Derivative Financial Instruments and Fair Value Measurements [Abstract]  
Derivative Financial Instruments and Fair Value Measurements
We are exposed to various risks relating to our ongoing business operations. Among these risks are foreign currency exchange rate risk and interest rate risk, which are managed through the use of derivative instruments. In certain circumstances, we enter into foreign currency forward exchange contracts ("forward contracts") to reduce the effects of fluctuating foreign currency exchange rates on our cash flows denominated in foreign currencies. Our exposure to market risk for changes in interest rates relates primarily to our Long-Term Debt obligations. We have historically managed interest rate risk through the use of a combination of fixed and variable rate borrowings and interest rate swap agreements. In accordance with current accounting guidance on derivative instruments and hedging activities, we record all of our derivative instruments as either an asset or liability measured at their fair value.
