Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	NOTE 1 — ORGANIZATION Organization. MGM Resorts International (the “Company”) is a Delaware corporation that acts largely as a holding company and, through subsidiaries, owns and operates casino resorts. The Company owns and/or 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. Along with local investors, the Company owns and operates MGM Grand Detroit in Detroit, Michigan. The Company owns and operates the following resorts in Mississippi: Beau Rivage in Biloxi and Gold Strike in Tunica. Additionally, subsequent to its acquisition on August 1, 2016, the Company owns and operates the Borgata Hotel Casino & Spa (“Borgata”), located on Renaissance Pointe in the Marina area of Atlantic City, New Jersey. See Note 3 for additional information on the Borgata acquisition. The Company also owns and operates 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. On April 25, 2016, MGM Growth Properties LLC (“MGP”), a subsidiary of the Company, completed its initial public offering (“IPO”) of 57,500,000 of its Class A shares representing limited liability company interests (inclusive of the full exercise by the underwriters of their option to purchase 7,500,000 Class A shares) at an initial offering price of $21 per share. In connection with the IPO, the Company and MGP entered into a series of transactions and several agreements that, among other things, set forth the terms and conditions of the IPO and provide a framework for the Company’s relationship with MGP. MGP is organized as an umbrella partnership REIT (commonly referred to as an “UPREIT”) structure in which substantially all of its assets and substantially all of its businesses are conducted through its operating partnership subsidiary, MGM Growth Properties Operating Partnership LP ( the “Operating Partnership”). MGP contributed the proceeds from the IPO to the Operating Partnership in exchange for 26.7% of the units in 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%. As such, the Company controls MGP through its majority voting rights and consolidates MGP in its financial results. Pursuant to a master contribution agreement by and between the Company, MGP and the Operating Partnership, the Company contributed the real estate assets of The Mirage, Mandalay Bay, Luxor, New York-New York, Monte Carlo, Excalibur, The Park, Gold Strike Tunica, MGM Grand Detroit and Beau Rivage to newly formed subsidiaries and subsequently transferred 100% ownership interest in such subsidiaries to the Operating Partnership in exchange for 73.3% of the Operating Partnership units in the Operating Partnership on the closing date of the IPO. At September 30, 2016, following the completion of the Company’s acquisition of Borgata and the subsequent contribution of Borgata’s real property to MGP, as discussed in Note 11, the Company indirectly owned 76.3% of the Operating Partnership units and MGP’s Class A shareholders owned 23.7% of the Operating Partnership units in the Operating Partnership, which is controlled and consolidated by MGP. The ownership units of the Operating Partnership 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. See Note 5 and Note 11 for additional information related to MGP, the IPO and certain other intercompany agreements and debt financing transactions entered into in connection therewith. The Company acquired an additional 4.95% interest in MGM China Holdings Limited (“MGM China”) on September 1, 2016, which increased its ownership to approximately 56%. See Note 8 for additional information. The Company has a 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 1,500 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 $3.1 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. In April 2016, CityCenter closed the sale of The Shops at The Company and a subsidiary of Anschutz Entertainment Group, Inc. (“AEG”) each own 42.5% of the Las Vegas Arena Company, LLC, the entity which owns the T-Mobile Arena, subsequent to the sale of a 7.5% ownership interest by each of the Company and AEG to Athena Arena, LLC on September 1, 2016. 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, hockey, basketball and bull riding, to high profile awards shows and top-name concerts. T-Mobile Arena commenced operations in April 2016. 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 investments in its unconsolidated affiliates. The Maryland Video Lottery Facility Location Commission has awarded the Company’s subsidiary developing MGM National Harbor a license to build and operate a destination integrated casino, hotel and entertainment resort in Prince George’s County at National Harbor, which is a waterfront development located on the Potomac River just outside of Washington D.C. The expected cost to develop and construct MGM National Harbor is approximately $1.4 billion, excluding capitalized interest and land related costs. The Company expects the resort to include a casino with over 3,300 slots and approximately 160 table games including poker; a 300-room hotel with luxury spa and rooftop pool; 93,100 square feet of high‑end branded retail and fine and casual dining; a 3,000-seat theater venue; 50,000 square feet of meeting and event space; and a 4,700-space parking garage. 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 3,000 slots and 100 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 3,375 space parking garage, with an expected development and construction cost of approximately $865 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 2015 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. 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. The Company identifies entities for which control is achieved through means other than voting rights and to determine which business enterprise is the primary beneficiary of variable interest entities (“VIEs”). 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. 