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 may also enter into commodity swap contracts to hedge price changes in a certain commodity that impacts 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 December 31, 2013, we held foreign currency forward contracts to buy 114.7 million Mexican pesos and 15 million Canadian dollars and to sell 3.5 million Swiss francs and 24.7 million Mexican pesos.
