	·	Aemetis Biogas LLC, a Delaware limited liability company; and
	·	Goodland Advanced Fuels, Inc., a Nevada corporation.

Nature of Activities. Founded in 2006 and headquartered in Cupertino, California, Aemetis, Inc. (collectively with its subsidiaries on a consolidated basis, “Aemetis,” the “Company,” “we,” “our” or “us”) is an international renewable fuels and byproducts company focused on the acquisition, development and commercialization of innovative technologies that replace traditional petroleum-based products.

We own and operate a 65 million gallon per year ethanol production facility located in Keyes, California (the “Keyes Plant”). In addition to low carbon renewable fuel ethanol, the Keyes Plant produces Wet Distillers Grains (“WDG”), Distillers Corn Oil (“DCO”), and Condensed Distillers Solubles (“CDS”), all of which are sold as animal feed to local dairies and feedlots. In the fourth quarter of 2021, an ethanol zeolite membrane dehydration system was installed at the Keyes Plant and is in process of being commissioned at the Keyes Plant, a key first step in the electrification of the Keyes facility.

During 2018, Aemetis Biogas, LLC (“ABGL”) was formed to construct bio-methane anaerobic digesters at local dairies near the Keyes Plant, many of whom also purchase WDG produced at the Keyes Plant. Our Dairy Renewable Natural Gas segment, ABGL, has completed Phase 1 of our California biogas digester network and pipeline system that converts waste dairy methane gas into Dairy Renewable Natural Gas (“RNG”) and is now executing Phase 2 construction. The digesters are connected via an underground private pipeline owned by ABGL to a gas cleanup and compression unit being built at the Keyes Plant to produce RNG. During the third quarter of 2020, ABGL completed construction of the first two dairy digesters along with four miles of pipeline that carries bio-methane from the dairies to the Keyes Plant. Upon receiving the bio-methane from the dairies, impurities are removed, and the bio-methane is converted to negative carbon intensity RNG where it will be either be sold to third parties or used as renewable process energy at the Keyes Plant.

During the first quarter of 2021, we announced our “Carbon Zero” biofuels production plants designed to produce biofuels, including sustainable aviation fuel (“SAF”) and diesel fuel utilizing renewable hydrogen and non-edible renewable oils sourced from our existing biofuels plants and other sources. The first plant, in Riverbank, California, “Carbon Zero 1”, is expected to utilize hydroelectric and other renewable power available onsite to produce SAF, renewable diesel, and other byproducts. The plant is expected to supply the aviation and truck markets with ultra-low carbon renewable fuels.

On April 1, 2021, we established Aemetis Carbon Capture, Inc. to build Carbon Capture and Sequestration (CCS) projects to generate LCFS and IRS 45Q credits by injecting CO₂ into wells which are monitored for emissions to ensure the long-term sequestration of carbon underground.

During 2017, Goodland Advanced Fuels, Inc. (“GAFI”) was formed to acquire land, buildings and process equipment in Goodland, Kansas for the construction and development of a next generation biofuel facility for $15.4 million. GAFI entered into a Note Purchase Agreement with Third Eye Capital Corporation (“Third Eye Capital”). On December 31, 2019, we exercised an option to acquire all capital stock of GAFI for $10 and consolidated assets, liabilities, and equity. In addition, the period costs related to non-controlling interest are presented as separately on the Statement of Operations for the year ended December 31, 2019. Prior to December 31, 2019, GAFI was consolidated into the financial statements as a variable interest entity.

We also own and operate the Kakinada Plant with a nameplate capacity of 150 thousand metric tons per year, or about 50 million gallons per year, producing high quality distilled biodiesel and refined glycerin for customers in India and Europe. The Kakinada Plant is capable of processing a variety of vegetable oils and animal fat waste feedstocks into biodiesel that meet international product standards. The Kakinada Plant also distills the crude glycerin byproduct from the biodiesel refining process into refined glycerin, which is sold to the pharmaceutical, personal care, paint, adhesive and other industries.