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 As of September 30, 2016, MGP had total assets of $9.5 billion, primarily related to its real estate investments, and total liabilities of $3.9 billion, primarily related to its indebtedness. For entities not determined to be VIEs, 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. All intercompany balances and transactions are eliminated in consolidation. 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. Property and equipment. The Company had accrued $37 million and $17 million for property and equipment as of September 30, 2016 and December 31, 2015, respectively, within “Accounts payable” and $31 million and $44 million as of September 30, 2016 and December 31, 2015, respectively, related to construction retention in “Other long-term obligations.” 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 (8.7)% and (1.3)% for the three and nine months ended September 30, 2016, 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. As of December 31, 2015, the scheduled future reversal of existing U.S. federal taxable temporary differences exceeded the scheduled future reversal of existing U.S. federal deductible temporary differences. Consequently, the Company no longer applies a valuation allowance against its domestic deferred tax assets other than its foreign tax credit deferred tax asset. 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. The current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, and 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 concluded that it can no longer assume that MGM Grand Paradise will be entitled to additional exemption periods beyond the end of the extension recently granted. Thus, for all periods beyond March 31, 2020, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits 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. This change resulted in a reduction in the valuation allowance against the foreign tax credit deferred tax asset in the amount of $169 million and an increase in the Macau deferred tax liability in the amount of $36 million with a corresponding reduction in the provision for income taxes of $133 million during the three and nine months ended September 30, 2016. Due to improvements in its U.S. operations, the Company has generated U.S. operating profits for the past seven consecutive quarters and as of June 30, 2016 no longer had cumulative U.S. losses in recent years. Consequently, during the quarter ended June 30, 2016 the Company began to rely on future U.S. source operating income in assessing future foreign tax credit realization during the 10-year foreign tax credit carryover period. This change resulted in a reduction in the valuation allowance and a corresponding reduction in the provision for income taxes during the nine months ended September 30, 2016 of $85 million. As a result of the change in assumption concerning the complementary tax exemption renewal and the reliance on U.S. operating income in assessing future foreign tax credit realization, the Company now projects that it will record a deferred tax asset for foreign tax credits, net of valuation allowance, of approximately $360 million as of December 31, 2016. 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 August 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” (“ASU 2015-14”), which defers the effective date of Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”) to the fiscal year, and interim periods within the year, beginning on or after December 15, 2017. 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. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. 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. The Company is currently assessing the impact that adoption of ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” (“ASU 2016-08”), effective for the fiscal years beginning after December 15, 2017. ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations as it relates to ASU 2014-09. The amendment relates 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. The Company is currently assessing the impact that adoption of ASU 2016-08 will have on its consolidated financial statements and footnote disclosures. In May 2016, the FASB issued Accounting Standards Update No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” (“ASU 2016-10”), effective for fiscal years beginning after December 15, 2017. ASU 2016-10 clarifies guidance related to identifying performance obligations and licensing implementation guidance as it relates to ASU 2014-09. The update 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. In May 2016, the FASB issued Accounting Standards Update No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” (“ASU 2016-12”), effective for fiscal years beginning after December 15, 2017. 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. The amendments provide 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. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842),” (“ASU 2016-02”), which replaces the existing guidance in Accounting Standard 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 that adoption of ASU 2016-02 will have on its consolidated financial statements and footnote disclosures. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Compensation – Stock Compensation (Topic 718),” (“ASU 2016-09”), effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company is currently assessing the impact that adoption of ASU 2016-09 will have on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued Accounting Standard Update 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 is currently assessing the impact that adoption of ASU 2016-15 will have on its consolidated financial statements. In October 2016, the FASB issued Accounting Standards Update No. 2016-17, “Consolidation (Topic 810): Interests Held Through Related Parties that are Under Common Control, (“ASU 2016-17”), effective for fiscal years beginning after December 15, 2016. 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 Company is currently assessing the impact the adoption of ASU 2016-17 will have on its consolidated financial statements and footnote disclosures.

