Income Tax Disclosure [Abstract]
Income Taxes	NOTE 9 — INCOME TAXES The effective income tax rate of 25.9% for the three months ended February 29, 2020 compares to the effective income tax benefit rate of 224.7% for the three months ended February 28, 2019. The effective income tax rate for the three months ended February 29, 2020 reflects variances from the 21% statutory rate due primarily to the unfavorable impact of state and local income taxes and an increase in valuation allowances related to foreign net operating losses. Additionally, during the quarter, we recorded a net favorable discrete tax adjustment totaling $0.3 million. The net favorable discrete tax adjustment is comprised of a $10.9 million charge for an increase to our deferred income tax liability for withholding taxes on additional unremitted foreign earnings not considered permanently reinvested which was offset primarily by tax benefits associated with equity compensation, favorable adjustments related to foreign tax credits, and favorable adjustments related to the global intangible low-tax provisions, resulting from final Treasury Regulations issued during this quarter, and as reported on our 2019 U.S. federal income tax return. The effective income tax benefit rate of 224.7% for the three months ended February 28, 2019 reflects variances from the 21% statutory rate due primarily to the favorable impact of $12.7 million of net discrete tax benefits recorded during the quarter and the amplified impact of those tax benefits on the relatively low level of pre-tax earnings. The $12.7 million net discrete benefits recorded are primarily comprised of the net $8.1 million benefit resulting from completion of our SAB 118 accounting for the impact of the Tax Act, and the release of certain income tax reserves for uncertain tax positions. The effective income tax rate of 24.9% for the nine months ended February 29, 2020 compares to the effective income tax rate of 17.8% for the nine months ended February 28, 2019. The effective income tax rate for nine months ended February 29, 2020 reflects variances from the 21% statutory rate due primarily to the unfavorable impact of state and local income taxes, an increase in valuation allowances related to foreign net operating losses and tax benefits associated with equity compensation. The effective income tax rate of 17.8% for the nine months ended February 28, 2019 reflects variances from the 21% statutory rate due primarily to $16.5 million of net discrete tax benefits, which includes the $12.7 million net tax benefit described above with the remaining balance being recorded in the prior quarters of fiscal 2019. These discrete tax benefits were partially offset primarily by the unfavorable impact of state and local taxes and incremental valuation allowances associated with certain foreign net operating losses. Our deferred tax liability for unremitted foreign earnings was $29.7 million as of February 29, 2020, which represents our estimate of the foreign tax cost associated with the deemed remittance of $631.9 million of foreign earnings that are not considered to be permanently reinvested. We have not provided for foreign withholding or income taxes on the remaining foreign subsidiaries’ undistributed earnings because such earnings have been retained and reinvested by the subsidiaries as of February 29, 2020. Accordingly, no provision has been made for foreign withholding or income taxes, which may become payable if the remaining undistributed earnings of foreign subsidiaries were remitted to us as dividends.