Basis of Presentation and Consolidation. These consolidated financial statements include the accounts of Aemetis. Additionally, we consolidate all entities in which we have a controlling financial interest. A controlling financial interest is usually obtained through ownership of a majority of the voting interests. However, an enterprise must consolidate a variable interest entity (“VIE”) if the enterprise is the primary beneficiary of the VIE, even if the enterprise does not own a majority of the voting interests. The primary beneficiary is the party that has both the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and the obligation to absorb losses or the right to receive benefits from the VIE that could potentially be significant to the VIE. ABGL was assessed to be a VIE and through the Company's ownership interest in all of the outstanding common stock, the Company has been determined to be the primary beneficiary and accordingly, the assets, liabilities, and operations of ABGL are consolidated into those of the Company.

Prior to December 31, 2019, GAFI was consolidated into the financial statements as a VIE. We concluded that GAFI did not have enough equity to finance its activities without additional subordinated financial support and GAFI’s shareholder did not have a controlling financial interest in the entity. Through providing a Limited Guaranty, pursuant to which, the Guarantors agreed to guarantee the prompt payment and performance of all unpaid principal and interest on the GAFI Loans and all other obligations and liabilities of GAFI to the GAFI Noteholders in connection with the GAFI Note Purchase Agreement, and signing the Option Agreement, pursuant to which the Company was granted an irrevocable option to purchase all, but not less than all, of the capital stock of GAFI for an aggregate purchase price equal to $0.01 per share for a total purchase price of $10.00, the Company took the risks related to operations, financing the Goodland Plant, and agreed to meet the financial covenants for GAFI to be in existence. Based upon this assessment, Aemetis has the power to direct the activities of GAFI and has been determined to be the primary beneficiary of GAFI and accordingly, the assets, liabilities, and operations of GAFI are consolidated into those of the Company. The assets and liabilities were initially recognized at fair value. On December 31, 2019, we exercised an option to acquire all capital stock of GAFI and consolidated it with the Company.

All intercompany balances and transactions have been eliminated in consolidation.

Use of Estimates. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the reporting period. To the extent there are material differences between these estimates and actual results, the Company’s consolidated financial statements will be affected.

Revenue Recognition. We derive revenue primarily from sales of ethanol, high-grade alcohol and related co-products in California Ethanol and India biodiesel and refined glycerin in India pursuant to supply agreements and purchase order contracts. We assessed the following criteria under the ASC 606 guidance: (i) identify the contracts with customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when the entity satisfies the performance obligations.

California Ethanol: Until May 13, 2020, we sold all our ethanol to J.D. Heiskell & Co. (“J.D. Heiskell”) under the Working Capital and Purchasing Agreement (the “J.D. Heiskell Purchasing Agreement”). On May 13, 2020, we entered into an amendment to the Corn Procurement and Working Capital Agreement with J.D. Heiskell (the “Corn Procurement and Working Capital”), under the terms of which we buy all corn from J.D. Heiskell and sell all WDG and corn oil we produce to J.D. Heiskell. Following May 13, 2020 and until October, 2021, we sold the majority of our fuel ethanol production to one customer, Kinergy Marketing, LLC (“Kinergy”), through individual sales transactions. We terminated the Ethanol Marketing Agreement with Kinergy as of September 30, 2021. Effective October 1, 2021, we entered into Fuel Ethanol Purchase and Sale Agreement with Murex LLC (“Murex”), in which we will sell all our Ethanol to Murex. Given the similarity of the individual sales transactions with Kinergy and Murex, we have assessed them as a portfolio of similar contracts. The performance obligation is satisfied by delivery of the physical product to one of our customer’s contracted trucking companies. Upon delivery, the customer has the ability to direct the use of the product and receive substantially all of its benefits. The transaction price is determined based on daily market prices negotiated by Kinergy and Murex for ethanol and by our marketing partner A.L. Gilbert Company (“A.L. Gilbert”) for WDG. The transaction price is allocated to one performance obligation.

