These contracts are recorded within prepaid expenses and other current assets in the consolidated balance sheets. Gains and losses resulting from currency exchange rate movements on these forward contracts are recognized in other income (expense) in the accompanying consolidated statements of operations in the period in which the exchange rates change and offset the foreign currency gains and losses on the underlying exposure being hedged.

Actual results could differ from those estimates and such differences may be material to the accompanying consolidated financial statements.</font></div></div>
