Accounting Policies [Abstract]
Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies	Basis of Presentation and Significant Accounting Policies Basis of Presentation These unaudited condensed consolidated financial statements reflect, in the opinion of management, all normal recurring adjustments necessary for a fair statement of our financial position, results of operations and cash flows for the periods presented. The results of operations and cash flows for interim periods are not necessarily indicative of results for a full fiscal year because of the seasonal nature of our businesses, among other things. Our unaudited condensed consolidated financial statements and notes are presented as permitted by the requirements for Quarterly Reports on Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto for the year ended August 31, 2019, included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission ("SEC"). Certain captions within the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Operations and Condensed Consolidated Statements of Cash Flows have been combined within other captions as allowed by SEC financial statement reporting requirements under Regulation S-X. Prior year information has been revised to conform with the current presentation. The recent outbreak and pandemic of the novel coronavirus known as COVID-19 and other factors resulted in substantial reductions in demand and sharp price declines in certain industries in which we operate during the third quarter of fiscal 2020, particularly with respect to the production of renewable fuels and other energy products. Based on these deteriorated macroeconomic and industry conditions, management considered the impacts on each of our businesses and determined that we needed to perform interim impairment assessments of goodwill and asset groups, as of April 30, 2020, for a reporting unit within our Ag segment that operates in the renewable fuels industry. Recent third-party price outlooks, projections of future volumes, expenses and other cash flows and a discount rate reflective of the relative risk of the cash flows were used to estimate fair value. Management believes the assumptions utilized in the assessment are appropriate and reasonable for estimating fair value. The estimated fair value of the reporting unit exceeded the carrying amount by approximately 18%, and thus no impairment was recorded. Management will continue to monitor results and projected cash flows to assess whether any impairment may be necessary in the future. Significant Accounting Policies The following significant accounting policy was updated or changed since our Annual Report on Form 10-K for the year ended August 31, 2019. Leases As described in the "Recent Accounting Pronouncements" section, we adopted Accounting Standards Update ("ASU") No. 2016-02, Leases, as amended (collectively "Accounting Standards Codification ("ASC") Topic 842"), on September 1, 2019, using the modified retrospective approach. Our accounting policies and additional disclosures with respect to ASC Topic 842 are included in Note 14, Leases. Recent Accounting Pronouncements Except for the recent accounting pronouncements described below, other recent accounting pronouncements are not expected to have a material impact on our condensed consolidated financial statements. Adopted We adopted ASC Topic 842 as of September 1, 2019, using the modified retrospective approach. In addition, we used the additional optional transition method and package of practical expedients in the period of adoption without retrospective adjustment to previous periods presented, although we elected not to apply the hindsight practical expedient available under the standard. As a result of using the modified retrospective method, prior periods have not been restated, and a $33.7 million cumulative-effect adjustment was recorded to increase the opening balance of capital reserves as of the adoption date related to recognition of previously deferred gains associated with the sale-leaseback of our primary corporate office building located in Inver Grove Heights, Minnesota. Additionally, adoption of ASC Topic 842 resulted in the recognition of operating lease right-of-use assets and associated lease liabilities of $268.4 million and $267.0 million, respectively, as of September 1, 2019. Adoption of ASC Topic 842 did not have a material impact on our Condensed Consolidated Statements of Operations or Condensed Consolidated Statements of Cash Flows. Additional information and further disclosures related to our leases and lease-related financial statement amounts are included within Note 14, Leases. Not Yet Adopted In June 2016, the Financial Accounting Standards Board issued ASU No. 2016-13, Financial Instruments - Credit Losses ("ASC Topic 326"): Measurement of Credit Losses on Financial Instruments. The amendments in this ASU introduce a new approach, based on expected losses, to estimate credit losses on certain types of financial instruments. This ASU is intended to provide financial statement users with more decision-useful information about the expected credit losses associated with most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures. Entities are required to apply the provisions of this ASU as a cumulative-effect adjustment to capital reserves as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for us beginning September 1, 2020, for our fiscal year 2021 and for interim periods within that fiscal year. The impact of adoption will depend on the composition of our portfolio at the adoption date and we are currently finalizing our evaluation of the impact of adoption on our condensed consolidated financial statements through various data-gathering activities, development of a credit loss model and accounting policy election determinations.
