Organization and Basis of Presentation	Note 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. On November 24, 2015 (the “Acquisition Date”), Resorts consummated the acquisition of all of the assets and properties of Circus Circus Reno (“Circus Reno”) and the 50% membership interest in the Silver Legacy Joint Venture owned by Galleon, Inc. (collectively, the “Circus Reno/Silver Legacy Purchase” or the “Acquisition”) pursuant to a Purchase and Sale Agreement, dated as of July 7, 2015 (the “Purchase Agreement”), entered into with Circus Circus Casinos, Inc. and Galleon, Inc., each an affiliate of MGM Resorts International, with respect to the acquisition. On the Acquisition Date, Eldorado Resorts LLC also exercised its right to acquire the 3.8% interest in Eldorado Limited Liability Company (“ELLC”) held by certain affiliates and shareholders of the Company. As a result of these transactions, ELLC and CC-Reno, LLC, a newly formed Nevada limited liability company, became wholly-owned subsidiaries of ERI, and Silver Legacy became an indirect wholly‑owned subsidiary of ERI. The accompanying consolidated financial statements for periods prior to the Acquisition Date do not include the results of operations for Circus Reno and account for Silver Legacy as an investment in unconsolidated affiliate. Resorts owns and operates the Eldorado Resorts Casino Reno, 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. Prior to the Acquisition Date, Resorts owned 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 Reno hotel and casino. Resorts acquired the remaining interest in Silver Legacy in 2015 as well as acquiring Circus Reno, previously owned and operated by Galleon, Inc., an indirect, wholly owned subsidiary of MGM Resorts International. 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, including members of the Carano family, 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.
