General

The following discussion and analysis includes information management believes is relevant to understand and assess our consolidated financial condition and results of operations. This section should be read in conjunction with our consolidated financial statements, accompanying notes and the risk factors contained in this report.

Overview

Green Plains is an Iowa corporation, founded in June 2004 as a producer of low carbon fuels. We have grown through acquisitions of ethanol production facilities and adjacent commodity processing businesses to be one of the leading corn processors in the world. We are in the process of transforming ourselves to be focused on the production of high-protein feed

ingredients and export growth opportunities. Additionally, we have taken advantage of strategic opportunities to divest certain assets in recent years. We are focused on generating stable operating margins through our business segments and risk management strategy. We own and operate assets throughout the ethanol value chain: upstream, with grain handling and storage; through our ethanol production facilities; and downstream, with marketing and distribution services to mitigate commodity price volatility, which differentiates us from companies focused only on ethanol production. Our other businesses leverage our supply chain, production platform and expertise.

Our profitability is highly dependent on commodity prices, particularly for ethanol, distillers grains, corn oil, corn, and natural gas. Since market price fluctuations of these commodities are not always correlated, our operations may be unprofitable at times. We use a variety of risk management tools and hedging strategies to monitor price risk exposure at our ethanol plants and lock in favorable margins or reduce production when margins are compressed. Our adjacent businesses integrate complementary but more predictable revenue streams that diversify our operations and profitability.

More information about our business, properties and strategy can be found under Item 1 - Business and a description of our risk factors can be found under Item 1A - Risk Factors.

Industry Factors Affecting our Results of Operations

U.S. Ethanol Supply and Demand

According to the EIA, domestic ethanol production averaged 1.03 million barrels per day in 2019, which was 1.7% lower than the 1.05 million barrels per day in 2018. Refiner and blender input volume increased 1% to 921 thousand barrels per day for 2019, compared with 914 thousand barrels per day in 2018. Gasoline demand increased 27 thousand barrels per day, or 0.3% in 2019. U.S. domestic ethanol ending stocks decreased by approximately 2.1 million barrels, or 9%, year over year to 21.0 million barrels. At the end of May 2019, the EPA finalized regulatory changes to apply the 1 pound per square inch Reid Vapor Pressure (RVP) waiver that currently applies to E10 during the summer months so that it applies to E15 as well. This removes a significant barrier to wider sales of E15 in the summer months, thus expanding the market for ethanol in transportation fuel. As of December 31, 2019, there were approximately 2,080 retail stations selling E15 in 30 states, up from 1,700 at the beginning of the year, according to Growth Energy.

Global Ethanol Supply and Demand

According to the USDA Foreign Agriculture Service, domestic ethanol exports through November 30, 2019 were approximately 1.32 bg, down 15% from 1.56 bg for the same period of 2018. Brazil remained the largest export destination for U.S. ethanol, which accounted for 23% of domestic ethanol export volume despite the 20% tariff on U.S. ethanol imports in excess of 150 million liters, or 39.6 million gallons per quarter, imposed in September 2017 by Brazil's Chamber of Foreign Trade, or CAMEX. In a resolution published August 31, 2019, Brazil raised the annual import quota to 750 million liters, or 198 million gallons per year from the expiring 600 million-liter limit. The final resolution awaits approval of the Brazilian government. In addition, Canada, India, South Korea, and the Philippines accounted for 23%, 12%, 7%, and 5%, respectively, of U.S. ethanol exports.

On April 1, 2018, China announced it would add an additional 15% tariff to the existing 30% tariff it had earlier imposed on ethanol imports from the United States and Brazil. China later raised the tariff further to 70% as the trade war escalated. In January 2020, China and the United States agreed to certain trade agreements, the impact of which on ethanol are yet to be determined.

The cost to produce the equivalent amount of starch found in sugar from $3.50-per-bushel corn is 7 cents per pound. The average price of sugar was approximately 12 cents per pound during 2019. We currently estimate that net ethanol exports will reach approximately 1.5 billion gallons in 2020, excluding any potential exports to China, based on historical demand from a variety of countries and certain countries who seek to improve their air quality and eliminate MTBE from their own fuel supplies.

Year-to-date U.S. distillers grains exports through November 30, 2019, were 10.0 million metric tons, or 9.7% lower than the same period last year, according to the USDA Foreign Agriculture Service. Mexico, South Korea, Vietnam, Indonesia, Canada, and Turkey, accounted for approximately 61% of total U.S. distillers export volumes.

While African Swine Fever (ASF) may have a positive impact on animal protein demand from the U.S., it may have a negative impact on distillers grains exports and domestic usage. ASF may depress soybean meal demand in China which could make the animal feed more price competitive to distillers grains and allow for substitution of high-protein soybean meal worldwide.

Legislation and Regulation

We are sensitive to government programs and policies that affect the supply and demand for ethanol and other fuels, which in turn may impact the volume of ethanol and other fuels we handle. Various bills have been discussed in the House and Senate which would eliminate the RFS II entirely, eliminate the corn based ethanol portion of the mandate, or make it more difficult to sell fuel blends with higher levels of ethanol. We believe it is unlikely that any of these bills will become law in the current Congress. In addition, the manner in which the EPA administers the RFS II can have a significant impact on the actual amount of ethanol blended into the domestic fuel supply.

Federal mandates supporting the use of renewable fuels are a significant driver of ethanol demand in the U.S. Ethanol policies are influenced by concerns for the environment, diversifying our fuel supply, and reducing the country's dependence on foreign oil. Consumer acceptance of flex-fuel vehicles and higher ethanol blends of ethanol in non-flex-fuel vehicles may be necessary before ethanol can achieve further growth in U.S. market share. Congress first enacted CAFE in 1975 to reduce energy consumption by increasing the fuel economy of cars and light trucks.

Flexible-fuel vehicles (FFVs), which are designed to run on a mixture of fuels, including higher blends of ethanol such as E85, receive preferential treatment in the form of CAFE credits. There are approximately 21 million FFVs on the road in the U.S. today, 16 million of which are light duty trucks. FFV credits have been decreasing since 2014 and will be completely phased out in 2020. Absent CAFE preferences, auto manufacturers may not be willing to build flexible-fuel vehicles, which has the potential to slow the growth of E85 markets.

Another important factor is a waiver in the Clean Air Act, known as the One-Pound Waiver, which allows E10 to be sold year-round, even though it exceeds the Reid Vapor Pressure limitation of nine pounds per square inch. At the end of May 2019, the EPA finalized a rule which extended the One-Pound Waiver to E15. This allows E15 to be sold year round to all vehicles model year 2001 and newer. This rule is being challenged in an action filed in Federal District Court for the DC Circuit. However, the One-Pound Waiver is in effect, and for the first time ever, E15 was legally sold to all vehicles model year 2001 and newer during the summer driving season of June 1 to September 15, 2019.

