Additionally , the Company owns and operates MGM National Harbor in Prince George’s County, Maryland, which opened on December 8, 2016. On April 25, 2016, MGM Growth Properties LLC (“MGP”), a consolidated 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 are owned by, 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 Operating Partnership units representing limited partner interests in the Operating Partnership. The general partner of the Operating Partnership is also a subsidiary of MGP. 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%. Pursuant to a master contribution agreement entered into in connection with the IPO 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. In addition, on August 1, 2016, the Company completed its acquisition of Borgata and subsequently contributed Borgata’s real estate assets to MGP, as discussed in Note 4. As a result of the Borgata transaction, as discussed in Note 20, the Company’s indirect ownership in the Operating Partnership units increased to 76.3% and MGP’s Class A shareholders’ ownership interest in Operating Partnership units was reduced to 23.7%. 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. See Note 10 and Note 19 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 14 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 $3.3 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. In April 2016, CityCenter closed the sale of The Shops at Crystals (“Crystals”), a retail, dining and entertainment district. See Note 7 and Note 19 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, 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. Effective January 1, 2016, the Company leases the MGM Grand Garden Arena, located adjacent to the MGM Grand Las Vegas, to the Las Vegas Arena Company. See Note 7 and Note 13 for additional information regarding the Company’s investment in the Las Vegas Arena Company. In addition, the Company owns and operates The Park, a dining and entertainment district, which opened in April 2016 and which connects to T-Mobile Arena, New York-New York, Monte Carlo and the Park Theater, a 5,200 seat entertainment venue which opened in December 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 7 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 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 18 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 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 MGP’s 26.7% interest in the Operating Partnership prior to the Borgata transaction and 23.7% interest subsequent to the Borgata transaction as noncontrolling interest in the Company’s consolidated financial statements. As of December 31, 2016, on a consolidated basis 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. Management’s use of estimates. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. These principles require the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates, 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 10; • Level 2 inputs when measuring the fair value of its interest rate swaps. See Note 11; • Level 2 and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed during the Borgata transaction. See Note 4; • Level 2 and Level 3 inputs when measuring the impairment of goodwill related to the MGM China reporting unit. See Note 8; and • Level 3 inputs when assessing the fair value of its investment in Grand Victoria. See Note 7 Cash and cash equivalents. Cash and cash equivalents include investments and interest bearing instruments with maturities of 90 days or less at the date of acquisition. Such investments are carried at cost, which approximates market value. Book overdraft balances resulting from the Company’s cash management program are recorded as accounts payable or construction payable as applicable. Accounts receivable and credit risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of casino accounts receivable. The Company issues credit to approved casino customers and gaming promoters following background checks and investigations of creditworthiness. At December 31, 2016, 47% of the Company’s casino receivables at its domestic resorts were due from customers residing in foreign countries and 9% of the Company’s casino receivables related to MGM China. Business or economic conditions or other significant events in these countries could affect the collectability of such receivables. Accounts receivable are typically non-interest bearing and are initially recorded at cost. Accounts are written off when management deems the account to be uncollectible. Recoveries of accounts previously written off are recorded when received. An estimated allowance for doubtful accounts is maintained to reduce the Company’s receivables to their net carrying amount, which approximates fair value. The allowance is estimated based on both a specific review of customer accounts as well as historical collection experience and current economic and business conditions. Management believes that as of December 31, 2016, no significant concentrations of credit risk existed for which an allowance had not already been recorded. Inventories. Inventories consist primarily of food and beverage, retail merchandise and operating supplies, and are stated at the lower of cost or net realizable value. Cost is determined primarily using the average cost method for food and beverage and operating supplies. Cost for retail