Basis Of Presentation, Description Of Business And Summary Of Significant Accounting Policies	1. BASIS OF PRESENTATION, DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES References to the Company References to “Green Plains” or the “company” in the consolidated financial statements and in these notes to the consolidated financial statements refer to Green Plains Inc., an Iowa corporation, and its subsidiaries. Consolidated Financial Statements The consolidated financial statements include the company’s accounts and all significant intercompany balances and transactions are eliminated. Unconsolidated entities are included in the financial statements on an equity basis. T he company owns a 49.0 % limited partner interest and a 2.0 % general partner interest in Green Plains Partners LP. Public investors own the remaining 49.0 % limited partner interest in the partnership. The company determined that the limited partners in the partnership with equity at risk lack the power, through voting rights or similar rights, to direct the activities that most significantly impact partnership’s economic performance; therefore, the partnership is considered a variable interest entity. The company, through its ownership of the general partner interest in the partnership, has the power to direct the activities that most significantly affect economic performance and is obligated to absorb losses and has the right to receive benefits that could be significant to the partnership. Therefore, the company is considered the primary beneficiary and consolidates the partnership in the company’s financial statements. The assets of the partnership cannot be used by the company for general corporate purposes. The partnership’s consolidated total assets as of June 30, 2020 and December 31, 2019, excluding intercompany balances, are $ 89.1 million and $ 90.0 million, respectively, and primarily consist of property and equipment, operating lease right-of-use assets and goodwill. The partnership’s consolidated total liabilities as of June 30, 2020 and December 31, 2019, excluding intercompany balances, are $ 174.1 million and $ 180.9 million, respectively, which primarily consist of long-term debt as discussed in Note 9 – Debt and operating lease liabilities. The liabilities recognized as a result of consolidating the partnership do not represent additional claims on our general assets. GPCC, a previously a wholly owned subsidiary of Green Plains, was disposed of during the third quarter of 2019. After closing, GPCC is no longer consolidated in the company’s consolidated financial statements and the GPCC investment is accounted for using the equity method of accounting. Additionally, the company concluded that the disposition of GPCC met the requirements under ASC 205-20 Presentation of Financial Statements – Discontinued Operations (“ASC 205-20”) to be presented as discontinued operations. As such, GPCC results prior to its disposition are classified as discontinued operations in prior period consolidated financial statements. See Note 3 - Dispositions and Discontinued Operations for further details. The company also owns a 90.0 % interest in BioProcess Algae, a joint venture formed in 2008, and consolidates their results in its consolidated financial statements. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and notes required by GAAP, the consolidated financial statements should be read in conjunction with the company’s annual report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on February 20, 2020. The unaudited financial information reflects adjustments, which are, in the opinion of management, necessary for a fair presentation of results of operations, financial position and cash flows for the periods presented. The adjustments are normal and recurring in nature, unless otherwise noted. Interim period results are not necessarily indicative of the results to be expected for the entire year. Reclassifications Certain prior year amounts relating to the discontinued operations of GPCC were reclassified to conform to the current year presentation. These reclassifications affected certain balance sheet line items, total revenues, costs and expenses. Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The company bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances and regularly evaluates the appropriateness of its estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including but not limited to those relating to revenue recognition, operating leases, impairment of long-lived assets and goodwill, derivative financial instruments and accounting for income taxes, are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements. Description of Business The company operates within four business segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services. Cash and Cash Equivalents Cash and cash equivalents includes bank deposits as well as short-term, highly liquid investments with original maturities of three months or less. Restricted Cash The company has restricted cash, which can only be used for funding letters of credit or for payment towards a revolving credit agreement. Restricted cash also includes cash margins and securities pledged to commodity exchange clearinghouses and at times, funds in escrow related to acquisition and disposition activities. To the degree these segregated balances are cash and cash equivalents, they are considered restricted cash on the consolidated balance sheets. Revenue Recognition The company recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing services. Sales, value add, and other taxes the company collects concurrent with revenue-producing activities are excluded from revenue. Sales of ethanol, distillers grains, corn oil, natural gas and other commodities by the company’s marketing business are recognized when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenues related to marketing for third parties are presented on a gross basis as the company controls the product prior to the sale to the end customer, takes title of the product and has inventory risk. Unearned revenue is recorded for goods in transit when the company has received payment but control has not yet been transferred to the customer. Revenues for receiving, storing, transferring and transporting ethanol and other fuels are recognized when the product is delivered to the customer. The company routinely enters into physical-delivery energy commodity purchase and sale agreements. At times, the company settles these transactions by transferring its obligations to other counterparties rather than delivering the physical commodity. Energy trading transactions are reported net as a component of revenue. Revenues include net gains or losses from derivatives related to products sold while cost of goods sold includes net gains or losses from derivatives related to commodities purchased. Revenues also include realized gains and losses on related derivative financial instruments and reclassifications of realized gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Sales of products, including agricultural commodities, are recognized when control of the product is transferred to the customer, which depends on the agreed upon shipment or delivery terms. Revenues related to grain merchandising are presented gross and include shipping and handling, which is also a component of cost of goods sold. Revenues from grain storage are recognized over time as the services are rendered. A substantial portion of the partnership revenues are derived from fixed-fee commercial agreements for storage, terminal or transportation services. The partnership recognizes revenue upon transfer of control of product from its storage tanks and fuel terminals, when railcar volumetric capacity is provided, and as truck transportation services are performed. To the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred. Shipping and Handling Costs The company accounts for shipping and handling activities related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, the company records customer payments associated with shipping and handling costs as a component of revenue, and classifies such costs as a component of cost of goods sold. Cost of Goods Sold Cost of goods sold includes direct labor, materials, shipping and plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in ethanol production. Grain purchasing and receiving costs, excluding labor costs for grain buyers and scale operators, are also included in cost of goods sold. Materials include the cost of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs, as well as reclassifications of gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Plant overhead consists primarily of plant utilities, repairs and maintenance and outbound freight charges. Shipping costs incurred by the company, including railcar costs, are also reflected in cost of goods sold. The company uses exchange-traded futures and options contracts and forward purchase and sale contracts to attempt to minimize the effect of price changes on ethanol, grain and natural gas. Exchange-traded futures and options contracts are valued at quoted market prices and settled predominantly in cash. The company is exposed to loss when counterparties default on forward purchase and sale contracts. Grain inventories held for sale and forward purchase and sale contracts are valued at market prices when available or other market quotes adjusted for differences, primarily in transportation, between the exchange-traded market and local market where the terms of the contract is based. Changes in forward purchase contracts and exchange-traded futures and options contracts are recognized as a component of cost of goods sold. Operations and Maintenance Expenses In the partnership segment, transportation expenses represent the primary component of operations and maintenance expenses. Transportation expenses include railcar leases, freight and shipping of the company’s ethanol and co-products, as well as costs incurred storing ethanol at destination terminals. Derivative Financial Instruments The company uses various derivative financial instruments, including exchange-traded futures and exchange-traded and over-the-counter options contracts, to attempt to minimize risk and the effect of commodity price changes including but not limited to, corn, ethanol, natural gas and crude oil. The company monitors and manages this exposure as part of its overall risk management policy to reduce the adverse effect market volatility may have on its operating results. The company may hedge these commodities as one way to mitigate risk; however, there may be situations when these hedging activities themselves result in losses. By using derivatives to hedge exposures to changes in commodity prices, the company is exposed to credit and market risk. The company’s exposure to credit risk includes the counterparty’s failure to fulfill its performance obligations under the terms of the derivative contract. The company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring their financial condition. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The company manages market risk by incorporating parameters to monitor exposure within its risk management strategy, which limits the types of derivative instruments and strategies the company can use and the degree of market risk it can take using derivative instruments. The company evaluates its physical delivery contracts to determine if they qualify for normal purchase or sale exemptions which are expected to be used or sold over a reasonable period in the normal course of business. Contracts that do not meet the normal purchase or sale criteria are recorded at fair value. Changes in fair value are recorded in operating income unless the contracts qualify for, and the company elects, cash flow hedge accounting treatment. Certain qualifying derivatives related to ethanol production and agribusiness and energy services are designated as cash flow hedges. The company evaluates the derivative instrument to ascertain its effectiveness prior to entering into cash flow hedges. Unrealized gains and losses are reflected in accumulated other comprehensive income or loss until the gain or loss from the underlying hedged transaction is realized and the physical transaction is completed. When it becomes probable a forecasted transaction will not occur, the cash flow hedge treatment is discontinued, which affects earnings. These derivative financial instruments are recognized in current assets or current liabilities at fair value. At times, the company hedges its exposure to changes in inventory values and designates qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted in the current period for changes in fair value. Ineffectiveness of the hedges is recognized in the current period to the extent the change in fair value of the inventory is not offset by the change in fair value of the derivative. Recent Accounting Pronouncements In December 2019, the FASB issued amended guidance in ASC 740, Income Taxes - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 74 0. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The company is evaluating the impact of this standard on its consolidated financial statements.

