SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Mar. 31, 2012
Accounting Policies [Abstract]
Basis of Presentation	The interim consolidated financial statements reflect all adjustments which in the opinion of management are necessary for a fair statement of results of operations, comprehensive income, financial condition, cash flows and stockholders' equity for the periods presented. Except as otherwise disclosed, all such adjustments are of a normal recurring nature. The interim consolidated financial statements have been compiled without audit. Operating results for the interim periods are not necessarily indicative of the results that may be expected for the full year. These interim consolidated financial statements should be read in conjunction with the audited consolidated financial statements included in the Company’s 2011 Annual Report on Form 10-K. The year-end balance sheet data was derived from the audited financial statements as of December 31, 2011, but does not include all the disclosures required by accounting principles generally accepted in the United States (“GAAP”).
Use Of Estimates	The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Earnings Per Share	The Company’s unvested restricted common stock and unvested restricted stock units that contain non-forfeitable rights to dividends are participating securities and, therefore, are included in the earnings allocation in computing earnings per share using the two-class method. Basic earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding. Diluted earnings per common share is calculated by dividing net income, adjusted for earnings allocated to participating securities, by the weighted average number of common shares outstanding after giving effect to all potentially dilutive common shares outstanding during the period. In calculating losses on a fully diluted basis, certain potentially dilutive securities, which would otherwise reduce the loss per share, are excluded from the calculation. Potentially dilutive common shares include the dilutive effect of outstanding stock options and performance share units granted under the Company’s Amended and Restated Employee Long-Term Incentive Plan and its Amended and Restated Non-Employee Director Long-Term Incentive Plan. Earnings allocable to participating securities include the portion of dividends declared as well as the portion of undistributed earnings during the period allocable to participating securities.
Adoption of New Accounting Standards	On January 1, 2012, the Company adopted an amendment issued by the Financial Accounting Standards Board ("FASB") to the accounting standards related to fair value measurements and disclosure requirements. This standard provides certain amendments to the existing guidance on the use and application of fair value measurements and maintains a definition of fair value that is based on the notion of exit price. The adoption of this standard did not have a material impact on the Company’s consolidated financial statements. On January 1, 2012, the Company adopted amendments issued by the FASB to the accounting standards related to the presentation of comprehensive income. These standards revise the manner in which entities present comprehensive income in their financial statements and remove the option to present items of other comprehensive income in the statement of changes in stockholders’ equity. These standards require an entity to report components of comprehensive income in either (1) a continuous statement of comprehensive income, or (2) two separate but consecutive statements of net income and other comprehensive income. The Company modified its financial statements presentation using the latter alternative. On January 1, 2012, the Company adopted revised guidance issued by the FASB related to the testing of goodwill for impairment. Under the revised guidance, an entity has the option to perform a qualitative assessment of whether it is more-likely-than-not that a reporting unit’s fair value is less than its carrying value prior to performing the two-step quantitative goodwill impairment test. If, based on the qualitative factors, an entity determines that the fair value of the reporting unit is greater than its carrying amount, then the entity would not be required to perform the two-step quantitative impairment test for that reporting unit. However, if the qualitative assessment indicates that it is not more-likely-than-not that the reporting unit’s fair value exceeds its carrying value, then the quantitative assessment must be performed. An entity is permitted to perform the qualitative assessment on none, some or all of its reporting units and may also elect to bypass the qualitative assessment and begin with the quantitative assessment of goodwill impairment. This amendment did not have a material impact on the Company’s consolidated financial statements.
Derivative Financial Instruments	The Company uses derivative financial instruments to manage its exposure to market risks for changes in interest rates and foreign currencies. This strategy includes the use of interest rate swap agreements, forward starting interest rate swap agreements, treasury lock agreements and foreign currency forward contracts to manage its exposure to movements in interest and currency rates. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. These policies prohibit holding or issuing derivative financial instruments for speculative purposes. The Company does not enter into derivative financial instruments that contain credit-risk-related contingent features or requirements to post collateral.
Interest Rate Risk	The Company is exposed to interest rate risk on its cash and cash equivalents and its debt obligations. Interest income earned on cash and cash equivalents may fluctuate as interest rates change; however, due to their relatively short maturities, the Company does not hedge these assets or their investment cash flows and the impact of interest rate risk is not material. The Company's debt obligations consist of fixed-rate and variable-rate debt instruments. The Company's primary objective is to achieve the lowest overall cost of funding while managing the variability in cash outflows within an acceptable range. In order to achieve this objective, the Company has entered into interest rate swaps. Interest rate swaps involve the periodic exchange of payments without the exchange of underlying principal or notional amounts. Net settlements between the counterparties are recognized as an adjustment to interest expense.
Foreign Currency Risk	The Company is exposed to market risk for changes in foreign exchange rates primarily under certain intercompany receivables and payables. Foreign exchange forward contracts are used to mitigate the exposure of the eventual net cash inflows or outflows resulting from these intercompany transactions. The objective is to hedge a portion of the forecasted foreign currency risk over a rolling 12-month time horizon to mitigate the eventual impacts of changes in foreign exchange rates on the cash flows of the intercompany transactions. As of March 31, 2012, the gross notional amount of foreign currency forward contracts in U.S. dollars was $34.4 million and principally consists of contracts in Swedish krona. The Company does not designate these derivative instruments as hedges under current accounting standards unless the benefits of doing so are material. The Company's foreign exchange exposure is not material to the Company's consolidated financial condition or results of operations. The Company does not hedge its net investment in non-U.S. subsidiaries because it views those investments as long-term in nature.

Disclosure of accounting policy for its derivative instruments and hedging activities. Disclosure may include: (1) Each method used to account for derivative financial instruments and derivative commodity instruments ("derivatives"); (2) the types of derivatives accounted for under each method; (3) the criteria required to be met for each accounting method used, including a discussion of the criteria required to be met for hedge or deferral accounting and accrual or settlement accounting (for example, whether and how risk reduction, correlation, designation, and effectiveness tests are applied); (4) the accounting method used if the criteria specified for hedge accounting are not met; (5) the method used to account for termination of derivatives designated as hedges or derivatives used to affect directly or indirectly the terms, fair values, or cash flows of a designated item; (6) the method used to account for derivatives when the designated item matures, is sold, is extinguished, or is terminated. In addition, the method used to account for derivatives designated to an anticipated transaction, when the anticipated transaction is no longer likely to occur; and (7) where and when derivatives, and their related gains or losses are reported in the statement of financial position, cash flows, and results of operations and (8) an accounting policy decision to offset fair value amounts with counterparties. An entity may also describe its embedded derivatives, and the method(s) used to determine the fair values of derivatives and any significant assumptions used in such valuations.
