Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization Business activities NGA HoldCo, LLC, a Nevada limited liability company (“NGA”), was formed on January 8, 2007 at the direction of Newport Global Opportunities Fund LP, a Delaware limited partnership (“NGOF”) and an affiliate of Newport Global Advisors LP, a Delaware limited partnership (“Newport”). NGA was formed for the primary purpose of holding equity, directly or indirectly through its subsidiaries, in one or more entities related to the gaming industry. The Company has two wholly owned subsidiaries, NGA Blocker, LLC, a Nevada limited liability company (“Blocker”), and AcquisitionCo, LLC, a Nevada limited liability company (“AcquisitionCo”), each of which was formed on January 8, 2007 (collectively with NGA, the “Company”). The Company has had no revenue generating business since inception. The Company's operations consist primarily of gaming industry related investments including its holding, through AcquisitionCo, of a 40% equity interest in Mesquite Gaming LLC, a Nevada limited liability company (“Mesquite”), a loan to Mesquite, and ownership of 4,030,440 publicly traded shares of Eldorado Resorts, Inc. ("ERI," formerly known as Eclair Holdings Company) common stock, $0.00001 par value, representing an approximate 8.6% ownership interest in ERI (the "ERI shares"). The ERI shares were acquired September 19, 2014, upon consummation of a merger between MTR Gaming, Inc. ("MTR") and Eldorado Holdco, LLC ("Eldorado"), a previously unconsolidated investee of the Company in which the Company held an approximate 17.0359% equity interest (the "ERI Merger"). ERI currently owns and operates (1) the Eldorado Hotel & Casino located in Reno, Nevada, (2) the Eldorado Resort Casino Shreveport located in Shreveport, Louisiana, (3) Scioto Downs Racino located in Columbus, OH, (4) Mountaineer Casino Racetrack & Resort located in Chester, WV, and (5) Presque Isle Downs & Casino located in Erie, PA, and owns an approximate 96% interest in an entity which owns a 50% interest in a joint venture that owns and operates the Silver Legacy Resort Casino (which is seamlessly connected to the Eldorado Hotel & Casino). Combined, the six properties contain approximately 3,300 hotel rooms, 240 table games, 40 restaurants, 7,800 slot machines and 2,150 video lottery terminals. Eldorado previously owned a 21.25% interest in Tamarack Crossing, LLC ("Tamarack") that owns and operates Tamarack Junction, a casino in south Reno. On September 1, 2014, and as a condition to closing the ERI Merger, Eldorado distributed on a pro-rata basis to its members (including the Company) its equity interest in Tamarack. The Company contemporaneously sold its equity interest in Tamarack for $1,350,000, the estimated fair value of the in-kind distribution. The Company's 40% Mesquite Interest was acquired August 1, 2011 (the “Mesquite Acquisition”), in exchange for $8,222,222 in cash, of which $7,222,222 and $1,000,000 were contributed to the Company by NGOF and Newport Global Credit Fund (“NGCF,” and collectively with NGOF, the “Newport Funds”), respectively. Mesquite is engaged in the casino resort industry in Mesquite, Nevada through wholly owned subsidiaries that own and operate the CasaBlanca Resort/Golf/Spa, the Virgin River Hotel/Casino/Bingo, two championship golf courses, a full-service spa, a bowling center, restaurants, and banquet and conference facilities. Mesquite also owns real estate on which another hotel & casino was located prior to its demolition in 2013. The Company has no current plans to acquire any equity interest in another entity. Formed in 2005, Newport is a Texas-based investment management firm focused on alternative fixed income strategies. The firm concentrates primarily on the stressed and distressed opportunities within the high yield debt and bank loan markets, but may also include the acquisition and disposition of other types of corporate securities and claims. Newport has 10 employees, with its primary office in The Woodlands, TX. Newport’s principals include Timothy T. Janszen, CEO, Ryan Langdon, Senior Managing Director, and Roger A. May, Senior Managing Director. Collectively, the principals have over 40 years of experience investing in the high yield and distressed debt markets. Newport is registered with the Securities and Exchange Commission (the "Commission") as an investment adviser under the Investment Advisers Act of 1940, as amended. Newport is investment manager of the Newport Funds, private investment funds which seek attractive long-term risk adjusted returns by capitalizing on investments in the distressed debt markets and possibly control-oriented investments. The Newport Funds began investing in 2006. Concentrations and economic uncertainties NGA and its consolidated subsidiaries expect to be economically dependent upon relatively few investments in the gaming industry. The United States recently experienced a recession accompanied by, among other things, weakness in the commercial and investment banking systems resulting in reduced credit and capital financing availability, and highly curtailed gaming, other recreational, construction and real estate market activities and general discretionary consumer spending. Although capital market activity and liquidity are reported to have improved of late, the recovery from this recession period is fragile and there can be no assurance that the Company’s business and that of its investees, which have been severely affected by the downturn, will fully recover to pre-recession levels. In addition, the Company carries cash on deposit with financial institutions substantially in excess of federally-insured limits. The extent of any loss that might be incurred as a result of uninsured deposits in the event of a future failure of a bank or other financial institutions is not subject to estimation at this time.
