Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Nature of the Business	BASIS OF PRESENTATION AND NATURE OF THE BUSINESS The condensed consolidated financial statements have been prepared by Renewable Energy Group, Inc. and its subsidiaries (the "Company" or "REG"), pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted as permitted by such rules and regulations. All adjustments, consisting of normal recurring adjustments, have been included. Management believes that the disclosures are adequate to present fairly the financial position, results of operations and cash flows at the dates and for the periods presented. It is suggested that these interim financial statements be read in conjunction with the consolidated financial statements and the notes thereto appearing in the Company’s latest annual report on Form 10-K filed on March 1, 2022. Results for interim periods are not necessarily indicative of those to be expected for the fiscal year. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts and related disclosures. Actual results could differ from those estimates. The Company currently owns and operates a network of eleven bio-based diesel production facilities, with nine locations in North America and two locations in Europe, and an aggregate nameplate production capacity of 470 million gallons per year ("mmgy"). Ten of these plants are “multi-feedstock capable”, which allows them to use a broad range of low carbon feedstocks, such as distillers corn oil, used cooking oil and inedible animal fats in addition to vegetable oils, such as soybean oil, and canola oil. The bio-based diesel industry and the Company’s business have benefited from certain federal and state government programs. The federal biodiesel mixture excise tax credit (the "BTC") was retroactively reinstated on December 20, 2019 for the years 2018 and 2019. The BTC has also been extended through December 31, 2022. The modification of federal and state government programs could adversely affect the financial results of the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES The following accounting policies should be read in conjunction with a summary of the significant accounting policies the Company has disclosed in its Annual Report on Form 10-K for the year ended December 31, 2021. Accounting for Business Combinations The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets, and assumed liabilities at their acquisition date fair values. The excess of the purchase price over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, royalty rates and asset lives, among other items. Restricted Cash The Company segregates certain cash balances as restricted cash that represent those funds required to be set aside by a contractual agreement. The Company classifies restricted cash between current and non-current assets based on the length of time of the restricted use. As of March 31, 2022 and 2021, current restricted cash was $3,000 and $3,746 for each period, representing pledges for outstanding letters of credit issued to support our operations. See the table below for reconciliation of "Cash, Cash Equivalents and Restricted Cash" in the Condensed Consolidated Statements of Cash Flows: March 31, 2022 March 31, 2021 Cash and cash equivalents $ 340,703 $ 335,789 Restricted cash 3,000 3,746 Total cash, cash equivalents and restricted cash in the Condensed Statements of Cash Flows $ 343,703 $ 339,535 Marketable Securities The Company's marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income (loss). The Company classifies its marketable securities as either current or long-term based on each instrument's underlying contractual maturity date. Realized gains or losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are reported in other income, net. The Company evaluates such investments periodically for possible other-than-temporary impairment. A decline of fair value below amortized costs of debt securities is considered an other-than-temporary impairment if the Company has the intent to sell the security or if it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis. In those instances, an impairment charge equal to the difference between the fair value and the amortized cost basis is recognized in earnings. Regardless of the Company's intent or requirement to sell a debt security, an impairment is considered other-than-temporary if the Company does not expect to recover the entire amortized cost basis; in those instances, a credit loss equal to the difference between the present value of the cash flows expected to be allocated based on credit risk and the amortized cost basis of the debt security is recognized in earnings. The Company has no current requirement or intent to sell a material portion of marketable securities as of March 31, 2022. The Company expects to recover up to (or beyond) the initial cost of investment for securities held. In computing realized gains and losses on available-for-sale securities, the Company determines cost based on amounts paid, including direct costs such as commissions to acquire the security, using the specific identification method. Renewable Identification Numbers ("RINs") When the Company produces and sells a gallon of bio-based diesel for use in the United States, 1.5 to 1.7 RINs per gallon are generated. RINs are used to track compliance with the Renewable Fuel Standard, using the EPA moderated transaction system. RFS2 allows the Company to attach between zero and 2.5 RINs to any gallon of bio-based diesel. As a result, a portion of the selling price for a gallon of bio-based diesel sold in the U.S. is generally attributable to RFS2 compliance. However, RINs that the Company generates are a form of government incentive and not a result of the physical attributes of the bio-based diesel production. Therefore, no cost is allocated to the RIN when it is generated, regardless of whether the RIN is transferred with the bio-based diesel produced or held by the Company pending attachment to other bio-based diesel production sales. Additionally, RINs, once obtained through the production and sale of gallons of bio-based diesel, may be separated by the acquirer and sold separately. In addition, the Company also obtains RINs from third parties who have separated the RINs from gallons of bio-based diesel. From time to time, the Company holds varying amounts of these separated RINs for resale. RINs obtained from third parties are initially recorded at their cost and are subsequently revalued at the lower of cost or net realizable value as of the last day of each accounting period. The resulting adjustments are reflected in costs of goods sold for the period. The value of these RINs is reflected in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets. The cost of goods sold related to the sale of these RINs is determined using the average cost method, while market prices are determined by RIN values, as reported by the Oil Price Information Service ("OPIS"). Low Carbon Fuel Standard The Company generates LCFS credits for its low carbon fuels when its qualified low carbon fuels are transported into an LCFS market and sold for qualifying purposes. LCFS credits are used to track compliance with the LCFS. As a result, a portion of the selling price for a gallon of bio-based diesel sold into an LCFS market is also attributable to LCFS compliance. However, LCFS credits that the Company generates are a form of government incentive and not a result of the physical attributes of the bio-based diesel production. Therefore, no cost is allocated to the LCFS credit when it is generated, regardless of whether the LCFS credit is transferred with the bio-based diesel produced or held by the Company. In addition, the Company also obtains LCFS credits