Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the “Tax Act”). Effective January 1, 2018, the Tax Act establishes a corporate income tax rate of 21%, replacing the 35% rate, and creates a territorial tax system rather than a worldwide system, which generally eliminates the U.S. federal income tax on dividends from foreign subsidiaries. The transition to the territorial system included a one-time deemed repatriation transition tax (“Transition Tax”) on certain foreign earnings previously untaxed in the United States. The Company has made reasonable estimates for certain provisions under the Tax Act and recorded a provisional net benefit to income tax expense of $1.2 million related to its enactment in its income tax expense for the year ended December 31, 2017. This net benefit included a provisional deferred tax benefit of $3.0 million related to revaluing the net U.S. deferred tax liabilities to reflect the lower U.S. corporate tax rate. The deferred tax benefit was offset by a provision of $1.8 million related to the Transition Tax. In general, the Transition Tax imposed by the Tax Act results in the taxation of foreign earnings and profits (“E&P”) at a 15.5% rate on liquid assets and 8% on the remaining unremitted foreign E&P, both net of foreign tax credits. The provisional amounts for the Transition Tax recorded by the Company in 2017 included the undistributed E&P for all the Company’s foreign subsidiaries. Additional provisions of the Tax Act which may have an impact to the Company beginning in 2018 include, but are not limited to, the repeal of the domestic production deduction, limitations on interest expense deductions, accelerated depreciation that will allow for full expensing of qualified property, provisions related to performance-based executive compensation and other international provisions resulting from the territorial tax system established, as noted above. The Company has included provisional estimates of the impact of these changes, as applicable, in its estimated tax rate for the first quarter 2018. In response to the complexities and timing of issuance of the Tax Act, the SEC issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”). Management believes that it has made reasonable estimates of the impacts of the Tax Act in its 2017 consolidated financial statements. However, as the Company completes its analysis of the Tax Act, collects further data and reviews additional information and guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, the provisional amounts included in the 2017 financial statements may be subject to adjustment. Per the guidance in SAB 118, adjustments to the provisional amounts recorded by the Company in 2017 that are identified within a subsequent period of up to one year from the enactment date will be included as an adjustment in the period the amounts are determined. Income tax expense for the three months ended March 31, 2018, did not reflect any adjustment to the previously recognized provisional amounts under the Tax Act as discussed above. Except as provided for under the Transition Tax, no additional provision has been recorded related to the unremitted earnings of foreign subsidiaries. In accordance with SAB 118, the Company will continue to evaluate the impact of the Tax Act on its assertion that these earnings will be indefinitely reinvested. As noted above, the E&P for all foreign subsidiaries was included in the calculation of the provisional Transition Tax, and thus, should there be a repatriation of earnings from any foreign subsidiaries in future periods, the Company would be subject to only foreign withholding tax. The Company’s effective tax rate was 25.3% for the three months ended March 31, 2018 compared to 42.2% for the three months ended March 31, 2017. The primary reason for the decrease in the effective rate was due to the enactment of the Tax Act in December 2017, which reduced the U.S. federal corporate rate from 35% to 21%, effective January 1, 2018. The effective income tax rate for both periods was different than the Company’s statutory rate, primarily due to state taxes and non-deductible expenses. The total amount of gross unrecognized tax benefits that would reduce the Company’s effective tax rate was $0.4 million at March 31, 2018 and December 31, 2017, respectively. The Company and its subsidiaries file U.S. Federal, state and local, and non-U.S. income tax returns. As of March 31, 2018, the Company is no longer subject to U.S. Federal examination by tax authorities for tax years before 2014. The Company is subject to state and local examinations for tax years of 2013 through 2017. In addition, the Company is subject to non-U.S. income tax examinations for tax years of 2013 through 2017.

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the “Tax Act”).