merchandise is determined using the cost method. Property and equipment. Property and equipment are stated at cost. A significant amount of the Company’s property and equipment was acquired through business combinations and therefore recognized at fair value at the acquisition date. Gains or losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. As of December 31, 2016 and 2015, the Company had accrued $36 million and $17 million for property and equipment within accounts payable and $32 million and $44 million related to construction retention accrued in other long-term liabilities, respectively. Property and equipment are generally depreciated over the following estimated useful lives on a straight-line basis: Buildings and improvements 20 to 40 years Land improvements 10 to 20 years Furniture and fixtures 3 to 20 years Equipment 3 to 15 years The Company evaluates its property and equipment and other long-lived assets for impairment based on its classification as held for sale or to be held and used. Several criteria must be met before an asset is classified as held for sale, including that management with the appropriate authority commits to a plan to sell the asset at a reasonable price in relation to its fair value and is actively seeking a buyer. For assets held for sale, the Company recognizes the asset at the lower of carrying value or fair market value less costs to sell, as estimated based on comparable asset sales, offers received, or a discounted cash flow model. For assets to be held and used, the Company reviews for impairment whenever indicators of impairment exist. The Company then compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset, typically measured using a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs. All recognized impairment losses, whether for assets held for sale or assets to be held and used, are recorded as operating expenses. Capitalized interest. The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. When no debt is incurred specifically for a project, interest is capitalized on amounts expended on the project using the weighted-average cost of the Company’s outstanding borrowings. Capitalization of interest ceases when the project is substantially complete or development activity is suspended for more than a brief period. Investments in and advances to unconsolidated affiliates. The Company has investments in unconsolidated affiliates accounted for under the equity method. Under the equity method, carrying value is adjusted for the Company’s share of the investees’ earnings and losses, amortization of certain basis differences, as well as capital contributions to and distributions from these companies. Distributions in excess of equity method earnings are recognized as a return of investment and recorded as investing cash inflows in the accompanying consolidated statements of cash flows. The Company classifies operating income and losses as well as gains and impairments related to its investments in unconsolidated affiliates as a component of operating income or loss, as the Company’s investments in such unconsolidated affiliates are an extension of the Company’s core business operations. The Company evaluates its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying value of its investment may have experienced an “other-than-temporary” decline in value. If such conditions exist, the Company compares the estimated fair value of the investment to its carrying value to determine if an impairment is indicated and determines whether the impairment is “other-than-temporary” based on its assessment of all relevant factors, including consideration of the Company’s intent and ability to retain its investment. The Company estimates fair value using a discounted cash flow analysis based on estimated future results of the investee and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. See Note 7 and Note 17 for results of the Company’s review of its investment in certain of its unconsolidated affiliates. Goodwill and other intangible assets. Goodwill represents the excess of purchase price over fair market value of net assets acquired in business combinations. Goodwill and indefinite-lived intangible assets must be reviewed for impairment at least annually and between annual test dates in certain circumstances. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. No impairments were indicated or recorded as a result of the annual impairment review for goodwill and indefinite-lived intangible assets in 2016 and 2014. An impairment of goodwill related to the MGM China reporting unit was recorded as a result of the annual impairment review in 2015. See Note 8. Accounting guidance provides entities the option to perform a qualitative assessment of goodwill (commonly referred to as “step zero”) in order to determine whether further impairment testing is necessary. In performing the step zero analysis the Company considers macroeconomic conditions, industry and market considerations, current and forecasted financial performance, entity-specific events, and changes in the composition or carrying amount of net assets of reporting units. In addition, the Company takes into consideration the amount of excess of fair value over carrying value determined in the last quantitative analysis that was performed, as well as the period of time that has passed since the last quantitative