Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	NOTE 1 — ORGANIZATION Organization. MGM Resorts International (together with its consolidated subsidiaries, unless otherwise indicated or unless the context requires otherwise, the “Company”) is a Delaware corporation that acts largely as a holding company and, through subsidiaries, owns and operates casino resorts. As of March 31, 2020, the Company owns and operates the following integrated casino, hotel and entertainment resorts in Las Vegas, Nevada: Bellagio, MGM Grand Las Vegas, The Mirage, Mandalay Bay, Luxor, New York-New York, Park MGM and Excalibur. Operations at MGM Grand Las Vegas include management of The Signature at MGM Grand Las Vegas. The Company owns and operates along with local investors, MGM Grand Detroit in Detroit, Michigan, MGM National Harbor in Prince George’s County, Maryland, and MGM Springfield in Springfield, Massachusetts. The Company also owns and operates Borgata located on Renaissance Pointe in the Marina area of Atlantic City, New Jersey, Empire City in Yonkers, New York, MGM Northfield Park in Northfield Park, Ohio, and the following resorts in Mississippi: Beau Rivage in Biloxi and Gold Strike in Tunica. Additionally, the Company owns and operates the Park, a dining and entertainment district located between New York-New York and Park MGM, Shadow Creek, an exclusive world-class golf course located approximately ten miles north of its Las Vegas Strip Resorts, Primm Valley Golf Club at the California/Nevada state line and Fallen Oak golf course in Saucier, Mississippi. MGM Growth Properties LLC (“MGP”), a consolidated subsidiary of the Company, is organized as an umbrella partnership REIT (commonly referred to as an UPREIT) structure in which substantially all of its assets are owned by and substantially all of its businesses are conducted through MGM Growth Properties Operating Partnership LP (the “Operating Partnership”). MGP has two classes of authorized and outstanding voting common shares (collectively, the “shares”): Class A shares and a single Class B share. The Company owns MGP’s Class B share, which does not provide its holder any rights to profits or losses or any rights to receive distributions from operations of MGP or upon liquidation or winding up of MGP. MGP’s Class A shareholders are entitled to one vote per share, while the Company, as the owner of the Class B share, is entitled to an amount of votes representing a majority of the total voting power of MGP’s shares so long as the Company and its controlled affiliates’ (excluding MGP) aggregate beneficial ownership of the combined economic interests in MGP and the Operating Partnership does not fall below 30%. The Company and MGP each hold Operating Partnership units representing limited partner interests in the Operating Partnership. The general partner of the Operating Partnership is a wholly-owned subsidiary of MGP. The Operating Partnership units held by the Company are exchangeable into Class A shares of MGP on a one-to-one basis, or cash at the fair value of a Class A share, except as otherwise agreed to in connection with the waiver agreement discussed below. As of March 31, 2020, the Company owned 60.6% of the Operating Partnership units, and MGP held the remaining 39.4% ownership interest in the Operating Partnership. Pursuant to a master lease agreement between a subsidiary of the Company and a subsidiary of the Operating Partnership, the Company leases the real estate assets of The Mirage, Luxor, New York-New York, Park MGM, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit, Beau Rivage, Borgata, Empire City, MGM National Harbor, and MGM Northfield Park. Pursuant to a lease agreement between a subsidiary of the Company and a venture, 5% owned by such subsidiary and 95% owned by a subsidiary of Blackstone Real Estate Income Trust, Inc. (“BREIT”), the Company leases the real estate assets of Bellagio from such venture (the “Bellagio BREIT Venture”). Additionally, pursuant to a lease agreement between a subsidiary of the Company and MGP BREIT Venture (as defined below), a subsidiary of the Company leases the real estate assets of Mandalay Bay and MGM Grand Las Vegas from MGP BREIT Venture. Refer to Note 6 for further discussion of the leases. On February 14, 2020, the Company completed a series of transactions (collectively the “MGP BREIT Venture Transaction”) pursuant to which the real estate assets of MGM Grand Las Vegas and Mandalay Bay (including Mandalay Place) were contributed to a newly formed entity (“MGP BREIT Venture”), owned 50.1% by the Operating Partnership and 49.9% by a subsidiary of BREIT. In exchange for the contribution of the real estate assets, the Company received total consideration of $4.6 billion, which was comprised of $2.5 billion of cash, $1.3 billion of the Operating Partnership’s secured indebtedness assumed by MGP BREIT Venture, and the Operating Partnership’s 50.1% equity interest in the MGP BREIT Venture. In addition, the Operating Partnership issued approximately 3 million Operating Partnership units to the Company representing 