The RFS II has been a driving factor in the growth of ethanol usage in the United States. When the RFS II was established in 2010, the required volume of "conventional" corn-based ethanol to be blended with gasoline was to increase each year until it reached 15.0 billion gallons in 2015, which left the EPA to address existing limitations in both supply (ethanol production) and demand (usage of ethanol blends in older vehicles). On December 19, 2019, the EPA announced the final 2020 RVO for conventional ethanol, which met the 15.0-billion-gallon congressional target.

The EPA has the authority to waive the mandates, in whole or in part, if there is inadequate domestic renewable fuel supply or the requirement severely harms the economy or environment. According to the RFS II, if mandatory renewable fuel volumes are reduced by at least 20% for two consecutive years, the EPA is required to modify, or reset, statutory volumes through 2022 - the year through which the statutorily prescribed volumes run. While conventional ethanol maintained 15 billion gallons, 2019 was the second consecutive year that the total proposed RVO was more than 20% below statutory volumes levels. Thus, the EPA was expected to initiate a reset rulemaking, and modify statutory volumes through 2022, and do so based on the same factors they are to use in setting the RVOs post-2022. These factors include environmental impact, domestic energy security, expected production, infrastructure impact, consumer costs, job creation, price of agricultural commodities, food prices, and rural economic development. However, on December 19, 2019, the EPA announced it would not be moving forward with a reset rulemaking in 2020.

The EPA assigns individual refiners, blenders, and importers the volume of renewable fuels they are obligated to use based on their percentage of total domestic transportation fuel sales. Obligated parties use RINs to show compliance with the RFS II mandated volumes. Ethanol producers assign RINs to renewable fuels and the RINs are detached when the renewable fuel is blended with transportation fuel domestically. Market participants can trade the detached RINs in the open market. The market price of detached RINs affects the price of ethanol in certain markets and influences the purchasing decisions by obligated parties.

Under the RFS II, a small refinery is defined as one that processes fewer than 75,000 barrels of petroleum per day. Small refineries can petition the EPA for a SRE which, if approved, waives their portion of the annual RVO requirements. The EPA, through consultation with the Department of Energy and the Department of Agriculture, can grant them a full or partial waiver, or deny it outright within 90 days of submittal. The EPA granted significantly more of these waivers for 2016, 2017 and 2018 than they had in the past, totaling 790 million gallons of waived requirements for the 2016 compliance year, 1.82 billion gallons for 2017 and 1.43 billion gallons for 2018. In doing so, the EPA effectively reduced the RFS II mandated volumes for those compliance years by those amounts respectively, and as a result, RIN values have declined significantly.

Biofuels groups have filed a lawsuit in the Court of Appeals for the D.C. Circuit, challenging the 2019 RVO rule over the EPA's failure to address small refinery exemptions in the rulemaking. This was the first RFS II rulemaking since the expanded use of the exemptions came to light; however, the EPA had declined to cap the number of waivers it grants, and until late 2019, had declined to alter how it accounts for the retroactive waivers in its annual volume calculations. The EPA has a statutory mandate to ensure the volume requirements are met, which are achieved by setting the percentage standards for obligated parties. The EPA's recent approach accomplished the opposite. Even if all the obligated parties complied with their respective percentage obligations for 2019, the nation's overall supply of renewable fuel would not meet the total volume requirements set by the EPA. This undermines Congressional intent to increase the consumption of renewable fuels in the domestic transportation fuel supply. Biofuels groups have argued the EPA must therefore adjust its percentage standard calculations to make up for past retroactive waivers and adjust the standards to account for any waivers it reasonably expects to grant in the future.

In a supplemental rulemaking to the 2020 RVO rule, the EPA changed their approach, and for the first time are accounting for the gallons they anticipate they will be waiving from the blending requirements due to small refinery exemptions. To accomplish this, they are adding in the trailing three year average of gallons the Department of Energy recommended be waived, in effect raising the blending volumes across the board in anticipation of waiving the obligations in whole or in part for certain refineries that qualify for the exemptions. Though the EPA has often disregarded the recommendations of the Department of Energy in years past, they stated in the rule their intent to adhere to these recommendations going forward, including granting partial waivers rather than an all or nothing approach. The EPA will be adjudicating the 2020 compliance year small refinery exemption applications in early 2021, but have indicated they will adhere to Department of Energy recommendations for the 2019 compliance year applications as well, which should be adjudicated in early 2020. There were 21 applications pending as of this filing.

On January 24, 2020, the U.S. Court of Appeals for the 10th Circuit ruled on RFA et. al. vs. EPA in favor of biofuels interests, overturning EPA's grant of refinery exemptions to three refineries on two separate grounds. The Court agreed that, under the Clean Air Act, refineries are eligible for SREs for a given RVO year only if such exemptions are extensions of exemptions granted in previous RVO years. In this case, the three refineries at issue did not qualify for SREs in the year prior to the year that EPA granted them. They were thus ineligible for additional SRE relief because there were no immediately prior SREs to extend. In addition, the Court agreed that the disproportionate economic hardship prong of SRE eligibility should be determined solely by reference to whether compliance with the RFS II creates such hardship, not whether compliance plus other issues create disproportionate economic hardship. The Court thus vacated EPA's grant of SREs for certain years and remanded the grants back to EPA. It is expected the decision will be appealed to the U.S. Supreme Court. If the decision against the EPA is upheld by the Supreme Court, it is uncertain how the EPA will propose to remedy the situation.

The White House directed the USDA and EPA to move forward with rulemaking to expand access to higher blends of biofuels. This includes funding for infrastructure, labeling changes and allowing E15 to be sold through E10 infrastructure.

In 2017, the D.C. Circuit ruled in favor of biofuel groups against the EPA related to its decision to lower the 2016 volume requirements by 500 million gallons. As a result, the Court remanded to the EPA to make up for the 500 million gallons. Despite this, in the proposed 2020 RVO rulemaking released in July 2019, the EPA stated it does not intend to make up the 500 million gallons as the court directed, citing potential burden on obligated parties. The EPA has indicated that it plans to address this court ordered remand in early 2020.

Government actions abroad can significantly impact the demand for U.S. ethanol. In September 2017, China's National Development and Reform Commission, the National Energy Board and 15 other state departments issued a joint plan to expand the use and production of biofuels containing up to 10% ethanol by 2020. China, the number three importer of U.S. ethanol in 2016, imported negligible volumes during 2018 and 2019 due to a 30% tariff on U.S. ethanol, which increased to 70% in early 2018. There is no assurance that China's joint plan to expand blending to 10% will be carried to fruition, nor that it will lead to increased imports of U.S. ethanol in the near term. Ethanol is included as an agricultural commodity under the "Phase I" agreement with China, wherein they are to purchase upwards of $40 billion in agricultural commodities from the U.S. in both 2020 and 2021.

In Brazil, the Secretary of Foreign Trade issued an official written resolution, imposing a 20% tariff on U.S. ethanol imports in excess of 150 million liters, or 39.6 million gallons per quarter in September 2017. The initial ruling was valid for two years; however, it was extended at the end of August 2019 for an additional year. On an annual basis, Brazil will now allow into the country 750 million duty free liters distributed on a quarterly basis as follows: September to November 100 million liters, December to February 100 million liters, March to May 275 million liters and June to August 275 million liters.

