NYSE Euronexts short term financial investments generally are classified as available-for-sale securities and are carried at fair value as of trade date with the unrealized gains and losses, net of tax, reported as a component of other comprehensive income. Interest income on debt securities, bank deposits and other interest rate investments, including amortization of premiums and accretion of discounts, is accrued and recognized over the life of the investment. The specific identification method is used to determine realized gains and losses on sales of investments, which are reported in interest and investment income in the consolidated statements of income.
NYSE Euronext regularly reviews its investments to determine whether a decline in fair value below the cost basis is other than temporary. If events and circumstances indicate that a decline in the value of the assets has occurred and is deemed to be other-than-temporary, the carrying value of the security is reduced to its fair value and a corresponding impairment is charged to earnings.
