Additionally, the Company operates The Park, a dining and entertainment district located between New York-New York and Park MGM. The Company leases the real estate assets of its domestic resorts pursuant to triple-net lease agreements, as further discussed in Note 11. 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 MGM Macau and MGM Cotai, two integrated casino, hotel and entertainment resorts in Macau, as well as the related gaming concession and land concessions. The Company also has an approximate 98% controlling interest in LeoVegas AB (“LeoVegas”), a consolidated subsidiary that has global online gaming operations headquartered in Sweden and Malta. Additionally, the Company and its venture partner, Entain plc, each have a 50% ownership interest in BetMGM, LLC (“BetMGM”), an unconsolidated affiliate, which provides online sports betting and gaming in certain jurisdictions in North America. MGP and the VICI Transaction. Prior to the closing of the VICI Transaction (defined below), MGM Growth Properties LLC (“MGP”) was a consolidated subsidiary of the Company. Substantially all of its assets were owned by and substantially all of its operations were conducted through MGM Growth Properties Operating Partnership LP (“MGP OP”). MGP had two classes of common shares: Class A shares and a single Class B share. The Company owned MGP’s Class B share, through which it held a controlling interest in MGP as it was entitled to an amount of votes representing a majority of the total voting power of MGP’s shares. The Company and MGP each held MGP OP units representing limited partner interests in MGP OP. Immediately prior to the VICI Transaction, the Company owned 41.5% of MGP OP units, and MGP held the remaining 58.5% ownership interest in MGP OP. Additionally, the Company had leased the real estate assets of certain of its domestic properties from MGP OP, as further discussed in Note 18, and the real estate assets of Mandalay Bay and MGM Grand Las Vegas from a venture that was 50.1% owned by a subsidiary of MGP OP and 49.9% by a subsidiary of Blackstone Real Estate Investment Trust, Inc. (“BREIT”, such venture, the “VICI BREIT Venture”). On April 29, 2022, the Company completed a series of transactions with VICI Properties, Inc. (“VICI”) and MGP whereby VICI acquired MGP in a stock-for-stock transaction (such transaction, the “VICI Transaction”), with the Company retaining an approximate 1% ownership interest in VICI Properties OP LLC (“VICI OP”). MGP’s Class B share that was held by the Company was cancelled. Accordingly, the Company no longer holds a controlling interest in MGP and deconsolidated MGP upon the closing of the transactions. Refer to Note 4 for further discussion of the transactions. In connection with the VICI Transaction, the Company entered into an amended and restated master lease with VICI. Refer to Note 11 for further discussion of the lease. The Cosmopolitan acquisition. On May 17, 2022, the Company acquired the operations of The Cosmopolitan. Additionally, the Company entered into a lease agreement for the real estate assets of The Cosmopolitan. Refer to Note 4 for additional information on this acquisition and Note 11 for further discussion of the lease. LeoVegas acquisition. On September 7, 2022, the Company acquired LeoVegas. Refer to Note 4 for additional information on this acquisition. The Mirage transaction. On December 19, 2022, the Company completed the sale of the operations of The Mirage to an affiliate of Seminole Hard Rock Entertainment, Inc. (“Hard Rock”). Refer to Note 4 for additional information on this disposition. Gold Strike Tunica transaction. On February 15, 2023, the Company completed the sale of the operations of Gold Strike Tunica to CNE Gaming Holdings, LLC (“CNE”), a subsidiary of Cherokee Nation Business. Refer to Note 4 for additional information on this disposition. CityCenter acquisition. On September 27, 2021, the Company acquired the 50% ownership interest in CityCenter Holdings, LLC (“CityCenter”) held by Infinity World Development Corp (“Infinity World”), a wholly owned subsidiary of Dubai World, a Dubai, United Arab Emirates government decree entity. CityCenter is located between Bellagio and Park MGM and consists of Aria, an integrated casino, hotel and entertainment resort; and Vdara, a luxury condominium-hotel. Refer to Note 4 for additional information on this acquisition. On September 28, 2021, the Company sold the real estate assets of Aria (including Vdara) to funds managed by The Blackstone Group Inc. (“Blackstone”) for cash consideration of $3.89 billion and entered into a lease through which the real property is leased back to a subsidiary of the Company, as further discussed in Note 11. MGM Grand Las Vegas and Mandalay Bay transaction. On February 14, 2020, the Company completed a series of transactions (collectively the “MGM Grand Las Vegas and Mandalay Bay transaction”) pursuant to which the real estate assets of MGM Grand Las Vegas and Mandalay Bay (including Mandalay Place) were contributed to the newly formed VICI BREIT Venture. 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 MGP OP’s secured indebtedness assumed by VICI BREIT Venture, and MGP OP’s 50.1% equity interest in VICI BREIT Venture. In addition, MGP OP issued approximately 3 million MGP OP units to the Company representing 5% of the equity value of VICI BREIT Venture. The Company recorded the difference between consideration received of $2.5 billion and the carrying value of the MGM Grand Las Vegas 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 $10 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 provides a shortfall guarantee of the principal amount of indebtedness of VICI BREIT Venture (and any interest accrued and unpaid thereon) as further discussed in Note 12. On the closing date, BREIT also purchased approximately 5 million MGP Class A shares for $150 million . In connection with the MGM Grand Las Vegas and Mandalay Bay transaction, the master lease with MGP was modified to remove the Mandalay Bay property and VICI 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. Refer to Note 11 for a discussion of the lease. MGM Grand Paradise gaming subconcession and gaming concession. Gaming in Macau is currently administered by the Macau Government through concessions awarded to six different concessionaires. Pursuant to the agreement dated April 19, 2005 between MGM Grand Paradise and SJM Resorts S.A. (formerly Sociedade de Jogos de Macau, S.A.), a gaming subconcession was acquired by MGM Grand Paradise for the right to operate casino games of chance and other casino games for a period commencing on April 20, 2005 through March 31, 2020. Pursuant to the then-existing Macau gaming law, upon reaching the maximum duration foreseen in the law (up to a maximum term of 20 years), the term of the concessions may be extended one or more times by order of the Chief Executive, which period may not exceed, in total, 5 years. In 2019, MGM Grand Paradise’s subconcession term was extended from March 31, 2020 to June 26, 2022, consistent with the expiration of the other concessionaires and subconcessionaires. On June 23, 2022, MGM Grand Paradise entered into an addendum to its subconcession pursuant to which its gaming subconcession was extended to December 31, 2022 (refer to Note 7 for additional considerations relating to the gaming subconcession). In connection with the extension, MGM Grand Paradise paid the Macau government MOP 47 million (approximately $6 million). On January 14, 2022, the Macau government disclosed the content of a proposed bill to amend Macau gaming law, which followed a 45-day public consultation process regarding draft amendment proposals that were issued in September 2021. The new gaming law was approved by the Macau Legislative Assembly on June 21, 2022 and published in the Macau Official Gazette on June 22, 2022. Under the new gaming law, the existing subconcessions were discontinued and a maximum of six concessions were to be awarded for a term to be specified in the concession contract that may not exceed 10 years and which may be extended by three years under certain exceptional circumstances. The enactment of the new gaming law preceded the public tender for the awarding of new gaming concessions for which the rules of the public tender were published on July 1, 2022, which outlined the details for the bidding, the qualifications of bidding companies, and the criteria for granting the new gaming concessions. On December 16, 2022, MGM Grand Paradise was awarded a concession contract to permit the operation of games of chance or other games in casinos in Macau for a period of ten years, commencing on January 1, 2023. Reportable segments. The Company has three reportable segments: Las Vegas Strip Resorts, Regional Operations and MGM China. See Note 17 for additional information about the Company’s segments. Impact of COVID-19. The spread of the novel 2019 coronavirus (“COVID-19”) and developments surrounding the global pandemic have had a significant impact on the Company’s business, financial condition, results of operations and cash flows in 2020, 2021 and 2022 and may continue to impact the Company's business thereafter. In March 2020, all of the Company’s domestic properties were temporarily closed pursuant to state and local government restrictions imposed as a result of COVID-19. Throughout the second and third quarters of 2020, all of the Company’s properties that were temporarily closed re-opened to the public, with temporary re-closures and re-openings occurring for certain of the Company’s properties or portions thereof into the first quarter of 2021. Upon re-opening, the properties continued to operate without certain amenities and subject to certain occupancy limitations, with restrictions varying by jurisdiction. Beginning in the latter part of the first quarter of 2021 and continuing into the second quarter of 2021, the Company’s domestic jurisdictions eased and removed prior operating restrictions, including capacity and occupancy limits, as well as social distancing policies. As of December 31, 2022, all of the Company’s domestic properties were open and not subject to operating restrictions; however, travel and business volume were negatively affected in the early part of the first quarter of 2022 due to the spread of the omicron variant. In Macau, following a temporary closure of the Company’s properties on February 5, 2020, operations resumed on February 20, 2020, subject to certain health safeguards, such as limiting the number of seats available at each table game, slot machine spacing, reduced operating hours at a number of restaurants and bars, temperature checks, and mask protection. The issuance of tourist visas (including the individual visit scheme) for residents of Zhuhai, Guangdong Province and all other provinces in mainland China to travel to Macau resumed on August 12, 2020, August 26, 2020 and September 23, 2020, respectively, however several travel and entry restrictions in Macau, Hong Kong and mainland China remained in place (including the temporary suspension of ferry services between Hong Kong and Macau, the negative nucleic acid test result certificate, and mandatory quarantine requirements for returning residents, for visitors from Hong Kong, Taiwan, and certain regions in mainland China, and bans on entry on other visitors), which significantly impacted visitation to the Company’s Macau properties. In the third and fourth quarters of 2021, local COVID-19 cases were identified in Macau. Upon such occurrences, a state of immediate prevention was declared and mass mandatory nucleic acid testing was imposed in Macau, the validity period of negative test results for re-entry into mainland China was shortened and quarantine requirements were imposed, certain events were cancelled or suspended, and in some instances, certain entertainment and leisure facilities were closed throughout Macau. Gaming operations were temporarily suspended on July 11, 2022 due to an increase in the number of COVID-19 cases in Macau and resumed on July 23, 2022, subject to certain continuing health safeguards, with most restaurants and bars and certain retail outlets remained closed. On October 30, 2022, a COVID-19 case was identified as connected to MGM Cotai. All guests and staff at MGM Cotai were isolated until November 1, 2022 and all gaming, hotel, restaurant, and retail operations were suspended with limited operations resumed beginning November 3, 2022. More broadly, electronic applications for individual and group travel visas to Macau resumed on November 1, 2022, however, certain travel and entry restrictions in Macau and mainland China remained in place at the time, including COVID-19 testing and certain quarantine requirements, which significantly impacted visitation to the Company’s Macau properties. Beginning in December 2022, Macau and mainland China started to unwind testing and quarantine requirements as well as travel and entry restrictions associated with the “dynamic zero” COVID-19 policy. On January 8, 2023, Macau lifted the majority of its COVID-19 pandemic travel and quarantine restrictions with the exception of overseas visitors travelling from outside of mainland China, Hong Kong and Taiwan being required to present a negative nucleic acid test or rapid antigen test result in place until February 6, 2023 when all remaining COVID-19 travel restrictions were removed.

Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES	BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Principles of consolidation. 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 variable interest entity (“VIE”). The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. 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 . The venture (the “Bellagio BREIT Venture”) that is 5% owned by a subsidiary of the Company and 95% owned by a subsidiary of BREIT 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 is not the primary beneficiary of Bellagio BREIT Venture because the Company does not have power to direct the activities that could potentially be significant to the venture as BREIT, as the managing member, has such power; accordingly, the Company does not consolidate the venture. The Company’s maximum exposure to loss in Bellagio BREIT Venture is equal to the carrying value of its investment of $56 million as of December 31, 2022, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, which guarantee is immaterial as of December 31, 2022, as further discussed in Note 12. For entities determined not to be a 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 under the voting interest model if it has a controlling financial interest 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 and all intercompany balances and transactions are eliminated in consolidation. If the entity does not qualify for consolidation under the voting interest model and the Company has significant influence over the operating and financial decisions of the entity, the Company generally accounts for the entity under the equity method, such as BetMGM, which does not qualify for consolidation as the Company has joint control, given the entity is structured with substantive participating rights whereby both owners participate in the decision making process, which prevents the Company from exerting a controlling financial interest in such entity, as defined in ASC 810. For entities over which the Company does not have significant influence, such as VICI OP, the Company accounts for its equity investment under ASC 321. Reclassifications . Certain reclassifications have been made to conform the prior period presentation. Management’s use of estimates. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. These principles require the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates or equity interests, assets acquired, and liabilities assumed in an acquisition, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are quoted prices for identical or comparable instruments or pricing using observable market data; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 inputs when measuring its equity investments recorded at fair value; • Level 2 inputs for its long-term debt fair value disclosures. See Note 9; • Level 1 and Level 2 inputs for its debt investments; and • Level 1, Level 2, and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed in acquisitions. See Note 4. Equity investments. Fair value is measured based upon trading prices on the applicable securities exchange for equity investments for which the Company has elected the fair value option of Accounting Standards Codification (“ASC”) 825, such as LeoVegas (prior to consolidation), and equity investments accounted for under ASC 321 that have a readily determinable fair value, such as VICI OP. The fair value of these investments was $461 million and $66 million as of December 31, 2022 and 2021, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Gains and losses are recorded in “Other, net” in the statements of operations. For the years ended December 31, 2022, and 2021 the Company recorded a net gain on its equity investments of $10 million and $28 million, respectively. Debt investments. The Company’s investments in debt securities are classified as trading securities and recorded at fair value. Gains and losses are recorded in “Other, net” in the statement of operations. Debt securities are considered cash equivalents if the criteria for such classification is met or otherwise classified as short-term investments within “Prepaid expenses and other” since the investment of cash is available for current operations. The following tables present information regarding the Company’s debt investments: Fair value level December 31, 2022 (In thousands) Cash and cash equivalents: Money market funds Level 1 $ 12,009 Commercial paper and certificates of deposit Level 2 5,992 Cash and cash equivalents 18,001 Short-term investments: U.S. government securities Level 1 56,835 U.S. agency securities Level 2 9,530 Commercial paper and certificates of deposit Level 2 4,466 Corporate bonds Level 2 213,875 Short-term investments 284,706 Total debt investments $ 302,707 Cash and cash equivalents. Cash and cash equivalents include cash on hand, investments and interest-bearing instruments that are highly liquid with maturities of 90 days or less at the date of acquisition. Book overdraft balances resulting from the Company’s cash management program are recorded within “Accounts and construction payable.” Restricted cash. Cash held in an escrow account related to the reverse termination fee that was contractually required to be prefunded for The Cosmopolitan acquisition was reflected as “Restricted Cash” on the consolidated balance sheets as of December 31, 2021. “Restricted Cash” and “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of December 31, 2021. MGM China’s pledged cash of $124 million securing the bank guarantees discussed in Note 12 is restricted in use and classified within “Other long-term assets, net.” Such amount plus “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of December 31, 2022. Accounts receivable and credit risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of casino receivables. The Company issues credit following background checks and investigations of creditworthiness. At December 31, 2022 and 2021, approximately 52% and 53%, respectively, of the Company’s gross accounts receivable related to casino receivables. Accounts receivable are typically non-interest bearing and are initially recorded at cost. Accounts are written off when management deems the account to be uncollectible. Recoveries of accounts previously written off are recorded when received. An estimated loss reserve is maintained to reduce the Company’s receivables to their net carrying amount, which approximates fair value. The loss reserve is estimated based on both a specific review of customer accounts as well as historical collection experience and current and expected future economic and business conditions. Management believes that as of December 31, 2022, no significant concentrations of credit risk existed for which a loss reserve had not already been recorded. Inventories. Inventories consist primarily of food and beverage, retail merchandise and operating supplies, and are stated at the lower of cost or net realizable value. Cost is determined primarily using the average cost method for food and beverage and operating supplies. Cost for retail merchandise is determined using the cost method. Property and equipment. Property and equipment are stated at cost. A significant amount of the Company’s property and equipment was acquired through business combinations and therefore recognized at fair value at the acquisition date. Gains or losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. Property and equipment are generally depreciated over the following estimated useful lives on a straight-line basis: Buildings and improvements 15 to 40 years Land improvements 10 to 20 years Furniture and fixtures 3 to 20 years Equipment 3 to 15 years The Company evaluates its property and equipment and other long-lived assets for impairment based on its classification as held for sale or to be held and used. Several criteria must be met before an asset is classified as held for sale, including that management with the appropriate authority commits to a plan to sell the asset at a reasonable price in relation to its fair value and is actively seeking a buyer. For assets held for sale, the Company recognizes the asset at the lower of carrying value or fair market value less costs to sell, as estimated based on comparable asset sales, offers received, or a discounted cash flow model. For assets to be held and used, the Company reviews for impairment whenever indicators of impairment exist. The Company then compares the estimated future cash flows of the asset group, on an undiscounted basis, to the carrying value of the asset group. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset, typically measured using a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs. All recognized impairment losses, whether for assets held for sale or assets to be held and used, are recorded as operating expenses. In connection with the expiration of the MGM Grand Paradise gaming subconcession on December 31, 2022, the casino areas of MGM Cotai and MGM Macau reverted, free of charge and without any encumbrances, to the Macau government, which is now the legal owner of the reverted gaming assets. On January 1, 2023 and in connection with the commencement of the gaming concession, the gaming assets were temporarily transferred to MGM Grand Paradise for the duration of the gaming concession in return for annual payments. As the Company will continue to operate the gaming assets in the same manner as under the gaming subconcession, obtain substantially all of the economic benefits, and bear all of the risks arising from the use of assets for the economic life of the assets as the Company assumes it will be successful in the awarding of a new concession at the end of the current term, the Company will continue to recognize the reverted gaming assets within “Property and equipment” and depreciate the assets over their remaining estimated useful lives. Capitalized interest. The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. When no debt is incurred specifically for a project, interest is capitalized on amounts expended on the project using the weighted average cost of the Company’s outstanding borrowings. Capitalization of interest ceases when the project is substantially complete, or development activity is suspended for more than a brief period. Investments in and advances to unconsolidated affiliates. The Company has investments in unconsolidated affiliates accounted for under the equity method. Under the equity method, carrying value is adjusted for the Company’s share of the investees’ earnings and losses, amortization of certain basis differences, as well as capital contributions to and distributions from these companies. Distributions in excess of equity method earnings are recognized as a return of investment and recorded as investing cash inflows in the accompanying consolidated statements of cash flows. The Company classifies operating income and losses as well as gains and impairments related to its investments in unconsolidated affiliates as a component of operating income or loss and classifies non-operating income or losses related to its investments in unconsolidated affiliates as a component of non-operating income or loss, as the Company’s investments in such unconsolidated affiliates are an extension of the Company’s core business operations. The Company evaluates its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying value of its investment may have experienced an other-than-temporary decline in value. If such conditions exist, the Company compares the estimated fair value of the investment to its carrying value to determine if an impairment is indicated and determines whether the impairment is “other-than-temporary” based on its assessment of all relevant factors, including consideration of the Company’s intent and ability to retain its investment. The Company estimates fair value using a discounted cash flow analysis based on estimated future results of the investee and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. Goodwill and other intangible assets. Goodwill represents the excess of purchase price over fair market value of net assets acquired in business combinations. Indefinite-lived intangibles consist of trademarks and certain of our gaming licenses. Goodwill and indefinite-lived intangible assets must be reviewed for impairment at least annually and between annual test dates in certain circumstances. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. No material impairments were indicated or recorded as a result of the annual impairment review for goodwill and indefinite-lived intangible assets in 2022, 2021, and 2020. Accounting guidance provides entities the option to perform a qualitative assessment of goodwill and indefinite-lived intangible assets (commonly referred to as “step zero”) in order to determine whether further impairment testing is necessary. In performing the step zero analysis the Company considers macroeconomic conditions, industry and market considerations, current and forecasted financial performance, entity-specific events, and changes in the composition or carrying amount of net assets of reporting units for goodwill. In addition, the Company takes into consideration the amount of excess of fair value over carrying value determined in the last quantitative analysis that was performed, as well as the period of time that has passed since the last quantitative analysis. If the step zero analysis indicates that it is more likely than not that the fair value is less than its carrying amount, the entity would proceed to a quantitative analysis. Under the quantitative analysis, goodwill for relevant reporting units is tested for impairment using a discounted cash flow analysis based on the estimated future results of the Company’s reporting units discounted using market discount rates and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. If the fair value of the reporting unit is less than its carrying value, an impairment charge is recognized equal to the difference. Under the quantitative analysis, license rights are tested for impairment using a discounted cash flow approach, and trademarks are tested for impairment using the relief-from-royalty method. If the fair value of an indefinite-lived intangible asset is less than its carrying amount, an impairment loss is recognized equal to the difference. Other intangible assets that have a finite life, including MGM Grand Paradise’s gaming subconcession, other gaming rights in certain jurisdictions where the nature or extent of the renewal process is uncertain, customer lists, and technology, are amortized on a straight-line basis over their estimated useful lives. The Company reviews the carrying amount of its amortizing intangible assets for possible impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. When testing for impairment, the Company compares the estimated undiscounted cash flows of the asset group to its carrying value. If the estimated undiscounted cash flows exceed the carrying value, no impairments are recorded. If the undiscounted cash flows do not exceed the carrying values, an impairment is recorded. Note receivable. In connection with the sale of Circus Circus Las Vegas and the adjacent land in December 2019, the Company received a secured note due in 2024 with a face value of $163 million and fair value of $134 million. The note has a stated interest rate of 3% for the first two years, 4% for following two years, and 4.5% for the fifth year and is secured by the borrower with the land adjacent to Circus Circus Las Vegas as collateral with an effective interest rate of 7.31%. The interest on the note, which is comprised of the stated interest and the discount on the note, amortizes into interest income using the effective interest method over the length of the agreement. The carrying value of the note receivable was $167 million and $155 million as of December 31, 2022 and 2021, respectively, and was recorded within “Other long-term assets, net” in the consolidated balance sheets. Accounts payable. As of December 31, 2022 and 2021, the Company had accrued $80 million and $59 million, respectively, for purchases of property and equipment within “Accounts and construction payable” on the consolidated balance sheets. 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. The transaction price for a casino wager is the difference between gaming wins and losses (“net win”). In certain circumstances, the Company offers discounts on markers, which is estimated based upon historical business practice, and recorded as a reduction of casino revenue. Commissions rebated to gaming promoters and VIP players at MGM China are also recorded as a reduction of casino revenue. The Company accounts for casino revenue on a portfolio basis given the similar characteristics of wagers by recognizing net win per gaming day versus on an individual wager basis. For casino wager transactions that include other goods and services provided by the Company to gaming patrons on a discretionary basis to incentivize gaming, the Company allocates revenue from the casino wager transaction to the good or service delivered based upon standalone selling price (“SSP”). Discretionary goods and services provided by the Company and supplied by third parties are recognized as an operating expense. 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 SSP 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. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue . The transaction price of rooms, food and beverage, and retail contracts is the net amount collected from the customer for such goods and services. The transaction price for such contracts is recorded as revenue when the good or service is transferred to the customer over their stay at the hotel or when the delivery is made for the food & beverage and retail & other contracts. Sales and usage-based taxes are excluded from revenues. For some arrangements, the Company acts as an agent in that it arranges for another party to transfer goods and services and the Company is not the controlling entity, which primarily include certain of the Company’s entertainment shows and, in certain jurisdictions, the Company’s arrangement with BetMGM for online sports betting and iGaming. The Company also has other contracts that include multiple goods and services, such as packages that bundle food, beverage, or entertainment offerings with hotel stays and convention services. For such arrangements, the Company allocates revenue to each good or service based on its relative SSP. The Company primarily determines the SSP of rooms, food and beverage, entertainment, and retail goods and services based on the amount that the Company charges when sold separately in similar circumstances to similar customers. 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, 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 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 2022 2021 2022 2021 2022 2021 (In thousands) Balance at January 1 $ 176,219 $ 212,671 $ 144,465 $ 139,756 $ 640,001 $ 382,287 Balance at December 31 185,669 176,219 183,602 144,465 816,376 640,001 Increase / (decrease) $ 9,450 $ (36,452) $ 39,137 $ 4,709 $ 176,375 $ 257,714 The December 31, 2022 balances exclude liabilities related to assets held for sale. See Note 4. Reimbursed cost. Costs reimbursed pursuant to management services are recognized as revenue in the period it incurs the costs as this reflects when the Company performs its related performance obligation and is entitled to reimbursement. Reimbursed costs related primarily to the Company’s management of CityCenter (such management agreement was terminated upon the acquisition of CityCenter in September 2021). 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 17. Leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period of time in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. The Company classifies a lease with terms greater than twelve months as either operating or finance. At commencement, the right-of-use (“ROU”) assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. The initial measurement of ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, such as for the Company’s triple-net operating leases for which the lessor has provided its implicit rate or provided the assumptions required for the Company to readily determine the rate implicit in the lease, the Company uses the rate implicit in the lease to discount lease payments to present value. However, for most of the Company’s leases, such as its ground subleases and equipment leases, the Company cannot readily determine the implicit rate. Accordingly, the Company uses its incremental borrowing rate to discount the lease payments for such leases based on the information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. The Company’s triple-net operating leases each contain renewal periods at the Company’s option, each of which are not considered to be reasonably certain of being exercised. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. For finance leases, the ROU asset depreciates on a straight-line basis over the shorter of the lease term or useful life of the ROU asset and the lease liability accretes interest based on the interest method using the discount rate determined at lease commencement. Refer to Note 11 for discussion of leases under which the Company is a lessee. Refer to Note 18 for discussion of the master lease with MGP. The Company is a lessor under certain other 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. Lease revenues from third-party tenants include $72 million, $43 million and $24 million recorded within food and beverage revenue for 2022, 2021 and 2020, respectively, and $118 million, $85 million and $60 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. Advertising. The Company expenses advertising costs as incurred. Advertising expense that primarily relates to media placement costs and which is generally included in general and administrative expenses, was $235 million, $121 million and $88 million for 2022, 2021 and 2020, respectively. Corporate expense. Corporate expense represents unallocated payroll, professional fees and various other expenses not directly related to the Company’s casino resort operations. In addition, corporate expense includes the costs associated with the Company’s evaluation and pursuit of new business opportunities, which are expensed as incurred. Preopening and start-up expenses. Preopening and start-up costs, including organizational costs, are expensed as incurred. Costs classified as preopening and start-up expenses include payroll, outside services, advertising, and other expenses related to new or start-up operations. Property transactions, net. The Company classifies transactions such as write-downs and impairments, demolition costs, and normal gains and losses on the sale of assets as “Property transactions, net.” See Note 16 for a detailed discussion of these amounts. Redeemable noncontrolling interest. Certain noncontrolling interest parties have non-voting economic interests