Income Taxes	Note 13. 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, is 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 June 30, 2018 and 2017 was 22.2% and 14.9%, respectively. For the three months ended June 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, and recognition of the U.S. global intangible low-taxed income ("GILTI"). For the three months ended June 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 2016-09. The Company’s effective tax rate for the six months ended June 30, 2018 and 2017 was 11.4% and 15.2%, respectively.

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. The Company was able to reasonably estimate the transition tax and recorded an initial 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. As a result of new interpretive guidance issued by the Treasury and the IRS, the Company recognized an additional measurement-period adjustment of ($0.8 million), with a corresponding adjustment of $0.8 million to income tax benefit during the six months ended June 30, 2018.

The Company will continue to refine its estimates related to the impact of the Tax Act during the one year measurement period from December 22, 2017 allowed under Staff Accounting Bulletin 118 (“SAB 118”). Additionally, the Company previously considered the earnings in its non-U.S. subsidiaries to be indefinitely reinvested and, accordingly, recorded no deferred income taxes. The Company is currently analyzing its global working capital and cash requirements and the potential tax liabilities attributable to a repatriation, but the Company has yet to determine whether it plans to change its prior assertion and repatriate earnings. 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 in the period that it completes its analysis and are able to make a reasonable estimate, and disclose any unrecognized deferred tax liability for temporary differences related to our foreign investments, if practicable.