from third-party trading activities. From time to time, the Company holds varying amounts of these third-party LCFS credits for resale. LCFS credits obtained from third parties are initially recorded at their cost and are subsequently revalued at the lower of cost or net realizable value as of the last day of each accounting period, and the resulting adjustments are reflected in costs of goods sold for the period. The value of LCFS credits obtained from third parties is reflected in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheet. The cost of goods sold related to the sale of these LCFS credits is determined using the average cost method, while market prices are determined by LCFS values, as reported by the OPIS. The Company records assets acquired and liabilities assumed through the exchange of non-monetary assets based on the fair value of the assets and liabilities acquired or the fair value of the consideration exchanged, whichever is more readily determinable. Impairment of Long-lived Assets The Company tests its long-lived assets for recoverability when events or circumstances indicate that its carrying amount may not be recoverable. Significant assumptions used in the undiscounted cash flow analysis, when it is required, include the projected demand for biomass-based diesel based on annual renewable fuel volume obligations under the Renewable Fuel Standards ("RFS2"), the Company's capacity to meet that demand, the market price of biomass-based diesel and the cost of feedstock used in the manufacturing process. During the three months ended March 31, 2022, the Company recorded impairment charges of $2,748 related to certain property, plant and equipment due to the change in the intent to utilize these assets and that the carrying amounts of these assets deemed not recoverable given the assets' deteriorating physical conditions identified during the period. During the first quarter of 2021, the Company recorded impairment charges of $822 related to certain equipment as the carrying amounts of these assets were deemed not recoverable given the assets' deteriorating physical conditions identified during the period. Green Notes On May 20, 2021, the Company completed the sale and issuance of $550,000 aggregate principal amount of 5.875% senior secured notes due in 2028 (the "Green Notes"). The Company recorded $14,619 in legal, professional and underwriting fees related to the issuance of the Green Notes. The Company currently intends to use the net proceeds from this offering for capital expenditures related to the improvement and expansion of its Geismar, Louisiana biorefinery. See "Note 8—Debt" for a further description of the Green Notes. Security Repurchase Program In February 2020, the Company's Board of Directors approved a repurchase program of up to $100,000 of the Company's shares of common stock and/or its previously outstanding convertible notes (the "2020 Program"). Under this program, the Company may repurchase shares from time to time in open market transactions, privately negotiated transactions or by other means. The timing and amount of repurchase transactions under the program are determined by the Company's management based on its evaluation of market conditions, share price, legal requirements and other factors. There were no repurchases under the 2020 Program in the three months ended March 31, 2022, and the remaining amount of the 2020 Program was $91,914 as of March 31, 2022. Equity Offering On March 19, 2021, the Company completed an equity offering pursuant to which it sold 5,750,000 shares of common stock to various underwriters at a price of $67.00 per share before underwriting discounts and commissions. The proceeds that the Company received from the financing activity were $385,250 before underwriting discounts and commissions, fees, and other out-of-pocket costs of $19,970. The net proceeds from the transaction were $365,280. Revenue Recognition The Company generally has a single performance obligation in its arrangements with customers. The Company believes for most of its contracts with customers, control is transferred at a point in time, typically upon delivery to the customers. When the Company performs shipping and handling activities after the transfer of control to the customers (e.g., when control transfers prior to delivery), they are considered as fulfillment activities, and accordingly, the costs are accrued for when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. The Company generally expenses sales commissions when incurred because the amortization period would have been less than one year. The Company records these costs within selling, general and administrative expenses. The following is a description of principal activities from which we generate revenue. Revenues from contracts with customers are recognized when control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. • sales of biodiesel and RD produced at our facilities, including RINs and LCFS credits; • resale of biodiesel, RD and petroleum and petroleum-based products acquired from third parties, along with the sale of RD and petroleum-based products further blended with biodiesel produced at our wholly owned facilities or acquired from third parties; • sales of separated RINs and LCFS credits; • sales of raw materials, glycerin and other co-products of the bio-based diesel production process; • other revenue, including bio-based diesel facility management and operational services; and • incentive payments from federal and state governments, including the BTC, and from the USDA Advanced Biofuel Program.

Contract liabilities include payments received in advance of performance under the contract, and are realized with the associated revenue recognized under the contract. Significant changes to the contract liabilities during the three months ended March 31, 2022 and 2021 are as follows: January 1, 2022 Cash receipts Less: Impact on March 31, 2022 Deferred revenue $ 1,822 $ 75,475 $ 64,561 $ 12,736 Payables to customers related to BTC 699 — — 699 $ 2,521 $ 75,475 $ 64,561 $ 13,435 January 1, 2021 Cash receipts Less: Impact on March 31, 2021 Deferred revenue $ 946 $ 12,963 $ 13,306 $ 603 Payables to customers related to BTC 914 — 215 699 $ 1,860 $ 12,963 $ 13,521 $ 1,302 New Accounting Standards On March 12, 2020, the FASB issued ASU 2020-04, which provides a relief that is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Optional expedients are provided for contract modification accounting under the following Codification topics and subtopics: ASC 310, Receivables; ASC 470, Debt; ASC 840 or ASC 842, Leases; and ASC 815-15, Derivatives and Hedging: Embedded Derivatives. The ASU also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. T he amendments in ASU 2020-04 are effective for all entities as of March 12, 2020, through December 31, 2022. The Company has determined that the impact of the guidance on its condensed consolidated financial statements is not material. On August 5, 2020, the FASB issued ASU 2020-06, which reduces the complexity of the accounting for convertible debt instruments and its effect on earnings per share calculation. The guidance reduces the number of accounting models used for convertible debt instruments, which will result in fewer embedded conversion features being recognized separately from the original contract. This will also affect the guidance associated with convertible debt for earnings-per-share by requiring the if-converted method rather than the treasury stock method, requiring that potential share settlement be included in the calculation of diluted earnings per share and clarifying that an entity should use the weighted-average share count from each quarter when calculating the