[2] The company routinely uses forward exchange contracts to offset its net exposures, by currency, related to its foreign currency-denominated monetary assets and liabilities. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes on net monetary asset positions. The net pre-tax exchange gains and losses are partially offset by the associated tax impact.

[3] Miscellaneous income and expenses, net, generally includes interest items, insurance recoveries, litigation settlements and other items.
