Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Our income tax provision for the three months ended February 28, 2019 and February 28, 2018 reflects our estimate 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. The increase in our effective tax rate in the three months ended February 28, 2019 compared to the same period in the prior year is primarily due to a provisional tax benefit amount of $1.4 million recorded in the three months ended February 28, 2018 related to the re-measurement of our U.S. deferred tax balances due to the enactment of tax reform in the U.S. that lowered the federal corporate tax rate. Certain international provisions of the Tax Cuts and Jobs Act became effective for us in fiscal year 2019. The global intangible low-taxed income ("GILTI") provisions require us to include in our U.S. income tax base foreign subsidiary earnings in excess of an allowable return of the foreign subsidiary's tangible assets. We have forecasted that we will be subject to incremental U.S. tax resulting from GILTI inclusions in fiscal year 2019. 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 2013. Tax authorities for certain non-U.S. jurisdictions are also examining returns. With some exceptions, we are generally not subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal year 2013.
