Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	NOTE 1 — ORGANIZATION Organization. MGM Resorts International (together with its consolidated subsidiaries, unless otherwise indicated or unless the context requires otherwise, the “Company”) is a Delaware corporation that acts largely as a holding company and, through subsidiaries, owns and operates casino resorts. As discussed further below, the Company leases certain of its real estate assets from MGM Growth Properties Operating Partnership LP (the “Operating Partnership”), which is a consolidated subsidiary. The Company owns and operates the following integrated casino, hotel and entertainment resorts in Las Vegas, Nevada: Bellagio, MGM Grand Las Vegas, The Mirage, Mandalay Bay, Luxor, New York-New York, Monte Carlo, Excalibur and Circus Circus Las Vegas. Operations at MGM Grand Las Vegas include management of The Signature at MGM Grand Las Vegas, a condominium-hotel consisting of three towers. The Company operates and, along with local investors, owns MGM Grand Detroit in Detroit, Michigan and MGM National Harbor in Prince George’s County, Maryland. The Company also owns and operates the Borgata Hotel Casino & Spa (“Borgata”), located on Renaissance Pointe in the Marina area of Atlantic City, New Jersey and the following resorts in Mississippi: Beau Rivage in Biloxi and Gold Strike in Tunica. Additionally, the Company owns and operates The Park, a dining and entertainment district located between New York-New York and Monte Carlo, Shadow Creek, an exclusive world-class golf course located approximately ten miles north of its Las Vegas Strip resorts, Primm Valley Golf Club at the California/Nevada state line and Fallen Oak golf course in Saucier, Mississippi. The Company indirectly owns 76.3% of the partnership units in the Operating Partnership, a subsidiary of MGM Growth Properties LLC (“MGP”). MGP owns the remaining 23.7% ownership interest in the Operating Partnership units and also owns 100% of the general partner. MGP is organized as an umbrella partnership REIT (commonly referred to as an “UPREIT”) structure in which substantially all of its assets are owned by and substantially all of its businesses are conducted through the Operating Partnership. MGP has two classes of authorized and outstanding voting common shares (collectively, the “shares”): Class A shares and a single Class B share. The Company owns MGP’s Class B share, which does not provide its holder any rights to profits or losses or any rights to receive distributions from operations of MGP or upon liquidation or winding up of MGP. MGP’s Class A shareholders are entitled to one vote per share, while the Company, as the owner of the Class B share, is entitled to an amount of votes representing a majority of the total voting power of MGP’s shares so long as the Company and its controlled affiliates’ (excluding MGP) aggregate beneficial ownership of the combined economic interests in MGP and the Operating Partnership does not fall below 30%. The Operating Partnership units held by the Company are exchangeable into Class A shares of MGP on a one-to-one basis, or cash at the fair value of a Class A share. The determination of settlement method is at the option of MGP’s independent conflicts committee. Pursuant to a master lease agreement between a subsidiary of the Company (the “Tenant”) and a subsidiary of the Operating Partnership (the “Landlord”), the Company leases the real estate assets of The Mirage, Mandalay Bay, Luxor, New York-New York, Monte Carlo, Excalibur, The Park, Borgata, Gold Strike Tunica, MGM Grand Detroit and Beau Rivage from subsidiaries of the Operating Partnership. See Note 11 for additional information related to MGP and certain of the Company’s related intercompany agreements with MGP or the Operating Partnership. The Company has an approximately 56% controlling interest in MGM China, which owns MGM Grand Paradise, S.A. (“MGM Grand Paradise”), the Macau company that owns and operates the MGM Macau resort and casino and the related gaming subconcession and land concessions, and is in the process of developing an 18 acre site on the Cotai Strip in Macau (“MGM Cotai”). MGM Cotai will be an integrated casino, hotel and entertainment resort with capacity for up to 500 gaming tables and up to 1,500 slots, and featuring approximately 1,400 hotel rooms. The actual number of gaming tables allocated to MGM Cotai will be determined by the Macau government prior to opening, and such allocation is expected to be less than MGM Cotai’s 500 gaming table capacity. The total estimated project budget is $3.3 billion excluding development fees eliminated in consolidation, capitalized interest and land related costs. The Company owns 50% of and manages CityCenter Holdings, LLC (“CityCenter”), located between Bellagio and Monte Carlo. The other 50% of CityCenter is owned by Infinity World Development Corp, a wholly owned subsidiary of Dubai World, a Dubai, United Arab Emirates government decree entity. CityCenter consists of Aria, an integrated casino, hotel and entertainment resort; Mandarin Oriental Las Vegas, a non-gaming boutique hotel; and Vdara, a luxury condominium-hotel. In addition, CityCenter features residential units in the Residences at Mandarin Oriental and Veer. See Note 4 for additional information related to CityCenter. The Company and a subsidiary of Anschutz Entertainment Group, Inc. (“AEG”) each own 42.5% of the Las Vegas Arena Company, LLC (“Las Vegas Arena Company”), the entity which owns the T-Mobile Arena, and Athena Arena, LLC owns the remaining 15%. The Company manages the T-Mobile Arena, which is located on a parcel of the Company’s land between Frank Sinatra Drive and New York-New York, adjacent to the Las Vegas Strip. The T-Mobile Arena is a 20,000 seat venue designed to host world-class events – from mixed martial arts, boxing, basketball and bull riding, to high profile awards shows and top-name concerts. Beginning with the 2017 – 2018 season, the T-Mobile Arena will be the home of the Vegas Golden Knights of the National Hockey League. Additionally, the Company leases the MGM Grand Garden Arena, located adjacent to the MGM Grand Las Vegas, to the Las Vegas Arena Company. See Note 4 for additional information regarding the Company’s investment in the Las Vegas Arena Company. The Company also has a 50% interest in Grand Victoria. Grand Victoria is a riverboat casino in Elgin, Illinois; an affiliate of Hyatt Gaming owns the other 50% of Grand Victoria and also operates the resort. See Note 4 for additional information regarding the Company’s investment in Grand Victoria. A subsidiary of the Company was awarded a casino license to build and operate MGM Springfield in Springfield, Massachusetts. MGM Springfield will be developed on approximately 14 acres of land in downtown Springfield. The Company’s plans for the resort currently include a casino with approximately 2,550 slots and 120 table games including poker; a 250-room hotel; 100,000 square feet of retail and restaurant space; 44,000 square feet of meeting and event space; and a 3,500 space parking garage, with an expected development and construction cost of approximately $960 million, excluding capitalized interest and land related costs. The Company has two reportable segments: domestic resorts and MGM China. See Note 10 for additional information about the Company’s segments.