year-to-date weighted-average share count. For public business entities, the amendments in ASU 2020-06 are effective for fiscal years beginning after December 15, 2021, including interim periods within those years, and early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those years. The Company has determined that the guidance has no material impact on its condensed consolidated financial statements. On October 28, 2021, the FASB issued ASU 2021-08, which updates the guidance related to the acquisition of revenue contracts in a business combination. The new guidance requires that the acquiring entity recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date the acquirer should recognize the contract assets and liabilities under Topic 606 as they would have been recognized at contract origination rather than at fair value at the time of the acquisition. The intent is to create more comparability of recognition and measurement of the acquired contracts in business combinations. For public business entities, the amendments in ASU 2021-08 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is evaluating the impact of the guidance on its condensed consolidated finance statements. On November 17, 2021, the FASB issued ASU 2021-10, which requires business entities to provide certain disclosures when they (1) have received government assistance and (2) use a grant or contribution accounting model by analogy to other accounting guidance. The guidance will require business entities to disclose the nature of the transactions, accounting policies used to account for the transactions, and state which line items on the balance sheet and income statement are affected by these transactions and the amount applicable to each financial statement line. Business entities will also have to disclose significant terms and conditions of transactions with a government such as the duration of the agreement, any commitments made by either side, provisions, and contingencies. The guidance in ASU 2021-10 is effective for all entities for fiscal years beginning after December 15, 2021. Entities may apply the provision either (1) prospectively to all transactions within the scope of ASC 832 that are reflected in the financial statements as of the adoption date and all new transactions entered into after the date of adoption or (2) retrospectively. Early adoption is permitted. The Company has determined that the impact of the guidance on its condensed consolidated financial statements is not material. On March 28, 2022, the FASB issued ASU 2022-01, which updates the guidance related to the optional hedge accounting model. The guidance better portrays the economic results of an entity's risk management activities in its financial statements by expanding the scope of ASU 2017-12. The expansion allows for multiple hedged layers to be designated for a single closed portfolio of financial instruments or one or more beneficial interests secured by a portfolio of financial instruments, which is referred to as a portfolio layer method hedge. As a result, an entity can achieve hedge accounting for hedges of a greater proportion of the interest rate risk inherent in the assets included in the closed portfolio. The guidance for ASU 2022-10 is effective for public business entities December 15, 2022. Upon adoption, The Company must decide within 30 days which securities already in closed portfolios will be designated in a portfolio layer method hedge. The Company is evaluating the impact of guidance on its condensed consolidated financial statements.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	ACQUISITIONS On December 30, 2021, the Company acquired 100% of the stock of Amber Resources. Amber Resources is one of the leading full-service petroleum distributors and providers in Southern California, offering a broad product line of fuel, lubricants and diesel exhaust fluid ("DEF") solutions via highly differentiated, service-oriented model. Amber Resources is consolidated into REG in accordance with ASC 805, Business Combinations and is part of the Bio-based Diesel Reportable Segment. The Company completed its preliminary accounting of this business combination as the valuation of the acquired assets and assumed liabilities, including a tax reserve, was not finalized as of the date of this report. The consideration for the acquisition of Amber Resources, after adjusting for net working capital items allowed under the purchase agreement, was $78,434. The Company used the income approach to value certain intangible assets. Under the income approach, an intangible asset’s fair value is equal to the present value of future economic benefits to be derived from ownership of the asset. The Company used the income approach known as the relief from royalty method to value the fair value of the trade names. The relief from royalty method is based on the hypothetical royalty stream that would be received if we were to license the trade name and was based on expected revenues. The determination of the fair value of other assets acquired and liabilities assumed involves assessing factors such as the expected future cash flows associated with individual assets and liabilities and appropriate discount rates at the date of the acquisition. The following table summarizes the fair values of the assets acquired and liabilities assumed at the acquisition date. December 30, 2021 Assets (liabilities) acquired of Amber Resources: Cash $ 5,643 Accounts receivable (net of allowance for doubtful accounts) 15,502 Inventory 8,830 Other current assets 4,558 Property, plant and equipment 16,248 Right of use assets 15,773 Intangibles 45,000 Goodwill 23,986 Other assets 4,023 Total assets acquired 139,563 Accounts payable 20,467 Accrued expenses and other liabilities 9,495 Current maturities of operating lease obligations 1,528 Other liabilities 2,625 Deferred income taxes 12,600 Long-term operating lease obligations 14,414 Total liabilities acquired $ 61,129

The Green Notes bear interest at a rate of 5.875% per annum, payable semi-annually in arrears on June 1 and December 1, beginning on December 1, 2021. The Green Notes will mature on June 1, 2028, unless earlier repurchased or redeemed. The Company currently intends to use the net proceeds from this offering for capital expenditures related to the improvement and expansion of its Geismar, Louisiana RD biorefinery. The Company recorded $14,619 in legal, professional and underwriting fees related to the issuance of the Green Notes. These financing costs are being amortized using the effective interest method over the term of the debt. Prior to June 1, 2024, the Company may, at its option but subject to the conditions in the Indenture, (i) redeem up to 35% of the aggregate principal amount of the Green Notes at a redemption price equal to 105.875% of the aggregate principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the redemption date, with the net cash proceeds received by the Company in one or more equity offerings; provided that at least 65% of the aggregate principal amount of the Green Notes issued under the Indenture (including any additional notes originally issued under the Indenture) remain outstanding after each such redemption or (ii) redeem all or part of the Green Notes at a price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but not including, the applicable redemption date of the notes redeemed by us and a “make-whole” premium.

Generally, if an event of default occurs and is continuing, the trustee or holders of at least 25% in principal amount of the then outstanding Green Notes may declare the principal of, premium, and accrued but unpaid interest on all the Green Notes to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately.

