Exchange Commission. 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.

Important events and uncertainties that could cause the actual results, future dividends or future common share repurchases to differ include, but are not necessarily limited to: market conditions affecting our common share price; the possibility of severe or unanticipated losses from natural or man-made catastrophes; the effectiveness of our loss limitation methods; our dependence on principal employees; our ability to execute the business plan of our new insurance and reinsurance initiatives effectively, including the integration of those operations into our existing operations; increases in our general and administrative expenses due to new business ventures, which expenses may not be recoverable through additional profits; the cyclical nature of the reinsurance business; the levels of new and renewal business achieved; opportunities to increase writings in our core property and specialty reinsurance and insurance lines of business and in specific areas of the casualty reinsurance market; the sensitivity of our business to financial strength ratings established by independent rating agencies; the estimates reported by cedants and brokers on pro-rata contracts and certain excess of loss contracts where the deposit premium is not specified in the contract; the inherent uncertainties of establishing reserves for loss and loss adjustment expenses, particularly on longer-tail classes of business such as casualty; our reliance on industry loss estimates and those generated by modeling techniques; unanticipated adjustments to premium estimates; changes in the availability, cost or quality of reinsurance or retrocessional coverage; changes in general economic conditions; changes in governmental regulation or tax laws in the jurisdictions where we conduct business; our ability to assimilate effectively the additional regulatory issues created by our entry into new markets; the amount and timing of reinsurance recoverables and reimbursements we actually receive from our reinsurers; the overall level of competition, and the related demand and supply dynamics in our markets relating to growing capital levels in the reinsurance industry; declining demand due to increased retentions by cedants and other factors; the impact of terrorist activities on the economy; and rating agency policies and practices.
