Accounting Policies [Abstract]
Organization, Basis of Presentation and Significant Accounting Policies	Organization, Basis of Presentation and Significant Accounting Policies Organization CHS Inc. ("CHS", "the Company", "we", "us", "our") is the nation’s leading integrated agricultural cooperative. As a cooperative, CHS is owned by farmers and ranchers and their member cooperatives ("members") across the United States. We also have preferred stockholders that own shares of our various series of preferred stock, which are each listed on the Global Select Market of the Nasdaq Stock Market LLC ("Nasdaq"). See Note 10, Equities for more detailed information. We buy commodities from and provide products and services to individual agricultural producers, local cooperatives and other companies (including member and other non-member customers), both domestic and international. Those products and services include initial agricultural inputs such as fuels, farm supplies, crop nutrients and crop protection products; as well as agricultural outputs that include grains and oilseeds, grain and oilseed processing and food products, and ethanol production and marketing. A portion of our operations are conducted through equity investments and joint ventures whose operating results are not fully consolidated with our results; rather, a proportionate share of the income or loss from those entities is included as a component in our net income under the equity method of accounting. Basis of Presentation The consolidated financial statements include the accounts of CHS and all wholly-owned and majority-owned subsidiaries and limited liability companies. The effects of all significant intercompany transactions have been eliminated. As described in Note 2, Restatement of Previously Issued Consolidated Financial Statements the consolidated financial statements for the years ended August 31, 2017 and 2016, have been restated to reflect the correction of misstatements to the consolidated financial statements. We have also restated all amounts impacted within the Notes to the consolidated financial statements. Over the course of fiscal 2017, we incurred charges related to a trading partner of ours in Brazil, which entered into bankruptcy-like proceedings under Brazilian law; intangible and fixed asset impairment charges associated with certain assets meeting the criteria to be classified as held for sale; fixed asset impairment charges due to the cancellation of a capital project at one of our refineries; and bad debt/loan loss reserve charges relating to a single large producer borrower. Charges and impairments of this nature, as well as any recoveries related to amounts previously reserved, are included in the Consolidated Statements of Operations in the line item, "reserve and impairment charges (recoveries), net" for the twelve months ended August 31, 2018 , 2017 , and 2016 . The timing and amounts of these charges and impairments, and any recoveries were determined utilizing facts and circumstances that were present in the respective years in which the charges, impairments or recoveries were recorded. See additional information related to the reserves and impairment charges in Note 3, Receivables, Note 6 , Property, Plant and Equipment , and Note 7 , Other Assets . The notes to our consolidated financial statements refer to our Energy, Ag and Nitrogen Production reportable segments, as well as our Corporate and Other category, which represents an aggregation of individually immaterial operating segments. The Nitrogen Production reportable segment resulted from our investment in CF Industries Nitrogen, LLC ("CF Nitrogen") in February 2016. Our investment in Ventura Foods, LLC ("Ventura Foods") is no longer a significant operating segment and is now included in our Corporate and Other category. See Note 12, Segment Reporting for more information. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Due to the inherent uncertainty involved in making estimates, actual results could differ from those estimates. We evaluate our estimates and assumptions on an ongoing basis. Cash and Cash Equivalents Cash equivalents include short-term, highly liquid investments with original maturities of three months or less at the date of acquisition. The fair value of cash and cash equivalents approximates the carrying value due to the short-term nature of the instruments. Inventories Grain, processed grain, oilseed, processed oilseed and other minimally processed soy-based inventories are stated at net realizable value. These inventories are agricultural commodity inventories that are readily convertible to cash because of their commodity characteristics, widely available markets and international pricing mechanisms. Agricultural commodity inventories have quoted market prices in active markets, may be sold without significant further processing and have predictable and insignificant disposal costs. Changes in the net realizable value of merchandisable agricultural commodities inventories are recognized in earnings as a component of cost of goods sold. All other inventories are stated at the lower of cost or net realizable value. Costs for inventories produced or modified by us through a manufacturing process include fixed and variable production and raw material costs, and in-bound freight costs for raw materials. Costs for inventories purchased for resale include the cost of products and freight incurred to place the products at our points of sale. The costs of certain energy inventories (wholesale refined products, crude oil and asphalt) are determined on the last-in, first-out ("LIFO") method; all other inventories of non-grain products purchased for resale are valued on the first-in, first-out ("FIFO") and average cost methods. Derivative Financial Instruments and Hedging Activities We enter into various derivative instruments to manage our exposure to movements primarily associated with agricultural commodity prices and to a lesser degree, foreign currency exchange rates and interest rates. Except for certain interest rate swap contracts, which are accounted for as cash flow hedges or fair value hedges, our derivative instruments represent economic hedges of price risk for which hedge accounting under Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging , is not applied. Rather, the derivative instruments are recorded on our Consolidated Balance Sheets at fair value with changes in fair value being recorded directly to earnings, primarily within cost of goods sold in our Consolidated Statements of Operations. See Note 13, Derivative Financial Instruments and Hedging Activities and Note 14, Fair Value Measurements for additional information. Although we have certain netting arrangements for our exchange-traded futures and options contracts and certain over-the-counter ("OTC") contracts, we have elected to report our derivative instruments on a gross basis on our Consolidated Balance Sheets under ASC Topic 210-20, Balance Sheet - Offsetting . Margin and Related Deposits Many of our derivative contracts with futures and options brokers require us to make margin deposits of cash or other assets. Subsequent margin deposits may also be necessary when changes in commodity prices result in a loss on the contract value, to comply with applicable regulations. Our margin and related deposit assets are held by external brokers in segregated accounts to support the associated derivative contracts and may be used to fund or partially fund the settlement of those contracts as they expire. Similar to our derivative financial instruments, margin and related deposits are also reported on a gross basis. Supplier Advance Payments and Rebates Supplier advance payments are typically for periods less than 12 months and primarily include amounts paid for grain purchases from suppliers and amounts paid to crop nutrient suppliers to lock in future supply and pricing. We receive volume-based rebates from certain vendors during the year. These vendor rebates are accounted for in accordance with ASC 605, Revenue Recognition, based on the terms of the volume rebate program. For those rebates which meet the definition of a binding arrangement and are both probable and estimable, we estimate the amount of the rebate we will receive and accrue it as a reduction of the cost of inventory over the period in which the rebate is earned. Investments The equity method of accounting is used for joint ventures and other investments in which we are able to exercise significant influence over the entity’s operations, but do not have a controlling interest in the entity. Various factors are considered when assessing significant influence, including our ownership interest, representation on the Board of Directors, voting rights, and the impact of commercial arrangements that may exist with the entity. Our equity in the income or loss of these equity method investments is recorded within equity (income) loss from investments in the Consolidated Statements of Operations. We account for our investment in CF Nitrogen, LLC using the hypothetical liquidation at book value method which is discussed further in Note 5 , Investments. The cost method of accounting is used for other investments in which we do not exercise significant influence. Investments in other cooperatives are stated at cost, plus patronage dividends received in the form of capital stock and other equities. Patronage dividends are recorded as a reduction to cost of goods sold at the time qualified written notices of allocation are received. Investments in other debt and equity securities are classified as available-for-sale financial instruments and are stated at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive loss on our Consolidated Balance Sheets. Investments in debt and equity instruments are carried at amounts that approximate fair values. Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on the straight-line method by charges to operations at rates based on the expected useful lives of individual or groups of assets (generally 15 to 20 years for land improvements; 20 to 40 years for buildings; 5 to 20 years for machinery and equipment; and 3 to 10 years for office equipment and other). Expenditures for maintenance and minor repairs and renewals are expensed, while the costs for major maintenance activities are capitalized and amortized on a straight-line basis over the period estimated to lapse until the next major maintenance activity occurs. We also capitalize and amortize eligible costs to acquire or develop internal-use software that are incurred during the application development stage. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the related accounts and resulting gains or losses are reflected in operations. Property, plant and equipment and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable. This evaluation of recoverability is based on various indicators, including the nature, future economic benefits and geographic locations of the assets, historical or future profitability measures, and other external market conditions. If these indicators suggest that the carrying amounts of an asset or asset group may not be recoverable, potential impairment is evaluated using undiscounted estimated future cash flows. Should the sum of the expected future net cash flows be less than the carrying value, an impairment loss would be recognized. An impairment loss would be measured at the amount by which the carrying value of the asset or asset group exceeds its fair value. We have asset retirement obligations with respect to certain of our refineries and other assets due to various legal obligations to clean and/or dispose of the component parts at the time they are retired. In most cases, these assets can be used for extended and indeterminate periods of time if they are properly maintained and/or upgraded. It is our practice and current intent to maintain refineries and related assets and to continue making improvements to those assets based on technological advances. As a result, we believe our refineries and related assets have indeterminate lives for purposes of estimating asset retirement obligations because dates or ranges of dates upon which we would retire a refinery and related assets cannot reasonably be estimated at this time. When a date or range of dates can reasonably be estimated for the retirement of any component part of a refinery or other asset, we estimate the cost of performing the retirement activities and record a liability for the fair value of that future cost. We have other assets that we may be obligated to dismantle at the end of corresponding lease terms subject to lessor discretion for which we have recorded asset retirement obligations. Based on our estimates of the timing, cost and probability of removal, these obligations are not material. Major Maintenance Activities Within our Energy segment, major maintenance activities (“turnarounds”) are performed at our Laurel, Montana and McPherson, Kansas refineries regularly. Turnarounds are the planned and required shutdowns of refinery processing units, which include the replacement or overhaul of equipment that have experienced decreased efficiency in resource conversion. Because turnarounds are performed to extend the life, increase the capacity, and/or improve the safety or efficiency of refinery processing assets, we follow the deferral method of accounting for turnarounds. Expenditures for turnarounds are capitalized (deferred) when incurred and amortized on a straight-line basis over a period of 2 to 4 years, which is the estimated time lapse between turnarounds. Should the estimated period between turnarounds change, we may be required to amortize the remaining cost of the turnaround over a shorter period, which would result in higher depreciation and amortization costs. Capitalized turnaround costs are included in other assets (long-term) on our Consolidated Balance Sheets and amortization expense related to the capitalized turnaround costs is included in cost of goods sold in our Consolidated Statements of Operations. The selection of the deferral method, as opposed to expensing the turnaround costs when incurred, results in deferring recognition of the turnaround expenditures. The deferral method also results in the classification of the related cash outflows as investing activities in our Consolidated Statements of Cash Flows, whereas expensing these costs as incurred would result in classifying the cash outflows as operating activities. Repair, maintenance and related labor costs are expensed as incurred and are included in operating cash flows. Goodwill and Other Intangible Assets Goodwill and other intangible assets are included in other assets (long-term) on our Consolidated Balance Sheets. Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of July 31, or more frequently if triggering events or other circumstances occur which could indicate impairment. Goodwill is tested for impairment at the reporting unit level, which has been determined to be our operating segments or one level below our operating segments in certain instances. Other intangible assets consist primarily of customer lists, trademarks and non-compete agreements. Intangible assets subject to amortization are expensed over their respective useful lives, which generally range from 2 to 30 years. We have no material intangible assets with indefinite useful lives. See Note 7, Other Assets for more information on goodwill and other intangible assets. Revenue Recognition We provide a wide variety of products and services, ranging from agricultural inputs such as fuels, farm supplies and crop nutrients, to agricultural outputs that include grain and oilseed, processed grains and oilseeds and food products, and ethanol production and marketing. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Sales are generally recognized upon transfer of title, which could occur either upon shipment to or receipt by the customer, depending upon the terms of the transaction. Shipping and handling amounts billed to a customer as part of a sales transaction are included in revenues, and the related costs are included in cost of goods sold. Environmental Expenditures We are subject to various federal, state, and local environmental laws and regulations. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Liabilities, including legal costs, related to remediation of contaminated properties are recognized when the related costs are considered probable and can be reasonably estimated. Estimates of environmental costs are based on current available facts, existing technology, undiscounted site-specific costs and currently enacted laws and regulations. Recoveries, if any, are recorded in the period in which recovery is received. Liabilities are monitored and adjusted as new facts or changes in law or technology occur. Income Taxes CHS is a nonexempt agricultural cooperative and files a consolidated federal income tax return within our tax return period. We are subject to tax on income from nonpatronage sources, non-qualified patronage distributions and undistributed patronage-sourced income. Income tax expense is primarily the current tax payable for the period and the change during the period in certain deferred tax assets and liabilities. Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for federal and state income tax purposes, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Reserves are recorded against unrecognized tax benefits when we believe that certain fully supportable tax return positions are likely to be challenged and that we may or may not prevail. If we determine that a tax position is more likely than not to be sustained upon audit, based on the technical merits of the position, we recognize the benefit by measuring the amount that is greater than 50% likely of being realized. We reevaluate the technical merits of our tax positions and recognize an uncertain tax benefit, or derecognize a previously recorded tax benefit, when there is (i) a completion of a tax audit, (ii) effective settlement of an issue, (iii) a change in applicable tax law including a tax case or legislative guidance, or (iv) the expiration of the applicable statute of limitations. Significant judgment is required in accounting for tax reserves. Recent Accounting Pronouncements Adopted In March 2018, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2018-05, Income Taxes (Topic 740) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU provides guidance on the income tax accounting implications of the Tax Cuts and Jobs Act of 2017 (the "Tax Act") and allows for entities to report provisional amounts for specific income tax effects of the Tax Act for which the accounting under ASC Topic 740 was not yet complete, but a reasonable estimate could be determined. A measurement period of one year is available to complete the accounting effects under ASC Topic 740 and revise any previous estimates reported. Any provisional amounts or subsequent adjustments included in an entity’s financial statements during the measurement period should be included in income from continuing operations as an adjustment to tax expense in the reporting period the amounts are determined. As of August 31, 2018, we have not finalized our work associated with the income tax effects of the enactment of the Tax Act, however, a reasonable estimate was provisionally recorded as a net benefit of $155.2 million from the revaluation of our U.S. net deferred tax liability that resulted from the reduced corporate tax rate and CHS being subject to the employee compensation deduction limitations imposed by Internal Revenue Code Section 162(m). In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220). Under existing U.S. GAAP, the effects of changes in tax rates and laws on deferred tax balances are recorded as a component of income tax expense in the period in which the law was enacted. When deferred tax balances related to items originally recorded in accumulated other comprehensive income are adjusted, certain tax effects become stranded in accumulated other comprehensive income. The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this ASU also require certain disclosures about stranded tax effects. This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. Early adoption in any period is permitted. The Company’s provisional adjustments recorded to account for the impact of the Tax Act resulted in stranded tax effects. We elected to early adopt ASU No. 2018-02 during the fourth quarter of fiscal 2018. The adoption resulted in a reclassification from accumulated other comprehensive income to retained earnings in the amount of $27.0 million for stranded tax effects resulting from the Tax Act. In August 2017, the FASB issued ASU No. 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . This ASU is intended to improve the financial reporting of hedging relationships to better represent the economic results of an entity’s risk management activities in its financial statements and make certain improvements to simplify the application of the hedge accounting guidance. The amendments in this ASU will make more financial and nonfinancial hedging strategies eligible for hedge accounting, amend the presentation and disclosure requirements and change how entities assess effectiveness. Entities are required to apply this ASU's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. We elected to early adopt ASU No. 2017-12 during the fourth quarter of fiscal 2018. The adoption did not have a material impact on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory (Topic 740). This ASU is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory by requiring an entity to recognize the income tax consequences when a transfer occurs, instead of when an asset is sold to an outside party. This ASU is effective for periods beginning after December 15, 2017; however, early adoption of this ASU is permitted during the first interim period if an entity issues interim financial statements. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt ASU No. 2016-16 during the first quarter of fiscal 2018. The adoption did not have a material impact on our consolidated financial statements. Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans , which amends ASC 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General . This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year and (b) the effects of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. The new disclosures include the interest crediting rates for cash balance plans and an explanation of significant gains and losses related to changes in benefit obligations. This ASU is effective for us beginning September 1, 2021, for our fiscal year 2022 and for interim periods within that fiscal year, with early adoption permitted. The adoption of this amended guidance in not expected to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which amends ASC 820, Fair Value Measurement . This ASU modifies the disclosure requirements for fair value measurements by removing, modifying and adding certain disclosures. Specifically, the guidance removes the requirement to disclose the amount and reasons for any transfers between Level 1 and Level 2 of the fair value hierarchy and removes the requirement to disclose a description of the valuation processes used to value Level 3 fair value measurements. The guidance also requires additional disclosures surrounding Level 3 changes in unrealized gains/losses included in other comprehensive income as well the range and weighted average significant unobservable inputs calculation. This ASU is effective for us beginning September 1, 2020, for our fiscal year 2021 and for interim periods within that fiscal year. Early adoption is permitted. We elected to remove the disclosures permitted by ASU No. 2018-13 during the fourth quarter of fiscal 2018 but have not early adopted the new required additional disclosures, which is permitted by the guidance. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Costs and Net Postretirement Benefit Cost. This ASU changes the presentation of net periodic pension cost and net periodic postretirement benefit cost in the Consolidated Statements of Operations. This ASU provides that the service cost component should be included in the same income statement line item as other compensation costs arising from services rendered by the employees during the period. The other components of net periodic benefit cost should be presented in the Consolidated Statements of Operations separately outside of operating income if that subtotal is presented. Additionally, only service cost may be capitalized in assets. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted as of the beginning of an annual period for which interim financial statements have not been issued or made available for issuance. The guidance on the presentation of the components of net periodic benefit cost in the Consolidated Statement of Operations should be applied retrospectively and the guidance regarding the capitalization of the service cost component in assets should be applied prospectively. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) : Clarifying the Definition of a Business . The amendments within this ASU narrow the existing definition of a business and provide a more robust framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The definition of a business impacts various areas of accounting, including acquisitions, disposals and goodwill. Under the new guidance, fewer acquisitions are expected to be considered businesses. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted, and the guidance should be applied prospectively to transactions following the adoption date. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This ASU is intended to reduce diversity in practice by adding or clarifying guidance on classification and presentation of changes in restricted cash on the Consolidated Statements of Cash Flows. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted, including in an interim period. The amendments in this ASU should be applied retrospectively to all periods presented. The adoption of this amended guidance is not expected to have a material impact on our Consolidated Statements of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU is intended to reduce existing diversity in practice in how certain cash receipts and payments are presented and classified in the Consolidated Statements of Cash Flows. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. The adoption of this amended guidance is not expected to have a material impact on our Consolidated Statements of Cash Flows. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (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 this ASU’s provisions as a cumulative-effect adjustment to retained earnings 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. We are currently evaluating the impact the adoption will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840 - Leases . The amendments within this ASU, as well as within additional clarifying ASUs issued by the FASB, introduce a lessee model requiring entities to recognize assets and liabilities for most leases, but continue recognizing the associated expenses in a manner similar to existing accounting guidance. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases , which amends ASU No. 2016-02, Leases . This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 a

Restatement of Previously Issue

Restatement of Previously Issued Consolidated Financial Statements	12 Months Ended