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2 — BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2016 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year. Principles of consolidation. For entities not determined to be a variable interest entity (“VIE”), the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity if it has the direct or indirect ability to control the entities’ activities based upon the terms of the respective entities’ ownership agreements. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets. The Company’s investments in unconsolidated affiliates which are 50% or less owned are accounted for under the equity method when the Company can exercise significant influence over or has joint control of the unconsolidated affiliate. All intercompany balances and transactions are eliminated in 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 VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. Management has determined that MGP is a VIE because the Class A equity investors as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates, cost method investments, 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 observable inputs for similar assets; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 and Level 2 inputs for its long-term debt fair value disclosures (see Note 5); and • Level 2 inputs when measuring the fair value of its interest rate swaps (see Note 6). 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 and losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. As of June 30, 2017 and December 31, 2016, the Company had accrued $47 million and $36 million, respectively, for property and equipment within accounts payable and $33 million and $32 million, respectively, related to construction retention in other long-term liabilities. Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate was 23.5% and 21.6% for the three and six months ended June 30, 2017, respectively. The Company recognizes deferred tax assets, net of applicable reserves, related to tax loss and credit carryforwards and other temporary differences with a future tax benefit to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. The Company has generated significant excess foreign tax credits that 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 that 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. As long as the exemption from Macau’s 12% complementary tax on gaming profits continues and the Company continues to receive distributions from MGM China, the Company expects that it will generate excess foreign tax credits in most years and that most of the excess foreign credits will not be utilized before the exemption expires. On September 7, 2016, MGM Grand Paradise was granted an additional extension of the complementary tax exemption through March 31, 2020, concurrent with the end of the term of its current gaming subconcession. A competitor of MGM Grand Paradise subsequently received an additional extension of its exemption through March 31, 2020, which also runs concurrent with the end of the term of its current gaming concession. Based upon these developments and the uncertainty concerning taxation after the concession renewal process, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond March 31, 2020 and it will thus not be able to credit the Macau Special Gaming Tax in such years, and has factored that assumption into its assessment of the realization of the foreign tax credit deferred tax asset and the measurement of Macau deferred tax liabilities. MGM Grand Paradise’s exemption from the Macau 12% complementary tax on gaming profits does not apply to dividend distributions of such profits to MGM China. However, MGM Grand Paradise has had an agreement with the Macau government to settle the 12% complementary tax that would otherwise be due by its shareholder, MGM China, on distributions of its gaming profits by paying a flat annual payment (“annual fee arrangement”) regardless of the amount of distributable dividends. Such annual fee arrangement was effective for distributions of profits earned through December 31, 2016. MGM China was not subject to the complementary tax on distributions covered by the annual fee arrangement. Annual payments of $2 million were required under the annual fee arrangement. MGM Grand Paradise has requested an extension of this agreement to cover distributions of profits earned through December 31, 2021. However, no assurance can be given that an extension will be granted or that the terms, if granted, will not be less favorable than the prior agreement. Since 2017 earnings are not currently covered by an annual fee arrangement, the Company is providing deferred taxes on such earnings in estimating its annual effective tax rate for 2017. If an extension is granted in 2017, the Company will adjust its annual effective tax rate accordingly. The Company’s assessment of realization of its foreign tax credit deferred tax asset is based on available evidence, including assumptions about future profitability of and distributions from MGM China, as well as its assumption concerning renewals of the exemption from Macau’s 12% complementary tax on gaming profits and future profitability of its U.S. operations. As a result, significant judgment is required in assessing the possible need for and amount of valuation allowance and changes to such assumptions may have a material impact on the amount of the valuation allowance. For example, should the Company in a future period actually receive or be able to assume an additional five-year exemption, an additional valuation allowance would likely need to be provided on some portion or all of the foreign tax credit deferred tax asset, resulting in an increase in the provision for income taxes in such period, and such increase may be material. In addition, a change to forecasts of future profitability of, and distributions from, MGM China could also result in a material change in the valuation allowance with a corresponding impact on the provision for income taxes in such period. Recently issued accounting standards. In 2015 and 2016, the FASB issued the following ASUs related to revenue recognition, effective for fiscal years beginning after December 15, 2017, pursuant to ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”: • ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 provides for a new revenue recognition model which includes a five-step analysis in determining when and how revenue is recognized, including