¹ Non-GAAP Financial Measures:

Operating Income or Income excluding net realized gains (losses) and cumulative effect, net of tax is a common performance measurement for insurance companies. We believe this presentation enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business. We exclude net realized gains (losses) because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities. We exclude the cumulative effect of a change in accounting principle net of tax because this amount resulted in a one-time adjustment to income.

Underwriting income is calculated by subtracting losses and loss expenses, life and annuity benefits, policy acquisition costs and administrative expenses from net premiums earned. We use underwriting income and operating ratios to monitor the results of our operations without the impact of certain factors, including net investment income, other (income) expense, interest and income tax expense and net realized gains (losses). We believe the use of these measures enhances the understanding of our results of operations by highlighting the underlying profitability of our insurance business.

Tangible shareholders’ equity is shareholders’ equity less goodwill. See reconciliation of Non-GAAP Financial Measures on page 23 in the financial supplement.

These measures should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).

² The cumulative effect is a benefit resulting from the inclusion of a forfeiture rate on restricted stock in our stock compensation expense calculations, as required under Financial Accounting Standard (FAS) 123R.

³ Calculated using income excluding net realized gains (losses).

⁴ Book value per ordinary share is ordinary shareholders’ equity divided by the shares outstanding.
