Income Taxes [Abstract]
Income Taxes	Note 12. 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 28.3% and 28.5% of income before income taxes for the three months ended November 30, 2016 and 2015, respectively. The slight decrease in the effective income tax rate from period to period was primarily driven by a favorable mix of taxable earnings from foreign operations which are taxed at lower rates. 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 2014 are not subject to examination by the U.S. Internal Revenue Service. The Company was recently notified by the U.S. Internal Revenue Service of its plans to perform an income tax audit for the tax period ended August 31, 2015. The Company is also currently under audit in various state and local jurisdictions for fiscal years 2013 through 2015. Generally, for the majority of state and foreign jurisdictions where the Company does business, periods prior to fiscal year 2013 are no longer subject to examination. The Company has estimated that up to $0.2 million of 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.

Note 12. 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 28.3% and 28.5% of income before income taxes for the three months ended November 30, 2016 and 2015, respectively. The slight decrease in the effective income tax rate from period to period was primarily driven by a favorable mix of taxable earnings from foreign operations which are taxed at lower rates.

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 2014 are not subject to examination by the U.S. Internal Revenue Service.