identification of separate performance obligations for each contract with a customer. Additionally, the new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services; • ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” (“ASU 2016-08”) clarifies the implementation guidance on principal versus agent considerations as it relates to ASU 2014-09. ASU 2016-08 provides guidance related to the assessment an entity is required to perform to determine whether the nature of its promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for that good or service to be provided by the other party (that is, the entity is an agent) when another party is involved in providing goods or services to a customer; • ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” (“ASU 2016-10”) clarifies guidance related to identifying performance obligations and licensing implementation guidance as it relates to ASU 2014-09. ASU 2016-10 includes targeted improvements based on input the FASB received from the Transition Resource Group for Revenue Recognition and other stakeholders. It seeks to proactively address areas in which diversity in practice potentially could arise, as well as to reduce the cost and complexity of applying certain aspects of the guidance both at implementation and on an ongoing basis; and • ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” (“ASU 2016-12”) addresses narrow-scope improvements to the guidance on collectability, noncash consideration and completed contracts at transition as it relates to ASU 2014-09. ASU 2016-12 provides for a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The Company is currently assessing the impact that the adoption of the above ASUs related to revenue recognition will have on its consolidated financial statements and footnote disclosures. However, the Company has identified a few significant impacts. Under the new guidance, the Company expects it will no longer be permitted to recognize revenues for goods and services provided to customers for free as an inducement to gamble as gross revenue with a corresponding offset to promotional allowances to arrive at net revenues. The Company expects the majority of such amounts will offset casino revenues. In addition, accounting for Express Comps granted under the Company’s M life Rewards program will also change. Under the new guidance, Express Comps earned by customers through past revenue transactions will be identified as separate performance obligations and recorded as a reduction in gaming revenues when earned at the retail value of such benefits owed to the customer (less estimated breakage). When customers redeem such benefits and the performance obligation is fulfilled by the Company, revenue will be recognized in the department that provides the goods or services (i.e., hotel, food and beverage, or entertainment). In addition, given that M life Rewards is an aspirational loyalty program with multiple customer tiers, which provide certain benefits to tier members, the Company is assessing if such benefits are deemed to be separate performance obligations under the new guidance. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” (“ASU 2016-02”), which replaces the existing guidance in Accounting Standards Codification (“ASC”) 840, “Leases.” ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASU 2016-02 requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use (“ROU”) asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the ROU asset and for operating leases the lessee would recognize a straight-line total lease expense. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force),” (“ASU 2016-15”), effective for fiscal years beginning after December 15, 2017. ASU 2016-15 amends the guidance of ASC 230 on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of ASU 2016-15 is to reduce the diversity in practice that has resulted from the lack of consistent principles, specifically clarifying the guidance on eight cash flow issues. The Company does not expect the adoption of ASU 2016-15 to have a material effect on its consolidated financial statements. In January 2017, the Company adopted ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718),” (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 has separate transition guidance for each element of the new standard. The adoption of ASU 2016-09 did not have a material effect on the Company’s consolidated financial statements and footnote disclosures. In January 2017, the Company adopted ASU No. 2016-17, “Consolidation (Topic 810): Interests Held Through Related Parties that are Under Common Control,” (“ASU 2016-17”). The amendments affect the evaluation of whether to consolidate a VIE in certain situations involving entities under common control. Specifically, the amendments change the evaluation of whether an entity is the primary beneficiary of a VIE for an entity that is a single decision-maker of a variable interest by changing how an entity treats indirect interests in the VIE held through related parties that are under common control with the reporting entity. The guidance in ASU 2016-17 must be applied retrospectively to all relevant periods. The adoption of ASU 2016-17 did not have a material effect on the Company’s consolidated financial statements and footnote disclosures. In January 2017, the Company early adopted ASU No. 2017-04, “Intangibles – disclosures

Borgata Acquisition	NOTE 3 — BORGATA ACQUISITION On August 1, 2016, the Company completed the acquisition of Boyd Gaming Corporation’s (“Boyd Gaming”) ownership interest in Borgata. Following the completion of the acquisition of Boyd Gaming’s interest, MGP acquired Borgata’s real property from the Company and leased back the real property to a subsidiary of the Company. As part of the purchase and sale agreement to acquire Borgata, the Company agreed to pay Boyd Gaming half of any net amount received or utilized by the Company as it relates to the Atlantic City property tax refund owed to Borgata at the time of the transaction. Pursuant to tax court judgments, The City of Atlantic City, New Jersey (“Atlantic City”) owed Borgata property tax refunds of approximately $106 million, plus interest, related to the over-assessment of property values for the 2009-2012 tax years. As a result of funding shortfalls, the City of Atlantic City did not pay the refunds due to Borgata. See Note 7 for information regarding the property tax reimbursement agreement Borgata entered into in February 2017 with the Department of Community Affairs of the State of New Jersey and Atlantic City, and the subsequent receipt of the settlement amount in June 2017. Through the acquisition of Boyd Gaming’s interest in Borgata, the Company obtained 100% of the equity interests in Borgata and therefore consolidated Borgata as of August 1, 2016. The Company recognized 100% of the assets and liabilities of Borgata at fair value at the date of the acquisition. Prior to the acquisition, the Company held a 50% ownership interest in Borgata, which was accounted for under the equity method. Pro forma information.