Our exports also face tariffs, rate quotas, countervailing duties, and other hurdles in the European Union, India, Peru, and elsewhere, which limits the ability to compete in some markets.

In June 2017, the Energy Regulatory Commission of Mexico (CRE) approved the use of 10% ethanol blends, which was challenged by multiple lawsuits, of which several were dismissed. The remaining four cases follow one of two tracks: 1) to determine the constitutionality of the CRE regulation, or 2) to determine the benefits, or lack thereof, of introducing E10 to Mexico. An injunction was granted in October 2017, preventing the blending and selling of E10, but was overturned by a higher court in June 2018 making it legal to blend and sell E10 by PEMEX throughout Mexico except for its three largest metropolitan areas. On January 15, 2020, the Mexican Supreme Court ruled that the expedited process for the CRE regulation was unconstitutional, and that after a 180 day period the maximum ethanol blend allowed in the country would revert to 5.8%. There is an effort underway to go through the full regulatory process to allow for 10% blends countrywide, including in the three major metropolitan areas. U.S. ethanol exports to Mexico totaled 29.4 mmg in 2018 and 29.8 mmg in 2019.

On January 29, 2020, the President signed into law the updated North American Free Trade Agreement, known as the United States Mexico Canada Agreement or USMCA. The pact maintains the duty free access of U.S. agricultural commodities, including ethanol, into Canada and Mexico. As of the date of this filing, Mexico has ratified the pact and the Canadian Parliament is widely expected to do the same.

The Tax Cuts and Jobs Act (the "Act") was signed into law on December 22, 2017, effective on January 1, 2018. Among other provisions, the new law reduced the federal statutory corporate income tax rate from 35% to 21%. The tax impacts of the Act are included in our consolidated financial statements.

Environmental and Other Regulation

Our operations are subject to environmental regulations, including those that govern the handling and release of ethanol, crude oil and other liquid hydrocarbon materials. Compliance with existing and anticipated environmental laws and regulations may increase our overall cost of doing business, including capital costs to construct, maintain, operate, and upgrade equipment and facilities. Our business may also be impacted by government policies, such as tariffs, duties, subsidies, import and export restrictions and outright embargos. We employ maintenance and operations personnel at each of its facilities, which are regulated by the Occupational Safety and Health Administration.

The U.S. ethanol industry relies heavily on tank cars to deliver its product to market. On May 1, 2015, the DOT finalized the Enhanced Tank Car Standard and Operational Controls for High-Hazard and Flammable Trains, or DOT specification 117, which established a schedule to retrofit or replace older tank cars that carry crude oil and ethanol, braking standards intended to reduce the severity of accidents and new operational protocols. The deadline for compliance with DOT specification 117 is May 1, 2023. The rule may increase our lease costs for railcars over the long term. Additionally, existing railcars may be out of service for a period of time while upgrades are made, tightening supply in an industry that is highly dependent on railcars to transport product. We intend to strategically manage our leased railcar fleet to comply with the new regulations and have commenced transition of our fleet to DOT 117 compliant railcars. As of December 31, 2019, approximately 30% of our railcar fleet was DOT 117 compliant. We anticipate that an additional 20% of our railcar fleet will be DOT 117 compliant by the end of 2020, and that our entire fleet will be fully compliant by 2023.

In September 2015, the FDA issued rules for Current Good Manufacturing Practice, Hazard Analysis and Risk-Based Preventative Controls for food for animals in response to FSMA. The rules require FDA-registered food facilities to address safety concerns for sourcing, manufacturing and shipping food products and food for animals through food safety programs that include conducting hazard analyses, developing risk-based preventative controls and monitoring, and addressing intentional adulteration, recalls, sanitary transportation and supplier verification. We believe we have taken sufficient measures to comply with these regulations.

On January 1, 2017, all medically important antimicrobials intended for use in animal feed that were once available over-the-counter became veterinary feed directive drugs, requiring written orders from a licensed veterinarian to purchase and use in livestock feed under the October 2015 revised Veterinary Feed Directive rule. Our cattle feeding joint venture obtained all necessary prescriptions from a licensed veterinarian to use certain veterinary feed directive drugs, as appropriate.

Variability of Commodity Prices

Our business is highly sensitive to commodity price fluctuations, particularly for corn, ethanol, corn oil, distillers grains and natural gas, which are impacted by factors that are outside of our control, including weather conditions, corn yield, changes in domestic and global ethanol supply and demand, government programs and policies and the price of crude oil,



                                       39

gasoline and substitute fuels. We use various financial instruments to manage and reduce our exposure to price variability. For more information about our commodity price risk, refer to Item 7A. - Qualitative and Quantitative Disclosures About Market Risk, Commodity Price Risk in this report.

During 2019, we continued to experience a weak ethanol margin environment. Our operating strategy, including the operating cost savings initiative, is to increase utilization rates and efficiency while reducing operating expenses to achieve improved margins. In 2019, our ethanol facilities ran at approximately 76% of our daily average capacity, largely due to the low margin environment during the year driven by higher domestic ethanol supplies resulting from weak refiner and blender input volume. We expect to run at higher average utilization rates to achieve the cost savings anticipated. Additionally, overall performance at our ethanol plants was negatively impacted by severe weather and associated flooding in areas where we transport products during the first half of 2019. The weather also drove corn prices up, negatively impacting margins.

Critical Accounting Policies and Estimates

The preparation of our consolidated financial statements requires that we use estimates that affect the reported assets, liabilities, revenue and expense and related disclosures for contingent assets and liabilities. We base our estimates on experience and assumptions we believe are proper and reasonable. While we regularly evaluate the appropriateness of these estimates, actual results could differ materially from our estimates. The following accounting policies, in particular, may be impacted by judgments, assumptions and estimates used in the preparation of our consolidated financial statements.

Revenue Recognition

We recognize 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 we collect 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 we control the product prior to the sale to the end customer, take title of the product and have inventory risk. Unearned revenue is recorded for goods in transit when we have 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.

We routinely enter into physical-delivery energy commodity purchase and sale agreements. At times, we settle these transactions by transferring 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.

Intercompany revenues are eliminated on a consolidated basis for reporting purposes.

Impairment of Long-Lived Assets and Goodwill

Our long-lived assets consist of property and equipment, operating lease right-of-use assets, intangible assets and equity method investments. We review long-lived assets for impairment whenever events or changes in circumstances indicate the



                                       40

--------------------------------------------------------------------------------

Table of Contents

carrying amount of the asset may not be recoverable. We measure recoverability by comparing the carrying amount of the asset with the estimated undiscounted future cash flows the asset is expected to generate. If the carrying amount of the asset exceeds its estimated future cash flows, we record an impairment charge for the amount in excess of the fair value. There were no material impairment charges recorded for the periods reported.

