Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Nature of Business	(1) Organization and Nature of Business Organization CVR Energy, Inc. (“CVR Energy,” “CVR,” “we,” “us,” “our,” or the “Company”) is a diversified holding company primarily engaged in the petroleum refining and nitrogen fertilizer manufacturing industries through its holdings in CVR Refining, LP (the “Petroleum Segment” or “CVR Refining”) and CVR Partners, LP (the “Nitrogen Fertilizer Segment” or “CVR Partners”). CVR Refining is an independent petroleum refiner and marketer of high value transportation fuels. CVR Partners produces and markets nitrogen fertilizers in the form of urea ammonium nitrate (“UAN”) and ammonia. CVR’s common stock is listed on the New York Stock Exchange (“NYSE”) under the symbol “CVI.” Icahn Enterprises L.P. and its affiliates (“IEP”) owned approximately 71% of the Company’s outstanding common shares as of December 31, 2020. Stock Repurchase Program On October 23, 2019, the Board of Directors authorized a stock repurchase program (the “Stock Repurchase Program”). The Stock Repurchase Program enables the Company to repurchase up to $300 million of the Company’s common stock. Repurchases under the Stock Repurchase Program may be made from time-to-time through open market transactions, block trades, privately negotiated transactions or otherwise in accordance with applicable securities laws. The timing, price and amount of repurchases (if any) will be made at the discretion of management and are subject to market conditions as well as corporate, regulatory and other considerations. While the Stock Repurchase Program currently has a duration of four years, it does not obligate the Company to acquire any stock and may be terminated by the Board of Directors at any time. We did not repurchase any of our common stock during the year ended December 31, 2020. CVR Refining, LP On January 17, 2019, the general partner of CVR Refining assigned to the Company its right to purchase all of the issued and outstanding CVR Refining common units not already owned by CVR Refining’s general partner or its affiliates. On January 29, 2019, the Company purchased all remaining CVR Refining common units not already owned by the Company or its affiliates for a cash purchase price of $10.50 per unit (the “Call Price”), or approximately $241 million in the aggregate (the “Public Unit Purchase”). In conjunction with the exercise of its call right for all CVR Refining common units not already owned by the Company or its affiliates, the Company entered into a purchase agreement with American Entertainment Properties Corporation (“AEP”) and IEP, pursuant to which, on January 29, 2019, all of the Common Units held by AEP and IEP were purchased by the Company for a cash price per unit equal to the Call Price, or approximately $60 million in the aggregate (the “Affiliate Unit Purchase” together with the Public Unit Purchase, the “CVRR Unit Purchase”). The total purchase price of $301 million was funded with approximately $105 million in borrowings under a new credit agreement entered into by the Company on January 29, 2019, with the remaining amount being funded from the Company’s cash on hand. Amounts drawn under the new credit agreement were fully repaid in February 2019. See Note 6 (“Long-Term Debt and Finance Lease Obligations”) for further information on the credit agreement. The consolidated results of operations and financial position of CVR Refining are reflected as CVR’s Petroleum Segment. Following this transaction, CVR Refining became a wholly-owned subsidiary of the Company and, therefore, is no longer accounted for as a variable interest entity (“VIE”). Effective February 8, 2019, CVR Refining’s reporting obligations under the Exchange Act were suspended. CVR Partners, LP Interest Holders - As of December 31, 2020, public common unitholders held approximately 64% of CVR Partners’ outstanding common units, and CVR Services, LLC (“CVR Services”) (formerly Coffeyville Resources, LLC), a wholly-owned subsidiary of CVR Energy, held approximately 36% of CVR Partners’ outstanding common units. In addition, CVR Services held 100% of CVR Partners’ general partner, CVR GP, LLC (“CVR GP”), which held a non-economic general partner interest in CVR Partners as of December 31, 2020. Following the acquisition of the non-controlling interest in CVR Refining in January 2019, the non-controlling interest reflected on the consolidated balance sheets of CVR is only impacted by the net income of, and distributions from, CVR Partners. NYSE Listing Requirements and Reverse Split - On April 20, 2020, the average closing price of CVR Partners’ common units over a 30 consecutive trading-day period fell below $1.00 per common unit, resulting in noncompliance with the continued listing compliance standards in Section 802.01C of the NYSE Listed Company Manual. CVR Partners received written notification of this noncompliance from the NYSE on April 22, 2020, and had until January 1, 2021 to regain compliance or be subject to the NYSE’s suspension and delisting procedures. See the Form 8-K filed by CVR Partners with the SEC on April 24, 2020 for further discussion. On November 2, 2020, CVR Partners announced that the board of directors of its general partner (the "UAN GP Board") approved a 1-for-10 reverse split of CVR Partners’ common units that was completed on November 23, 2020, pursuant to which each ten common units of CVR Partners would be converted into one common unit of the CVR Partners (the “Reverse Unit Split”). In accordance with CVR Partners’ Agreement of Limited Partnership, as amended, following the Reverse Unit Split, any fractional units of record holders were rounded up or down, as applicable, to the nearest whole common unit, with any fraction equal to or above 0.5 common units rounding up to the next higher common unit. Following the Reverse Unit Split, the number of CVR Partners common units outstanding decreased from approximately 111 million common units to approximately 11 million common units, with proportionate adjustments to the common units under CVR Partners’ long-term incentive plan and outstanding awards thereunder. CVR Partners’ common units began trading on a split-adjusted basis when markets opened on November 24, 2020, under the symbol “UAN” and a new CUSIP number. The reverse split enabled the Partnership to regain compliance with NYSE listing requirements on November 30, 2020, in advance of the January 1, 2021 deadline. Unit Repurchase Program - On May 6, 2020, the UAN GP Board, on behalf of CVR Partners, authorized a unit repurchase program (the “Unit Repurchase Program”). The Unit Repurchase Program enables CVR Partners to repurchase up to $10 million of its common units. During the year ended December 31, 2020, CVR Partners repurchased 623,177 common units, on the open market in accordance with a repurchase agreement under Rules 10b5-1 and 10b-18 of the Exchange Act, which was terminated on August 6, 2020, at a cost of $7 million, inclusive of transaction costs, or an average price of $11.35 per common unit. At December 31, 2020, CVR Partners had $3 million in authority remaining under the Unit Repurchase Program. On February 22, 2021, the UAN GP Board authorized an additional $10 million for the Unit Repurchase Program. This Unit Repurchase Program does not obligate CVR Partners to acquire any common units and may be cancelled or terminated by the UAN GP Board at any time. As a result of these repurchases, and the resulting change in CVR Energy’s ownership of CVR Partners while maintaining control, CVR Energy recognized an increase of $3 million to additional paid-in capital from the non-cash reduction of non-controlling interests totaling $4 million and the recognition of a deferred tax liability totaling $1 million from changes in its book versus tax basis in CVR Partners. Subsequent Events The Company evaluated subsequent events, if any, that would require an adjustment to the Company’s consolidated financial statements or require disclosure in the notes to the consolidated financial statements through the date of issuance of the consolidated financial statements. Where applicable, the notes to these consolidated financial statements have been updated to discuss all significant subsequent events which have occurred.
