Income Taxes [Abstract]
Income Taxes	‎ Note 13. Income Taxes The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter. The provision for income taxes was 15.0% and 17.6% of income before income taxes for the three months ended February 28, 2021 and February 29, 2020, respectively. The decrease in the effective income tax rate from period to period was primarily due to an increase in excess tax benefits from settlements of stock-based equity awards, as well as the release of liabilities related to uncertain tax positions due to the expiration of statutes during the second quarter of fiscal year 2021. The provision for income taxes was 15.4% and 16.3% of income before income taxes for the six months ended February 28, 2021 and February 29, 2020, respectively. The decrease in the effective income tax rate from period to period was primarily due to a benefit from the High Tax Exemption associated with Global Intangible Low Taxed Income during the first half of fiscal year 2021, as well as an increase in excess tax benefits from settlements of stock-based equity awards. The impact of these items on income tax expense percentages was partially offset by the effect of significantly higher pre-tax income for the six months ended February 28, 2021 when compared to the corresponding period in the prior fiscal year. The Company is subject to taxation in the U.S. and in various state and foreign jurisdictions. Due to expired statutes, the Company’s federal income tax returns for years prior to fiscal year 2018 are not subject to examination by the U.S. Internal Revenue Service. Generally, for the majority of state and foreign jurisdictions where the Company does business, periods prior to fiscal year 2017 are no longer subject to examination.

Note 13. Income Taxes

The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes. Certain significant or unusual items are separately recognized in the quarter in which they occur and can be a source of variability in the effective tax rates from quarter to quarter.

The provision for income taxes was 15.0% and 17.6% of income before income taxes for the three months ended February 28, 2021 and February 29, 2020, respectively. The decrease in the effective income tax rate from period to period was primarily due to an increase in excess tax benefits from settlements of stock-based equity awards, as well as the release of liabilities related to uncertain tax positions due to the expiration of statutes during the second quarter of fiscal year 2021.

The provision for income taxes was 15.4% and 16.3% of income before income taxes for the six months ended February 28, 2021 and February 29, 2020, respectively. The decrease in the effective income tax rate from period to period was primarily due to a benefit from the High Tax Exemption associated with Global Intangible Low Taxed Income during the first half of fiscal year 2021, as well as an increase in excess tax benefits from settlements of stock-based equity awards.

The Company is subject to taxation in the U.S. and in various state and foreign jurisdictions. Due to expired statutes, the Company’s federal income tax returns for years prior to fiscal year 2018 are not subject to examination by the U.S. Internal Revenue Service.
