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 (the “NYSE”) under the symbol “CVI.” Icahn Enterprises L.P. and its affiliates (“IEP”) owned approximately 71% of the Company’s outstanding common stock as of June 30, 2021. CVR Partners, LP Interest Holders - As of June 30, 2021, 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 June 30, 2021. The noncontrolling interest reflected on the condensed consolidated balance sheets of CVR is only impacted by the net income of, and distributions from, CVR Partners. Unit Repurchase Program - On May 6, 2020, CVR Partners announced that the board of directors of its general partner (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. On February 22, 2021, the UAN GP Board authorized an additional $10 million for the Unit Repurchase Program. During the three months ended June 30, 2021, CVR Partners did not repurchase any common units. During the six months ended June 30, 2021, CVR Partners repurchased 24,378 common units on the open market in accordance with a repurchase agreement under Rules 10b5-1 and 10b-18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) at a cost of $0.5 million, inclusive of transaction costs, or an average price of $21.70 per common unit. During the three and six months ended June 30, 2020, as adjusted to reflect the impact of the 1-for-10 reverse unit split of the CVR Partners’ common units that was effective as of November 23, 2020, CVR Partners repurchased 89,022 common units at a cost of $1.0 million, inclusive of transaction costs, or an average price of $10.72 per common unit. As of June 30, 2021, CVR Partners had $12.4 million in authority remaining under 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 a nominal increase to additional paid-in capital from the reduction of non-controlling interests totaling $0.1 million and the recognition of a deferred tax liability totaling $0.1 million from changes in its book versus tax basis in CVR Partners as of June 30, 2021. 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 as of December 31, 2020.
