Summary Of Significant Accounting Policies [Abstract] |
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 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 and vinegar production until the sale of Fleischmann’s Vinegar during the fourth quarter of 2018. 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 basis 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. Estimated fair values carried at market are based on exchange-quoted prices, adjusted as appropriate for regional location basis values which represent differences in local markets including transportation as well as quality or grade differences. Basis values are generally determined using inputs from broker quotations or other market transactions. However a portion of the value may be derived using unobservable inputs. 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.
Concentrations of Credit Risk | Concentrations of Credit Risk The company is exposed to credit risk resulting from the possibility that another party may fail to perform according to the terms of the company’s contract. The company sells ethanol, corn oil and distillers grains and markets products for third parties, which can result in concentrations of credit risk from a variety of customers, including major integrated oil companies, large independent refiners, petroleum wholesalers and other marketers. The company also sells grain to large commercial buyers, including other ethanol plants. Although payments are typically received within fifteen days of the sale, the company continually monitors its exposure. The company is also exposed to credit risk on prepayments of undelivered inventories with a few major suppliers of petroleum products and agricultural inputs. The company has master netting arrangements with various counterparties. On the consolidated balance sheets, the associated net amount for each counterparty is reflected as either an accounts receivable or accounts payable. If the amount for each counterparty were reflected on a gross basis, the company’s accounts receivable and accounts payable would increase by $1.1 million and $1.2 million at December 31, 2020 and 2019, respectively.
Inventories | ‎ Inventories Corn held for ethanol production, ethanol, corn oil and distillers grains inventories are recorded at the lower of average cost or net realizable value. Other grain inventories include readily marketable grain, forward contracts to buy and sell grain, and exchange traded futures and option contracts, which are all stated at market value. All grain inventories held for sale are marked to market. Changes are reflected in cost of goods sold. The forward contracts require performance in future periods. Contracts to purchase grain generally relate to current or future crop years for delivery periods quoted by regulated commodity exchanges. Contracts for the sale of grain to processors or other consumers generally do not extend beyond one year. The terms of the purchase and sale agreements for grain are consistent with industry standards. Raw materials and finished goods inventories are valued at the lower of average cost or net realizable value.
Property and Equipment | Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is generally calculated using the straight-line method over the following estimated useful life of the assets:
| Years
Plant, buildings and improvements | 10-40
Production equipment | 15-40
Other machinery and equipment | 5-7
Land improvements | 20
Railroad track and equipment | 20
Computer hardware and software | 3-5
Office furniture and equipment | 5-7
Property and equipment is capitalized at cost. Land improvements and other property improvements are capitalized and depreciated. Costs of repairs and maintenance are charged to expense when incurred. The company periodically evaluates whether events and circumstances have occurred that warrant a revision of the estimated useful life of its fixed assets.
Intangible Assets | Intangible Assets Our intangible assets consist primarily of customer relationships, intellectual property, research and development technology and licenses. These intangible assets were capitalized at fair market value and are being amortized over their estimated useful lives.
Impairment of Long-Lived Assets | Impairment of Long-Lived Assets The company reviews its long-lived assets, currently consisting of property and equipment, operating lease right-of-use assets, intangible assets and equity method investments, for impairment whenever events or changes in circumstances indicate the carrying amount of the asset may not be recoverable. Recoverability of assets to be held and used is measured by comparison of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds the fair value of the asset. Significant management judgment is required to determine the fair value of our long-lived assets and measure impairment, which includes projected cash flows. Fair value is determined by using various valuation techniques, including discounted cash flow models, sales of comparable properties and third-party independent appraisals. Changes in estimated fair value could result in an impairment of the asset. There were no material impairment charges recorded for the periods reported.