in MGM National Harbor which provide for annual preferred distributions by MGM National Harbor to the noncontrolling interest parties based on a percentage of its annual net gaming revenue (as defined in the MGM National Harbor operating agreement). Such distributions are accrued each quarter and are paid 90 days after the end of each fiscal year. The noncontrolling interest parties each have the ability to require MGM National Harbor to purchase all or a portion of their interests for a purchase price based on a contractually agreed upon formula. The Company has recorded the interests as “Redeemable noncontrolling interests” in the mezzanine section of the accompanying consolidated balance sheets and not stockholders’ equity because their redemption is not exclusively in the Company’s control. The interests were initially accounted for at fair value. Subsequently, the Company recognizes changes in the redemption value as they occur and adjusts the carrying amount of the redeemable noncontrolling interests to equal the maximum redemption value, provided such amount does not fall below the initial carrying value, at the end of each reporting period. The Company records any changes caused by such an adjustment in capital in excess of par value. Additionally, the carrying amount of the redeemable noncontrolling interests is adjusted for accrued annual preferred distributions, with changes caused by such adjustments recorded within net income (loss) attributable to noncontrolling interests. Income per share of common stock. The table below reconciles basic and diluted income per share of common stock. Diluted net income attributable to common stockholders includes adjustments for redeemable noncontrolling interests. Diluted weighted average common and common equivalent shares include adjustments for potential dilution of stock-based awards outstanding under the Company’s stock compensation plan.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS AND DIVESTITURES	ACQUISITIONS AND DIVESTITURES LeoVegas acquisition. On May 2, 2022, the Company commenced a public offer to the shareholders of LeoVegas to tender 100% of the shares at a price of SEK 61 in cash per share. On September 7, 2022, the Company completed its tender offer and acquired 65% of the outstanding shares of LeoVegas and, at the completion of an extended acceptance period on September 22, 2022, acquired an additional 2% of outstanding shares, for an aggregate cash tender price of $370 million. During the tender offer period, the Company had acquired 31% of outstanding shares in open market purchases that had an acquisition-date fair value of approximately $172 million. As the Company’s previous 31% ownership interest was accounted for at fair value, no gain or loss was recorded upon consolidation. The remaining outstanding shares, with a fair value of approximately $11 million based upon the tender price, will be settled by the Company in cash in connection with squeeze-out proceedings. The acquisition provides the Company an opportunity to create a scaled global online gaming business. The Company recognized 100% of the assets, liabilities, and noncontrolling interests of LeoVegas at fair value at the date of the acquisition. The fair value of the acquired equity interests of LeoVegas was determined by the tender price and equaled $556 million, inclusive of cash settlement of equity awards. Under the acquisition method, the fair value was allocated to the assets acquired, liabilities assumed, and noncontrolling interests. T he Company estimated fair value using level 1 inputs, level 2 inputs, and level 3 inputs. The estimated fair values of the identified intangible assets were determined using methodologies under the income approach based on significant inputs that were not observable. The intangible assets include trademarks, which is an indefinite-lived intangible asset, and customer lists and technology, which are finite-lived intangibles that are amortized over each of their estimated useful lives of five years. Goodwill is primarily attributable to the profitability of LeoVegas in excess of identifiable assets and is not deductible for tax purposes. All of the goodwill was assigned to Corporate and other. The following table sets forth the purchase price allocation (in thousands): Cash and cash equivalents $ 93,407 Receivables and other current assets 36,872 Technology 109,027 Trademarks 144,374 Customer lists 126,526 Goodwill 288,367 Other long-term assets 19,181 Accounts payable, accrued liabilities, and other current liabilities (118,302) Debt (104,439) Other long-term liabilities (36,457) Noncontrolling interests (2,861) $ 555,695 The operating results for LeoVegas are included in the consolidated statements of operations from the date of acquisition. LeoVegas’ net revenue for the period from September 7, 2022 through December 31, 2022 was $133 million and operating loss and net loss were $13 million and $15 million, respectively. The Cosmopolitan acquisition. On May 17, 2022, the Company acquired 100% of the equity interests in the entities that own the operations of The Cosmopolitan for cash consideration of $1.625 billion plus working capital adjustments for a total purchase price of approximately $1.7 billion. The acquisition expands the Company’s customer base and provides a greater depth of choices and experiences for guests in Las Vegas. The Company recognized 100% of the acquired assets and assumed liabilities at fair value at the date of the acquisition. Under the acquisition method, the fair value was allocated to the assets acquired and liabilities assumed in the transaction. The Company estimated fair value using level 1 inputs, level 2 inputs, and level 3 inputs. The estimated fair values of the identified intangible assets were determined using methodologies under the income approach based on significant inputs that were not observable. The intangible assets include trademarks, which is an indefinite-lived intangible asset, and customer lists, which is amortized over its estimated useful life of seven years. Goodwill, which is deductible for tax purposes, is primarily attributable to the profitability of The Cosmopolitan in excess of identifiable assets as well as expected synergies. All of the goodwill was assigned to the Las Vegas Strip Resorts segment. The following table sets forth the purchase price allocation (in thousands): Cash and cash equivalents $ 80,670 Receivables and other current assets 94,354 Property and equipment 120,912 Trademarks 130,000 Customer lists 95,000 Goodwill 1,289,468 Operating lease right-of-use-assets, net 3,404,894 Other long- term assets 23,709 Accounts payable, accrued liabilities, and other current liabilities (145,136) Operating lease liabilities (3,401,815) Other long-term liabilities (1,570) $ 1,690,486 The operating results for The Cosmopolitan are included in the consolidated statements of operations from the date of acquisition. The Cosmopolitan’s net revenue for the period from May 17, 2022 through December 31, 2022 was $783 million and operating income and net income were $117 million and $117 million, respectively. CityCenter acquisition. On September 27, 2021, the Company acquired Infinity World’s 50% ownership interest in CityCenter for cash consideration of $2.125 billion. Prior to the acquisition, the Company held a 50% ownership interest, which was accounted for under the equity method. Through the acquisition, the Company obtained 100% of the equity interests and therefore consolidated CityCenter as of September 27, 2021. The fair value of the equity interests was determined by the transaction price and equaled $4.25 billion. The carrying value of the Company’s equity method investment was less than its share of the fair value of CityCenter at the acquisition date, resulting in a net gain of $1.6 billion upon consolidation, which was recognized as “Gain on consolidation of CityCenter, net” on the consolidated statements of operations. On September 28, 2021, the Company sold the real estate assets of Aria and Vdara for cash consideration of $3.89 billion and entered into a lease agreement pursuant to which the Company leases back the real property. The Company classified the real estate assets as held for sale as of the acquisition date and accordingly measured the real estate assets at fair value less costs to sell, as reflected in the table below. See Note 11 for discussion of the lease. The Company recognized 100% of the assets and liabilities of CityCenter at fair value at the date of the acquisition. Under the acquisition method, the fair value was allocated to the assets acquired and liabilities assumed in the transaction. The Company estimated fair value using level 1 inputs, level 2 inputs, and level 3 inputs. The fair value of the acquired indefinite-lived trademarks was determined using methodologies under the relief from royalty method based on significant inputs that were not observable. The goodwill is primarily attributable to the profitability of CityCenter in excess of identifiable assets, of which approximately 50% of the goodwill is deductible for income tax purposes. All of the goodwill was assigned to the Las Vegas Strip Resorts segment. The following table sets forth the purchase price allocation (in thousands): Cash and cash equivalents $ 335,396 Receivables and other current assets 106,417 Property and equipment - real estate assets held for sale 3,888,431 Property and equipment 323,093 Trademarks 180,000 Goodwill 1,397,338 Other long-term assets 13,923 Accounts payable, accrued liabilities, and other current liabilities (201,093) Debt (1,729,451) Other long-term liabilities (64,054) $ 4,250,000 CityCenter’s net revenue for the period from September 27, 2021 through December 31, 2021 was $367 million and operating income and net income were $69 million and $68 million, respectively. Unaudited pro forma information - CityCenter and The Cosmopolitan acquisitions. The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the Company’s acquisition of its controlling interest of CityCenter had occurred as of January 1, 2020 and the acquisition of The Cosmopolitan had occurred as of January 1, 2021. The pro forma information excludes the gain on consolidation of CityCenter and does not reflect transactions that occurred subsequent to acquisition, such as the Aria and Vdara real estate sale-leaseback transaction or the repayment of CityCenter’s assumed debt. The unaudited pro forma financial information below is not necessarily indicative of either future results of operations or results that might have been achieved had the acquisition been consummated as of the indicated date. Pro forma results of operations for the LeoVegas acquisition have not been included because it is not material to the consolidated results of operations. Year Ended December 31, 2022 2021 (In thousands) Net Revenues $ 13,550,304 $ 11,114,592 Net income attributable to MGM Resorts International 1,487,247 185,703 The Mirage transaction. On December 19, 2022, the Company completed the sale of the operations of The Mirage to an affiliate of Hard Rock for cash consideration of $1.075 billion subject to certain purchase price adjustments. At closing, the master lease between the Company and VICI was amended to remove The Mirage and to reflect a $90 million reduction in annual cash rent. The Company recognized a $1.1 billion gain recorded within “Property transactions, net.” The gain reflects the fair value of consideration received of $1.1 billion less the net carrying value of the