Borgata Acquisition

Borgata Acquisition	9 Months Ended

Business Combinations [Abstract]
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. See Note 11 for additional information. Cash paid to Boyd Gaming as of September 30, 2016 for its interest in Borgata was $594 million. As part of the purchase and sale agreement, the Company agreed to pay Boyd Gaming half of any amount received or utilized by the Company as it relates to the Atlantic City tax refund owed to Borgata at the time of the transaction. Pursuant to tax court judgments, the City of Atlantic City, New Jersey owes 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 has not paid the refunds due to Borgata and therefore, Borgata has withheld its current property tax obligations in satisfaction of the tax court judgment. Borgata applied $23 million of such credits as of September 30, 2016. The Company has accrued as contingent consideration related to the acquisition the amount to be paid to Boyd Gaming related to the property tax refunds expected to be realized by Borgata. During 2014, Borgata and the City of Atlantic City entered into a settlement agreement covering the 2011-2014 tax years, but that agreement has since been terminated. On October 25, 2016, the Atlantic City government released a plan to finance a portion of its potential tax refund obligation to Borgata, based on the assumption of a settlement with Borgata, subject to approval by the state of New Jersey. On November 1, 2016, the state of New Jersey rejected the plan. The Company has not agreed to a settlement amount and has no agreement to settle its judgments or pending tax. 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. The fair value of the equity interests of Borgata was determined by the transaction price and equaled approximately $1.2 billion. The carrying value of the Company’s equity method investment was significantly less than its share of the fair value of Borgata at the acquisition date, resulting in a $430 million gain on the acquisition. Under the acquisition method, the fair value was allocated to the assets acquired and liabilities assumed in the transaction. The allocation of fair value for substantially all of the assets and liabilities is preliminary and may be adjusted up to one year after the acquisition. Specifically, the Company is finalizing valuation work related to intangible assets and determining property tax credits expected to be realized by Borgata. The following table sets forth the preliminary allocation at August 1, 2016 (in thousands): Fair value of assets acquired and liabilities assumed: Current assets $ 111,542 Property and equipment and other long-term assets 1,373,567 Goodwill 385,483 Trademarks and trade name 91,000 Customer relationships 18,000 Current liabilities (122,743 ) Long-term debt (583,187 ) Deferred taxes (14,715 ) Other long-term obligations (51,894 ) $ 1,207,053 As discussed above, the Company recognized the identifiable intangible assets of Borgata at fair value. The trademarks and trade name and customer relationship intangible assets did not have historical cost bases at Borgata. The estimated fair values of the intangible assets were preliminarily determined using methodologies under the income approach based on significant inputs that were not observable. Unfavorable lease liability. The Company has assumed the liability of a series of ground leases for a total of approximately 20 acres of land on which the Borgata employee parking garage, public space expansion, rooms expansion, modified surface parking lot, beer garden and outdoor pool reside. The Company recorded an unfavorable lease liability of $1 million in “Current liabilities” and $47 million in “Other long-term obligations” for the excess contractual lease obligations over the market value of the leases, which will be amortized on a straight-line basis over the term of the lease contracts through December 2070. Both a market and income approach using Level 2 and Level 3 inputs were utilized to determine the fair value of these leases. Deferred taxes. The Company recorded an additional net deferred tax liability of $92 million, of which $83 million and $9 million was recorded to income tax expense and goodwill, respectively. The net deferred tax liability represents the excess of the financial reporting amounts of the net assets of Borgata over their respective basis under U.S. and New Jersey tax law expected to be applied to taxable income in the periods such differences are expected to be realized. Consolidated results. Borgata’s net revenue for the period from August 1, 2016 through September 30, 2016 was $151 million, operating income was $23 million and net income was $11 million . Pro forma information. The operating results for Borgata are included in the accompanying consolidated statements of operations from the date of acquisition. The following unaudited pro forma consolidated financial information for the Company has been prepared assuming the Company’s acquisition of its controlling interest has occurred as of January 1, 2015 and excludes the transaction gain recognized by the Company. 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 January 1, 2015.

