Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES The Company is responsible for filing consolidated U.S., foreign and combined, unitary or separate state income tax returns. The Company is responsible for paying the taxes relating to such returns, including any subsequent adjustments resulting from the redetermination of such tax liabilities by the applicable taxing authorities. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code, including, but not limited to requiring a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries that is payable over eight years (the "Transition Tax"), a reduction of the U.S. federal corporate tax rate from 35% to 21%, repeals the Domestic Manufacturing Deduction, a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries, new provisions designed to tax global intangible low-taxed income ("GILTI"), tax certain deductible base erosion payments called base erosion and anti-abuse tax (“BEAT”), and new interest expense limitation provisions. In relation to the initial analysis of the impact of the all tax law changes at December 31, 2017, the Company recorded a net tax expense of $4.3 million. This included a provisional expense for the U.S tax reform bill of $55.0 million, as well as a net benefit for the revaluation of deferred tax assets and liabilities of $50.7 million. The Company has not completed its accounting for the income tax effects of the Tax Act. Where the Company has been able to make reasonable estimates of the effects for which its analysis is not yet complete, the Company has recorded provisional amounts in accordance with SEC Staff Accounting Bulletin No. 118. Where the Company has not yet been able to make reasonable estimates of the impact of certain elements, the Company has not recorded any amounts related to those elements and has continued accounting for them in accordance with ASC 740 on the basis of the tax laws in effect immediately prior to the enactment of the Tax Act. The Company's accounting for the following impacted areas of the Tax Act is incomplete. However, the Company was able to make reasonable estimates of certain effects and, therefore, has recorded provisional amounts as follows: Revaluation of deferred tax assets and liabilities: The Tax Act reduces the U.S. federal corporate tax rate from 35% to 21% for tax years beginning after December 31, 2017. In addition, the Tax Act makes certain changes to the depreciation rules and implements new limits on the deductibility of certain executive compensation. The Company evaluated these changes and recorded a provisional benefit to net deferred taxes of $24.6 million at December 31, 2017. The Company is still completing its calculation of the impact of these changes on its deferred tax balances. As of June 30, 2018, the Company has refined the estimate of the impact of the Tax Act on the deductibility of certain executive compensation which resulted in a current period benefit to net deferred taxes of $2.9 million. Transition Tax on unrepatriated foreign earnings: The Transition Tax on unrepatriated foreign earnings is a tax on previously untaxed accumulated and current earnings and profits ("E&P") of the Company's foreign subsidiaries. To determine the amount of the Transition Tax, the Company must determine, among other factors, the amount of post-1986 E&P of its foreign subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. The Company was able to make a reasonable estimate of the Transition Tax and recorded a provisional Transition Tax expense of $51.8 million at December 31, 2017. As of June 30, 2018, the Company has refined the estimate resulting in a current period benefit of $10.1 million. The Company is continuing to gather additional information to finalize the amount of the Transition Tax, to complete its calculation of E&P, and complete its determination of non-U.S. income taxes paid. Global intangible low taxed income: The Tax Act created a new requirement that certain income (i.e., GILTI) earned by foreign subsidiaries must be included currently in the gross income of the U.S. shareholder. Under U.S. GAAP, the Company is permitted to make an accounting policy election to either treat taxes due on future inclusions in U.S. taxable income related to GILTI as a current-period expense when incurred or to factor such amounts into the Company's measurement of its deferred taxes. The Company has made the election to treat taxes due on future inclusions related to GILTI as current period expense. The Company was able to make reasonable estimates to calculate a provision that is included in the current period expense. The Company will continue to evaluate and update this provision and the application of ASC 740. The overall effective income tax rate was 11.2% and 17.7% for the three and six months ended June 30, 2018, respectively and 25.4% and 26.5% for the three and six months ended June 30, 2017, respectively. The reductions in the current year effective tax rate are due to the tax benefits related to the Tax Act as discussed above. As of June 30, 2018 and December 31, 2017, the liability for income taxes associated with uncertain tax positions was $6.9 million, of which $4.4 million, if recognized, would favorably affect the Company’s effective tax rate. The Company includes interest and penalties related to uncertain tax positions in income tax expense. As of June 30, 2018, the total accrued interest and penalties are $0.7 million and $0.1 million, respectively. As of December 31, 2017, the total accrued interest and penalties were $0.7 million and $0.1 million, respectively. At this time, the Company believes it is reasonably possible that unrecognized tax benefits of approximately $5.2 million may change within the next 12 months due to the expiration of statutory review periods and current examinations. With limited exceptions, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for years before 2014.
