Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES On December 22, 2017, Staff Accounting Bulletin No. 118 (“SAB 118”) was issued to address the application of GAAP in situations when a registrant does not have the necessary information available, prepared, or analyzed (including computations) in reasonable detail to complete the accounting for certain income tax effects of the Tax Act. Pursuant to the guidance we recognized the provisional effects of the enactment of the Tax Act for which measurement could be reasonably estimated. We continue to monitor certain aspects of the Tax Act and may refine our assessment as a result of any further related regulatory guidance that may be issued by the U.S. Treasury. Pursuant to SAB 118, adjustments to the provisional amounts recorded as of December 31, 2017 that are identified within a subsequent measurement period of up to one year from the enactment date will be included as an adjustment to tax expense from continuing operations in the period the amounts are determined. We recognized no measurement period adjustments during the three months ended March 31, 2018. The effective tax rates for the three months ended March 31, 2018 and 2017 differed from the federal statutory rate applied to income and losses before income taxes primarily as a result of the mix of income, losses and tax rates between tax jurisdictions and valuation allowances. We have valuation allowances recorded to reduce certain deferred tax assets to amounts that are more likely than not to be realized. The valuation allowances relate to the potential inability to realize our deferred tax assets associated with amortization and net operating loss carryforwards in the U.S. and net operating loss carryforwards in non-U.S. jurisdictions. We intend to maintain our valuation allowances until sufficient positive evidence exists (such as cumulative positive earnings and estimated future taxable income) to support their reversal. As of March 31, 2018, we had $4.3 of unrecognized tax benefits. $3.2 of the gross unrecognized tax benefits, if recognized, would affect the annual effective tax rate. We recognize interest and penalties related to uncertain tax positions within “Provision for income taxes” in the Consolidated Statements of Comprehensive Income (Loss). As of March 31, 2018, we had approximately $0.9 of accrued interest related to uncertain tax positions. The 2009 through 2016 tax years remain open to examination. During the fourth quarter of 2013, a non-U.S. taxing jurisdiction commenced an examination of our tax returns for the tax years ended December 31, 2012, 2011, 2010 and 2009 that is anticipated to be completed within six months of the reporting date. During the second quarter of 2017, another non-U.S. taxing jurisdiction commenced an examination of our tax return for tax year ended December 31, 2015 that is anticipated to be completed within three months of the reporting date.