During the nine months ended September 30, 2016, CityCenter recognized a gain on the sale of Crystals of $392 million and the Company recognized a $397 million gain, which included $196 million representing its 50% share of the gain recorded by CityCenter and $201 million representing the reversal of certain basis differences. The basis differences primarily related to other-than-temporary impairment charges recorded on the Company’s investment in CityCenter that were allocated to Crystals’ building assets. As of December 31, 2015, assets held for sale related to Crystals of $668 million and associated liabilities of Crystals were classified as current within the summarized balance sheet information. CityCenter distributions. In March 2016, a $90 million distribution was declared in accordance with CityCenter’s annual distribution policy and in April 2016, CityCenter declared a $990 million special distribution in connection with the Crystals sale. The Company’s $540 million share of such distributions was paid in May 2016.

At December 31, 2015, the amount available under the Company’s revolving senior credit facility was less than current maturities related to the Company’s term loan credit facilities and senior notes. The Company excluded from the December 31, 2015 current portion of long-term debt the amount available for refinancing under its revolving credit facility. Senior credit facility. In April 2016, the Company entered into an amended and restated credit agreement comprised of a $1.25 billion revolving facility and a $250 million term loan A facility. The revolving facility and the term loan A facility initially bore interest at LIBOR plus 2.75% for the first six months, and thereafter the interest rate is determined by reference to a total net leverage ratio pricing grid which results in an interest rate of LIBOR plus 1.75% to 2.75%. Both the term loan A facility and the revolving facility will mature in April 2021 . The term loan A facility is subject to amortization of principal in equal quarterly installments (commencing with the fiscal quarter ended March 31, 2017), with 5.0% of the initial aggregate principal amount of the term loan A facility to be payable each year. No amounts have been drawn on the revolving credit facility. The Company incurred a loss on early retirement of its prior credit facility of approximately $28 million recorded in “Other, net” in the consolidated statements of operations. At September 30, 2016, the interest rate on the term loan A facility was 3.27%. The amended and restated credit agreement contains representations and warranties, customary events of default, and positive, negative and financial covenants, including that the Company maintain compliance with a maximum total net leverage ratio, a maximum first lien net leverage ratio and a minimum interest coverage ratio. The Company was in compliance with its credit agreement covenants at September 30, 2016. The amended and restated credit agreement is secured by (i) a mortgage on the real properties comprising the MGM Grand Las Vegas and the Bellagio, (ii) a pledge of substantially all existing and future personal property of the subsidiaries of the Company that own the Mandatory prepayments MGM Growth Properties senior credit facility. In April 2016, the Operating Partnership entered into a credit agreement comprised of a $300 million senior secured term loan A facility, a $1.85 billion senior secured term loan B facility, and a $600 million senior secured revolving credit facility. The revolving credit facility and term loan A facility initially bore interest at LIBOR plus 2.75% for the first six months, and thereafter the interest rate is determined by reference to a total net leverage ratio pricing grid which results in an interest rate of LIBOR plus 2.25% to 2.75%. The term loan B facility initially bore interest at LIBOR plus 3.25%, with a LIBOR floor of 0.75%. The term loan B facility was originally issued at 99.75% to initial lenders. On October 26, the term loan B facility was re-priced at par and will bear interest at LIBOR plus 2.75%, with a LIBOR floor of 0.75%, which represents a 50 basis point reduction compared to the prior rate. In addition, the Operating Partnership will receive a further reduction in pricing to LIBOR plus 2.50%, with a LIBOR floor of 0.75% so long as it achieves minimum corporate family ratings of Ba3/BB-. All other principal provisions of the existing credit facility remain unchanged. The revolving credit facility and the term loan A facility will mature in 2021 and the term loan B facility will mature in 2023. The term loan facilities are subject to amortization of principal in equal quarterly installments, with 5.0% of the initial aggregate principal amount of the term loan A facility and 1.0% of the initial aggregate principal amount of the term loan B facility to be payable each year. The Company permanently repaid $4 million and $8 million of the term loan A facility in the three and nine months ended September 30, 2016, respectively, in accordance with the scheduled amortization. The Company permanently repaid $5 million and $9 million of the term loan B facility in the three and nine months ended September 30, 2016, respectively, in accordance with the scheduled amortization. At September 30, 2016, the term loan A facility had an amount outstanding of $293 million with an interest rate of 3.27% and the term loan B facility had an amount outstanding of $1.84 billion with an interest rate of 4.0%. No amounts