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 30.2% and 28.0% of income before income taxes for the three months ended February 28, 2013 and February 29, 2012, respectively and 30.6% and 29.5% of income before income taxes for the six months ended February 28, 2013 and February 29, 2012, respectively. The increase in the effective income tax rate from period to period for both the three months and six months was primarily driven by the release of uncertain tax position reserves associated with expiring statutes in the second quarter of fiscal year 2012 that did not reoccur in the same time period of the current fiscal year. The total amount of unrecognized tax benefits, excluding associated interest and penalties, was $1.1 million as of February 28, 2013, of which $0.8 million would impact the effective tax rate if recognized. The gross liability for income taxes related to unrecognized tax benefits is included in other long-term liabilities in the Company’s condensed consolidated balance sheets. The total balance of accrued interest and penalties related to uncertain tax positions was $0.3 million as of February 28, 2013 and August 31, 2012. The Company recognizes interest and penalties related to uncertain tax positions as a component of income tax expense and the accrued interest and penalties are included in deferred and other long-term liabilities in the Company’s condensed consolidated balance sheets. There were no material interest or penalties included in income tax expense for each of the three and six months ended February 28, 2013 and February 29, 2012. 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 2009 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 2008 are no longer subject to examination. The Company has estimated that up to $0.3 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. Audit outcomes and the timing of settlements are subject to significant uncertainty.