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	Restatement of Previously Issued Consolidated Financial Statements The consolidated financial statements for the years ended August 31, 2017 and 2016, have been restated to reflect the correction of misstatements. We have also restated all amounts impacted within the Notes to the consolidated financial statements. A description of the adjustments and their impact on the previously issued financial statements are included below. Descriptions of Restatement Adjustments Restatement Background During the preparation of our Annual Report on Form 10-K for the year ended August 31, 2018, we noted potentially excessive valuations in the net derivative asset valuations relating to certain rail freight contracts purchased in connection with our North American grain marketing operations. An investigation concluded that the rail freight misstatements included in our consolidated financial statements for the periods identified below were due to intentional misconduct by a former employee in our rail freight trading operations, as well as due to rail freight contracts and certain non-rail contracts not meeting the technical accounting requirements to qualify as a derivative financial instrument. The misconduct consisted of the former employee manipulating the mark-to-market valuation of rail cars that were the subject of rail freight purchase contracts and manipulating the quantity of rail cars included in the monthly mark-to-market valuation. In addition, the investigation revealed intentional misstatements were made by the former employee to our independent registered public accounting firm in connection with its audit of our consolidated financial statements for the fiscal year ended August 31, 2017. During the course of, and as a result of, the investigation, we terminated the former employee and have taken additional personnel actions. As a result of the misstatements, we have restated our consolidated financial statements as of and for the year ended August 31, 2017, and for the year ended August 31, 2016, in accordance with ASC 250, Accounting Changes and Error Corrections (the "Restated Financial Statements"). In addition to the adjustments related to freight derivatives and related misstatements, we also made adjustments related to certain intercompany balances and other historical misstatements unrelated to the freight derivatives and related misstatements. The restated interim financial information for the relevant unaudited interim financial statements for the quarterly periods ended November 30, 2017 and 2016, February 28, 2018 and 2017, May 31, 2018 and 2017, and August 31, 2017, is included in Note 18, Quarterly Financial Information (Unaudited) . The categories of restatement adjustments and their impact on previously reported consolidated financial statements are described below. (a) Freight Derivatives and Related Misstatements - Corrections for freight derivatives and related misstatements were driven by the misstatement of amounts associated with both the value and quantity of rail freight contracts, as well as due to rail freight contracts and certain non-rail freight contracts not meeting the technical accounting requirements to qualify as derivative financial instruments. In addition to the elimination of the underlying freight derivative assets and liabilities and related impacts on revenues and cost of goods sold, additional adjustments were recorded to account for prepaid freight capacity balances in relevant periods and the impact of a goodwill impairment charge recorded as of May 31, 2015, for goodwill held within our grain marketing reporting unit. Additional details related to the impact of the freight derivatives and related misstatements and their impact on each period are discussed in restatement reference (a). (b) Intercompany Misstatements - As a result of the work performed in relation to the freight misstatement, additional misstatements related to the incorrect elimination of intercompany balances were also identified and corrected within the consolidated financial statements. Certain of these intercompany misstatements resulted in a misstatement of various financial statement line items; however, the intercompany misstatements did not result in a material misstatement of income (loss) before income taxes or net income (loss). Additional details related to the impact of the intercompany misstatements and their impact on each period are discussed in restatement reference (b). (c) Other Misstatements - We made adjustments for other previously identified misstatements unrelated to the freight derivatives and related misstatements that were not material, individually or in the aggregate, to our consolidated financial statements. These other misstatements related primarily to certain misclassifications, adjustments to revenues and cost of goods sold, and adjustments to various income tax and indirect tax accrual accounts. Additional details related to the impact of the other misstatements and their impact on each period are discussed in restatement reference (c). Summary impact of restatement adjustments to previously reported financial information The following tables present the summary impacts of the restatement adjustments on our previously reported consolidated capital reserves and total equities at August 31, 2015, and income (loss) before income taxes and net income (loss) for the years ended August 31, 2017 and 2016: August 31, 2015 Capital Reserves Total Equities (Dollars in thousands) As previously reported $ 1,604,670 $ 7,669,411 Cumulative restatement adjustments (119,237 ) (117,972 ) As restated $ 1,485,433 $ 7,551,439 For the Years Ended August 31, 2017 2016 (Dollars in thousands) Income (loss) before income taxes - As previously reported $ (54,852 ) $ 419,878 Restatement adjustments (55,314 ) (17,753 ) Income (loss) before income taxes - As restated $ (110,166 ) $ 402,125 Net income (loss) - As previously reported $ 127,223 $ 423,969 Restatement adjustments (56,265 ) (40,943 ) Net income (loss) - As restated $ 70,958 $ 383,026 Reclassifications Amounts previously included within (gain) loss on investments were reclassified into other (income) loss to conform to the current year presentation. This reclassification had no impact on our previously reported net income, cash flows or shareholders' equity and represents a reclassification of $4.6 million and $9.3 million for the periods ended August 31, 2017, and August 31, 2016, respectively. Consolidated financial statement adjustment tables The following tables present the restatement adjustments to previously issued consolidated financial statements, including the previously reported Consolidated Balance Sheet as of August 31, 2017, and the Consolidated Statements of Operations, Comprehensive Income and Cash Flows for the years ended August 31, 2017, and 2016. The corrections of misstatements affecting fiscal years prior to fiscal 2017 are reflected as a cumulative adjustment to the balance of capital reserves and accumulated other comprehensive income as of August 31, 2015, on the Consolidated Statements of Changes in Shareholders’ Equity.

The reduction of total assets related primarily to the elimination of $156.0 million of long-term derivative assets, an approximate $16.0 million reduction of goodwill which was triggered by the lower earnings associated with this restatement with the impairment charge recorded during fiscal 2015 and the elimination of $12.9 million of current derivative assets that had been recorded as assets on the Consolidated Balance Sheet. The decreases of total assets were partially offset by related adjustments, including an $8.9 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $1.5 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to an $18.0 million reduction of current derivative liabilities and a $21.1 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities resulted from a $28.9 million increase of long-term deferred tax liabilities, which was partially offset by a $1.4 million reduction of long-term derivative liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) None Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of certain income tax adjustments on prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the impact of income tax adjustments resulted in a $19.3 million increase of total assets, an $89.1 million increase of current liabilities, a $32.1 million decrease of long-term liabilities and a $37.7 million decrease of total equities. The increase of total assets related primarily to a $49.2 million increase of inventory with a corresponding increase to accounts payable that resulted from a misclassification adjustment for certain items previously included within a contra-inventory account to accounts payable. The increased inventories were partially offset by a $24.1 million misclassification adjustment to decrease inventory and increase accounts receivable as a result of a timing difference related to the settlement of a single ocean vessel. The increase of total assets was partially offset by a $28.1 million decrease of prepaid income taxes associated with the correction of other misstatements identified during fiscal 2017 and other periods. The increase of current liabilities related primarily to the $49.2 million increase of accounts payable as a result of a misclassification adjustment for certain items previously included within a contra-inventory account to accounts payable and a $38.6 million increase of accrued expenses. The increase of accrued expenses primarily resulted from the recognition of a $24.9 million accrued income tax balance associated with the correction of other misstatements identified during fiscal 2017 and other periods. Additionally, $13.7 million of accrued expenses were recorded in relation to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. The decrease of long-term liabilities related to a $32.1 million decrease of long-term deferred tax liabilities that arose from the correction of other misstatements identified during fiscal 2017 and other periods. The $37.7 million decrease of total equities was primarily related to the $20.6 million net impact on income tax accounts and the recognition of $13.7 million of additional accrued expenses due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018.

These adjustments related primarily to a $38.1 million increase of cost of goods sold and a $9.2 million increase of income tax expense resulting from the tax effect of the freight derivatives and related misstatements. Intercompany misstatements (b) The correction of intercompany misstatements had no impact on income (loss) before income taxes or net income (loss); however, the correction resulted in a $35.7 million decrease of both revenues and cost of goods sold due to different practices of eliminating intercompany sales between CHS's businesses which existed in previous periods. Other misstatements (c) The correction of other misstatements resulted in a $17.2 million decrease of income before income taxes and a $9.0 million decrease of net income. The $17.2 million decrease of income before income taxes related to a $12.1 million increase of cost of goods sold due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018, a $2.6 million combined increase in cost of goods sold and marketing, general and administrative expenses for postretirement benefit plan activity that resulted from a timing difference associated with recording certain benefit plan expenses and a $2.5 million increase of costs of goods sold related to the valuation of crack spread derivatives. An income tax benefit of $8.2 million partially offset the decrease of income before income taxes and was recorded to adjust for the impact of other identified misstatements, as well as income tax items that had previously been identified and recorded as out of period adjustments in subsequent periods. Additionally, certain misclassification and offsetting adjustments were made between line items included in the Consolidated Statements of Operations primarily due to the application of differing accounting policies between businesses. These misclassification adjustments resulted in a $138.4 million increase of revenues, a $138.3 million increase of cost of goods sold, a $7.0 million increase of marketing, general and administrative expenses, a $2.2 million increase of loss on disposal of business and a $9.1 million increase of other income. For the year ended August 31, 2016 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $15.7 million reduction of income before income taxes and a $9.9 million reduction of net income. These adjustments related to a $15.7 million increase of cost of goods sold and a $5.8 million income tax benefit resulting from the tax effect of the freight derivatives and related misstatements. Intercompany misstatements (b) The correction of intercompany misstatements had no impact on income (loss) before income taxes or net income (loss); however, the correction resulted in a $57.5 million decrease of both revenues and cost of goods sold due to different practices of eliminating intercompany sales between CHS's businesses which existed in previous periods. Other misstatements The correction of other misstatements resulted in a $2.1 million decrease of income before income taxes and a $31.0 million decrease of net income. The $2.1 million decrease of income before income taxes related to a $1.7 million increase of cost of goods sold due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018 and a $0.4 million increase of costs of goods sold related to the valuation of crack spread derivatives. In addition to the decrease of income before income taxes, additional income tax expense of $29.0 million was recorded to adjust for the impact of other identified misstatements, as well as income tax items that had previously been identified and recorded as out of period adjustments in subsequent periods. Additionally, misclassification and offsetting adjustments were made between line items included in the Consolidated Statements of Operations primarily due to the application of differing accounting policies between businesses between businesses. These adjustments resulted in a $65.6 million increase of revenues, a $38.4 million increase of cost of goods sold and a $27.2 million increase of reserve and impairment charges (recoveries), net.

The impact of the adjustments to the Consolidated Balance Sheets as of August 31, 2017, and 2016, resulted in certain misclassification adjustments between line items in the Consolidated Statements of Cash Flows. As a result, two misclassification adjustments were made between operating and financing activities, including a $3.1 million reduction of notes payable resulted from a duplicative entry and the misclassification of a $6.0 million negative cash balance associated with a timing difference for the application of in-transit cash. Refer to descriptions of the adjustments and their impact on the Consolidated Balance Sheet in the Consolidated Balance Sheet section as of August 31, 2017, above. Additionally, an adjustment of $11.0 million was recorded to the opening cash balance, which related to a timing difference associated with the application of in-transit cash.

Receivables [Abstract]
Receivables	Receivables Receivables as of August 31, 2018 , and 2017 , are as follows: 2018 (As Restated) 2017 (Dollars in thousands) Trade accounts receivable $ 1,578,764 $ 1,258,644 CHS Capital short-term notes receivable 569,379 164,807 Deferred purchase price receivable — 202,947 Other 534,071 491,496 2,682,214 2,117,894 Less allowances and reserves 221,813 225,726 Total receivables $ 2,460,401 $ 1,892,168 Trade Accounts Trade accounts receivable are initially recorded at a selling price, which approximates fair value, upon the sale of goods or services to customers. Subsequently, trade accounts receivable are carried at net realizable value, which includes an allowance for estimated uncollectible amounts. We calculate this allowance based on our history of write-offs, level of past due accounts, and our relationships with and the economic status of our customers. Receivables from related parties are disclosed in Note 17, Related Party Transactions . During the third quarter of fiscal 2017, a trading partner of ours in Brazil entered bankruptcy-like proceedings under Brazilian law, resulting in a $98.7 million increase to our accounts receivable reserve. We also recorded a reserve of approximately $130.7 million related to supplier advance payments held by this trading partner, which is included in supplier advance payments in the Consolidated Balance Sheets. We initiated efforts to recover these losses during fiscal 2017 and we recorded a recovery of approximately $20.8 million during the fourth quarter of fiscal 2018 within reserve and impairment charges (recoveries), net in the Consolidated Statements of Operations. We continue to pursue additional recoveries in relation to these losses; however, additional recoveries are not estimable and have not been recorded as of the date of this Annual Report on Form 10-K. CHS Capital Notes Receivable CHS Capital, our wholly-owned subsidiary, has short-term notes receivable from commercial and producer borrowers. The short-term notes receivable have maturity terms of 12 months or less and are reported at their outstanding unpaid principal balances, adjusted for the allowance of loan losses, as CHS Capital has the intent and ability to hold the applicable loans for the foreseeable future or until maturity or pay-off. The carrying value of CHS Capital short-term notes receivable approximates fair value given the notes' short-term duration and the use of market pricing adjusted for risk. The notes receivable from commercial borrowers are collateralized by various combinations of mortgages, personal property, accounts and notes receivable, inventories and assignments of certain regional cooperative’s capital stock. These loans are primarily originated in the states of Minnesota, Wisconsin and North Dakota. CHS Capital also has loans receivable from producer borrowers which are collateralized by various combinations of growing crops, livestock, inventories, accounts receivable, personal property and supplemental mortgages and are originated in the same states as the commercial notes with the addition of Michigan. In addition to the short-term balances included in the table above, CHS Capital had long-term notes receivable, with durations of generally not more than 10 years , totaling $ 203.0 million and $ 17.0 million at August 31, 2018 , and 2017 , respectively. The long-term notes receivable are included in other assets on our Consolidated Balance Sheets. As of August 31, 2018 , and 2017 , the commercial notes represented 40% and 17% , respectively, and the producer notes represented 60% and 83% , respectively, of the total CHS Capital notes receivable. The increase in short-term and long-term notes receivable is the result of the activities described within the Sale of Receivables section below. CHS Capital has commitments to extend credit to customers if there are no violations of any contractually established conditions. As of August 31, 2018 , CHS Capital's customers have additional available credit of $ 706.3 million . Allowance for Loan Losses and Impairments CHS Capital maintains an allowance for loan losses which is the estimate of potential incurred losses inherent in the loans receivable portfolio. In accordance with FASB ASC 450-20, Accounting for Loss Contingencies, and ASC 310-10, Accounting by Creditors for Impairment of a Loan , the allowance for loan losses consists of general and specific components. The general component is based on historical loss experience and qualitative factors addressing operational risks and industry trends. The specific component relates to loans receivable that are classified as impaired. Additions to the allowance for loan losses are reflected within reserve and impairment charges (recoveries), net in the Consolidated Statements of Operations. The portion of loans receivable deemed uncollectible is charged off against the allowance. Recoveries of previously charged off amounts increase the allowance for loan losses. No significant amounts of CHS Capital notes were past due as of August 31, 2018 , or August 31, 2017 , and specific and general loan loss reserves related to CHS Capital notes were not material as of either date. Interest Income Interest income is recognized on the accrual basis using a method that computes simple interest on a daily basis. The accrual of interest on commercial loans receivable is discontinued at the time the receivable is 90 days past due unless the credit is well-collateralized and in process of collection. Past due status is based on contractual terms of the loan. Producer loans receivable are placed in non-accrual status based on estimates and analysis due to the annual debt service terms inherent to CHS Capital’s producer loans. In all cases, loans are placed in nonaccrual status or charged off at an earlier date if collection of principal or interest is considered doubtful. Troubled Debt Restructurings A restructuring of a loan constitutes a troubled debt restructuring, or restructured loan, if the creditor for economic reasons related to the debtor’s financial difficulties grants a concession to the debtor that it would otherwise not consider. Concessions vary by program and borrower. Concessions may include interest rate reductions, term extensions, payment deferrals, or the acceptance of additional collateral in lieu of payments. In limited circumstances, principal may be forgiven. When a restructured loan constitutes a troubled debt restructuring, CHS includes these loans within its impaired loans. During the third quarter of fiscal 2017 , CHS Capital concluded a transaction with a single producer borrower whereby CHS Capital obtained from the borrower title to approximately 14,000 acres of land and improvements that, prior to the transaction, was owned by the borrower and served as collateral for the outstanding loans to CHS Capital. The amount corresponding to the fair value of the land and improvements was credited against the notes receivable from this single producer borrower. As a result of this arrangement, all remaining outstanding notes receivable balances and corresponding reserves related to this single producer borrower were removed from the balance sheet of CHS Capital, with no incremental impact to the Consolidated Statements of Operations. During the first quarter of fiscal 2018, CHS Capital sold all rights to the outstanding notes receivable which had been previously removed from the balance sheet as they were deemed uncollectible. Through this sale, we realized a small recovery in the first quarter of fiscal year 2018. As of August 31, 2018, and 2017, CHS Capital had no other significant troubled debt restructurings and no third-party borrowers that accounted for more than 10% of the total CHS Capital notes receivable. Sale of Receivables Receivables Securitization Facility On June 28, 2018 , we amended an existing receivables and loans securitization facility (“Securitization Facility”) with certain unaffiliated financial institutions (the "Purchasers"). Under the Securitization Facility, we and certain of our subsidiaries sell trade accounts and notes receivable (the “Receivables”) to Cofina Funding, LLC (“Cofina”), a wholly-owned bankruptcy-remote indirect subsidiary of CHS. Cofina in turn transfers the purchased Receivables to the Purchasers. During the period from July 2017 through the amendment of the Securitization Facility in June 2018 , CHS accounted for Receivables sold under the Facility as a sale of financial assets pursuant to ASC 860, Transfers and Servicing, and the Receivables sold were derecognized from its Consolidated Balance Sheets. Under the terms of the amended Securitization Facility, the transfer of Receivables is accounted for as a secured borrowing. We use the proceeds from the sale of Receivables under the Securitization Facility for general corporate purposes. The Securitization Facility terminates on June 17, 2019 , but may be extended. The amount available under the Securitization Facility fluctuates over time based on the total amount of eligible Receivables generated during the normal course of business, with maximum availability of $700.0 million . Sales of Receivables by Cofina occur continuously and are settled with the Purchasers on a monthly basis. As of August 31, 2018 , and 2017 , the total availability under the Securitization Facility was $645.0 million and $618.0 million , respectively, of which all had been utilized. Prior to amending the Securitization Facility in June 2018, the proceeds from the sale of these Receivables were comprised of a combination of cash and a deferred purchase price (“DPP”) receivable. The DPP receivable was ultimately realized by CHS following the collection of the underlying Receivables sold to the Purchasers. At the time of the amendment to the Securitization Facility in June 2018, $1.0 billion of Receivables and $634.0 million of securitized debt were recognized and a DPP receivable of $386.9 million was removed from the Consolidated Balance Sheets. At the time of a previous amendment to the Securitization Facility in July 2017, $1.1 billion of Receivables and $554.0 million of securitized debt were removed from the Consolidated Balance Sheets and a DPP receivable of $580.5 million was recognized. These amounts have been reflected as non-cash transactions in the Consolidated Statements of Cash Flows and disclosed within Note 16, Supplemental Cash Flow and Other Information . Prior to its derecognition during June 2018, the fair value of the DPP receivable was determined by discounting the expected cash flows to be received based on unobservable inputs consisting of the face amount of the Receivables adjusted for anticipated credit losses. Refer to Note 14, Fair Value Measurements, for details related to the fair value measurement of the DPP receivable. The following table is a reconciliation of the beginning and ending balances of the DPP receivable, including the long-term portion included in other assets, for the years ended August 31, 2018 , and 2017 : 2018 2017 (Dollars in thousands) Balance - beginning of year $ 548,602 $ — Cash collections on DPP receivable (10,961 ) — Transfer of receivables (386,900 ) 580,509 Monthly settlements, net (169,827 ) (31,907 ) Fair value adjustment 19,086 — Balance - end of year $ — $ 548,602 Loan Participations During fiscal 2018 CHS Capital sold $64.1 million of notes receivable to numerous counterparties under a master participation agreement. The sale resulted in the removal of the notes receivable from the Consolidated Balance Sheet. CHS Capital has no retained interests in the transferred notes receivable, other than collection and administrative services. The proceeds from the sale of the notes receivable have been included in investing activities in the Consolidated Statement of Cash Flows. Fees received related to the servicing of the notes receivables are recorded in other income in the Consolidated Statements of Operations. We consider the fees received adequate compensation for services rendered, and accordingly have recorded no servicing asset or liability. Other Receivables Other receivables are comprised of certain other amounts recorded in the normal course of business, including receivables related to value added taxes and pre-crop financing, primarily to Brazilian farmers, to finance a portion of supplier production costs. CHS does not bear any of the costs or operational risks associated with the related growing crops. The financing is largely collateralized by future crops and physical assets of the suppliers, carries a local market interest rate and settles when the farmer’s crop is harvested and sold.