assets and liabilities derecognized of $28 million. The operations of The Mirage are not classified as discontinued operations because the Company concluded that the sale is not a strategic shift that has a major effect on the Company’s operations or its financial results and it does not represent a major geographic segment or product line. VICI Transaction. On April 29, 2022, VICI acquired MGP in a stock-for-stock transaction. MGP Class A shareholders received 1.366 shares of newly issued VICI stock in exchange for each MGP Class A share outstanding and the Company received 1.366 units of VICI OP in exchange for each MGP OP unit held by the Company. The fixed exchange ratio represents an agreed upon price of $43 per share of MGP Class A share to the five-day volume weighted average price of VICI stock as of the close of business on July 30, 2021. In connection with the exchange, VICI OP redeemed the majority of the Company’s VICI OP units for cash consideration of $4.4 billion, with the Company retaining an approximate 1% ownership interest in VICI OP that had a fair value of approximately $375 million. MGP’s Class B share that was held by the Company was cancelled. Accordingly, the Company no longer holds a controlling interest in MGP and deconsolidated MGP upon the closing of the transactions. Further, the Company entered into an amended and restated master lease with VICI as discussed in Note 11. The lease between the Company and VICI BREIT Venture for the real estate assets of Mandalay Bay and MGM Grand Las Vegas remained unchanged. In connection with the transactions, the Company recognized a $2.3 billion gain recorded within “Gain on REIT transactions, net.” The gain reflects the fair value of consideration received of $4.8 billion plus the carrying amount of noncontrolling interest immediately prior to the transactions of $3.2 billion less the net carrying value of the assets and liabilities and accumulated comprehensive income derecognized of $5.7 billion. The major classes of assets and liabilities derecognized in connection with The Mirage and VICI transactions are as follows: VICI Transaction The Mirage (In thousands) Cash and cash equivalents $ 25,387 $ 26,230 Accounts receivable, net — 22,062 Inventories — 6,783 Income tax receivable 5,486 — Prepaid expenses and other 128 5,520 Property and equipment, net 9,250,519 26,724 Investments in and advances to unconsolidated affiliates 817,901 — Goodwill — 10,249 Other intangible assets, net — 3,095 Operating lease right-of-use assets, net 236,255 1,316,086 Other long-term assets, net 3,991 5,377 Total assets $ 10,339,667 $ 1,422,126 Accounts payable $ 1,136 $ 4,740 Accrued interest on long-term debt 68,150 — Other accrued liabilities 4,057 56,256 Deferred income taxes, net 1,284 — Long-term debt, net 4,259,473 — Operating lease liabilities 336,689 1,327,571 Other long-term obligations — 5,554 Total liabilities $ 4,670,789 $ 1,394,121 Gold Strike Tunica. On February 15, 2023, the Company completed the sale of the operations of Gold Strike Tunica to CNE for cash consideration of $450 million, subject to certain purchase price adjustments. At closing, the master lease between the Company and VICI was amended to remove Gold Strike Tunica and to reflect a $40 million reduction in annual cash rent. The operations of Gold Strike Tunica is not classified as discontinued operations because the Company concluded that the sale is not a strategic shift that has a major effect on the Company’s operations or its financial results and it does not represent a major geographic segment or product line. As the sale was completed subsequent to December 31, 2022, the asset group is classified as held for sale as of December 31, 2022. The major classes of assets and liabilities classified as held for sale as of December 31, 2022 are as follows (in thousands): Cash and cash equivalents $ 25,938 Accounts receivable, net 3,394 Inventories 1,186 Prepaid expenses and other 1,055 Property and equipment, net 20,871 Goodwill 40,523 Other intangible assets, net 5,700 Operating lease right-of-use assets, net 508,516 Other long-term assets, net 1,254 Assets held for sale $ 608,437 Accounts payable $ 3,719 Other accrued liabilities 18,385 Other long-term obligations 1,709 Operating lease liabilities 516,015 Liabilities related to assets held for sale $ 539,828

MGM Grand Paradise gaming subconcession. As described in Note 1, the enactment of the new Macau gaming law in June 2022 provided for material changes to the legal form of gaming concessions in Macau, including discontinuing and prohibiting gaming subconcessions subsequent to their expiration, and also included material changes to the rights and obligations provided for under the new gaming concessions. As a result, the Company determined that the MGM Grand Paradise gaming subconcession and new gaming concession are two separate units of account. Further, as the material changes in the legal and regulatory environment could have an adverse effect on the value of MGM Grand Paradise’s gaming subconcession, the Company concluded that a triggering event had occurred under ASC 360 in June 2022 for the MGM China asset group. The Company compared the estimated undiscounted cash flows of the asset group to its carrying value and determined that the undiscounted cash flows significantly exceeded the carrying value and, therefore, no impairment was indicated. Additionally, in June 2022, the Company reassessed the useful life of the gaming subconcession intangible asset and determined that, given the new gaming law and the resulting changes described above, the useful life would no longer be based on the initial term of the MGM Cotai land concession, which ends in January 2038, and that the useful life should be revised to align with the cessation of the subconcession rights that occurred at the end of the contractual term of the gaming subconcession, which ended on December 31, 2022. Accordingly, amortization of the MGM Grand Paradise gaming subconcession was recognized on a straight-line basis over its reduced useful life. The gaming subconcession was fully amortized as of December 31, 2022. Amortization expense related to intangible assets was $2.7 billion, $197 million and $194 million for 2022, 2021, and 2020, respectively. As of December 31, 2022, estimated future amortization is as follows: Years ending December 31, (In thousands) 2023 $ 77,200 2024 75,214 2025 73,428 2026 71,643 2027 54,602 Thereafter 59,674 $ 411,761

In November 2021, the Company terminated its previous revolving facility and entered into a new $1.675 billion revolving credit facility maturing in November 2026. The revolving credit facility bears interest of SOFR plus 1.50% to 2.25% determined by reference to a rent adjusted total net leverage ratio pricing grid. At December 31, 2022, no amounts were drawn. On February 14, 2020, in connection with the MGM Grand Las Vegas and Mandalay Bay transaction, the Company used proceeds from the transaction to repay and terminate the $1.5 billion outstanding on its then existing revolving facility in full and entered into an unsecured credit agreement, comprised of a $1.5 billion unsecured revolving facility that would mature in February 2025. As a result, 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 secured credit facility is guaranteed by each of the Company’s existing direct and indirect wholly-owned material domestic restricted subsidiaries, subject to certain exclusions. The senior secured credit facility is secured by a pledge of the equity in certain of the Company's domestic operating properties. Mandatory prepayments will be required upon the occurrence of certain events, including sales of certain assets, subject to certain exceptions. The Company’s senior secured credit facility also contains customary representations and warranties, events of default and positive and negative covenants. The Company was in compliance with its credit facility covenants at December 31, 2022. MGP OP senior secured credit facility and bridge facility. In April 2022, MGP OP senior secured credit facility was derecognized in connection with the deconsolidation of MGP as a result of the VICI Transaction. In February 2020, in connection with the MGM Grand Las Vegas and Mandalay Bay transaction, MGP OP amended its senior secured credit facility to, among other things, allow for the transaction to occur, permit the incurrence by MGP OP of a nonrecourse guarantee relating to the debt of VICI BREIT Venture (refer to Note 12 for description of such guarantee), and permit the incurrence of the bridge loan facility. As a result of the transaction and the amendment, MGP OP repaid its $1.3 billion outstanding term loan B facility in full with the proceeds of a bridge facility, which was then assumed by VICI BREIT Venture as partial consideration for MGP OP’s contribution. Additionally, MGP OP used the proceeds from the settlement of the forward equity issuances to pay off the outstanding balance of $399 million on its term loan A facility in full. As a result, MGP OP incurred an $18 million loss on early retirement of debt recorded in “Other, net” in the consolidated statements of operations. MGP OP was party to interest rate swaps to mitigate the effects of interest rate volatility inherent in its variable rate debt as well as forecasted debt issuances. In March 2022, MGP OP terminated its interest rate swap agreements. MGM China first revolving credit facility. At December 31, 2022, the MGM China first revolving credit facility consisted of a HK$9.75 billion unsecured revolving credit facility, which was fully drawn.

The MGM China first revolving credit facility contains customary representations and warranties, events of default, and positive, negative and financial covenants, including that MGM China maintains compliance with a maximum leverage ratio and a minimum interest coverage ratio. Due to the impact of COVID-19, in February 2021, MGM China amended its first revolving credit agreement to provide for a waiver of its maximum leverage ratio and its minimum interest coverage ratio through the fourth quarter of 2022. In February 2022, MGM China further amended its first revolving credit facility to extend the financial covenant waivers through maturity in May 2024. MGM China was in compliance with its applicable MGM China first revolving credit facility covenants at December 31, 2022. MGM China second revolving credit facility.

Draws will be subject to satisfaction of certain conditions precedent, including evidence that the MGM China first revolving credit facility has been fully drawn. At December 31, 2022, $224 million was drawn on the MGM China second revolving credit facility and the weighted average interest rate was 7.72%.

In February 2022, MGM China further amended its second revolving credit facility to extend the financial covenant waivers through maturity in May 2024. MGM China was in compliance with its applicable MGM China second revolving credit facility covenants at December 31, 2022. LeoVegas revolving credit facility. Upon the Company’s acquisition of LeoVegas, the LeoVegas revolving credit facility consisted of a €40 million revolving facility, which was fully drawn. The LeoVegas revolving credit facility contained a change-of-control provision which required repayment of the facility within 60 days following a change-of- control event. As the Company’s acquisition of LeoVegas triggered the change-of-control provision, the revolving credit facility was repaid in November 2022. CityCenter senior credit facility.

