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.

Discrete benefits, primarily those related to excess tax benefits from settlements of stock-based equity awards, reduced the effective income tax rate to a level significantly below the anticipated annual effective tax rate for each period. Although these discrete benefits increased from period to period, they decreased as a percentage of pre-tax income due to significantly higher pre-tax income during the first quarter of fiscal year 2021 which resulted in a higher effective income tax rate from period to period. The Company is subject to taxation in the U.S. and in various state and foreign jurisdictions. The Company is currently under examination by various state taxing authorities.

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 15.7% and 14.7% of income before income taxes for the three months ended November 30, 2020 and 2019, respectively. Discrete benefits, primarily those related to excess tax benefits from settlements of stock-based equity awards, reduced the effective income tax rate to a level significantly below the anticipated annual effective tax rate for each period. Although these discrete benefits increased from period to period, they decreased as a percentage of pre-tax income due to significantly higher pre-tax income during the first quarter of fiscal year 2021 which resulted in a higher effective income tax rate from period to period.

The Company is subject to taxation in the U.S. and in various state and foreign jurisdictions. The Company is currently under examination by various state taxing authorities. Due to expired statutes, the Company’s federal income tax returns for years prior to fiscal year 2017 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. The Company is currently under audit in various state and foreign jurisdictions for fiscal years 2017 through 2019. Estimated unrecognized tax benefits related to income tax positions may be affected by the resolution of tax examinations or expiring statutes of limitation within the next twelve months were not significant. Audit outcomes and the timing of settlements are subject to significant uncertainty.