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NOTE 6 — DERIVATIVES AND HEDGING ACTIVITIES The Operating Partnership uses derivative instruments to mitigate the effects of interest rate volatility inherent in its variable rate debt, which could unfavorably impact its future earnings and forecasted cash flows. The Operating Partnership does not use derivative instruments for speculative or trading purposes. The Operating Partnership is party to interest rate swaps that are designated as cash flow hedges to mitigate the interest rate risk inherent in its senior secured term loan B facility. In May 2017, the Operating Partnership amended its outstanding interest rate swap agreements. Under the new agreements the Operating Partnership now pays a weighted average fixed rate of 1.844% on total notional amount of $1.2 billion and the variable rate received will reset monthly to the one-month LIBOR, with no minimum floor. The principal terms at June 30, 2017 are as follows: Effective Date Maturity Date Notional Amount Weighted Average Fixed Rate Fair Value Asset (Liability) (In thousands) May 3, 2017 November 30, 2021 $ 500,000 1.764 % $ 442 May 3, 2017 November 30, 2021 700,000 1.901 % (3,396 ) $ 1,200,000 $ (2,954 ) As of December 31, 2016, the Operating Partnership had interest rate swaps with a notional amount of $500 million outstanding with a weighted average fixed rate of 1.825% and a net unrealized gain of $2 million. Interest rate swaps valued in net unrealized gain positions are recognized as asset balances within “Other long-term assets, net.” Interest rate swaps valued in net unrealized loss positions are recognized as liability balances within “Other long-term obligations.” For the three and six months ended June 30, 2017, the amount recorded in other comprehensive income related to the derivative instruments was a net loss of $3 million and $4 million, respectively. There was no material ineffective portion of the change in fair value of the derivatives. During the three and six months ended June 30, 2017, the Operating Partnership recorded interest expense of $3 million and $5 million, respectively, related to the swap agreements.

Commitments and Contingencies	NOTE 7 — COMMITMENTS AND CONTINGENCIES Borgata property tax reimbursement agreement. On February 15, 2017, Borgata, the Department of Community Affairs of the State of New Jersey and Atlantic City entered into an agreement wherein Borgata was to be reimbursed $72 million as settlement for property tax refunds in satisfaction of New Jersey Tax Court and Superior Court judgments totaling approximately $106 million, plus interest for the 2009-2012 tax years and the settlement of pending tax appeals for the tax years 2013-2015. Those pending tax appeals could potentially have resulted in Borgata being awarded additional refunds due of approximately $65 million. In June 2017, Atlantic City and the State of New Jersey issued bonds and used the proceeds to pay the $72 million settlement in full. The Company recorded the amounts received pursuant to the reimbursement agreement as an offset to general and administrative expenses in the consolidated statements of operations. As required by the purchase and sale agreement to acquire Borgata in August 2016, the Company paid Boyd Gaming half of the settlement amount received by the Company, net of fees and expenses. Amounts paid to Boyd Gaming were recorded in general and administrative expenses in the consolidated statements of operations. NV Energy. In July 2016, the Company filed its notice to exit the fully bundled sales system of NV Energy and now purchases energy, capacity, and/or ancillary services from a provider other than NV Energy. The Company paid an upfront impact payment of $83 million, including $14 million related to CityCenter, in September 2016. Under the terms of the exit agreement, the Company and CityCenter were required to make ongoing payments to NV Energy for non-bypassable rate charges, which primarily relate to each entity’s share of NV Energy’s portfolio of renewable energy contracts which extended through 2040 and each entity’s share of the costs of decommissioning and remediation of coal-fired power plants in Nevada. As of December 31, 2016, the Company recorded an estimate of such liability on a discounted basis of $8 million in “Other accrued liabilities” and $63 million in “Other long-term obligations.” The expense recognized related to the upfront payment and the initial accrual for the liability associated with the non-bypassable charges was recognized within “NV Energy exit expense” in the Company’s consolidated statements of operations. Subsequent accretion of the liability and changes in estimates are recognized within general and administrative expenses in the consolidated statement of operations. In the second quarter of 2017, the terms of the ongoing impact fee obligations were modified. Such modifications included a credit to be applied against future non-bypassable rate charges and substantially shortened the period over which the Company and CityCenter are responsible for such charges, with an end date in 2022. As such, the Company recognized a reduction in its liability for future charges of $41 million with a corresponding credit to NV Energy exit expense. Additionally, CityCenter recorded an $8 million reduction in liability and credit to expense. As of June 30, 2017, the Company has recorded an estimate of its liability on a discounted basis of $9 million in “Other accrued liabilities” and $27 million in “Other long-term obligations.” T-Mobile Arena senior credit facility. The Company is party to a repayment guarantee for the term loan B facility under the Las Vegas Arena Company’s senior credit facility. As of June 30, 2017, the term loan B was $50 million. 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 $250 million, MGP’s senior credit facility limits the amount to $75 million, MGM China’s credit facility limits the amount to $100 million, and MGM National Harbor’s credit facility limits the amount to $30 million. At June 30, 2017, $15 million in letters of credit were outstanding under the Company’s senior credit facility and $39 million in letters of credit were outstanding under MGM China’s credit facility. No letters of credit were outstanding under the MGP senior credit facility and the MGM National Harbor credit facility at June 30, 2017. The amounts of available borrowings under each of the credit facilities are reduced by any outstanding letters of credit. Other litigation. The Company is a party to various legal proceedings, most of which relate to routine matters incidental to its business. Management does not believe that the outcome of such proceedings will have a material adverse effect on the Company’s financial position, results of operations or cash flows.