Our goodwill is related to certain acquisitions within our ethanol production and partnership segments. We review goodwill for impairment at least annually, as of October 1, or more frequently whenever events or changes in circumstances indicate that an impairment may have occurred.

Near term industry outlook and the decline in our stock price caused a decline in our market capitalization during the three months ended September 30, 2019. As such, we determined a triggering event had occurred that required an interim impairment assessment for our ethanol production reporting unit. Due to the impairment indicators noted as a result of these triggering events, we evaluated our goodwill as of September 30, 2019. Significant assumptions inherent in the valuation methodologies for goodwill are employed and include, but are not limited to, market capitalization, 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 exceeded its carrying value. As a result, we concluded that the goodwill assigned to the ethanol production reporting unit was not impaired, but could be at risk of future impairment. We continue to believe that our long-term financial goals will be achieved.

We performed our annual goodwill assessment as of October 1, 2019, using a qualitative assessment, which resulted in no goodwill impairment.

We estimate the amount and timing of projected cash flows that will be generated by an asset over an extended period of time when we review our long-lived assets and goodwill. Circumstances that may indicate impairment include: a decline in future projected cash flows, a decision to suspend plant operations for an extended period of time, a sustained decline in our market capitalization, a sustained decline in 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 our long-lived assets and goodwill and measure impairment, including projected cash flows. Fair value is determined through various valuation techniques, including discounted cash flow models utilizing assumed margins, cost of capital, inflation and other inputs, sales of comparable properties and third-party independent appraisals. Changes in estimated fair value as a result of declining ethanol margins, loss of significant customers or other factors could result in a write-down of the asset.

Leases

On January 1, 2019, we 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.

We lease certain facilities, parcels of land, and equipment. Our 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 we will exercise one of those options. For leases with initial terms greater than 12 months, we record 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 our consolidated balance sheet. Operating lease right-of-use assets represent our right to control an underlying asset for the lease term and operating lease liabilities represent our 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 our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at commencement date to determine the present value of future payments.

Our partnership segment records the majority of its operating lease revenue from its storage and throughput services and rail transportation services agreements with Green Plains Trade. The lease revenue from Green Plains Trade is eliminated upon consolidation. 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.

Derivative Financial Instruments

We use 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. We monitor and manage this exposure as part of our overall risk management policy to reduce the adverse effect market volatility may have on our operating results. We 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, we are exposed to credit and market risk. Our exposure to credit risk includes the counterparty's failure to fulfill its performance obligations under the terms of the derivative contract. We minimize our 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. We manage market risk by incorporating parameters to monitor exposure within our risk management strategy, which limits the types of derivative instruments and strategies we can use and the degree of market risk we can take using derivative instruments.

We evaluate our 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 we elect, cash flow hedge accounting treatment.

Certain qualifying derivatives related to ethanol production and agribusiness and energy services segments are designated as cash flow hedges. We evaluate 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. 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, we hedge our exposure to changes in inventory values and designate 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.

Accounting for Income Taxes

Income taxes are accounted for under the asset and liability method in accordance with GAAP. Deferred tax assets and liabilities are recognized for future tax consequences between existing assets and liabilities and their respective tax basis, and for net operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in years temporary differences are expected to be recovered or settled. The effect of a tax rate change is recognized in the period that includes the enactment date. The realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences become deductible. Management considers scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies to make this assessment. A valuation allowance is recorded by the company when it is more likely than not that some portion or all of a deferred tax asset will not be realized. In making such a determination, management considers the positive and negative evidence to support the need for, or reversal of, a valuation allowance. The weight given to the potential effects of positive and negative evidence is based on the extent it can be objectively verified.

To account for uncertainty in income taxes, we gauge the likelihood of a tax position based on the technical merits of the position, perform a subsequent measurement related to the maximum benefit and degree of likelihood, and determine the benefit to be recognized in the financial statements, if any.

Components of Revenues and Expenses

Revenues. For our ethanol production segment, our revenues are derived primarily from the sale of ethanol, distillers grains and corn oil. For our agribusiness and energy services segment, sales of ethanol, distillers grains and corn oil that we market for our ethanol plants, in which we earn a marketing fee, sales of ethanol we market for a third-party and sales of grain and other commodities purchased in the open market represent our primary sources of revenue. For our food and ingredients segment, the sale of corn oil, and vinegar prior to the sale of Fleischmann's Vinegar during the fourth quarter of 2018, are our primary sources of revenue. For our partnership segment, our revenues consist primarily of fees for receiving, storing, transferring and transporting ethanol and other fuels. Revenues include net gains or losses from derivatives related to products sold.

Cost of Goods Sold. For our ethanol production segment, cost of goods sold includes direct labor, materials and plant overhead costs. Direct labor includes compensation and related benefits of non-management personnel involved in ethanol plant operations. Plant overhead consists primarily of plant utilities and outbound freight charges. Corn is the most significant raw material cost followed by natural gas, which is used to power steam generation in the ethanol production process and dry distillers grains. Cost of goods sold also includes net gains or losses from derivatives related to commodities purchased.

For our agribusiness and energy services segment, purchases of ethanol, distillers grains, corn oil and grain are the primary component of cost of goods sold. 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, such as transportation, between the exchange-traded market and local markets where the terms of the contracts are based. Changes in the market value of grain inventories, forward purchase and sale contracts, and exchange-traded futures and options contracts are recognized as a component of cost of goods sold.

For our food and ingredients segment, food-grade ethanol was the most significant raw material cost. For our vinegar operation, which was sold during the fourth quarter of 2018, cost of goods sold included direct labor, materials and plant overhead costs. Direct labor included compensation and related benefits of non-management personnel involved in vinegar operations.

Operations and Maintenance Expense. For our partnership segment, transportation expense is the primary component of operations and maintenance expense. Transportation expense includes rail car leases, shipping and freight and costs incurred for storing ethanol at destination terminals.

Selling, General and Administrative Expense. Selling, general and administrative expenses are recognized at the operating segment and corporate level. These expenses consist of employee salaries, incentives and benefits; office expenses; director fees; and professional fees for accounting, legal, consulting and investor relations services. Personnel costs, which include employee salaries, incentives, and benefits, as well as severance and separation costs, are the largest expenditure. Selling, general and administrative expenses that cannot be allocated to an operating segment are referred to as corporate activities.

Gain on Sale of Assets, Net. We completed the sale of the three ethanol plants located in Bluffton, Indiana, Lakota, Iowa and Riga, Michigan, as well as Fleischmann's Vinegar during the fourth quarter of 2018. Proceeds from these sales, offset by related expenses, were recorded primarily at the corporate level, with only the gain on the assignment of operating leases of $2.7 million being recorded at the partnership level.

Other Income (Expense). Other income (expense) includes interest earned, interest expense and other non-operating items, including a gain of $4.8 million related to the sale of our 50% interest in JGP Energy Partners LLC.

Income (loss) from Equity Method Investees, Net of Income Taxes. Income (loss) from equity method investees, net of income taxes, represents our proportional share of earnings from our equity method investees.

