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. In the current quarter, the Company has revised its accounting for the income tax effects of the Tax Act. The Company has adjusted the provisional amounts previously recorded in accordance with SEC Staff Accounting Bulletin No. 118. As such, the Company has included the following tax provisions in its financial statements as of September 30, 2018: 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. As a result of the completion of its 2017 U.S. corporate tax return in the three months ended September 30, 2018, the Company has adjusted its US deferred tax balances which has resulted in a current period benefit of $3.2 million. The Company has revised its calculation of the impact of these changes on its deferred tax balances. As of September 30, 2018, the Company has reviewed its analysis of the impact of the Tax Act on the deductibility of certain executive compensation. As a result, no further adjustments were made as of September 30, 2018. 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 September 30, 2018, the Company has revised its calculation of the Transition Tax which resulted in a benefit of $3.3 million and $13.4 million for the three and nine months ended September 30, 2018. 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: 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 16.2% and 17.2% for the three and nine months ended September 30, 2018, respectively, and 15.7% and 23.4% for the three and nine months ended September 30, 2017, respectively. The increase in the effective tax for the three months ended September 30, 2018 is due to a deferred tax net benefit recorded in the prior three month period ended September 30, 2017. The decrease in the effective tax for the nine months ended September 30, 2018 is due to the tax benefits related to the Tax Act as discussed above, a higher earnings mix in lower tax jurisdictions and the release of uncertain tax positions due to the expiration of statutes. During the current three month period ending September 30, 2018, certain statutes have expired related to uncertain tax positions that were previously recorded resulting in a $2.4 million reduction to the liability for uncertain tax positions, $1.1 million of which favorably affected the Company’s effective tax rate. As of September 30, 2018, the liability for income taxes associated with uncertain tax positions was $4.5 million, of which $3.3 million, if recognized, would favorably affect the Company’s effective tax rate. As of 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. During the current three month period ending September 30, 2018, certain statutes have expired related to uncertain tax positions that were previously recorded. The net reduction in accrued interest expense related to these positions totaled $0.3 million which favorably affected the Company’s effective tax rate. As of September 30, 2018, the total accrued interest and penalties are $0.6 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 $4.5 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.