Segment Reporting [Abstract]
Segment Information	NOTE 10 — SEGMENT INFORMATION The Company’s management views each of its casino resorts as an operating segment. Operating segments are aggregated based on their similar economic characteristics, types of customers, types of services and products provided, the regulatory environments in which they operate and their management and reporting structure. The Company’s principal operating activities occur in two geographic regions: the United States and Macau S.A.R. The Company has aggregated its operations into two reportable segments based on the similar characteristics of the operating segments: domestic resorts and MGM China. The Company’s operations related to investments in unconsolidated affiliates and certain other corporate operations and management services have not been identified as separate reportable segments; therefore, these operations are included in “Corporate and other” in the following segment disclosures to reconcile to consolidated results. The Company’s management utilizes Adjusted Property EBITDA as the primary profit measure for its reportable segments. Adjusted Property EBITDA is a measure defined as Adjusted EBITDA before corporate expense and stock compensation expense related to the Company’s omnibus incentive plan and MGP’s omnibus incentive plan, which are not allocated to the reportable segments or each operating segment, as applicable. MGM China recognizes stock compensation expense related to the MGM China Plan, which is included in the calculation of Adjusted EBITDA for MGM China. Adjusted EBITDA is a measure defined as earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, NV Energy exit expense, preopening and start-up expenses, goodwill impairment charges and property transactions, net.

Related Party Transactions [Abstract]
Related Party Transactions	NOTE 11 — RELATED PARTY TRANSACTIONS MGM China. 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, is party to a brand license agreement with MGM China. MGM China pays a license fee to MGM Branding and Development equal to 1.75% of MGM Macau’s consolidated net revenue, subject to an annual cap of $75 million in 2017 with a 20% increase per annum during the term of the agreement. During the three and six months ended June 30, 2017, MGM China incurred total license fees of $8 million and $17 million, respectively. During the three and six months ended June 30, 2016, MGM China incurred total license fees of $8 million and $16 million, respectively. Such amounts have been eliminated in consolidation. MGM China is party to a development services agreement with MGM Branding and Development where by the latter will provide certain development services to MGM China in connection with future expansion of existing projects and development of future resort gaming projects. Such services are subject to a development fee which is calculated separately for each casino resort property upon commencement of development. For each such property, the fee is 2.625% of project costs, to be paid in installments as certain benchmarks are achieved. Project costs are the total costs incurred for the design, development and construction of the casino, casino hotel, integrated resort and other related sites associated with each project, including all construction costs, fixtures and fittings, signage, gaming and other supplies and equipment and all costs associated with the opening of the business to be conducted at each project but excluding the cost of land, gaming concessions, financing charges and license fees. The development fee for each project is subject to an annual cap of $32 million for each of the years 2017, 2018, and 2019, and the aggregate total development fee cap over the duration of the MGM Cotai project is $70 million. Cumulative payments for the MGM Cotai project have totaled $56 million. During the three and six months ended June 30, 2017, MGM China paid $13 million of fees to MGM Branding and Development related to development services for MGM Cotai. During the three and six months ended June 30, 2016, MGM China paid $12 million of fees to MGM Branding and Development related to development services for MGM Cotai. Such amounts have been eliminated in consolidation. MGP. Pursuant to a master lease agreement by and between the Tenant, which is a subsidiary of the Company and the Landlord, which is a subsidiary of the Operating Partnership, the Tenant has leased MGP’s real estate assets from the Landlord. The master lease has an initial lease term of ten years with the potential to extend the term for four additional five-year terms thereafter at the option of the Tenant. The master lease provides that any extension of its term must apply to all of the real estate under the master lease at the time of the extension. The master lease has a triple-net structure, which requires the Tenant to pay substantially all costs associated with the lease, including real estate taxes, insurance, utilities and routine maintenance, in addition to the base rent. Additionally, the master lease provides the Landlord with a right of first offer with respect to MGM National Harbor and the Company’s development property located in Springfield, Massachusetts, which the Landlord may exercise should the Company elect to sell these properties in the future. The annual rent payments due under the master lease for the first lease year ending March 31, 2017 were $550 million prior to MGP’s acquisition of Borgata’s real property on August 1, 2016. Subsequent to the acquisition, annual rent payments under the master lease increased to $650 million, prorated for the remainder of the first lease year after the Borgata transaction. Rent under the master lease consists of a “base rent” component and a “percentage rent” component. For the second lease year commencing April 1, 2017, annual rent payments due under the master lease are $662 million, which includes