Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 11. Commitments and Contingencies Litigation. The Company is a party to various lawsuits, which have arisen in the normal course of business. Estimated losses are accrued for these lawsuits and claims when the loss is probable and can be estimated. The current liability for the estimated losses associated with those lawsuits is not material to the consolidated financial condition and those estimated losses are not expected to have a material impact on the results of operations. In connection with the Isle Merger, a class action lawsuit was filed by a purported stockholder of the Company alleging breach of fiduciary duty by the Company board of directors in connection with the Isle Merger. The case was filed on November 8, 2016 in the Second Judicial District Court of the State of Nevada and is captioned Assad v. Eldorado Resorts, Inc., et. al, case no. CV 16-02312. The lawsuit, which purported to be a class action on behalf of all of the stockholders of the Company, alleged, among other things, breach of fiduciary duty in failing to disclose all material information to stockholders in seeking approval of the issuance of shares of Company Common Stock in the Isle Merger and requested injunctive relief. In the suit, the Plaintiff sought to enjoin the shareholder meeting to approve the sale. The request to enjoin the shareholder meeting lawsuit has since been withdrawn and, on May 31, 2017, the Court denied plaintiff’s application for an award of attorneys’ fees and expenses. The Company expects this matter to be dismissed. Agreements with Horsemen and Pari-mutuel Clerks. The Federal Interstate Horse Racing Act and the state racing laws in West Virginia, Ohio and Pennsylvania require that, in order to simulcast races, we have written agreements with the horse owners and trainers at those racetracks. In addition, in order to operate slot machines in West Virginia, we are required to enter into written agreements regarding the proceeds of the slot machines (a “proceeds agreement”) with a representative of a majority of the horse owners and trainers and with a representative of a majority of the pari‑mutuel clerks. In Pennsylvania and Ohio, we must have an agreement with the representative of the horse owners. We have the requisite agreements in place with the horsemen at Mountaineer until December 31, 2018. With respect to the Mountaineer pari‑mutuel clerks, we have a labor agreement in force until November 30, 2017, which will automatically renew for an additional one-year period, and a proceeds agreement until April 14, 2018. We are required to have a proceeds agreement in effect on July 1 of each year with the horsemen and the pari‑mutuel clerks as a condition to renewal of our video lottery license for such year. If the requisite proceeds agreement is not in place as of July 1 of a particular year, Mountaineer’s application for renewal of its video lottery license could be denied, in which case Mountaineer would not be permitted to operate either its slot machines or table games. Scioto Downs has the requisite agreement in place with the OHHA until December 31, 2023, with automatic two-year renewals unless either party requests re‑negotiation pursuant to its terms. Presque Isle Downs has the requisite agreement in place with the Pennsylvania Horsemen’s Benevolent and Protective Association until May 1, 2019. With the exception of the respective Mountaineer, Presque Isle Downs and Scioto Downs horsemen’s agreements and the agreement between Mountaineer and the pari‑mutuel clerks’ union described above, each of the agreements referred to in this paragraph may be terminated upon written notice by either party.
