The Company has a 50% equity interest in the joint venture to develop processing and fractionation assets with MarkWest Energy Partners, L.P. (“MarkWest”), a wholly owned subsidiary of MPLX, LP (the “Joint Venture”). The Joint Venture was formed to develop processing and fractionation assets in Appalachia. MarkWest operates the Joint Venture assets, which consist of processing plants in West Virginia and a one-third interest in two MarkWest fractionators in Ohio.

The Company also has a 15% equity interest in a gathering system of Stonewall Gas Gathering LLC (“Stonewall”), which operates a 67-mile pipeline on which Antero Resources is an anchor shipper.

The Company’s net income includes its proportionate share of the net income of the Joint Venture and Stonewall. When the Company records its proportionate share of net income, it increases equity income in the unaudited condensed consolidated statements of operations and comprehensive income and the carrying value of that investment on its condensed consolidated balance sheet. When distributions on the Company’s proportionate share of net income are received, they are recorded as reductions to the carrying value of the investment on the unaudited condensed consolidated balance sheet and are classified as cash inflows from operating activities in accordance with the nature of the distribution approach under Financial Accounting Standards Board Accounting Standard Codification Topic 230, Statement of Cash Flows. The Company uses the equity method of accounting to account for its investments in the Joint Venture and Stonewall because it exercises significant influence, but not control, over the entities. The Company’s judgment regarding the level of influence over its equity investments includes considering key factors such as its ownership interest, representation on the applicable Board of Directors and participation in policy-making decisions of the Joint Venture and Stonewall.
