Income Taxes [Abstract]
Income Taxes	Note 11. Income Taxes The computation of the annual expected effective tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected operating income (or loss) for the year, projections of the proportion of income (or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is acquired or additional information is obtained. The computation of the annual effective rate would include applicable modifications, which were projected for the year, such as certain book expenses not deductible for tax, tax credits and foreign deemed dividends. We recorded a tax expense of $9.6 million and $0.9 million for the three months ended March 31, 2019 and 2018, respectively. Included in tax expense for the three months ended March 31, 2019 was a valuation allowance in the amount of $9.8 million against our U.S. deferred tax asset based on management’s position that the Company has not met the more likely than not condition of realizing the deferred tax asset based on the existence of sufficient projected U.S. taxable income of the appropriate character to recognize the tax benefit. Without the valuation allowance, the net income tax benefit is approximately $0.2 million. For the three months ended March 31, 2018, our effective tax rate was 7.4%. The income tax expense and effective tax rate for the three months ended March 31, 2018 was significantly impacted by the U.S. Tax Cuts and Jobs Act of 2017 (the “2017 Tax Act”) including administrative guidance issued by the Internal Revenue Service on April 2, 2018. This guidance along with other updates resulted in a change to the calculation of the mandatory one-time tax on accumulated earnings of foreign subsidiaries in 2017 and a tax benefit of $2.1 million for the three months ended March 31, 2018 was recorded in tax expense with a corresponding reduction in the effective tax rate of 16.4%. Additionally, the effective tax rate for the three months ended March 31, 2019 and 2018 included a tax expense (benefit) of $0.3 million and $(0.3) million, respectively, for the tax effect of stock awards. The 2017 Tax Act was signed into law on December 22, 2017. The 2017 Tax Act significantly revised the U.S. corporate income tax by, among other things, lowering the statutory corporate tax rate from 35% to 21%, eliminating certain deductions, imposing a mandatory one-time tax on accumulated earnings of foreign subsidiaries as of 2017, introducing new tax regimes, and changing how foreign earnings are subject to U.S. tax. Our preliminary estimate of the 2017 Tax Act and the remeasurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act, changes to certain estimates and the filing of our tax returns. U.S. Treasury regulations, administrative interpretations or court decisions interpreting the 2017 Tax Act may require further adjustments and changes in our estimates. Those adjustments may impact our provision for income taxes in the period in which the adjustments are made.

Note 11. Income Taxes

The computation of the annual expected effective tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected operating income (or loss) for the year, projections of the proportion of income (or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of recovering deferred tax assets generated in the current year. The accounting estimates used to compute the provision for income taxes may change as new events occur, more experience is acquired or additional information is obtained. The computation of the annual effective rate would include applicable modifications, which were projected for the year, such as certain book expenses not deductible for tax, tax credits and foreign deemed dividends.

We recorded a tax expense of $9.6 million and $0.9 million for the three months ended March 31, 2019 and 2018, respectively. Included in tax expense for the three months ended March 31, 2019 was a valuation allowance in the amount of $9.8 million against our U.S. deferred tax asset based on management’s position that the Company has not met the more likely than not condition of realizing the deferred tax asset based on the existence of sufficient projected U.S. taxable income of the appropriate character to recognize the tax benefit.