Fair Value Disclosures [Abstract]
Fair Value Measurement	FAIR VALUE MEASUREMENT The fair value hierarchy prioritizes the inputs used in measuring fair value as follows: • Level 1 — Quoted prices for identical instruments in active markets. • Level 2 — Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-derived valuations, in which all significant inputs are observable in active markets. • Level 3 — Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. A summary of assets (liabilities) measured at fair value is as follows: As of March 31, 2022 Total Level 1 Level 2 Level 3 Commercial paper $ 109,019 $ — $ 109,019 $ — Corporate bonds $ 325,884 — 325,884 — Municipal bonds $ 11,800 — 11,800 — Commodity contract derivatives $ (13,294) (2,315) (10,979) — $ 433,409 $ (2,315) $ 435,724 $ — As of December 31, 2021 Total Level 1 Level 2 Level 3 Commercial paper $ 116,902 $ — $ 116,902 $ — Corporate bonds $ 329,777 — 329,777 — Municipal bonds $ 11,906 — 11,906 — Commodity contract derivatives $ (1,459) (366) (1,093) $ — $ 457,126 $ (366) $ 457,492 $ — The estimated fair values of the Company’s financial instruments, which are not recorded at fair value, are as follows: As of March 31, 2022 As of December 31, 2021 Asset (Liability) Fair Value Asset (Liability) Fair Value Financial liabilities: Debt and line of credit $ (550,000) $ (567,976) $ (550,000) $ (552,877) The carrying amounts reported in the Condensed Consolidated Balance Sheets for cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate their fair values. Money market funds are included in cash and cash equivalents on the Condensed Consolidated Balance Sheets. The Company used the following methods and assumptions to estimate fair value of its financial instruments: Marketable securities: The fair value of marketable securities, which include Treasury bills and municipal notes/bonds, commercial paper and corporate notes/bonds is obtained using quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets in markets that are not active and inputs other than quoted prices, e.g., interest rates and yield curves. Commodity derivatives: The instruments held by the Company consist primarily of futures contracts, swap agreements, purchased put options and written call options. The fair value of contracts based on quoted prices of identical assets in an active exchange-traded market is reflected in Level 1. Contract fair value that is determined based on quoted prices of similar contracts in over-the-counter markets is reflected in Level 2. Debt and line of credit: The fair value of long-term debt and line of credit was established using discounted cash flow calculations and current market rates reflecting Level 2 inputs.

Earnings Per Share [Abstract]
Net Income Per Share	NET INCOME PER SHARE Basic net income per share is presented in conformity with the two-class method required for participating securities, which include restricted stock units ("RSUs"). Under the two-class method, net income is reduced for distributed and undistributed dividends earned in the current period. The remaining earnings are then allocated to Common Stock and the participating securities. The Company calculates the effects of participating securities on diluted earnings per share ("EPS") using both the “if-converted or treasury stock” and "two-class" methods and discloses the method which results in a more dilutive effect. The effects of stock appreciation rights on diluted EPS are calculated using the treasury stock method unless the effects are anti-dilutive to EPS. The following table presents the calculation of diluted net income per share available to common stockholders: Three months ended March 31, 2022 Three months ended March 31, 2021 Net income available to the Company's common stockholders - Basic $ 12,392 $ 38,583 Plus (less): effect of participating securities 85 639 Net income available to common stockholders 12,477 39,222 Less: effect of participating securities (85) (639) Net income available to the Company's common stockholders - Diluted $ 12,392 $ 38,583 Shares: Weighted-average shares used to compute basic net income per share 50,338,496 40,425,593 Adjustment to reflect conversion of convertible notes — 2,640,938 Adjustment to reflect stock appreciation right conversions 220,402 595,037 Weighted-average shares used to compute diluted net income per share 50,558,898 43,661,568 Net income per share available to common stockholders - Diluted Diluted net income $ 0.25 $ 0.88

Segment Reporting [Abstract]
Reportable Segments and Geographic Information	REPORTABLE SEGMENTS AND GEOGRAPHIC INFORMATION The Company reports its reportable segments based on products and services provided to customers. The Company re-assesses its reportable segments on an annual basis. The Company's reportable segments generally align the Company's external financial reporting segments with its internal operating segments, which are based on its internal organizational structure, operating decisions, and performance assessment. The Company's reportable segments at March 31, 2022 and for the year ended December 31, 2021 are composed of Bio-based Diesel (formerly known as the Biomass-based Diesel segment), Services and Corporate and other activities. The accounting policies of the segments are the same as those described in the summary of significant accounting policies. The Bio-based Diesel segment processes waste vegetable oils, animal fats, virgin vegetable oils and other feedstocks into bio-based diesel. The Bio-based Diesel segment also includes the Company’s purchases and resales of bio-based diesel produced by third parties. Revenue is derived from the purchases and sales of bio-based diesel, the renewable portion of sales of biodiesel and RD blended with petroleum-based diesel, resale of biodiesel, RD and petroleum and petroleum-based products acquired from third parties, along with the sale of RD and petroleum-based products further blended with biodiesel produced at the Company's wholly owned facilities or acquired from third parties, RINs and raw material feedstocks acquired from third parties, sales of processed bio-based diesel from Company facilities, related byproducts and renewable energy government incentive payments, in the U.S. and internationally. The Services segment offers services for managing the construction of bio-based diesel production facilities and managing ongoing operations of third-party plants and collects fees related to the services provided. The Company does not allocate items that are of a non-operating nature or corporate expenses to the business segments. Revenues from services provided to other segments are recorded by the Services segment at cost. The Corporate and Other segment includes trading activities related to petroleum-based heating oil and diesel fuel, including the petroleum portion of sales of biodiesel and RD blended with petroleum-based diesel and petroleum-based products acquired from third parties; as well as corporate activities, which consist of corporate office expenses such as compensation, benefits, occupancy, and other administrative costs, including management service expenses. Corporate and Other also includes income/(expense) not associated with the reportable segments, such as corporate general and administrative expenses, shared service expenses, interest expense and interest income, all reflected on an accrual basis of accounting. In addition, Corporate and Other includes cash and other assets not associated with the reportable segments, including investments. Intersegment