Income Taxes
Income Taxes	10. Income Taxes The Tax Act enacted in 2017, resulted in the U.S. Federal income tax rate being reduced from 35% to 21% effective January 1, 2018. During the measurement period, which is one year from the date of enactment, or the completion of all estimates made in connection with the Tax Act, companies are permitted to make additional income tax adjustments and revisions of estimates related to the Tax Act. During the quarter ended September 30, 2018, there were no material adjustments made to previously made estimates related to the Tax Act. We are currently in the process of completing our estimates for the transition tax related to our 2018 earnings, which will be finalized during the three months ended December 31, 2018. Due to the timing of the enactment and the complexity involved in applying the provisions of the Tax Act, in fiscal 2018, we recognized a provisional tax charge for the enactment of the Tax Act. In addition, the Tax Act subjects a U.S. corporation to tax on its GILTI (Global Intangible Low Income Tax), FDII (Foreign-Derived Tangible Income Taxes), and BEAT (Base Erosion Anti-abuse Tax). In the first quarter of fiscal 2019, we included an estimate of the impact of these taxes in our forecast effective tax rate. Interpretive guidance on the accounting for GILTI states that an entity can make an accounting policy election to either recognize deferred taxes for temporary basis differences expected to reverse as GILTI in future years or provide for the tax expense related to GILTI in the year the tax is incurred as a period expense only. Due to the complexity of the GILTI provisions, we are continuing to evaluate the effects of the GILTI provisions and have not yet determined our accounting policy. As of September 30, 2018, because we are still evaluating the GILTI provisions and our analysis of future taxable income that is subject to GILTI, we have included an estimate of GILTI and the FDII related to current-year operations only in our estimated annual effective tax rate and have not provided additional GILTI on deferred items. Due to the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of GAAP. As we collect and prepare necessary data and interpret the Tax Act and any additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service, and other standard-setting bodies, we may make adjustments to the provisional amounts. Those adjustments may materially affect our provision for income taxes and effective tax rate in the period in which the adjustments are made. The accounting for the tax effects of the Tax Act is expected to be completed in the quarter ended December 31, 2018. The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which we operate, and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, our tax expense can be impacted by changes in tax rates or laws, such as the Tax Act, the finalization of tax audits and reviews, and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions. During the three months ended September 30, 2018, we recognized a tax benefit for equity-based compensation of $1.5 million under ASU 2016-09 resulting in an effective tax rate of 13.9%. During the three months ended September 30, 2017, we recognized a $5.3 million valuation allowance related to deferred tax assets which was partially offset by a tax benefit for equity-based compensation of $4.6 million under ASU 2016-09 resulting in an effective tax rate of 32.9%. Excluding the impact of the discrete tax items noted above, our effective tax rate for the three months ended September 30, 2018 was 28.1% as compared to 28.3% in the prior-year period.
