Fair Value Measurement

Fair Value Measurement

The accounting guidance on fair value measurement establishes a hierarchy with three levels of inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets and liabilities, considered to be the most reliable evidence of fair value, and should be used whenever available. Level 2 inputs are observable prices that are not quoted on active exchanges. Level 3 inputs are unobservable inputs used for measuring the fair value of assets or liabilities.

Assets and liabilities reported at fair value on a recurring basis:

Assets and liabilities reported at fair value on a nonrecurring basis:

As a result of finalizing a restructuring plan, as discussed in Note 8, “Business Restructuring”, long-lived assets with a carrying amount of $10 million were written-down to their fair value of $7 million, resulting in a charge of $3 million, which was included in the business restructuring expense reported in the six months ended June 30, 2012. These long-lived assets were valued using Level 3 inputs.
