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 . 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.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2 — BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2019 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year. Principles of consolidation. For entities not determined to be a variable interest entity (“VIE”), the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity if it has the direct or indirect ability to control the entities’ activities based upon the terms of the respective entities’ ownership agreements, such as MGM China. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets. All intercompany balances and transactions are eliminated in consolidation. The Company’s investments in unconsolidated affiliates are accounted for under the equity method when the Company can exercise significant influence over, or has joint control of, the unconsolidated affiliate, such as CityCenter and MGP BREIT Venture. The Company evaluates entities for which control is achieved through means other than voting rights to determine if it is the primary beneficiary of a VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. Management has determined that MGP is a VIE because the Class A equity investors as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded MGP’s ownership interest in the Operating Partnership as noncontrolling interest in the Company’s consolidated financial statements. As of March 31, 2020, on a consolidated basis MGP had total assets of $11.9 billion, primarily related to its real estate investments, and total liabilities of $4.8 billion, primarily related to its indebtedness. Management has determined that Bellagio BREIT Venture is a VIE because the equity holders as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is not the primary beneficiary of Bellagio BREIT Venture and, accordingly, does not consolidate the venture, because the Company does not have power to direct the activities that could potentially be significant to the venture; BREIT, as the managing member, has such power. The Company has recorded its 5% ownership interest in Bellagio BREIT Venture as an investment in unconsolidated affiliates in the Company’s consolidated financial statements, for which such amount was $61 million as of March 31, 2020. The Company’s maximum exposure to loss as a result of its involvement with Bellagio BREIT Venture is equal to the carrying value of its investment, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, as further discussed in Note 7. Reclassifications. Certain reclassifications have been made to conform the prior period presentation. Revenue recognition. The Company’s revenue from contracts with customers consists of casino wagers transactions, hotel room sales, food and beverage transactions, entertainment shows, and retail transactions. For casino wager transactions that include incentives earned by customers under the Company’s loyalty programs, the Company allocates a portion of net win based upon the standalone selling price of such incentive (less estimated breakage). This allocation is deferred and recognized as revenue when the customer redeems the incentive. When redeemed, revenue is recognized in the department that provides the goods or service. Redemption of loyalty incentives at third party outlets are deducted from the loyalty liability and amounts owed are paid to the third party, with any discount received recorded as other revenue. During the three months ended March 31, 2020 and 2019, commissions and incentives provided to gaming customers were $454 million and $602 million, respectively. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue. Contract and Contract-Related Liabilities. There may be a difference between the timing of cash receipts from the customer and the recognition of revenue, resulting in a contract or contract-related liability. The Company generally has three types of liabilities related to contracts with customers: (1) outstanding chip liability, which represents the amounts owed in exchange for gaming chips held by a customer, (2) loyalty program obligations, which represents the deferred allocation of revenue relating to loyalty program incentives earned, as discussed above, and (3) customer advances and other, which is primarily funds deposited by customers before gaming play occurs (“casino front money”) and advance payments on goods and services yet to be provided such as advance ticket sales and deposits on rooms and convention space or for unpaid wagers. These liabilities are generally expected to be recognized as revenue within one year of being purchased, earned, or deposited and are recorded within “Other accrued liabilities” on the Company’s consolidated balance sheets . The following table summarizes the activity related to contract and contract-related liabilities: Outstanding Chip Liability Loyalty Program Customer Advances and Other 2020 2019 2020 2019 2020 2019 (in thousands) Balance at January 1 $ 314,570 $ 323,811 $ 126,966 $ 113,293 $ 481,095 $ 667,285 Balance at March 31 301,333 307,912 128,650 119,033 371,479 613,764 Increase / (decrease) $ (13,237 ) $ (15,899 ) $ 1,684 $ 5,740 $ (109,616 ) $ (53,521 ) Revenue by source. The Company presents the revenue earned disaggregated by the type or nature of the good or service (casino, room, food and beverage, and entertainment, retail and other) and by relevant geographic region within Note 10. Leases. The Company is a lessor under certain of its lease arrangements. Lease revenues earned by the Company from third parties are classified within the line item corresponding to the type or nature of the tenant’s good or service . During the three months ended March 31, 2020 and 2019, lease revenues from third-party tenants include $10 million and $12 million recorded within food and beverage revenue, respectively, and $19 million and $22 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. Lease revenues from the rental of hotel rooms are recorded as rooms revenues within the consolidated statements of operations. Recently issued accounting standards. In June 2016, the FASB issued ASC 326 “Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments” (“ASC 326”), which replaces the existing incurred loss model with a current expected credit loss (CECL) model that requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted ASC 326 on January 1, 2020, which did not have a material impact on its financial statements or accounting policies. The Company now utilizes a forward-looking current expected credit loss model for accounts receivables, guarantees, and other financial instruments. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” (“ASU 2019-12”), which simplifies the accounting for income taxes and includes removal of certain exceptions to the general principles of ASC 740, Income Taxes, and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. ASU 2019-12 is effective for the Company beginning on January 1, 2021. Early adoption is permitted. The Company is currently assessing the impact ASU 2019-12 will have on its consolidated financial statements and footnote disclosures.

