Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Our income tax provision for the third quarter of fiscal years 2017 and 2016 reflects our estimates of the effective tax rates expected to be applicable for the full fiscal years, adjusted for any discrete events which are recorded in the period they occur. The estimates are reevaluated each quarter based on our estimated tax expense for the full fiscal year. Our effective income tax rate was 44% in the first nine months of fiscal year 2017 compared to 36% in the same period last year. The increase in our effective tax rate in the nine months ended August 31, 2017 compared to the same period in the prior year is primarily because during the preparation of our condensed consolidated financial statements for the three months ended May 31, 2016, we identified an error in our prior year income tax provision in which income tax expense was overstated for the year ended November 30, 2015 by $2.7 million related to our tax treatment of an intercompany gain. We determined that the error was not material to the prior year financial statements. We also concluded that recording an out-of-period correction would not be material and therefore corrected this error by recording an out-of-period $2.7 million tax benefit in our interim financial statements for the period ended May 31, 2016. Our federal income tax returns have been examined or are closed by statute for all years prior to fiscal year 2015. Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2012. Tax authorities for certain non-U.S. jurisdictions are also examining returns, none of which are material to our consolidated balance sheets, cash flows or statements of income. With some exceptions, we are generally no longer subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal year 2012.
