Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the "Tax Act") was enacted into law. The Tax Act provides for significant U.S. tax law changes and reduces the federal corporate statutory tax rate from 35% to 21% as of January 1, 2018. As a fiscal year-end taxpayer, our annual statutory federal corporate tax rate applicable to fiscal 2018 is a blended rate of 25.7%. Beginning in fiscal 2019, our annual statutory federal corporate tax rate is 21%. The Tax Act also requires companies to pay a one-time repatriation tax on certain unrepatriated earnings of foreign subsidiaries that were previously tax deferred ("transition tax"). We do not have any unrepatriated earnings for foreign subsidiaries and have not recorded a liability for the transition tax. The Tax Act initially repealed the Domestic Production Activities Deduction ("DPAD") and enacted the Deduction for Qualified Business Income of Pass-Thru Entities ("QBI Deduction"); however, the Consolidated Appropriations Act, 2018 (the "Appropriations Act") enacted into law on March 23, 2018, impacted these deductions. The Appropriations Act modifies the QBI Deduction under Section 199A of the Tax Act to reenact DPAD for agricultural and horticultural cooperatives as it existed prior to the enactment of the Tax Act, and it also modifies the QBI Deduction available to cooperative patrons as enacted by the Tax Act. As of August 31, 2018, the effects of the Tax Act were provisional in accordance with the SEC's Staff Accounting Bulletin No.118. No adjustments were recorded for the nine months ended May 31, 2019, associated with the remeasurement of deferred tax balances or the one-time transition tax, and in accordance with Staff Accounting Bulletin No.118, the amounts are no longer provisional.