revenues are reported by the Services and Corporate and Other segments. The following table represents the significant items by reportable segment: Three months ended March 31, 2022 Three months ended March 31, 2021 Net sales: Bio-based Diesel $ 848,190 $ 500,262 Services 68,252 17,352 Corporate and Other 88,904 40,509 Intersegment revenues (69,357) (18,379) $ 935,989 $ 539,744 Income (loss) before income taxes: Bio-based Diesel $ 33,572 $ 48,251 Services 777 (3,998) Corporate and Other (21,451) (3,398) $ 12,898 $ 40,855 Depreciation and amortization expense, net: Bio-based Diesel $ 15,304 $ 13,904 Services 972 888 Corporate and Other 1,011 824 $ 17,287 $ 15,616 Cash paid for purchases of property, plant and equipment: Bio-based Diesel $ 57,623 $ 9,814 Services 894 348 Corporate and Other 17 325 $ 58,534 $ 10,487 March 31, 2022 December 31, 2021 Goodwill: Bio-based Diesel $ 23,986 $ 27,784 Services 16,080 16,080 $ 40,066 $ 43,864 Assets: Bio-based Diesel $ 1,736,104 $ 1,668,801 Services 126,640 122,843 Corporate and Other 1,238,798 1,315,674 Intersegment eliminations (473,496) (548,374) $ 2,628,046 $ 2,558,944 Geographic Information: The following geographic data include net sales attributed to the countries based on the location of the subsidiary making the sale and long-lived assets based on physical location.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES Commitments In October 2020, the Company announced that it planned to expand the effective capacity of its Geismar, Louisiana biorefinery. The Geismar project brings together the planned improvement and expansion project for the existing site. The Geismar project is expected to take total site production capacity from 90 mmgy to 340 mmgy, enhance existing operations and improve operational reliability and logistics. The expansion is expected to be mechanically complete in 2023 with full operations in early 2024. The capital cost for the Geismar project is estimated to be $950,000. In connection with its announced improvement and expansion of our Geismar, Louisiana biorefinery facility, the Company has entered into construction, marine terminal lease, which is expected to commence in August 2023, and other long-lead time contracts for the project. Currently the estimated total future commitments under these contracts amount to approximately $567,867. The following table outlines the minimum contract commitments related to the executed contracts noted above. Construction Commitments Minimum Lease Commitments Total Commitments April 1 - December 31, 2022 $ 168,629 $ — $ 168,629 2023 72,026 9,083 81,109 2024 216 21,800 22,016 2025 — 21,800 21,800 2026 — 21,800 21,800 2027 — 21,800 21,800 2028 and thereafter — 230,713 230,713 Total $ 240,871 $ 326,996 $ 567,867 Contingencies In the last quarter of 2020, the Company discovered a blending discrepancy in connection with its preparation for a standard IRS audit of its BTC filings. The Company self-reported the findings to the IRS and initiated an investigation overseen by the Audit Committee of the Company’s Board of Directors. In March 2021, the Company paid to the IRS the $40,505 assessment, excluding interest which was paid in April 2021, to correct the REG Seneca BTC claims (hereafter "BTC Correction"). The Company is working with its customers on BTC re-filings on the relevant gallons to reduce further the BTC Correction, which may include recovering amounts from its customers. There can be no assurances that future reduction to the BTC Correction will occur. On March 2, 2021, a putative class action lawsuit was filed against the Company and certain of its current and former executive officers in the United Stated District Court for the Southern District of New York. On March 12, 2021, a putative class action lawsuit against the same defendants was filed in the United States District Court for the Central District of California. On June 24, 2021, the two cases were consolidated in the Southern District of New York under the caption In re Renewable Energy Group Securities Litigation, No. 21-cv-1832 , and a consolidated amended complaint was filed on July 9, 2021. The complaint purports to be brought on behalf of shareholders who purchased the Company’s common stock between March 8, 2018 and February 25, 2021, the date on which the Company announced its restatement related to BTC. Plaintiffs allege that defendants made false and misleading statements about the Company’s business, financial results and prospects in violation of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Rule 10b-5 promulgated thereunder. The complaint seeks unspecified damages, attorneys’ fees, and other costs. On January 20, 2022, the court granted defendants' motion to dismiss with prejudice and entered a judgment dismissing the case. On February 18, 2022, plaintiff filed a notice of appeal of the order granting the motion to dismiss and the entry of judgement. The Company denies any and all allegations of wrongdoing and intends to vigorously defend against the litigation. On July 27, 2021, a stockholder derivative complaint was filed in the United States District Court for the District of Delaware based on allegations substantially similar to those in the class action, and purporting to asset claims on the Company's behalf against current and former officers and directors for alleged violation of Sections 14(a) and 20(a) of the Exchange Act, breach of fiduciary duties, unjust enrichment, and waste of corporate assets. On August 2, 2021, a second stockholder derivative complaint purportedly arising out of the same events and purporting to assert similar claims, was filed in the Supreme Court for the State of New York. Both of these derivative actions have been stayed. In addition, the SEC requested information about the restatement, and the Company cooperated with the SEC. On October 1, 2021, the SEC Staff notified the Company that the Staff terminated its investigation with no enforcement action recommended against the Company, in accordance with SEC guidelines. Additionally, following the announcement of the Merger (see Note 14 - Proposed Plan of Merger), ten purported stockholders of REG filed complaints against REG and each member of the Board alleging violations of the federal securities laws. Such complaints allege that REG’s Schedule 14A filed on March 23, 2022 — and in the case of three complaints, the Definitive Proxy Statement — omits material information with respect to the Merger and that, as a result, all defendants violated Section 14(a) of the Exchange Act and that each Board member violated Section 20(a) of the Exchange Act. Certain of the complaints additionally allege that all defendants violated Rule 14a-9 promulgated under the Exchange Act. Certain of the complaints additionally allege that each Board member violated 17 C.F.R. § 244.100. Each complaint seeks (i) injunctive relief; (ii) rescission in the event the Merger is consummated or alternatively rescissory damages; (iii) plaintiff’s attorneys’ and experts’ fees and costs; and (iv) other such relief that the court deems just and proper. Certain of the complaints additionally seek a direction that the Board issue a revised Schedule 14A and a declaration that the defendants violated Sections 14(a) and/or 20(a) of the Exchange Act, as well as Rule 14a-9 promulgated thereunder. REG believes the claims asserted in the complaints are without merit. Additional lawsuits may be filed against REG, the Board, or REG’s officers in connection with the Merger, which could prevent or delay completion of the Merger and result in substantial costs to REG, including any costs associated with indemnification. For a more complete summary of the litigation relating to the Merger, see “The Merger Agreement—Litigation Relating to the Merger” beginning on page 90 of the 2022 Proxy filing. The Company is also involved in various other legal proceedings in the normal course of business. The Company currently believes that any ultimate liability arising out of such proceedings will not have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Business Combination and Asset Acquisition [Abstract]
