Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes involves a significant amount of management judgment regarding interpretation of relevant facts and laws in the jurisdictions in which the Company operates. Future changes in applicable laws, projected levels of taxable income and tax planning could change the effective tax rate and tax balances recorded by the Company. In addition, tax authorities periodically review income tax returns filed by the Company and can raise issues regarding its filing positions, timing and amount of income or deductions, and the allocation of income among the jurisdictions in which the Company operates. A significant period of time may elapse between the filing of an income tax return and the ultimate resolution of an issue raised by a revenue authority with respect to that return. In the normal course of business the Company is subject to examination by taxing authorities throughout the world, including such major jurisdictions as Brazil, Canada, China, France, Germany, Ireland, Italy, Mexico, Switzerland, the Netherlands and the United States. In general, the examination of the Company’s material tax returns is complete for the years prior to 2001, with certain matters being resolved through appeals and litigation. In 2007, the Company received a notice from the IRS containing proposed adjustments to the Company's tax filings in connection with an audit of the 2001 and 2002 tax years. The IRS did not contest the validity of the Company's reincorporation in Bermuda. The IRS proposed to ignore the entities that hold the intercompany debt incurred in connection with the Company's reincorporation in Bermuda (the "2001 Debt") and to which the interest was paid and impose 30% withholding tax on a portion of the interest payments as if they were made directly to a company that was not eligible for reduced U.S. withholding tax under a U.S. income tax treaty. The IRS asserted that the Company owed additional taxes with respect to 2002 of approximately $84 million plus interest. In 2010, the Company received an amended notice from the IRS assessing penalties of 30% on the asserted underpayment of tax described above. In 2013, the Company received a Notice of Deficiency from the IRS for 2002 and the Company filed a petition in the United States Tax Court in November 2013 contesting this deficiency. In its January 2014 answer to the Company’s petition, the IRS asserted that the Company also owed 30% withholding tax on the portion of 2002 interest payments made on the 2001 Debt upon which it did not previously assert withholding tax. This increased the total tax liability proposed for 2002 to $109.0 million ($84 million referred to in the paragraph above plus an additional $25.0 million) plus 30% penalties and interest. In 2013, the Company received notices from the IRS containing proposed adjustments to the Company's tax filings in connection with an audit of the 2003-2006 tax years. In these notices, the IRS asserted that the Company owed a total of approximately $665 million of additional taxes, as described more fully in the two paragraphs below, in connection with the Company's interest payments on the 2001 Debt for the 2003-2006 period, plus penalties and interest on these unpaid taxes. The IRS continued to take the position on the 2001 Debt, which was retired at the end of 2011, that it previously took for the Company's 2002 tax year and which is described above. As a result of this recharacterization, the IRS asserted that the Company owed approximately $455.0 million of withholding tax for 2003-2006 plus 30% penalties and interest. The IRS also proposed to extend its position further and to treat all of the interest income from the 2001 Debt as creating earnings and profits at IR-Limited and, as a result, recharacterized the distributions made by IR-Limited during the 2002-2006 tax years as taxable dividends instead of as a return of capital. Consequently the IRS asserted that the Company owed approximately $210.0 million of income tax on these dividends plus penalties of 20% and interest. The Company strongly disagreed with the view of the IRS and filed a protest in January 2014 for the 2003-2006 tax years. Furthermore, a substantial amount of information was provided to the IRS in connection with its audit of our 2007-2011 tax years. We expected the IRS to propose similar adjustments with respect to the 2001 Debt, although the Company did not know how the IRS would apply its position to the different facts presented in those years or whether the IRS would take a similar position with respect to intercompany debt instruments not outstanding in prior years. During the three months ended June 30, 2015 the Company had extensive negotiations with the IRS on the terms of a settlement that was signed on July 17, 2015 to resolve all disputes described above with respect to the 2001 Debt, any similar issues related to other intercompany debt outstanding during the 2002-2011 period and all related issues including the issue of the recharacterized distributions. The resolution must be reported to the Congressional Joint Committee on Taxation (the “JCT”) for review and cannot be finalized until the IRS considers the views, if any, expressed by the JCT about the matter. This resolution covers the intercompany debt and related issues described above for the entire period from 2002-2011 and includes all aspects of the controversy before the U.S. Tax Court, the Appeals Division and the Examination Division of the IRS. Pursuant to the agreement with the IRS, no penalties will apply with regard to any of the tax years 2002-2011, the Company will pay $230 million in withholding tax, plus interest with respect to the 2002-2006 years and no additional tax will be owed with respect to these intercompany debt and related matters for the years 2007-2011. In connection with this resolution, the Company recorded a charge of approximately $227 million to income tax expense in the three months ended June 30, 2015 with the corresponding liability recorded to accrued expenses and other current liabilities. The Company expects to have a net cash outflow related to this matter in the second half of 2015 of approximately $375 million(consisting of the $230 million in tax and $145 million of interest net of tax benefit). We expect our available cash flow, committed credit lines and access to the capital markets will be sufficient to fund this tax obligation. Total unrecognized tax benefits as of June 30, 2015 and December 31, 2014 were $493.0 million and $343.8 million, respectively. The total amount of unrecognized tax benefits relating to the Company's tax positions is subject to change based on future events including, but not limited to, the settlements of ongoing audits and/or the expiration of applicable statutes of limitations. The Company believes that it has adequately provided for any reasonably foreseeable resolution of tax matters, but will adjust its reserves if events so dictate in accordance with GAAP. To the extent that the ultimate results differ from the original or adjusted estimates of the Company, the effect will be recorded in the Provision for income taxes.