During the first quarter of 2020, Aemetis began selling high-grade alcohol for consumer applications directly to customers on the West Coast and Midwest using a variety of payment terms. These agreements and terms were evaluated according to ASC 606 guidance and such revenue is recognized upon satisfaction of the performance obligation by delivery of the product based on the terms of the agreement. Sales of high-grade alcohol were minimal for 2021 and were aggregated with ethanol sales. Sales of high-grade alcohol represented 0%, 15%, and 0% of revenue for the years ended December 31, 2021, 2020, and 2019, respectively.

The below table shows our sales in California Ethanol by product category:

California Ethanol	For the twelve months ended December 31,
	2021		2020		2019
Ethanol and high-grade alcohol sales	$	162,428	$	111,219	$	114,593
Wet distiller's grains sales		41,476		32,048		34,510
Other sales		7,347		6,035		5,045
	$	211,251	$	149,302	$	154,148

We have elected to adopt the practical expedient that allows for ignoring the significant financing component of a contract when estimating the transaction price when the transfer of promised goods to the customer and customer payment for such goods are expected to be within one year of contract inception. Further, we have elected to adopt the practical expedient in which incremental costs of obtaining a contract are expensed when the amortization period would otherwise be less than one year.

We also assessed principal versus agent criteria as we buy our feedstock from our customers and process and sell finished goods to those customers in some contractual agreements.

For our California Ethanol segment, we buy corn as feedstock for the production of ethanol, from our working capital partner J.D. Heiskell. Prior to May 13, 2020, we sold all our ethanol, WDG, and corn oil to J.D. Heiskell and we bought all our corn to process into ethanol from J.D. Heiskell. After May 13, 2020, we sold most of our fuel ethanol to one customer, Kinergy, and sold all WDG and corn oil to J.D. Heiskell. During the second quarter of 2021, the Company signed a biofuels offtake agreement with Murex, LLC, and beginning on October 1, 2021 the Company sold all our fuel ethanol to Murex LLC. We only have customer relationships with Kinergy Marketing and Murex LLC, hence the principal and agent criteria is not applied. However, we are still buying corn and selling WDG and corn oil to J.D.Heiskell, we analyzed the principal vs agent relationship criteria below.

We consider the purchase of corn as a cost of goods sold and the sale of WDG, corn oil, upon trucks leave the Keyes Plant, as revenue on the basis that (i) we control and bear the risk of gain or loss on the processing of corn which is purchased at market prices into ethanol and (ii) we have legal title to the goods during the processing time. The pricing for both corn WDG, and Corn oil is set independently. Revenues from WDG and Corn oil are billed net of the related transportation and marketing charges. The transportation component is accounted for in cost of goods sold and the marketing component is accounted for in sales, general and administrative expense. Transportation and marketing charges are known within days of the transaction and are recorded at the actual amounts. The Company has elected an accounting policy under which these charges have been treated as fulfillment activities provided after control has transferred. As a result, these charges are recognized in cost of goods sold and selling, general and administrative expenses, respectively, when revenue is recognized. Revenues are recorded at the gross invoiced amount. Hence, we are the principal in California Ethanol segment where our customer and vendor may be the same.

We have a contract liability of $0 and $0.2 million as of December 31, 2021 and 2020.

Dairy Renewable Natural Gas: All of our Dairy Renewable Natural Gas segment revenues during the years ended December 31, 2021 and 2020 were from sales of biogas to the Keyes Plant for use in boilers. This resulted in lowering the carbon intensity of the Keyes Plant and increased revenues on ethanol sold through the California Ethanol segment. These revenues have been eliminated once consolidated. Refer to Footnote 12 Segment Information for Dairy Renewable Natural Gas for the unconsolidated revenue.

India Biodiesel: We sell products pursuant to purchase orders (written or verbal) or by contract with governmental or international parties, in which performance is satisfied by delivery and acceptance of the physical product. Given that the contracts are sufficiently similar in nature, we have assessed these contracts as a portfolio of similar contracts as allowed under the practical expedient. Doing so does not result in a materially different outcome compared to individually accounting for each contract. All domestic and international deliveries are subject to certain specifications as identified in contracts. The transaction price is determined daily based on reference market prices for biodiesel, refined glycerin, and PFAD net of taxes. Transaction price is allocated to one performance obligation.