Revenue [Abstract]
Revenue	2. REVENUE Revenue Recognition Revenue is recognized when obligations under the terms of a contract with a customer are satisfied. Generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing services. Sales, value add, and other taxes the company collects concurrent with revenue-producing activities are excluded from revenue. Revenue by Source The following tables disaggregate revenue by major source for the three and six months ended June 30, 2020 and 2019 (in thousands): Three Months Ended June 30, 2020 Ethanol Production Agribusiness & Energy Services Food & Ingredients Partnership Eliminations Total Revenues: Revenues from contracts with customers under ASC 606: Ethanol $ - $ - $ - $ - $ - $ - Distillers grains 4,589 - - - - 4,589 Service revenues - - - 1,267 - 1,267 Other 1,232 1,870 - - - 3,102 Intersegment revenues 25 - - 1,838 ( 1,863 ) - Total revenues from contracts with customers 5,846 1,870 - 3,105 ( 1,863 ) 8,958 Revenues from contracts accounted for as derivatives under ASC 815 (1) : Ethanol 218,816 90,907 - - - 309,723 Distillers grains 55,635 13,555 - - - 69,190 Corn oil 9,504 12,146 - - - 21,650 Grain - 7,724 - - - 7,724 Other 741 ( 114 ) - - - 627 Intersegment revenues - 4,368 - - ( 4,368 ) - Total revenues from contracts accounted for as derivatives 284,696 128,586 - - ( 4,368 ) 408,914 Leasing revenues under ASC 842 (2) : - - - 17,276 ( 17,159 ) 117 Total Revenues $ 290,542 $ 130,456 $ - $ 20,381 $ ( 23,390 ) $ 417,989 Six Months Ended June 30, 2020 Ethanol Production Agribusiness & Energy Services Food & Ingredients Partnership Eliminations Total Revenues: Revenues from contracts with customers under ASC 606: Ethanol $ - $ - $ - $ - $ - $ - Distillers grains 21,064 - - - - 21,064 Service revenues - - - 2,446 - 2,446 Other 4,191 2,260 - - - 6,451 Intersegment revenues 50 - - 3,912 ( 3,962 ) - Total revenues from contracts with customers 25,305 2,260 - 6,358 ( 3,962 ) 29,961 Revenues from contracts accounted for as derivatives under ASC 815 (1) : Ethanol 585,908 217,000 - - - 802,908 Distillers grains 128,162 18,264 - - - 146,426 Corn oil 24,188 17,876 - - - 42,064 Grain 6 15,674 - - - 15,680 Other 2,698 10,895 - - - 13,593 Intersegment revenues - 11,676 - - ( 11,676 ) - Total revenues from contracts accounted for as derivatives 740,962 291,385 - - ( 11,676 ) 1,020,671 Leasing revenues under ASC 842 (2) : - - - 34,294 ( 34,068 ) 226 Total Revenues $ 766,267 $ 293,645 $ - $ 40,652 $ ( 49,706 ) $ 1,050,858 Three Months Ended June 30, 2019 (3) Ethanol Production Agribusiness & Energy Services Food & Ingredients Partnership Eliminations Total Revenues: Revenues from contracts with customers under ASC 606: Ethanol $ - $ - $ - $ - $ - $ - Distillers grains 13,724 - - - - 13,724 Service revenues - - - 1,608 - 1,608 Other 1,773 442 - - - 2,215 Intersegment revenues 26 - - 1,829 ( 1,855 ) - Total revenues from contracts with customers 15,523 442 - 3,437 ( 1,855 ) 17,547 Revenues from contracts accounted for as derivatives under ASC 815 (1) : Ethanol 355,385 136,225 - - - 491,610 Distillers grains 66,139 9,629 - - - 75,768 Corn oil 12,994 10,463 - - - 23,457 Grain - 19,229 - - - 19,229 Other 902 1,973 - - - 2,875 Intersegment revenues - 7,007 - - ( 7,007 ) - Total revenues from contracts accounted for as derivatives 435,420 184,526 - - ( 7,007 ) 612,939 Leasing revenues under ASC 842 (2) : - - - 17,388 ( 17,304 ) 84 Total Revenues $ 450,943 $ 184,968 $ - $ 20,825 $ ( 26,166 ) $ 630,570 Six Months Ended June 30, 2019 (3) Ethanol Production Agribusiness & Energy Services Food & Ingredients Partnership Eliminations Total Revenues: Revenues from contracts with customers under ASC 606: Ethanol $ 620 $ - $ - $ - $ - $ 620 Distillers grains 31,405 - - - - 31,405 Service revenues - - - 3,691 - 3,691 Other 2,008 620 - - - 2,628 Intersegment revenues 51 - - 3,221 ( 3,272 ) - Total revenues from contracts with customers 34,084 620 - 6,912 ( 3,272 ) 38,344 Revenues from contracts accounted for as derivatives under ASC 815 (1) : Ethanol 556,543 213,302 - - - 769,845 Distillers grains 102,738 26,088 - - - 128,826 Corn oil 21,607 17,434 1,452 - - 40,493 Grain 136 40,084 - - - 40,220 Other 6,668 44,509 - - - 51,177 Intersegment revenues - 12,139 - - ( 12,139 ) - Total revenues from contracts accounted for as derivatives 687,692 353,556 1,452 - ( 12,139 ) 1,030,561 Leasing revenues under ASC 840 (2) : - - - 35,000 ( 34,694 ) 306 Total Revenues $ 721,776 $ 354,176 $ 1,452 $ 41,912 $ ( 50,105 ) $ 1,069,211 (1) Revenues from contracts accounted for as derivatives represent physically settled derivative sales that are outside the scope of ASC 606, where the company recognizes revenue when control of the inventory is transferred within the meaning of ASC 606 as required by ASC 610-20, Gains and Losses from Derecognition of Nonfinancial Assets .

