Business and Organization |
Business and Organization | (1) Business and Organization Antero Midstream Partners LP (the “Partnership”) is a growth-oriented master limited partnership formed by Antero Resources Corporation (“Antero Resources”) to own, operate and develop midstream energy infrastructure primarily to service Antero Resources’ rapidly increasing production and completion activity in the Appalachian Basin’s Marcellus Shale and Utica Shale located in West Virginia and Ohio. The Partnership’s assets consist of gathering pipelines, compressor stations, and water handling and treatment assets, through which the Partnership provides midstream services to Antero Resources under long-term, fixed-fee contracts. The Partnership’s condensed consolidated financial statements as of June 30, 2017, include the accounts of the Partnership and its 100% owned operating subsidiaries: Antero Midstream LLC, Antero Water LLC (“Antero Water”), and Antero Treatment LLC. The condensed consolidated financial statements also include the accounts of Antero Midstream Finance Corporation (“Finance Corp”), a wholly owned subsidiary and the co-issuer of the Partnership’s senior notes. The Partnership’s 100% owned operating subsidiaries fully and unconditionally guarantee the Partnership’s outstanding debt securities on a joint and several basis. The Partnership has no independent assets or operations and there are no restrictions on the ability of the Partnership to obtain funds from its 100% owned subsidiaries by dividend or loan. The Partnership also has a 15% equity interest in the gathering system of Stonewall Gas Gathering LLC (“Stonewall”) and a 50% interest in a joint venture to develop processing and fractionation assets with MarkWest Energy Partners, L.P. (“MarkWest”). See Note 11 – Equity Method Investments. The Partnership’s financial statements are consolidated with the financial statements of Antero Resources (NYSE: AR), our primary beneficiary, for financial reporting purposes. On April 6, 2017, in connection with its initial public offering, Antero Resources Midstream Management LLC (“ARMM”) formed Antero Midstream Partners GP LLC (“AMP GP”), a Delaware limited liability company, as a wholly owned subsidiary, and, on April 11, 2017, assigned to AMP GP the general partner interest in us. Concurrent with the assignment, AMP GP was admitted as the Partnership’s sole general partner and ARMM ceased to be our general partner. On May 9, 2017, ARMM closed its initial public offering. In connection with the offering, ARMM was converted into a Delaware limited partnership, and changed its name to Antero Midstream GP LP (“AMGP”).