Goodwill | Goodwill Goodwill is an asset representing the future economic benefits arising from other assets acquired in a business combination that are not individually identified and separately recognized. The determination of goodwill takes into consideration the fair value of net tangible and intangible assets. The company’s goodwill is related to certain acquisitions within our ethanol production and partnership segments. On January 1, 2018, the company early adopted the amended guidance in ASC 350, Intangibles – Goodwill and Other: Simplifying the Test for Goodwill Impairment, which simplifies the measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Under the amended guidance, an entity may first assess qualitative factors to determine whether it is necessary to perform a quantitative goodwill impairment test. If determined to be necessary, the quantitative impairment test shall be used to identify goodwill impairment and measure the amount of a goodwill impairment loss to be recognized (if any). The company is required to perform impairment tests related to goodwill annually, which it performs as of October 1, or sooner if an indicator of impairment occurs. Circumstances that may indicate impairment include a decline in the company’s future projected cash flows, a decision to suspend plant operations for an extended period of time, sustained decline in the company’s market capitalization or market prices for similar assets or businesses, or a significant adverse change in legal or regulatory matters or business climate. Significant management judgment is required to determine the fair value of goodwill and measure impairment, which include, but are not limited to, market capitalization, prospective financial information, growth rates, discount rates, inflationary factors, and cost of capital. Fair value is determined by using various valuation techniques, including discounted cash flow models, sales of comparable properties and third-party independent appraisals. Changes in estimated fair value could result in a write-down of the asset. 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 and as such 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. The company also identified triggering events due to decreases in the partnership’s stock price and as a result, its market capitalization, and performed interim quantitative goodwill assessments as of March 31, 2020 and June 30, 2020. The company performed its annual goodwill assessment as of October 1, 2020, using a qualitative assessment. Each of the goodwill assessments resulted in no goodwill impairment. For additional information, please refer to Note 10 – Goodwill and Intangible Assets. Leases On January 1, 2019, the company adopted the amended guidance in ASC 842, Leases, and all related amendments and applied it to all leases using the optional transition method which requires the amended guidance to be applied at the date of adoption. The standard does not require the guidance to be applied to the earliest comparative period presented in the financial statements. As such, comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The company leases certain facilities, parcels of land, and equipment. These leases are accounted for as operating leases, with lease expense recognized on a straight-line basis over the lease term. The term of the lease may include options to extend or terminate the lease when it is reasonably certain that such options will be exercised. For leases with initial terms greater than 12 months, the company records operating lease right-of-use assets and corresponding operating lease liabilities. Leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet. The company did not incur any material short-term lease expense for the years ended December 31, 2020 or 2019. Operating lease right-of-use assets represent the right to control an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. These assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. As the company’s leases do not provide an implicit rate, the incremental borrowing rate is used based on information available at commencement date to determine the present value of future payments. The company elected to utilize a portfolio approach for lease classification, which allows for an entity to group together leases with similar characteristics provided that its application does not create a material difference when compared to accounting for the leases at a contract level. For railcar leases, the company elected to combine the railcars within each rider and account for each rider as an individual lease. From a lessee perspective, the company combines both the lease and non-lease components and accounts for them as one lease. Certain of the company’s railcar agreements provide for maintenance costs to be the responsibility of the company as incurred or charged by the lessor. This maintenance cost is a non-lease component that the company combines with the monthly rental payment and accounts for the total cost as operating lease expense. In addition, the company has a land lease that contains a non-lease component for the handling and unloading services the landlord provides. The company combines the cost of services with the land lease cost and accounts for the total as operating lease expense. The partnership segment records the majority of it operating lease revenue from its storage and throughput services, rail transportation services and certain terminal services agreements with Green Plains Trade. In addition, the partnership may sublease certain of its railcars to third parties on a short-term basis. These subleases are classified as operating leases, with the associated sublease revenue recognized on a straight-line basis over the lease term. Please refer to Note 18 – Commitments and Contingencies to the consolidated financial statements for further details on operating lease expense and revenue. Investments in Equity Method Investees The company accounts for investments in which the company exercises significant influence using the equity method so long as the company (i) does not control the investee and (ii) is not the primary beneficiary of the entity. The company recognizes these investments as a separate line item in the consolidated balance sheets and its proportionate share of earnings on a separate line item in the consolidated statements of operations. The company’s share of equity method investees other comprehensive income arising during the period is included in accumulated other comprehensive loss in the consolidated balance sheet. The company recognizes losses in the value of equity method investments when there is evidence of an other-than-temporary decrease in value. Evidence of a loss might include, but would not necessarily be limited to, the inability to recover the carrying amount of the investment or the inability of the equity method investee to sustain an earnings capacity that justifies the carrying amount of the investment. The current fair value of an investment that is less than its carrying amount may indicate a loss in value of the investment. The company evaluates equity method investments for impairment if there is evidence an investment may be impaired. We use the nature of distribution approach to classify distributions from equity method investments on the statements of cash flows.
Leases | Leases On January 1, 2019, the company adopted the amended guidance in ASC 842, Leases, and all related amendments and applied it to all leases using the optional transition method which requires the amended guidance to be applied at the date of adoption.