Proposed Plan of Merger	PROPOSED PLAN OF MERGER Proposed Merger On February 27, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Chevron Corporation, a Delaware corporation (''Parent'') and Cyclone Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Subsidiary” and, together with Parent, “Buyer”). The Merger Agreement provides that, among other things, at the Effective Time (as defined in the Merger Agreement) and subject to the terms and conditions set forth therein, that Merger Subsidiary will be merged with and into the Company (the "Merger"), with the Company surviving as a wholly owned subsidiary of Parent. At the Effective Time, each share of the Company's common stock issued and outstanding immediately prior to the Effective Time (other than Cancelled Shares (as defined in the Merger Agreement) and Dissenting Shares (as defined in the Merger Agreement)), will be converted into the right to receive $61.50 in cash, without interest (the "Merger Consideration"). At the Effective Time, and as a result of the Merger: • Each outstanding stock appreciation right with respect to a share of common stock (each, a "Company SAR") (all of which had previously vested prior to the date of the Merger Agreement) will vest and be cancelled and converted into the right to receive a cash payment, less any applicable withholding taxes, equal to the product of (x) the excess, if any, of the Merger Consideration over the exercise price applicable to such Company SAR multiplied by (y) the number of shares of common stock subject to such Company SAR. • Each outstanding restricted stock unit award that vests solely on the passage of time held by a Company non-employee director (each, a "Company Director RSU") will vest and be cancelled and converted into the right to receive a cash payment, less any applicable withholding taxes, equal to the product of (x) the Merger Consideration multiplied by (y) the number of shares of common stock subject to such Company Director RSU. • Each outstanding restricted stock unit award that vests solely on the passage of time and is not a Company Director RSU (each, a "Company Employee RSU Award") to the extent vested immediately prior to the Effective Time will be cancelled and converted into the right to receive a cash payment, less any applicable withholding taxes, equal to the product of (x) the Merger Consideration multiplied by (y) the number of vested shares of common stock subject to such Company Employee RSU Award. • Each outstanding Company Employee RSU Award to the extent unvested immediately prior to the Effective Time (each, an "Unvested Company Employee RSU Award") and certain performance-based restricted stock unit awards set forth on a schedule to the Merger Agreement (the "Scheduled PSU Awards") will be cancelled and converted into the right to receive an amount in cash, less any applicable withholding taxes, equal to the product of (x) the Merger Consideration multiplied by (y) the number of shares of common stock subject to such Unvested Company Employee RSU Award or Scheduled PSU Award, as applicable (such converted award, an "Assumed RSU Award"). Each Assumed RSU Award will be subject to the vesting schedule applicable to the corresponding Unvested Company Employee RSU Award immediately prior to the Effective Time (including, with respect to the Scheduled PSU Awards, the performance vesting conditions). • Except with respect to the Scheduled PSU Awards, each outstanding restricted stock unit award that corresponds to shares of common stock granted under any Company Benefit Plan and vests based on the achievement of performance goals (each a "Company PSU Award") will be cancelled and converted into the right to receive an amount in cash, without interest and less any applicable withholding taxes, equal to the product of (A) the Merger Consideration multiplied by (B) the number of shares of common stock subject to such Company PSU Award (assuming that any performance based vesting conditions applicable to such Company PSU Award for any performance period that has not been completed as of the Effective Time are achieved at (x) with respect to Company PSU Awards granted in 2020 and 2021, the greater of the target performance levels and the levels based on actual achievement of pro-rated performance goals through the Effective Time or (y) with respect to Assumed PSU Awards, the target performance levels. Each Assumed PSU Award will be subject to the vesting schedule applicable to the corresponding Company PSU Award immediately prior to the Effective Time (other than any performance based vesting conditions). The closing of the Merger is subject to various conditions, including (i) the adoption of the Merger Agreement by holders of a majority of the issued and outstanding shares of our common stock; (ii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR Act") and clearance by the European Commission or expiration of any applicable waiting period, in each case under EU Regulation 139/2004 (the "EU Clearance"); (iii) the absence of any order or law prohibiting the consummation of the Merger, except if such order or law is immaterial to Parent and (iv) the accuracy of the representations and warranties contained in the Merger Agreement, subject to customary materiality qualifications, as of the date of the Merger Agreement and as of the closing of the Merger, and compliance in all material respects with the covenants and agreements contained in the Merger Agreement. In addition, the obligation of Parent and Merger Subsidiary to consummate the Merger is subject to the absence, since the date of the Merger Agreement, of a Company Material Adverse Effect (as defined in the Merger Agreement). The closing of the Merger is not subject to a financing condition. Under the terms of the Merger Agreement, consummation of the Merger will occur on the second business day following the fulfillment or waiver of the conditions to closing of the Merger or at such other time as REG and Parent agree. The HSR Act waiting period expired on April 11, 2022. The Company's Board of Directors and the board of directors of Merger Subsidiary have each unanimously approved the Merger and the Merger Agreement. Until the closing, the Company will continue to operate as an independent, public company.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2022
Accounting Policies [Abstract]
Accounting for Business Combinations	Accounting for Business Combinations The Company accounts for business combinations under the acquisition method of accounting. This method requires the recording of acquired assets, including separately identifiable intangible assets, and assumed liabilities at their acquisition date fair values. The excess of the purchase price over the fair value of assets acquired and liabilities assumed is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash flows, discount rates, royalty rates and asset lives, among other items.
