Derivative Financial Instruments [Abstract] |
Derivative Financial Instruments | 4. Derivative Financial Instruments Cash Flow Hedges At March 31, 2011, the Company had forward contracts outstanding to hedge cash flow exposure at the Company's wholly-owned Austrian subsidiary, AMSC Windtec GmbH ("AMSC Austria"), with aggregate U.S. dollar equivalent notional amounts of $40.9 million. These contracts expired at various dates through March 2012. At March 31, 2011, the Company determined, that these forward foreign exchange contracts outstanding were no longer effective hedges based on the Company's determination that the original forecasted transactions were not probable of occurring by the end of the originally specified time period. As a result, the Company reclassified accumulated gains of $1.6 million from accumulated other comprehensive income (loss) to other income (expense), net, in the accompanying consolidated statements of operations. At March 31, 2012, the Company had no forward foreign exchange contracts outstanding. The fair value amounts of asset derivatives included in prepaid expenses and other current assets and liability derivatives included in accounts payable and accrued expenses in the consolidated balance sheets related to forward foreign exchange contracts as of March 31, 2011 were as follows (in thousands):