base rent of approximately $597 million and percentage rent of approximately $65 million. The base rent includes a fixed annual rent escalator of 2.0% for the second through the sixth lease years (as defined in the master lease). Thereafter, the annual escalator of 2.0% will be subject to the Tenant and, without duplication, the operating subsidiary sublessees of the Tenant, collectively meeting an adjusted net revenue to rent ratio of 6.25:1.00 based on their net revenue from the leased properties subject to the master lease (as determined in accordance with U.S. GAAP, adjusted to exclude net revenue attributable to certain scheduled subleases and, at the Company’s option, reimbursed cost revenue). The percentage rent will initially be a fixed amount for approximately the first six years and will then be adjusted every five years based on the average actual annual net revenues of the Tenant and, without duplication, the operating subsidiary sublessees of the Tenant, from the leased properties subject to the master lease at such time for the trailing five calendar-year period (calculated by multiplying the average annual net revenues, excluding net revenue attributable to certain scheduled subleases and, at the Landlord’s option, reimbursed cost revenue, for the trailing five calendar-year period by 1.4%). During the three and six months ended June 30, 2017, the Company made rent payments to MGP in the amount of $165 million and $328 million, respectively. Pursuant to the master lease, upon an event of default the Landlord may, at its option (i) terminate the master lease, repossess any leased property, relet any leased property to a third party and require that the Tenant pay damages; (ii) require that the Tenant pay to the Landlord rent and other sums payable with interest calculated at the overdue rate provided for in the master lease or terminate the Tenant’s right to possession of the leased property and seek damages; and/or (iii) seek any and all other rights and remedies available under law or in equity. An event of default will be deemed to occur upon certain events, including: (1) the failure by the Tenant to pay rent or other additional charges when due; (2) failure by the Tenant to comply with the covenants set forth in the master lease; (3) certain events of bankruptcy or insolvency with respect to a Tenant or the guarantor; (4) the occurrence of a default under the guaranty of the master lease; (5) the loss or suspension of a material license that causes cessation of gaming activity that would reasonably be expected to have a material adverse effect on the Tenant, the facilities or the leased properties taken as a whole; and (6) the failure of the Company, on a consolidated basis with Tenant, to maintain an EBITDAR to rent ratio (as described in the master lease) of at least 1.10:1.00 for two consecutive test periods. The Company was in compliance with all applicable covenants as of June 30, 2017. All intercompany transactions, including transactions under the master lease, have been eliminated in the Company’s consolidation of MGP. The public ownership of MGP’s Class A shares is recognized as non-controlling interests in the Company’s consolidated financial statements.

Organization Consolidation And Presentation Of Financial Statements [Abstract]
Condensed Consolidating Financial Information	NOTE 12 — CONDENSED CONSOLIDATING FINANCIAL INFORMATION As of June 30, 2017, all of the Company’s principal debt arrangements are guaranteed by each of its material domestic subsidiaries, other than MGP and the Operating Partnership, MGM Grand Detroit, LLC, MGM National Harbor, LLC, Blue Tarp reDevelopment, LLC (the company that will own and operate the Company’s proposed casino in Springfield, Massachusetts), and each of their respective subsidiaries. The Company’s international subsidiaries, including MGM China and its subsidiaries, are not guarantors of such indebtedness. Separate condensed consolidating financial information for the subsidiary guarantors and non-guarantors as of June 30, 2017 and December 31, 2016, and for the three and six months ended June 30, 2017 and 2016 are presented below. Within the Condensed Consolidating Statements of Cash Flows for the six months ended June 30, 2017 and 2016, the Company has presented net changes in intercompany accounts as investing activities if the applicable entities have a net asset in intercompany accounts and as a financing activity if the applicable entities have a net intercompany liability balance. Certain of the Company’s subsidiaries collectively own 76.3% of the Operating Partnership units as of June 30, 2017, and each subsidiary accounts for its respective investment under the equity method within the condensed consolidating financial information presented below. For these subsidiaries, such investment constitutes continuing involvement, and accordingly, the contribution and leaseback of the real estate assets do not qualify for sale-leaseback accounting. The real estate assets that were contributed to and owned by the Operating Partnership, along with the related transactions, are reflected in the balance sheets of the MGM subsidiaries that contributed such assets. In addition, such subsidiaries recognized finance liabilities within “Other long-term obligations” related to rent payments due under the master lease and recognized the related interest expense component of such payments. These real estate assets are also reflected on the balance sheet of the MGP subsidiary that received such assets in connection with the contribution. The condensed consolidating financial information presented below therefore includes the accounting for such activity within the respective columns presented and in the elimination column.

Accounting Policies [Abstract]
Basis of presentation	Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2016 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year.