Dispositions And Discontinued Operations [Abstract]
Dispositions And Discontinued Operations	3. DISPOSITIONS AND DISCONTINUED OPERATIONS DISPOSITIONS Disposition of Green Plains Cattle Company LLC On September 1, 2019, the company, TGAM Agribusiness Fund Holdings-B LP (“TGAM”) and StepStone Atlantic Fund, L.P. (“StepStone”) formed a joint venture and entered into the LLC Agreement. GPCC was previously a wholly owned subsidiary of Green Plains. Green Plains also entered into a Securities Purchase Agreement with TGAM and StepStone, whereby TGAM and StepStone purchased an aggregate of 50 % of the membership interests of GPCC from Green Plains for approximately $ 76.9 million in cash. There was no gain or loss recorded as part of this transaction. The LLC Agreement contains certain earn-out or bonus provisions to be paid by or received from GPCC if certain EBITDA thresholds are met. The company will record any gain contingency amounts in the consolidated financial statements when the consideration is received, which is anticipated to be in the third quarter of 2020. Under the LLC Agreement, Green Plains has certain rights and obligations, including but not limited to, the right or obligation: (i) to designate two Managers to the Board of Managers of GPCC (the “Board”), or in the event the size of the Board is increased, the number of Managers equal to two-fifths of the Board, rounded up, and (ii) to fund additional capital contributions in accordance with their percentage interest upon mutual agreement by Green Plains, TGAM and StepStone. Additionally, TGAM and StepStone both have the right or obligation to designate one Manager, or in the event the size of the Board is increased, the number of Managers equal to one-fifths of the Board, rounded up. Each Manager serving on the Board shall have one vote and a majority of the Managers serving on the Board shall constitute a quorum for the transaction of business of the Board. Green Plains’ allocation under the LLC Agreement will be subject to certain adjustments. The assets and liabilities of the GPCC at closing on September 1, 2019 were as follows (in thousands): Amounts of Identifiable Assets Disposed and Liabilities Relinquished Cash $ 2 Accounts receivable, net 17,920 Inventory 387,534 Derivative financial instruments 48,189 Property and equipment 71,678 Other assets 2,291 Current liabilities ( 49,297 ) Short-term notes payable and other borrowings ( 38 ) Current maturities of long-term debt ( 324,028 ) Long-term debt ( 80 ) Other liabilities ( 403 ) Total identifiable net assets disposed $ 153,768 DISCONTINUED OPERATIONS After closing, GPCC is no longer consolidated in the company’s consolidated financial statements and the GPCC investment is accounted for using the equity method of accounting. Additionally, the company concluded that the disposition of GPCC met the requirements under ASC 205-20 . As such, GPCC results prior to its disposition are classified as discontinued operations for all applicable periods. Financial results of GPCC were previously recorded within the food and ingredients segment. Summarized Results of Discontinued Operations The following table presents the results of our discontinued operations (in thousands). Three Months Ended June 30, 2019 (1) Six Months Ended June 30, 2019 (1) Product revenues $ 270,924 $ 478,009 Costs and expenses Cost of goods sold (excluding depreciation and amortization expenses reflected below) 259,900 464,457 Selling, general and administrative expenses 2,176 4,460 Depreciation and amortization expenses 1,583 3,194 Total costs and expenses 263,659 472,111 Operating income 7,265 5,898 Other income (expense) Interest income 63 140 Interest expense ( 4,720 ) ( 9,416 ) Total other expense ( 4,657 ) ( 9,276 ) Income (loss) before income taxes 2,608 ( 3,378 ) Income tax benefit (expense) ( 669 ) 848 Net income (loss) $ 1,939 $ ( 2,530 ) (1) Product revenues, costs of goods sold and selling, general and administrative expenses include certain revenue and expense items which were previously considered intercompany transactions prior to the disposition of GPCC and therefore eliminated upon consolidation. These revenue transactions total $ 5.7 million and $ 9.1 million for the three and six months ended June 30, 2019, respectively. These costs of goods sold transactions total $ 5.6 million and $ 9.0 million for the three and six months ended June 30, 2019, respectively.

Fair Value Disclosures [Abstract]
Fair Value Disclosures	4 . FAIR VALUE DISCLOSURES The following methods, assumptions and valuation techniques were used in estimating the fair value of the company’s financial instruments: Level 1 – unadjusted quoted prices in active markets for identical assets or liabilities the company can access at the measurement date. Level 2 – directly or indirectly observable inputs such as quoted prices for similar assets or liabilities in active markets other than quoted prices included within Level 1, quoted prices for identical or similar assets in markets that are not active, and other inputs that are observable or can be substantially corroborated by observable market data through correlation or other means. Grain inventories held for sale in the agribusiness and energy services segment are valued at nearby futures values, plus or minus nearby basis. Level 3 – unobservable inputs that are supported by little or no market activity and comprise a significant component of the fair value of the assets or liabilities. The company currently does not have any recurring Level 3 financial instruments. Derivative contracts include exchange-traded commodity futures and options contracts and forward commodity purchase and sale contracts. Exchange-traded futures and options contracts are valued based on unadjusted quoted prices in active markets and are classified in Level 1. The majority of the company’s exchange-traded futures and options contracts are cash-settled on a daily basis. There have been no changes in valuation techniques and inputs used in measuring fair value. The company’s assets and liabilities by level are as follows (in thousands): Fair Value Measurements at June 30, 2020 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Level 1) (Level 2) Total Assets: Cash and cash equivalents $ 163,362 $ - $ 163,362 Restricted cash 20,234 - 20,234 Inventories carried at market - 26,572 26,572 Unrealized gains on derivatives - 18,714 18,714 Other assets 112 3,002 3,114 Total assets measured at fair value $ 183,708 $ 48,288 $ 231,996 Liabilities: Accounts payable (1) $ - $ 25,347 $ 25,347 Unrealized losses on derivatives - 11,463 11,463 Other - 13 13 Total liabilities measured at fair value $ - $ 36,823 $ 36,823 Fair Value Measurements at December 31, 2019 Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs (Level 1) (Level 2) Total Assets: Cash and cash equivalents $ 245,977 $ - $ 245,977 Restricted cash 23,919 - 23,919 Inventories carried at market - 73,318 73,318 Unrealized gains on derivatives - 14,515 14,515 Other assets 113 - 113 Total assets measured at fair value $ 270,009 $ 87,833 $ 357,842 Liabilities: Accounts payable (1) $ - $ 37,294 $ 37,294 Unrealized losses on derivatives - 7,771 7,771 Total liabilities measured at fair value $ - $ 45,065 $ 45,065 (1) Accounts payable is generally stated at historical amounts with the exception of $ 25.3 million and $ 37.3 million at June 30, 2020 and December 31, 2019, respectively, related to certain delivered inventory for which the payable fluctuates based on changes in commodity prices. These payables are hybrid financial instruments for which the company has elected the fair value option. The fair value of the company’s debt was approximately $ 520.7 million compared with a book value of $ 509.3 million at June 30, 2020. The fair value of the company’s debt approximated book value, which was $ 564.4 million at December 31, 2019. The company estimated the fair value of its outstanding debt using Level 2 inputs. The company believes the fair values of its accounts receivable approximated book value, which was $ 67.2 million and $ 107.2 million at June 30, 2020 and December 31, 2019, respectively. Although the company currently does not have any recurring Level 3 financial measurements, the fair values of tangible assets and goodwill acquired and the equity component of convertible debt represent Level 3 measurements which were derived using a combination of the income approach, market approach and cost approach for the specific assets or liabilities being valued.