Investments in Equity Method Investees | Investments in Equity Method Investees The company accounts for investments in which the company exercises significant influence using the equity method so long as the company (i) does not control the investee and (ii) is not the primary beneficiary of the entity. The company recognizes these investments as a separate line item in the consolidated balance sheets and its proportionate share of earnings on a separate line item in the consolidated statements of operations. The company’s share of equity method investees other comprehensive income arising during the period is included in accumulated other comprehensive loss in the consolidated balance sheet. The company recognizes losses in the value of equity method investments when there is evidence of an other-than-temporary decrease in value. Evidence of a loss might include, but would not necessarily be limited to, the inability to recover the carrying amount of the investment or the inability of the equity method investee to sustain an earnings capacity that justifies the carrying amount of the investment. The current fair value of an investment that is less than its carrying amount may indicate a loss in value of the investment. The company evaluates equity method investments for impairment if there is evidence an investment may be impaired. We use the nature of distribution approach to classify distributions from equity method investments on the statements of cash flows.
Discontinued Operations | Discontinued Operations In determining whether a disposal group should be presented as discontinued operations, the company makes a determination of whether such a group being disposed of comprises a component of the entity, or a group of components of the entity, that represents a strategic shift that has, or will have, a major effect on the company's operations and financial results. If these determinations are made affirmatively, the results of operations of the group being disposed of are aggregated for separate presentation apart from the continuing operations of the company for all periods presented in the consolidated financial statements. General corporate overhead is not allocated to discontinued operations. Net income from discontinued operations, net of income taxes, relates to the operations of GPCC, which was previously a wholly owned subsidiary of Green Plains until the formation of the GPCC joint venture and partial sale during the third quarter of 2019. The assets and liabilities of GPCC have been reclassified as assets and liabilities of discontinued operations in the prior year. The company entered into a shared service agreement whereby they continued to provide certain administrative services to GPCC and received $400 thousand on a quarterly basis through December 31, 2020, at which time administrative services began to unwind as a result of the disposition of the GPCC joint venture on October 1, 2020. Associated services are not expected to be material in the future.
Financing Costs | Financing Costs Fees and costs related to securing debt are recorded as financing costs. Debt issuance costs are stated at cost and are amortized using the effective interest method for term loans and the straight-line basis over the life of the agreements for revolving credit arrangements and convertible notes. During periods of construction, interest is capitalized in construction-in-progress.
Selling, General and Administrative Expenses | Selling, General and Administrative Expenses Selling, general and administrative expenses consist of various expenses including employee salaries, incentives and benefits; office expenses; director compensation; professional fees for accounting, legal, consulting, and investor relations activities.
Stock-Based Compensation | Stock-Based Compensation The company recognizes compensation cost using a fair value based method whereby compensation cost is measured at the grant date based on the value of the award and is recognized over the service period, which is usually the vesting period. The company uses the Black-Scholes pricing model to calculate the fair value of options and warrants issued to both employees and non-employees. The company used the Monte Carlo valuation model to estimate the fair value of performance shares issued to employees. Stock issued for compensation is valued using the market price of the stock on the date of the related agreement.
Income Taxes | Income Taxes
Recent Accounting Pronouncements | Recent Accounting Pronouncements Effective January 1, 2020, the company adopted the amended guidance in ASC 326, Financial Instruments - Credit Losses, which replaces the current incurred loss impairment method with a method that reflects expected credit losses on financial instruments. The new standard is effective for fiscal years and interim periods within those years, beginning after December 15, 2019, and allows for early adoption. The adoption of the new guidance did not have a material impact on the company’s consolidated financial statements. 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. In August 2020, the FASB issued amended guidance in ASC 470-20, Debt - Debt with Conversion and Other Options and ASC 815-40, Derivatives and Hedging - Contracts in Entity’s Own Equity - Accounting for Convertible Instruments and Contracts in an Equity’s Own Equity. The amended guidance simplifies the accounting for convertible debt instruments by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. The amended guidance also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. The amended guidance is effective for fiscal periods beginning after December 15, 2021, including interim periods within those fiscal periods. Early adoption is permitted, but no earlier than fiscal periods beginning after December 15, 2020. The amended guidance permits the use of either the modified retrospective or fully retrospective method of transition. The company intends on adopting the amended guidance on January 1, 2022 using the modified retrospective method of transition. The company is evaluating the impact of this standard on its consolidated financial statements and anticipates it will result in an increase to long-term debt and a decrease in additional paid-in-capital as well as a reduction of non-cash interest expense related to the company’s convertible notes.
