(1) Non-GAAP Financial Measure: Operating income or income excluding net realized gains (losses), 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) and net realized gains (losses) included in other income (expense) related to partially-owned entities because the amount of these gains (losses) is heavily influenced by, and fluctuates in part according to, the availability of market opportunities.