Principles of consolidation	Principles of consolidation. For entities not determined to be a variable interest entity (“VIE”), the Company consolidates such entities in which the Company owns 100% of the equity. For entities in which the Company owns less than 100% of the equity interest, the Company consolidates the entity if it has the direct or indirect ability to control the entities’ activities based upon the terms of the respective entities’ ownership agreements. For these entities, the Company records a noncontrolling interest in the consolidated balance sheets. The Company’s investments in unconsolidated affiliates which are 50% or less owned are accounted for under the equity method when the Company can exercise significant influence over or has joint control of the unconsolidated affiliate. All intercompany balances and transactions are eliminated in 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 VIE. A VIE is an entity in which either (i) the equity investors as a group, if any, lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance or (ii) the equity investment at risk is insufficient to finance that entity’s activities without additional subordinated financial support. The Company identifies the primary beneficiary of a VIE as the enterprise that has both of the following characteristics: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or receive benefits of the VIE that could potentially be significant to the entity. The Company consolidates its investment in a VIE when it determines that it is its primary beneficiary. For these VIEs, the Company records a noncontrolling interest in the consolidated balance sheets. The Company may change its original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affect the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. The Company performs this analysis on an ongoing basis. Management has determined that MGP is a VIE because the Class A equity investors as a group lack the power through voting or similar rights to direct the activities of such entity that most significantly impact such entity’s economic performance. The Company has determined that it is the primary beneficiary of MGP and consolidates MGP because (i) its ownership of MGP’s single Class B share entitles it to a majority of the total voting power of MGP’s shares, and (ii) the exchangeable nature of the Operating Partnership units owned provide the Company the right to receive benefits from MGP that could potentially be significant to MGP. The Company has recorded
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, cost method investments, 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 observable inputs for similar assets; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 1 and Level 2 inputs for its long-term debt fair value disclosures (see Note 5); and • Level 2 inputs when measuring the fair value of its interest rate swaps (see Note 6).
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 and losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. As of June 30, 2017 and December 31, 2016, the Company had accrued $ 47 million and $36 million, respectively, for property and equipment within accounts payable and $33 million and $32 million, respectively, related to construction retention in other long-term liabilities.
Income tax provision	Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate was 23.5% and 21.6% for the three and six months ended June 30, 2017, respectively. The Company recognizes deferred tax assets, net of applicable reserves, related to tax loss and credit carryforwards and other temporary differences with a future tax benefit to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. The Company has generated significant excess foreign tax credits that 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 that 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. As long as the exemption from Macau’s 12% complementary tax on gaming profits continues and the Company continues to receive distributions from MGM China, the Company expects that it will generate excess foreign tax credits in most years and that most of the excess foreign credits will not be utilized before the exemption expires. On September 7, 2016, MGM Grand Paradise was granted an additional extension of the complementary tax exemption through March 31, 2020, concurrent with the end of the term of its current gaming subconcession. A competitor of MGM Grand Paradise subsequently received an additional extension of its exemption through March 31, 2020, which also runs concurrent with the end of the term of its current gaming concession. Based upon these developments and the uncertainty concerning taxation after the concession renewal process, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond March 31, 2020 and it will thus not be able to credit the Macau Special Gaming Tax in such years, and has factored that assumption into its assessment of the realization of the foreign tax credit deferred tax asset and the measurement of Macau deferred tax liabilities. MGM Grand Paradise’s exemption from the Macau 12% complementary tax on gaming profits does not apply to dividend distributions of such profits to MGM China. However, MGM Grand Paradise has had an agreement with the Macau government to settle the 12% complementary tax that would otherwise be due by its shareholder, MGM China, on distributions of its gaming profits by paying a flat annual payment (“annual fee arrangement”) regardless of the amount of distributable dividends. Such annual fee arrangement was effective for distributions of profits earned through December 31, 2016. MGM China was not subject to the complementary tax on distributions covered by the annual fee arrangement. Annual payments of $2 million were required under the annual fee arrangement. MGM Grand Paradise has requested an extension of this agreement to cover distributions of profits earned through December 31, 2021. However, no assurance can be given that an extension will be granted or that the terms, if granted, will not be less favorable than the prior agreement. Since 2017 earnings are not currently covered by an annual fee arrangement, the Company is providing deferred taxes on such earnings in estimating its annual effective tax rate for 2017. If an extension is granted in 2017, the Company will adjust its annual effective tax rate accordingly. The Company’s assessment of realization of its foreign tax credit deferred tax asset is based on available evidence, including assumptions about future profitability of and distributions from MGM China, as well as its assumption concerning renewals of the exemption from Macau’s 12% complementary tax on gaming profits and future profitability of its U.S. operations. As a result, significant judgment is required in assessing the possible need for and amount of valuation allowance and changes to such assumptions may have a material impact on the amount of the valuation allowance. For example, should the Company in a future period actually receive or be able to assume an additional five-year exemption, an additional valuation allowance would likely need to be provided on some portion or all of the foreign tax credit deferred tax asset, resulting in an increase in the provision for income taxes in such period, and such increase may be material. In addition, a change to forecasts of future profitability of, and distributions from, MGM China could also result in a material change in the valuation allowance with a corresponding impact on the provision for income taxes in such period.