analysis. If the step zero analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would proceed to a two-step quantitative analysis. Under the two-step quantitative analysis, goodwill for relevant reporting units is tested for impairment using a discounted cash flow analysis based on the estimated future results of the Company’s reporting units discounted using market discount rates and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. If the carrying value of the reporting unit exceeds its fair value, an indication of impairment exists and the Company must proceed to measure an impairment loss, if any. To measure an impairment loss, the implied fair value of a reporting unit’s goodwill is compared to the carrying value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to its assets and liabilities and the amount remaining, if any, is the implied fair value of goodwill. If the implied fair value of goodwill is less than its carrying value then it must be written down to its implied fair value. License rights are tested for impairment using a discounted cash flow approach, and trademarks are tested for impairment using the relief-from-royalty method. If the fair value of an indefinite-lived intangible asset is less than its carrying amount, an impairment loss is recognized equal to the difference. Revenue recognition and promotional allowances. Casino revenue is the aggregate net difference between gaming wins and losses, with liabilities recognized for funds deposited by customers before gaming play occurs (“casino front money”) and for chips in the customers’ possession (“outstanding chip liability”). Hotel, food and beverage, entertainment, retail and other operating revenues are recognized as services are performed and goods are provided. Advance deposits on rooms and advance ticket sales are recorded as accrued liabilities until services are provided to the customer. Gaming revenues are recognized net of certain sales incentives, including discounts and points earned in point-loyalty programs. The retail value of hotel rooms, food and beverage, and other services furnished to guests without charge is included in gross revenue and then deducted as promotional allowances. The estimated cost of providing promotional allowances is primarily included in casino expenses as follows: Year Ended December 31, 2016 2015 2014 (In thousands) Rooms $ 120,369 $ 112,313 $ 115,463 Food and beverage 283,598 279,041 295,667 Entertainment, retail and other 39,611 39,388 39,673 $ 443,578 $ 430,742 $ 450,803 Gaming promoters. A significant portion of the high-end (“VIP”) gaming volume at MGM Macau is generated through the use of gaming promoters, also known as junket operators. These operators introduce VIP gaming players to MGM Macau, assist these customers with travel arrangements, and extend gaming credit to these players. VIP gaming at MGM Macau is conducted by the use of special purpose nonnegotiable gaming chips. Gaming promoters purchase these nonnegotiable chips from MGM Macau and in turn sell these chips to their players. The nonnegotiable chips allow MGM Macau to track the amount of wagering conducted by each gaming promoter’s clients in order to determine VIP gaming play volume, or rolling chip turnover, which is the amount of nonnegotiable chips wagered and lost. In exchange for the gaming promoters’ services, MGM Macau compensates the gaming promoters through revenue-sharing arrangements and rolling chip turnover-based commissions. The estimated portion of the gaming promoter commissions that represent amounts passed through to VIP customers is recorded as a reduction of casino revenue, and the estimated portion retained by the gaming promoter for its compensation is recorded as casino expense. Reimbursed costs. The Company recognizes costs reimbursed pursuant to management services as revenue in the period it incurs the costs. Reimbursed costs related primarily to the Company’s management of CityCenter. Loyalty programs. The Company’s primary loyalty program is “M life Rewards” and is available to patrons at most of the Company’s domestic resorts and CityCenter. Members may earn points and/or Express Comps for their gaming play which can be redeemed at restaurants, box offices or the M life Rewards front desk at participating properties. Points may also be redeemed for free slot play on participating machines. The Company records a liability based on the points earned multiplied by the redemption value, less an estimate for points not expected to be redeemed, and records a corresponding reduction in casino revenue. Customers also earn Express Comps based on their gaming play which can be redeemed for complimentary goods and services, including hotel rooms, food and beverage, and entertainment. The Company records a liability for the estimated costs of providing goods and services for Express Comps based on the Express Comps earned multiplied by a cost margin, less an estimate for Express Comps not expected to be redeemed and records a corresponding expense in the casino department. MGM Macau also has a loyalty program, whereby patrons earn rewards that can be redeemed for complimentary services, including hotel rooms, food and beverage, and entertainment. Advertising. The Company expenses advertising costs the first time the advertising takes place. Advertising expense, which is generally included in general and