Net Income from Discontinued Operations, Net of Income Taxes. Net income from discontinued operations, net of income taxes represents the operations of GPCC prior to its disposition during the third quarter of 2019. GPCC was previously a wholly owned subsidiary of Green Plains until the formation of the GPCC joint venture and disposition September 1, 2019.

Results of Operations

Comparability

The following summarizes various events that affect the comparability of our operating results for the past three years:



? March 2017      Hereford, Texas cattle feeding operation was acquired.
? May 2017        Leoti, Kansas and Eckley, Colorado cattle feeding operations
                  were acquired.
? August 2018     Sublette, Kansas and Tulia, Texas cattle feeding operations
                  were acquired.

? November 2018 Bluffton, Indiana, Lakota, Iowa and Riga, Michigan ethanol


                  plants were sold and certain storage assets of these plants
                  were acquired from the partnership prior to being sold.

? November 2018 Hopewell, Virginia ethanol plant was permanently closed. ? November 2018 Fleischmann's Vinegar was sold. ? September 2019 An aggregate 50% membership interest of GPCC was sold,


                  resulting in the deconsolidation of GPCC and the equity method
                  of accounting treatment of our continued investment.
                  Operational results of GPCC prior to its disposition, for all
                  periods presented have been reclassified as discontinued
                  operations in our consolidated financial statements. The
                  assets and liabilities of GPCC have been reclassified as
                  assets and liabilities of discontinued operations in all prior
                  periods.

? December 2019 Our 50% membership interest in JGP Energy Partners was sold.

The year ended December 31, 2017, includes approximately nine months of operations at our Hereford cattle feeding business and approximately six months of operations at our Leoti and Eckley cattle feeding operations. The year ended December 31, 2018, includes approximately five months of operations at our Sublette and Tulia cattle feeding businesses, eleven months of operations at our Bluffton, Lakota, Hopewell and Riga ethanol plants and eleven months of our Fleischmann's Vinegar operations. The year ended December 31, 2019, includes eight months of operations of GPCC which are included in discontinued operations with the remaining four months of the GPCC joint venture being accounted for using the equity method of accounting. Additionally, operations of GPCC have been reclassified as discontinued operations and assets and liabilities of GPCC have been reclassified as assets and liabilities of discontinued operations in all prior periods presented.

Segment Results

We report the financial and operating performance for the following four operating segments: (1) ethanol production, which includes the production of ethanol, 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 operations and included vinegar production until the sale of Fleischmann's Vinegar during the fourth quarter of 2018 and (4) partnership, which includes fuel storage and transportation services.

During the normal course of business, our operating segments do business with each other. For example, our agribusiness and energy services segment procures grain and natural gas and sells products, including ethanol, distillers grains and corn oil of our ethanol production segment. Our partnership segment provides fuel storage and transportation services for our agribusiness and energy services 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 our consolidated results since the revenues and corresponding costs are eliminated.

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 and the gain on sale of assets, net recorded during the fourth quarter of 2018. When we evaluate segment performance, we review the following segment information as well as earnings before interest, income taxes, depreciation and amortization, or EBITDA, and adjusted EBITDA.

We use EBITDA and adjusted EBITDA as segment measures of profitability to compare the financial performance of our reportable segments and manage those segments. EBITDA is defined as earnings before interest expense, income tax expense, depreciation and amortization excluding the amortization of right-of-use assets. Adjusted EBITDA includes

adjustments related to operational results of Green Plains Cattle prior to its disposition which are recorded as discontinued operations and our proportional share of EBITDA adjustments of our equity method investees. We believe EBITDA and adjusted EBITDA are useful measures to compare our performance against other companies. EBITDA and adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income, which is prepared in accordance with GAAP. EBITDA and adjusted EBITDA calculations may vary from company to company. Accordingly, our computation of EBITDA and adjusted EBITDA may not be comparable with a similarly titled measure of other companies.

Year Ended December 31, 2019 Compared with the Year Ended December 31, 2018

Consolidated Results

Consolidated revenues decreased $566.7 million in 2019, compared with 2018 primarily due to the disposition of three ethanol plants and the sale of Fleischmann's Vinegar during the fourth quarter of 2018.

Operating income decreased $232.5 million and adjusted EBITDA decreased $260.9 million in 2019, compared with 2018 primarily due to gain on the sale of assets related to the sale of three ethanol plants and Fleischmann's Vinegar during the fourth quarter of 2018, which resulted in a net gain of $150.4 million as well as lower volumes and decreased margins on ethanol production in 2019. Interest expense decreased $47.2 million in 2019, compared with 2018 primarily due to the repayment of the $500 million senior secured term loan during the fourth quarter of 2018 and the deconsolidation of GPCC and elimination of the related revolver in the third quarter of 2019. Income tax benefit was $21.3 million in 2019, compared to $20.1 million in 2018. The change in income tax benefit is primarily due to a loss before income taxes in 2019, partially offset by the recognition of a valuation allowance of $25.3 million against the company's net deferred tax assets, while in 2018 we recorded the impact of R&D credits, net of FIN 48 reserves, of $19.8 million.

The following discussion provides greater detail about our segment performance.

Ethanol Production Segment

Key operating data for our ethanol production segment is as follows:



                                                 Year Ended December 31,
                                                 2019               2018
        Ethanol sold
        (thousands of gallons)                    856,623         1,086,633
        Distillers grains sold
        (thousands of equivalent dried tons)        2,234             2,815
        Corn oil sold
        (thousands of pounds)                     212,071           276,299
        Corn consumed
        (thousands of bushels)                    298,178           377,084

Revenues in the ethanol production segment decreased $419.9 million in 2019 compared with 2018 primarily due to the disposition of three ethanol plants during the fourth quarter of 2018 as well as lower production volumes of ethanol, distillers grains and corn oil due to the depressed margin environment and lower average realized prices for ethanol and distillers grains in 2019.

Cost of goods sold in the ethanol production segment decreased $327.7 million for 2019 compared with 2018 due to the disposition of three ethanol plants during the fourth quarter of 2018 as well as lower production volumes. As a result of the factors identified above, operating income decreased $66.8 million and EBITDA decreased $82.9 million during 2019. Depreciation and amortization expense for the ethanol production segment was $63.1 million for 2019, compared with $80.2 million during 2018 due to the sale of three ethanol plants during the fourth quarter of 2018.

Agribusiness and Energy Services Segment

Revenues in the agribusiness and energy services segment decreased $33.5 million while operating income decreased $6.3 million and EBITDA decreased $6.5 million in 2019 compared with 2018. The decrease in revenues was primarily due to a decrease in ethanol, distillers grain and corn oil production and trading activity, as well as lower average realized prices for ethanol. Operating income and EBITDA decreased primarily as a result of decreased margins.

Food and Ingredients Segment

Revenues in our food and ingredients segment decreased $119.7 million while operating income decreased by $14.4 million and EBITDA decreased $22.0 million during 2019, compared with 2018. The decrease in revenues, operating income and EBITDA was primarily due to the sale of Fleischmann's Vinegar outlined above.

