Reclassification From Accumulated Other Comprehensive Income to Earnings
As discussed in Financial Investments, of Note 2, Summary of Significant Accounting Policies, we account for financial investments in accordance with SFAS 115. We determine the fair value of our available-for-sale investment securities based on quoted market prices. When the fair value of an available-for-sale investment security is less than its cost for an extended period, we consider whether there is an other-than-temporary impairment in the value of the security. If, in our judgment, an other-than-temporary impairment exists, the cost basis of the available-for-sale security is written down to the then-current fair value, and the unrealized loss is transferred from accumulated other comprehensive income, as an immediate reduction of current earnings. In connection with our business combination of OMX AB, we acquired a long-term available-for-sale investment security which was accounted for under SFAS 115. In the fourth quarter of 2008, we recorded an other-than-temporary impairment on this long-term available-for-sale investment security and realized a loss of $34.9 million. This charge was included in asset impairment charges within other income (expense), net in the Consolidated Statements of Income