Our significant equity method investments consist of CF Nitrogen, Ventura Foods, and Ardent Mills, LLC ("Ardent Mills"), which are summarized below. CF Nitrogen On February 1, 2016, we invested $2.8 billion in CF Nitrogen, commencing our strategic venture with CF Industries Holdings, Inc. The investment consists of an approximate 10% membership interest (based on product tons) in CF Nitrogen. We also entered into an 80 -year supply agreement that entitles us to purchase up to 1.1 million tons of granular urea and 580,000 tons of urea ammonium nitrate ("UAN") annually from CF Nitrogen for ratable delivery. Our purchases under the supply agreement are based on prevailing market prices and we receive semi-annual cash distributions (in January and July of each year) from CF Nitrogen via our membership interest. These distributions are based on actual volumes purchased from CF Nitrogen under the strategic venture and will have the effect of reducing our investment to zero over 80 years on a straight-line basis. We account for this investment using the hypothetical liquidation at book value method, recognizing our share of the earnings and losses of CF Nitrogen based upon our contractual claims on the entity's net assets pursuant to the liquidation provisions of CF Nitrogen's Limited Liability Company Agreement, adjusted for the semi-annual cash distributions. For the years ended August 31, 2018 , and 2017 , these amounts were $106.9 million and $66.5 million , respectively, and are included as equity income from investments in our Nitrogen Production segment.

All long-lived assets, including property, plant and equipment, goodwill, investments in unconsolidated affiliates and other identifiable intangible assets, are evaluated for impairment in accordance with U.S. GAAP. Goodwill is evaluated for impairment annually as of July 31. All long-lived assets, including goodwill, are also evaluated for impairment whenever triggering events or other circumstances indicate that the carrying amount of an asset group or reporting unit may not be recoverable. No material impairments related to long-lived assets were recorded, and no goodwill impairments were identified as a result of CHS’s annual goodwill analyses performed as of July 31, 2018. During the year ended August 31, 2017, certain assets and liabilities associated with a disposal group in our Ag segment were classified as held for sale, including $5.5 million of goodwill allocated to the disposal group on a relative fair value basis. As a result of impairment tests performed over the disposal group, impairment charges of $78.8 million , which includes the allocated goodwill, were recorded in the reserve and impairment charges (recoveries), net line item in the Consolidated Statements of Operations for the year ended August 31, 2017.

Debt Disclosure [Abstract]
Notes Payable and Long-Term Debt	Notes Payable and Long-Term Debt Our notes payable and long-term debt are subject to various restrictive requirements for maintenance of minimum consolidated net worth and other financial ratios. We were in compliance with our debt covenants as of August 31, 2018 . Notes Payable Notes payable as of August 31, 2018 , and 2017 , consisted of the following: Weighted-average Interest Rate 2018 (As Restated) 2018 (As Restated) (Dollars in thousands) Notes payable 3.50% 2.40% $ 1,437,264 $ 1,695,423 CHS Capital notes payable 2.82% 1.90% 834,932 289,740 Total notes payable $ 2,272,196 $ 1,985,163 Our primary committed line of credit is a five -year, unsecured revolving credit facility with a syndication of domestic and international banks. We maintain a series of uncommitted bilateral facilities that are renewed annually. Amounts borrowed under these short-term credit facilities are used to fund our working capital. The following table summarizes our primary lines of credit as of August 31, 2018 , and 2017 : Primary Revolving Credit Facilities Fiscal Year of Maturity Total Capacity Borrowings Outstanding Interest Rates 2018 2018 2017 (Dollars in thousands) Committed Five-Year Unsecured Facility 2021 $ 3,000,000 $— $480,000 LIBOR or Base Rate +0.00% to 1.45% Uncommitted Bilateral Facilities 2019 515,000 515,000 350,000 LIBOR or Base Rate +0.00% to 1.20% In addition to our primary revolving lines of credit, we have a three -year $315.0 million committed revolving pre-export credit facility for CHS Agronegocio Industria e Comercio Ltda ("CHS Agronegocio"), our wholly-owned subsidiary, to provide financing for its working capital needs arising from its purchases and sales of grains, fertilizers and other agricultural products which expires in April 2020. As of August 31, 2018 , the outstanding balance under the facility was $181.1 million . As of August 31, 2018 , our wholly-owned subsidiaries, CHS Europe S.a.r.l. and CHS Agronegocio, had uncommitted lines of credit with $454.1 million outstanding. In addition, our other international subsidiaries had lines of credit with a total of $279.4 million outstanding as of August 31, 2018 , of which $40.5 million was collateralized. Miscellaneous short-term notes payable totaled $7.4 million as of August 31, 2018 . CHS Capital Notes Payable On June 28, 2018 , we amended our Securitization Facility with the Purchasers. Under the Securitization Facility, we and certain of our subsidiaries sell Receivables to Cofina, a wholly-owned bankruptcy-remote indirect subsidiary of CHS. Cofina in turn transfers the purchased Receivables to the Purchasers. During the period from July 2017 through the amendment of the Securitization Facility in June 2018 , CHS accounted for Receivables sold under the Securitization Facility as a sale of financial assets pursuant to ASC 860, Transfers and Servicing, and the Receivables sold were derecognized from its Consolidated Balance Sheets. Under the terms of the amended Securitization Facility, the transfer of Receivables is accounted for as a secured borrowing. We use the proceeds from the sale of Receivables under the Securitization Facility for general corporate purposes. The Securitization Facility terminates on June 17, 2019 , but may be extended. See Note 3, Receivables for additional information. CHS Capital has available credit under master participation agreements with several counterparties. Borrowings under these agreements are accounted for as secured borrowings and bear interest at variable rates ranging from 2.22% to 3.72% as of August 31, 2018. As of August 31, 2018, the total funding commitment under these agreements was $36.0 million , of which $6.3 million was borrowed. CHS Capital sells loan commitments it has originated to ProPartners Financial on a recourse basis. The total outstanding commitments under the program totaled $180.9 million as of August 31, 2018 , of which $98.3 million was borrowed under these commitments with an interest rate of 3.22% . CHS Capital borrows funds under short-term notes issued as part of a surplus funds program. Borrowings under this program are unsecured and bear interest at variable rates ranging from 0.10% to 1.40% as of August 31, 2018 , and are due upon demand. Borrowings under these notes totaled $69.3 million as of August 31, 2018 . Long-Term Debt During the year ended August 31, 2018 , we repaid approximately $208 million of long-term debt consisting of scheduled debt maturities and optional prepayments. There were no new material borrowings of long-term debt during fiscal 2018.

Changes in the fair value of the swaps are recorded each period with a corresponding adjustment to the carrying value of the debt. See Note 13, Derivative Financial Instruments and Hedging Activities for more information. (b) Borrowings are variable under the agreement and bear interest at a base rate (or a LIBO rate) plus an applicable margin. As of August 31, 2018 , the carrying value of our long-term debt approximated its fair value, which is estimated to be $1.8 billion based on quoted market prices of similar debt (a Level 2 fair value measurement based on the classification hierarchy of ASC Topic 820, Fair Value Measurement ). We have outstanding interest rate swaps designated as fair value hedges of select portions of our fixed-rate debt. During fiscal 2018, we recorded corresponding fair value adjustments of $18.7 million , which are included in the amounts in the table above. See Note 13, Derivative Financial Instruments and Hedging Activities for additional information. In September 2015, we entered into a 10 -year term loan with a syndication of banks. The agreement provides for committed term loans in an amount up to $600.0 million . As of August 31, 2018 , $236.0 million was outstanding under this agreement. In June 2016, we amended the 10 -year term loan so that $300.0 million of the $600.0 million loan balance possessed a revolving feature, whereby we were able to pay down and re-advance an amount up to the referenced $300.0 million . During fiscal 2017, we re-advanced $130.0 million under the revolving provision of the loan. As of August 31, 2018 , $130.0 million was outstanding under this agreement. Principal on the outstanding balances is payable in full in September 2025. Long-term debt outstanding as of August 31, 2018 , has aggregate maturities, excluding fair value adjustments and capital leases (see Note 6, Property, Plant and Equipment for a schedule of minimum future lease payments under capital leases), as follows: (Dollars in thousands) 2019 $ 162,846 2020 30,671 2021 182,472 2022 65 2023 282,065 Thereafter 1,260,570 Total $ 1,918,689 Interest expense for the years ended August 31, 2018 , 2017 , and 2016 , was $149.2 million , $171.2 million and $113.7 million , respectively, net of capitalized interest of $6.7 million , $6.9 million and $30.3 million , respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for (benefit from) income taxes for the years ended August 31, 2018 , 2017 , and 2016 is as follows: 2018 (As Restated) (As Restated) (Dollars in thousands) Current: Federal $ 15,576 $ 8,394 $ (14,536 ) State 7,041 (1,787 ) 2,427 Foreign 20,268 6,736 3,018 42,885 13,343 (9,091 ) Deferred: Federal (146,780 ) (173,184 ) 34,753 State (127 ) (13,244 ) (13,684 ) Foreign (54 ) (8,039 ) 7,121 (146,961 ) (194,467 ) 28,190 Total $ (104,076 ) $ (181,124 ) $ 19,099 The tax expense above for fiscal 2017 and 2016 are restatements of originally filed amounts to reflect necessary tax adjustments caused by restatements to pre-tax income for the relevant periods as well as to reflect certain tax only adjustments moved to or from other years. For fiscal 2017 and 2016, the adjustments to tax expense were $1.0 million and $23.2 million , respectively. In addition, the disclosures of deferred tax assets for fiscal 2017 discussed below similarly reflect restatements from originally filed amounts for changes in book income and tax only adjustments to or from previous years. The net deferred tax liability for fiscal 2017 reflects a total adjustment from originally filed for $3.7 million . All other disclosures reflect amounts after restatement. Domestic income before income taxes was $717.4 million , $158.5 million , and $473.0 million for the years ended August 31, 2018 , 2017 , and 2016 , respectively. Foreign income before income taxes was ($46.2) million , ($268.7) million , and ($70.9) million for the years ended August 31, 2018, 2017, and 2016, respectively. On December 22, 2017, the Tax Act was enacted into law. The Tax Act provides for significant U.S. tax law changes that reduced our 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 was 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 have not historically had a material impact on our consolidated financial statements. 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 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. As discussed in Note 1, Organization, Basis of Presentation and Significant Accounting Policies , the FASB issued ASU 2018-05 during March 2018, which allows for entities to report provisional amounts for specific income tax effects associated with the Tax Act for which the accounting is not complete, but a reasonable estimate can be determined. As of August 31, 2018, we have not finalized our work associated with the income tax effects of the enactment of the Tax Act; however, a reasonable estimate was provisionally recorded as a net benefit of $155.2 million from the revaluation of our U.S. net deferred tax liability that resulted from the reduced federal corporate tax rate and CHS being subject to the employee compensation deduction limitations imposed by Internal Revenue Code Section 162(m). We have provisionally estimated that we will not have a transition tax liability; however, we continue to gather additional information and will refine that estimate, if necessary. Additionally, we continue to review the anticipated impacts of global intangible low-taxed income ("GILTI"), including whether its tax effects should be accounted for 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 currently unable to make a reasonable estimate of this provision and have not recorded any impact associated with GILTI in the tax rate for the year ended August 31, 2018. Deferred taxes are comprised of basis differences related to investments, accrued liabilities and certain federal and state tax credits. Deferred tax assets and liabilities as of August 31, 2018 , and 2017 , are as follows: 2018 (As Restated) (Dollars in thousands) Deferred tax assets: Accrued expenses $ 138,417 $ 227,877 Postretirement health care and deferred compensation 41,797 82,682 Tax credit carryforwards 154,240 169,549 Loss carryforwards 104,519 156,615 Nonqualified equity 178,046 140,009 Major maintenance 5,484 13,011 Other 83,580 83,138 Deferred tax assets valuation reserve (230,373 ) (289,082 ) Total deferred tax assets 475,710 583,799 Deferred tax liabilities: Pension 19,397 32,150 Investments 98,608 130,816 Property, plant and equipment 513,238 709,313 Other 26,828 40,323 Total deferred tax liabilities 658,071 912,602 Net deferred tax liabilities $ 182,361 $ 328,803 We have total gross loss carry forwards of $531.1 million , of which $342.8 million will expire over periods ranging from fiscal 2019 to fiscal 2040. The remainder will carry forward indefinitely. Based on estimates of future taxable profits and losses in certain foreign tax jurisdictions, as well as consideration of other factors, we assessed whether a valuation allowance was necessary to reduce specific foreign loss carry forwards to amounts that we believe are more likely than not to be realized as of August 31, 2018 . If our estimates prove inaccurate, adjustments to the valuation allowances may be required in the future with gains or losses being charged to income in the period such determination is made. During fiscal 2018 , valuation allowances related to foreign operations decreased by $33.8 million due to net operating loss carry forwards and other timing differences. CHS McPherson Refinery Inc. ("CHS McPherson") (formerly known as National Cooperative Refinery Association) gross state tax credit carry forwards for income tax were approximately $121.6 million and $172.9 million as of August 31, 2018 , and 2017 , respectively. During the year ended August 31, 2018 , the valuation allowance for CHS McPherson decreased by $17.0 million , net of federal tax, due to a change in the amount of state tax credits that will be available for use and estimated to be utilized. The significant decrease in state tax credit carry forwards resulted from the CHS McPherson expansion project qualifying for an alternative Kansas state credit than the credit under which the project previously qualified. CHS McPherson's valuation allowance on Kansas state credits is necessary due to the limited amount of taxable income generated in Kansas by the combined group on an annual basis. Our foreign tax credit of $11.2 million was generated in fiscal 2018 and will expire in ten years. Our alternative minimum tax credit of $6.1 million will not expire. Our general business credits of $61.2 million , comprised primarily of low sulfur diesel credits, will begin to expire on August 31, 2027 and our state tax credits of $121.6 million will begin to expire on August 31, 2019. As of August 31, 2018 , and 2017 , net deferred tax assets of $0.4 million and $1.2 million were included in other assets, respectively. The reconciliation of the statutory federal income tax rates to the effective tax rates for the years ended August 31, 2018 , 2017 , and 2016 is as follows: 2018 (As Restated) (As Restated) Statutory federal income tax rate 25.7 % 35.0 % 35.0 % State and local income taxes, net of federal income tax benefit 0.7 12.1 0.3 Patronage earnings (13.6 ) 91.7 (21.2 ) Domestic production activities deduction (8.4 ) 30.5 (12.1 ) Export activities at rates other than the U.S. statutory rate 6.1 51.6 (3.0 ) U.S. tax reform (23.2 ) — — Intercompany transfer of business assets (6.1 ) — — Increase in unrecognized tax benefits 6.8 — — Valuation allowance (3.4 ) (77.1 ) 25.4 Tax credits 0.7 22.8 (14.1 ) Crack spread contingency — 4.8 (5.3 ) Other (0.8 ) (7.0 ) (0.3 ) Effective tax rate (15.5 )% 164.4 % 4.7 % The primary drivers of the fiscal 2018 income tax benefit are the recognition of deferred benefits from the revaluation of our net deferred tax liability resulting from the Tax Act, the intercompany transfer of a business on December 1, 2017 and a current tax benefit from retaining a significant portion of the DPAD, which were partially offset by deferred tax expense from an increase in our unrecognized tax benefit as descried below. The components of the income tax benefit disclosed as a percentage of income (loss) before income taxes in the reconciliation of the statutory federal income tax rate for the year ended August 31, 2017 , were magnified because our fiscal 2017 income tax benefit was unusually large in relation to our income (loss) before income taxes. The primary drivers of the fiscal 2017 income tax benefit were the recognition of deferred tax benefits related to the issuance of non-qualified equity certificates for fiscal 2013 and 2014, which is disclosed within ‘Patronage earnings’ and U.S. and Brazil deductions related to the Brazilian trading partner loss, which are disclosed within ‘Statutory federal income tax rate’ and ‘Export activities at rates other than the U.S. statutory rate’, respectively, as well as a current tax benefit from retaining a significant portion of the DPAD. A significant income tax expense within the fiscal 2017 income tax benefit is an increase in the valuation allowance against deferred tax assets generated in the Brazilian trading partner loss and Kansas state tax credits. We file income tax returns in the U.S. federal jurisdiction, as well as various state and foreign jurisdictions. Our uncertain tax positions are affected by the tax years that are under audit or remain subject to examination by the relevant taxing authorities. In addition to the current year, fiscal 2007 through 2017 remain subject to examination, at least for certain issues. We account for our income tax provisions in accordance with ASC Topic 740, Income Taxes , which prescribes a minimum threshold that a tax provision is required to meet before being recognized in our consolidated financial statements. This interpretation requires us to recognize in our consolidated financial statements tax positions determined more likely than not to be sustained upon examination, based on the technical merits of the position. A reconciliation of the gross beginning and ending amounts of unrecognized tax benefits for the periods presented follows: 2018 2017 2016 (Dollars in thousands) Balance at beginning of period $ 37,830 $ 37,105 $ 72,181 Additions attributable to current year tax positions 3,640 725 1,387 Additions attributable to prior year tax positions 49,665 — — Reductions attributable to prior year tax positions — — (36,463 ) Balance at end of period $ 91,135 $ 37,830 $ 37,105 During fiscal 2018 , adverse judicial opinions received by other taxpayers with similar filing positions resulted in an increase to our unrecognized tax benefits primarily for excise tax credits related to the blending and sale of renewable fuels deducted from income taxes. During fiscal 2017 , we increased our unrecognized tax benefits for excise tax credits related to the blending and sale of renewable fuels deducted for income taxes. During fiscal 2016 , we decreased our unrecognized tax benefits due to a settlement with the Internal Revenue Service and increased our unrecognized tax benefits for excise tax credits related to the blending and sale of renewable fuels deducted for income taxes. If we were to prevail on all positions taken in relation to uncertain tax positions, $83.3 million of the unrecognized tax benefits would ultimately benefit our effective tax rate. However, we do not believe it is reasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease within the next 12 months. We recognize interest and penalties related to unrecognized tax benefits in our provision for income taxes. We recognized $1.2 million for interest related to unrecognized tax benefits in our Consolidated Statement of Operations for the year ended August 31, 2018 , and a related $1.2 million interest payable on our Consolidated Balance Sheet as of August 31, 2018 . No interest or penalties were recognized in our Consolidated Statements of Operations for the years ended August 31, 2017 , and 2016 and no interest payable was recorded on our Consolidated Balance Sheet as of August 31, 2017 .

