Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES For the three months ended June 30, 2018, we recorded income tax expense of $0.3 million compared with an income tax benefit of $0.9 million for the three months ended June 30, 2017. Our effective tax rate was 19.9% for the three months ended June 30, 2018 compared with (20.2)% in the prior year period. The change in our income tax expense (benefit) was primarily due to pretax income during the three months ended June 30, 2018 compared to a pretax loss during the three months ended June 30, 2017. For the six months ended June 30, 2018, we recorded income tax expense of $0.4 million compared with an income tax benefit of $1.4 million for the six months ended June 30, 2017. Our effective tax rate was 20.5% for the six months ended June 30, 2018 compared with (21.5)% in the prior year period. The change in our income tax expense (benefit) was primarily due to pretax income during the six months ended June 30, 2018 compared to a pretax loss during the six months ended June 30, 2017. On December 22, 2017, the United States enacted the U.S. Tax Cuts and Jobs Act (the “Tax Cuts Act”), resulting in significant modifications to existing tax law. We are following the guidance in SEC Staff Accounting Bulletin 118 (“SAB 118”), which provides additional clarification regarding the application of ASC Topic 740 in situations where a company does not have the necessary information available, prepared, or analyzed in reasonable detail to complete the accounting for certain income tax effects of the Tax Cuts Act for the reporting period in which the Tax Cuts Act was enacted. SAB 118 provides for a measurement period beginning in the reporting period that includes the Tax Cuts Act's December 2017 enactment date and ending when we have obtained, prepared, and analyzed the information needed in order to complete the accounting for such income tax effects, but in no circumstances will the measurement period extend beyond one year from the enactment date. Under the Tax Cuts Act, changes include lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory tax on accumulated earnings in foreign subsidiaries, introducing new tax regimes, and changing how foreign earnings are subject to United States taxation. The statutory corporate tax rate reduction is effective for tax years beginning on or after January 1, 2018. Based on our best estimate, we have calculated the impact of the Tax Cuts Act in our current tax provision in accordance with our understanding of the Tax Cuts Act and available guidance. The portion of the provisional amount that related to the transition tax on the mandatory deemed repatriation of foreign earnings was $17.4 million based on our best estimate and guidance available as of the date of this filing, which was recorded in the fourth quarter of 2017. The provisional amount related to the transition tax on the mandatory deemed repatriation of foreign earnings has not changed as of June 30, 2018 when compared to December 31, 2017. Additional work is necessary to finalize our analysis of historical foreign earnings. Upon gathering all necessary data, interpreting any additional guidance from tax authorities, and completing the analysis, our provisional amount will be adjusted in the measurement period allowable in accordance with SAB 118. Our provisional amount relating to the transition tax may materially differ upon completing the analysis compared to the amount accrued as of June 30, 2018. We expect our analysis to be completed when our 2017 United States tax return is filed in the fourth quarter of 2018. Additionally, the Tax Cuts Act included a new provision designed to impose a tax on global intangible low-taxed income (“GILTI”) of foreign subsidiaries but allows the possibility of using foreign tax credits to offset the tax liability, subject to some limitations. For the three and six months ended June 30, 2018, our income tax expense included an estimate of the current GILTI impact on our tax provision, which we currently estimate would result in a tax liability of approximately $1.6 million for the year ended December 31, 2018. Based on our current forecast of taxable income for the United States and foreign tax jurisdictions, the estimated $1.6 million GILTI tax liability would be fully offset by the utilization of foreign tax credits and have an immaterial impact on our income tax expense for the year ended December 31, 2018. Our amount relating to GILTI may materially differ if the geographical mix of taxable earnings or total taxable earnings change compared to the assumptions used in our forecast.
