Forward and Swap Contracts

From time to time, we enter into forward contracts to hedge potential foreign currency gains and losses that arise from transactions denominated in foreign currencies, including inter-company transactions. We also enter into commodity swap contracts to hedge price changes in commodities that impact raw materials included in our cost of revenues. We do not use derivative financial instruments for speculative purposes. These contracts are not designated as hedging instruments and do not receive hedge accounting treatment; therefore, changes in their fair value are not deferred but are recognized immediately in the Consolidated Statements of Income. At September 30, 2012, we held foreign currency forward contracts to buy 106.3 million Mexican pesos. At September 30, 2012, we held commodity swap contracts to buy 286,000 pounds of nickel.