Equity [Abstract]
Equities	Equities In accordance with our bylaws and by action of the Board of Directors, annual net earnings from patronage sources are distributed to consenting patrons following the close of each fiscal year, and are based on amounts using financial statement earnings. The cash portion of the qualified patronage distribution, if any, is determined annually by the Board of Directors, with the balance issued in the form of qualified and/or non-qualified capital equity certificates. Total patronage distributions for fiscal 2018 are estimated to be $420.3 million , with the qualified cash portion estimated to be $75.0 million and non-qualified equity distributions of $345.3 million . No portion of annual net earnings for fiscal 2018 will be issued in the form of qualified capital equity certificates. Patronage distributions in fiscal 2017 were $128.8 million , with no cash portion. The actual patronage distributions and cash portion for fiscal 2016 , and 2015 were $ 257.5 million ( $103.9 million in cash), and $627.2 million ( $251.7 million in cash), respectively. Annual net earnings from patronage or other sources may be added to the unallocated capital reserve or, upon action by the Board of Directors, may be allocated to members in the form of nonpatronage equity certificates. The Board of Directors authorized, in accordance with our bylaws, that 10% of the earnings from patronage business for fiscal 2018 , 2017 , and 2016 be added to our capital reserves. Redemptions of outstanding equity are at the discretion of the Board of Directors. Redemptions of capital equity certificates approved by the Board of Directors are divided into two pools, one for non-individuals (primarily member cooperatives) who may participate in an annual redemption program for qualified equities held by them and another for individual members who are eligible for equity redemptions at age 70 or upon death. Beginning with fiscal 2017 patronage (for which distributions were made in fiscal 2018), CHS's redemption policy includes a redemption program for individuals similar to the one that was previously only available to non-individual members, subject to the CHS Board of Directors' overall discretion whether to redeem outstanding equity. In accordance with authorization from the Board of Directors, we expect total redemptions related to the year ended August 31, 2018 , that will be distributed in fiscal 2019 , to be approximately $75.0 million . This amount is classified as a current liability on our August 31, 2018 , Consolidated Balance Sheet. During the years ended August 31, 2018 , 2017 , and 2016 , we redeemed in cash, outstanding owners' equities in accordance with authorization from the Board of Directors, in the amounts of $ 8.8 million , $35.3 million and $ 23.9 million , respectively. In March 2017, we redeemed approximately $20.0 million of patrons' equities by issuing 695,390 shares of Class B Cumulative Redeemable Preferred Stock, Series 1 ("Class B Series 1 Preferred Stock"), with a total redemption value of $17.4 million , excluding accumulated dividends. Each share of Class B Series 1 Preferred Stock was issued in redemption of $28.74 of patrons' equities in the form of capital equity certificates. Additionally, in fiscal 2016, we redeemed approximately $76.8 million of patrons' equities by issuing 2,693,195 shares of Class B Series 1 Preferred Stock with a total redemption value of $67.3 million , excluding accumulated dividends. Each share of Class B Series 1 Preferred Stock was issued in redemption of $28.50 of patrons' equities in the form of capital equity certificates.

As of August 31, 2018 , we have no authorized but unissued shares of preferred stock. Accumulated Other Comprehensive Loss Changes in accumulated other comprehensive income (loss) by component, for the years ended August 31, 2018 , 2017 , and 2016 are as follows: Pension and Other Postretirement Benefits Unrealized Net Gain (Loss) on Available for Sale Investments Cash Flow Hedges Foreign Currency Translation Adjustment Total (Dollars in thousands) Balance as of August 31, 2015, net of tax (As previously reported) $ (171,729 ) $ 4,156 $ (5,324 ) $ (41,310 ) $ (214,207 ) Cumulative restatement adjustments — — — 1,370 1,370 Balance as of August 31, 2015, net of tax (As restated) (171,729 ) 4,156 (5,324 ) (39,940 ) (212,837 ) Other comprehensive income (loss), before tax: Amounts before reclassifications (10,512 ) 2,447 (11,353 ) (2,210 ) (21,628 ) Amounts reclassified out 20,998 — 5,071 469 26,538 Total other comprehensive income (loss), before tax 10,486 2,447 (6,282 ) (1,741 ) 4,910 Tax effect (3,903 ) (947 ) 2,410 (1,163 ) (3,603 ) Other comprehensive income (loss), net of tax 6,583 1,500 (3,872 ) (2,904 ) 1,307 Balance as of August 31, 2016, net of tax (As restated) (165,146 ) 5,656 (9,196 ) (42,844 ) (211,530 ) Other comprehensive income (loss), before tax: Amounts before reclassifications 25,216 7,117 1,892 (7,960 ) 26,265 Amounts reclassified out 26,174 — 1,742 15 27,931 Total other comprehensive income (loss), before tax 51,390 7,117 3,634 (7,945 ) 54,196 Tax effect (18,688 ) (2,732 ) (1,392 ) (214 ) (23,026 ) Other comprehensive income (loss), net of tax 32,702 4,385 2,242 (8,159 ) 31,170 Balance as of August 31, 2017, net of tax (As restated) (132,444 ) 10,041 (6,954 ) (51,003 ) (180,360 ) Other comprehensive income (loss), before tax: Amounts before reclassifications 7,633 21,078 1,031 (10,062 ) 19,680 Amounts reclassified out 21,804 (25,534 ) 1,704 (2,042 ) (4,068 ) Total other comprehensive income (loss), before tax 29,437 (4,456 ) 2,735 (12,104 ) 15,612 Tax effect (9,371 ) 1,308 (195 ) 83 (8,175 ) Other comprehensive income (loss), net of tax 20,066 (3,148 ) 2,540 (12,021 ) 7,437 Reclassification of tax effects to retained earnings (27,957 ) 1,968 (1,468 ) 465 (26,992 ) Balance as of August 31, 2018, net of tax $ (140,335 ) $ 8,861 $ (5,882 ) $ (62,559 ) $ (199,915 ) During fiscal 2018, we adopted ASU No. 2018-02, Reclassification of Certain Tax Effects From Accumulated Other Comprehensive Income . Under U.S. GAAP, the effects of tax law changes on deferred tax balances, including adjustments to deferred taxes originally recorded to accumulated other comprehensive income (loss), are recorded as a component of income tax expense. Adjusting deferred tax balances related to items originally recorded in accumulated other comprehensive income (loss) through tax expense resulted in a remaining accumulated other comprehensive income (loss) balance that was disproportionate to the amounts that would have been recorded through net income in future periods. The new guidance allowed us to reclassify $27.0 million of disproportionate (or stranded) amounts related to the Tax Act to capital reserves. Amounts reclassified from accumulated other comprehensive income (loss) were related to pension and other postretirement benefits, cash flow hedges, available for sale investments and foreign currency translation adjustments. Pension and other postretirement reclassifications include amortization of net actuarial loss, prior service credit and transition amounts and are recorded as cost of goods sold and marketing, general and administrative expenses (see Note 11, Benefit Plans for further information). Amortization related to gains or losses on cash flow hedges is recorded to interest expense. Gains or losses on the sale of available for sale investments are recorded to other income. Foreign currency translation reclassifications related to sales of businesses are recorded to gain on sale of business or reserve and impairment charges (recoveries), net. During fiscal 2016, interest rate swaps accounted for as cash flow hedges were terminated as the issuance of the underlying debt was no longer probable. As a result, a $3.7 million loss was reclassified from accumulated other comprehensive loss into net income. This pre-tax loss is included as a component of interest expense in our Consolidated Statement of Operations for the year ended August 31, 2016.

Retirement Benefits [Abstract]
Benefit Plans	Benefit Plans We have various pension and other defined benefit as well as defined contribution plans in which substantially all employees may participate. We also have non-qualified supplemental executive and Board retirement plans. Financial information on changes in benefit obligation, plan assets funded and balance sheet status as of August 31, 2018 , and 2017 , is as follows: Qualified Pension Benefits Non-Qualified Pension Benefits Other Benefits 2018 2017 2018 2017 2018 2017 (Dollars in thousands) Change in benefit obligation: Benefit obligation at beginning of period $ 806,174 $ 812,749 $ 25,599 $ 32,696 $ 31,836 $ 36,779 Service cost 39,677 42,149 548 1,206 943 1,160 Interest cost 24,007 22,999 711 843 908 930 Actuarial (gain) loss 3,146 (10,054 ) 205 (5,692 ) (623 ) (4,650 ) Assumption change (36,515 ) (17,750 ) (783 ) (655 ) (1,612 ) (775 ) Plan amendments 244 — — — — — Settlements — — (4,824 ) (2,131 ) — — Benefits paid (69,549 ) (43,919 ) (701 ) (668 ) (1,662 ) (1,608 ) Benefit obligation at end of period $ 767,184 $ 806,174 $ 20,755 $ 25,599 $ 29,790 $ 31,836 Change in plan assets: Fair value of plan assets at beginning of period $ 875,820 $ 883,265 $ — $ — $ — $ — Actual gain (loss) on plan assets 23,345 36,474 — — — — Company contributions — — 5,525 2,799 1,662 1,608 Settlements — — (4,824 ) (2,131 ) — — Benefits paid (69,549 ) (43,919 ) (701 ) (668 ) (1,662 ) (1,608 ) Fair value of plan assets at end of period $ 829,616 $ 875,820 $ — $ — $ — $ — Funded status at end of period $ 62,432 $ 69,646 $ (20,755 ) $ (25,599 ) $ (29,790 ) $ (31,836 ) Amounts recognized on balance sheet: Non-current assets $ 62,432 $ 70,019 $ — $ — $ — $ — Accrued benefit cost: Current liabilities — — (1,780 ) (2,270 ) (2,040 ) (2,140 ) Non-current liabilities — (373 ) (18,975 ) (23,329 ) (27,750 ) (29,696 ) Ending balance $ 62,432 $ 69,646 $ (20,755 ) $ (25,599 ) $ (29,790 ) $ (31,836 ) Amounts recognized in accumulated other comprehensive loss (pretax): Prior service cost (credit) $ 1,288 $ 2,481 $ (691 ) $ (660 ) $ (3,716 ) $ (4,281 ) Net (gain) loss 209,606 236,232 427 953 (17,875 ) (16,864 ) Ending balance $ 210,894 $ 238,713 $ (264 ) $ 293 $ (21,591 ) $ (21,145 ) The accumulated benefit obligation of the qualified pension plans was $ 736.2 million and $ 743.5 million at August 31, 2018 , and 2017 , respectively. The accumulated benefit obligation of the non-qualified pension plans was $ 18.6 million and $ 20.6 million at August 31, 2018 , and 2017 , respectively. Information for the pension plans with an accumulated benefit obligation in excess of plan assets is set forth below: For the Years Ended August 31, 2018 2017 (Dollars in thousands) Projected benefit obligation $ 20,755 $ 28,177 Accumulated benefit obligation 18,586 23,221 Fair value of plan assets — 2,203 A significant assumption for pension plan accounting is the discount rate. Historically, we have selected a discount rate each year (as of our fiscal year-end measurement date) for our plans based upon a high-quality corporate bond yield curve for which the cash flows from coupons and maturities match the year-by-year projected benefit cash flows for our pension plans. The corporate bond yield curve is comprised of high-quality fixed income debt instruments available at the measurement date. At August 31, 2016, we made the determination to use an individual spot-rate approach, discussed below. This alternative approach focuses on measuring the service cost and interest cost components of net periodic benefit cost by using individual spot rates derived from a high-quality corporate bond yield curve and matched with separate cash flows for each future year instead of a single weighted-average discount rate approach. As of August 31, 2016, we changed the method used to estimate the service and interest cost components of net periodic benefit cost for pension and other post-retirement benefits. This change in methodology has and is expected to continue to result in a decrease in the service and interest cost components for the pension and other post-retirement benefit costs. We historically estimated these service and interest cost components utilizing a single weighted-average discount rate derived from the yield curve used to measure the benefit obligation at the beginning of the period. Beginning in fiscal 2017, we elected to utilize a full-yield curve approach in the determination of these components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to the relevant projected cash flows. We elected to make this change to provide a more precise measurement of service and interest costs by improving the correlation between projected benefit cash flows to the corresponding spot yield curve rates. This change does not affect the measurement of our total benefit obligations at August 31, 2016, the net periodic cost recognized in fiscal 2016 or the ultimate benefit payment that must be made in the future. We have accounted for this change as a change in accounting estimate and, accordingly, have accounted for it on a prospective basis. Components of net periodic benefit costs for the years ended August 31, 2018 , 2017 , and 2016 are as follows: Qualified Pension Benefits Non-Qualified Pension Benefits Other Benefits 2018 2017 2016 2018 2017 2016 2018 2017 2016 (Dollars in thousands) Components of net periodic benefit costs: Service cost $ 39,677 $ 42,149 $ 37,533 $ 548 $ 1,206 $ 1,035 $ 943 $ 1,160 $ 1,412 Interest cost 24,007 22,999 30,773 711 843 1,406 908 930 1,709 Expected return on assets (48,159 ) (48,235 ) (48,055 ) — — — — — — Settlement of retiree obligations — — — (112 ) (30 ) — — — — Prior service cost (credit) amortization 1,437 1,540 1,606 30 19 228 (565 ) (565 ) (120 ) Actuarial loss (gain) amortization 18,073 22,869 19,016 61 546 692 (1,224 ) (798 ) (464 ) Net periodic benefit cost $ 35,035 $ 41,322 $ 40,873 $ 1,238 $ 2,584 $ 3,361 $ 62 $ 727 $ 2,537 Weighted-average assumptions to determine the net periodic benefit cost: Discount rate 3.80 % 3.60 % 4.20 % 3.53 % 3.28 % 4.20 % 3.56 % 3.30 % 4.20 % Expected return on plan assets 5.75 % 5.75 % 6.00 % N/A N/A N/A N/A N/A N/A Rate of compensation increase 5.08 % 5.60 % 4.90 % 5.08 % 5.60 % 4.90 % N/A N/A N/A Weighted-average assumptions to determine the benefit obligations: Discount rate 4.23 % 3.80 % 3.60 % 4.09 % 3.53 % 3.28 % 4.13 % 3.56 % 3.30 % Rate of compensation increase 5.14 % 5.08 % 5.60 % 5.14 % 5.08 % 5.60 % N/A N/A N/A Components of net periodic benefit costs and amounts recognized in other comprehensive income (loss) for the years ended August 31, 2018, 2017, and 2016 are as follows: Qualified Pension Benefits Non-Qualified Pension Benefits Other Benefits 2018 2017 2016 2018 2017 2016 2018 2017 2016 (Dollars in thousands) Other comprehensive income (loss) Prior service cost (credit) $ 244 $ — $ 411 $ — $ — $ (1,044 ) $ — $ — $ (4,495 ) Net actuarial loss (gain) (8,553 ) (16,044 ) 17,712 (578 ) (6,345 ) (655 ) (2,234 ) (5,427 ) (2,290 ) Amortization of actuarial loss (gain) (18,073 ) (22,869 ) (19,016 ) (61 ) (546 ) (692 ) 1,224 798 464 Amortization of prior service costs (credit) (1,437 ) (1,540 ) (1,606 ) (30 ) (19 ) (228 ) 565 565 120 Settlement of retiree obligations (a) — — — 112 30 — — — — Total recognized in other comprehensive income $ (27,819 ) $ (40,453 ) $ (2,499 ) $ (557 ) $ (6,880 ) $ (2,619 ) $ (445 ) $ (4,064 ) $ (6,201 ) (a) Reflects amounts reclassified from accumulated other comprehensive income (loss) to net earnings The estimated amortization in fiscal 2019 from accumulated other comprehensive loss into net periodic benefit cost is as follows: Qualified Pension Benefits Non-Qualified Pension Benefits Other Benefits (Dollars in thousands) Amortization of prior service cost (credit) $ 190 $ (75 ) $ (556 ) Amortization of net actuarial (gain) loss 12,266 2 (1,629 ) For measurement purposes, a 7.5% annual rate of increase in the per capita cost of covered health care benefits was assumed for the year ended August 31, 2018 . The rate was assumed to decrease gradually to 4.5% by 2027 and remain at that level thereafter. Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. A one-percentage point change in the assumed health care cost trend rates would have the following effects: 1% Increase 1% Decrease (Dollars in thousands) Effect on total of service and interest cost components $ 230 $ (200 ) Effect on postretirement benefit obligation 2,400 (2,100 ) We provide defined life insurance and health care benefits for certain retired employees and Board of Directors participants. The plan is contributory based on years of service and family status, with retiree contributions adjusted annually. We did not contribute to the qualified pension plans in fiscal 2018 . Based on the funded status of the qualified pension plans as of August 31, 2018 , we do not believe we will be required to contribute to these plans in fiscal 2019 , although we may voluntarily elect to do so. We expect to pay $ 3.8 million to participants of the non-qualified pension and postretirement benefit plans during fiscal 2019 . Our retiree benefit payments, which reflect expected future service, are anticipated to be paid as follows: Qualified Pension Benefits Non-Qualified Pension Benefits Other Benefits (Dollars in thousands) 2019 $ 66,528 $ 1,780 $ 2,040 2020 62,320 1,670 2,260 2021 61,279 1,750 2,400 2022 62,877 2,230 2,590 2023 64,573 1,840 2,720 2024-2028 328,313 9,270 12,690 We have trusts that hold the assets for the defined benefit plans.