have been drawn on the revolving credit facility. The credit agreement contains customary representations and warranties, events of default, and positive, negative and financial covenants, including that the Operating Partnership maintain compliance with a maximum senior secured net debt to adjusted total assets ratio, maximum total net debt to adjusted assets ratio and a minimum interest coverage ratio. The Operating Partnership was in compliance with its credit agreement covenants at September 30, 2016. MGM China credit facility. At September 30, 2016, the MGM China credit facility consisted of $1.55 billion of term loans and a $1.45 billion revolving credit facility, which bear interest at a fluctuating rate per annum based on HIBOR plus a margin that ranges between 1.375% and 2.5% based on MGM China’s leverage ratio. The MGM China credit facility matures in April 2019, with scheduled amortization payments of the term loans beginning in October 2017. The MGM China credit facility is secured by MGM Grand Paradise’s interest in the Cotai land use right, and MGM China, MGM Grand Paradise and their guarantor subsidiaries have granted a security interest in substantially all of their assets to secure the facility. The outstanding balance at September 30, 2016 was comprised of $1.56 billion of term loans and $206 million drawn on the revolving credit facility. At September 30, 2016, the weighted average interest rate on the term loans was 2.27% and the interest rate on the revolving credit facility was 2.25%. The MGM China 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. MGM China was in compliance with its credit facility covenants at September 30, 2016. MGM National Harbor credit facility. In January 2016, MGM National Harbor, LLC, the Company’s subsidiary developing and constructing MGM National Harbor, entered into a credit agreement consisting of a $100 million revolving credit facility and a $425 million delayed draw term loan facility, the total amount of which was funded as of September 30, 2016. No amounts have been drawn on the revolving credit facility. In connection with any future revolver draws in excess of $25 million prior to the opening date of the project the Company is required to make a matching cash equity contribution in MGM National Harbor. The revolving and term loan facilities bear interest at LIBOR plus an applicable rate determined by the Company’s total leverage ratio (2.25% as of September 30, 2016). The term loan and revolving facilities are scheduled to mature in January 2021 and the term loan facilities are subject to scheduled amortization payments on the last day of each calendar quarter beginning the fourth full fiscal quarter following the opening date of MGM National Harbor, initially in an amount equal to 1.25% of the aggregate principal balance and increasing to 1.875% and 2.50% of the aggregate principal balance on the last day of the twelfth and sixteenth full fiscal quarters, respectively. At September 30, 2016, the interest rate on the term loan A was 2.78%. The credit agreement is secured by a leasehold mortgage on MGM National Harbor and substantially all of the existing and future property of MGM National Harbor. Mandatory prepayments will be required upon the occurrence of certain events, including sales of certain assets, casualty events and the incurrence of certain additional indebtedness, subject to certain exceptions and reinvestment rights. In addition, to the extent MGM National Harbor generates excess cash flow (as defined in the credit agreement), a percentage of such excess cash flow (ranging from 0% to 50% based on a total leverage ratio) will be required to be used to prepay the term loan facilities commencing with the fiscal year ending 2017. The credit agreement contains customary representations and warranties, events of default, and positive, negative and financial covenants, including that MGM National Harbor, LLC and its restricted subsidiaries maintain compliance with a maximum total leverage ratio and a minimum interest coverage ratio. In addition, borrowings under the credit agreement are subject to a customary “in balance test” (as defined in the credit agreement), which requires that, as of the date of determination prior to the opening date, the available funds (including resources that may be available from the Company) are equal to or exceed the remaining costs for MGM National Harbor. MGM National Harbor was in compliance with its credit agreement covenants at September 30, 2016. Senior notes.

The Company and CityCenter are 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 extend through 2040 and each entity’s share of the costs of decommissioning and remediation of coal-fired power plants in Nevada. As of September 30, 2016, the Company recorded an estimate of such liability on a discounted basis of $6 million in “Other accrued liabilities” and $64 million in “Other long-term obligations.” The expense recognized related to the upfront payment and the initial accrual for the non-bypassable charges liability has been recognized within “NV Energy exit expense” in the accompanying consolidated statements of operations.

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 within the regions in which they operate: 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 Omnibus 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, preopening and start-up expenses, NV Energy exit expense, gain on Borgata transaction, goodwill impairment charges, and property transactions, net.