Restricted Cash	Restricted Cash The Company segregates certain cash balances as restricted cash that represent those funds required to be set aside by a contractual agreement. The Company classifies restricted cash between current and non-current assets based on the length of time of the restricted use.
Marketable Securities	Marketable Securities The Company's marketable securities are classified as available-for-sale and are reported at fair value, with unrealized gains and losses, net of tax, recorded in accumulated other comprehensive income (loss). The Company classifies its marketable securities as either current or long-term based on each instrument's underlying contractual maturity date. Realized gains or losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are reported in other income, net. The Company evaluates such investments periodically for possible other-than-temporary impairment. A decline of fair value below amortized costs of debt securities is considered an other-than-temporary impairment if the Company has the intent to sell the security or if it is more likely than not that the Company will be required to sell the security before recovery of the entire amortized cost basis. In those instances, an impairment charge equal to the difference between the fair value and the amortized cost basis is recognized in earnings. Regardless of the Company's intent or requirement to sell a debt security, an impairment is considered other-than-temporary if the Company does not expect to recover the entire amortized cost basis; in those instances, a credit loss equal to the difference between the present value of the cash flows expected to be allocated based on credit risk and the amortized cost basis of the debt security is recognized in earnings. The Company has no current requirement or intent to sell a material portion of marketable securities as of March 31, 2022. The Company expects to recover up to (or beyond) the initial cost of investment for securities held. In computing realized gains and losses on available-for-sale securities, the Company determines cost based on amounts paid, including direct costs such as commissions to acquire the security, using the specific identification method.
Renewable Identification Numbers (RINs)	Renewable Identification Numbers ("RINs") When the Company produces and sells a gallon of bio-based diesel for use in the United States, 1.5 to 1.7 RINs per gallon are generated. RINs are used to track compliance with the Renewable Fuel Standard, using the EPA moderated transaction system. RFS2 allows the Company to attach between zero and 2.5 RINs to any gallon of bio-based diesel. As a result, a portion of the selling price for a gallon of bio-based diesel sold in the U.S. is generally attributable to RFS2 compliance. However, RINs that the Company generates are a form of government incentive and not a result of the physical attributes of the bio-based diesel production. Therefore, no cost is allocated to the RIN when it is generated, regardless of whether the RIN is transferred with the bio-based diesel produced or held by the Company pending attachment to other bio-based diesel production sales. Additionally, RINs, once obtained through the production and sale of gallons of bio-based diesel, may be separated by the acquirer and sold separately. In addition, the Company also obtains RINs from third parties who have separated the RINs from gallons of bio-based diesel. From time to time, the Company holds varying amounts of these separated RINs for resale. RINs obtained from third parties are initially recorded at their cost and are subsequently revalued at the lower of cost or net realizable value as of the last day of each accounting period. The resulting adjustments are reflected in costs of goods sold for the period. The value of these RINs is reflected in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheets. The cost of goods sold related to the sale of these RINs is determined using the average cost method, while market prices are determined by RIN values, as reported by the Oil Price Information Service ("OPIS").
Low Carbon Fuel Standard	Low Carbon Fuel Standard The Company generates LCFS credits for its low carbon fuels when its qualified low carbon fuels are transported into an LCFS market and sold for qualifying purposes. LCFS credits are used to track compliance with the LCFS. As a result, a portion of the selling price for a gallon of bio-based diesel sold into an LCFS market is also attributable to LCFS compliance. However, LCFS credits that the Company generates are a form of government incentive and not a result of the physical attributes of the bio-based diesel production. Therefore, no cost is allocated to the LCFS credit when it is generated, regardless of whether the LCFS credit is transferred with the bio-based diesel produced or held by the Company. In addition, the Company also obtains LCFS credits from third-party trading activities. From time to time, the Company holds varying amounts of these third-party LCFS credits for resale. LCFS credits obtained from third parties are initially recorded at their cost and are subsequently revalued at the lower of cost or net realizable value as of the last day of each accounting period, and the resulting adjustments are reflected in costs of goods sold for the period. The value of LCFS credits obtained from third parties is reflected in “Prepaid expenses and other assets” on the Condensed Consolidated Balance Sheet. The cost of goods sold related to the sale of these LCFS credits is determined using the average cost method, while market prices are determined by LCFS values, as reported by the OPIS. The Company records assets acquired and liabilities assumed through the exchange of non-monetary assets based on the fair value of the assets and liabilities acquired or the fair value of the consideration exchanged, whichever is more readily determinable.
Impairment of Long-Lived Assets	Impairment of Long-lived Assets The Company tests its long-lived assets for recoverability when events or circumstances indicate that its carrying amount may not be recoverable. Significant assumptions used in the undiscounted cash flow analysis, when it is required, include the projected demand for biomass-based diesel based on annual renewable fuel volume obligations under the Renewable Fuel Standards ("RFS2"), the Company's capacity to meet that demand, the market price of biomass-based diesel and the cost of feedstock used in the manufacturing process. During the three months ended March 31, 2022, the Company recorded impairment charges of $2,748 related to certain property, plant and equipment due to the change in the intent to utilize these assets and that the carrying amounts of these assets deemed not recoverable given the assets' deteriorating physical conditions identified during the period. During the first quarter of 2021, the Company recorded impairment charges of $822 related to certain equipment as the carrying amounts of these assets were deemed not recoverable given the assets' deteriorating physical conditions identified during the period.