The FTCs are attributable to the Macau Special Gaming Tax, which is 35% of gross gaming revenue in Macau. Because MGM Grand Paradise is presently exempt from the Macau 12% complementary tax on gaming profits, the Company believes payment of the Macau Special Gaming Tax qualifies as a tax paid in lieu of an income tax that is creditable against U.S. taxes. While the Company generally does not expect to generate new FTC carryovers after the year ended December 31, 2017, it will be able to utilize its existing FTC carryovers to the extent it has active foreign source income during the 10-year FTC carryforward period. Such foreign source income includes the recapture, to the extent of a portion of U.S. taxable income each year, of overall domestic losses that totaled approximately $356 million at December 31, 2022. The Company relies on future U.S. source operating income in assessing utilization of the overall domestic losses and, by extension, future FTC realization during the 10-year FTC carryover period. The FTC carryovers will expire if not utilized as follows: $976 million in 2023; $780 million in 2024; $674 million in 2025; $134 million in 2026; and $200 million in 2027. The Company’s assessment of the realization of its FTC deferred tax asset is based on available evidence, including assumptions concerning future U.S. operating profits and foreign source income. As a result, significant judgment is required in assessing the possible need for a valuation allowance and changes to such assumptions could result in a material change in the valuation allowance with a corresponding impact on the provision for income taxes in the period including such change. On September 5, 2022, MGM Grand Paradise was granted an extension of its exemption from the Macau 12% complementary tax on gaming profits through December 31, 2022, concurrent with the end of the term of its gaming subconcession. Absent the exemption from complementary tax on gaming profits, “Net income attributable to MGM Resorts International” would have increased by $3 million in 2022 and decreased by $10 million in 2021 and diluted earnings per share would have increased by $0.01 in 2022 and decreased by $0.02 in 2021. The Company continues to assume that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond December 31, 2022 and has factored that assumption into the measurement of Macau deferred tax assets and liabilities. Non-gaming operations remain subject to the Macau complementary tax. At December 31, 2022, foreign net operating loss carryforwards primarily consisted of a complementary tax NOL carryforward of $1.6 billion at MGM Grand Paradise resulting from non-gaming operations that will expire if not utilized in years 2023 through 2025. MGM Grand Paradise’s exemption from the 12% complementary tax on gaming profits does not apply to dividend distributions of such profits to MGM China. Through the year ended December 31, 2022, in lieu of the 12% complementary tax that would otherwise be due by its shareholder, MGM China, on distributions of its gaming profits, MGM Grand Paradise agreed to pay a flat annual payment of approximately $2 million regardless of the amount of distributable dividends. There is a $245 million valuation allowance on certain foreign deferred tax assets, which primarily relates to Macau deferred tax assets at MGM Grand Paradise. The valuation allowance on Macau deferred tax assets increased by $89 million during 2022 as a result of accelerating amortization for the remaining useful life of the MGM Grand Paradise gaming subconcession. The Company has NOLs in some of the states in which it operates that total $373 million as of December 31, 2022, which equates to deferred tax assets of $23 million after federal tax effect and before valuation allowance. The NOL carryforwards in most of the states will expire, if not utilized, between 2025 through 2041. Otherwise, the NOL carryforward can be carried forward indefinitely. The Company has provided a valuation allowance of $8 million on some of its state deferred tax assets for the NOLs described above. A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits is as follows: Year Ended December 31, 2022 2021 2020 (In thousands) Gross unrecognized tax benefits at January 1 $ 19,568 $ 35,617 $ 33,298 Gross increases - prior period tax positions — 12,949 3,717 Gross decreases - prior period tax positions (12,968) (13,388) (1,398) Gross increases - current period tax positions 285 654 — Settlements with Taxing Authorities — (16,264) — Gross unrecognized tax benefits at December 31 $ 6,885 $ 19,568 $ 35,617 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $7 million and $11 million at December 31, 2022 and 2021, respectively. The Company recognizes interest and penalties related to unrecognized tax benefits in income tax expense, which were not material for each of the periods presented. The Company files income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and foreign jurisdictions, although the income taxes paid in foreign jurisdictions are not material. As of December 31, 2022, other than adjustments resulting from the federal and state income tax audits discussed herein, the federal, state, and local tax jurisdictions in which the Company files tax returns generally cannot assess tax with respect to years ended prior to 2016.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES 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. Commitments. MGM Grand Paradise concession contract. Pursuant to the concession contract, MGM Grand Paradise is required to pay (i) a special gaming tax of 35% of gross gaming revenue, which is subject to a minimum annual payment that would be levied in the form of a special premium in the event the minimum amount is not achieved, (ii) a fixed annual premium, (iii) a variable premium based on the number of gaming tables and machines, and (iv) special levies of up to 5% of gross gaming revenue. In addition, MGM Grand Paradise is required to make annual payments in connection with the temporary use of the reverted gaming assets based upon square meters of the reverted casino areas. Based upon the approved number of gaming tables and slot machines, estimates of the Macau average price index, and square meters of the reverted casino areas, each as of January 1, 2023, the minimum future payments for the above obligations are approximately MOP 22.8 billion ($2.8 billion as of December 31, 2022). The gaming concession also obligates MGM Grand Paradise to invest in various gaming and non-gaming projects and the development of international tourist markets over the ten-year term of the concession in an amount of approximately MOP 16.7 billion ($2.1 billion as of December 31, 2022) of which MOP 15 billion ($1.9 billion as of December 31, 2022) is designated for non-gaming projects, for which the non-gaming commitment is subject to increases of up to 20% in the following years if the market-wide Macau annual gross gaming revenue achieves or exceeds MOP 180 billion ($22.4 billion as of December 31, 2022). The increased commitment is subject to a 4% reduction per year if the triggering event occurs on or after the sixth year of the term of the concession contract. The projects related to the investment are subject to annual review and Macau government approval and, therefore, the timing and magnitude of the projects comprising the investment are subject to change. The gaming law also requires concessionaires to maintain share capital of at least MOP 5 billion (approximately $622 million as of December 31, 2022), which further required a cash deposit of such amount until commencement of activity under the concession on January 1, 2023 at which point the deposit was available for use in operations, provided that the net asset value of the concessionaire is not at any time less than such amount. 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 $1.35 billion . At December 31, 2022, $31 million in letters of credit were outstanding under the Company’s senior credit facility. The amount of available borrowings under the credit facility is reduced by any outstanding letters of credit. MGM China bank guarantees.

In connection with the expiration of the gaming subconcession and issuance of the gaming concession in January 2023, the bank guarantees were cancelled and bank guarantees, secured by pledged cash, were provided to the government of Macau in the amount of MOP 1 billion (approximately $124 million as of December 31, 2022) to warrant the fulfillment of labor liabilities and of damages or losses that may result if there is noncompliance with the concession. The guarantees expire 180 days after the end of the concession term. Bellagio BREIT Venture shortfall 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. VICI BREIT Venture shortfall guarantee. The Company provides a shortfall guarantee of the $3.0 billion principal amount of indebtedness (and any interest accrued and unpaid thereon) of VICI BREIT Venture, which has an initial term of 12 years, maturing in 2032, with an anticipated repayment date of March 2030.