Investment objectives for the plans' assets are as follows: • optimization of the long-term returns on plan assets at an acceptable level of risk; • maintenance of a broad diversification across asset classes and among investment managers; and • focus on long-term return objectives. Asset allocation targets promote optimal expected return and volatility characteristics given the long-term time horizon for fulfilling the obligations of the pension plans. Our pension plans' investment policy strategy is such that liabilities match assets. This is being accomplished through the asset portfolio mix by reducing volatility and de-risking the plans. The plans’ target allocation percentages range between 45% and 65% for fixed income securities, and range between 35% and 55% for equity securities. An annual analysis of the risk versus the return of the investment portfolio is conducted to justify the expected long-term rate of return assumption. We generally use long-term historical return information for the targeted asset mix identified in asset and liability studies. Adjustments are made to the expected long-term rate of return assumption, when deemed necessary, based upon revised expectations of future investment performance of the overall investment markets. The discount rate reflects the rate at which the associated benefits could be effectively settled as of the measurement date. In estimating this rate, we look at rates of return on fixed-income investments of similar duration to the liabilities in the plans that receive high, investment-grade ratings by recognized ratings agencies. The investment portfolio contains a diversified portfolio of investment categories, including domestic and international equities, fixed-income securities and real estate. Securities are also diversified in terms of domestic and international securities, short and long-term securities, growth and value equities, large and small cap stocks, as well as active and passive management styles. The committee believes that with prudent risk tolerance and asset diversification, the plans should be able to meet pension obligations in the future. Our pension plans’ recurring fair value measurements by asset category at August 31, 2018 , and 2017 , are presented in the tables below: 2018 Level 1 Level 2 Level 3 Total (Dollars in thousands) Cash and cash equivalents $ 7,424 $ — $ — $ 7,424 Equities: Mutual funds 692 — — 692 Common/collective trust at net asset value (1) — — — 216,962 Fixed income securities: Common/collective trust at net asset value (1) — — — 500,637 Partnership and joint venture interests measured at net asset value (1) — — — 101,954 Other assets measured at net asset value (1) — — — 1,947 Total $ 8,116 $ — $ — $ 829,616 2017 Level 1 Level 2 Level 3 Total (Dollars in thousands) Cash and cash equivalents $ 9,988 $ — $ — $ 9,988 Equities: Mutual funds 459 — — 459 Common/collective trust at net asset value (1) — — — 231,228 Fixed income securities: Common/collective trust at net asset value (1) — — — 535,185 Partnership and joint venture interests measured at net asset value (1) — — — 96,994 Other assets measured at net asset value (1) — — — 1,966 Total $ 10,447 $ — $ — $ 875,820 (1) In accordance with ASC Topic 820-10, Fair Value Measurements, certain assets that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been categorized in the fair value hierarchy. The fair value amounts presented in the tables above are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the statement of net assets. Definitions for valuation levels are found in Note 14, Fair Value Measurements . We use the following valuation methodologies for assets measured at fair value. Mutual funds: Valued at quoted market prices, which are based on the net asset value of shares held by the plan at year end. Mutual funds traded in active markets are classified within Level 1 of the fair value hierarchy. Mutual funds measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy in accordance with ASC Topic 820-10, Fair Value Measurement . Common/Collective Trusts: Common/collective trusts primarily consist of equity and fixed income funds and are valued using other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, credit risks, referenced indices, quoted prices in inactive markets, adjusted quoted prices in active markets, adjusted quoted prices on foreign equity securities that were adjusted in accordance with pricing procedures approved by the trust, etc.). Common/collective trust investments can be redeemed daily and without restriction. Redemption of the entire investment balance generally requires a 45- to 60-day notice period. The equity funds provide exposure to large, mid and small cap U.S. equities, international large and small cap equities and emerging market equities. The fixed income funds provide exposure to U.S., international and emerging market debt securities. Common/collective trusts measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy in accordance with ASC Topic 820-10, Fair Value Measurement . Partnership and joint venture interests: Valued at the net asset value of shares held by the plan at year end as a practical expedient for fair value. The net asset value is based on the fair value of the underlying assets owned by the trust, minus its liabilities then divided by the number of units outstanding. Redemptions of these interests generally require a 45- to 60-day notice period. Partnerships and joint venture interests measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy in accordance with ASC Topic 820-10, Fair Value Measurement. Other assets : Other assets primarily includes real estate funds and hedge funds held in the asset portfolio of our U.S. defined benefit pension plans. Other funds measured at fair value using the net asset value per share practical expedient have not been categorized in the fair value hierarchy in accordance with ASC Topic 820-10, Fair Value Measurement. We are one of approximately 400 employers that contribute to the Co-op Retirement Plan ("Co-op Plan"), which is a defined benefit plan constituting a “multiple employer plan” under the Internal Revenue Code of 1986, as amended, and a “multiemployer plan” under the accounting standards. The risks of participating in these multiemployer plans are different from single-employer plans in the following aspects: • Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; • If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; and • If we choose to stop participating in the multiemployer plan, we may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability. Our participation in the Co-op Plan for the years ended August 31, 2018 , 2017 , and 2016 is outlined in the table below: Contributions of CHS (Dollars in thousands) Plan Name EIN/Plan Number 2018 2017 2016 Surcharge Imposed Expiration Date of Collective Bargaining Agreement Co-op Retirement Plan 01-0689331 / 001 $ 1,662 $ 1,653 $ 1,862 N/A N/A Our contributions for the years stated above did not represent more than 5% of total contributions to the Co-op Plan as indicated in the Co-op Plan's most recently available annual report (Form 5500). Provisions of the Pension Protection Act of 2006 ("PPA") do not apply to the Co-op Plan because there is a special exemption for cooperative plans if the plan is maintained by more than one employer and at least 85% of the employers are rural cooperatives or cooperative organizations owned by agricultural producers. In the Co-op Plan, a “zone status” determination is not required, and therefore not determined. In addition, the accumulated benefit obligations and plan assets are not determined or allocated separately by individual employers. The most recent financial statements available in 2018 and 2017 are for the Co-op Plan's year-end at March 31, 2018 , and 2017 , respectively. In total, the Co-op Plan was at least 80% funded on those dates based on the total plan assets and accumulated benefit obligations. Because the provisions of the PPA do not apply to the Co-op Plan, funding improvement plans, and surcharges are not applicable. Future contribution requirements are determined each year as part of the actuarial valuation of the plan and may change as a result of plan experience. In addition to the contributions to the Co-op Plan listed above, total contributions to individually insignificant multi-employer pension plans were immaterial in fiscal 2018 , 2017 , and 2016 . We have other contributory defined contribution plans covering substantially all employees. Total contributions by us to these plans were $ 24.7 million , $ 19.9 million and $ 29.5 million , for the years ended August 31, 2018 , 2017 , and 2016 , respectively.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting We are an integrated agricultural enterprise, providing grain, foods and energy resources to businesses and consumers on a global basis. We provide a wide variety of products and services, from initial agricultural inputs such as fuels, farm supplies, crop nutrients and crop protection products, to agricultural outputs that include grains and oilseeds, grain and oilseed processing and food products, and the production and marketing of ethanol. We define our operating segments in accordance with ASC Topic 280, Segment Reporting , to reflect the manner in which our chief operating decision maker, our Chief Executive Officer, evaluates performance and allocates resources in managing the business. We have aggregated those operating segments into three reportable segments: Energy, Ag and Nitrogen Production. Our Energy segment produces and provides primarily for the wholesale distribution of petroleum products and transportation of those products. Our Ag segment purchases and further processes or resells grains and oilseeds originated by our country operations business, by our member cooperatives and by third parties; serves as a wholesaler and retailer of crop inputs; and produces and markets ethanol. Our Nitrogen Production segment consists solely of our equity method investment in CF Nitrogen, which was completed in February 2016 and which entitles us, pursuant to a supply agreement that we entered with CF Nitrogen, to purchase up to a specified annual quantity of granular urea and UAN annually from CF Nitrogen. The addition of the Nitrogen Production segment had no impact on historically reported segment results and balances as this segment came into existence in fiscal 2016. There were no changes to the composition of our Energy or Ag segments as a result of the addition of the Nitrogen Production segment. Corporate and Other primarily represents our non-consolidated wheat milling operations and packaged food joint ventures, as well as our business solutions operations, which primarily consists of commodities hedging, financial services related to crop production, and insurance which was disposed of in May 2018. Our investment in Ventura Foods is included in our Corporate and Other category. Corporate administrative expenses and interest are allocated to each business segment, and Corporate and Other, based on direct usage for services that can be tracked, such as information technology and legal, and other factors or considerations relevant to the costs incurred. Many of our business activities are highly seasonal and operating results vary throughout the year. For example, in our Ag segment, our crop nutrients and country operations businesses generally experience higher volumes and income during the spring planting season and in the fall, which corresponds to harvest. Our grain marketing operations are also subject to fluctuations in volume and earnings based on producer harvests, world grain prices and demand. Our Energy segment generally experiences higher volumes and profitability in certain operating areas, such as refined products, in the summer and early fall when gasoline and diesel fuel usage is highest and is subject to global supply and demand forces. Other energy products, such as propane, may experience higher volumes and profitability during the winter heating and crop drying seasons. Our revenues, assets and cash flows can be significantly affected by global market prices for commodities such as petroleum products, natural gas, grains, oilseeds, crop nutrients and flour. Changes in market prices for commodities that we purchase without a corresponding change in the selling prices of those products can affect revenues and operating earnings. Commodity prices are affected by a wide range of factors beyond our control, including the weather, crop damage due to disease or insects, drought, the availability and adequacy of supply, government regulations and policies, world events, and general political and economic conditions. While our revenues and operating results are derived from businesses and operations which are wholly-owned and majority-owned, a portion of our business operations are conducted through companies in which we hold ownership interests of 50% or less and do not control the operations. We account for these investments primarily using the equity method of accounting, wherein we record our proportionate share of income or loss reported by the entity as equity income from investments, without consolidating the revenues and expenses of the entity in our Consolidated Statements of Operations. In our Ag segment, this principally includes our 50% ownership in TEMCO. In our Nitrogen Production segment, this consists of our approximate 10% membership interest (based on product tons) in CF Nitrogen. In Corporate and Other, this principally includes our 50% ownership in Ventura Foods and our 12% ownership in Ardent Mills. See Note 5, Investments for more information related to CF Nitrogen, Ventura Foods and Ardent Mills. Reconciling amounts represent the elimination of revenues between segments. Such transactions are executed at market prices to more accurately evaluate the profitability of the individual business segments. Segment information for the years ended August 31, 2018 , 2017 , and 2016 is presented in the tables below.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments and Hedging Activities	Derivative Financial Instruments and Hedging Activities Our derivative instruments primarily consist of commodity and forward contracts and, to a minor degree, may include foreign currency and interest rate swap contracts. These contracts are economic hedges of price risk, but we do not apply hedge accounting under ASC Topic 815, Derivatives and Hedging , except with respect to certain interest rate swap contracts which are accounted for as cash flow hedges or fair value hedges as described below. Derivative instruments are recorded on our Consolidated Balance Sheets at fair value as described in Note 14, Fair Value Measurements . The following tables present the gross fair values of derivative assets, derivative liabilities, and margin deposits (cash collateral) recorded on our Consolidated Balance Sheets along with the related amounts permitted to be offset in accordance with U.S. GAAP. We have elected not to offset derivative assets and liabilities when we have the right of offset under ASC Topic 210-20, Balance Sheet - Offsetting; or when the instruments are subject to master netting arrangements under ASC Topic 815-10-45, Derivatives and Hedging - Overall .

Derivative assets and liabilities with maturities greater than 12 months are recorded in other assets and other liabilities, respectively, on the Consolidated Balance Sheets. The amount of long-term derivative assets, excluding derivatives accounted for as fair value hedges, recorded on the Consolidated Balance Sheet at August 31, 2018, and 2017, was $23.1 million and $ 30.9 million , respectively. The amount of long-term derivative liabilities, excluding derivatives accounted for as fair value hedges, recorded on the Consolidated Balance Sheet at August 31, 2018, and 2017, was $7.9 million and $12.3 million , respectively. Derivatives Not Designated as Hedging Instruments The majority of our derivative instruments have not been designated as hedging instruments. The following table sets forth the pretax gains (losses) on derivatives not accounted for as hedging instruments that have been included in our Consolidated Statements of Operations for the years ended August 31, 2018 , 2017 , and 2016 . Location of Gain (Loss) 2018 (As Restated) 2017 (As Restated) 2016 (Dollars in thousands) Commodity derivatives Cost of goods sold $ 162,321 $ 168,569 $ (67,014 ) Foreign exchange derivatives Cost of goods sold (26,010 ) (13,140 ) (10,904 ) Foreign exchange derivatives Marketing, general and administrative 596 (1,604 ) (97 ) Interest rate derivatives Interest expense (1 ) 8 (6,292 ) Embedded derivative Other income (loss) 3,061 30,533 — Total $ 139,967 $ 184,366 $ (84,307 ) Commodity Contracts: When we enter a commodity purchase or sales commitment, we are exposed to risks related to price changes and performance including delivery, quality, quantity and shipment period. If market prices decrease, we are exposed to risk of loss in the market value of inventory and purchase contracts with a fixed or partially fixed price. Conversely, we are exposed to risk of loss on our fixed or partially fixed price sales contracts if market prices increase. Our use of hedging reduces the exposure to price volatility by protecting against adverse short-term price movements, but it also limits the benefits of favorable short-term price movements. To reduce the price risk associated with fixed price commitments, we generally enter into commodity derivative contracts, to the extent practical, to achieve a net commodity position within the formal position limits we have established and deemed prudent for each commodity. These contracts are primarily transacted on regulated commodity futures exchanges but may also include over-the-counter derivative instruments when deemed appropriate. For commodities where there is no liquid derivative contract, risk is managed using forward sales contracts, other pricing arrangements and, to some extent, futures contracts in highly correlated commodities. These contracts are economic hedges of price risk, but are not designated as hedging instruments for accounting purposes. The contracts are recorded on our Consolidated Balance Sheets at fair values based on quotes listed on regulated commodity exchanges or the market prices of the underlying products listed on the exchanges, except that fertilizer and certain propane contracts are accounted for as normal purchase and normal sales transactions. Unrealized gains and losses on these contracts are recognized in cost of goods sold in our Consolidated Statements of Operations. When a futures position is established, initial margin must be deposited with the applicable exchange or broker. The amount of margin required varies by commodity and is set by the applicable exchange at its sole discretion. If the market price relative to a short futures position increases, an additional margin deposit would be required. Similarly, a margin deposit would be required if the market price relative to a long futures position decreases. Conversely, if the market price increases relative to a long futures position or decreases relative to a short futures position, margin deposits may be returned by the applicable exchange or broker. Our policy is to manage our commodity price risk exposure according to internal polices and in alignment with our tolerance for risk. Our profitability from operations is primarily derived from margins on products sold and grain merchandised, not from hedging transactions. At any one time, inventory and purchase contracts for delivery to us may be substantial. We have risk management policies that include established net position limits. These limits are defined for each commodity and business unit, and may include both trader and management limits as appropriate. The limits policy is managed within each individual business unit to ensure any limits overage is explained and exposures reduced, or a temporary limit increase is established if needed. The position limits are reviewed, at least annually, with senior leadership and the Board of Directors. We monitor current market conditions and may expand or reduce our net position limits in response to changes in those conditions. In addition, all purchase and sales contracts are subject to credit approvals and appropriate terms and conditions. The use of hedging instruments does not protect against nonperformance by counterparties to cash contracts. We evaluate counterparty exposure by reviewing contracts and adjusting the values to reflect potential nonperformance. Risk of nonperformance by counterparties includes the inability to perform because of a counterparty’s financial condition and the risk that the counterparty will refuse to perform on a contract during periods of price fluctuations where contract prices are significantly different than the current market prices. We manage these risks by entering into fixed price purchase and sales contracts with preapproved producers and by establishing appropriate limits for individual suppliers. Fixed price contracts are entered into with customers of acceptable creditworthiness, as internally evaluated. Regarding our use of derivatives, we primarily transact in exchange traded instruments or enter into over-the-counter derivatives that clear through a designated clearing organization, which limits our counterparty exposure relative to hedging activities. Historically, we have not experienced significant events of nonperformance on open contracts. Accordingly, we only adjust the estimated fair values of specifically identified contracts for nonperformance. Although we have established policies and procedures, we make no assurances that historical nonperformance experience will carry forward to future periods. As of August 31, 2018 , and 2017 , we had outstanding commodity futures and options contracts that were used as economic hedges, as well as fixed-price forward contracts related to physical purchases and sales of commodities. The table below presents the notional volumes for all outstanding commodity contracts accounted for as derivative instruments. 2018 (As Restated) 2017 Long Short Long Short (Units in thousands) Grain and oilseed - bushels 715,866 929,873 569,243 767,110 Energy products - barrels 17,011 8,329 15,072 18,252 Processed grain and oilseed - tons 1,064 2,875 299 2,347 Crop nutrients - tons 11 76 9 15 Ocean freight - metric tons 227 45 160 198 Natural gas - MMBtu 610 — 500 — Foreign Exchange Contracts We conduct a substantial portion of our business in U.S. dollars, but we are exposed to risks relating to foreign currency fluctuations primarily due to grain marketing transactions in South America, the Asia Pacific region, and Europe, and purchases of products from Canada. We use foreign currency derivative instruments to mitigate the impact of exchange rate fluctuations. Although CHS has some risk exposure relating to foreign currency transactions, a larger impact with exchange rate fluctuations is the ability of foreign buyers to purchase U.S. agricultural products and the competitiveness of U.S. agricultural products compared to the same products offered by alternative sources of world supply. The notional amounts of our foreign exchange derivative contracts were $988.8 million and $776.7 million as of August 31, 2018 , and August 31, 2017 , respectively. Embedded Derivative Asset Under the terms of our strategic investment in CF Nitrogen, if CF Industries' credit rating is reduced below certain levels by two of three specified credit ratings agencies, we are entitled to receive a non-refundable annual payment of $5.0 million from CF Industries. These payments will continue on an annual basis until the date that CF Industries' credit rating is upgraded to or above certain levels by two of the three specified credit ratings agencies or February 1, 2026, whichever is earlier. During the first quarter of fiscal 2017, CF Industries' credit rating was reduced below the specified levels and we recorded a gain of $29.1 million in other income (loss) in our Consolidated Statement of Operations and received a $5.0 million payment from CF Industries. A total gain of $30.5 million was recognized in relation to the embedded credit derivative during fiscal 2017. During fiscal 2018, we received a second $5.0 million payment from CF Industries. The fair value of the embedded derivative asset recorded on our Consolidated Balance Sheet as of August 31, 2018 , was equal to $23.6 million . The current and long-term portions of the embedded derivative asset are included in derivative assets and other assets on our Consolidated Balance Sheet, respectively. See Note 14, Fair Value Measurements for additional information regarding the valuation of the embedded derivative asset. Derivatives Designated as Cash Flow or Fair Value Hedging Strategies Fair Value Hedges As of August 31, 2018 , and 2017 , we had outstanding interest rate swaps with an aggregate notional amount of $495.0 million designated as fair value hedges of portions of our fixed-rate debt that is due between fiscal 2019 and fiscal 2025. Our objective in entering into these transactions is to offset changes in the fair value of the debt associated with the risk of variability in the three-month U.S. dollar LIBOR interest rate ("LIBOR"), in essence converting the fixed-rate debt to variable-rate debt. Under these interest rate swaps, we receive fixed-rate interest payments and make interest payments based on the three-month LIBOR. Offsetting changes in the fair values of both the swap instruments and the hedged debt are recorded contemporaneously each period and only create an impact to earnings to the extent that the hedge is ineffective. The following table presents the fair value of our derivative interest rate swap instruments designated as fair value hedges and the line items on our Consolidated Balance Sheets in which they are recorded as of August 31, 2018 , and 2017 . 2018 2017 2018 2017 Balance Sheet Location Derivative Assets Balance Sheet Location Derivative Liabilities (Dollars in thousands) (Dollars in thousands) Derivative assets $ — $ — Derivative liabilities $ 771 $ — Other assets — 9,978 Other liabilities 8,681 707 Total $ — $ 9,978 Total $ 9,452 $ 707 The following table sets forth the pretax gains (losses) on derivatives accounted for as hedging instruments that have been included in our Consolidated Statements of Operations for the years ended August 31, 2018 , 2017 , and 2016 .

