Foreign Currency Exchange Rate Risk Management
The Company entered into forward contracts during fiscal 2011 to mitigate exposure to exchange rate fluctuations on Euro-denominated fixed asset purchases, which were designated as cash flow hedges for accounting purposes. These foreign currency forward contracts are measured using forward exchange rates based on observable exchange rates quoted in an active market and are classified as a Level 2 fair value measurement under the fair value hierarchy. In the first quarter of fiscal 2012, the Company determined that the forecasted transaction was no longer probable, de-designated these contracts as hedges and subsequently terminated the contracts. The nominal amount and fair value of these forward contracts, the amounts reclassified from accumulated other comprehensive income (loss) and the realized losses recorded in other income (expense), net during the period were not material to the Unaudited Condensed Consolidated Financial Statements.
