[1] The company routinely uses foreign currency exchange contracts to offset its net exposures, by currency, related to the 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 recorded in other income, net and the related tax impact is recorded in provision for income taxes on the interim Consolidated Income Statements.

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