The below table shows our sales in India by product category:

India Biodiesel (in thousands) For the twelve months ended December 31, 2021 2020 2019 Biodiesel sales $465 $13,796 $42,464 Refined glycerin sales 125 1,172 2,809 PFAD sales - 774 2,557 Other sales 106 53 20 $696 $15,795 $47,850

In India, we also assessed principal versus agent criteria as we buy our feedstock from our customers and process and sell finished goods to those same customers in certain contractual agreements. In those cases, we receive the legal title to feedstock from our customers once it is on our premises. We control the processing and production of biodiesel based on contract terms and specifications. The pricing for both feedstock and biodiesel is set independently. We hold the title and risk to biodiesel according to agreements we enter into in these situations. Hence, we are the principal in India Biodiesel sales scenarios where our customer and vendor may be the same.

Cost of Goods Sold. Cost of goods sold includes those costs directly associated with the production of revenues, such as raw material consumed, factory overhead and other direct production costs. During periods of idle plant capacity, costs otherwise charged to cost of goods sold are reclassified to selling, general and administrative expense. The company recorded, in cost of goods sold, in the year ended December 31, 2021, approximately $5.0 million related to our California triennial obligation on GHG emissions, of which approximately $3.2 million relates to periods prior to 2021 and is considered insignificant.

Shipping and Handling Costs. Shipping and handling costs are classified as a component of cost of goods sold in the accompanying consolidated statements of operations.

Research and Development. Research and development costs are expensed as incurred, unless they have alternative future uses to the Company.

Cash and Cash Equivalents. The Company considers all highly liquid investments with an original maturity of three months or less to be cash equivalents. The Company maintains cash balances at various financial institutions domestically and abroad. The Federal Deposit Insurance Corporation insures domestic cash accounts. The Company’s accounts at these institutions may at times exceed federally insured limits. The Company has not experienced any losses in such accounts.

Accounts Receivable. The Company sells ethanol and WDG through third-party marketing arrangements generally without requiring collateral and high-grade alcohol directly to customers on a variety of terms including advanced payment terms, based on the size and creditworthiness of the customer. DCO is marketed and sold to A.L. Gilbert under the J.D. Heiskell Purchasing Agreement. The Company sells CDS directly to customers on standard 30 day payment terms. The Company sells biodiesel, glycerin, and processed natural oils to a variety of customers and may require advanced payment based on the size and creditworthiness of the customer. Usually, invoices are due within 30 days on net terms. Accounts receivables mostly consist of product sales made to large creditworthy customers. Trade accounts receivable are presented at original invoice amount, net of any allowance for doubtful accounts.

The Company maintains an allowance for doubtful accounts for balances that appear to have specific collection issues. The collection process is based on the age of the invoice and requires attempted contacts with the customer at specified intervals. If, after a specified number of days, the Company has been unsuccessful in its collection efforts, a bad debt allowance is recorded for the balance in question. Delinquent accounts receivables are charged against the allowance for doubtful accounts once un-collectability has been determined. The factors considered in reaching this determination are the apparent financial condition of the customer and the Company’s success in contacting and negotiating with the customer. If the financial condition of the Company’s customers were to deteriorate, additional allowances may be required. We reserved $1.4 million and $1.3 million in the allowances for doubtful accounts as of December 31, 2021 and December 31, 2020, respectively.

Inventories. Finished goods, raw materials, and work-in-process inventories are valued using methods which approximate the lower of cost (first-in, first-out) or net realizable value (NRV). Distillers’ grains and related products are stated at NRV. In the valuation of inventories, NRV is determined as estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The company periodically reviews the value of items in inventory and provides write-downs or write-offs of inventory based on its assessment of market conditions. Write-downs and write-offs are charged to cost of goods sold. For the years ended December 31, 2021, 2020 and 2019, the company experienced total write-offs of $1.0 million, none and none.

