Accounting standards require entities to measure certain assets or liabilities at fair value. These rules require accountants to make subjective assessments in determining when impairment should be considered other than temporary, and if so, to write down the impaired asset to its fair value with a charge to current-period earnings. Companies are generally reluctant to take such impairment charges because once a new cost basis is established from the write-down, any subsequent appreciation in fair value of the impaired security may not be recognized until the security is sold. At the same time, the decision not to recognize impairment is subject to close scrutiny by analysts and regulators.