Pursuant to a master lease agreement by and between a subsidiary of the Company (the “Tenant”) and a subsidiary of the Operating Partnership (the “Landlord”), the Tenant has leased the contributed 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 the Company’s development properties located in National Harbor, Maryland and Springfield, Massachusetts, which the Landlord may exercise should the Company elect to sell these properties in the future. Subsequent to the Company completing its acquisition of Borgata on August 1, 2016, MGP acquired Borgata’s real property from a subsidiary of the Company in exchange for MGP’s assumption of $545 million of indebtedness and the issuance of 27.4 million Operating Partnership units to a subsidiary of the Company. In connection with this transaction, the Tenant and Landlord entered into an amendment to the master lease to include the Borgata real property. The annual rent payments due under the master lease 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 acquisition. Rent under the master lease consists of a “base rent” component and a “percentage rent” component. For the first year, the base rent will represent 90% of the initial total rent payments due under the master lease and the percentage rent will represent 10% of the initial total rent payments due under the master lease. 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 nine months ended September 30, 2016, the Company made rent payments to the Landlord in the amount of $154 million and $255 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, beginning with the test periods ending December 31, 2016 and March 31, 2017. Pursuant to a corporate services agreement, the Company provides MGP and its subsidiaries with financial, administrative and operational support services, including accounting and finance support, human resources support, legal and regulatory compliance support, insurance advisory services, internal audit services, governmental affairs monitoring and reporting services, information technology support, construction services, and various other support services. The Company is reimbursed for all costs it incurs directly related to providing the services thereunder. Due to the Company’s continuing involvement with MGP and the Operating Partnership, the contribution and leaseback of the real estate described above does not qualify for sale-leaseback accounting. In addition, all intercompany transactions, including transactions under the corporate services agreement and 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 September 30, 2016, all of the Company’s principal debt arrangements were guaranteed by each of its material domestic subsidiaries, other than MGP, 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 financial information for the subsidiary guarantors and non-guarantors as of September 30, 2016 and December 31, 2015, and for the three and nine months ended September 30, 2016 and 2015 are presented below. Within the Condensed Consolidating Statements of Cash Flows for the nine months ended September 30, 2016 and 2015, 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 (“OPCOs”) collectively own 76.3% of the Operating Partnership units as of September 30, 2016, and each subsidiary accounts for its respective investment under the equity method within the condensed consolidating financial information presented below. At 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 in connection with the IPO, 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. For all periods prior to the commencement of the Master Lease arrangement, the condensed consolidating financial information set forth herein has been retrospectively adjusted to conform prior periods to the current presentation, as the transactions occurred between entities, which are considered businesses, under common control. Accordingly, the real estate assets and associated operations in all periods prior to the IPO date were reclassified to conform to the current organizational structure, and are reflected in the MGP subsidiary that currently has legal title to such assets. The September 30, 2016 condensed consolidating balance sheets presented below for the Guarantor Subsidiaries and MGP includes corrections that the Company has determined to be immaterial, which were made in order to properly reflect the recognition of the OPCOs investment in the initial proceeds received by the Operating Partnership in connection with the second quarter 2016 IPO transaction. As a result of the Borgata transaction in the third quarter of 2016, the OPCOs investment balances reflect the difference between the carrying value of their investment immediately prior to the Borgata transaction and their percentage share of the underlying equity of the Operating Partnership immediately after the Borgata transaction.

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended

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 2015 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. 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. The Company identifies entities for which control is achieved through means other than voting rights and to determine which business enterprise is the primary beneficiary of variable interest entities (“VIEs”). 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. 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 As of September 30, 2016, MGP had total assets of $9.5 billion, primarily related to its real estate investments, and total liabilities of $3.9 billion, primarily related to its indebtedness. For entities not determined to be VIEs, 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. All intercompany balances and transactions are eliminated in consolidation.
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.
Property and equipment	Property and equipment. The Company had accrued $ 37 million and $17 million for property and equipment as of September 30, 2016 and December 31, 2015, respectively, within “Accounts payable” and $31 million and $44 million as of September 30, 2016 and December 31, 2015, respectively, related to construction retention in “Other long-term obligations.”
