Income Taxes	9 Months Ended
May 31, 2018
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes During the third quarter of fiscal 2018, we recorded a $15.5 million impairment of income tax receivables related to Brazilian tax legislation enacted on May 30, 2018, which restricts our ability to utilize our Brazilian income tax credits. We also recorded current tax expense of $21.3 million related to the sale of certain assets, and $10.0 million stemming from CHS Inc.’s performance of guarantees to its Brazilian subsidiary for a fiscal 2017 loss. The third quarter of fiscal 2018 tax costs described above were more than offset by the deferred tax benefit from the revaluation of our U.S. net deferred tax liability as a result of the Tax Act recognized in the second quarter of fiscal 2018, which is the primary contributor to our tax benefit position for the nine months ended May 31, 2018, within the Consolidated Statements of Operations. On December 22, 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, the annual statutory federal corporate tax rate will be 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”), and creates new taxes on certain foreign sourced earnings. Foreign taxes historically have not had a material impact on our consolidated financial statements, and the foreign impacts of the Tax Act are discussed below. The Tax Act initially repealed the Domestic Production Activities Deduction ("DPAD") and enacted the Deduction for Qualified Business Income of Pass-Thru Entities ("QBI Deduction"); however,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 Sec. 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. All references to the Tax Act below include the modifications introduced by the Appropriations Act. On December 22, 2017, the SEC issued Staff Accounting Bulletin 118 ("SAB 118") which provides guidance on accounting for the effects of the Tax Act. SAB 118 provides for a measurement period of up to one year from the Tax Act’s enactment date for companies to complete their accounting under ASC 740, Income Taxes. In accordance with SAB 118, to the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in its financial statements. If a company cannot determine a provisional estimate to be included in its financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act. As of May 31, 2018, we have not finalized our work associated with the income tax effects of the enactment of the Tax Act; however, we have made a reasonable estimate of the effects on our existing deferred tax balances, and believe there will be no significant additional tax expense as a result of the one-time transition tax. Our income tax provision for the nine months ended May 31, 2018, reflects the current year impacts of the Tax Act on the estimated annual effective tax rate and a discrete provisional net benefit of $133.6 million from the revaluation of our U.S. net deferred tax liability resulting directly from the enactment of the Tax Act based on information available, prepared, or analyzed as of the date of this report. Deferred Tax Assets and Liabilities We remeasured our existing U.S. deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, of which the federal component is approximately 25.7% for reversals expected in fiscal 2018 and 21.0% thereafter. The calculation cannot be completed until all of the underlying timing differences as of August 31, 2018, are known and we are still analyzing certain aspects of the Tax Act and refining our calculations. As we complete our work and refine our calculations, any changes may give rise to new or additional deferred tax amounts. Specifically, we are now subject to the employee compensation deduction limitations under Internal Revenue Code Section 162(m), and we are evaluating whether our written binding employment contacts are exempted under the Tax Act’s Section 162(m) transition rule. Additional guidance from the IRS is necessary to ascertain the scope of the transition rule. Foreign Tax Effects To determine the amount of the transition tax, we must determine, in addition to other factors, the amount of post-1986 accumulated and current earnings and profits of our relevant subsidiaries as well as the amount of non-U.S. income taxes paid on such earnings. We are able to make a reasonable estimate of the transition tax and recorded no provisional tax liability. However, we continue to gather additional information and will refine the amount if necessary. We continue to review the anticipated impacts of global intangible low-taxed income ("GILTI"), including whether we should account for its tax effects as an in-period or deferred tax expense. Due to the complexity of the GILTI tax rules and the dependency upon future results of our global operations and our global structure, we are unable to make a reasonable estimate of this provision and consequently we haven't decided how to treat the deferred taxes associated with GILTI. Accordingly, we have not recorded any impact associated with GILTI in the tax rate during the three months ended May 31, 2018.