Partnership Segment

Revenues generated from the partnership segment decreased $18.4 million in 2019 compared with 2018. Storage and throughput revenues decreased $12.1 million primarily due to a decrease in throughput volumes as a result the disposition of three ethanol plants in the fourth quarter of 2018. Revenues generated from rail transportation services decreased $4.8 million primarily due to the reduction in volumetric capacity provided as a result of the assignment of railcar operating leases as part of the disposition discussed above. Terminal services revenue decreased $0.8 million as a result of reduced throughput volume at our terminals. Trucking and other revenues decreased $0.6 million primarily due to a reduction in volumes transported for Green Plains Trade, partially offset by an increase in volumes transported for third party customers.

Operating income for the partnership segment decreased $14.1 million while EBITDA decreased $14.5 million in 2019 compared to 2018 due to the changes in revenues discussed above, partially offset by a decrease in operations and maintenance expenses of $5.2 million as a result of the factors identified above.

Intersegment Eliminations

Intersegment eliminations of revenues decreased by $24.7 million for 2019 compared with 2018 due to a decrease in storage and throughput fees paid to the partnership segment as well as decreased intersegment marketing fees within the agribusiness and energy services segment as a result of lower production volumes.

Corporate Activities

Operating income decreased by $135.2 million for 2019 compared with 2018, primarily due to the gain on sale of assets recorded during the fourth quarter of 2018.

Income Taxes

We recorded income tax benefit of $21.3 million for 2019 compared to $20.1 million in 2018. The change in income tax benefit is primarily due to a loss before income taxes in 2019, partially offset by the recognition of a $25.3 million valuation allowance against the company's net deferred tax assets, while in 2018 we recorded the impact of R&D credits, net of FIN 48 reserves, of $19.8 million. We increased the valuation allowance for our net deferred tax assets due to uncertainty that we will realize these assets in the future. The valuation allowance on deferred tax assets was recognized as a result of negative evidence, including cumulative losses in recent years, outweighing the more subjective positive evidence.

Net Income from Discontinued Operations

As previously discussed, we sold an aggregate 50% membership interest in GPCC to TGAM and StepStone during the third quarter of 2019. After closing, GPCC is no longer consolidated in our consolidated financial statements and the GPCC investment is accounted for using the equity method of accounting. GPCC results for all reported periods prior to its disposition are classified as discontinued operations. Net income from discontinued operations decreased by $10.7 million in 2019 primarily due to severe winter weather and abnormally negative basis during the first quarter of 2019.

Year Ended December 31, 2018 Compared with the Year Ended December 31, 2017

Consolidated Results

Consolidated revenues decreased $305.5 million in 2018, compared with 2017, primarily as a result of decrease in volumes for ethanol and distillers grains, lower average realized prices for ethanol and corn oil and lower revenues as a result of the disposition of three ethanol plants and Fleischmann's Vinegar in November of 2018, partially offset by higher average realized prices for distillers grains and additional natural gas volumes sold.

Operating income increased $66.2 million and adjusted EBITDA increased $71.3 million in 2018, compared with 2017 primarily due to gain on the sale of assets related to the sale of three ethanol plants and Fleischmann's Vinegar during the fourth quarter, which resulted in a net gain of $150.4 million. This increase was partially offset by decreased margins in our ethanol production segment. Interest expense increased $3.7 million in 2018, compared with 2017 primarily due to the $13.2 million write-off of deferred debt issuance costs related to repayment of the $500 million senior secured term loan due 2023, as well as higher average debt borrowings and higher borrowing costs during the year, partially offset by lower expense associated with termination of previous credit facilities during the fourth quarter of 2018. Income tax benefit was $20.1 million in 2018, compared to $132.1 million in 2017. The benefit reflected in 2018 is primarily due to the company's recognition of tax benefits related to the completion of the 2017 study for R&D credits and an estimate for 2018, as well as



                                       48

the effect of a lower tax rate on pre-tax income. The benefit reflected in 2017 is due to the company's recognition of tax benefits related to enactment of the Tax Cuts and Jobs Act and for the completion of a multi-year study for R&D Credits in 2017, as well as pre-tax losses at a higher tax rate.

The following discussion provides greater detail about our segment performance.

Ethanol Production Segment

Key operating data for our ethanol production segment is as follows:



                                                 Year Ended December 31,
                                                   2018             2017
         Ethanol sold
         (thousands of gallons)                   1,086,633       1,256,361
         Distillers grains sold
         (thousands of equivalent dried tons)         2,815           3,314
         Corn oil sold
         (thousands of pounds)                      276,299         301,920
         Corn consumed
         (thousands of bushels)                     377,084         437,373

Revenues in the ethanol production segment decreased $387.0 million in 2018 compared with 2017 primarily due to lower volumes of ethanol and distillers grains sold in addition to lower average ethanol and corn oil prices realized, partially offset by higher average distillers grains prices realized.

Cost of goods sold in the ethanol production segment decreased $315.2 million for 2018 compared with 2017 due to lower production volumes. As a result of the factors identified above, operating income decreased $66.7 million and EBITDA decreased $71.7 million during 2018. Depreciation and amortization expense for the ethanol production segment was $80.2 million for 2018, compared with $82.0 million during 2017 due to the sale of the three ethanol plants.

Agribusiness and Energy Services Segment

Revenues in the agribusiness and energy services segment increased $100.2 million while operating income decreased $1.4 million and EBITDA decreased $2.3 million in 2018 compared with 2017. The increase in revenues was primarily due to an increase in natural gas and ethanol trading activity, partially offset by lower average realized prices for corn oil. Operating income and EBITDA decreased primarily as a result of decreased margins.

Food and Ingredients Segment

Revenues in our food and ingredients segment decreased $21.8 million in 2018 compared with 2017. The decrease in revenues was primarily due to lower vinegar revenue due to the sale of Fleischmann's Vinegar during the fourth quarter of 2018.

Operating income decreased by $3.6 million and EBITDA decreased $5.4 million during 2018, compared with 2017 primarily due to a decrease in margins on corn oil and the sale of Fleischmann's Vinegar during the fourth quarter of 2018.

Partnership Segment

Revenues generated from the partnership segment decreased $6.2 million in 2018 compared with 2017. Revenues generated from rail transportation services decreased $3.9 million due to lower average rates charged for the railcar volumetric capacity provided, as well as the reduction in volumetric capacity associated with the assignment of railcar operating leases to Valero in the fourth quarter of 2018. Storage and throughput revenue decreased $3.2 million primarily due to a decrease in throughput volumes which was driven by lower capacity utilization, as well as the sale of the Bluffton, Indiana, Lakota, Iowa, and Riga Michigan ethanol plants. Revenues generated from terminal services decreased $0.8 million due to reduced throughput at our fuel terminals. These decreases were partially offset by an increase in trucking and other revenue of $1.6 million due to expansion of our truck fleet.

