ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES | 1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES Organization and Business On December 15, 2016, the Company and Aurora Cooperative Elevator Company, a Nebraska cooperative corporation (“ACEC”), closed a transaction under a contribution agreement under which the Company contributed its Aurora, Nebraska ethanol production facilities and ACEC contributed its Aurora grain elevator and related grain handling assets to Pacific Aurora, LLC (“Pacific Aurora”) in exchange for equity interests in Pacific Aurora. As a result, the Company owned 73.93% of Pacific Aurora and ACEC owned 26.07% of Pacific Aurora. As discussed further in Note 2, the Company sold its interest in Pacific Aurora on April 15, 2020. Therefore, from December 15, 2016, through April 15, 2020, the Company consolidated 100% of the results of Pacific Aurora and recorded ACEC’s 26.07% equity interest as noncontrolling interests in the accompanying financial statements. The Company is a leading producer and marketer of specialty alcohols and essential ingredients. The Company also produces and markets fuel-grade ethanol. The Company’s production facilities in Pekin, Illinois are located in the heart of the Corn Belt, benefit from low-cost and abundant feedstock and allow for access to many additional domestic markets. In addition, the Company’s ability to load unit trains and barges from these facilities allows for greater access to international markets. The Company’s two production facilities in Oregon and Idaho are located in close proximity to both feed and fuel-grade ethanol customers and thus enjoy unique advantages in efficiency, logistics and product pricing. The Company has a combined alcohol production capacity of 350 million gallons per year and produces, on an annualized basis, nearly 1.2 million tons of essential ingredients on a dry matter basis, such as dried yeast, corn gluten meal, corn gluten feed, and distillers grains and liquid feed used in commercial animal feed and pet foods. In addition, the Company sells alcohols acquired from other producers and markets fuel-grade ethanol produced by third parties. The Company focuses on four key markets: Health, Home & Beauty Food & Beverage Essential Ingredients Renewable Fuels As of December 31, 2021, all of the Company’s production facilities were operating. As market conditions change, the Company may increase, decrease or idle production at one or more operating facilities or resume operations at any idled facility. On January 14, 2022, the Company acquired Eagle Alcohol Company LLC, a Missouri limited liability company (“Eagle Alcohol”). Eagle Alcohol specializes in break bulk distribution of specialty alcohols. Eagle Alcohol purchases bulk alcohol from suppliers, including the Company. Then it stores, denatures, packages, and resells alcohol products in smaller sizes, including tank trucks, totes, and drums, that garner a premium to bulk alcohols. Eagle Alcohol delivers products to customers in the beverage, food, pharma, and related-process industries via its own dedicated trucking fleet and common carrier. Eagle Alcohol generated over $35 million in revenues in 2021. Eagle Alcohol is now a wholly-owned subsidiary of the Company. See Note 16 for more details. Basis of Presentation Segments Segment Reporting Cash and Cash Equivalents Restricted Cash Accounts Receivable and 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 receivable are charged against the allowance for doubtful accounts once uncollectibility 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 a Company customer deteriorates, resulting in an impairment of ability to make payments, additional allowances may be required. Of the accounts receivable balance, approximately $63,929,000 and $35,839,000 at December 31, 2021 and 2020, respectively, were used as collateral under Kinergy’s operating line of credit. The allowance for doubtful accounts was $378,000 and $260,000 as of December 31, 2021 and 2020, respectively. The Company recorded a bad debt expense of $158,000, $245,000 and $27,000 for the years ended December 31, 2021, 2020 and 2019, respectively. The Company does not have any off-balance sheet credit exposure related to its customers. Concentration Risks The Company sells specialty alcohols to consumer product companies and fuel-grade ethanol to gasoline refining and distribution companies. The Company sold to customers representing 10% or more of the Company’s total net sales, as follows. Years Ended December 31, 2021 2020 2019 Customer A 13 % 3 % 9 % Customer B 9 % 9 % 11 % Customer C 1 % 5 % 13 % The Company had accounts receivable due from these customers totaling $14,336,000 and $5,756,000, representing 16% and 13% of total accounts receivable, as of December 31, 2021 and 2020, respectively. The Company purchases corn, its largest cost component in producing alcohols, from its suppliers. The Company purchased corn from suppliers representing 10% or more of the Company’s total corn purchases, as follows: Years Ended December 31, 2021 2020 2019 Supplier A 14 % 16 % 16 % Supplier B — % 9 % 25 % As of December 31, 2021, approximately 47% of the Company’s employees were covered by a collective bargaining agreement. Inventories December 31, 2021 2020 Finished goods $ 35,509 $ 25,154 Work in progress 6,909 4,333 Raw materials 10,837 7,074 Other 1,118 1,364 Total $ 54,373 $ 37,925 Property and Equipment Buildings 40 years Facilities and plant equipment 10 – 25 years Other equipment, vehicles and furniture 5 – 10 years The cost of normal maintenance and repairs is charged to operations as incurred. Significant capital expenditures that increase the life of an asset are capitalized and depreciated over the estimated remaining useful life of the asset. The cost of property and equipment sold, or otherwise disposed of, and the related accumulated depreciation or amortization are removed from the accounts, and any resulting gains or losses are reflected in current operations. Intangible Asset Leases Derivative Instruments and Hedging Activities Revenue Recognition The Company recognizes revenue primarily from sales of alcohols and essential ingredients. The Company has five production facilities from which it produces and sells alcohols to its customers through Kinergy. Kinergy enters into back-to-back sales contracts with its customers under exclusive intercompany sales agreements with each of the Company’s five production facilities. Kinergy also acts as a principal when it purchases third party fuel-grade ethanol which it resells to its customers. Finally, Kinergy has exclusive sales agreements with other third-party owned fuel-grade ethanol production facilities under which it sells their fuel-grade ethanol for a fee plus the costs to deliver the ethanol to Kinergy’s customers. These sales are referred to as third-party agent sales. Revenue from these third-party agent sales is recorded on a net basis, with Kinergy recognizing its predetermined fees and any associated delivery costs. The Company has five production facilities from which it produces and sells essential ingredients to its customers through Alto Nutrients. Alto Nutrients enters into sales contracts with essential ingredient customers under exclusive intercompany sales agreements with each of the Company’s five production facilities. The Company recognizes revenue from sales of alcohols and essential ingredients at the point in time when the customer obtains control of the products, which typically occurs upon delivery depending on the terms of the underlying contracts. In some instances, the Company enters into contracts with customers that contain multiple performance obligations to deliver volumes of alcohols or essential ingredients over a contractual period of less than 12 months. The Company allocates the transaction price to each performance obligation identified in the contract based on relative standalone selling prices and recognizes the related revenue as control of each individual product is transferred to the customer in satisfaction of the corresponding performance obligations. When the Company is the agent, the supplier controls the products before they are transferred to the customer because the supplier is primarily responsible for fulfilling the promise to provide the product, has inventory risk before the product has been transferred to a customer and has discretion in establishing the price for the product. When the Company is the principal, the Company controls the products before they are transferred to the customer because the Company is primarily responsible for fulfilling the promise to provide the products, has inventory risk before the product has been transferred to a customer and has discretion in establishing the price for the product. See Note 4 Shipping and Handling Costs Selling Costs Stock-Based Compensation Impairment of Long-Lived Assets Deferred Financing Costs Provision for Income Taxes The Company accounts for uncertainty in income taxes using a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining whether it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount which is more than 50% likely of being realized upon ultimate settlement. An uncertain tax position is considered effectively settled on completion of an examination by a taxing authority if certain other conditions are satisfied. Should the Company incur interest and penalties relating to tax uncertainties, such amounts would be classified as a component of interest expense and other income (expense), net, respectively. Deferred tax assets and liabilities are classified as noncurrent in the Company’s consolidated balance sheets. The Company files a consolidated federal income tax return. This return includes all wholly owned subsidiaries as well as the Company’s pro-rata share of taxable income from pass-through entities in which the Company owns less than 100%. State tax returns are filed on a consolidated, combined or separate basis depending on the applicable laws relating to the Company and its subsidiaries.
