Foreign Currency Risk
The Company has significant international sales and purchase transactions in foreign currencies. The Company enters into foreign currency forward contracts and may enter into currency options with durations of generally less than 30 days to hedge such transactions. These derivative instruments are employed to eliminate or minimize certain foreign currency exposures that can be confidently identified and quantified. Generally, these instruments are not designated as hedges for accounting purposes, and changes in the fair value of these instruments are recognized immediately in other income (expense). The Companys currency hedging activities are focused on exchange rate movements, primarily in Canada, Mexico, the United Kingdom, Western European countries that use the euro as a common currency, Australia, India, Israel and Switzerland. At December 31, 2007 and 2006, the Company had forward exchange contracts to purchase various foreign currencies in the amount of $2.6 billion and $1.9 billion, respectively, and to sell various foreign currencies in the amount of $0.9 billion and $1.0 billion, respectively.