Senior credit facility. At March 31, 2020 , the Company’s senior credit facility consisted of a $1.5 billion revolving facility . At March 31, 2020, $1.5 billion was drawn on the revolving credit facility and the interest rate on the revolving credit facility was 2.93%. On February 14, 2020, in connection with the MGP BREIT Venture Transaction, the Company used proceeds from the transaction to repay and terminate the $1.5 billion outstanding on its existing revolving facility in full and entered into a new unsecured credit agreement, comprised of a $1.5 billion unsecured revolving facility that matures in February 2025. The Company incurred a $4 million loss on early retirement of debt recorded in “Other, net” in the consolidated statements of operations. The Company’s senior credit facility contains customary representations and warranties, events of default and positive and negative covenants. The Company was in compliance with its applicable covenants at March 31, 2020. In April 2020, the Company amended its credit facility to provide it with certain relief from the effects of the COVID-19 pandemic. The amendment provides the Company a waiver of the financial maintenance covenants for the period beginning with the quarter ending June 30, 2020 through the earlier of (x) the date the Company delivers to the administrative agent a compliance certificate with respect to the quarter ending June 30, 2021 and (y) the date the Company delivers to the administrative agent an irrevocable notice terminating the covenant relief period (such period, the “covenant relief period”). In connection with the amendment, the Company pledged the Operating Partnership units held by loan parties under the credit agreement to the lenders as collateral. The Company also agreed to certain limitations including, among other things, further restricting its ability to incur debt and liens, make restricted payments, make investments and prepay subordinated debt. In addition, in connection with the amendment, the Company agreed to a liquidity test that requires the Company’s borrower group (as defined in the credit agreement) to maintain a minimum liquidity level of not less than $600 million (including unrestricted cash, cash equivalents and availability under the revolving credit facility), tested at the end of each month during the covenant relief period. Operating Partnership senior credit facility and bridge facility. At March 31, 2020, the Operating Partnership senior credit facility consisted of a $1.35 billion revolving credit facility. In February 2020, in connection with the MGP BREIT Venture Transaction, the Operating Partnership amended its senior secured credit facility to, among other things, allow for the transaction to occur, permit the incurrence by the Operating Partnership of a nonrecourse guarantee for debt of the MGP BREIT Venture, and permit incurrence of a bridge loan facility. As a result of the transaction and the amendment, the Operating Partnership repaid its $1.3 billion outstanding term loan B facility in full with the proceeds of a bridge facility, which was then assumed by the MGP BREIT Venture as partial consideration for the Operating Partnership’s contribution. Additionally, the Operating Partnership used the proceeds from the settlement of the forward equity issuances to pay off all $399 million outstanding on the term loan A facility in full. The Company incurred an $18 million loss on early retirement of debt recorded in “Other, net” in the consolidated statements of operations. At March 31, 2020, $1.35 billion was drawn on the revolving credit facility and the interest rate on the revolving credit facility was 3.19%.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 5 — INCOME TAXES For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate was 28.0% and 51.9% for the three months ended March 31, 2020 and 2019 respectively. The Company recognizes deferred income tax assets, net of applicable reserves, related to net operating losses, tax credit carryforwards and certain temporary differences. The Company recognizes future tax benefits to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. Due to the impact of COVID-19 on its business operations, the Company increased its valuation allowances for Macau deferred tax assets and its foreign tax credits (“FTCs”) by $25 million and $13 million, respectively, with a corresponding increase to provision for income taxes for the quarter ended March 31, 2020. In addition, the Company recorded an income tax benefit of $6 million resulting from recently issued guidance related to deductions for employee dining facilities and income tax expense of $349 million related to the MGP BREIT Venture Transaction that closed on February 14, 2020. The Company's FTCs are attributable to the Macau Special Gaming Tax, which is 35% of gross gaming revenue in Macau. Significant judgment is required in assessing the need for a valuation allowance and future changes to assumptions used in this assessment