Fair Value Measurement

Note 10 Fair Value Measurement

The Company bases fair value on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We have adopted a fair value hierarchy that prioritizes observable and unobservable inputs used to measure fair value into three broad levels, which are described below:

Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. The fair value hierarchy gives the highest priority to Level 1 inputs.

Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data.

Level 3: Unobservable inputs are used when little or no market data is available. The fair value hierarchy gives the lowest priority to Level 3 inputs.

In determining fair value, the Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible and also considers counterparty credit risk in its assessment of fair value.

The Company’s derivative instruments and hedging activities and pension assets qualify as financial assets and liabilities whose fair value is measured on a recurring basis each reporting period. Fair value measurement disclosures for our derivative instruments and hedging activities are located within Note 8. The carrying amounts of financial instruments comprising cash and cash equivalents, short-term investments and accounts receivable approximate their fair values due to their short-term nature. The carrying value of the Company’s long-term debt approximates its fair value because interest charged on the loan balance is variable. There were no significant changes to interest rates during the period.

Certain Company assets are required to be recorded at fair value on a non-recurring basis when events and circumstances indicate that the carrying value may not be recoverable. As of June 30, 2012 and 2011, the Company did not realize any changes to the fair value of these assets due to events that negatively impacted their recoverability.