Segment Information

Segment Information [Abstract]
Segment Information	5. SEGMENT INFORMATION The company reports the financial and operating performance for the following four operating segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services. Corporate activities include selling , general and administrative expenses, consisting primarily of compensation, professional fees and overhead costs not directly related to a specific operating segment. During the normal course of business, the operating segments conduct business with each other. For example, the agribusiness and energy services segment procures grain and natural gas and sells products, including ethanol, distillers grains and corn oil for the ethanol production segment. The partnership segment provides fuel storage and transportation services for the ethanol production segment. These intersegment activities are treated like third-party transactions with origination, marketing and storage fees charged at estimated market values. Consequently, these transactions affect segment performance; however, they do not impact the company’s consolidated results since the revenues and corresponding costs are eliminated. The following tables set forth certain financial data for the company’s operating segments (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 (1) 2020 2019 (1) Revenues: Ethanol production: Revenues from external customers $ 290,517 $ 450,917 $ 766,217 $ 721,725 Intersegment revenues 25 26 50 51 Total segment revenues 290,542 450,943 766,267 721,776 Agribusiness and energy services: Revenues from external customers 126,088 177,961 281,969 342,037 Intersegment revenues 4,368 7,007 11,676 12,139 Total segment revenues 130,456 184,968 293,645 354,176 Food and ingredients: Revenues from external customers - - - 1,452 Intersegment revenues - - - - Total segment revenues - - - 1,452 Partnership: Revenues from external customers 1,384 1,692 2,672 3,997 Intersegment revenues 18,997 19,133 37,980 37,915 Total segment revenues 20,381 20,825 40,652 41,912 Revenues including intersegment activity 441,379 656,736 1,100,564 1,119,316 Intersegment eliminations ( 23,390 ) ( 26,166 ) ( 49,706 ) ( 50,105 ) Revenues as reported $ 417,989 $ 630,570 $ 1,050,858 $ 1,069,211 (1) Revenues include certain items which were previously considered intercompany transactions prior to the disposition of GPCC and therefore eliminated upon consolidation.

Inventories [Abstract]
Inventories	6. INVENTORIES Inventories are carried at the lower of cost or net realizable value, except grain held for sale and fair-value hedged inventories. Commodities held for sale are reported at market value. There was no lower of cost or net realizable value inventory adjustment as of June 30, 2020. As of December 31, 2019, the company recorded a $ 6.6 million lower of cost or net realized value inventory adjustment reflected in cost of goods sold within the ethanol production segment.

Goodwill [Abstract]
Goodwill	7. GOODWILL The company had two reporting units, to which goodwill was assigned. We are required to perform impairment tests related to our goodwill annually, which we perform as of October 1, or sooner if an indicator of impairment occurs. Near term industry outlook due to the significant decrease in crude oil prices, lower gasoline demand, general uncertainty due to the COVID-19 outbreak and the subsequent decline in our stock price caused a decline in the company’s market capitalization during the three months ended March 31, 2020. As such, the company determined a triggering event had occurred that required an interim impairment assessment for its ethanol production reporting unit. Due to the impairment indicators noted as a result of these triggering events, we evaluated our goodwill as of March 31, 2020. Significant assumptions inherent in the valuation methodologies for goodwill were employed and included, but were not limited to, prospective financial information, growth rates, discount rates, inflationary factors, and cost of capital. Based on our quantitative evaluation, we determined that the fair value of the ethanol production reporting unit did not exceed its carrying value. As a result, we concluded that the goodwill assigned to the ethanol production reporting unit was impaired and recorded a non-cash impairment charge of $ 24.1 million. Based on similar factors as noted above, the company determined a triggering event had occurred that required an interim impairment assessment for its partnership reporting unit. Due to the impairment indicators noted as a result of these triggering events, we evaluated goodwill as of June 30, 2020. Significant assumptions inherent in the valuation methodologies for goodwill are employed and include, but are not limited to, prospective financial information, growth rates, discount rates, inflationary factors, and cost of capital. Based on the company’s quantitative evaluation of the partnership’s goodwill as of June 30, 2020, it was determined that the fair value of the partnership reporting unit exceeded its carrying value. As a result, the company concluded that the goodwill assigned to the partnership reporting unit was not impaired, but could be at risk of future impairment. Changes in the carrying amount of goodwill attributable to each business segment during the six months ended June 30, 2020 were as follows (in thousands): Ethanol Production Partnership Total Balance, December 31, 2019 $ 24,091 $ 10,598 $ 34,689 Impairment charge ( 24,091 ) - ( 24,091 ) Balance, June 30, 2020 $ - $ 10,598 $ 10,598

Derivative Financial Instruments	8. DERIVATIVE FINANCIAL INSTRUMENTS At June 30, 2020, the company’s consolidated balance sheet reflected unrealized gains of $ 12.8 million, net of tax, in accumulated other comprehensive income which primarily related to our share of equity method investees other comprehensive income. The company expects these gains will be reclassified as income from equity method investees, net of income taxes over the next 12 months as a result of hedged transactions that are forecasted to occur. The amount realized in income from equity method investees, net of income taxes will differ as commodity prices change.

The 4.00 % notes are senior, unsecured obligations of the company, with interest payable on January 1 and July 1 of each year, beginning January 1, 2020, at a rate of 4.00 % per annum. The 4.00 % notes will mature on July 1, 2024 , unless earlier converted, redeemed or repurchased. The 4.00 % notes will be convertible, at the option of the holders, into consideration consisting of, at the company’s election, cash, shares of the company’s common stock, or a combination of cash and shares of the company’s common stock until the close of business on the scheduled trading day immediately preceding the maturity date. However, before January 1, 2024, the 4.00 % notes will not be convertible unless certain conditions are satisfied. The initial conversion rate is 64.1540 shares of common stock per $ 1,000 of principal, which is equal to a conversion price of approximately $ 15.59 per share. The conversion rate will be subject to adjustment upon the occurrence of certain events. In addition, the company may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including the company’s calling the 4.00 % notes for redemption. On and after July 1, 2022, and prior to the maturity date, the company may redeem all, but not less than all, of the 4.00 % notes for cash if the sale price of the company’s common stock equals or exceeds 140 % of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the company delivers notice of the redemption. The redemption price will equal 100 % of the principal amount of the 4.00 % notes to be redeemed, plus any accrued and unpaid interest to, but excluding, the redemption date. In addition, upon the occurrence of a fundamental change, holders of the 4.00 % notes will have the right, at their option, to require the company to repurchase the 4.00 % notes in cash at a price equal to 100 % of the principal amount of the 4.00 % notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In August 2016, the company issued $ 170.0 million of 4.125 % convertible senior notes due in 2022, or the 4.125 % notes. The 4.125 % notes are senior, unsecured obligations of the company, with interest payable on March 1 and September 1 of each year. The company may settle the 4.125 % notes in cash, common stock or a combination of cash and common stock. Prior to March 1, 2022, the 4.125 % notes are not convertible unless certain conditions are satisfied. The initial conversion rate is 35.7143 shares of common stock per $ 1,000 of principal, which is equal to a conversion price of approximately $ 28.00 per share. The conversion rate is subject to adjustment upon the occurrence of certain events, including upon redemption of the 4.125 % notes. The company may redeem all, but not less than all, of the 4.125 % notes at any time on or after September 1, 2020, if the company’s common stock equals or exceeds 140 % of the applicable conversion price for a specified time period ending on the trading day immediately prior to the date the company delivers notice of the redemption. The redemption price will equal 100 % of the principal plus any accrued and unpaid interest. Holders of the 4.125 % notes have the option to require the company to repurchase the 4.125 % notes in cash at a price equal to 100 % of the principal plus accrued and unpaid interest when there is a fundamental change, such as change in control. If an event of default occurs, it could result in the 4.125 % notes being declared due and payable. Ethanol Production Segment The company has small equipment financing loans, finance leases on equipment or facilities, and other forms of debt financing. Agribusiness and Energy Services Segment Green Plains Trade has a $ 300.0 million senior secured asset-based revolving credit facility to finance working capital for marketing and distribution activities based on eligible collateral equal to the sum of percentages of eligible receivables and inventories, less miscellaneous adjustments.