could result in material changes in the valuation allowance with a corresponding impact on the provision for income taxes in the period including such change. On March 30, 2020, MGM Grand Paradise was granted an extension of its exemption from the Macau 12% complementary tax on gaming profits through June 26, 2022, concurrent with the end of the term of its gaming subconcession. The prior exemption was set to expire on March 31, 2020. The Company previously re-measured its net deferred tax liability for MGM Grand Paradise during 2019 assuming it would receive the complementary tax exemption extension through June 26, 2022 as a result of required non-discriminatory treatment among gaming concessionaires and sub-concessionaires under Macanese law. As a result, no additional remeasurement is required for the three months ended March 31, 2020. The Company continues to assume that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond June 26, 2022 and has factored that assumption into the measurement of Macau deferred tax assets and liabilities.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 7 — COMMITMENTS AND CONTINGENCIES October 1 litigation. The Company and/or certain of its subsidiaries were named as defendants in a number of lawsuits related to the October 1, 2017 shooting in Las Vegas. The matters involve in large degree the same legal and factual issues, each case being filed on behalf of individuals who are seeking damages for emotional distress, physical injury, medical expenses, economic damages and/or wrongful death. Lawsuits were first filed in October 2017 and include actions originally filed in the District Court of Clark County, Nevada and in the Superior Court of Los Angeles County, California. In June 2018, the Company removed to federal court all actions that remained pending in California and Nevada state courts. The Company also initiated declaratory relief actions in federal courts in various districts against individuals who had sued or stated an intent to sue. In connection with the mediation of these matters, the Company and law firms representing plaintiffs in the majority of pending matters and purporting to represent substantially all claimants known to the Company (collectively, the “Claimants”) have entered into a settlement agreement (the “Settlement Agreement”) whereby, subject to the satisfaction of certain monetary and non-monetary conditions, the Company’s insurance carriers will deposit funds into a settlement fund covering the plaintiffs and certain other cases that emerged or were filed prior to October 1, 2019. Pursuant to the terms of the Settlement Agreement, the Company expects that the total amount placed in the fund to be between $735 million and $800 million, subject to and depending on obtaining a minimum level of participation with escalators based on greater participation increasing the amount payable up to $800 million in the event of 100% participation by certain categories of claimants, as defined in the Settlement Agreement. The Company has $751 million of insurance coverage available to fund. Following the mediation a few additional lawsuits were filed against the Company and/or certain of its subsidiaries. While it is possible that these lawsuits may be resolved as part of the Settlement Agreement, no assurances can be made that they will be included. Although the Company continues to believe it is not legally responsible for the perpetrator’s criminal acts, in the interest of avoiding protracted litigation and the related impact on the community, the Company believed it was in the best interests of all parties involved to negotiate and enter into the Settlement Agreement. As a result of the foregoing, the Company believes that it is probable a loss will be incurred and, as of March 31, 2020, the Company accrued a liability of $735 million, which represents the low end of the range of probable loss. In addition, the Company recorded an insurance receivable of $735 million, which represents the entire amount of the liability recorded for the settlement of these cases. While the Company intends for substantially all claimants to be covered by the Settlement Agreement, it remains possible that certain claimants may not join the settlement. In addition, no assurances can be given that the significant conditions to the Settlement Agreement will be satisfied by the Claimants . If the conditions in the Settlement Agreement are not satisfied and the mediation stay is lifted, the Company is currently unable to reliably predict the future developments in, outcome of, and economic costs and other consequences of any such litigation related to this matter. The Company will continue to investigate the factual and legal defenses, and evaluate these matters based on subsequent events, new information and future circumstances. The Company intends to defend against any such lawsuits and believes it ultimately should prevail, but litigation of this type is inherently unpredictable. Although there are