Organization and Business – The consolidated financial statements include, for all periods presented, the accounts of Pacific Ethanol, Inc., a Delaware corporation ("Pacific Ethanol"), and its direct and indirect subsidiaries (collectively, the "Company"), including its subsidiaries, Kinergy Marketing LLC, an Oregon limited liability company ("Kinergy"), Pacific Ag. Products, LLC, a California limited liability company ("PAP"), PE Op Co., a Delaware corporation ("PE Op Co.") and all nine of the Company's ethanol production facilities as of March 31, 2020. As discussed in Note 2, on April 15, 2020, the Company completed its sale of its ownership interests in Pacific Aurora, LLC ("Pacific Aurora"), thereby divesting two of the Company's ethanol production facilities.

The Company is a leading producer and marketer of low-carbon renewable fuels in the United States. The Company's four ethanol plants in California, Oregon and Idaho (together with their respective holding companies, the "Pacific Ethanol West Plants") are located in close proximity to both feed and ethanol customers and thus enjoy unique advantages in efficiency, logistics and product pricing. The Company's ethanol plants in Illinois and Nebraska (together with their respective holding companies, the "Pacific Ethanol Central Plants") are located in the heart of the Corn Belt, benefit from low-cost and abundant feedstock production and allow for access to many additional domestic markets. In addition, the Company's ability to load unit trains from these facilities in the Midwest allows for greater access to international markets. On April 15, 2020, the Company sold its interests in the Nebraska facilities.

Following the Company's sale of its interest in Pacific Aurora, the Company has a combined production capacity of 450 million gallons per year, markets, on an annualized basis, nearly 1.0 billion gallons of ethanol and specialty alcohols, based on historical volumes, and produces, on an annualized basis, nearly 3.0 million tons of co-products on a dry matter basis, such as wet and dry distillers grains, wet and dry corn gluten feed, condensed distillers solubles, corn gluten meal, corn germ, dried yeast and CO₂, based on historical volumes.

As of March 31, 2020, the Company was operating at approximately 40% of production capacity. 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.

Basis of Presentation–Interim Financial Statements – The accompanying unaudited consolidated financial statements and related notes have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Results for interim periods should not be considered indicative of results for a full year. These interim consolidated financial statements should be read in conjunction with the consolidated financial statements and related notes contained in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. The accounting policies used in preparing these consolidated financial statements are the same as those described in Note 1 to the consolidated financial statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair statement of the results for interim periods have been included. All significant intercompany accounts and transactions have been eliminated in consolidation.

Liquidity – The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As a result of ethanol industry conditions that have negatively affected the Company's business, the Company does not currently have sufficient liquidity to meet its anticipated working capital, debt service and other liquidity needs in the near-term. The Company has reduced production at its facilities by more than 60% subsequent to quarter-end in an effort to conserve capital in response to a substantial reduction in demand due to stay-at-home orders issued in response to the coronavirus pandemic. The Company has obtained additional liquidity from the completion of the sale of its interest in Pacific Aurora and through government loan programs. The Company has also taken and expects to take additional steps to preserve liquidity. However, despite these efforts, the Company does not believe that it has sufficient working capital to continue operations for the next twelve months, unless it successfully restructures its debt, sells additional assets, experiences a significant improvement in demand and margins for its products and/or obtains other sources of liquidity. In addition, if demand and margins do not promptly and sustainably improve, the Company may be forced to further curtail or cease production at its operating facilities. As a result of these factors, there exists substantial doubt as to the Company's ability to continue as a going concern.

The Company, as previously agreed with its lenders, has presented and continues to negotiate a comprehensive plan to restructure its assets and liabilities. The Company has appointed a chief restructuring officer to facilitate the development of such a plan and to assist in the Company's present strategic initiatives. The Company expects the negotiated plan will include additional assets sales, soliciting new investments in the Company or its assets, further debt payment deferrals and reductions, cutting overhead expenses and other cash preserving initiatives. The Company intends that the plan will provide the means to maintain sufficient liquidity for the next twelve months.

Accounts Receivable and Allowance for Doubtful Accounts – Trade accounts receivable are presented at face value, net of the allowance for doubtful accounts. The Company sells ethanol to gasoline refining and distribution companies, sells distillers grains and other feed co-products to dairy operators and animal feedlots and sells corn oil to poultry and biodiesel customers generally without requiring collateral.

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 the Company's customers were to deteriorate, resulting in an impairment of ability to make payments, additional allowances may be required.

Of the accounts receivable balance, approximately $41,237,000 and $63,736,000 at March 31, 2020 and December 31, 2019, respectively, were used as collateral under Kinergy's operating line of credit. The allowance for doubtful accounts was $58,000 and $39,000 as of March 31, 2020 and December 31, 2019, respectively. The Company recorded a bad debt expense of $19,000 and $26,000 for the three months ended March 31, 2020 and 2019, respectively. The Company does not have any off-balance sheet credit exposure related to its customers.

Financial Instruments – The carrying values of cash and cash equivalents, accounts receivable, derivative assets, accounts payable, accrued liabilities and derivative liabilities are reasonable estimates of their fair values because of the short maturity of these items. The carrying value of the Company's senior secured notes were recorded at fair value at December 31, 2019 and are considered Level 2 fair value measurements. The Company believes their carrying value approximates fair value at March 31, 2020. The Company believes the carrying value of its other long-term debt and assessment financing is not considered materially different than fair value because the interest rates on these instruments are variable, and are considered Level 2 fair value measurements.

Estimates and Assumptions – The preparation of the consolidated financial statements in conformity with 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 the reported amounts of revenues and expenses during the reporting period. Significant estimates are required as part of determining the allowance for doubtful accounts, net realizable value of inventory, estimated lives of property and equipment, long-lived asset impairments, valuation allowances on deferred income taxes and the potential outcome of future tax consequences of events recognized in the Company's financial statements or tax returns, and the valuation of assets acquired and liabilities assumed as a result of business combinations. Actual results and outcomes may materially differ from management's estimates and assumptions.
