Companies are now required to classify temporary investments in all debt securities and equity securities with readily determinable fair values as trading, available for sale, and (for debt securities only ) held to maturity. Temporary investments in equity securities that do not have readily determinable fair values are reported in the balance sheet at fair value. Unrealized gains and losses for trading securities are reported in earnings, while unrealized gains and losses for available for-sale securities are reported as a component of other comprehensive income.