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 (8.7)% and (1.3)% for the three and nine months ended September 30, 2016, 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. As of December 31, 2015, the scheduled future reversal of existing U.S. federal taxable temporary differences exceeded the scheduled future reversal of existing U.S. federal deductible temporary differences. Consequently, the Company no longer applies a valuation allowance against its domestic deferred tax assets other than its foreign tax credit deferred tax asset. 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. The current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, and 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 concluded that it can no longer assume that MGM Grand Paradise will be entitled to additional exemption periods beyond the end of the extension recently granted. Thus, for all periods beyond March 31, 2020, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits 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. This change resulted in a reduction in the valuation allowance against the foreign tax credit deferred tax asset in the amount of $169 million and an increase in the Macau deferred tax liability in the amount of $36 million with a corresponding reduction in the provision for income taxes of $133 million during the three and nine months ended September 30, 2016. Due to improvements in its U.S. operations, the Company has generated U.S. operating profits for the past seven consecutive quarters and as of June 30, 2016 no longer had cumulative U.S. losses in recent years. Consequently, during the quarter ended June 30, 2016 the Company began to rely on future U.S. source operating income in assessing future foreign tax credit realization during the 10-year foreign tax credit carryover period. This change resulted in a reduction in the valuation allowance and a corresponding reduction in the provision for income taxes during the nine months ended September 30, 2016 of $85 million. As a result of the change in assumption concerning the complementary tax exemption renewal and the reliance on U.S. operating income in assessing future foreign tax credit realization, the Company now projects that it will record a deferred tax asset for foreign tax credits, net of valuation allowance, of approximately $360 million as of December 31, 2016. 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 August 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2015-14, “Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,” (“ASU 2015-14”), which defers the effective date of Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”) to the fiscal year, and interim periods within the year, beginning on or after December 15, 2017. 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. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. 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. The Company is currently assessing the impact that adoption of ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. In March 2016, the FASB issued Accounting Standards Update No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net),” (“ASU 2016-08”), effective for the fiscal years beginning after December 15, 2017. ASU 2016-08 clarifies the implementation guidance on principal versus agent considerations as it relates to ASU 2014-09. The amendment relates 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. The Company is currently assessing the impact that adoption of ASU 2016-08 will have on its consolidated financial statements and footnote disclosures. In May 2016, the FASB issued Accounting Standards Update No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing,” (“ASU 2016-10”), effective for fiscal years beginning after December 15, 2017. ASU 2016-10 clarifies guidance related to identifying performance obligations and licensing implementation guidance as it relates to ASU 2014-09. The update 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. In May 2016, the FASB issued Accounting Standards Update No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients,” (“ASU 2016-12”), effective for fiscal years beginning after December 15, 2017. 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. The amendments provide 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. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842),” (“ASU 2016-02”), which replaces the existing guidance in Accounting Standard 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 that adoption of ASU 2016-02 will have on its consolidated financial statements and footnote disclosures. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, “Compensation – Stock Compensation (Topic 718),” (“ASU 2016-09”), effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The Company is currently assessing the impact that adoption of ASU 2016-09 will have on its consolidated financial statements and footnote disclosures. In August 2016, the FASB issued Accounting Standard Update 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 is currently assessing the impact that adoption of ASU 2016-15 will have on its consolidated financial statements. In October 2016, the FASB issued Accounting Standards Update No. 2016-17, “Consolidation (Topic 810): Interests Held Through Related Parties that are Under Common Control, (“ASU 2016-17”), effective for fiscal years beginning after December 15, 2016. 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 Company is currently assessing the impact the adoption of ASU 2016-17 will have on its consolidated financial statements and footnote disclosures.

Complementary tax rate		12.00%
Period exempted from complementary tax, second exemption period granted		5 years
Complementary tax exemption expiration date		Dec. 31, 2016
Third exemption period from complementary tax assumed based on third exemption period granted to a competitor		5 years
Tax credit carryforward, description		The current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, and 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 concluded that it can no longer assume that MGM Grand Paradise will be entitled to additional exemption periods beyond the end of the extension recently granted. Thus, for all periods beyond March 31, 2020, the Company has assumed that MGM Grand Paradise will pay the Macau 12% complementary tax on gaming profits 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.

Leasing arrangement description of rent					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%).