Variable Interest Entities. We determine at the inception of each arrangement whether an entity in which we have made an investment or in which we have other variable interests in is considered a variable interest entity (VIE). We consolidate VIEs when we are the primary beneficiary. The primary beneficiary of a VIE is the party that meets both of the following criteria: (1) has the power to make decisions that most significantly affect the economic performance of the VIE; and (2) has the obligation to absorb losses or the right to receive benefits that in either case could potentially be significant to the VIE. Periodically, we assess whether any changes in our interest or relationship with the entity affect our determination of whether the entity is still a VIE and, if so, whether we are the primary beneficiary. If we are not the primary beneficiary in a VIE, we account for the investment or other variable interests in a VIE in accordance with applicable GAAP.

Property, Plant and Equipment. Property, plant, and equipment are carried at cost less accumulated depreciation after assets are placed in service and are comprised primarily of buildings, furniture, machinery, equipment, land, biogas dairy digesters, and the Keyes Plant, Goodland Plant and Kakinada Plant. The Goodland Plant is partially completed and is not ready for operation. The first two dairy digesters and pipeline in the Biogas Project were completed, commissioned and began to be depreciated during the third quarter of 2020. The CO₂ Project was completed and commenced operations in the second quarter of 2020. Accordingly, any assets under the CO₂ Project began being depreciated starting in May 2020. It is the Company’s policy to depreciate capital assets over their estimated useful lives using the straight-line method.

The Company evaluates the recoverability of long-lived assets with finite lives in accordance with ASC Subtopic 360-10-35 Property Plant and Equipment –Subsequent Measurement, which requires recognition of impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of asset groups may not be recoverable. When events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable, based on estimated undiscounted cash flows, the impairment loss would be measured as the difference between the carrying amount of the asset group and its estimated fair value. The Company has not recorded any impairment as of December 31, 2021, 2020, and 2019.

California Energy Commission Technology Demonstration Grant. The Company has been awarded and completed the demonstration project associated with the $825 thousand matching grant program from the California Energy Commission (“CEC”) Natural Resources Agency to optimize the effectiveness of technologies to break down biomass to produce cellulosic ethanol. The Company has received all of the awarded grant proceeds as of December 31, 2020. The project focused on the deconstruction and conversion of sugars liberated from California-relevant feedstocks and then converting the sugars to ethanol. The Company receives these funds as reimbursement for actual expenses incurred. Due to the uncertainty associated with the expense approval process under the grant program, the Company recognized the grant as a reduction of the expenses in the period when payment is received.

California Energy Commission Low-Carbon Fuel Production Program. The Company has been awarded $4.2 million in matching grants from the California Energy Commission Low-Carbon Fuel Production Program (“LCFPP”). The LCFPP grant reimburses the Company for costs to design, procure, and install processing facility to clean-up, measure and verify negative-carbon intensity dairy renewable natural gas fuel at the production facility in Keyes, California. The Company has received $2.9 million from the LCFPP as of December 31, 2021 as reimbursement for actual costs incurred. Due to the uncertainty associated with the approval process under the grant program, the Company recognizes the grant as a reduction of the costs in the period when payment is received.

California Department of Food and Agriculture Dairy Digester Research and Development Grant. In 2019, the Company was awarded $3.2 million in matching grants from the California Department of Food and Agriculture (“CDFA”) Dairy Digester Research and Development program. The CDFA grant reimburses the Company for costs required to permit and construct two of the Company’s biogas capture systems under contract with central California dairies. The Company received all the awarded grant proceeds as of the second quarter 2021.

In October 2020, the Company was awarded $7.8 million in matching grants from the CDFA Dairy Digester Research and Development program. The CDFA grant reimburses the Company for costs required to permit and construct six of the Company’s biogas capture systems under contract with central California dairies. The Company has received $545 thousand from the CDFA 2020 grant program as of December 31, 2021 as reimbursement for actual costs incurred. Due to the uncertainty associated with the approval process under the grant program, the Company recognizes the grant as a reduction of the costs in the period when payment is received.