The terms impose affirmative and negative covenants for Green Plains Trade, including maintaining a minimum fixed charge coverage ratio of 1.15 to 1.00. Capital expenditures are limited to $ 1.5 million per year under the credit facility. The credit facility also restricts distributions related to capital stock, with an exception for distributions up to 50 % of net income if, on a pro forma basis, (a) availability has been greater than $ 10.0 million for the last 30 days and (b) the borrower would be in compliance with the fixed charge coverage ratio on the distribution date. Green Plains Grain has a $ 100.0 million senior secured asset-based revolving credit facility, which matures on June 28, 2022 . The credit facility finances working capital up to the maximum commitment based on eligible collateral equal to the sum of percentages of eligible cash, receivables and inventories, less miscellaneous adjustments.

The credit facility also includes an accordion feature that enables the facility to be increased by up to $ 75.0 million with agent approval. The credit facility can also be increased by up to $ 50.0 million for seasonal borrowings. Total commitments outstanding cannot exceed $ 225.0 million. Depending on utilization, the total unused portion of the $ 100.0 million revolving credit facility is also subject to a commitment fee ranging from 0.375 % to 0.50 %. Lenders receive a first priority lien on certain cash, inventory, accounts receivable and other assets owned by Green Plains Grain. The terms impose affirmative and negative covenants for Green Plains Grain, including maintaining minimum working capital to be the greater of (i) $ 18,000,000 and (ii) 18 % of the sum of the then total commitment plus the aggregate seasonal line commitments . Minimum tangible net worth is required to be greater than 21 % of the sum of the then total commitment plus the aggregate seasonal line commitments. The credit facility also requires the company to maintain a maximum annual leverage of 6.00 to 1.00. Capital expenditures are limited to $ 8.0 million per year under the credit facility, plus equity contributions from the company and unused amounts of up to $ 8.0 million from the previous year. In addition, if the company has long-term indebtedness on the date of calculation of greater than $ 10.0 million, the credit facility requires the company to maintain a minimum fixed charge coverage ratio of 1.25 to 1.00 and a maximum long term debt capitalization of 40 %. Green Plains Grain has entered into short-term inventory financing agreements with a financial institution. At June 30, 2020, 2.3 million bushels of corn had been designated as collateral under these agreements at initial values totaling $ 9.0 million. The company has accounted for the agreements as short-term notes, rather than sales, and has elected the fair value option to offset fluctuations in market prices of the inventory. At June 30, 2020, the short-term notes payable were valued at $ 9.5 million and were measured using Level 2 inputs. Green Plains Commodity Management has an uncommitted $ 30.0 million revolving credit facility which matures April 30, 2023 to finance margins related to its hedging programs. Advances are subject to variable interest rates equal to LIBOR plus 1.75 %. Partnership Segment Green Plains Partners has a $ 135.0 million credit facility to fund working capital, capital expenditures and other general partnership purposes. The credit facility was amended on June 4, 2020, decreasing the amount available under the facility from $ 200.0 million to $ 135.0 million. The amended credit facility includes a $ 130.0 million term loan and a $ 5.0 million revolver, and matures on December 31, 2021 . The term loan requires a principal payment of $ 7.5 million on July 15, 2020 and $ 2.5 million in monthly principal payments beginning August 15, 2020, with a step up to monthly payments of $ 3.2 million beginning May 15, 2021. In addition, if at any time subsequent to July 15, 2020, the partnership’s cash balance exceeds $ 2.5 million for more than five consecutive business days, prepayments of outstanding principal are required in an amount equal to the excess cash. The partnership is also required to prepay outstanding principal on the credit facility with 100 % of net cash proceeds from any asset disposition or recovery event. Any prepayments on the term loan are applied to the remaining principal balance in inverse order of maturity, including the final payment. The term loan balance, and any advances on the revolver, are subject to a floating interest rate based on a 1.0% LIBOR floor plus 4.50 % to 5.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. The unused portion of the revolver is also subject to a commitment fee of 0.50 %. As of June 30, 2020, the term loan had a balance of $ 130.0 million and an interest rate of 6.25% and the revolver was unused. The credit facility also allows for swing line loans subject to the revolver availability. Swing line loans are subject to a floating interest rate based on the Prime Rate plus 3.5 % to 4.25 % dependent upon the preceding fiscal quarter’s consolidated leverage ratio. As of June 30, 2020, there were no outstanding swing line loans. The partnership’s obligations under the credit facility are secured by a first priority lien on (i) the equity interests of the partnership’s present and future subsidiaries, (ii) all of the partnership’s present and future personal property, such as investment property, general intangibles and contract rights, including rights under any agreements with Green Plains Trade, and (iii) all proceeds and products of the equity interests of the partnership’s present and future subsidiaries and its personal property and (iv) substantially all of the partnership’s real property and material leases of real property. The terms impose affirmative and negative covenants, including restrictions on the partnership’s ability to incur additional debt, acquire and sell assets, create liens, invest capital, pay distributions and materially amend the partnership’s commercial agreements with Green Plains Trade. The credit facility also requires the partnership to maintain a maximum consolidated leverage ratio, as of the end of any fiscal quarter, of no more than 3.0 x that decreases 0.25 x each quarter to 1.50 x by December 31, 2021, and a minimum consolidated debt service coverage ratio of 1.1 x , each of which is calculated on a pro forma basis with respect to acquisitions and divestitures occurring during the applicable period. The consolidated leverage ratio is calculated by dividing total funded indebtedness by the sum of the four preceding fiscal quarters’ consolidated EBITDA. The consolidated debt service coverage ratio is calculated by taking the sum of the four preceding fiscal quarters’ consolidated EBITDA minus income taxes and consolidated capital expenditures for such period divided by the sum of the four preceding fiscal quarters’ consolidated interest charges plus consolidated scheduled funded debt payments for such period. Under the amended terms of the credit facility, the partnership may make quarterly distribution payments in an aggregate amount not to exceed $ 0.12 per outstanding unit, so long as (i) no default has occurred and is continuing, or would result from payment of the distribution, and (ii) the partnership and its subsidiaries are in compliance with its financial covenants and remain in compliance after payment of the distribution. Covenant Compliance The company was in compliance with its debt covenants as of June 30, 2020. Restricted Net Assets At June 30, 2020, there were approximately $ 66.4 million of net assets at the company’s subsidiaries that could not be transferred to the parent company in the form of dividends, loans or advances due to restrictions contained in the credit facilities of these subsidiaries.

