On a pre-tax basis, net foreign exchange losses for the 2012 third quarter were $16.9 million (net unrealized losses of $17.1 million and net realized gains of $0.2 million), compared to net foreign exchange gains for the 2011 third quarter of $60.0 million (net unrealized gains of $62.8 million and net realized losses of $2.8 million). The 2012 third quarter net foreign exchange losses primarily resulted from the weakening of the U.S. Dollar against the Euro, British Pound Sterling and other major currencies during the period. Net unrealized foreign exchange gains or losses result from the effects of revaluing the Company’s net insurance liabilities required to be settled in foreign currencies at each balance sheet date. The Company’s strategy has been to hold investments in foreign currencies which are intended to mitigate its exposure to foreign currency fluctuations in its net insurance liabilities. Changes in the value of such investments due to foreign currency rate movements are reflected as a direct increase or decrease to shareholders’ equity and are not included in the consolidated statements of income. As a result of the current financial and economic environment as well as the potential for additional investment returns, the Company has not matched a portion of its projected liabilities in foreign currencies with investments in the same currencies and may not match such amounts in future periods, which could increase the Company’s exposure to foreign currency fluctuations and increase the volatility of the Company’s shareholders’ equity.
