Income Tax Disclosure [Abstract]
Income Taxes	Note 14. Income Taxes The Company’s tax provision or benefit from income taxes for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period. The Company’s quarterly tax provision, and its quarterly estimate of its annual effective tax rate, are subject to significant variation due to several factors, including variability in accurately predicting its pre-tax income and loss and the mix of jurisdictions to which they relate, tax law developments and relative changes in permanent tax benefits or expenses. The Company’s effective tax rate for the three months ended September 30, 2018 and 2017 was 58.7% and (10.65%), respectively. For the three months ended September 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development, recognition of the U.S. global intangible low-taxed income ("GILTI") and an overall net tax benefit from certain tax reform measurement-period adjustments. For the three months ended September 30, 2017, the effective tax rate varied from the federal statutory rate of 35% primarily due to the level and mix of earnings among tax jurisdictions, the release of the valuation allowances recorded on the deferred tax assets in China and the recognition of employee share-based compensation in accordance with ASU No. 2016-09. The Company’s effective tax rate for the nine months ended September 30, 2018 and 2017 was (164.5%) and 9.15%, respectively. For the nine months ended September 30, 2018, the effective tax rate varied from the federal statutory rate of 21% primarily due to the level and mix of earnings among tax jurisdictions, share-based compensation, tax benefits related to research and development, recognition of the U.S. global intangible low-taxed income ("GILTI") and an overall net tax benefit from certain tax reform measurement-period adjustments. For the nine months ended September 30, 2017, the effective tax rate varied from the federal statutory rate of 35% primarily due to the level and mix of earnings among tax jurisdictions, the release of the valuation allowances recorded on the deferred tax assets in China and the recognition of employee share-based compensation in accordance with ASU No. 2016-09. On December 22, 2017, the President of the United Stated signed Public Law No. 115-97, commonly referred to as the Tax Cut and Jobs Act of 2017 (the “Tax Act”). The Tax Act makes significant changes to the U.S. tax code, which include, but are not limited to: a U.S federal corporate tax rate decrease from 35% to 21%, effective January 1, 2018; a shift to a modified territorial tax regime, which requires companies to pay a one-time transition tax on the mandatory deemed repatriation of the cumulative earnings of certain foreign subsidiaries as of December 31, 2017; a new provision designed to tax GILTI of foreign subsidiaries; a limitation of the deduction for net operating losses; elimination of net operating loss carrybacks; immediate deductions for depreciation expense for certain qualified property; additional limitations on the deductibility of executive compensation and limitations on the deductibility of interest. In December 2017, SEC issued Staff Accounting Bulletin No. 118 due to the Tax Act which allows the Company to record provisional amounts during a measurement period. As of September 30, 2018, the Company has completed the assessment of the corporate income tax impact expected to result from the Tax Act. The material impact of the Tax Act is described below. The deemed repatriation transition tax (the “Transition Tax”) is a tax on certain previously untaxed accumulated and current earnings and profits (E&P) of our foreign subsidiaries. The Company was able to reasonably estimate the Transition Tax and recorded a provisional Transition Tax obligation of $5.0 million, with a corresponding adjustment of $5.0 million to income tax expense for the year ended December 31, 2017. On the basis of revised E&P computations that were completed during the reporting period, the Company recognized an additional measurement-period adjustment of ($1.8) million to the Transition Tax obligation, with a corresponding adjustment of ($1.8) million to income tax expense during the nine months ended September 30, 2018. The effect of the measurement-period adjustment on the 2018 effective tax rate was approximately (106.3%). The Transition Tax, which has now been determined to be complete, resulted in recording a total Transition Tax obligation of $3.2 million, with a corresponding adjustment of $3.2 million to income tax expense. Additionally, the Company considers the earnings in its non-U.S. subsidiaries to be indefinitely reinvested and, accordingly, has recorded no deferred income taxes. While the transition tax resulted in the reduction of the excess of the amount for financial reporting over the tax basis in our foreign subsidiaries, an actual repatriation from its non-U.S. subsidiaries could be subject to additional foreign and U.S. state income taxes. Accordingly, the Company has not recorded any deferred taxes attributable to our investments in its foreign subsidiaries. The Company will record the tax effects of any change in its prior assertion should this assertion change and the Company is able to make a reasonable estimate, and disclose any unrecognized deferred tax liability for temporary differences related to our foreign investments, if practicable.