Stock-Based Compensation [Abstract]
Stock-Based Compensation	10. STOCK-BASED COMPENSATION The company had a 2009 Equity Incentive Plan which reserved a total of 4.1 million shares of common stock for issuance pursuant to the plan. On May 6, 2020, the shareholders of the company approved the 2019 Equity Incentive Plan which granted an additional 1.6 million shares for stock-based compensation, including options to purchase shares of common stock, stock appreciation rights tied to the value of common stock, restricted stock, restricted stock unit awards and performance share awards to eligible employees, non-employee directors and consultants. All shares remaining under the 2009 Equity Incentive Plan rolled into the 2019 Equity Incentive Plan effective May 6, 2020. The company measures stock-based compensation at fair value on the grant date, with no adjustments for estimated forfeitures. The company records noncash compensation expense related to equity awards in its consolidated financial statements over the requisite period on a straight-line basis. Restricted Stock Awards and Deferred Stock Units The non-vested stock award and deferred stock unit activity for the six months ended June 30, 2020, is as follows: Non-Vested Shares and Deferred Stock Units Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2019 751,315 $ 17.48 Granted 645,827 9.75 Forfeited ( 20,301 ) 16.26 Vested ( 352,080 ) 18.83 Non-Vested at June 30, 2020 1,024,761 $ 12.17 2.0 Performance Shares On March 18, 2020, the board of directors granted performance shares to be awarded in the form of common stock to certain participants of the plan. These performance shares vest based on the level of achievement of certain performance goals, including the incremental value achieved from the company’s high-protein initiatives, annual production levels and return on investment (ROI). The performance shares were granted at a target of 100 %, but each performance share will reduce or increase depending on results for the performance period. If the company achieves the maximum performance goals, the maximum amount of shares available to be issued pursuant to the 2020 awards are 641,823 performance shares which represents approximately 276 % of the 232,566 performance shares which remain outstanding. The actual number of performance shares that will ultimately vest is based on the actual performance targets achieved at the end of the performance period. On February 19, 2019 and March 19, 2018, the board of directors granted performance shares to be awarded in the form of common stock to certain participants of the plan. These performance shares vest based on the company’s average return on net assets (RONA) and the company’s total shareholder return (TSR), as further described herein. The performance shares vest on the third anniversary of the grant, if the RONA and TSR criteria are achieved and the participant is then employed by the company. Fifty percent of the performance shares vest based upon the company’s ability to achieve a predetermined RONA during the three year performance period. The remaining fifty percent of the performance shares vest based upon the company’s total TSR during the three year performance period relative to that of the company’s performance peer group. The performance shares were granted at a target of 100 %, but each performance share will reduce or increase depending on results for the performance period for the company's RONA, and the company’s TSR relative to that of the performance peer group. If the company’s RONA and TSR achieve the maximum goals, the maximum amount of shares available to be issued pursuant to the 2018 and 2019 awards are 428,104 performance shares or 150 % of the 285,403 performance shares which remain outstanding. The actual number of performance shares that will ultimately vest is based on the actual percentile ranking of the company’s RONA, and the company’s TSR compared to the peer performance at the end of the performance period. The company used the Monte Carlo valuation model to estimate the fair value of the performance shares on the date of the grant. The weighted average assumptions used by the company in applying the Monte Carlo valuation model for performance share grants are illustrated in the following table: FY 2019 Performance Awards FY 2018 Performance Awards Risk-free interest rate 2.45 % 2.44 % Dividend yield 3.13 % 2.64 % Expected volatility 41.69 % 45.11 % Monte Carlo valuation 99.62 % 97.39 % Closing stock price on the date of grant $ 15.34 $ 18.15 The non-vested performance share award activity for the six months ended June 30, 2020, is as follows: Performance Shares Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2019 285,403 $ 16.38 Granted 232,566 10.64 Non-Vested at June 30, 2020 517,969 $ 13.80 2.2 Stock Options The fair value of the stock options is estimated on the date of the grant using the Black - Scholes option - pricing model, a pricing model acceptable under GAAP. The expected life of the options is the period of time the options are expected to be outstanding. The company did no t grant any stock option awards during the six months ended June 30, 2020 and 2019. The activity related to the exercisable stock options for the six months ended June 30, 2020, is as follows: Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (in thousands) Outstanding at December 31, 2019 10,000 $ 16.95 0.2 $ - Expired ( 10,000 ) 16.95 - - Outstanding at June 30, 2020 - $ - - $ - Exercisable at June 30, 2020 - $ - - $ - Green Plains Partners Green Plains Partners has a long-term incentive plan (LTIP) intended to promote the interests of the partnership, its general partner and affiliates by providing unit-based incentive compensation awards to employees, consultants and directors to encourage superior performance. The LTIP reserves 2,500,000 common limited partner units for issuance in the form of options, restricted units, phantom units, distribution equivalent rights, substitute awards, unit appreciation rights, unit awards, profit interest units or other unit-based awards. The partnership measures unit-based compensation at fair value on the grant date, with no adjustments for estimated forfeitures. The partnership records noncash compensation expense related to the awards over the requisite service period on a straight-line basis. The non-vested unit-based awards activity for the six months ended June 30, 2020, is as follows: Non-Vested Shares and Deferred Stock Units Weighted- Average Grant- Date Fair Value Weighted-Average Remaining Vesting Term (in years) Non-Vested at December 31, 2019 22,856 $ 14.00 Vested ( 22,856 ) 14.00 Non-Vested at June 30, 2020 - $ - 0.0 Stock-Based and Unit Based Compensation Expense Compensation costs for stock-based and unit-based payment plans were $ 2.3 million and $ 3.6 million for the three and six months ended June 30, 2020, respectively, and $ 2.3 million and $ 4.8 million for the three and six months ended June 30, 2019. At June 30, 2020, there was $ 13.6 million of unrecognized compensation costs from stock-based and unit-based compensation related to non-vested awards. This compensation is expected to be recognized over a weighted-average period of approximately 2.0 years. The pote ntial tax benefit related to stock-based payment is approximately 24.2 % of these expe nses .

Earnings Per Share

Earnings Per Share	6 Months Ended

Earnings Per Share [Abstract]
Earnings Per Share	11. EARNINGS PER SHARE Basic earnings per share, or EPS, is calculated by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. The company computed diluted EPS by dividing net income on an if-converted basis, adjusted to add back net interest expense related to the convertible debt instruments, by the weighted average number of common shares outstanding during the period, adjusted to include the shares that would be issued if the convertible debt instruments were converted to common shares and the effect of any outstanding dilutive securities. In addition, due to the presentation of GPCC as discontinued operations, the company has presented basic and diluted earnings per share from both continuing operations and from discontinued operations. The basic and diluted EPS are calculated as follows (in thousands, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2020 2019 2020 2019 Numerator: Net loss from continuing operations (1) $ ( 8,214 ) $ ( 47,281 ) $ ( 24,659 ) $ ( 85,611 ) Net income (loss) from discontinued operations - 1,939 - ( 2,530 ) Net loss attributable to Green Plains $ ( 8,214 ) $ ( 45,342 ) $ ( 24,659 ) $ ( 88,141 ) Denominator: Weighted-average shares outstanding - basic 34,603 40,081 34,634 40,200 Dilutive effect of convertible debt and stock-based compensation (2) - - - - Weighted-average shares outstanding - diluted 34,603 40,081 34,634 40,200 EPS - basic and diluted: EPS from continuing operations $ ( 0.24 ) $ ( 1.18 ) $ ( 0.71 ) $ ( 2.13 ) EPS from discontinued operations - 0.05 - ( 0.06 ) EPS $ ( 0.24 ) $ ( 1.13 ) $ ( 0.71 ) $ ( 2.19 ) Anti-dilutive weighted-average convertible debt and stock-based compensation (2) 14,074 7,404 13,994 7,041 (1) Net loss from continuing operations can be recalculated from our consolidated statements of operations by taking the net loss from continuing operations including noncontrolling interest less net income attributable to noncontrolling interests.

