Questions and Answers 84

Appendix Reconciliation of Non-GAAP Financial Measures 85

Appendix RECONCILIATION OF NON-GAAP FINANCIAL MEASURES Non-GAAP Financial Measures We analyze our performance using non-GAAP financial measures which exclude or include amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We believe the following non-GAAP financial measures are better performance measures and better indicators of the revenue and profitability and underlying trends in our business: • After-tax adjusted operating income or loss, which excludes realized investment gains or losses and certain other items, as applicable; • Adjusted operating return on equity, which is calculated using after-tax adjusted operating income or loss and excludes from equity the unrealized gain or loss on securities and net gain on hedges; and • Book value per common share, which is calculated excluding accumulated other comprehensive income (AOCI). Realized investment gains or losses and unrealized gains or losses on securities and net gains on hedges depend on market conditions and do not necessarily relate to decisions regarding the underlying business of our Company. Book value per common share excluding certain components of AOCI, certain of which tend to fluctuate depending on market conditions and general economic trends, is an important measure. We also exclude certain other items from our discussion of financial ratios and metrics in order to enhance the understanding and comparability of our operational performance and the underlying fundamentals, but this exclusion is not an indication that similar items may not recur and does not replace the comparable GAAP measures in the determination of overall profitability. For a reconciliation of the most directly comparable GAAP measures to these non-GAAP financial measures, refer to the "Reconciliation of Non-GAAP Financial Measures" beginning on the following page. 86
