Investments, Debt and Equity Securities [Abstract]

Trading Securities, Policy [Policy Text Block]

Trading Securities

Trading securities are recorded at fair value with subsequent changes in fair value recorded as “Fair value gains (losses), net” in our condensed consolidated statements of operations and comprehensive income.

Available-for-sale Securities, Policy [Policy Text Block]

Available-for-Sale Securities

We measure available-for-sale (“AFS”) securities at fair value with unrealized gains and losses, recorded net of tax as a component of “Other comprehensive (loss) income” and we recognize realized gains and losses from the sale of AFS securities in “Investment gains, net” in our condensed consolidated statements of operations and comprehensive income.

Other-Than-Temporary Impairments

We evaluate available-for-sale securities for other-than-temporary impairment on a quarterly basis. An other-than-temporary impairment is considered to have occurred when the fair value of a debt security is below its amortized cost basis and we intend to sell or it is more likely than not that we will be required to sell the security before recovery. In such cases, we recognize in “Net other-than-temporary impairments” in our condensed consolidated statements of operations and comprehensive income, the entire difference between the amortized cost basis of the security and its fair value. An other-than-temporary impairment is also considered to have occurred if we do not expect to recover the entire amortized cost basis of a debt security even if we do not intend or it is not more likely than not we will be required to sell the security before recovery. We separate the difference between the amortized cost basis of the security and its fair value into the amount representing the credit loss, which we recognize in “Net other-than-temporary impairments” in our condensed consolidated statements of operations and comprehensive income, and the amount related to all other factors, which we recognize in “Other comprehensive (loss) income,” net of applicable taxes.