administrative expenses, was $171 million for 2016 and $156 million for 2015 and 2014. Corporate expense. Corporate expense represents unallocated payroll, aircraft costs, professional fees and various other expenses not directly related to the Company’s casino resort operations. In addition, corporate expense includes the costs associated with the Company’s evaluation and pursuit of new business opportunities, which are expensed as incurred. Preopening and start-up expenses. Preopening and start-up costs, including organizational costs, are expensed as incurred. Costs classified as preopening and start-up expenses include payroll, outside services, advertising, and other expenses related to new or start-up operations. Property transactions, net. The Company classifies transactions such as write-downs and impairments, demolition costs, and normal gains and losses on the sale of assets as “Property transactions, net.” See Note 17 for a detailed discussion of these amounts. Redeemable noncontrolling interest. In 2015, MGM National Harbor issued non-voting economic interests in MGM National Harbor (“Interests”) to noncontrolling interest parties, for a total purchase price of $6 million. In 2016, MGM National Harbor issued Interests to noncontrolling interest parties for a purchase price of $47 million. Net income attributable to noncontrolling interests includes $0.5 million relating to redeemable noncontrolling interests for the year ended December 31, 2016. The Interests provide for annual preferred distributions by MGM National Harbor to the noncontrolling interest parties based on a percentage of its annual net gaming revenue (as defined in the MGM National Harbor operating agreement). Such distributions will begin within ninety days after the end of the fiscal year in which the opening date of MGM National Harbor occurs, and after the end of each subsequent fiscal year. Also, beginning on the third anniversary of the last day of the calendar quarter in which the opening date of MGM National Harbor occurs (and on each subsequent anniversary thereof) the noncontrolling interest parties will each have the ability to require MGM National Harbor to purchase all or a portion of their Interests for a purchase price based on a contractually agreed upon formula. Certain noncontrolling interest parties each have the right to sell back all or a portion of their Interests prior to such date if MGM National Harbor were to guarantee or grant liens to secure any indebtedness of the Company or its affiliates other than the indebtedness of MGM National Harbor. The Company has recorded the Interests as “Redeemable noncontrolling interests” in the mezzanine section of the accompanying consolidated balance sheets and not stockholders’ equity because their redemption is not exclusively in the Company’s control. Interests are initially accounted for at fair value. Subsequently, the Company will recognize changes in the redemption value as they occur and adjust the carrying amount of the redeemable noncontrolling interests to equal the maximum redemption value, provided such amount does not fall below the initial carrying value, at the end of each reporting period. The Company records any changes caused by such an adjustment in retained earnings or accumulated deficit. Additionally the carrying amount of the redeemable noncontrolling interests is adjusted for annual preferred distributions, with changes caused by such adjustments recorded within net income (loss) attributable to noncontrolling interests. Income (loss) per share of common stock. The table below reconciles basic and diluted income (loss) per share of common stock. Diluted net income (loss) attributable to common stockholders includes adjustments for redeemable noncontrolling interests and the potentially dilutive effect on the Company’s equity interests in MGP and MGM China due to shares outstanding under their respective stock compensation plans. Diluted weighted-average common and common equivalent shares includes adjustments for potential dilution of share-based awards outstanding under the Company’s stock compensation plan. Year Ended December 31, 2016 2015 2014 Numerator: (In thousands) Net income (loss) attributable to MGM Resorts International $ 1,101,440 $ (447,720 ) $ (149,873 ) Adjustment related to redeemable noncontrolling interests (28 ) — — Net income (loss) available to common stockholders - basic 1,101,412 (447,720 ) (149,873 ) Potentially dilutive effect due to MGP Omnibus Plan (40 ) — — Potentially dilutive effect due to MGM China Share Option Plan (11 ) — (340 ) Net income (loss) attributable to common stockholders - diluted $ 1,101,361 $ (447,720 ) $ (150,213 ) Denominator: Weighted-average common shares outstanding basic 568,134 542,873 490,875 Potential dilution from share-based awards 5,183 — — Weighted-average common and common equivalent shares - diluted 573,317 542,873 490,875 Antidilutive share-based awards excluded from the calculation of diluted earnings per share 4,207 18,276 19,254 The weighted-average common shares outstanding for the year ended December 31, 2015 included the weighted average impact of the $300 million 4.25% convertible senior notes issued in June 2011 and the $1.15 billion 4.25% convertible senior notes issued in April 2010 from the date of their conversion on April 15, 2015. The weighted-average impact of the assumed conversion