General and administrative expenses increased $1.0 million in 2018 compared with 2017 primarily due to higher transaction costs and professional fees, as well as an increase in expenses allocated to the partnership under the secondment agreement.

--------------------------------------------------------------------------------

Table of Contents

Operating income for the partnership segment decreased $0.9 million while EBITDA decreased $1.6 million in 2018 compared to 2017 due to the changes in revenues discussed above, partially offset by a decrease in operations and maintenance expenses of $2.6 million as a result of the factors identified above.

Intersegment Eliminations

Intersegment eliminations of revenues decreased by $9.3 million for 2018 compared with 2017, primarily due a decrease in storage and throughput fees paid to the partnership as a result of the sale of three ethanol plants in November 2018.

Corporate Activities

Operating income was impacted by a decrease in operating expenses for corporate activities of $141.9 million for 2018 compared with 2017, primarily due to the gain on sale of assets recorded during the fourth quarter of 2018.

Income Taxes

We recorded income tax benefit of $20.1 million for 2018 compared to $132.1 million in 2017. The benefit reflected in 2018 is primarily due to the company's recognition of tax benefits related to the completion of the 2017 study for R&D credits and an estimate for 2018, as well as the effect of a lower tax rate on pre-tax income. The benefit reflected in 2017 is primarily due to the company's recognition of tax benefits related to enactment of the Tax Cuts and Jobs Act and for the completion of a multi-year study for R&D Credits in 2017, as well as pre-tax losses at a higher tax rate.

Net Income from Discontinued Operations

As previously discussed, we sold an aggregate 50% membership interest in GPCC to TGAM and StepStone 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. GPCC results for all prior periods are classified as discontinued operations. Net income from discontinued operations increased by $6.5 million in 2018 primarily due to an increase in volumes sold as a result of the acquisitions of cattle feeding operations during the first and second quarters of 2017 and in the third quarter of 2018. In addition, during 2018, the company recognized a gain within other income of $4.5 million related to business interruption and property insurance proceeds received in excess of the book value of certain fixed assets that were damaged at the Hereford cattle feed yard.

Liquidity and Capital Resources

Our principal sources of liquidity include cash generated from operating activities and bank credit facilities. We fund our operating expenses and service debt primarily with operating cash flows. Capital resources for maintenance and growth expenditures are funded by a variety of sources, including cash generated from operating activities, borrowings under bank credit facilities, or issuance of senior notes or equity. Our ability to access capital markets for debt under reasonable terms depends on our financial condition, credit ratings and market conditions. We believe that our ability to obtain financing at reasonable rates and history of consistent cash flow from operating activities provide a solid foundation to meet our future liquidity and capital resource requirements.

On December 31, 2019, we had $246.0 million in cash and equivalents, excluding restricted cash, consisting of $177.1 million available to our parent company and the remainder at our subsidiaries. Additionally, we had $23.9 million in restricted cash at December 31, 2019. We also had $289.7 million available under our committed revolving credit agreements, some of which were subject to restrictions or other lending conditions. Funds held by our subsidiaries are generally required for their ongoing operational needs and restricted from distribution. At December 31, 2019, our subsidiaries had approximately $67.4 million of net assets that were not available to use in the form of dividends, loans or advances due to restrictions contained in their credit facilities.

Net cash used in operating activities of continuing operations was $27.0 million in 2019 compared with net cash provided by operating activities of continuing operations of $29.5 million in 2018. Operating activities compared to the prior year were primarily affected by the decrease in operating income as well as changes to working capital. Net cash provided by investing activities of continuing operations was $34.8 million in 2019, compared to net cash provided by investing activities of continuing operations of $635.5 million in 2018 due primarily to the proceeds from the sale of the three ethanol plants and Fleischmann's Vinegar during 2018. Net cash used in financing activities of continued operations was $18.9 million in 2019, compared to $643.6 million in 2018 primarily due to the repayment of the term loan during 2018.

Additionally, Green Plains Trade and Green Plains Grain use revolving credit facilities to finance working capital requirements. We frequently draw from and repay these facilities which results in significant cash movements reflected on a gross basis within financing activities as proceeds from and payments on short-term borrowings.

We incurred capital expenditures of $76.5 million in 2019 primarily related to our high-protein and Project 24 initiatives. The current projected estimate for capital spending for 2020 is approximately $80 million to $120 million, which is subject to review prior to the initiation of any project. The budget includes additional expenditures for our high-protein and Project 24 initiatives, as well as expenditures for various other maintenance projects, and is expected to be financed with available borrowings under our credit facilities and cash provided by operating activities, as well as additional borrowings as needed.

Our business is highly sensitive to the price of commodities, particularly for corn, ethanol, distillers grains, corn oil and natural gas. We use derivative financial instruments to reduce the market risk associated with fluctuations in commodity prices. Sudden changes in commodity prices may require cash deposits with brokers for margin calls or significant liquidity with little advanced notice to meet margin calls, depending on our open derivative positions. On December 31, 2019, we had $12.2 million in margin deposits for broker margin requirements included in the balance of restricted cash. We continuously monitor our exposure to margin calls and believe we will continue to maintain adequate liquidity to cover margin calls from our operating results and borrowings.

On June 18, 2019, we announced that our board of directors decided to suspend future quarterly cash dividends following the June 14, 2019 dividend payment, in order to retain and redirect cash flow to the our Project 24 operating expense equalization plan, the deployment of high-protein technology and our stock repurchase program.

On October 30, 2019, our board of directors authorized an additional $100.0 million share repurchase taking the previously authorized amount from $100.0 million to $200.0 million. Under the program, we may repurchase shares in open market transactions, privately negotiated transactions, accelerated share buyback programs, tender offers or by other means. The timing and amount of repurchase transactions are determined by our management based on market conditions, share price, legal requirements and other factors. The program may be suspended, modified or discontinued at any time without prior notice. During 2019, we purchased a total of 5,396,608 shares of common stock for approximately $61.6 million. As of December 31, 2019, we have repurchased 6,515,957 of common stock for approximately $81.4 million under the program.

The requirements under the partnership agreement for the conversion of all of the outstanding subordinated units into common units were satisfied upon the payment of the distribution with respect to the quarter ended June 30, 2018. Accordingly, the subordination period ended on August 13, 2018, the first business day after the date of the distribution payment, and all of the 15,889,642 outstanding subordinated units were converted into common units on a one-for-one basis. The conversion of the subordinated units does not impact the amount of cash distributions paid or the total number of outstanding units.

On December 27, 2019, we filed a shelf registration statement on Form S-3 with the SEC, declared effective January 7, 2020, registering an indeterminate number of shares of common stock, warrants and debt securities up to $250,000,000.