In addition, Ms. Ho indirectly holds a 50% interest in an entity th at provides, along with its subsidiary, marketing and public relations consulting services, including for the tendering of MGM China's gaming concession, to MGM China, which totaled $5 million , $4 million, and $1 million for the years ended December 31, 2022, 2021, and 2020, respectively. On September 1, 2016, the Company purchased 188.1 million common shares of its MGM China subsidiary from Grand Paradise Macau (“GPM”), an entity controlled by Ms. Ho. As part of the consideration for the purchase, the Company agreed to pay GPM or its nominee a deferred cash payment of $50 million. The payments included amounts equal to the ordinary dividends received on such shares, with a final lump sum payment due on the fifth anniversary of the closing date of the transaction, which was made in September 2021. Such amounts were paid to Expert Angels Limited, an entity controlled by an immediate family member of Ms. Ho. MGM Branding and Development Holdings, Ltd. (together with its subsidiary MGM Development Services, Ltd., “MGM Branding and Development”), an entity included in the Company’s consolidated financial statements in which Ms. Ho indirectly holds a noncontrolling interest, is party to a brand license agreement and a development services agreement with MGM China, for which the related amounts are eliminated in consolidation. An entity owned by Ms. Ho received distributions of $5 million, $8 million and $5 million for the years ended December 31, 2022, 2021 and 2020, respectively, in connection with the ownership of a noncontrolling interest in MGM Branding and Development Holdings, Ltd. On August 21, 2022, Ms. Ho and MGM Grand Paradise entered into an agreement for her services as Managing Director of MGM Grand Paradise during the term of the new concession (the “Services Agreement”). The Services Agreement became effective on January 1, 2023 after satisfying certain conditions precedent as defined in the agreement. Pursuant to the Services Agreement, Ms. Ho will receive compensation of $8 million annually during the term of the concession and will be entitled to incentive payments up to an aggregate total amount of $95 million. The amount of the incentive payments earned are subject to the achievement of certain EBITDA targets, as defined in the agreement. MGP Prior to the closing of the VICI Transaction, the Company leased 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, MGM Northfield Park, and MGM Springfield pursuant to a master lease with MGP. In February 2020, Mandalay Bay was removed from the master lease with MGP in connection with the MGM Grand Las Vegas and Mandalay Bay transaction and the annual cash rent under the master lease with MGP was reduced by $133 million to a total of $813 million. The annual cash rent payments under the master lease with MGP for the fifth lease year, which commenced on April 1, 2020, increased to $828 million from $813 million, as a result of a 2% fixed annual rent escalator that went into effect on April 1, 2020. The annual cash rent payments under the master lease with MGP for the sixth lease year, which commenced on April 1, 2021, increased to $843 million from $828 million, as a result of a 2% fixed annual rent escalator that went into effect on April 1, 2021. On October 29, 2021, MGP acquired the real estate assets of MGM Springfield from the Company for $400 million of cash consideration, which was accounted for as a transaction between entities under common control. The Company adjusted the carrying value of noncontrolling interests to adjust for its share of the difference between the carrying value of the net assets transferred and the consideration received, with offsetting adjustments to capital in excess of par value. The master lease with MGP was amended to add MGM Springfield and reflect a $30 million increase in annual cash rent to a total of $873 million. Until final regulatory approvals are obtained, which were not necessary for the transaction to close, the Company and VICI (as the landlord of the property following the VICI Transaction) are subject to a trust agreement, which provides for the property to go into a trust (or, at the Company’s option, be returned to the Company) during the interim period in the event that the regulator finds reasonable cause to believe that VICI may not be found suitable. The property would then remain in trust until a final determination regarding VICI’s suitability is made. The annual cash rent payments under the master lease with MGP for the seventh lease year, which commenced on April 1, 2022, increased to $877 million from $873 million, due to the sixth 2% annual base rent escalator that went into effect on April 1, 2022, as the adjusted net revenue to rent ratio on which such escalator was contingent was met, which increased annual cash rent by $16 million, partially offset by the percentage rent reset that went into effect on April 1, 2022, calculated based on the percentage of average actual annual net revenue of the leased properties during the preceding five year period, which decreased annual cash rent by $12 million. In April 2022, the Company completed the VICI Transaction, which resulted in the deconsolidation of MGP, including its investment in the VICI BREIT Venture. Refer to Note 4 for additional information on the VICI Transaction. As part of the transaction, the Company entered into an amended and restated master lease with VICI. Refer to Note 11 for further discussion on the master lease with VICI. All intercompany transactions, including transactions under the master lease with MGP, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares was recognized as noncontrolling interests in the Company’s consolidated financial statements. Bellagio BREIT Venture The Company has a 5% ownership interest in Bellagio BREIT Venture, which owns the real estate assets of Bellagio and leases such assets to a subsidiary of the Company pursuant to a lease agreement. Refer to Note 11 for further information related to the Bellagio lease.

Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation. 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 variable interest entity (“VIE”). The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. 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 . The venture (the “Bellagio BREIT Venture”) that is 5% owned by a subsidiary of the Company and 95% owned by a subsidiary of BREIT 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 is not the primary beneficiary of Bellagio BREIT Venture because the Company does not have power to direct the activities that could potentially be significant to the venture as BREIT, as the managing member, has such power; accordingly, the Company does not consolidate the venture. The Company’s maximum exposure to loss in Bellagio BREIT Venture is equal to the carrying value of its investment of $56 million as of December 31, 2022, assuming no future capital funding requirements, plus the exposure to loss resulting from the Company’s guarantee of the debt of Bellagio BREIT Venture, which guarantee is immaterial as of December 31, 2022, as further discussed in Note 12. For entities determined not to be a 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 under the voting interest model if it has a controlling financial interest 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 and all intercompany balances and transactions are eliminated in consolidation. If the entity does not qualify for consolidation under the voting interest model and the Company has significant influence over the operating and financial decisions of the entity, the Company generally accounts for the entity under the equity method, such as BetMGM, which does not qualify for consolidation as the Company has joint control, given the entity is structured with substantive participating rights whereby both owners participate in the decision making process, which prevents the Company from exerting a controlling financial interest in such entity, as defined in ASC 810. For entities over which the Company does not have significant influence, such as VICI OP, the Company accounts for its equity investment under ASC 321.
Reclassifications	Reclassifications . Certain reclassifications have been made to conform the prior period presentation.
Management's use of estimates	Management’s use of estimates. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. These principles require the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair value measurements	Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates or equity interests, assets acquired, and liabilities assumed in an acquisition, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are quoted prices for identical or comparable instruments or pricing using observable market data; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 inputs when measuring its equity investments recorded at fair value; • Level 2 inputs for its long-term debt fair value disclosures. See Note 9; • Level 1 and Level 2 inputs for its debt investments; and • Level 1, Level 2, and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed in acquisitions. See Note 4. Equity investments. Fair value is measured based upon trading prices on the applicable securities exchange for equity investments for which the Company has elected the fair value option of Accounting Standards Codification (“ASC”) 825, such as LeoVegas (prior to consolidation), and equity investments accounted for under ASC 321 that have a readily determinable fair value, such as VICI OP. The fair value of these investments was $461 million and $66 million as of December 31, 2022 and 2021, respectively, and is reflected within “Other long-term assets, net” on the consolidated balance sheets. Gains and losses are recorded in “Other, net” in the statements of operations. For the years ended December 31, 2022, and 2021 the Company recorded a net gain on its equity investments of $10 million and $28 million, respectively. Debt investments. The Company’s investments in debt securities are classified as trading securities and recorded at fair value. Gains and losses are recorded in “Other, net” in the statement of operations. Debt securities are considered cash equivalents if the criteria for such classification is met or otherwise classified as short-term investments within “Prepaid expenses and other” since the investment of cash is available for current operations. The following tables present information regarding the Company’s debt investments: Fair value level December 31, 2022 (In thousands) Cash and cash equivalents: Money market funds Level 1 $ 12,009 Commercial paper and certificates of deposit Level 2 5,992 Cash and cash equivalents 18,001 Short-term investments: U.S. government securities Level 1 56,835 U.S. agency securities Level 2 9,530 Commercial paper and certificates of deposit Level 2 4,466 Corporate bonds Level 2 213,875 Short-term investments 284,706 Total debt investments $ 302,707
Cash and cash equivalents and Restricted cash	Cash and cash equivalents. Cash and cash equivalents include cash on hand, investments and interest-bearing instruments that are highly liquid with maturities of 90 days or less at the date of acquisition. Book overdraft balances resulting from the Company’s cash management program are recorded within “Accounts and construction payable.” Restricted cash. Cash held in an escrow account related to the reverse termination fee that was contractually required to be prefunded for The Cosmopolitan acquisition was reflected as “Restricted Cash” on the consolidated balance sheets as of December 31, 2021. “Restricted Cash” and “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of December 31, 2021. MGM China’s pledged cash of $124 million securing the bank guarantees discussed in Note 12 is restricted in use and classified within “Other long-term assets, net.” Such amount plus “Cash and cash equivalents” on the consolidated balance sheets equal “Cash, cash equivalents, and restricted cash” on the consolidated statements of cash flows as of December 31, 2022.
Accounts receivable and credit risk	Accounts receivable and credit risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of casino receivables. The Company issues credit following background checks and investigations of creditworthiness. At December 31, 2022 and 2021, approximately 52% and 53%, respectively, of the Company’s gross accounts receivable related to casino receivables.
Inventories	Inventories. Inventories consist primarily of food and beverage, retail merchandise and operating supplies, and are stated at the lower of cost or net realizable value. Cost is determined primarily using the average cost method for food and beverage and operating supplies. Cost for retail merchandise is determined using the cost method.
Property and equipment	Property and equipment. Property and equipment are stated at cost. A significant amount of the Company’s property and equipment was acquired through business combinations and therefore recognized at fair value at the acquisition date. Gains or losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. Property and equipment are generally depreciated over the following estimated useful lives on a straight-line basis: Buildings and improvements 15 to 40 years Land improvements 10 to 20 years Furniture and fixtures 3 to 20 years Equipment 3 to 15 years The Company evaluates its property and equipment and other long-lived assets for impairment based on its classification as held for sale or to be held and used. Several criteria must be met before an asset is classified as held for sale, including that management with the appropriate authority commits to a plan to sell the asset at a reasonable price in relation to its fair value and is actively seeking a buyer. For assets held for sale, the Company recognizes the asset at the lower of carrying value or fair market value less costs to sell, as estimated based on comparable asset sales, offers received, or a discounted cash flow model. For assets to be held and used, the Company reviews for impairment whenever indicators of impairment exist. The Company then compares the estimated future cash flows of the asset group, on an undiscounted basis, to the carrying value of the asset group. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset, typically measured using a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs. All recognized impairment losses, whether for assets held for sale or assets to be held and used, are recorded as operating expenses.
Capitalized interest	Capitalized interest. The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. When no debt is incurred specifically for a project, interest is capitalized on amounts expended on the project using the weighted average cost of the Company’s outstanding borrowings. Capitalization of interest ceases when the project is substantially complete, or development activity is suspended for more than a brief period.
Investments in and advances to unconsolidated affiliates	Investments in and advances to unconsolidated affiliates. The Company has investments in unconsolidated affiliates accounted for under the equity method. Under the equity method, carrying value is adjusted for the Company’s share of the investees’ earnings and losses, amortization of certain basis differences, as well as capital contributions to and distributions from these companies. Distributions in excess of equity method earnings are recognized as a return of investment and recorded as investing cash inflows in the accompanying consolidated statements of cash flows. The Company classifies operating income and losses as well as gains and impairments related to its investments in unconsolidated affiliates as a component of operating income or loss and classifies non-operating income or losses related to its investments in unconsolidated affiliates as a component of non-operating income or loss, as the Company’s investments in such unconsolidated affiliates are an extension of the Company’s core business operations.
