Specifically, we buy corn as feedstock in producing ethanol from our working capital partner J.D. Heiskell and we sell all ethanol, WDG, CDO, and CDS produced to J.D. Heiskell. Our ethanol finished goods tank is leased to J.D. Heiskell and legal title to the product is transferred upon transfer of our finished ethanol to this location. We consider the purchase of corn as a cost of goods sold and consider the sale of ethanol as revenue upon transfer to the finished goods tank and consider the sale of WDG, CDO, and CDS as revenue, upon trucks leaving the Keyes Plant with the product, 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 ethanol, WDG, CDO, and CDS is set independently. Revenues from ethanol and WDG 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. We have 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.

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.

Substantial Doubt about Going Concern [Text Block]	13. The accompanying financial statements have been prepared contemplating the realization of assets and satisfaction of liabilities in the normal course of business. As a result of negative capital, negative market conditions resulting in prolonged idling of the Keyes Plant, negative operating results, and collateralization of substantially all of the company assets, the Company has been reliant on its senior secured lender to provide additional funding and has been required to remit substantially all excess cash from operations to the senior secured lender. In order to meet its obligations during the next twelve For the Keyes Plant, we restarted the plant during the second For Aemetis Biogas we plan to operate the biogas digesters to capture and monetize biogas as well as continue to build new dairy digesters and extend the existing pipeline in order to capture the carbon credits available in California. Funding for continued construction is based upon obtaining government guaranteed loans and executing on existing and new state grant programs. For the Kakinada Plant, we plan to continue to develop sales channels for domestic products as the costs of feedstock normalize against the price of diesel, as recently announced governmental incentives take effect to promote the blending of biodiesel, and as feedstocks such as refined animal tallow are used domestically and exported. Additionally, we are in the process of obtaining approval to export refined animal tallow and biodiesel produced using animal tallow into international markets as the use of refined animal tallow received approval from the Pollution Control Board of India for production of biodiesel. The repatriation of funds from India to the parent company in the U.S. is reliant on favorable governmental approvals. For the Riverbank project, we plan to continue project development and raise the funds necessary to construct and operate the Carbon Zero plant in Riverbank, California to produce renewable diesel and sustainable aviation fuel for transportation use as well as generate federal and state carbon credits available for the production and sale of low carbon fuels. For all facilities in the United States, we plan to utilize the provision of the Inflation Reduction Act of 2022 In addition to the above we plan to continue to locate funding for existing and new business opportunities through a combination of working with our senior lender, restructuring existing loan agreements, selling bonds in the taxable and tax-exempt markets, selling equity through the ATM and otherwise, selling the current EB- 5

Specifically, we buy corn as feedstock in producing ethanol from our working capital partner J.D. Heiskell and we sell all ethanol, WDG, CDO, and CDS produced to J.D. Heiskell. Our ethanol finished goods tank is leased to J.D. Heiskell and legal title to the product is transferred upon transfer of our finished ethanol to this location. We consider the purchase of corn as a cost of goods sold and consider the sale of ethanol as revenue upon transfer to the finished goods tank and consider the sale of WDG, CDO, and CDS as revenue, upon trucks leaving the Keyes Plant with the product, 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 ethanol, WDG, CDO, and CDS is set independently. Revenues from ethanol and WDG 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. We have 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.

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 when we enter into these situations. Hence, we are the principal in India sales scenarios where our customer and vendor may