We also entered into pay-variable, receive-fixed, cash-settled swaps designated as cash flow hedges of future refined product sales. These hedging instruments and the related hedged items are exposed to significant market price risk and potential volatility. As part of our risk management strategy, we look to hedge a portion of our expected future crude oil needs and the resulting refined product output based on prevailing futures prices, management's expectations about future commodity price changes and our risk appetite. As of August 31, 2018, the notional amount, the fair value and the amounts recorded in other comprehensive income relating to these cash flow hedges were immaterial. There were no outstanding cash flow hedges as of August 31, 2017. In fiscal 2015, we entered into forward-starting interest rate swaps with an aggregate notional amount of $300.0 million designated as cash flow hedges of the expected variability of future interest payments on our anticipated issuance of fixed-rate debt. During the first quarter of fiscal 2016, we determined that certain of the anticipated debt issuances would be delayed; and we consequently recorded an immaterial amount of losses on the ineffective portion of the related swaps in earnings. Additionally, we paid $6.4 million in cash to settle two of the interest rate swaps upon their scheduled termination dates. During the second quarter of fiscal 2016, we settled an additional two interest rate swaps, paying $5.3 million in cash upon their scheduled termination. In January 2016, we issued the fixed-rate debt associated with these swaps and will amortize the amounts which were previously deferred to other comprehensive income into earnings over the life of the debt. The amounts to be included in earnings are not expected to be material during any 12-month period. During the third quarter of fiscal 2016, we settled the remaining two interest rate swaps, paying $5.1 million in cash upon their scheduled termination. We did not issue additional fixed-rate debt as previously planned, and we reclassified all amounts previously recorded to other comprehensive income into earnings. The following table presents the pretax gains (losses) recorded in other comprehensive income relating to cash flow hedges for the years ended August 31, 2018 , 2017 , and 2016 : 2018 2017 2016 (Dollars in thousands) Interest rate derivatives $ 178 $ — $ (10,070 ) The following table presents the pretax gains (losses) relating to cash flow hedges that were reclassified from accumulated other comprehensive loss into income for the years ended August 31, 2018 , 2017 , and 2016 : Location of Gain (Loss) 2018 2017 2016 (Dollars in thousands) Interest rate derivatives Interest expense $ (1,704 ) $ (1,742 ) $ (5,071 )

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We determine fair values of derivative instruments and certain other assets, based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. ASC Topic 820 describes three levels within its hierarchy that may be used to measure fair value, and our assessment of relevant instruments within those levels is as follows: Level 1: Values are based on unadjusted quoted prices in active markets for identical assets or liabilities. These assets and liabilities include exchange-traded derivative instruments, Rabbi Trust investments, deferred compensation investments and available-for-sale investments. Level 2: Values are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. These assets and liabilities include interest rate, foreign exchange, and commodity swaps; forward commodity contracts with a fixed price component; and other OTC derivatives whose value is determined with inputs that are based on exchange traded prices, adjusted for location specific inputs that are primarily observable in the market or can be derived principally from, or corroborated by, observable market data. Level 3: Values are generated from unobservable inputs that are supported by little or no market activity and that are a significant component of the fair value of the assets or liabilities. These unobservable inputs would reflect our own estimates of assumptions that market participants would use in pricing related assets or liabilities. Valuation techniques might include the use of pricing models, discounted cash flow models or similar techniques. The following tables present assets and liabilities, included on our Consolidated Balance Sheets, that are recognized at fair value on a recurring basis, and indicate the fair value hierarchy utilized to determine these fair values. Assets and liabilities are classified, in their entirety, based on the lowest level of input that is a significant component of the fair value measurement. The lowest level of input is considered Level 3. Our assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the classification of fair value assets and liabilities within the fair value hierarchy levels. Recurring fair value measurements at August 31, 2018 , and 2017 , are as follows: 2018 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (Dollars in thousands) Assets: Commodity derivatives $ 54,487 $ 259,359 $ — $ 313,846 Foreign currency derivatives — 15,401 — 15,401 Deferred compensation assets 39,073 — — 39,073 Embedded derivative asset — 23,595 — 23,595 Other assets 5,334 — — 5,334 Total $ 98,894 $ 298,355 $ — $ 397,249 Liabilities: Commodity derivatives $ 31,778 $ 389,911 $ — $ 421,689 Foreign currency derivatives — 24,701 — 24,701 Interest rate swap derivatives — 9,452 — 9,452 Total $ 31,778 $ 424,064 $ — $ 455,842 2017 (As Restated) Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total (Dollars in thousands) Assets: Commodity derivatives $ 48,483 $ 166,866 $ — $ 215,349 Foreign currency derivatives — 8,779 — 8,779 Interest rate swap derivatives — 9,978 — 9,978 Deferred compensation assets 52,414 — — 52,414 Deferred purchase price receivable — — 548,602 548,602 Embedded derivative — 25,533 — 25,533 Other assets 14,846 — — 14,846 Total $ 115,743 $ 211,156 $ 548,602 $ 875,501 Liabilities: Commodity derivatives $ 31,190 $ 262,140 $ — $ 293,330 Foreign currency derivatives — 19,931 — 19,931 Interest rate swap derivatives — 707 — 707 Total $ 31,190 $ 282,778 $ — $ 313,968 Commodity and foreign currency derivatives — Exchange-traded futures and options contracts are valued based on unadjusted quoted prices in active markets and are classified within Level 1. Our forward commodity purchase and sales contracts with fixed-price components, select ocean freight contracts and other OTC derivatives are determined using inputs that are generally based on exchange traded prices and/or recent market bids and offers, adjusted for location specific inputs, and are classified within Level 2. The location specific inputs are driven by local market supply and demand, and are generally based on broker or dealer quotations, or market transactions in either the listed or OTC markets. Changes in the fair values of these contracts are recognized in our Consolidated Statements of Operations as a component of cost of goods sold. Interest rate swap derivatives — Fair values of our interest rate swap derivatives are determined utilizing valuation models that are widely accepted in the market to value these OTC derivative contracts. The specific terms of the contracts, as well as market observable inputs, such as interest rates and credit risk assumptions, are factored into the models. As all significant inputs are market observable, all interest rate swaps are classified within Level 2. Changes in the fair values of contracts not designated as hedging instruments for accounting purposes are recognized in our Consolidated Statements of Operations as a component of interest expense. See Note 13, Derivative Financial Instruments and Hedging Activities for additional information about interest rates swaps designated as fair value and cash flow hedges. Deferred compensation and other assets — Our deferred compensation investments, Rabbi Trust assets and available-for-sale investments in common stock of other companies are valued based on unadjusted quoted prices on active exchanges and are classified within Level 1. Changes in the fair values of these other assets are primarily recognized in our Consolidated Statements of Operations as a component of marketing, general and administrative expenses. Embedded derivative asset — The embedded derivative asset relates to contingent payments inherent to our investment in CF Nitrogen. The inputs used in the fair value measurement include the probability of future upgrades and downgrades of CF Industries' credit rating based on historical credit rating movements of other public companies and the discount rates applied to potential annual payments based on applicable historical and current yield coupon rates. Based on these observable inputs, our fair value measurement is classified within Level 2. See Note 13, Derivative Financial Instruments and Hedging Activities for additional information. Deferred purchase price receivable — As described in Note 3, Receivables our Securitization Facility was amended during fiscal 2018 such that no DPP receivable remained as of August 31, 2018 . The fair value of the DPP receivable as of August 31, 2017 , was included in receivables, net and other assets, and was determined by discounting the expected cash flows to be received. The expected cash flows were primarily based on unobservable inputs consisting of the face amount of the Receivables adjusted for anticipated credit losses. Due to the use of significant unobservable inputs in the pricing model, including management's assumptions related to anticipated credit losses, the DPP receivable was classified as a Level 3 fair value measurement. A reconciliation of the DPP receivable for the years ended August 31, 2018 , and 2017 , is included in Note 3, Receivables .

This reclassification had no impact on our previously reported net income, cash flows or shareholders' equity and represents reclassifications for the periods ended November 30, 2017 and 2016, and February 28, 2018 and 2017. The reclassifications included a $2.8 million gain reclassification during the three months ended November 30, 2017, a $4.1 million gain reclassification during the three months ended February 28, 2018, a $7.4 million loss during the three months ended November 30, 2016, and a $2.9 million gain during the three months ended February 28, 2017. Consolidated financial statement adjustment tables The following tables present the impacts of the restatement adjustments to the previously reported financial information for the quarterly periods ended November 30, 2017 and 2016, February 28, 2018 and 2017, May 31, 2018 and 2017, and August 31, 2017. Refer to discussion in Note 2, Restatement of Previously Issued Consolidated Financial Statements . The restatement references identified in the following tables directly correlate to the restatement adjustments detailed below. The categories of restatement adjustments and their impact on previously reported consolidated financial statements are described below. (a) Freight Derivatives and Related Misstatements - Corrections for freight derivatives and related misstatements were driven by the misstatement of amounts associated with both the value and quantity of rail freight contracts, as well as due to freight contracts not meeting the technical accounting requirements to qualify as derivative financial instruments. In addition to the elimination of the underlying freight derivative assets and liabilities and related impacts on revenues and cost of goods sold, additional adjustments were recorded to account for prepaid freight capacity balances in relevant periods and the impact of a goodwill impairment charge recorded during fiscal 2015 for goodwill held within our Grain Marketing reporting unit which was triggered by the lowering of earnings due to the restatement. Additional details related to the impact of the freight derivatives and related misstatements and their impact on each period are discussed in restatement reference (a). (b) Intercompany Misstatements - As a result of the work performed in relation to the freight misstatement, additional misstatements related to the incorrect elimination of intercompany balances were also identified and corrected within the consolidated financial statements. Certain of these intercompany misstatements resulted in a misstatement of various financial statement line items; however, the intercompany misstatements did not result in a material misstatement of income (loss) before income taxes or net income (loss). Additional details related to the impact of the intercompany misstatements and their impact on each period are discussed in restatement reference (b). (c) Other Misstatements - We made adjustments for other previously identified misstatements unrelated to the freight derivatives and related misstatements that were not material, individually or in the aggregate, to our consolidated financial statements. These other misstatements related primarily to certain misclassifications, adjustments to revenues and cost of goods sold, and adjustments to various income tax and indirect tax accrual accounts. Additional details related to the impact of the other misstatements and their impact on each period are discussed in restatement reference (c). CHS INC.

The reduction of total assets related primarily to the elimination of $116.8 million of current derivative assets and a $49.2 million reduction of long-term derivative assets that had been recorded as assets on the Consolidated Balance Sheet as well as an approximate $16.0 million reduction of goodwill associated with a goodwill impairment charge recorded during fiscal 2015 The decreases of total assets were partially offset by related adjustments, including an $8.5 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $1.1 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $16.5 million reduction of current derivative liabilities and a $22.2 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities resulted from a $30.2 million increase of long-term deferred tax liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $3.4 million reduction of total assets and a $3.4 million reduction of current liabilities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $38.4 million increase of total assets, a $102.3 million increase of current liabilities, a $32.3 million decrease of long-term liabilities and a $31.6 million decrease of total equities. The increase of total assets related primarily to a $67.5 million increase of inventories that resulted from a misclassification adjustment related to $67.5 million previously included as a contra-inventory balance moving to accounts payable. The increase related to inventories was partially offset by a $28.1 million decrease of other current assets that resulted from the reduction of prepaid income taxes associated with the correction of other misstatements identified during fiscal 2018 and other periods. The increase of current liabilities related primarily to a $67.5 million increase of accounts payable that resulted from a misclassification adjustment for amounts previously included as a contra-inventory balance to accounts payable and a $38.6 million increase of accrued expenses. The increase of accrued expenses related to the recognition of a $24.9 million accrued income tax balance associated with the correction of other misstatements identified during fiscal 2018 and other periods, as well as the recognition of $13.7 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. Long-term liabilities decreased primarily as a result of a $32.1 million decrease of long-term deferred tax liabilities related to the correction of other misstatements identified during fiscal 2018 and other periods. The $31.6 million decrease of total equities related primarily to the impacts associated with the $20.6 million net impact on income tax accounts and the recognition of an additional $13.7 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. As of November 30, 2016 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $145.5 million reduction of total assets, a $47.0 million reduction of current liabilities, a $15.5 million increase of long-term liabilities and a $114.0 million reduction of total equities. The reduction of total assets related primarily to the elimination of $141.0 million of current derivative assets that had been incorrectly recorded as assets on the Consolidated Balance Sheet and an approximate $16.0 million reduction of goodwill associated with a goodwill impairment charge recorded during fiscal 2015. The decreases of total assets were partially offset by related adjustments, including a $4.0 million increase of receivables, a $5.7 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $0.9 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $35.0 million reduction of current derivative liabilities and a $20.7 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. These decreases of current liabilities were partially offset by an $8.7 million increase of accounts payable. The increase of long-term liabilities resulted from a $15.5 million increase of long-term deferred tax liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $73.3 million reduction of total assets, an $85.4 million reduction of current liabilities and a $12.1 million increase of total equities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $63.9 million increase of total assets, a $74.6 million increase of current liabilities, a $0.9 million decrease of long-term liabilities and a $9.9 million decrease of total equities. The increase of total assets related primarily to a misclassification adjustment for $73.8 million previously included as a contra-inventory balance moving to accounts payable. The increased inventories were partially offset by a $48.2 million reduction of inventory related to a misclassification adjustment for certain collateral moving from inventory to receivables. The increase of total liabilities relates primarily to a misclassification adjustment for $73.8 million previously included as a contra-inventory balance moving to accounts payable. The $9.9 million decrease of total equities relates primarily to the $28.8 million net impact on income tax accounts and the recognition of $8.1 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. The overall decrease in total equities was partially offset by an increase that arose from a $27.9 million timing difference for the accrual of dividends and equities payable. CHS INC.

The reduction of total assets related primarily to the elimination of $179.3 million of current derivative assets which had been incorrectly recorded as assets on the Consolidated Balance Sheet and an approximate $16.0 million impairment of goodwill which was triggered when earnings were lowered due to the restatement. The decrease of total assets was partially offset by a related adjustment to increase prepaid income taxes by $9.7 million as a result of the income tax impact of the freight misstatement. The decrease of total current liabilities related primarily to a $7.1 million reduction of current derivative liabilities and a $19.7 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities was primarily attributable to the $28.9 million increase of long-term deferred tax liabilities. The decrease of total equities was related primarily to the elimination of derivative assets and liabilities from the Consolidated Balance Sheet as described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $5.6 million reduction of total assets and a $5.6 million reduction of current liabilities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. These misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $108.0 million increase of total assets, a $153.1 million increase of current liabilities, a $35.4 million decrease of long-term liabilities and a $9.7 million decrease of total equities. The increase of total assets related primarily to a $28.8 million increase of cash that resulted from a timing difference for the application of in-transit cash and a $78.2 million increase of receivables and notes payable related to a participation arrangement that did not meet certain criteria for off-balance sheet treatment. As a result, both receivables and notes payable were increased by $78.2 million . The increase of current liabilities related primarily to the $78.2 million increase of receivables and notes payable in a participation arrangement that did not meet certain criteria for off-balance sheet treatment, a $29.1 million increase of customer advance payments that resulted from a timing difference related to the application of in-transit cash and a $27.9 million increase of accounts payable that had previously been included as a contra-inventory balance. Long-term liabilities decreased primarily due to the recognition of long-term deferred tax liabilities of $35.1 million related to the correction of other misstatements identified during fiscal 2018 and other periods. The $9.7 million decrease of total equities relates primarily to the $14.1 million net impact on income tax accounts, which was partially offset by a $4.5 million increase related to the valuation of crack spread derivatives. As of February 28, 2017 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $160.3 million reduction of total assets, a $61.3 million reduction of current liabilities, a $15.8 million increase of long-term liabilities and a $114.7 million reduction of total equities. The reduction of total assets related primarily to the elimination of $153.0 million of current derivative assets that were incorrectly recorded as assets on the Consolidate Balance Sheet and an approximate $16.0 million impairment of goodwill recorded in fiscal 2015 associated with lower earnings as a result of the restatement. The overall decrease of total assets was partially offset by related adjustments, including a $6.4 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $0.6 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $43.0 million reduction of current derivative liabilities and a $20.7 million reduction of income t