Goodwill and other intangible assets	Goodwill and other intangible assets. Goodwill represents the excess of purchase price over fair market value of net assets acquired in business combinations. Indefinite-lived intangibles consist of trademarks and certain of our gaming licenses. Goodwill and indefinite-lived intangible assets must be reviewed for impairment at least annually and between annual test dates in certain circumstances. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. No material impairments were indicated or recorded as a result of the annual impairment review for goodwill and indefinite-lived intangible assets in 2022, 2021, and 2020. Accounting guidance provides entities the option to perform a qualitative assessment of goodwill and indefinite-lived intangible assets (commonly referred to as “step zero”) in order to determine whether further impairment testing is necessary. In performing the step zero analysis the Company considers macroeconomic conditions, industry and market considerations, current and forecasted financial performance, entity-specific events, and changes in the composition or carrying amount of net assets of reporting units for goodwill. In addition, the Company takes into consideration the amount of excess of fair value over carrying value determined in the last quantitative analysis that was performed, as well as the period of time that has passed since the last quantitative analysis. If the step zero analysis indicates that it is more likely than not that the fair value is less than its carrying amount, the entity would proceed to a quantitative analysis. Under the quantitative analysis, goodwill for relevant reporting units is tested for impairment using a discounted cash flow analysis based on the estimated future results of the Company’s reporting units discounted using market discount rates and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. If the fair value of the reporting unit is less than its carrying value, an impairment charge is recognized equal to the difference. Under the quantitative analysis, license rights are tested for impairment using a discounted cash flow approach, and trademarks are tested for impairment using the relief-from-royalty method. If the fair value of an indefinite-lived intangible asset is less than its carrying amount, an impairment loss is recognized equal to the difference.
Note receivable	Note receivable. In connection with the sale of Circus Circus Las Vegas and the adjacent land in December 2019, the Company received a secured note due in 2024 with a face value of $163 million and fair value of $134 million. The note has a stated interest rate of 3% for the first two years, 4% for following two years, and 4.5% for the fifth year and is secured by the borrower with the land adjacent to Circus Circus Las Vegas as collateral with an effective interest rate of 7.31%. The interest on the note, which is comprised of the stated interest and the discount on the note, amortizes into interest income using the effective interest method over the length of the agreement. The carrying value of the note receivable was $167 million and $155 million as of December 31, 2022 and 2021, respectively, and was recorded within “Other long-term assets, net” in the consolidated balance sheets.
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. The transaction price for a casino wager is the difference between gaming wins and losses (“net win”). In certain circumstances, the Company offers discounts on markers, which is estimated based upon historical business practice, and recorded as a reduction of casino revenue. Commissions rebated to gaming promoters and VIP players at MGM China are also recorded as a reduction of casino revenue. The Company accounts for casino revenue on a portfolio basis given the similar characteristics of wagers by recognizing net win per gaming day versus on an individual wager basis. For casino wager transactions that include other goods and services provided by the Company to gaming patrons on a discretionary basis to incentivize gaming, the Company allocates revenue from the casino wager transaction to the good or service delivered based upon standalone selling price (“SSP”). Discretionary goods and services provided by the Company and supplied by third parties are recognized as an operating expense. 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 SSP 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. After allocating revenue to other goods and services provided as part of casino wager transactions, the Company records the residual amount to casino revenue . The transaction price of rooms, food and beverage, and retail contracts is the net amount collected from the customer for such goods and services. The transaction price for such contracts is recorded as revenue when the good or service is transferred to the customer over their stay at the hotel or when the delivery is made for the food & beverage and retail & other contracts. Sales and usage-based taxes are excluded from revenues. For some arrangements, the Company acts as an agent in that it arranges for another party to transfer goods and services and the Company is not the controlling entity, which primarily include certain of the Company’s entertainment shows and, in certain jurisdictions, the Company’s arrangement with BetMGM for online sports betting and iGaming. The Company also has other contracts that include multiple goods and services, such as packages that bundle food, beverage, or entertainment offerings with hotel stays and convention services. For such arrangements, the Company allocates revenue to each good or service based on its relative SSP. The Company primarily determines the SSP of rooms, food and beverage, entertainment, and retail goods and services based on the amount that the Company charges when sold separately in similar circumstances to similar customers. 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, 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 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 2022 2021 2022 2021 2022 2021 (In thousands) Balance at January 1 $ 176,219 $ 212,671 $ 144,465 $ 139,756 $ 640,001 $ 382,287 Balance at December 31 185,669 176,219 183,602 144,465 816,376 640,001 Increase / (decrease) $ 9,450 $ (36,452) $ 39,137 $ 4,709 $ 176,375 $ 257,714 The December 31, 2022 balances exclude liabilities related to assets held for sale. See Note 4. Reimbursed cost. Costs reimbursed pursuant to management services are recognized as revenue in the period it incurs the costs as this reflects when the Company performs its related performance obligation and is entitled to reimbursement. Reimbursed costs related primarily to the Company’s management of CityCenter (such management agreement was terminated upon the acquisition of CityCenter in September 2021). 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
Leases	Leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period of time in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. The Company classifies a lease with terms greater than twelve months as either operating or finance. At commencement, the right-of-use (“ROU”) assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term. The initial measurement of ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, such as for the Company’s triple-net operating leases for which the lessor has provided its implicit rate or provided the assumptions required for the Company to readily determine the rate implicit in the lease, the Company uses the rate implicit in the lease to discount lease payments to present value. However, for most of the Company’s leases, such as its ground subleases and equipment leases, the Company cannot readily determine the implicit rate. Accordingly, the Company uses its incremental borrowing rate to discount the lease payments for such leases based on the information available at the commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. The Company’s triple-net operating leases each contain renewal periods at the Company’s option, each of which are not considered to be reasonably certain of being exercised. Many of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. For operating leases, lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. For finance leases, the ROU asset depreciates on a straight-line basis over the shorter of the lease term or useful life of the ROU asset and the lease liability accretes interest based on the interest method using the discount rate determined at lease commencement. Refer to Note 11 for discussion of leases under which the Company is a lessee. Refer to Note 18 for discussion of the master lease with MGP. The Company is a lessor under certain other 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. Lease revenues from third-party tenants include $72 million, $43 million and $24 million recorded within food and beverage revenue for 2022, 2021 and 2020, respectively, and $118 million, $85 million and $60 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.

Lease revenues from third-party tenants include $72 million, $43 million and $24 million recorded within food and beverage revenue for 2022, 2021 and 2020, respectively, and $118 million, $85 million and $60 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.
Advertising	Advertising. The Company expenses advertising costs as incurred. Advertising expense that primarily relates to media placement costs and which is generally included in general and administrative expenses, was $235 million, $121 million and $88 million for 2022, 2021 and 2020, respectively.
Corporate expense	Corporate expense. Corporate expense represents unallocated payroll, professional fees and various other expenses not directly related to the Company’s casino resort operations. In addition, corporate expense includes the costs associated with the Company’s evaluation and pursuit of new business opportunities, which are expensed as incurred.
Preopening and start-up expenses	Preopening and start-up expenses. Preopening and start-up costs, including organizational costs, are expensed as incurred. Costs classified as preopening and start-up expenses include payroll, outside services, advertising, and other expenses related to new or start-up operations.
Property transactions, net	Property transactions, net. The Company classifies transactions such as write-downs and impairments, demolition costs, and normal gains and losses on the sale of assets as “Property transactions, net.” See Note 16 for a detailed discussion of these amounts.
Redeemable noncontrolling interest	Redeemable noncontrolling interest. Certain noncontrolling interest parties have non-voting economic interests in MGM National Harbor which provide for annual preferred distributions by MGM National Harbor to the noncontrolling interest parties based on a percentage of its annual net gaming revenue (as defined in the MGM National Harbor operating agreement). Such distributions are accrued each quarter and are paid 90 days after the end of each fiscal year. The noncontrolling interest parties each have the ability to require MGM National Harbor to purchase all or a portion of their interests for a purchase price based on a contractually agreed upon formula.
Income per share of common stock	Income per share of common stock. The table below reconciles basic and diluted income per share of common stock. Diluted net income attributable to common stockholders includes adjustments for redeemable noncontrolling interests. Diluted weighted average common and common equivalent shares include adjustments for potential dilution of stock-based awards outstanding under the Company’s stock compensation plan. Year Ended December 31, 2022 2021 2020 Numerator: (In thousands) Net income (loss) attributable to MGM Resorts International $ 1,473,093 $ 1,254,370 $ (1,032,724) Adjustment related to redeemable noncontrolling interests (31,888) (78,298) 35,520 Net income (loss) available to common stockholders - basic and diluted $ 1,441,205 $ 1,176,072 $ (997,204) Denominator: Weighted average common shares outstanding basic 409,201 481,930 494,152 Potential dilution from stock-based awards 3,792 5,426 — Weighted average common and common equivalent shares - diluted 412,993 487,356 494,152 Antidilutive stock-based awards excluded from the calculation of diluted earnings per share 603 198 9,493