California Energy Commission Low Carbon Advanced Ethanol Grant Program. In May 2019, the Company was awarded the right to receive reimbursements from the California Energy Commission Community-Scale and Commercial-Scale Advanced Biofuels Production Facilities grant under the Alternative and Renewable Fuel and Vehicle Technology Program in an amount up to $5.0 million (the “CEC Reimbursement Program”) in connection with the Company’s expenditures toward the development of the Riverbank Carbon Zero 1 plant. To comply with the guidelines of the CEC Reimbursement Program, the Company must make a minimum of $7.9 million in matching contributions to the Riverbank project. The Company receives funds under the CEC Reimbursement Program for actual expenses incurred up to $5.0 million as long as the Company makes the minimum matching contribution. Given that the Company has not made the minimum matching contribution, the grant for reimbursement of capital expenditures of $1.8 million and $1.7 million and is presented with long-term liabilities as of December 31, 2021 and 2020. Due to the uncertainty associated with meeting the minimum matching contribution, the reimbursement will be recognized when the Company makes the minimum matching contribution.

Income Taxes. The Company recognizes income taxes in accordance with ASC 740 Income Taxes using an asset and liability approach. This approach requires the recognition of taxes payable or refundable for the current year and deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. The measurement of current and deferred taxes is based on provisions of enacted tax law.

ASC 740 provides for recognition of deferred tax assets if the realization of such assets is more likely than not to occur. Otherwise, a valuation allowance is established for the deferred tax assets, which may not be realized. As of December 31, 2021 and 2020, the Company recorded a full valuation allowance against its U.S. federal and state net deferred tax assets due to operating losses incurred since inception. Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets were fully offset by a valuation allowance.

The Company is subject to income tax audits by the respective tax authorities in all of the jurisdictions in which it operates. The determination of tax liabilities in each of these jurisdictions requires the interpretation and application of complex and sometimes uncertain tax laws and regulations. The recognition and measurement of current taxes payable or refundable and deferred tax assets and liabilities requires that the Company make certain estimates and judgments. Changes to these estimates or a change in judgment may have a material impact on the Company’s tax provision in a future period.

In 2018, the Company adopted certain tax accounting policies related to the new global intangible low-taxed income (“GILTI”) provisions under the Tax Act such that the Company will: (1) account for all GILTI related book-tax differences as period costs and (2) use the Incremental Cash Tax Savings approach in evaluating its valuation allowance assessment related to the GILTI inclusion.

Basic and Diluted Net Income (Loss) per Share. Basic net income (loss) per share is computed by dividing net income or loss attributable to common shareholders by the weighted average number of common shares outstanding for the period. Diluted net income (loss) per share reflects the dilution of common stock equivalents such as options, convertible preferred stock, debt and warrants to the extent the impact is dilutive. As the Company incurred a net loss for the years ended December 31, 2021, 2020 and 2019, potentially dilutive securities have been excluded from the diluted net loss per share computations as their effect would be anti-dilutive.

The following table shows the number of potentially dilutive shares excluded from the diluted net loss per share calculation as of December 31, 2021, 2020, and 2019:

	As of
	December 31, 2021		December 31, 2020		December 31, 2019

Series B preferred (post split basis)		128		132		132
Common stock options and warrants		3,819		5,422		3,840
Debt with conversion feature at $30 per share of common stock		1,220		1,298		1,262

Total number of potentially dilutive shares excluded from the diluted net (loss) per share calculation		5,167		6,852		5,234

Comprehensive Loss. ASC 220 Comprehensive Income requires that an enterprise report, by major components and as a single total, the change in its net assets from non-owner sources. The Company’s other comprehensive loss and accumulated other comprehensive loss consists solely of cumulative currency translation adjustments resulting from the translation of the financial statements of its foreign subsidiary. The investment in this subsidiary is considered indefinitely invested overseas, and as a result, deferred income taxes are not recorded related to the currency translation adjustments.

Foreign Currency Translation/Transactions. Assets and liabilities of the Company’s non-U.S. subsidiary that operates in a local currency environment, where that local currency is the functional currency, are translated into U.S. dollars at exchange rates in effect at the balance sheet date and the resulting translation adjustments directly recorded to a separate component of accumulated other comprehensive loss. Income and expense accounts are translated at average exchange rates during the year. Transactional gains and losses from foreign currency transactions are recorded in other (income) loss, net.

Segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision-making group, in deciding how to allocate resources and in assessing performance. The Company further evaluates its operating segments to determine its reportable segments. Aemetis recognizes three reportable segments “California Ethanol”, “Dairy Renewable Natural Gas”, and “India Biodiesel.”

The “California Ethanol” reportable segment includes the Company’s 65 million gallon per year ethanol plant in Keyes, California, and the adjacent land leased for the production of CO₂.

The “Dairy Renewable Natural Gas” reportable segment includes, the dairy digesters, pipeline and gas condition unit for the production of biogas from dairies near Keyes, California.

The “India Biodiesel” reportable segment includes the Company’s 50 million gallon per year nameplate capacity biodiesel manufacturing Kakinada Plant, the administrative offices in Hyderabad, India, and the holding companies in Nevada and Mauritius. The Company’s biodiesel is marketed and sold primarily to customers in India through brokers and by the Company directly.

The Company has additional operating segments that were determined not to be reportable segments, including the Carbon Zero 1 facility in Riverbank, the Goodland Plant, Kansas and the research and development facility in Minnesota. Refer to the “All Other” category.

Share-Based Compensation. The Company recognizes share based compensation expense in accordance with ASC 718 Stock Compensation requiring the Company to recognize expenses related to the estimated fair value of the Company’s share-based compensation awards at the time the awards are granted, adjusted to reflect only those shares that are expected to vest.

Commitments and Contingencies. The Company records and/or discloses commitments and contingencies in accordance with ASC 450 Contingencies. ASC 450 applies to an existing condition, situation, or set of circumstances involving uncertainty as to possible loss that will ultimately be resolved when one or more future events occur or fail to occur.

Convertible Instruments. The Company evaluates the impacts of convertible instruments based on the underlying conversion features. Convertible Instruments are evaluated for treatment as derivatives that could be bifurcated and recorded separately. Any beneficial conversion feature is recorded based on the intrinsic value difference at the commitment date.

Debt Issuance Costs. The Company records debt issuance costs related to specific incremental costs directly attributable to issuing, modifying, or extending a debt instrument. The debt issuance costs are reported as an adjustment to the carrying amount of the debt. The debt issuance costs are amortized using the interest rate method over the life of the debt instrument.

Troubled Debt Restructuring Accounting. The evaluation for troubled debt restructuring includes assessing whether the creditor granted a concession. To determine this, we calculate the post-restructuring effective interest rate by projecting cash flows on the new terms and calculating a discount rate equal to the carrying amount of pre-restructuring debt, and comparing this calculation to the terms of prior amendments. If the post restructuring effective interest rate is less than the prior terms effective interest rate, we assess this as having been granted a concession. We then apply troubled debt restructuring accounting to any debt in which the creditor granted a concession.

Debt Modification Accounting. The Company evaluates amendments to its debt in accordance with ASC 540-50 Debt – Modification and Extinguishments for modification and extinguishment accounting. This evaluation includes comparing the net present value of cash flows of the new debt to the old debt to determine if changes greater than 10 percent occurred. In instances where the net present value of future cash flows changed more than 10 percent, the Company applies extinguishment accounting and determines the fair value of its debt based on factors available to the Company.

Recently Adopted Accounting Pronouncements.

ASU 2016-13: Measurement of Credit Losses on Financial Instruments. This ASU requires the use of an expected loss model for certain types of financial instruments and requires consideration of a broader range of reasonable and supportable information to calculate credit loss estimates.

ASU 2019-12: Simplifying the Accounting for Income Taxes. In December 2019, FASB issued ASU 2019-12, Income Taxes ("Topic 740"): Simplifying the Accounting for Income Taxes. The ASU simplifies accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The ASU also improves consistent application of and simplifies generally accepted accounting principles ("GAAP") for other areas of Topic 740 by clarifying and amending existing guidance. The ASU is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted including adoption in any interim period for periods for which financial statements have not yet been issued. On January 1, 2021, we adopted this ASU on a prospective basis and the adoption of this standard did not have an impact on our consolidated financial statements.
