Operating Income (Loss)Although the investment of premiums to generate income and realized investment gains (or losses) is an integral part of our operations, the determination to realize investment gains (or losses) is independent of the underwriting process and is heavily influenced by the availability of market opportunities. Furthermore, many users believe that the timing of the realization of investment gains (or losses) is somewhat opportunistic for many companies. Foreign exchange losses (gains) in our Consolidated Statements of Operations are primarily driven by the impact of foreign exchange rate movements on net insurance-related liabilities. However, this movement is only one element of the overall impact of foreign exchange rate fluctuations on our financial position. In addition, we recognize unrealized foreign exchange losses (gains) on our available-for-sale investments in other comprehensive income and foreign exchange losses (gains) realized upon the sale of these investments in net realized investment gains (losses). These unrealized and realized foreign exchange movements generally offset a large portion of the foreign exchange losses (gains) reported separately in earnings, thereby minimizing the impact of foreign exchange rate movements on total shareholders’ equity. As such, the Statement of Operations foreign exchange losses (gains) in isolation are not a fair representation of the performance of our business. Losses on repurchase of preferred shares arise from capital transactions and, therefore, are not reflective of underlying business performance. In this regard, certain users of our financial statements evaluate earnings excluding after-tax net realized investment gains (losses), foreign exchange losses (gains) and losses on repurchase of preferred shares to understand the profitability of recurring sources of income. We believe that showing net income available to common shareholders exclusive of net realized gains (losses), foreign exchange losses (gains) and losses on repurchase of preferred shares reflects the underlying fundamentals of our business. In addition, we believe that this presentation enables investors and other users of our financial information to analyze performance in a manner similar to how our management analyzes the underlying business performance. We also believe this measure follows industry practice and, therefore, facilitates comparison of our performance with our peer group. We believe that equity analysts and certain rating agencies that follow us, and the insurance industry as a whole, generally exclude these items from their analyses for the same reasons.
