Organization	(1) Organization *(a) Business and Organization* Antero Resources Corporation and its consolidated subsidiary (collectively referred to as the "Company," "we," or "our") are engaged in the exploitation, development, and acquisition of natural gas, natural gas liquids ("NGLs") and oil properties in the Appalachian Basin in West Virginia, Ohio, and Pennsylvania. We target large, repeatable resource plays where horizontal drilling and advanced fracture stimulation technologies provide the means to economically develop and produce natural gas, NGLs, and oil from unconventional formations. During 2012 we sold our Oklahoma Arkoma Basin properties and our Colorado Piceance Basin properties. We also have midstream gathering and water distribution operations in the Appalachian Basin. Our corporate headquarters are in Denver, Colorado. Our consolidated financial statements as of December 31, 2013 include the accounts of Antero Resources Corporation and its subsidiary, Antero Resources Midstream LLC. *(b) Corporate Reorganization and Initial Public Offering (IPO)* Prior to October 16, 2013, the Company's predecessor, Antero Resources LLC, filed reports with the Securities and Exchange Commission. Antero Resources LLC was formed in October 2009 by members of the Company's management team and its sponsor investors. Antero Resources LLC owned 100% of the outstanding shares of Antero Resources Appalachian Corporation, which was formed in March 2008 and renamed Antero Resources Corporation in June 2013. In connection with our initial public offering ("IPO") completed on October 16, 2013, all of the ownership interests in Antero Resources LLC were exchanged for similar interests in a newly formed limited liability company, Antero Resources Investment LLC ("Antero Investment"), and Antero Resources LLC was merged into Antero Resources Corporation. As a result of this reorganization, Antero Investment owned 100% of the issued and outstanding 224,375,000 shares of common stock of Antero Resources Corporation prior to the IPO. On October 16, 2013, Antero Resources Corporation issued 37,674,659 additional shares of its common stock at $44.00 per share in an IPO resulting in proceeds to the Company, net of underwriter discounts and expenses of the offering, of approximately $1.6 billion. Antero Investment also sold 3,409,091 shares of its common stock of Antero Resources Corporation in the IPO. The Company did not receive any of the proceeds from the sale of the shares by Antero Investment. In 2013, the Company formed a subsidiary, Antero Resources Midstream LLC ("Antero Midstream"). The Company owns all of the membership interests in Antero Midstream other than a special membership interest which is indirectly owned by Antero Investment. In connection with an initial public offering of Antero Midstream during 2014, the Company intends to contribute its midstream assets to Antero Midstream and enter into commercial arrangements for midstream services. The assets to be contributed consist of (i) low- and high-pressure natural gas gathering lines, (ii) fresh water distribution systems and (iii) compression facilities. The special membership interest in Antero Midstream provides Antero Investment with certain rights, including the right to cause an initial public offering of Antero Midstream as a master limited partnership ("MLP") or similar structure. Following any such initial public offering, the special membership interest will entitle Antero Investment to the general partner interest in the MLP, which will allow Antero Investment to manage Antero Midstream's business and affairs. Following any such initial public offering, Antero Investment will also hold incentive distribution rights in the MLP, which will represent the right to receive an increasing percentage of the MLP's quarterly cash distributions in excess of specified target distribution levels. *(c) Stock Compensation Charge in Connection with the Reorganization* In connection with the formation of Antero Resources LLC in October 2009, Antero Resources LLC issued profits interests to Antero Resources Employee Holdings LLC ("Employee Holdings"), which is owned solely by certain of our officers and employees. These profits interests provide for the participation in distributions upon liquidation events meeting certain requisite financial return thresholds. In turn, Employee Holdings issued membership interests to certain of our officers and employees. The Employee Holdings interests in Antero Resources LLC were exchanged for similar interests in Antero Investment on October 16, 2013. The limited liability company agreement of Antero Investment provides a mechanism by which the shares of the Company's common stock to be allocated among the members of Antero Investment, including Employee Holdings, will be determined. As a result of the adoption of the Antero Investment LLC agreement, the satisfaction of all performance and service conditions relative to the profits interests awards held by Employee Holdings in Antero Investment became probable. Accordingly, we recognized approximately $365 million of stock compensation expense for the vested profits interests through December 31, 2013 and will recognize an additional approximate $121 million over the remaining service period. Because consideration for the profits interests awards will be deemed given by Antero Investment, the charge to stock compensation expense is accounted for as a capital contribution by Antero Investment in the Company and credited to additional paid-in capital.