Income Taxes

Income Taxes	6 Months Ended

Income Taxes [Abstract]
Income Taxes	13. INCOME TAXES The company records actual income tax expense or benefit during interim periods rather than on an annual effective tax rate method. Certain items are given discrete period treatment and the tax effect of those items are reported in full in the relevant interim period. Green Plains Partners is a limited partnership, which is treated as a flow-through entity for federal income tax purposes and is not subject to federal income taxes. As a result, the consolidated financial statements do not reflect income taxes on pre-tax income or loss attributable to the noncontrolling interest in the partnership. The CARES Act was signed into law on March 27, 2020. The CARES Act includes several significant business tax provisions including elimination of the taxable limit for certain net operating losses (“NOL”), allowing businesses to carry back NOLs arising in 2018, 2019 and 2020 to the five prior tax years, accelerating refunds of previously generated corporate AMT credits , and loosening the business interest limitation under §163(j) from 30 % to 50 %. The CARES Act also contains an employee retention credit to encourage employers to maintain headcounts even if employees cannot report to work because of issues related to the COVID-19. In the second quarter, the company filed its preliminary 2019 federal income tax return, as well as a refund claim with the IRS to carry back our 2019 NOL to prior years. The company recorded an additional income tax benefit of approximately $ 5.5 million during the second quarter related to the CARES Act in addition to adjustments to certain valuation allowances. In the first quarter the company recorded an income tax benefit related to the expected NOL carry back claim of $ 28.4 million which was an estimate based on the amount of NOL rated to the 2019 year-end tax provision. The company recorded income tax benefit of $ 11.5 million and $ 55.7 million for the three and six months ended June 30, 2020, compared with $ 15.3 million and $ 28.3 million for the same periods in 2019. The decrease in the amount of income tax benefit recorded for the three months ended June 30, 2020 as compared to the same period in 2019 was primarily due to an increase in pretax income offset by the tax benefit for the utilization of previously recorded tax NOLs in the three month period ended June 30, 2020 as allowed under the provisions of the recently enacted CARES Act. The increase in the amount of the tax benefit recorded for the six months ended June 30, 2020 compared to the same period in 2019 was to record the tax benefit associated with the carry back of the tax NOL generated in 2019 to the 2014 tax year under the newly enacted CARES Act, as well as the release of a previously recorded valuation allowance against the 2019 NOL and other deferred tax assets. The amount of unrecognized tax benefits for uncertain tax positions was $ 51.6 million as of June 30, 2020 and December 31, 2019. The 2020 effective tax rate can be affected by variances in the estimates and amounts of taxable income among the various states, entities and activity types, realization of tax credits, adjustments from resolution of tax matters under review, valuation allowances and the company’s assessment of its liability for uncertain tax positions.

Equity Method Investments [Abstract]
Equity Method Investments	16. EQUITY METHOD INVESTMENTS Green Plains Cattle Company LLC On September 9, 2019, Green Plains, TGAM and StepStone announced the formation of a joint venture. Such parties entered into the Second Amended and Restated Limited Liability Company Agreement of GPCC effective as of September 1, 2019. GPCC was previously a wholly owned subsidiary of Green Plains. Green Plains also entered into a Securities Purchase Agreement with TGAM and StepStone, whereby TGAM and StepStone purchased an aggregate of 50 % of the membership interests of GPCC from Green Plains. After closing, GPCC is no longer consolidated in the company’s consolidated financial statements and the GPCC investment is accounted for using the equity method of accounting. GPCC results prior to its disposition are classified as discontinued operations in our current and prior period financials. The GPCC investment is accounted for using the equity method of accounting. GPCC conducts the business of the joint venture, including (i) owning and operating the cattle feeding operations (as defined below), and (ii) any other activities approved by GPCC’s board of managers. GPCC continues to have the capacity to support 355,000 head of cattle and has approximately 11.7 million bushels of grain storage capacity. Historical GPCC operational results prior to its disposition are recorded as discontinued operations in the consolidated statement of operations. The company does not consolidate any part of the assets or liabilities or operating results of its equity method investee. The company’s share of net income or loss in the investee increases or decreases, as applicable, the carrying value of the investment. With respect to GPCC, the company determined that this entity does not represent a variable interest entity and consolidation is not required. In addition, although the company has the ability to exercise significant influence over the joint venture through board representation and voting rights, all significant decisions require the consent of the other investors without regard to economic interest. Summarized Financial Information Our equity method investments are summarized in the following table (in thousands): Ownership as of June 30, 2020 June 30, 2020 December 31, 2019 Green Plains Cattle Company LLC (1) 50 % $ 110,101 $ 64,161 Other Various 3,662 4,837 Total $ 113,763 $ 68,998 (1) The equity method investment in GPCC is impacted by the effect of deferred gains or losses on cattle sale contracts designated in a cash flow hedge relationship.