significant procedural, factual and legal issues to be resolved that could significantly affect the Company’s belief as to the possibility of liability, the Company currently believes that it is reasonably possible that it could incur liability in connection with certain of these lawsuits. The foregoing determination was made in accordance with generally accepted accounting principles, as codified in ASC 450-20, and is not an admission of any liability on the part of the Company or any of its affiliates. Given that these cases would be in the early stages, and in light of the uncertainties surrounding them, the Company does not currently possess sufficient information to determine a range of reasonably possible liability. The insurance carriers have not expressed a reservation of rights or coverage defense that affects the Company’s evaluation of potential losses in connection with these claims. The Company’s general liability insurance coverage provides, as part of the contractual “duty to defend”, payment of legal fees and associated costs incurred to defend covered lawsuits that are filed arising from the October 1, 2017 shooting in Las Vegas. Payment of such fees and costs is in addition to (and not limited by) the limits of the insurance policies and does not erode the total liability coverage available. Other litigation. The Company is a party to various legal proceedings, most of which relate to routine matters incidental to its business. Management does not believe that the outcome of such proceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows . Other guarantees. The Company and its subsidiaries are party to various guarantee contracts in the normal course of business, which are generally supported by letters of credit issued by financial institutions . The Company’s senior credit facility limits the amount of letters of credit that can be issued to $500 million as of March 31, 2020 and such limit was increased to $850 million in connection with the amendment to the credit facility discussed in Note 4. At March 31, 2020, $11 million in letters of credit were outstanding under the Company’s senior credit facility. The Operating Partnership’s senior credit facility limits the amount to $75 million. No letters of credit were outstanding under the Operating Partnership’s senior credit facility at March 31, 2020. The amount of available borrowings under each of the credit facilities is reduced by any outstanding letters of credit. MGM China guarantee. In connection with the extension of the expiration of the gaming subconcession to June 2022, MGM Grand Paradise provided a bank guarantee in an amount of approximately $103 million (when giving effect to foreign currency exchange rate fluctuations) to the government of Macau in May 2019 to warrant the fulfillment of an existing commitment of labor liabilities upon the expiration of the gaming subconcession in June 2022. Bellagio BREIT Venture guarantee. The Company provides a shortfall guarantee of the $3.01 billion principal amount of indebtedness (and any interest accrued and unpaid thereon) of Bellagio BREIT Venture, which matures in 2029. The terms of the shortfall guarantee provide that after the lenders have exhausted certain remedies to collect on the obligations under the indebtedness, the Company would then be responsible for any shortfall between the value of the collateral, which is the real estate assets of Bellagio owned by Bellagio BREIT Venture, and the debt obligation. This guarantee is accounted for under ASC 460 at fair value; such value is immaterial. MGP BREIT Venture guarantee. The Company provides a shortfall guarantee of the $3.0 billion principal amount of indebtedness (and any interest accrued and unpaid thereon) of MGP BREIT Venture, which has an initial term of twelve years, maturing in 2032, with an anticipated repayment date of March 2030. The terms of the shortfall guarantee provide that after the lenders have exhausted certain remedies to collect on the obligations under the indebtedness, the Company would then be responsible for any shortfall between the value of the collateral, which is the real estate assets of Mandalay Bay and MGM Grand Las Vegas, owned by MGP BREIT Venture, and the debt obligation. This guarantee is accounted for under ASC 460 at fair value; such value is immaterial. The Operating Partnership provides a guarantee for the losses incurred by the lenders of the indebtedness of the MGP BREIT Venture arising out of certain bad acts by the Operating Partnership, its venture partner, or the venture, such as fraud or willful misconduct, based on the party’s percentage ownership of the MGP BREIT Venture. This guarantee is capped at 10% of the principal amount outstanding at the time of the loss. The Operating Partnership and its venture partner have separately indemnified each other for the other party’s share of the overall liability exposure, if at fault. The guarantee is accounted for under ASC 460 at fair value; such value is immaterial.