of the convertible senior notes was excluded from the calculation of diluted earnings per share for the years ended December 31, 2015 and 2014 as their effect would be antidilutive. See Note 10 for additional information. Currency translation. The Company translates the financial statements of foreign subsidiaries that are not denominated in U.S. dollars. Balance sheet accounts are translated at the exchange rate in effect at each balance sheet date. Income statement accounts are translated at the average rate of exchange prevailing during the period. Translation adjustments resulting from this process are recorded to other comprehensive income (loss). Derivative financial instruments. The Company reflects all derivative instruments at fair value as either assets or liabilities. For derivative instruments that are designated and qualify as hedging instruments, the effective portion of the gain or loss on the cash flow hedge instruments is recorded as a component of accumulated other comprehensive income. Any ineffective portion of a derivative’s change in fair value is immediately recognized within net income. As of December 31, 2016, all of the Company’s derivative financial instruments are interest rate swap agreements which have been designated as cash flow hedges and qualify for hedge accounting. Accumulated other comprehensive income (loss). Comprehensive income (loss) includes net income (loss) and all other non-stockholder changes in equity, or other comprehensive income (loss). Elements of the Company’s accumulated other comprehensive income are reported in the accompanying consolidated statements of stockholders’ equity. The following table summarizes the changes in the accumulated balance of other comprehensive income: Currency translation adjustments Cash Flow Hedges Other Total (In thousands) Balance, December 31, 2014 $ 12,319 $ — $ 672 $ 12,991 Other comprehensive income (loss) before reclassifications 3,727 — (672 ) 3,055 Amounts reclassified from accumulated other comprehensive income — — — — Other comprehensive income (loss), net of tax 3,727 — (672 ) 3,055 Other comprehensive income (loss) attributable to noncontrolling interest (2,024 ) — — (2,024 ) Balance, December 31, 2015 14,022 — — 14,022 Other comprehensive income (loss) before reclassifications (2,680 ) 1,521 1,074 (85 ) Amounts reclassified from accumulated other comprehensive income — 358 — 358 Other comprehensive income (loss), net of tax (2,680 ) 1,879 1,074 273 Other comprehensive income (loss) attributable to noncontrolling interest 1,203 (445 ) — 758 Balance, December 31, 2016 $ 12,545 $ 1,434 $ 1,074 $ 15,053 Recently issued accounting standards. In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40).” The guidance is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The Company adopted this guidance prospectively at the beginning of the fourth quarter of 2016. The adoption of this guidance did not have an effect on the Company’s financial condition, results of operations, cash flows, or disclosures. 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),” 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),” 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,” 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,” 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 as discussed above. 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 as outlined above 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, 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 will need to assess if such benefits are deemed to be separate perf

Business Combinations [Abstract]
Borgata Transaction	NOTE 4 — BORGATA TRANSACTION 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 19 for additional information. As part of the purchase and sale agreement, 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”) 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 $33 million of such credits as of December 31, 2016. After taking into account contingent consideration paid related to property tax refunds realized by Borgata, cash paid to Boyd Gaming for its interest in Borgata was $604 million. 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 has been finalized as of December 31, 2016. The following table sets forth the finalized allocation at December 31, 2016 (in thousands): Fair value of assets acquired and liabilities assumed: Current assets $ 112,221 Property and equipment and other long-term assets 1,373,567 Goodwill 386,892 Trade name 83,000 Customer list 22,000 Current liabilities (122,743 ) Long-term debt (583,187 ) Deferred taxes (12,124 ) Other long-term obligations (51,894 ) $ 1,207,732 As discussed above, the Company recognized the identifiable intangible assets of Borgata at fair value. The trade name and customer relationship intangible assets did not have historical cost bases at Borgata. The estimated fair values of the intangible assets were 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 11 acres of land on which the Borgata employee parking garage, public space expansion, rooms expansion, and modified surface parking lot. 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 $89 million, of which $82 million and $7 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 December 31, 2016 was $348 million, operating income was $39 million and net income was $8 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.

