In addition to the GAAP financial measures set forth in this Financial Supplement, the Company has included certain non-GAAP financial measures within the meaning of Regulation G. The Company has consistently provided these financial measures in previous investor communications and the Company's management believes that these measures are important to investors and other interested persons, and that investors and such other persons benefit from having a consistent basis for comparison between quarters and for comparison with other companies within the industry. These measures may not, however, be comparable to similarly titled measures used by companies outside of the insurance industry. Investors are cautioned not to place undue reliance on these non-GAAP measures in assessing the Company's overall financial performance.

The Company uses “operating (loss) income (attributable) available to RenaissanceRe common shareholders” as a measure to evaluate the underlying fundamentals of its operations and believes it to be a useful measure of its corporate performance. “Operating (loss) income (attributable) available to RenaissanceRe common shareholders” as used herein differs from “net (loss) income (attributable) available to RenaissanceRe common shareholders,” which the Company believes is the most directly comparable GAAP measure, by the exclusion of net realized and unrealized gains and losses on investments, excluding other investments - catastrophe bonds, net foreign exchange gains and losses, corporate expenses associated with the acquisition of TMR and the subsequent sale of RenaissanceRe UK, the income tax expense or benefit associated with these adjustments and the portion of these adjustments attributable to the Company's redeemable noncontrolling interests." The Company's management believes that “operating (loss) income (attributable) available to RenaissanceRe common shareholders” is useful to investors because it more accurately measures and predicts the Company's results of operations by removing the variability arising from: fluctuations in the fair value of the Company's fixed maturity investment portfolio, equity investments trading, other investments (excluding catastrophe bonds) and investments-related derivatives; fluctuations in foreign exchange rates; corporate expenses associated with the acquisition of TMR and the subsequent sale of RenaissanceRe UK; the associated income tax expense or benefit of these adjustments; and the portion of these adjustments attributable to the Company's redeemable noncontrolling interests. The Company also uses “operating (loss) income (attributable) available to RenaissanceRe common shareholders” to calculate “operating (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted” and “operating return on average common equity - annualized.” The following table is a reconciliation of: (1) net (loss) income (attributable) available to RenaissanceRe common shareholders to "operating (loss) income (attributable) available to RenaissanceRe common shareholders"; (2) net (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted to "operating (loss) income (attributable) available to RenaissanceRe common shareholders per common share - diluted"; and (3) return on average common equity - annualized to "operating return on average common equity - annualized." Comparative information for all prior periods has been updated to conform to the current methodology and presentation.

The Company has included in this Financial Supplement “tangible book value per common share” and “tangible book value per common share plus accumulated dividends.” “Tangible book value per common share” is defined as book value per common share excluding goodwill and intangible assets per share. “Tangible book value per common share plus accumulated dividends” is defined as book value per common share excluding goodwill and intangible assets per share, plus accumulated dividends. The Company's management believes “tangible book value per common share” and “tangible book value per common share plus accumulated dividends” are useful to investors because they provide a more accurate measure of the realizable value of shareholder returns, excluding the impact of goodwill and intangible assets. The following table is a reconciliation of book value per common share to "tangible book value per common share'" and "tangible book value per common share plus accumulated dividends."

The Company has included in this Financial Supplement “retained total investment result.” “Retained total investment result" is defined as consolidated total investment result less the portion attributable to redeemable noncontrolling interests, certain third-party vehicles and joint ventures. “Retained total investment result” differs from consolidated total investment result, which the Company believes is the most directly comparable GAAP measure, due to the exclusion of the investment result attributable to redeemable noncontrolling interests, certain third-party vehicles and joint ventures. The Company's management believes “retained total investment result” is useful to investors and other interested parties because it provides a measure of the portion of the Company's investment result, that impacts the investment result included in net (loss) income (attributable) available to RenaissanceRe common shareholders. The following table is a reconciliation of consolidated total investment result to “retained total investment result.”
