Income Taxes	(8) Income Taxes The U.S. Tax Cuts and Jobs Act of 2017 (the “Tax Cuts and Jobs Act”) was enacted on December 22, 2017, and introduced significant changes to U.S. income tax law. Effective in 2018, the Tax Cuts and Jobs Act reduced the U.S. statutory corporate tax rate from 35% to 21% and created new taxes in the U.S. on income in certain foreign controlled corporations, which are referred to as the global intangible low-taxed income tax (“GILTI”), and imposed a new tax on certain related party payments under the base erosion anti-abuse tax (“BEAT”). The inclusion of income earned in controlled foreign corporations under the GILTI regime did not result in any incremental U.S. tax expense during the three and six months ended June 30, 2018 due to the impact of a U.S. tax loss in the current period. The Company does not expect to be subject to the BEAT tax in 2018. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Cuts and Jobs Act, the Company has made reasonable estimates of the effects and recorded provisional amounts in its 2017 results. As the Company collects and prepares necessary data and interprets the Tax Cuts and Jobs Act and any additional guidance issued by the U.S. Treasury Department, the IRS, and other standard-setting bodies, additional adjustments to the provisional amounts may be made. Information needed to adjust provisional amounts include the completion of all international 2017 income tax returns. These additional adjustments may materially impact the provision for income taxes and effective tax rate in the period in which the adjustments are made. We expect the final accounting for the tax effects of the Tax Cuts and Jobs Act to be completed in 2018. A tax benefit from an uncertain tax position may be recognized only if it is more-likely than not that the tax position will be sustained on examination by the taxing authorities. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. During the six months ended June 30, 2018, the Company realized a $1.9 million tax benefit related to the resolution of a multi-year contingency in the U.S. The Company maintained reserves for unrecognized tax benefits of $5.6 million at June 30, 2018 and $7.7 million at December 31, 2017. At June 30, 2018, $4.2 million of the unrecognized tax benefits was netted against fully reserved U.S. deferred tax assets. The Company had accrued interest expense related to tax reserves of $1.2 million and $1.6 million, net of related tax effects, at June 30, 2018 and December 31, 2017, respectively.
