Income Taxes | Note 10 - Income Taxes Income taxes are estimated for each of the jurisdictions in which the Company operates. Deferred income taxes reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as the tax effect of carryforwards. Realization of net deferred tax assets is dependent on future taxable income. At March 31, 2018, the Company’s U.S. deferred tax assets are fully offset by a valuation allowance since the Company cannot conclude that it is more likely than not that these future benefits will be realized. At the end of each interim reporting period, the effective tax rate is aligned with expectations for the full year. This estimate is used to determine the income tax provision on a year-to-date basis and may change in subsequent interim periods. If necessary, the year-to-date tax benefit for interim period losses is limited to the amount that could be recognizable at the end of the fiscal year. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act. The 2017 Tax Act makes broad and complex changes to the U.S. tax code that affects the Company’s 2018 financial results, including, but not limited to, a reduction in the U.S. federal corporate income tax rate from 35 percent to 21 percent; current U.S. taxation of global intangible low-taxed income (“GILTI”) of non-U.S. operations; additional limitations on the deductibility of executive compensation; and limitations on the deductibility of interest. The Company recognized the income tax effects of the 2017 Tax Act in its 2017 financial statements in accordance with SAB 118, which provides SEC staff guidance for the application of ASC 740 in the reporting period in which the 2017 Tax Act was signed into law. As such, the Company’s 2017 financial results reflect the income tax effects of the 2017 Tax Act, including provisional amounts for specific income tax effects of the 2017 Tax Act for which the accounting under ASC 740 is incomplete but for which a reasonable estimate could be determined. The Company is still in the process of evaluating the impacts of the 2017 Tax Act and considers the amounts previously recorded to be provisional, except for the impact of the change in tax rate on the Company’s deferred tax assets and liabilities as of December 31, 2017, for which the accounting is complete. The Company has not adjusted these estimates during the three months ended March 31, 2018 and will complete its analysis and finalize the amounts within the measurement period as provided by SAB 118. Loss before income taxes and income tax benefit for the three months ended March 31, 2018 and 2017 were as follows:
|  | Three months ended March 31, |
|  | 2018 |  | 2017 |
Loss before income taxes |  | $ | (16,057 | ) | $ | (8,887 | )
Income tax benefit |  | $ | (230 | ) | $ | (10,527 | )
The Company’s tax benefit for the three months ended March 31, 2018 was $0.2 million compared to $10.5 million for the comparable prior period. The 2018 tax benefit included a $0.1 million tax expense relating to the Company’s domestic operations and a $0.3 million tax benefit relating to the Company’s non-U.S. operations, compared to 2017 when its benefit included $4.3 million related to domestic operations and $6.2 million related to non-U.S. operations. The current period domestic tax expense is primarily attributable to the tax amortization of indefinite-lived intangible assets that is not available to offset U.S. deferred tax assets. The current period non-U.S. tax benefit is primarily attributable to the amortization of intangible assets, offset by tax expense on non-U.S operation profits incurred during the period, as well as foreign withholding taxes on unremitted earnings as of March 31, 2018. The domestic tax benefit for the comparable period is primarily attributable to an income tax benefit for losses incurred during such period, as the deferred tax liability created by the issuance of the Convertible Senior Notes is treated as a source of income in fiscal 2017, offset by a deferred provision related to tax amortization on indefinite-lived intangible assets. The comparable period non-U.S. tax benefit is primarily attributable to the reversal of an uncertain tax position that was determined to be realizable in 2017.
