Fair Value Disclosures [Abstract]
Fair Value	Fair Value Our financial instruments are presented at fair value in our condensed consolidated balance sheets, with the exception of our long-term debt. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models may be applied. Assets and liabilities recorded at fair value in our condensed consolidated balance sheets are categorized by hierarchical levels based upon the level of judgment associated with the inputs used to measure their fair values. Recurring fair value measurements are limited to investments in derivative instruments and certain equity securities. The fair value measurements of our derivative instruments are determined using models that maximize the use of the observable market inputs including interest rate curves and both forward and spot prices for currencies, and are classified as Level II under the fair value hierarchy. The fair values of our derivatives are included in Note 4. The fair value measurements of our investments in equity securities are determined using quoted market prices and are classified as Level I. The fair values of our investments in equity securities, and changes thereto, are immaterial to our consolidated financial position and results of operations. The fair value of our debt, excluding the Senior Notes, was estimated using interest rates on similar debt recently issued by companies with credit metrics similar to ours and is classified as Level II under the fair value hierarchy. The carrying value of our debt is included in Note 5 and, except for the Senior Notes, approximates fair value. The estimated fair value of our Senior Notes at September 30, 2013 was $473.1 million compared to the carrying value of $498.2 million. The estimated fair value of the Senior Notes is based on Level I quoted market rates. The carrying amounts of our other financial instruments (i.e., cash and cash equivalents, accounts receivable, net and accounts payable) approximated fair value due to their short-term nature at September 30, 2013 and December 31, 2012.
