Organization, Consolidation and Presentation of Financial Statements [Abstract]
Formation of the Partnership, Organization and Nature of Business	(1) Formation of the Partnership, Organization and Nature of Business CVR Partners, LP (referred to as "CVR Partners" or the "Partnership") is a Delaware limited partnership, formed in June 2007 by CVR Energy, Inc. (together with its subsidiaries, but excluding the Partnership and its subsidiaries, "CVR Energy") to own Coffeyville Resources Nitrogen Fertilizers, LLC ("CRNF"), previously a wholly-owned subsidiary of CVR Energy. CRNF is an independent producer and marketer of upgraded nitrogen fertilizer products sold in North America. CRNF operates a dual-train coke gasifier plant that produces high-purity hydrogen, most of which is subsequently converted to ammonia and upgraded to urea ammonium nitrate ("UAN"). CRNF produces and distributes nitrogen fertilizer products, which are used primarily by farmers to improve the yield and quality of their crops. CRNF's principal products are UAN and ammonia. These products are manufactured at CRNF's facility in Coffeyville, Kansas. CRNF's product sales are heavily weighted toward UAN and all of its products are sold on a wholesale basis. Initial Public Offering of CVR Partners, LP Common Units On April 13, 2011, CVR Partners completed its initial public offering (the "Initial Public Offering") of 22,080,000 common units priced at $16.00 per unit. The common units, which are listed on the New York Stock Exchange, began trading on April 8, 2011 under the symbol "UAN." The net proceeds to CVR Partners from the Initial Public Offering were approximately $324.2 million, after deducting underwriting discounts and commissions and offering expenses. The net proceeds from the Initial Public Offering were used to make certain distributions, purchase (and subsequently extinguish) the incentive distribution rights owned by the Partnership's general partner, pay fees resulting from the credit facility, and the balance was used for or will be used for general partnership purposes, including the UAN expansion, and approximately $47.0 million which was used to fund profit and growth capital expenses in addition to the UAN expansion since the Initial Public Offering. Immediately subsequent to the closing of the Initial Public Offering, common units held by public security holders represented approximately 30% of the Partnership's outstanding limited partner interests and Coffeyville Resources, LLC ("CRLLC"), a wholly-owned subsidiary of CVR Energy, held common units approximating 70% of the Partnership's outstanding limited partner interests and 100% of the Partnership's general partner interest. Secondary Offering of CVR Partners, LP Common Units On May 28, 2013, CRLLC completed a registered public offering (the "Secondary Offering") whereby CRLLC sold 12,000,000 of the Partnership’s common units to the public at a price of $25.15 per unit. The net proceeds to CRLLC from the Secondary Offering were approximately $292.6 million, after deducting approximately $9.2 million in underwriting discounts and commissions. The Partnership did not receive any of the proceeds from the sale of common units by CRLLC. In connection with the Secondary Offering, the Partnership incurred approximately $0.5 million in offering costs during the year ended December 31, 2013. Immediately subsequent to the closing of the Secondary Offering and as of December 31, 2015 and 2014, common units held by public security holders represented approximately 47% of the Partnership's outstanding limited partner interest and CRLLC held common units approximating 53% of the Partnership's outstanding limited partner interests and 100% of the Partnership's general partner interests. Immediately subsequent to the completion of the pending mergers, which are discussed in the "Pending Mergers" section below, the Partnership estimates that CRLLC will hold common units approximating 34% of the Partnership's outstanding limited partner interests and 100% of the Partnership's general partner interest. CVR Energy Transaction Agreement On April 18, 2012, CVR Energy entered into a Transaction Agreement (the "Transaction Agreement") with an affiliate of Icahn Enterprises L.P. ("IEP"). Pursuant to the Transaction Agreement, IEP's affiliate offered (the "Offer") to purchase all of the issued and outstanding shares of CVR Energy’s common stock. On May 7, 2012, IEP's affiliate announced that control of CVR Energy had been acquired through the Offer. As of December 31, 2015 and 2014, IEP and its affiliates owned approximately 82% of the outstanding shares of CVR Energy common stock. Management and Operations CVR GP, LLC ("CVR GP" or the "general partner") manages and operates the Partnership. Common unitholders have only limited voting rights on matters affecting the Partnership. In addition, common unitholders have no right to elect the general partner's directors on an annual or continuing basis. The Partnership is operated by a combination of the general partner's senior management team and CVR Energy's senior management team pursuant to a services agreement among CVR Energy, CVR GP and the Partnership. In October 2007, the Partnership's partners at that time entered into an amended and restated limited partnership agreement setting forth their various rights and responsibilities. The Partnership also entered into a number of agreements with CVR Energy and CVR GP to regulate certain business relations between the Partnership and the other parties thereto. Certain of these agreements, including the amended and restated limited partnership agreement, have subsequently been amended and/or restated. See Note 14 ("Related Party Transactions") for further discussion. Pending Mergers On August 9, 2015, CVR Partners, including its two newly-created direct wholly-owned subsidiaries Lux Merger Sub 1 LLC ("Merger Sub 1") and Lux Merger Sub 2 LLC ("Merger Sub 2"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Rentech Nitrogen Partners, L.P., a publicly traded partnership whose common units are