Basis Of Presentation, Description Of Business And Summary Of Significant Accounting Policies [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements The consolidated financial statements include the company’s accounts and all significant intercompany balances and transactions are eliminated. Unconsolidated entities are included in the financial statements on an equity basis. T he company owns a 49.0 % limited partner interest and a 2.0 % general partner interest in Green Plains Partners LP. Public investors own the remaining 49.0 % limited partner interest in the partnership. The company determined that the limited partners in the partnership with equity at risk lack the power, through voting rights or similar rights, to direct the activities that most significantly impact partnership’s economic performance; therefore, the partnership is considered a variable interest entity. The company, through its ownership of the general partner interest in the partnership, has the power to direct the activities that most significantly affect economic performance and is obligated to absorb losses and has the right to receive benefits that could be significant to the partnership. Therefore, the company is considered the primary beneficiary and consolidates the partnership in the company’s financial statements. The assets of the partnership cannot be used by the company for general corporate purposes. The partnership’s consolidated total assets as of June 30, 2020 and December 31, 2019, excluding intercompany balances, are $ 89.1 million and $ 90.0 million, respectively, and primarily consist of property and equipment, operating lease right-of-use assets and goodwill. The partnership’s consolidated total liabilities as of June 30, 2020 and December 31, 2019, excluding intercompany balances, are $ 174.1 million and $ 180.9 million, respectively, which primarily consist of long-term debt as discussed in Note 9 – Debt and operating lease liabilities. The liabilities recognized as a result of consolidating the partnership do not represent additional claims on our general assets. GPCC, a previously a wholly owned subsidiary of Green Plains, was disposed of during the third quarter of 2019. After closing, GPCC is no longer consolidated in the company’s consolidated financial statements and the GPCC investment is accounted for using the equity method of accounting. Additionally, the company concluded that the disposition of GPCC met the requirements under ASC 205-20 Presentation of Financial Statements – Discontinued Operations (“ASC 205-20”) to be presented as discontinued operations. As such, GPCC results prior to its disposition are classified as discontinued operations in prior period consolidated financial statements. See Note 3 - Dispositions and Discontinued Operations for further details. The company also owns a 90.0 % interest in BioProcess Algae, a joint venture formed in 2008, and consolidates their results in its consolidated financial statements. The accompanying unaudited consolidated financial statements are prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Because they do not include all of the information and notes required by GAAP, the consolidated financial statements should be read in conjunction with the company’s annual report on Form 10-K for the year ended December 31, 2019, as filed with the SEC on February 20, 2020. The unaudited financial information reflects adjustments, which are, in the opinion of management, necessary for a fair presentation of results of operations, financial position and cash flows for the periods presented. The adjustments are normal and recurring in nature, unless otherwise noted. Interim period results are not necessarily indicative of the results to be expected for the entire year.
Reclassifications	Reclassifications Certain prior year amounts relating to the discontinued operations of GPCC were reclassified to conform to the current year presentation. These reclassifications affected certain balance sheet line items, total revenues, costs and expenses.
Use Of Estimates In The Preparation Of Consolidated Financial Statements	Use of Estimates in the Preparation of Consolidated Financial Statements The preparation of consolidated financial statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. The company bases its estimates on historical experience and assumptions it believes are proper and reasonable under the circumstances and regularly evaluates the appropriateness of its estimates and assumptions. Actual results could differ from those estimates. Key accounting policies, including but not limited to those relating to revenue recognition, operating leases, impairment of long-lived assets and goodwill, derivative financial instruments and accounting for income taxes, are impacted significantly by judgments, assumptions and estimates used in the preparation of the consolidated financial statements.
Description Of Business	Description of Business The company operates within four business segments: (1) ethanol production, which includes the production of ethanol, including industrial-grade alcohol, distillers grains and corn oil, (2) agribusiness and energy services, which includes grain handling and storage, commodity marketing and merchant trading for company-produced and third-party ethanol, distillers grains, corn oil, natural gas and other commodities, (3) food and ingredients, which includes food-grade corn oil and (4) partnership, which includes fuel storage and transportation services.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents includes bank deposits as well as short-term, highly liquid investments with original maturities of three months or less.
Restricted Cash	Restricted Cash The company has restricted cash, which can only be used for funding letters of credit or for payment towards a revolving credit agreement. Restricted cash also includes cash margins and securities pledged to commodity exchange clearinghouses and at times, funds in escrow related to acquisition and disposition activities. To the degree these segregated balances are cash and cash equivalents, they are considered restricted cash on the consolidated balance sheets.
Revenue Recognition	Revenue Recognition The company recognizes revenue when obligations under the terms of a contract with a customer are satisfied. Generally this occurs with the transfer of control of products or services. Revenue is measured as the amount of consideration expected to be received in exchange for transferring goods or providing services. Sales, value add, and other taxes the company collects concurrent with revenue-producing activities are excluded from revenue. Sales of ethanol, distillers grains, corn oil, natural gas and other commodities by the company’s marketing business are recognized when obligations under the terms of a contract with a customer are satisfied. Generally, this occurs with the transfer of control of products or services. Revenues related to marketing for third parties are presented on a gross basis as the company controls the product prior to the sale to the end customer, takes title of the product and has inventory risk. Unearned revenue is recorded for goods in transit when the company has received payment but control has not yet been transferred to the customer. Revenues for receiving, storing, transferring and transporting ethanol and other fuels are recognized when the product is delivered to the customer. The company routinely enters into physical-delivery energy commodity purchase and sale agreements. At times, the company settles these transactions by transferring its obligations to other counterparties rather than delivering the physical commodity. Energy trading transactions are reported net as a component of revenue. Revenues include net gains or losses from derivatives related to products sold while cost of goods sold includes net gains or losses from derivatives related to commodities purchased. Revenues also include realized gains and losses on related derivative financial instruments and reclassifications of realized gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Sales of products, including agricultural commodities, are recognized when control of the product is transferred to the customer, which depends on the agreed upon shipment or delivery terms. Revenues related to grain merchandising are presented gross and include shipping and handling, which is also a component of cost of goods sold. Revenues from grain storage are recognized over time as the services are rendered. A substantial portion of the partnership revenues are derived from fixed-fee commercial agreements for storage, terminal or transportation services. The partnership recognizes revenue upon transfer of control of product from its storage tanks and fuel terminals, when railcar volumetric capacity is provided, and as truck transportation services are performed. To the extent shortfalls associated with minimum volume commitments in the previous four quarters continue to exist, volumes in excess of the minimum volume commitment are applied to those shortfalls. Remaining excess volumes generating operating lease revenue are recognized as incurred.
Shipping and Handling Costs	Shipping and Handling Costs The company accounts for shipping and handling activities related to contracts with customers as costs to fulfill its promise to transfer the associated products. Accordingly, the company records customer payments associated with shipping and handling costs as a component of revenue, and classifies such costs as a component of cost of goods sold.
Cost Of Goods Sold	Cost of Goods Sold Cost of goods sold includes direct labor, materials, shipping and plant overhead costs. Direct labor includes all compensation and related benefits of non-management personnel involved in ethanol production. Grain purchasing and receiving costs, excluding labor costs for grain buyers and scale operators, are also included in cost of goods sold. Materials include the cost of corn feedstock, denaturant, and process chemicals. Corn feedstock costs include gains and losses on related derivative financial instruments not designated as cash flow hedges, inbound freight charges, inspection costs and transfer costs, as well as reclassifications of gains and losses on cash flow hedges from accumulated other comprehensive income or loss. Plant overhead consists primarily of plant utilities, repairs and maintenance and outbound freight charges. Shipping costs incurred by the company, including railcar costs, are also reflected in cost of goods sold. The company uses exchange-traded futures and options contracts and forward purchase and sale contracts to attempt to minimize the effect of price changes on ethanol, grain and natural gas. Exchange-traded futures and options contracts are valued at quoted market prices and settled predominantly in cash. The company is exposed to loss when counterparties default on forward purchase and sale contracts. Grain inventories held for sale and forward purchase and sale contracts are valued at market prices when available or other market quotes adjusted for differences, primarily in transportation, between the exchange-traded market and local market where the terms of the contract is based. Changes in forward purchase contracts and exchange-traded futures and options contracts are recognized as a component of cost of goods sold.
Operations and Maintenance Expenses	Operations and Maintenance Expenses In the partnership segment, transportation expenses represent the primary component of operations and maintenance expenses. Transportation expenses include railcar leases, freight and shipping of the company’s ethanol and co-products, as well as costs incurred storing ethanol at destination terminals.
Derivative Financial Instruments	Derivative Financial Instruments The company uses various derivative financial instruments, including exchange-traded futures and exchange-traded and over-the-counter options contracts, to attempt to minimize risk and the effect of commodity price changes including but not limited to, corn, ethanol, natural gas and crude oil. The company monitors and manages this exposure as part of its overall risk management policy to reduce the adverse effect market volatility may have on its operating results. The company may hedge these commodities as one way to mitigate risk; however, there may be situations when these hedging activities themselves result in losses. By using derivatives to hedge exposures to changes in commodity prices, the company is exposed to credit and market risk. The company’s exposure to credit risk includes the counterparty’s failure to fulfill its performance obligations under the terms of the derivative contract. The company minimizes its credit risk by entering into transactions with high quality counterparties, limiting the amount of financial exposure it has with each counterparty and monitoring their financial condition. Market risk is the risk that the value of the financial instrument might be adversely affected by a change in commodity prices or interest rates. The company manages market risk by incorporating parameters to monitor exposure within its risk management strategy, which limits the types of derivative instruments and strategies the company can use and the degree of market risk it can take using derivative instruments. The company evaluates its physical delivery contracts to determine if they qualify for normal purchase or sale exemptions which are expected to be used or sold over a reasonable period in the normal course of business. Contracts that do not meet the normal purchase or sale criteria are recorded at fair value. Changes in fair value are recorded in operating income unless the contracts qualify for, and the company elects, cash flow hedge accounting treatment. Certain qualifying derivatives related to ethanol production and agribusiness and energy services are designated as cash flow hedges. The company evaluates the derivative instrument to ascertain its effectiveness prior to entering into cash flow hedges. Unrealized gains and losses are reflected in accumulated other comprehensive income or loss until the gain or loss from the underlying hedged transaction is realized and the physical transaction is completed. When it becomes probable a forecasted transaction will not occur, the cash flow hedge treatment is discontinued, which affects earnings. These derivative financial instruments are recognized in current assets or current liabilities at fair value. At times, the company hedges its exposure to changes in inventory values and designates qualifying derivatives as fair value hedges. The carrying amount of the hedged inventory is adjusted in the current period for changes in fair value. Ineffectiveness of the hedges is recognized in the current period to the extent the change in fair value of the inventory is not offset by the change in fair value of the derivative.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In December 2019, the FASB issued amended guidance in ASC 740, Income Taxes - Simplifying the Accounting for Income Taxes, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 74 0. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted. The company is evaluating the impact of this standard on its consolidated financial statements. In March 2020, the FASB issued amended guidance in ASC 848, Reference Rate Reform - Facilitation of the Effects of Reference Rate Reform on Financial Reporting, which provides optional expedients and exceptions to U.S. GAAP guidance on contract modifications and hedge accounting to ease the financial reporting burden related to the expected market transition from the LIBOR and other interbank offered rates to alternative reference rates. The expedients and exceptions provided by the amended guidance do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The guidance is effective upon issuance and to be applied prospectively from any date beginning March 12, 2020 through December 31, 2022. The amended guidance is not expected to have a material impact on the company’s consolidated financial statements.