Organization, Basis of Presentation and Significant Accounting Policies (Policies)	12 Months Ended
	Aug. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements include the accounts of CHS and all wholly-owned and majority-owned subsidiaries and limited liability companies. The effects of all significant intercompany transactions have been eliminated. As described in Note 2, Restatement of Previously Issued Consolidated Financial Statements the consolidated financial statements for the years ended August 31, 2017 and 2016, have been restated to reflect the correction of misstatements to the consolidated financial statements. We have also restated all amounts impacted within the Notes to the consolidated financial statements. Over the course of fiscal 2017, we incurred charges related to a trading partner of ours in Brazil, which entered into bankruptcy-like proceedings under Brazilian law; intangible and fixed asset impairment charges associated with certain assets meeting the criteria to be classified as held for sale; fixed asset impairment charges due to the cancellation of a capital project at one of our refineries; and bad debt/loan loss reserve charges relating to a single large producer borrower. Charges and impairments of this nature, as well as any recoveries related to amounts previously reserved, are included in the Consolidated Statements of Operations in the line item, "reserve and impairment charges (recoveries), net" for the twelve months ended August 31, 2018 , 2017 , and 2016 . The timing and amounts of these charges and impairments, and any recoveries were determined utilizing facts and circumstances that were present in the respective years in which the charges, impairments or recoveries were recorded. See additional information related to the reserves and impairment charges in Note 3, Receivables, Note 6 , Property, Plant and Equipment , and Note 7 , Other Assets . The notes to our consolidated financial statements refer to our Energy, Ag and Nitrogen Production reportable segments, as well as our Corporate and Other category, which represents an aggregation of individually immaterial operating segments. The Nitrogen Production reportable segment resulted from our investment in CF Industries Nitrogen, LLC ("CF Nitrogen") in February 2016. Our investment in Ventura Foods, LLC ("Ventura Foods") is no longer a significant operating segment and is now included in our Corporate and Other category. See Note 12, Segment Reporting for more information.
Major Maintenance Activities	Major Maintenance Activities Within our Energy segment, major maintenance activities (“turnarounds”) are performed at our Laurel, Montana and McPherson, Kansas refineries regularly. Turnarounds are the planned and required shutdowns of refinery processing units, which include the replacement or overhaul of equipment that have experienced decreased efficiency in resource conversion. Because turnarounds are performed to extend the life, increase the capacity, and/or improve the safety or efficiency of refinery processing assets, we follow the deferral method of accounting for turnarounds. Expenditures for turnarounds are capitalized (deferred) when incurred and amortized on a straight-line basis over a period of 2 to 4 years, which is the estimated time lapse between turnarounds. Should the estimated period between turnarounds change, we may be required to amortize the remaining cost of the turnaround over a shorter period, which would result in higher depreciation and amortization costs. Capitalized turnaround costs are included in other assets (long-term) on our Consolidated Balance Sheets and amortization expense related to the capitalized turnaround costs is included in cost of goods sold in our Consolidated Statements of Operations. The selection of the deferral method, as opposed to expensing the turnaround costs when incurred, results in deferring recognition of the turnaround expenditures. The deferral method also results in the classification of the related cash outflows as investing activities in our Consolidated Statements of Cash Flows, whereas expensing these costs as incurred would result in classifying the cash outflows as operating activities. Repair, maintenance and related labor costs are expensed as incurred and are included in operating cash flows.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates on assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Due to the inherent uncertainty involved in making estimates, actual results could differ from those estimates. We evaluate our estimates and assumptions on an ongoing basis.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash equivalents include short-term, highly liquid investments with original maturities of three months or less at the date of acquisition. The fair value of cash and cash equivalents approximates the carrying value due to the short-term nature of the instruments.
Inventories	Inventories Grain, processed grain, oilseed, processed oilseed and other minimally processed soy-based inventories are stated at net realizable value. These inventories are agricultural commodity inventories that are readily convertible to cash because of their commodity characteristics, widely available markets and international pricing mechanisms. Agricultural commodity inventories have quoted market prices in active markets, may be sold without significant further processing and have predictable and insignificant disposal costs. Changes in the net realizable value of merchandisable agricultural commodities inventories are recognized in earnings as a component of cost of goods sold. All other inventories are stated at the lower of cost or net realizable value. Costs for inventories produced or modified by us through a manufacturing process include fixed and variable production and raw material costs, and in-bound freight costs for raw materials. Costs for inventories purchased for resale include the cost of products and freight incurred to place the products at our points of sale. The costs of certain energy inventories (wholesale refined products, crude oil and asphalt) are determined on the last-in, first-out ("LIFO") method; all other inventories of non-grain products purchased for resale are valued on the first-in, first-out ("FIFO") and average cost methods.
Derivative Financial Instruments and Hedging Activities	Derivative Financial Instruments and Hedging Activities We enter into various derivative instruments to manage our exposure to movements primarily associated with agricultural commodity prices and to a lesser degree, foreign currency exchange rates and interest rates. Except for certain interest rate swap contracts, which are accounted for as cash flow hedges or fair value hedges, our derivative instruments represent economic hedges of price risk for which hedge accounting under Accounting Standards Codification ("ASC") Topic 815, Derivatives and Hedging , is not applied. Rather, the derivative instruments are recorded on our Consolidated Balance Sheets at fair value with changes in fair value being recorded directly to earnings, primarily within cost of goods sold in our Consolidated Statements of Operations. See Note 13, Derivative Financial Instruments and Hedging Activities and Note 14, Fair Value Measurements for additional information. Although we have certain netting arrangements for our exchange-traded futures and options contracts and certain over-the-counter ("OTC") contracts, we have elected to report our derivative instruments on a gross basis on our Consolidated Balance Sheets under ASC Topic 210-20, Balance Sheet - Offsetting .
Margin and Related Deposits	Margin and Related Deposits Many of our derivative contracts with futures and options brokers require us to make margin deposits of cash or other assets. Subsequent margin deposits may also be necessary when changes in commodity prices result in a loss on the contract value, to comply with applicable regulations. Our margin and related deposit assets are held by external brokers in segregated accounts to support the associated derivative contracts and may be used to fund or partially fund the settlement of those contracts as they expire. Similar to our derivative financial instruments, margin and related deposits are also reported on a gross basis.
Supplier Advance Payments and Rebates	Supplier Advance Payments and Rebates Supplier advance payments are typically for periods less than 12 months and primarily include amounts paid for grain purchases from suppliers and amounts paid to crop nutrient suppliers to lock in future supply and pricing.
Investments	Investments The equity method of accounting is used for joint ventures and other investments in which we are able to exercise significant influence over the entity’s operations, but do not have a controlling interest in the entity. Various factors are considered when assessing significant influence, including our ownership interest, representation on the Board of Directors, voting rights, and the impact of commercial arrangements that may exist with the entity. Our equity in the income or loss of these equity method investments is recorded within equity (income) loss from investments in the Consolidated Statements of Operations. We account for our investment in CF Nitrogen, LLC using the hypothetical liquidation at book value method which is discussed further in Note 5 , Investments. The cost method of accounting is used for other investments in which we do not exercise significant influence. Investments in other cooperatives are stated at cost, plus patronage dividends received in the form of capital stock and other equities. Patronage dividends are recorded as a reduction to cost of goods sold at the time qualified written notices of allocation are received. Investments in other debt and equity securities are classified as available-for-sale financial instruments and are stated at fair value, with unrealized gains and losses included as a component of accumulated other comprehensive loss on our Consolidated Balance Sheets. Investments in debt and equity instruments are carried at amounts that approximate fair values.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided on the straight-line method by charges to operations at rates based on the expected useful lives of individual or groups of assets (generally 15 to 20 years for land improvements; 20 to 40 years for buildings; 5 to 20 years for machinery and equipment; and 3 to 10 years for office equipment and other). Expenditures for maintenance and minor repairs and renewals are expensed, while the costs for major maintenance activities are capitalized and amortized on a straight-line basis over the period estimated to lapse until the next major maintenance activity occurs. We also capitalize and amortize eligible costs to acquire or develop internal-use software that are incurred during the application development stage. When assets are sold or otherwise disposed of, the cost and related accumulated depreciation and amortization are removed from the related accounts and resulting gains or losses are reflected in operations. Property, plant and equipment and other long-lived assets are reviewed for impairment when events or changes in circumstances indicate that the carrying amounts may not be recoverable. This evaluation of recoverability is based on various indicators, including the nature, future economic benefits and geographic locations of the assets, historical or future profitability measures, and other external market conditions. If these indicators suggest that the carrying amounts of an asset or asset group may not be recoverable, potential impairment is evaluated using undiscounted estimated future cash flows. Should the sum of the expected future net cash flows be less than the carrying value, an impairment loss would be recognized. An impairment loss would be measured at the amount by which the carrying value of the asset or asset group exceeds its fair value. We have asset retirement obligations with respect to certain of our refineries and other assets due to various legal obligations to clean and/or dispose of the component parts at the time they are retired. In most cases, these assets can be used for extended and indeterminate periods of time if they are properly maintained and/or upgraded. It is our practice and current intent to maintain refineries and related assets and to continue making improvements to those assets based on technological advances. As a result, we believe our refineries and related assets have indeterminate lives for purposes of estimating asset retirement obligations because dates or ranges of dates upon which we would retire a refinery and related assets cannot reasonably be estimated at this time. When a date or range of dates can reasonably be estimated for the retirement of any component part of a refinery or other asset, we estimate the cost of performing the retirement activities and record a liability for the fair value of that future cost. We have other assets that we may be obligated to dismantle at the end of corresponding lease terms subject to lessor discretion for which we have recorded asset retirement obligations. Based on our estimates of the timing, cost and probability of removal, these obligations are not material.
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets Goodwill and other intangible assets are included in other assets (long-term) on our Consolidated Balance Sheets. Goodwill represents the excess of cost over the fair value of identifiable assets acquired. Goodwill is tested for impairment on an annual basis as of July 31, or more frequently if triggering events or other circumstances occur which could indicate impairment. Goodwill is tested for impairment at the reporting unit level, which has been determined to be our operating segments or one level below our operating segments in certain instances. Other intangible assets consist primarily of customer lists, trademarks and non-compete agreements. Intangible assets subject to amortization are expensed over their respective useful lives, which generally range from 2 to 30 years. We have no material intangible assets with indefinite useful lives. See Note 7, Other Assets for more information on goodwill and other intangible assets.
Revenue Recognition	Revenue Recognition We provide a wide variety of products and services, ranging from agricultural inputs such as fuels, farm supplies and crop nutrients, to agricultural outputs that include grain and oilseed, processed grains and oilseeds and food products, and ethanol production and marketing. We recognize revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Sales are generally recognized upon transfer of title, which could occur either upon shipment to or receipt by the customer, depending upon the terms of the transaction. Shipping and handling amounts billed to a customer as part of a sales transaction are included in revenues, and the related costs are included in cost of goods sold.
Environmental Expenditures	Environmental Expenditures We are subject to various federal, state, and local environmental laws and regulations. Environmental expenditures are expensed or capitalized depending on their future economic benefit. Liabilities, including legal costs, related to remediation of contaminated properties are recognized when the related costs are considered probable and can be reasonably estimated. Estimates of environmental costs are based on current available facts, existing technology, undiscounted site-specific costs and currently enacted laws and regulations. Recoveries, if any, are recorded in the period in which recovery is received. Liabilities are monitored and adjusted as new facts or changes in law or technology occur.
Income Taxes	Income Taxes CHS is a nonexempt agricultural cooperative and files a consolidated federal income tax return within our tax return period. We are subject to tax on income from nonpatronage sources, non-qualified patronage distributions and undistributed patronage-sourced income. Income tax expense is primarily the current tax payable for the period and the change during the period in certain deferred tax assets and liabilities. Deferred income taxes reflect the impact of temporary differences between the amounts of assets and liabilities recognized for financial reporting purposes and such amounts recognized for federal and state income tax purposes, based on enacted tax laws and statutory tax rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Reserves are recorded against unrecognized tax benefits when we believe that certain fully supportable tax return positions are likely to be challenged and that we may or may not prevail. If we determine that a tax position is more likely than not to be sustained upon audit, based on the technical merits of the position, we recognize the benefit by measuring the amount that is greater than 50% likely of being realized. We reevaluate the technical merits of our tax positions and recognize an uncertain tax benefit, or derecognize a previously recorded tax benefit, when there is (i) a completion of a tax audit, (ii) effective settlement of an issue, (iii) a change in applicable tax law including a tax case or legislative guidance, or (iv) the expiration of the applicable statute of limitations. Significant judgment is required in accounting for tax reserves.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Adopted In March 2018, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") No. 2018-05, Income Taxes (Topic 740) - Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. This ASU provides guidance on the income tax accounting implications of the Tax Cuts and Jobs Act of 2017 (the "Tax Act") and allows for entities to report provisional amounts for specific income tax effects of the Tax Act for which the accounting under ASC Topic 740 was not yet complete, but a reasonable estimate could be determined. A measurement period of one year is available to complete the accounting effects under ASC Topic 740 and revise any previous estimates reported. Any provisional amounts or subsequent adjustments included in an entity’s financial statements during the measurement period should be included in income from continuing operations as an adjustment to tax expense in the reporting period the amounts are determined. As of August 31, 2018, we have not finalized our work associated with the income tax effects of the enactment of the Tax Act, however, a reasonable estimate was provisionally recorded as a net benefit of $155.2 million from the revaluation of our U.S. net deferred tax liability that resulted from the reduced corporate tax rate and CHS being subject to the employee compensation deduction limitations imposed by Internal Revenue Code Section 162(m). In February 2018, the FASB issued ASU No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220). Under existing U.S. GAAP, the effects of changes in tax rates and laws on deferred tax balances are recorded as a component of income tax expense in the period in which the law was enacted. When deferred tax balances related to items originally recorded in accumulated other comprehensive income are adjusted, certain tax effects become stranded in accumulated other comprehensive income. The amendments in ASU 2018-02 allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Act. The amendments in this ASU also require certain disclosures about stranded tax effects. This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. Early adoption in any period is permitted. The Company’s provisional adjustments recorded to account for the impact of the Tax Act resulted in stranded tax effects. We elected to early adopt ASU No. 2018-02 during the fourth quarter of fiscal 2018. The adoption resulted in a reclassification from accumulated other comprehensive income to retained earnings in the amount of $27.0 million for stranded tax effects resulting from the Tax Act. In August 2017, the FASB issued ASU No. 2017-12 , Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities . This ASU is intended to improve the financial reporting of hedging relationships to better represent the economic results of an entity’s risk management activities in its financial statements and make certain improvements to simplify the application of the hedge accounting guidance. The amendments in this ASU will make more financial and nonfinancial hedging strategies eligible for hedge accounting, amend the presentation and disclosure requirements and change how entities assess effectiveness. Entities are required to apply this ASU's provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. We elected to early adopt ASU No. 2017-12 during the fourth quarter of fiscal 2018. The adoption did not have a material impact on our consolidated financial statements. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory (Topic 740). This ASU is intended to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory by requiring an entity to recognize the income tax consequences when a transfer occurs, instead of when an asset is sold to an outside party. This ASU is effective for periods beginning after December 15, 2017; however, early adoption of this ASU is permitted during the first interim period if an entity issues interim financial statements. The amendments in this ASU should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We elected to early adopt ASU No. 2016-16 during the first quarter of fiscal 2018. The adoption did not have a material impact on our consolidated financial statements. Not Yet Adopted In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans , which amends ASC 715-20, Compensation - Retirement Benefits - Defined Benefit Plans - General . This ASU modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans by removing and adding certain disclosures for these plans. The eliminated disclosures include (a) the amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year and (b) the effects of a one-percentage-point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. The new disclosures include the interest crediting rates for cash balance plans and an explanation of significant gains and losses related to changes in benefit obligations. This ASU is effective for us beginning September 1, 2021, for our fiscal year 2022 and for interim periods within that fiscal year, with early adoption permitted. The adoption of this amended guidance in not expected to have a material impact on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement , which amends ASC 820, Fair Value Measurement . This ASU modifies the disclosure requirements for fair value measurements by removing, modifying and adding certain disclosures. Specifically, the guidance removes the requirement to disclose the amount and reasons for any transfers between Level 1 and Level 2 of the fair value hierarchy and removes the requirement to disclose a description of the valuation processes used to value Level 3 fair value measurements. The guidance also requires additional disclosures surrounding Level 3 changes in unrealized gains/losses included in other comprehensive income as well the range and weighted average significant unobservable inputs calculation. This ASU is effective for us beginning September 1, 2020, for our fiscal year 2021 and for interim periods within that fiscal year. Early adoption is permitted. We elected to remove the disclosures permitted by ASU No. 2018-13 during the fourth quarter of fiscal 2018 but have not early adopted the new required additional disclosures, which is permitted by the guidance. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In March 2017, the FASB issued ASU No. 2017-07, Compensation - Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Costs and Net Postretirement Benefit Cost. This ASU changes the presentation of net periodic pension cost and net periodic postretirement benefit cost in the Consolidated Statements of Operations. This ASU provides that the service cost component should be included in the same income statement line item as other compensation costs arising from services rendered by the employees during the period. The other components of net periodic benefit cost should be presented in the Consolidated Statements of Operations separately outside of operating income if that subtotal is presented. Additionally, only service cost may be capitalized in assets. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted as of the beginning of an annual period for which interim financial statements have not been issued or made available for issuance. The guidance on the presentation of the components of net periodic benefit cost in the Consolidated Statement of Operations should be applied retrospectively and the guidance regarding the capitalization of the service cost component in assets should be applied prospectively. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805) : Clarifying the Definition of a Business . The amendments within this ASU narrow the existing definition of a business and provide a more robust framework for evaluating whether a transaction should be accounted for as an acquisition (or disposal) of assets or a business. The definition of a business impacts various areas of accounting, including acquisitions, disposals and goodwill. Under the new guidance, fewer acquisitions are expected to be considered businesses. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted, and the guidance should be applied prospectively to transactions following the adoption date. The adoption of this amended guidance is not expected to have a material impact on our consolidated financial statements. In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash . This ASU is intended to reduce diversity in practice by adding or clarifying guidance on classification and presentation of changes in restricted cash on the Consolidated Statements of Cash Flows. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. Early adoption is permitted, including in an interim period. The amendments in this ASU should be applied retrospectively to all periods presented. The adoption of this amended guidance is not expected to have a material impact on our Consolidated Statements of Cash Flows. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU is intended to reduce existing diversity in practice in how certain cash receipts and payments are presented and classified in the Consolidated Statements of Cash Flows. This ASU is effective for us beginning September 1, 2018, for our fiscal year 2019 and for interim periods within that fiscal year. The adoption of this amended guidance is not expected to have a material impact on our Consolidated Statements of Cash Flows. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (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 this ASU’s provisions as a cumulative-effect adjustment to retained earnings 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. We are currently evaluating the impact the adoption will have on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which replaces the existing guidance in ASC 840 - Leases . The amendments within this ASU, as well as within additional clarifying ASUs issued by the FASB, introduce a lessee model requiring entities to recognize assets and liabilities for most leases, but continue recognizing the associated expenses in a manner similar to existing accounting guidance. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases , which amends ASU No. 2016-02, Leases . This ASU is effective for us beginning September 1, 2019, for our fiscal year 2020 and for interim periods within that fiscal year. We have initiated our assessment of the new lease standard, including the utilization of surveys to gather more information about existing leases and the implementation of a new lease software to improve the collection, maintenance, and aggregation of lease data necessary for the expanded reporting and disclosure requirements under the new lease standard. It is expected that the primary impact upon adoption will be the recognition, on a discounted basis, of our minimum commitments under noncancelable operating leases as right of use assets and liabilities on our Consolidated Balance Sheets. This will result in a significant increase in assets and liabilities recorded on our Consolidated Balance Sheets. Although we expect the new lease guidance to have a material impact on our Consolidated Balance Sheets, we are continuing to evaluate the practical expedient guidance provisions available and the extent of potential impacts on our consolidated financial statements, processes, and internal controls. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers . The amendments within this ASU, as well as within additional clarifying ASUs issued by the FASB, provide a single comprehensive model to be used in the accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The new revenue recognition guidance includes a five-step model for the recognition of revenue, including (1) identifying the contract with a customer, (2) identifying the performance obligations in the contract, (3) determining the transaction price, (4) allocating the transaction price to the performance obligations, and (5) recognizing revenue when (or as) an entity satisfies a performance obligation. The adoption of the new revenue recognition guidance will require expanded disclosures in our consolidated financial statements including quantitative disclosure of revenues that fall within and outside the scope of the new revenue recognition guidance. Certain revenue streams are expected to fall within the scope of the new revenue recognition guidance; however, a substantial portion of our revenue falls outside the scope of the new revenue recognition guidance and will continue to follow existing guidance, primarily ASC 815, Derivatives and Hedging . We have completed an initial assessment of our revenue streams and do not believe that the new revenue recognition guidance will have a material impact on our consolidated financial statements. We will adopt ASU No. 2014-09 and the related ASUs using the modified retrospective method on September 1, 2018, in the first quarter of fiscal 2019.
Fair Value Measurements	ASC Topic 820, Fair Value Measurement defines fair value as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. We determine fair values of derivative instruments and certain other assets, based on the fair value hierarchy established in ASC Topic 820, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Observable inputs are inputs that reflect the assumptions market participants would use in pricing the asset or liability based on the best information available in the circumstances. ASC Topic 820 describes three levels within its hierarchy that may be used to measure fair value, and our assessment of relevant instruments within those levels is as follows: Level 1: Values are based on unadjusted quoted prices in active markets for identical assets or liabilities. These assets and liabilities include exchange-traded derivative instruments, Rabbi Trust investments, deferred compensation investments and available-for-sale investments. Level 2: Values are based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. These assets and liabilities include interest rate, foreign exchange, and commodity swaps; forward commodity contracts with a fixed price component; and other OTC derivatives whose value is determined with inputs that are based on exchange traded prices, adjusted for location specific inputs that are primarily observable in the market or can be derived principally from, or corroborated by, observable market data. Level 3: Values are generated from unobservable inputs that are supported by little or no market activity and that are a significant component of the fair value of the assets or liabilities. These unobservable inputs would reflect our own estimates of assumptions that market participants would use in pricing related assets or liabilities. Valuation techniques might include the use of pricing models, discounted cash flow models or similar techniques.
Fair Value of Financial Instruments	Commodity and foreign currency derivatives — Exchange-traded futures and options contracts are valued based on unadjusted quoted prices in active markets and are classified within Level 1. Our forward commodity purchase and sales contracts with fixed-price components, select ocean freight contracts and other OTC derivatives are determined using inputs that are generally based on exchange traded prices and/or recent market bids and offers, adjusted for location specific inputs, and are classified within Level 2. The location specific inputs are driven by local market supply and demand, and are generally based on broker or dealer quotations, or market transactions in either the listed or OTC markets. Changes in the fair values of these contracts are recognized in our Consolidated Statements of Operations as a component of cost of goods sold. Interest rate swap derivatives — Fair values of our interest rate swap derivatives are determined utilizing valuation models that are widely accepted in the market to value these OTC derivative contracts. The specific terms of the contracts, as well as market observable inputs, such as interest rates and credit risk assumptions, are factored into the models. As all significant inputs are market observable, all interest rate swaps are classified within Level 2. Changes in the fair values of contracts not designated as hedging instruments for accounting purposes are recognized in our Consolidated Statements of Operations as a component of interest expense. See Note 13, Derivative Financial Instruments and Hedging Activities for additional information about interest rates swaps designated as fair value and cash flow hedges. Deferred compensation and other assets — Our deferred compensation investments, Rabbi Trust assets and available-for-sale investments in common stock of other companies are valued based on unadjusted quoted prices on active exchanges and are classified within Level 1. Changes in the fair values of these other assets are primarily recognized in our Consolidated Statements of Operations as a component of marketing, general and administrative expenses. Embedded derivative asset — The embedded derivative asset relates to contingent payments inherent to our investment in CF Nitrogen. The inputs used in the fair value measurement include the probability of future upgrades and downgrades of CF Industries' credit rating based on historical credit rating movements of other public companies and the discount rates applied to potential annual payments based on applicable historical and current yield coupon rates. Based on these observable inputs, our fair value measurement is classified within Level 2. See Note 13, Derivative Financial Instruments and Hedging Activities for additional information. Deferred purchase price receivable — As described in Note 3, Receivables our Securitization Facility was amended during fiscal 2018 such that no DPP receivable remained as of August 31, 2018 . The fair value of the DPP receivable as of August 31, 2017 , was included in receivables, net and other assets, and was determined by discounting the expected cash flows to be received. The expected cash flows were primarily based on unobservable inputs consisting of the face amount of the Receivables adjusted for anticipated credit losses. Due to the use of significant unobservable inputs in the pricing model, including management's assumptions related to anticipated credit losses, the DPP receivable was classified as a Level 3 fair value measurement.
Equity Method Investments	Joint ventures and other investments in which we have significant ownership and influence but not control, are accounted for in our consolidated financial statements using the equity method of accounting. Our significant equity method investments consist of CF Nitrogen, Ventura Foods, and Ardent Mills, LLC ("Ardent Mills"), which are summarized below.

