Income Taxes [Abstract]
Income Taxes	Note 14. 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 17.6% and 18.7% of income before income taxes for the three months ended February 29, 2020 and February 28, 2019, 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 during the quarter that are recognized in the provision for income tax, as well as an increase of taxable earnings from foreign operations which are taxed at lower tax rates. The provision for income taxes was 16.3% and 18.2% of income before income taxes for the six months ended February 29, 2020 and February 28, 2019, 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 during the second quarter that are recognized in the provision for income tax, an increase of taxable earnings from foreign operations which are taxed at lower tax rates, and a benefit from the release of liabilities associated with unrecognized tax benefits that resulted from the expiration of statutes. 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 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 2016 are no longer subject to examination. 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.

Note 14. 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 17.6% and 18.7% of income before income taxes for the three months ended February 29, 2020 and February 28, 2019, 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 during the quarter that are recognized in the provision for income tax, as well as an increase of taxable earnings from foreign operations which are taxed at lower tax rates.
