Income Tax Expense (Benefit) [Abstract]
Income Taxes	11. INCOME TAXES The Company’s net unrecognized tax benefits totaled approximately $37.6 million and $79.2 million as of June 30, 2012 and December 31, 2011, respectively. The decrease in the net unrecognized tax benefits when comparing June 30, 2012 to December 31, 2011 was primarily due to the closure of IRS examinations for the tax years 2004 through 2008. In addition, certain deferred tax liabilities were reclassified from short-term to long-term as currently pending matters have been closed with the IRS. All amounts included in the balance at June 30, 2012 for tax positions would affect the annual effective tax rate. The Company has accrued approximately $0.5 million for the payment of interest and penalties as of June 30, 2012. The Company and one or more of its subsidiaries is subject to federal income taxes in the United States, as well as income taxes of multiple state and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years prior to 2008. In June 2010, the Company reached a settlement in principle with the Internal Revenue Service (“IRS”) regarding certain previously disclosed income tax deficiencies asserted in a Revenue Agent’s Report (the “RAR”), the terms of which were approved in June 2012 (the "Final Approval"). Under the terms of the settlement, the Company agreed to an assessment of income tax deficiencies in full settlement of all open claims under the RAR and resolved with finality for future years all of the transfer pricing issues raised in the RAR. Based on this, the Company incurred a charge of $13.1 million in 2010 in accordance with the authoritative guidance. In connection with the Final Approval, the Company finalized the tax deficiency calculations and formally closed all of its open issues with the IRS relating to the 2004 and 2005 tax years. Because there were no changes from the agreement reached in 2010, there were no additional amounts included in income tax (benefit) expense during the second quarter of 2012. Also, in June 2012, the Company closed its IRS examination for the 2006 through 2008 tax years. The Company recognized a net tax benefit of $24.2 million in the second quarter of 2012 related to the closing of tax audits with the IRS for the 2006 through 2008 tax years, the impact of the closure on subsequent years and the reduction of the Company's uncertain tax positions for the closed tax years. In the ordinary course of global business, there are transactions for which the ultimate tax outcome is uncertain; thus, judgment is required in determining the worldwide provision for income taxes. The Company provides for income taxes on transactions based on its estimate of the probable liability. The Company adjusts its provision as appropriate for changes that impact its underlying judgments. Changes that impact provision estimates include such items as jurisdictional interpretations on tax filing positions based on the results of tax audits and general tax authority rulings. Due to the evolving nature of tax rules combined with the large number of jurisdictions in which the Company operates, it is possible that the Company’s estimates of its tax liability and the realizability of its deferred tax assets could change in the future, which may result in additional tax liabilities and adversely affect the Company’s results of operations, financial condition and cash flows.

The Company reviews deferred tax assets periodically for recoverability and makes estimates and judgments regarding the expected geographic sources of taxable income and gains from investments, as well as tax planning strategies in assessing the need for a valuation allowance. The Company maintains certain strategic management and operational activities in overseas subsidiaries and its foreign earnings are taxed at rates that are generally lower than in the United States. The Company does not expect to remit earnings from its foreign subsidiaries. The Company’s effective tax rate was approximately (7.6)% and 19.1% for the three months ended June 30, 2012 and 2011, respectively, and 5.8% and 18.2% for the six months ended June 30, 2012 and 2011, respectively. The decrease in the effective tax rate when comparing the three and six months ended June 30, 2012 to the three and six months ended June 30, 2011 was primarily due to the impact of the IRS settlement for the tax years 2006 through 2008. The Company’s effective tax rate generally differs from the U.S. federal statutory rate of 35% due primarily to lower tax rates on earnings generated by the Company’s foreign operations that are taxed primarily in Switzerland.