In April 2016, CityCenter closed the sale of Crystals for approximately $1.1 billion. During the year ended December 31, 2016, CityCenter recognized a gain on the sale of Crystals of $400 million and the Company recognized a $401 million gain, which included $200 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 previously recorded on the Company’s investment in CityCenter that were allocated to Crystals’ building assets. CityCenter distribution. 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. In April 2015, CityCenter declared a special distribution of $400 million, of which the Company received its 50% share of $200 million. CityCenter litigation settlement. During the first quarter of 2015, CityCenter recognized a $160 million gain as a result of the final resolution of its construction litigation and related settlements, of which the Company recorded $80 million, its 50% share of the gain. CityCenter credit facility. CityCenter’s senior secured credit facility consisted of a $75 million revolving credit facility, maturing in October 2018 and a $1.2 billion term loan B facility maturing in October 2020. CityCenter used cash on hand to permanently repay $266 million of the term loan B facility during 2016. On January 27, 2017, CityCenter completed an amendment to re-price its $1.2 billion term loan B senior credit facility and re-price and extend its $75 million revolving facility. The term loan B facility was re-priced at par and will now 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 and a 25 basis point reduction compared to the prior LIBOR floor . The revolving facility was re-priced at LIBOR plus 2.00%, which represents a 175 basis point reduction compared to the prior rate . The revolving facility was also extended to July 2020. All other principal provisions of the existing credit facility remain unchanged. Borgata As discussed in Note 4, the Company acquired Boyd Gaming’s ownership interest in Borgata on August 1, 2016, and therefore began to consolidate Borgata beginning on that date. Prior thereto, the Company’s investment in Borgata was accounted for under the equity method. Grand Victoria At December 31, 2015, the Company reviewed the carrying value of its Grand Victoria investment for impairment due to a greater than anticipated decline in operating results due in part to a continued loss of market share to video gaming terminals, as well as a decrease in forecasted cash flows compared to the prior forecast. The Company used a blended discounted cash flow analysis and guideline public company method to determine the estimated fair value from a market participant’s viewpoint. Key assumptions included in the discounted cash flow analysis were estimates of future cash flows including outflows for capital expenditures, a long-term growth rate of 2% and a discount rate of 10.5%. Key assumptions in the guideline public company method included business enterprise value multiples selected based on the range of multiples in Grand Victoria’s peer group. As a result of the analysis, the Company determined that it was necessary to record an other-than-temporary impairment charge of $17 million at December 31, 2015, based on an estimated fair value of $123 million for the Company’s 50% interest. The Company performed a sensitivity analysis surrounding its long-term growth rate assumption and noted that if a long-term growth rate of 1.5% had been used, the resulting estimated fair value of the Company’s 50% interest in Grand Victoria would have been approximately $120 million. The Company intends to, and believes it will be able to, retain its investment in Grand Victoria; however, due to the extent of the shortfall and the Company’s assessment of the uncertainty of fully recovering its investment, the Company has determined that the impairment was other-than-temporary. At June 30, 2014, the Company reviewed the carrying value of its Grand Victoria investment for impairment due to a greater than anticipated decline in operating results and loss of market share due to the proliferation of video gaming terminals in the Illinois market, as well as a decrease in forecasted cash flows compared to the prior forecast. The Company used a blended discounted cash flow analysis and guideline public company method to determine the estimated fair value from a market participant’s viewpoint. Key assumptions included in the discounted cash flow analysis were estimates of future cash flows including outflows for capital expenditures, a long-term growth rate of 2% and a discount rate of 10.5%. Key assumptions in the guideline public company method included business enterprise value multiples selected based on the range of multiples in Grand Victoria’s peer group. As a result of the analysis, the Company determined that it was necessary to record an other-than-temporary impairment charge of $29 million at June 30, 2014, based on an estimated fair value of $140 million for the Company’s 50% interest. Las Vegas Arena Company, LLC Athena Arena transaction. On September 1, 2016, the Company and AEG each sold a 7.5% membership interest in the Las Vegas Arena