Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Non-financial assets and liabilities of the Company measured at fair value include any long-lived assets or equity method investments that are impaired in a currently reported period. The authoritative guidance also describes three levels of inputs that may be used to measure fair value:

Level 1 —	quoted prices in active markets for identical assets and liabilities
Level 2 —	observable inputs other than quoted prices in active markets for identical assets and liabilities
Level 3 —	unobservable inputs in which there is little or no market data available, which require the reporting entity to develop its own assumptions

As of June 30, 2012, the Company’s financial instruments included cash equivalents, restricted cash, accounts receivable, short-term bank borrowings, accounts payable, long-term secured debt and a cross-currency derivative contract. Cash equivalents consist of short-term highly liquid, income-producing investments, all of which have original maturities of 90 days or less, including money market funds. The carrying amount of restricted cash, accounts receivable, short-term bank borrowings and accounts payable approximate fair value due to the short-term maturities of these instruments. The Company’s Credit Facilities carry a floating rate of interest.  The fair value of our Credit Facilities approximates book value as of June 30, 2012 because our interest rate was at the one month LIBOR plus an applicable margin.  See Note 7 for further discussion of our Credit Facilities.

The Company’s cross-currency derivative instrument is the only financial instrument recorded at fair value on a recurring basis. This instrument consists of an over-the-counter contract, which is not traded on a public exchange. The fair value of the swap contract is determined based on inputs that are readily available in public markets or can be derived from information available in publicly quoted markets. Therefore, the Company has categorized the swap contract as a Level 2 derivative financial instrument. The Company also considers counterparty credit risk and its own credit risk in its determination of estimated fair values. The Company has consistently applied these valuation techniques in all periods presented.