We believe we have sufficient working capital for our existing operations. Furthermore, our liquidity position has improved as a result of the partial sale of GPCC during the third quarter of 2019 and the sale of our 50% joint venture interest in JGP Energy Partners LLC during the fourth quarter of 2019, in addition to the sale of three of our ethanol plants and Fleischmann's Vinegar during the fourth quarter of 2018. The majority of net cash proceeds from the sales of three of our ethanol plants and Fleischmann's Vinegar, net of fees and taxes, were used to pay off the outstanding term loan balance. Net cash proceeds from the partial sale of GPCC and the sale of our interest in JGP Energy Partners LLC were used towards our continued investment into our high-protein initiative, to repurchase the company's common stock as part of our share repurchase program and general corporate purposes. A continued sustained period of unprofitable operations, however, may strain our liquidity. We may sell additional assets or equity or borrow capital to improve or preserve our liquidity, expand our business or acquire businesses. We cannot provide assurance that we will be able to secure funding necessary for additional working capital or these projects at reasonable terms, if at all.

Debt

We were in compliance with our debt covenants at December 31, 2019. Based on our forecasts, we believe we will maintain compliance at each of our subsidiaries for the next twelve months or have sufficient liquidity available on a consolidated basis to resolve noncompliance. We cannot provide assurance that actual results will approximate our forecasts or that we will inject the necessary capital into a subsidiary to maintain compliance with its respective covenants. In the event a subsidiary is unable to comply with its debt covenants, the subsidiary's lenders may determine that an event of default has occurred, and following notice, the lenders may terminate the commitment and declare the unpaid balance due and payable.

As outlined in Note 12 - Debt, we use LIBOR as a reference rate for certain revolving credit facilities. LIBOR is currently set to be phased out at the end of 2021. At this time, it is not possible to predict the effect of this change or the alternative reference rate to be used. We will need to renegotiate certain credit facilities to determine the interest rate to replace LIBOR with the new standard that is established. As such, the potential effect of any such event on interest expense cannot yet be determined.

Corporate Activities

On June 21, 2019, we issued $105.0 million of 4.00% convertible senior notes due in 2024, or the 4.00% notes. We used approximately $57.8 million of the net proceeds to repurchase the $56.8 million outstanding principal amount of its 3.25% convertible senior notes due October 1, 2019 in cash, including accrued and unpaid interest, in privately negotiated transactions concurrently with the offering of 4.00% notes. On July 19, 2019, we closed on the issuance of an additional $10.0 million aggregate principal amount of the 4.00% notes (the "Option Notes") to the initial purchasers. The Option Notes provided us with net proceeds, after deducting commissions and our offering expenses, of approximately $9.5 million. The Option Notes have the same terms as the 4.00% notes issued on June 21, 2019, and were issued under the same Indenture dated as of June 21, 2019. After the issuance of the Option Notes, total aggregate principal of the 4.00% notes outstanding is $115.0 million.

The 4.00% notes are senior, unsecured obligations, 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 initial conversion rate will be 64.1540 shares of our common stock per $1,000 principal amount of the 4.00% notes, which is equivalent to an initial conversion price of approximately $15.59 per share of our common stock. The conversion rate will be subject to adjustment upon the occurrence of certain events. In addition, we may be obligated to increase the conversion rate for any conversion that occurs in connection with certain corporate events, including our calling the 4.00% notes for redemption. We may settle the 4.00% notes in cash, common stock or a combination of cash and common stock. At December 31, 2019, the outstanding principal balance was $83.5 million on the 4.00% notes.

In August 2016, we issued $170.0 million of 4.125% convertible senior notes due in 2022, or 4.125% notes, which are senior, unsecured obligations with interest payable on March 1 and September 1 of each year. 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 when the quarterly cash dividend exceeds $0.12 per share. We may settle the 4.125% notes in cash, common stock or a combination of cash and common stock. At December 31, 2019, the outstanding principal balance was $149.3 million on the 4.125% notes.

Ethanol Production Segment

We have small equipment financing loans, capital 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 up to the maximum commitment based on eligible collateral, which matures in July of 2022. This facility can be increased by up to $70.0 million with agent approval. Advances are subject to variable interest rates equal to a daily LIBOR rate plus 2.25% or the base rate plus 1.25%. The unused portion of the credit facility is also subject to a commitment fee of 0.375% per annum. At December 31, 2019, the outstanding principal balance was $138.2 million on the facility and the interest rate was 3.86%.

Green Plains Grain has a $100.0 million senior secured asset-based revolving credit facility to finance working capital up to the maximum commitment based on eligible collateral, which matures in June of 2022. This facility can be increased by an additional $75.0 million with agent approval and up to $50.0 million for seasonal borrowings. Total commitments outstanding under the facility cannot exceed $225.0 million. On June 28, 2019, the company amended the credit facility to extend the existing maturity date from July 26, 2019 to June 28, 2022 and lower the maximum commitment from $125.0 million to $100.0 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% per annum. At December 31, 2019, the outstanding principal balance was $40.0 million and the interest rate was 6.75%. The average interest rate for fiscal 2019 was 5.62%.

Green Plains Grain has short-term inventory financing agreements with a financial institution with a maximum commitment of up to $50.0 million, which matures June 2022. Green Plains Grain has accounted for the agreements as short-



                                       52

term notes, rather than sales, and has elected the fair value option to offset fluctuations in market prices of the inventory. Green Plains Grain had no short-term notes payable related to these inventory financing agreements as of December 31, 2019.

Green Plains Commodity Management has an uncommitted revolving credit facility, which was amended in October 2019, to increase the maximum commitment from $20.0 million to $30.0 million. The revolving credit facility, which matures April 30, 2023, is used to finance margins related to its hedging programs. Advances are subject to variable interest rates equal to LIBOR plus 1.75%. At December 31, 2019, the outstanding principal balance was $9.6 million and the interest rate was 3.38%.

Food and Ingredients Segment

Upon the disposition of Green Plains Cattle, the food and ingredient segment no longer has any forms of debt financing. Refer to Note 5 - Acquisitions, Dispositions and Discontinued Operations for further discussion on the disposition and discontinued operations classification.

Partnership Segment

Green Plains Partners, through a wholly owned subsidiary, has a $200.0 million revolving credit facility to fund working capital, acquisitions, distributions, capital expenditures and other general partnership purposes. The credit facility matures on July 1, 2020, and as a result, was reclassified to current maturities of long-term debt. We intend to renew and extend the revolving credit facility with similar terms prior to its maturity. The credit facility can be increased by an additional $20.0 million without the consent of the lenders. At December 2019, the outstanding principal balance of the facility was $132.1 million and the interest rate was 4.79%.

While the partnership has not yet renegotiated the credit facility or secured additional funding necessary to repay the loan, the partnership believes it is probable that it will source appropriate funding given the partnership's consistent and stable fee-based cash flows, ongoing profitability, low debt leverage and history of obtaining financing on reasonable commercial terms. In the unlikely scenario that the partnership is unable to refinance its debt with the lenders prior to its maturity, the partnership will consider other financing sources, including but not limited to, the restructuring or issuance of new debt with a different lending group, the issuance of additional partnership units or support from Green Plains Inc.

Refer to Note 12 - Debt included as part of the notes to consolidated financial statements for more information about our debt.

Contractual Obligations

Contractual obligations as of December 31, 2019 were as follows (in thousands):