5% of the equity value of MGP BREIT Venture. The Company recorded the difference between consideration received of $2.5 billion and the carrying value of the MGM Grand real estate assets of $733 million and selling costs of $27 million as a net gain on sale of assets of $1.7 billion, which is reflected within Gain on REIT transactions, net in the consolidated statements of operations. The Company also recorded the difference between consideration received of $2.1 billion and the carrying value of the Mandalay Bay real estate assets of $2.3 billion and selling costs of $11 million as a net loss on sale of assets of $252 million, which is reflected within Gain on REIT transactions, net in the consolidated statements of operations. In connection with the transactions, the Company provided a shortfall guaranty of the principal amount of indebtedness of the MGP BREIT Venture (and any interest accrued and unpaid thereon) as further discussed in Note 7. On the closing date, BREIT also purchased approximately 5 million MGP Class A shares for $150 million. In connection with the MGP BREIT Venture Transaction, MGP BREIT Venture entered into a lease with a subsidiary of the Company for the real estate assets of Mandalay Bay and MGM Grand Las Vegas as further discussed in Note 6. Additionally, the existing master lease with MGP was modified to remove the Mandalay Bay property and the annual rent under the MGP master lease was reduced by $133 million, as further discussed in Note 11. Also, on January 14, 2020, the Company, the Operating Partnership, and MGP entered into an agreement for the Operating Partnership to waive its right to issue MGP Class A shares, in lieu of cash, to the Company in connection with the Company exercising its right to require the Operating Partnership to redeem Operating Partnership units that the Company holds, at a price per unit equal to a 3% discount to the ten day average closing price prior to the date of the notice of redemption. The waiver was effective upon closing of the transaction on February 14, 2020 and terminates on the earlier of February 14, 2022 or the Company receiving cash proceeds of $1.4 billion as consideration for the redemption of the Company’s Operating Partnership units. The Company has an approximate 56% controlling interest in MGM China Holdings Limited (together with its subsidiaries, “MGM China”), which owns MGM Grand Paradise, S.A. (“MGM Grand Paradise”). MGM Grand Paradise owns and operates the MGM Macau resort and casino and MGM Cotai, an integrated casino, hotel and entertainment resort located on the Cotai Strip in Macau, as well as the related gaming subconcession and land concessions. The Company owns 50% of and manages CityCenter Holdings, LLC (“CityCenter”), located between Bellagio and Park MGM. The other 50% of CityCenter is owned by Infinity World Development Corp, a wholly owned subsidiary of Dubai World, a Dubai, United Arab Emirates government decree entity. CityCenter consists of Aria, an integrated casino, hotel and entertainment resort; and Vdara, a luxury condominium-hotel. See Note 3 for additional information related to CityCenter. The Company has three reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. See Note 10 for additional information about the Company’s segments. Financial Impact of COVID-19. The novel coronavirus (“COVID-19”) pandemic has caused, and is continuing to cause, significant disruption in the financial markets both globally and in the United States, and will continue to impact, possibly materially, our business, financial condition and results of operations. As of March 17, 2020, all of the Company’s domestic properties were temporarily closed to the public and have remained closed pursuant to state and local government requirements as a result of the unprecedented public health crisis from the COVID-19 pandemic. As a result, the Company’s domestic properties are effectively generating no revenue. In Macau, pursuant to a request from the government of Macau, MGM China suspended all operations at MGM Macau and MGM Cotai for a 15-day period that commenced on February 5, 2020, other than operations that were necessary to provide sufficient non-gaming facilities to serve any remaining hotel guests in that period. While the properties have since re-opened, several travel and entry restrictions in Macau, Hong Kong, and certain cities and regions in mainland China remain in place (including the temporary suspension of the visa scheme, the temporary suspension of ferry services and other modes of transportation, and bans on entry or enhanced quarantine requirements), significantly impacting visitation to the Company’s Macau properties, which continues to have a material impact on MGM China’s results of operations. The Company cannot predict the degree, or duration, to which its operations will be affected by the COVID-19 outbreak, and the effects could be material. Due to the continued impact of the outbreak of COVID-19, the Company and MGM China each entered into amendments to its credit agreement, as further discussed in Note 4.