Segment Reporting [Abstract]
Segment Information	NOTE 10 — SEGMENT INFORMATION The Company’s management views each of its casino resorts as an operating segment. Operating segments are aggregated based on their similar economic characteristics, types of customers, types of services and products provided, the regulatory environments in which they operate and their management and reporting structure. The Company has aggregated its operating segments into the following reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. Las Vegas Strip Resorts . Las Vegas Strip Resorts consists of the following casino resorts: Bellagio, MGM Grand Las Vegas (including The Signature), Mandalay Bay (including Delano and Four Seasons), The Mirage, Luxor, New York-New York (including the Park), Excalibur, Park MGM (including NoMad Las Vegas) and Circus Circus Las Vegas (until the sale of such property in December 2019) . Regional Operations. Regional Operations consists of the following casino resorts: MGM Grand Detroit in Detroit, Michigan; Beau Rivage in Biloxi, Mississippi; Gold Strike Tunica in Tunica, Mississippi; Borgata in Atlantic City, New Jersey; MGM National Harbor in Prince George’s County, Maryland; MGM Springfield in Springfield, Massachusetts; Empire City in Yonkers, New York (upon acquisition in January 2019); and MGM Northfield Park in Northfield Park, Ohio (upon MGM’s acquisition of the operations from MGP in April 2019). MGM China. MGM China consists of MGM Macau and MGM Cotai. The Company’s operations related to investments in unconsolidated affiliates, MGM Northfield Park (prior to April 1, 2019 as the operations were owned by MGP until that date), and certain other corporate operations and management services have not been identified as separate reportable segments; therefore, these operations are included in “Corporate and other” in the following segment disclosures to reconcile to consolidated results. The Company’s management utilizes Adjusted Property EBITDAR as the primary profit measure for its reportable segments and underlying operating segments. Adjusted Property EBITDAR is a measure defined as Adjusted EBITDAR before corporate expense and stock compensation expense, which are not allocated to each operating segment, and before rent expense related to the master lease with MGP that eliminates in consolidation. Adjusted EBITDAR is a measure defined as earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses, gain on REIT transactions, net, CEO transition expense, restructuring costs (which represents costs related to severance, accelerated stock compensation expense, and consulting fees directly related to the operating model component of the MGM 2020 Plan), rent expense associated with triple net operating and ground leases, income from unconsolidated affiliates related to investments in REITs, and property transactions, net.

The annual rent payments under the MGP master lease for the fifth lease year, which commenced on April 1, 2020, increased to $828 million from $813 million, as a result of the fourth 2.0% fixed annual rent escalator that went into effect on April 1, 2020. All intercompany transactions, including transactions under the MGP master lease, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares is recognized as non-controlling interests in the Company’s consolidated financial statements.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission (“SEC”), certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2019 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year.
Principles of consolidation	Principles of consolidation. For entities not determined to be a variable interest entity (“VIE”), the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity if it has the direct or indirect ability to control the entities’ activities based upon the terms of the respective entities’ ownership agreements, such as MGM China. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets. All intercompany balances and transactions are eliminated in consolidation. The Company’s investments in unconsolidated affiliates are accounted for under the equity method when the Company can exercise significant influence over, or has joint control of, the unconsolidated affiliate, such as CityCenter and MGP BREIT Venture. The Company evaluates entities for which control is achieved through means other than voting rights to determine if it is the primary beneficiary of a VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. Management has determined that MGP is a VIE because the Class A equity investors as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded MGP’s ownership interest in the Operating Partnership as noncontrolling interest in the Company’s consolidated financial statements. As of March 31, 2020, on a consolidated basis MGP had total assets of $11.9 billion, primarily related to its real estate investments, and total liabilities of $4.8 billion, primarily related to its indebtedness. Management has determined that Bellagio BREIT Venture is a VIE because the equity holders as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is not the primary beneficiary of Bellagio BREIT Venture and, accordingly, does not consolidate the venture, because the Company does not have power to direct the activities that could potentially be significant to the venture; BREIT, as the managing member, has such power. The Company has recorded its 5% ownership interest in Bellagio BREIT Venture as an investment in unconsolidated affiliates in the Company’s consolidated financial statements, for which such amount was $61 million as of March 31, 2020. The Company’s maximum exposure to loss as a result of its involvement with Bellagio BREIT Venture is equal to the carrying value of its investment, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, as further discussed in Note 7.
