Income Taxes	9 Months Ended
May 31, 2020
Income Tax Disclosure [Abstract]
Income Taxes	Our effective tax rate for the three months ended May 31, 2020, was (38.4)%, compared to 11.1% for the three months ended May 31, 2019. Our effective tax rate for the nine months ended May 31, 2020, was (4.8)%, compared to 5.9% for the nine months ended May 31, 2019. The decreased effective tax rate reflects a tax benefit for the settlement of a U.S. federal audit resulting in additional tax credit carryovers, as well as the equity management assumptions used in fiscal 2020 and the associated impact on income taxes. It is reasonably possible that the amount of unrecognized tax benefits could significantly change within the next 12 months. We have ongoing federal, state and international income tax audits in various jurisdictions and are evaluating uncertain tax positions that may be challenged by local tax authorities and not fully sustained. These uncertain tax positions are reviewed on an ongoing basis and adjusted in light of facts and circumstances, including progression of tax audits, developments in case law and closing of statutes of limitation. The total amounts of unrecognized tax benefits that, if recognized, would affect the effective tax rate as of May 31, 2020, and August 31, 2019, are $111.1 million and $93.3 million, respectively.
