16. INCOME TAXES (Continued) The reconciliation of the income tax expense at the U.S. Federal statutory rate (21.0% in fiscal 2019, 24.5% in fiscal 2018 and 35.0% in fiscal 2017) to actual income tax expense is as follows (in thousands): On December 22, 2017, the Tax Act was enacted. The Tax Act contains significant changes to U.S. tax law, including lowering the U.S. corporate income tax rate to 21.0%, implementing a territorial tax system with a one-time transition tax assessment on previously tax-deferred foreign earnings and imposing new taxes on certain foreign-sourced income. We elected to pay the one-time transition tax over a period of up to eight years. In conjunction with the Tax Act, the SEC issued guidance under Staff Accounting Bulletin No. 118 (‘‘SAB 118’’) directing taxpayers to record the impact of the Tax Act as ‘‘provisional’’ when they do not have all the necessary information to complete the accounting under ASC 740. The guidance allowed for a measurement period of up to one year after the enactment date of the Tax Act to finalize the recording of the related tax impact. In accordance with SAB 118, we recorded provisional estimates to our consolidated financial statements in fiscal 2018 based on the Tax Act. During the first quarter of fiscal 2019, we further analyzed the income tax effects of the Tax Act and determined there were no material changes to the provisional amounts disclosed in our fiscal 2018 financial statements. Although our accounting for the effects of the Tax Act is complete under SAB 118, there may be future adjustments based on interpretations by the U.S. federal and state governments and regulatory organizations, legislative updates or new regulations, or changes in accounting standards for income taxes. The Tax Act also includes provisions for Global Intangible Low-Taxed Income (‘‘GILTI’’) wherein taxes on foreign income are imposed in excess of a deemed return on tangible assets of foreign corporations. In general, this income will effectively be taxed at a 10.5% tax rate reduced by any available current year foreign tax credits. This provision became effective for taxable years beginning after December 31, 2017, which was our fiscal 2019. We have elected to treat tax generated by the GILTI provisions as a period expense. The effective tax rate on income from continuing operations before income taxes for fiscal 2019 of 10.4% was lower than the U.S. federal tax rate of 21.0% primarily due to the tax benefit from losses of our German subsidiaries, which are subject to higher tax rates than U.S. tax rates, adjustments related to the Tax Act’s transition tax, the net excess tax benefits from restricted stock unit vesting, the benefit of federal research and development tax credits and our Singapore and South Korea tax exemptions. These amounts are partially offset by an accrual for foreign withholding taxes on certain current year foreign earnings not considered permanently reinvested, stock-based compensation not deductible for tax purposes and limitations on the deductibility of compensation under Internal Revenue Code Section 162(m).
