Derivative Instruments

We 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 on the condensed consolidated balance sheets at the end of each reporting period and expire within 90 days. In the three and six months ended May 31, 2013 and May 31, 2012, realized and unrealized gains (losses) of $0.6 million, $(0.5) million, $2.5 million and $0.3 million, respectively, from our forward contracts were recognized in other income (expense) in the condensed consolidated statements of income. These losses were substantially offset by realized and unrealized 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):
