Organization and Basis of Presentation	1. Organization and Basis of Presentation The accompanying consolidated financial statements include the accounts of Eldorado Resorts, Inc. ("ERI" or the "Company"), a Nevada corporation formed in September 2013, and its consolidated subsidiaries. As explained in greater detail in Note 3, ERI was formed in September 2013 to be the parent company following the merger of wholly owned subsidiaries of the Company into Eldorado HoldCo LLC ("HoldCo"), a Nevada limited liability company formed in 2009 that is the parent company of Eldorado Resorts LLC ("Resorts"), and MTR Gaming Group, Inc. ("MTR Gaming"), a Delaware corporation incorporated in 1988 (the "Merger"). Effective upon the consummation of the Merger on September 19, 2014 (the "Merger Date"), MTR Gaming and HoldCo each became a wholly owned subsidiary of ERI and, as a result of such transactions, Resorts became an indirect wholly owned subsidiary of ERI. The Merger has been accounted for as a reverse acquisition of MTR Gaming by HoldCo under accounting principles generally accepted in the United States ("US GAAP"). As a result, HoldCo is considered the acquirer of MTR Gaming for accounting purposes. The accompanying consolidated financial statements for periods prior to the Merger Date are those of HoldCo and its subsidiaries, and for periods subsequent to the Merger Date also include MTR Gaming and its subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. Resorts owns and operates the Eldorado Hotel and Casino, a premier hotel, casino and entertainment facility centrally located in downtown Reno, Nevada (the "Eldorado Reno"), which opened for business in 1973. Resorts also owns Eldorado Resort Casino Shreveport ("Eldorado Shreveport"), a 403-room all suite art deco-style hotel and a tri-level riverboat dockside casino complex situated on the Red River in Shreveport, Louisiana, which commenced operations under its previous owners in December 2000. Resorts also owns a 48.1% interest in the joint venture (the "Silver Legacy Joint Venture") which owns the Silver Legacy Resort Casino (the "Silver Legacy"), a major themed hotel and casino situated between and seamlessly connected at the mezzanine level to the Eldorado Reno and Circus Circus-Reno, a hotel and casino owned and operated by Galleon, Inc. ("Galleon"), an indirect, wholly owned subsidiary of MGM Resorts International. Galleon owns 50% of the interests of the Silver Legacy Joint Venture. Pursuant to a Retained Interest Agreement entered into in connection with the Merger (see Note 5), Resorts has the right to acquire the remaining 1.9% interest in the Silver Legacy from Eldorado Limited Liability Company ("ELLC"), a Nevada limited liability company that was a 96% owned subsidiary of Resorts prior to the Merger, on the terms and conditions described therein. Resorts previously owned a 21.3% interest in Tamarack Crossing, LLC ("Tamarack"), a Nevada limited liability company that owned and operated Tamarack Junction, a casino in south Reno which commenced operations on September 4, 2001. On September 1, 2014, and as a condition to closing the Merger, Resorts distributed to HoldCo, and HoldCo subsequently distributed to its members on a pro rata basis Resorts' interest in Tamarack. No gain or loss was recognized in the accompanying consolidated financial statements as a result of such distribution because the distribution was in the amount of the book value of Tamarack and totaled $5.5 million. MTR Gaming operates as a hospitality and gaming company with racetrack, gaming and hotel properties in West Virginia, Pennsylvania and Ohio. MTR Gaming, through its wholly owned subsidiaries, owns and operates Mountaineer Casino, Racetrack & Resort in Chester, West Virginia ("Mountaineer"), Presque Isle Downs & Casino in Erie, Pennsylvania ("Presque Isle Downs"), and Scioto Downs in Columbus, Ohio.