Reclassifications	Reclassifications. Certain reclassifications have been made to conform the prior period presentation.
Revenue recognition	Revenue recognition. The Company’s revenue from contracts with customers consists of casino wagers transactions, hotel room sales, food and beverage transactions, entertainment shows, and retail transactions. For casino wager transactions that include incentives earned by customers under the Company’s loyalty programs, the Company allocates a portion of net win based upon the standalone selling price of such incentive (less estimated breakage). This allocation is deferred and recognized as revenue when the customer redeems the incentive. When redeemed, revenue is recognized in the department that provides the goods or service. Redemption of loyalty incentives at third party outlets are deducted from the loyalty liability and amounts owed are paid to the third party, with any discount received recorded as other revenue. During the three months ended March 31, 2020 and 2019, commissions and incentives provided to gaming customers were $454 million and $602 million, respectively. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue. Contract and Contract-Related Liabilities. There may be a difference between the timing of cash receipts from the customer and the recognition of revenue, resulting in a contract or contract-related liability. The Company generally has three types of liabilities related to contracts with customers: (1) outstanding chip liability, which represents the amounts owed in exchange for gaming chips held by a customer, (2) loyalty program obligations, which represents the deferred allocation of revenue relating to loyalty program incentives earned, as discussed above, and (3) customer advances and other, which is primarily funds deposited by customers before gaming play occurs (“casino front money”) and advance payments on goods and services yet to be provided such as advance ticket sales and deposits on rooms and convention space or for unpaid wagers. These liabilities are generally expected to be recognized as revenue within one year of being purchased, earned, or deposited and are recorded within “Other accrued liabilities” on the Company’s consolidated balance sheets . The following table summarizes the activity related to contract and contract-related liabilities: Outstanding Chip Liability Loyalty Program Customer Advances and Other 2020 2019 2020 2019 2020 2019 (in thousands) Balance at January 1 $ 314,570 $ 323,811 $ 126,966 $ 113,293 $ 481,095 $ 667,285 Balance at March 31 301,333 307,912 128,650 119,033 371,479 613,764 Increase / (decrease) $ (13,237 ) $ (15,899 ) $ 1,684 $ 5,740 $ (109,616 ) $ (53,521 ) Revenue by source. The Company presents the revenue earned disaggregated by the type or nature of the good or service (casino, room, food and beverage, and entertainment, retail and other) and by relevant geographic region within Note 10. Leases. The Company is a lessor under certain of its lease arrangements. Lease revenues earned by the Company from third parties are classified within the line item corresponding to the type or nature of the tenant’s good or service . During the three months ended March 31, 2020 and 2019, lease revenues from third-party tenants include $10 million and $12 million recorded within food and beverage revenue, respectively, and $19 million and $22 million recorded within entertainment, retail, and other revenue for the same such periods, respectively. Lease revenues from the rental of hotel rooms are recorded as rooms revenues within the consolidated statements of operations.
Recently issued accounting standards	Recently issued accounting standards. In June 2016, the FASB issued ASC 326 “Financial Instruments - Credit Losses (Topic 326): Measurements of Credit Losses on Financial Instruments” (“ASC 326”), which replaces the existing incurred loss model with a current expected credit loss (CECL) model that requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The Company adopted ASC 326 on January 1, 2020, which did not have a material impact on its financial statements or accounting policies. The Company now utilizes a forward-looking current expected credit loss model for accounts receivables, guarantees, and other financial instruments. In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes,” (“ASU 2019-12”), which simplifies the accounting for income taxes and includes removal of certain exceptions to the general principles of ASC 740, Income Taxes, and simplification in several other areas such as accounting for a franchise tax (or similar tax) that is partially based on income. ASU 2019-12 is effective for the Company beginning on January 1, 2021. Early adoption is permitted. The Company is currently assessing the impact ASU 2019-12 will have on its consolidated financial statements and footnote disclosures.
