Other Income and Expenses [Abstract]
Other Income (Expense), net	Other Income (Expense), net Other income (expense), net, consists primarily of foreign currency remeasurement gains and losses. We have a significant amount of foreign-denominated debt on our U.S. dollar-denominated balance sheet. The translation of that debt is reported in other income (expense), net each period, except for our 4.625% Senior Notes, which qualify as a hedge of our net investment in foreign operations (see Note 6). Such gains or losses are unrealized until repayment of the debt and relate to the weakening or strengthening, respectively, of the euro against the U.S. dollar. Recently, the U.S. dollar has strengthened against most foreign currencies. For additional information, see Note 13.