Green Notes	Green Notes On May 20, 2021, the Company completed the sale and issuance of $550,000 aggregate principal amount of 5.875% senior secured notes due in 2028 (the "Green Notes"). The Company recorded $14,619 in legal, professional and underwriting fees related to the issuance of the Green Notes. The Company currently intends to use the net proceeds from this offering for capital expenditures related to the improvement and expansion of its Geismar, Louisiana biorefinery. See "Note 8—Debt" for a further description of the Green Notes.
Security Repurchase Programs	Security Repurchase ProgramIn February 2020, the Company's Board of Directors approved a repurchase program of up to $100,000 of the Company's shares of common stock and/or its previously outstanding convertible notes (the "2020 Program"). Under this program, the Company may repurchase shares from time to time in open market transactions, privately negotiated transactions or by other means. The timing and amount of repurchase transactions under the program are determined by the Company's management based on its evaluation of market conditions, share price, legal requirements and other factors.
Revenue Recognition	Revenue Recognition The Company generally has a single performance obligation in its arrangements with customers. The Company believes for most of its contracts with customers, control is transferred at a point in time, typically upon delivery to the customers. When the Company performs shipping and handling activities after the transfer of control to the customers (e.g., when control transfers prior to delivery), they are considered as fulfillment activities, and accordingly, the costs are accrued for when the related revenue is recognized. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues. The Company generally expenses sales commissions when incurred because the amortization period would have been less than one year. The Company records these costs within selling, general and administrative expenses. The following is a description of principal activities from which we generate revenue. Revenues from contracts with customers are recognized when control of the promised goods or services are transferred to our customers, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. • sales of biodiesel and RD produced at our facilities, including RINs and LCFS credits; • resale of biodiesel, RD and petroleum and petroleum-based products acquired from third parties, along with the sale of RD and petroleum-based products further blended with biodiesel produced at our wholly owned facilities or acquired from third parties; • sales of separated RINs and LCFS credits; • sales of raw materials, glycerin and other co-products of the bio-based diesel production process; • other revenue, including bio-based diesel facility management and operational services; and • incentive payments from federal and state governments, including the BTC, and from the USDA Advanced Biofuel Program. Disaggregation of revenue:
New Accounting Standards	New Accounting Standards On March 12, 2020, the FASB issued ASU 2020-04, which provides a relief that is elective and applies to all entities, subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. Optional expedients are provided for contract modification accounting under the following Codification topics and subtopics: ASC 310, Receivables; ASC 470, Debt; ASC 840 or ASC 842, Leases; and ASC 815-15, Derivatives and Hedging: Embedded Derivatives. The ASU also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. T he amendments in ASU 2020-04 are effective for all entities as of March 12, 2020, through December 31, 2022. The Company has determined that the impact of the guidance on its condensed consolidated financial statements is not material. On August 5, 2020, the FASB issued ASU 2020-06, which reduces the complexity of the accounting for convertible debt instruments and its effect on earnings per share calculation. The guidance reduces the number of accounting models used for convertible debt instruments, which will result in fewer embedded conversion features being recognized separately from the original contract. This will also affect the guidance associated with convertible debt for earnings-per-share by requiring the if-converted method rather than the treasury stock method, requiring that potential share settlement be included in the calculation of diluted earnings per share and clarifying that an entity should use the weighted-average share count from each quarter when calculating the year-to-date weighted-average share count. For public business entities, the amendments in ASU 2020-06 are effective for fiscal years beginning after December 15, 2021, including interim periods within those years, and early adoption is permitted for fiscal years beginning after December 15, 2020, including interim periods within those years. The Company has determined that the guidance has no material impact on its condensed consolidated financial statements. On October 28, 2021, the FASB issued ASU 2021-08, which updates the guidance related to the acquisition of revenue contracts in a business combination. The new guidance requires that the acquiring entity recognize and measure contract assets and liabilities acquired in a business combination in accordance with Topic 606. At the acquisition date the acquirer should recognize the contract assets and liabilities under Topic 606 as they would have been recognized at contract origination rather than at fair value at the time of the acquisition. The intent is to create more comparability of recognition and measurement of the acquired contracts in business combinations. For public business entities, the amendments in ASU 2021-08 are effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. The Company is evaluating the impact of the guidance on its condensed consolidated finance statements. On November 17, 2021, the FASB issued ASU 2021-10, which requires business entities to provide certain disclosures when they (1) have received government assistance and (2) use a grant or contribution accounting model by analogy to other accounting guidance. The guidance will require business entities to disclose the nature of the transactions, accounting policies used to account for the transactions, and state which line items on the balance sheet and income statement are affected by these transactions and the amount applicable to each financial statement line. Business entities will also have to disclose significant terms and conditions of transactions with a government such as the duration of the agreement, any commitments made by either side, provisions, and contingencies. The guidance in ASU 2021-10 is effective for all entities for fiscal years beginning after December 15, 2021. Entities may apply the provision either (1) prospectively to all transactions within the scope of ASC 832 that are reflected in the financial statements as of the adoption date and all new transactions entered into after the date of adoption or (2) retrospectively. Early adoption is permitted. The Company has determined that the impact of the guidance on its condensed consolidated financial statements is not material. On March 28, 2022, the FASB issued ASU 2022-01, which updates the guidance related to the optional hedge accounting model. The guidance better portrays the economic results of an entity's risk management activities in its financial statements by expanding the scope of ASU 2017-12. The expansion allows for multiple hedged layers to be designated for a single closed portfolio of financial instruments or one or more beneficial interests secured by a portfolio of financial instruments, which is referred to as a portfolio layer method hedge. As a result, an entity can achieve hedge accounting for hedges of a greater proportion of the interest rate risk inherent in the assets included in the closed portfolio. The guidance for ASU 2022-10 is effective for public business entities December 15, 2022. Upon adoption, The Company must decide within 30 days which securities already in closed portfolios will be designated in a portfolio layer method hedge. The Company is evaluating the impact of guidance on its condensed consolidated financial statements.