Recently issued accounting standards	Recently issued accounting standards. In 2015 and 2016, the FASB issued the following ASUs related to revenue recognition, effective for fiscal years beginning after December 15, 2017, pursuant to ASU 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date”: • ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” (“ASU 2014-09”) outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. ASU 2014-09 provides for a new revenue recognition model which includes a five-step analysis in determining when and how revenue is recognized, including identification of separate performance obligations for each contract with a customer. Additionally, the new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services; • ASU 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” (“ASU 2016-08”) clarifies the implementation guidance on principal versus agent considerations as it relates to ASU 2014-09. ASU 2016-08 provides guidance related to the assessment an entity is required to perform to determine whether the nature of its promise is to provide the specified good or service itself (that is, the entity is a principal) or to arrange for that good or service to be provided by the other party (that is, the entity is an agent) when another party is involved in providing goods or services to a customer; • ASU 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” (“ASU 2016-10”) clarifies guidance related to identifying performance obligations and licensing implementation guidance as it relates to ASU 2014-09. ASU 2016-10 includes targeted improvements based on input the FASB received from the Transition Resource Group for Revenue Recognition and other stakeholders. It seeks to proactively address areas in which diversity in practice potentially could arise, as well as to reduce the cost and complexity of applying certain aspects of the guidance both at implementation and on an ongoing basis; and • ASU 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” (“ASU 2016-12”) addresses narrow-scope improvements to the guidance on collectability, noncash consideration and completed contracts at transition as it relates to ASU 2014-09. ASU 2016-12 provides for a practical expedient for contract modifications at transition and an accounting policy election related to the presentation of sales taxes and other similar taxes collected from customers. The Company is currently assessing the impact that the adoption of the above ASUs related to revenue recognition will have on its consolidated financial statements and footnote disclosures. However, the Company has identified a few significant impacts. Under the new guidance, the Company expects it will no longer be permitted to recognize revenues for goods and services provided to customers for free as an inducement to gamble as gross revenue with a corresponding offset to promotional allowances to arrive at net revenues. The Company expects the majority of such amounts will offset casino revenues. In addition, accounting for Express Comps granted under the Company’s M life Rewards program will also change. Under the new guidance, Express Comps earned by customers through past revenue transactions will be identified as separate performance obligations and recorded as a reduction in gaming revenues when earned at the retail value of such benefits owed to the customer (less estimated breakage). When customers redeem such benefits and the performance obligation is fulfilled by the Company, revenue will be recognized in the department that provides the goods or services (i.e., hotel, food and beverage, or entertainment). In addition, given that M life Rewards is an aspirational loyalty program with multiple customer tiers, which provide certain benefits to tier members, the Company is assessing if such benefits are deemed to be separate performance obligations under the new guidance. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842),” (“ASU 2016-02”), which replaces the existing guidance in Accounting Standards Codification (“ASC”) 840, “Leases.” ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASU 2016-02 requires a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use (“ROU”) asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the ROU asset and for operating leases the lessee would recognize a straight-line total lease expense. The Company is currently assessing the impact the adoption of ASU 2016-02 will have on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued ASU No. 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (a consensus of the Emerging Issues Task Force),” (“ASU 2016-15”), effective for fiscal years beginning after December 15, 2017. ASU 2016-15 amends the guidance of ASC 230 on the classification of certain cash receipts and payments in the statement of cash flows. The primary purpose of ASU 2016-15 is to reduce the diversity in practice that has resulted from the lack of consistent principles, specifically clarifying the guidance on eight cash flow issues. The Company does not expect the adoption of ASU 2016-15 to have a material effect on its consolidated financial statements. In January 2017, the Company adopted ASU No. 2016-09, “Compensation – Stock Compensation (Topic 718),” (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences, accounting for forfeitures, classification of awards as either equity or liabilities, and classification on the statement of cash flows. ASU 2016-09 has separate transition guidance for each element of the new standard. The adoption of ASU 2016-09 did not have a material effect on the Company’s consolidated financial statements and footnote disclosures. In January 2017, the Company adopted ASU No. 2016-17, “Consolidation (Topic 810): Interests Held Through Related Parties that are Under Common Control,” (“ASU 2016-17”). The amendments affect the evaluation of whether to consolidate a VIE in certain situations involving entities under common control. Specifically, the amendments change the evaluation of whether an entity is the primary beneficiary of a VIE for an entity that is a single decision-maker of a variable interest by changing how an entity treats indirect interests in the VIE held through related parties that are under common control with the reporting entity. The guidance in ASU 2016-17 must be applied retrospectively to all relevant periods. The adoption of ASU 2016-17 did not have a material effect on the Company’s consolidated financial statements and footnote disclosures. In January 2017, the Company early adopted ASU No. 2017-04, “Intangibles – disclosures

Complementary tax rate		12.00%
Tax credit carryforward, description		On September 7, 2016, MGM Grand Paradise was granted an additional extension of the complementary tax exemption through March 31, 2020, concurrent with the end of the term of its current gaming subconcession. A competitor of MGM Grand Paradise subsequently received an additional extension of its exemption through March 31, 2020, which also runs concurrent with the end of the term of its current gaming concession. Based upon these developments and the uncertainty concerning taxation after the concession renewal process, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits for all periods beyond March 31, 2020 and it will thus not be able to credit the Macau Special Gaming Tax in such years, and has factored that assumption into its assessment of the realization of the foreign tax credit deferred tax asset and the measurement of Macau deferred tax liabilities.
