Income Taxes	8. Income Taxes The provision for income tax was an expense of $14.8 million in the three months ended October 31, 2018 and a benefit of $1.3 million in the six months ended October 31, 2018. This reflects a 23.9% (expense) and a 17.4% (benefit) effective tax rate compared to the U.S. federal statutory rate of 21.0%. This difference from the statutory rate is primarily due to the tradename impairment charge and the excess tax benefit on vested stock-based awards, both of which were recorded as discrete during the three months ended July 31, 2018. The excess tax benefit is the amount by which the Company’s tax deduction for these awards, based on the fair market value of the awards on the date of vesting, exceeds the expense recorded in the Company’s financial statements over the awards’ vesting period. In accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), we did not record any adjustment in the quarter to the provisional tax expense on accumulated foreign earnings (the “Transition Tax”) recorded during the fiscal year ended April 30, 2018 after the enactment of the Tax Act. This provisional expense may be adjusted in subsequent periods based on additional guidance that may be issued by the U.S. Treasury Department, the Internal Revenue Service (“IRS”) and other standard-setting bodies. The Company will continue to appropriately analyze and, if necessary, adjust this amount within the measurement period provided under SAB 118, with the analysis to be completed no later than December 22, 2018. The Company also continues to evaluate the impact of the Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), the change to the IRC Section 162(m) limitation (the “Executive Compensation Limitation”) and IRC Section 163 (j) interest limitation (the “Interest Limitation”) provisions of the Tax Act which is complex and subject to continuing regulatory interpretation. In accordance with SAB 118, we recorded a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 for GILTI, FDII and the Executive Compensation Limitation. For BEAT and the Interest Limitation computations, we did not record a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 because we currently estimate that these provisions will not affect our tax expense in the current fiscal year. We will continue to refine our provisional estimates for the GILTI, FDII, BEAT, Executive Compensation Limitation and Interest Limitation computations as we gather additional information and receive additional guidance from standard-setting bodies. The Company is required to make an accounting policy election of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current period expense when incurred (the “period cost method”) or (2) factoring such amounts in the Company’s measurement of its deferred taxes (the “deferred method”). The Company’s accounting policy election with respect to the new GILTI rules will depend, in part, on analyzing its global income to determine whether it can reasonably estimate the tax impact. In accordance with SAB 118, the Company is continuing with its analysis and will finalize the election in the following quarter.

8. Income Taxes

The provision for income tax was an expense of $14.8 million in the three months ended October 31, 2018 and a benefit of $1.3 million in the six months ended October 31, 2018. This reflects a 23.9% (expense) and a 17.4% (benefit) effective tax rate compared to the U.S. federal statutory rate of 21.0%. This difference from the statutory rate is primarily due to the tradename impairment charge and the excess tax benefit on vested stock-based awards, both of which were recorded as discrete during the three months ended July 31, 2018. The excess tax benefit is the amount by which the Company’s tax deduction for these awards, based on the fair market value of the awards on the date of vesting, exceeds the expense recorded in the Company’s financial statements over the awards’ vesting period.

In accordance with Staff Accounting Bulletin No. 118 (“SAB 118”), we did not record any adjustment in the quarter to the provisional tax expense on accumulated foreign earnings (the “Transition Tax”) recorded during the fiscal year ended April 30, 2018 after the enactment of the Tax Act. This provisional expense may be adjusted in subsequent periods based on additional guidance that may be issued by the U.S. Treasury Department, the Internal Revenue Service (“IRS”) and other standard-setting bodies. The Company will continue to appropriately analyze and, if necessary, adjust this amount within the measurement period provided under SAB 118, with the analysis to be completed no later than December 22, 2018.

The Company also continues to evaluate the impact of the Global Intangible Low-Taxed Income (“GILTI”), Foreign Derived Intangible Income (“FDII”), Base Erosion and Anti-Abuse Tax (“BEAT”), the change to the IRC Section 162(m) limitation (the “Executive Compensation Limitation”) and IRC Section 163 (j) interest limitation (the “Interest Limitation”) provisions of the Tax Act which is complex and subject to continuing regulatory interpretation. In accordance with SAB 118, we recorded a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 for GILTI, FDII and the Executive Compensation Limitation. For BEAT and the Interest Limitation computations, we did not record a provisional estimate in our effective tax rate for the three and six months ended October 31, 2018 because we currently estimate that these provisions will not affect our tax expense in the current fiscal year. We will continue to refine our provisional estimates for the GILTI, FDII, BEAT, Executive Compensation Limitation and Interest Limitation computations as we gather additional information and receive additional guidance from standard-setting bodies.
