Impairment of Equity Securities
Equity securities that do not have readily determinable fair values are measured at cost minus impairment (the practicality exception). When a qualitative assessment indicates that impairment exists, the cost basis of the security is written down to fair value and the amount of the write?down is accounted for as a realized loss and included in earnings.
