Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation In addition to the actions noted below, the Company and its affiliates are involved in litigation arising in the normal course of business. In the opinion of management, such litigation is not expected to have a material effect on the Company's financial condition, results of operations, and cash flows. Macau Litigation Related to Dore WRM has been named as a defendant in lawsuits filed in the Macau Court of First Instance by individuals who claim to be investors in or persons with credit in accounts maintained by Dore Entertainment Company Limited (“Dore”), an independent, Macau registered and licensed company that operated a gaming promoter business at Wynn Macau. In connection with the alleged theft, embezzlement, fraud and/or other crime(s) perpetrated by a former employee of Dore (the “Dore Incident”), the plaintiffs of the lawsuits allege that Dore failed to honor withdrawal of funds deposited with Dore as investments or gaming deposits that allegedly resulted in certain losses for these individuals. The principal allegations common to the lawsuits are that WRM, as a gaming concessionaire, should be held responsible for Dore’s conduct on the basis that WRM is responsible for the supervision of Dore’s activities at Wynn Macau that resulted in the purported losses. On November 19, 2021, the Macau Court of Final Appeal issued a final ruling (the “Ruling”) with respect to one such lawsuit that WRM was held jointly liable to a plaintiff. Pursuant to the Ruling, WRM was required to pay approximately $1.2 million, inclusive of accumulated interest, to such plaintiff. The Company believes most remaining cases are without merit and unfounded and intends to vigorously defend against the remaining claims pleaded against WRM in these lawsuits. The Company has made estimates for potential litigation costs based upon its assessment of the likely outcome and has recorded provisions for such amounts in the accompanying condensed consolidated financial statements. No assurances can be provided as to the outcome of the pending Dore cases, and actual results may differ from these estimates. Securities Action On February 20, 2018, a putative securities class action was filed against the Company and certain current and former officers of the Company in the United States District Court, Southern District of New York (which was subsequently transferred to the United States District Court, District of Nevada) by John V. Ferris and Joann M. Ferris on behalf of all persons who purchased the Company's common stock between February 28, 2014 and January 25, 2018. The complaint alleges, among other things, certain violations of federal securities laws and seeks to recover unspecified damages as well as attorneys' fees, costs and related expenses for the plaintiffs. On April 15, 2019, the Company filed a motion to dismiss, which the court granted on May 27, 2020, with leave to amend. On July 1, 2020, the plaintiffs filed an amended complaint. On August 14, 2020, the Company filed a motion to dismiss the amended complaint. On July 28, 2021, the court granted in part, and denied in part, the Company's motion to dismiss the amended complaint, dismissing certain of plaintiffs' claims, including all claims against Mr. Billings and the individual directors, and allowing other claims to proceed against the Company and several of the Company's former executive officers, including Mr. Maddox, Stephen A. Wynn, Kimmarie Sinatra, and Steven Cootey. The defendants in this action intend to vigorously defend against the claims pleaded against them. This action is in the preliminary stages and management has determined that based on proceedings to date, it is currently unable to determine the probability of the outcome of these actions or reasonably estimate the range of possible loss, if any. Federal Investigation From time to time, the Company receives regulatory inquiries about compliance with anti-money laundering laws. The Company received requests for information from the U.S. Attorney’s Office for the Southern District of California relating to its anti-money laundering policies and procedures, and beginning in 2020 received several grand jury subpoenas regarding various transactions at Wynn Las Vegas relating to certain patrons and agents who reside or operate in foreign jurisdictions. The Company continues to cooperate with the U.S. Attorney's Office in its investigation, which remains ongoing. Because no charges or claims have been brought, the Company is unable to predict the outcome of the investigation, the extent of the materiality of the outcome, or reasonably estimate the possible range of loss, if any, which could be associated with the resolution of any possible charges or claims that may be brought against the Company.
