Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivative Instruments | Derivative Instruments We generally use forward contracts that are not designated as hedging instruments to hedge economically the impact of the variability in exchange rates on accounts receivable and collections denominated in certain foreign currencies. We generally do not hedge the net assets of our international subsidiaries. All forward contracts are recorded at fair value in other current assets or other current liabilities on the consolidated balance sheets at the end of each reporting period and expire within 90 days. In fiscal years 2013, 2012 and 2011, realized and unrealized gains (losses) of $1.1 million, $(0.2) million, and $(1.2) million, respectively, from our forward contracts were recognized in other income (expense) in the consolidated statements of income. These gains and losses were substantially offset by realized and unrealized losses and gains on the offsetting positions. The table below details outstanding foreign currency forward contracts where the notional amount is determined using contract exchange rates (in thousands):

Forward contracts to purchase U.S. dollars | 22,483 |  |  | 92 |  |  | 31,465 |  |  | (190 | )
Total | $ | 48,499 |  |  | $ | 171 |  |  | $ | 37,918 |  |  | $ | (186 | )
In the past, we used foreign currency option contracts that were not designated as hedging instruments to hedge economically a portion of forecasted international cash flows for up to one year in the future. All foreign currency option contracts were recorded at fair value in other current assets on the consolidated balance sheets at the end of each reporting period and expired within one year. In fiscal year 2011, mark-to-market losses of $0.5 million on foreign currency option contracts were recorded in other income (expense) in the consolidated statements of income. We did not hold any option contracts during fiscal years 2013 and 2012.
