1)Income (loss) excluding net realized gains (losses) on investments and the tax effect of net realized gains (losses) on investments is a common performance measurement. 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) on investments because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities. This measure should not be viewed as a substitute for net income determined in accordance with generally accepted accounting principles (GAAP).

2) Diluted book value per ordinary share is ordinary shareholders' equity and net proceeds from assumed conversions of outstanding in-the-money options divided by the sum of shares outstanding and the number of options assumed issued.