The reduction of total assets related primarily to the elimination of $156.0 million of long-term derivative assets, an approximate $16.0 million reduction of goodwill which was triggered by the lower earnings associated with this restatement with the impairment charge recorded during fiscal 2015 and the elimination of $12.9 million of current derivative assets that had been recorded as assets on the Consolidated Balance Sheet. The decreases of total assets were partially offset by related adjustments, including an $8.9 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $1.5 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to an $18.0 million reduction of current derivative liabilities and a $21.1 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities resulted from a $28.9 million increase of long-term deferred tax liabilities, which was partially offset by a $1.4 million reduction of long-term derivative liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) None Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of certain income tax adjustments on prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the impact of income tax adjustments resulted in a $19.3 million increase of total assets, an $89.1 million increase of current liabilities, a $32.1 million decrease of long-term liabilities and a $37.7 million decrease of total equities. The increase of total assets related primarily to a $49.2 million increase of inventory with a corresponding increase to accounts payable that resulted from a misclassification adjustment for certain items previously included within a contra-inventory account to accounts payable. The increased inventories were partially offset by a $24.1 million misclassification adjustment to decrease inventory and increase accounts receivable as a result of a timing difference related to the settlement of a single ocean vessel. The increase of total assets was partially offset by a $28.1 million decrease of prepaid income taxes associated with the correction of other misstatements identified during fiscal 2017 and other periods. The increase of current liabilities related primarily to the $49.2 million increase of accounts payable as a result of a misclassification adjustment for certain items previously included within a contra-inventory account to accounts payable and a $38.6 million increase of accrued expenses. The increase of accrued expenses primarily resulted from the recognition of a $24.9 million accrued income tax balance associated with the correction of other misstatements identified during fiscal 2017 and other periods. Additionally, $13.7 million of accrued expenses were recorded in relation to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. The decrease of long-term liabilities related to a $32.1 million decrease of long-term deferred tax liabilities that arose from the correction of other misstatements identified during fiscal 2017 and other periods. The $37.7 million decrease of total equities was primarily related to the $20.6 million net impact on income tax accounts and the recognition of $13.7 million of additional accrued expenses due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018.

These adjustments related primarily to a $38.1 million increase of cost of goods sold and a $9.2 million increase of income tax expense resulting from the tax effect of the freight derivatives and related misstatements. Intercompany misstatements (b) The correction of intercompany misstatements had no impact on income (loss) before income taxes or net income (loss); however, the correction resulted in a $35.7 million decrease of both revenues and cost of goods sold due to different practices of eliminating intercompany sales between CHS's businesses which existed in previous periods. Other misstatements (c) The correction of other misstatements resulted in a $17.2 million decrease of income before income taxes and a $9.0 million decrease of net income. The $17.2 million decrease of income before income taxes related to a $12.1 million increase of cost of goods sold due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018, a $2.6 million combined increase in cost of goods sold and marketing, general and administrative expenses for postretirement benefit plan activity that resulted from a timing difference associated with recording certain benefit plan expenses and a $2.5 million increase of costs of goods sold related to the valuation of crack spread derivatives. An income tax benefit of $8.2 million partially offset the decrease of income before income taxes and was recorded to adjust for the impact of other identified misstatements, as well as income tax items that had previously been identified and recorded as out of period adjustments in subsequent periods. Additionally, certain misclassification and offsetting adjustments were made between line items included in the Consolidated Statements of Operations primarily due to the application of differing accounting policies between businesses. These misclassification adjustments resulted in a $138.4 million increase of revenues, a $138.3 million increase of cost of goods sold, a $7.0 million increase of marketing, general and administrative expenses, a $2.2 million increase of loss on disposal of business and a $9.1 million increase of other income. For the year ended August 31, 2016 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $15.7 million reduction of income before income taxes and a $9.9 million reduction of net income. These adjustments related to a $15.7 million increase of cost of goods sold and a $5.8 million income tax benefit resulting from the tax effect of the freight derivatives and related misstatements. Intercompany misstatements (b) The correction of intercompany misstatements had no impact on income (loss) before income taxes or net income (loss); however, the correction resulted in a $57.5 million decrease of both revenues and cost of goods sold due to different practices of eliminating intercompany sales between CHS's businesses which existed in previous periods. Other misstatements The correction of other misstatements resulted in a $2.1 million decrease of income before income taxes and a $31.0 million decrease of net income. The $2.1 million decrease of income before income taxes related to a $1.7 million increase of cost of goods sold due to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018 and a $0.4 million increase of costs of goods sold related to the valuation of crack spread derivatives. In addition to the decrease of income before income taxes, additional income tax expense of $29.0 million was recorded to adjust for the impact of other identified misstatements, as well as income tax items that had previously been identified and recorded as out of period adjustments in subsequent periods. Additionally, misclassification and offsetting adjustments were made between line items included in the Consolidated Statements of Operations primarily due to the application of differing accounting policies between businesses between businesses. These adjustments resulted in a $65.6 million increase of revenues, a $38.4 million increase of cost of goods sold and a $27.2 million increase of reserve and impairment charges (recoveries), net.

This reclassification had no impact on our previously reported net income, cash flows or shareholders' equity and represents reclassifications for the periods ended November 30, 2017 and 2016, and February 28, 2018 and 2017. The reclassifications included a $2.8 million gain reclassification during the three months ended November 30, 2017, a $4.1 million gain reclassification during the three months ended February 28, 2018, a $7.4 million loss during the three months ended November 30, 2016, and a $2.9 million gain during the three months ended February 28, 2017. Consolidated financial statement adjustment tables The following tables present the impacts of the restatement adjustments to the previously reported financial information for the quarterly periods ended November 30, 2017 and 2016, February 28, 2018 and 2017, May 31, 2018 and 2017, and August 31, 2017. Refer to discussion in Note 2, Restatement of Previously Issued Consolidated Financial Statements . The restatement references identified in the following tables directly correlate to the restatement adjustments detailed below. The categories of restatement adjustments and their impact on previously reported consolidated financial statements are described below. (a) Freight Derivatives and Related Misstatements - Corrections for freight derivatives and related misstatements were driven by the misstatement of amounts associated with both the value and quantity of rail freight contracts, as well as due to freight contracts not meeting the technical accounting requirements to qualify as derivative financial instruments. In addition to the elimination of the underlying freight derivative assets and liabilities and related impacts on revenues and cost of goods sold, additional adjustments were recorded to account for prepaid freight capacity balances in relevant periods and the impact of a goodwill impairment charge recorded during fiscal 2015 for goodwill held within our Grain Marketing reporting unit which was triggered by the lowering of earnings due to the restatement. Additional details related to the impact of the freight derivatives and related misstatements and their impact on each period are discussed in restatement reference (a). (b) Intercompany Misstatements - As a result of the work performed in relation to the freight misstatement, additional misstatements related to the incorrect elimination of intercompany balances were also identified and corrected within the consolidated financial statements. Certain of these intercompany misstatements resulted in a misstatement of various financial statement line items; however, the intercompany misstatements did not result in a material misstatement of income (loss) before income taxes or net income (loss). Additional details related to the impact of the intercompany misstatements and their impact on each period are discussed in restatement reference (b). (c) Other Misstatements - We made adjustments for other previously identified misstatements unrelated to the freight derivatives and related misstatements that were not material, individually or in the aggregate, to our consolidated financial statements. These other misstatements related primarily to certain misclassifications, adjustments to revenues and cost of goods sold, and adjustments to various income tax and indirect tax accrual accounts. Additional details related to the impact of the other misstatements and their impact on each period are discussed in restatement reference (c). CHS INC.

The reduction of total assets related primarily to the elimination of $116.8 million of current derivative assets and a $49.2 million reduction of long-term derivative assets that had been recorded as assets on the Consolidated Balance Sheet as well as an approximate $16.0 million reduction of goodwill associated with a goodwill impairment charge recorded during fiscal 2015 The decreases of total assets were partially offset by related adjustments, including an $8.5 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $1.1 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $16.5 million reduction of current derivative liabilities and a $22.2 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities resulted from a $30.2 million increase of long-term deferred tax liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $3.4 million reduction of total assets and a $3.4 million reduction of current liabilities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $38.4 million increase of total assets, a $102.3 million increase of current liabilities, a $32.3 million decrease of long-term liabilities and a $31.6 million decrease of total equities. The increase of total assets related primarily to a $67.5 million increase of inventories that resulted from a misclassification adjustment related to $67.5 million previously included as a contra-inventory balance moving to accounts payable. The increase related to inventories was partially offset by a $28.1 million decrease of other current assets that resulted from the reduction of prepaid income taxes associated with the correction of other misstatements identified during fiscal 2018 and other periods. The increase of current liabilities related primarily to a $67.5 million increase of accounts payable that resulted from a misclassification adjustment for amounts previously included as a contra-inventory balance to accounts payable and a $38.6 million increase of accrued expenses. The increase of accrued expenses related to the recognition of a $24.9 million accrued income tax balance associated with the correction of other misstatements identified during fiscal 2018 and other periods, as well as the recognition of $13.7 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. Long-term liabilities decreased primarily as a result of a $32.1 million decrease of long-term deferred tax liabilities related to the correction of other misstatements identified during fiscal 2018 and other periods. The $31.6 million decrease of total equities related primarily to the impacts associated with the $20.6 million net impact on income tax accounts and the recognition of an additional $13.7 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. As of November 30, 2016 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $145.5 million reduction of total assets, a $47.0 million reduction of current liabilities, a $15.5 million increase of long-term liabilities and a $114.0 million reduction of total equities. The reduction of total assets related primarily to the elimination of $141.0 million of current derivative assets that had been incorrectly recorded as assets on the Consolidated Balance Sheet and an approximate $16.0 million reduction of goodwill associated with a goodwill impairment charge recorded during fiscal 2015. The decreases of total assets were partially offset by related adjustments, including a $4.0 million increase of receivables, a $5.7 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $0.9 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $35.0 million reduction of current derivative liabilities and a $20.7 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. These decreases of current liabilities were partially offset by an $8.7 million increase of accounts payable. The increase of long-term liabilities resulted from a $15.5 million increase of long-term deferred tax liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $73.3 million reduction of total assets, an $85.4 million reduction of current liabilities and a $12.1 million increase of total equities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. The misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $63.9 million increase of total assets, a $74.6 million increase of current liabilities, a $0.9 million decrease of long-term liabilities and a $9.9 million decrease of total equities. The increase of total assets related primarily to a misclassification adjustment for $73.8 million previously included as a contra-inventory balance moving to accounts payable. The increased inventories were partially offset by a $48.2 million reduction of inventory related to a misclassification adjustment for certain collateral moving from inventory to receivables. The increase of total liabilities relates primarily to a misclassification adjustment for $73.8 million previously included as a contra-inventory balance moving to accounts payable. The $9.9 million decrease of total equities relates primarily to the $28.8 million net impact on income tax accounts and the recognition of $8.1 million of accrued expense related to the use of a unit of measure assumption in the calculation of an excise tax credit that was changed during fiscal 2018. The overall decrease in total equities was partially offset by an increase that arose from a $27.9 million timing difference for the accrual of dividends and equities payable. CHS INC.

The reduction of total assets related primarily to the elimination of $179.3 million of current derivative assets which had been incorrectly recorded as assets on the Consolidated Balance Sheet and an approximate $16.0 million impairment of goodwill which was triggered when earnings were lowered due to the restatement. The decrease of total assets was partially offset by a related adjustment to increase prepaid income taxes by $9.7 million as a result of the income tax impact of the freight misstatement. The decrease of total current liabilities related primarily to a $7.1 million reduction of current derivative liabilities and a $19.7 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement. The increase of long-term liabilities was primarily attributable to the $28.9 million increase of long-term deferred tax liabilities. The decrease of total equities was related primarily to the elimination of derivative assets and liabilities from the Consolidated Balance Sheet as described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $5.6 million reduction of total assets and a $5.6 million reduction of current liabilities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes. These misclassification adjustments arose primarily due to the application of differing accounting policies between businesses and collectively with the income tax adjustments resulted in a $108.0 million increase of total assets, a $153.1 million increase of current liabilities, a $35.4 million decrease of long-term liabilities and a $9.7 million decrease of total equities. The increase of total assets related primarily to a $28.8 million increase of cash that resulted from a timing difference for the application of in-transit cash and a $78.2 million increase of receivables and notes payable related to a participation arrangement that did not meet certain criteria for off-balance sheet treatment. As a result, both receivables and notes payable were increased by $78.2 million . The increase of current liabilities related primarily to the $78.2 million increase of receivables and notes payable in a participation arrangement that did not meet certain criteria for off-balance sheet treatment, a $29.1 million increase of customer advance payments that resulted from a timing difference related to the application of in-transit cash and a $27.9 million increase of accounts payable that had previously been included as a contra-inventory balance. Long-term liabilities decreased primarily due to the recognition of long-term deferred tax liabilities of $35.1 million related to the correction of other misstatements identified during fiscal 2018 and other periods. The $9.7 million decrease of total equities relates primarily to the $14.1 million net impact on income tax accounts, which was partially offset by a $4.5 million increase related to the valuation of crack spread derivatives. As of February 28, 2017 Freight derivatives and related misstatements (a) The correction of freight derivatives and related misstatements resulted in a $160.3 million reduction of total assets, a $61.3 million reduction of current liabilities, a $15.8 million increase of long-term liabilities and a $114.7 million reduction of total equities. The reduction of total assets related primarily to the elimination of $153.0 million of current derivative assets that were incorrectly recorded as assets on the Consolidate Balance Sheet and an approximate $16.0 million impairment of goodwill recorded in fiscal 2015 associated with lower earnings as a result of the restatement. The overall decrease of total assets was partially offset by related adjustments, including a $6.4 million increase of prepaid income taxes resulting from the income tax impact of the freight misstatement and the recognition of a $0.6 million prepaid freight capacity balance. The decrease of total current liabilities related primarily to a $43.0 million reduction of current derivative liabilities and a $20.7 million reduction of income taxes payable resulting from the income tax effect of the freight misstatement, which were partially offset by the recognition of a $2.3 million accounts payable balance. The increase of long-term liabilities resulted from the $15.8 million increase of long-term deferred tax liabilities. The decrease of total equities related primarily to the elimination of the derivative assets and liabilities described above and the related income tax impacts, as well as the reduction of goodwill associated with the goodwill impairment charge recorded during fiscal 2015. Intercompany misstatements (b) The correction of intercompany misstatements resulted in a $4.9 million reduction of total assets and a $4.9 million reduction of current liabilities due to different practices of eliminating intercompany balances between CHS's businesses which existed in previous periods. Other misstatements (c) Adjustments for other misstatements related primarily to misclassifications between line items included within the Consolidated Balance Sheets, as well as the impact of income tax adjustments on income tax accounts, including prepaid income taxes, income taxes payable and deferred income taxes.