listed on the New York Stock Exchange under the ticker symbol "RNF" ("Rentech Nitrogen"), and Rentech Nitrogen GP, LLC ("Rentech Nitrogen GP"), pursuant to which CVR Partners will acquire Rentech Nitrogen and Rentech Nitrogen GP. The Merger Agreement provides that, upon the terms and subject to the conditions set forth therein, Merger Sub 1 will be merged with and into Rentech Nitrogen GP, with Rentech Nitrogen GP continuing as the surviving entity and a wholly-owned subsidiary of CVR Partners, and Merger Sub 2 will be merged with and into Rentech Nitrogen, with Rentech Nitrogen continuing as the surviving entity and a wholly-owned subsidiary of CVR Partners (together, the "mergers"). Under the terms of the Merger Agreement, holders of common units representing limited partner interests in Rentech Nitrogen ("Rentech Nitrogen common units") eligible to receive consideration will receive 1.04 common units (the "unit consideration") representing limited partner interests in CVR Partners ("CVR Partners common units") and $2.57 in cash, without interest, (the "cash consideration" and together with the unit consideration, the "merger consideration") for each Rentech Nitrogen common unit. Phantom units granted and outstanding under Rentech Nitrogen’s equity plans and held by an employee who will continue in the employment of a CVR Partners-affiliated entity upon closing of the mergers will be canceled and replaced with new incentive awards of substantially equivalent value and on similar terms. Each phantom unit granted and outstanding and held by (i) an employee who will not continue in employment of a CVR Partners-affiliated entity, or (ii) a director of Rentech Nitrogen GP will, upon closing of the mergers, vest in full and be entitled to receive the merger consideration. The unit consideration is fixed, and the number of units included in the merger consideration will not be adjusted to reflect changes in the price of Rentech Nitrogen common units or CVR Partners common units. CVR Partners is expected to issue approximately 40.7 million CVR Partners common units to former Rentech Nitrogen common unitholders pursuant to the mergers. Rentech Nitrogen owns and operates two fertilizer facilities. The facility located in East Dubuque, Illinois produces primarily ammonia and UAN using natural gas as the facility's primary feedstock. The facility located in Pasadena, Texas (the "Pasadena facility") produces ammonium sulfate, ammonium thiosulfate and sulfuric acid, using ammonia and sulfur as the facility's primary feedstocks. Rentech Nitrogen is required to sell or spin off its Pasadena facility as a condition to closing of the mergers (unless waived), and Rentech Nitrogen common unitholders may receive additional consideration for the Pasadena facility in the event such a sale or spin-off is consummated. The completion of the mergers is subject to satisfaction or waiver of closing conditions, including (i) the adoption of the Merger Agreement by holders of a majority of the outstanding Rentech Nitrogen common units, (ii) the effectiveness of a registration statement on Form S-4, (iii) the approval for listing of the CVR Partners common units issuable as part of the merger consideration on the New York Stock Exchange, (iv) the sale or spin-off by Rentech Nitrogen of Rentech Nitrogen’s Pasadena facility on terms specified in the Merger Agreement, (v) the absence of certain events of default under the indenture governing Rentech Nitrogen’s 6.5% Second Lien Senior Secured Notes due 2021 and (vi) other customary conditions. On February 15, 2016, the Merger Agreement was adopted by holders of a majority of the outstanding Rentech Nitrogen common units. On January 14, 2016, CVR Partners registration statement on Form S-4 with the Securities and Exchange Commission ("SEC") to register the CVR Partners common units issuable as part of the merger consideration was declared effective. The Merger Agreement includes customary restrictions on the conduct of the Partnership’s business prior to the completion of the mergers, generally requiring the Partnership to conduct its business in the ordinary course and subjecting the Partnership to a variety of specified limitations. In accordance with the terms of the Merger Agreement, beginning with the distribution for the third quarter of 2015 and until the closing of the mergers, the Partnership may not make or declare distributions in excess of available cash for distribution in respect of any quarter. The Merger Agreement contains certain termination rights for both CVR Partners and Rentech Nitrogen and further provides that upon termination of the Merger Agreement, under certain circumstances, either party may be required to make an expense reimbursement payment of $10.0 million, and Rentech Nitrogen may be required to pay CVR Partners a termination fee equal to $31.2 million. Simultaneously with the execution of the Merger Agreement, CVR Partners entered into a commitment letter (the "commitment letter") with CRLLC, pursuant to which CRLLC has committed to, on the terms and subject to the conditions set forth in the commitment letter, make available to CVR Partners term loan financing of up to $150.0 million, which amounts would be available solely to fund the repayment of all of the loans outstanding under Rentech Nitrogen’s existing $50.0 million credit facility with General Electric Capital Corporation, the cash consideration and expenses associated with the mergers. The term loan facility will bear interest at a rate of three-month LIBOR plus 3.0% per annum. Calculation of interest shall be on the basis of the actual number of days elapsed over a 360-day year. Such term loan, if drawn, would have a one year term. The Partnership incurred $2.3 million of legal and other professional fees and other merger related expenses, which were included in selling, general and administrative expenses (exclusive of depreciation and amortization) for the year ended December 31, 2015. See Note 13 ("Commitments and Contingencies") for discussion of litigation related to the pending mergers.
