Fair Value
Note 10 — Fair Value
     Non-financial assets measured at fair value on a non-recurring basis principally include real estate assets and assets held for sale, which are measured for impairment. In second quarter 2011, a real estate asset was remeasured and reported at fair value due to events or circumstances that indicated the carrying value may not be recoverable. We determined estimated fair value based on the present value of future probability weighted cash flows expected from the sale of the long-lived asset. As a result, we recognized asset impairment of $450,000 in second quarter 2011. The carrying value of this asset may have subsequently increased or decreased from the fair value reflected due to activity that has occurred since the measurement date.

     We elected not to use the fair value option for cash and cash equivalents, accounts receivable, other current assets, variable debt, accounts payable and other current liabilities. The carrying amounts of these financial instruments approximate their fair values due to their short-term nature or variable interest rates. We determine the fair value of fixed rate financial instruments using quoted prices for similar instruments in active markets.