Company, LLC to Athena Arena, LLC. As a result of this transaction, the Company received $15 million in proceeds and recorded a $3 million gain in “Property transactions, net”. Arena financing. In September 2014, a subsidiary of Las Vegas Arena Company entered into a senior secured credit facility to finance construction of the T-Mobile Arena. In connection with this senior credit facility, MGM Resorts International and AEG each entered into a repayment guarantee for the term loan B (which is subject to increases and decreases in the event of rebalancing of the principal amount of indebtedness between the term loan A and term loan B facilities). As of December 31, 2016, the senior secured credit facility consisted of a $150 million term loan A and a $50 million term loan B. The senior secured credit facility matures in September 2019. The senior secured credit facility is secured by substantially all the assets of the Las Vegas Arena Company, and contains certain financial covenants which became applicable upon the opening of the T-Mobile Arena in April 2016. I n accordance with the Las Vegas Arena Company’s senior secured credit facility, the Company and AEG contributed equal amounts totaling $175 million for construction, all of which had been contributed as of December 31, 2015. See Note 13 for discussion of the Company’s joint and several completion and repayment guarantees related to the Las Vegas Arena Company. Silver Legacy Silver Legacy sale. As discussed in Note 5, the Company closed the sale of its 50% interest in Silver Legacy on November 23, 2015, received proceeds of $58 million, and recorded a gain of $20 million. The Company’s investment in Silver Legacy was not classified as discontinued operations because the Company concluded that the sale would not have a major effect on the Company’s operations or its financial results and it did not represent a disposal of a major geographic segment or product line.

The results of Crystals, including the gain on sale recognized in 2016, are classified as discontinued operations in the summarized results of operations for all periods presented. Basis Differences The Company’s investments in unconsolidated affiliates do not equal the Company’s share of venture-level equity due to various basis differences. Basis differences related to depreciable assets are being amortized based on the useful lives of the related assets and liabilities and basis differences related to non–depreciable assets, such as land and indefinite-lived intangible assets, are not being amortized.

See Note 4 for goodwill recognized in connection with the Borgata transaction. The Company recognized goodwill resulting from its acquisition of a controlling interest in MGM China in 2011. During the fourth quarter of 2015, the Company conducted its annual impairment tests of goodwill by reviewing each of its reporting units, including its MGM China reporting unit. The step one goodwill analysis of the MGM China reporting unit indicated the fair value was less than its carrying value by 4%. The decrease in fair value resulted from a decrease in forecasted cash flows based on then current market conditions and a sustained decline in the enterprise value multiples of the MGM China reporting unit as well as the multiples of the reporting unit’s peer group. As a result of the indication of impairment from its step one analysis, the Company performed a step two impairment analysis to measure the impairment loss. As such, the Company determined the fair values of all assets of the MGM China reporting unit, including its separately identifiable intangible assets. The fair values of each of the separately identifiable intangible assets exceeded their respective carrying values by a significant amount, leading to a lower implied fair value of goodwill. Therefore, the Company recorded a $1.5 billion non-cash impairment charge to reduce the historical carrying value of goodwill related to the MGM China reporting unit to its implied fair value. The carrying value of goodwill related to the MGM China reporting unit as of December 31, 2015 following the impairment charge was $1.4 billion. Indefinite-lived intangible assets. The Company’s indefinite-lived intangible assets consist primarily of development rights in Detroit, trademarks and license rights, of which $210 million consists of trademarks and trade names related to the Mandalay Resort Group acquisition and $83 million related to the Borgata trade name. MGM Grand Paradise gaming subconcession. Pursuant to the agreement dated June 19, 2004 between MGM Grand Paradise and Sociedade de Jogos de Macau, S.A., a gaming subconcession was acquired by MGM Grand Paradise for the right to operate casino games of chance and other casino games for a period of 15 years commencing on April 20, 2005. The Company cannot provide any assurance that the gaming subconcession will be extended beyond the original terms of the agreement; however, management believes that the gaming subconcession will be extended, given that the Cotai land concession agreement with the government extends significantly beyond the gaming subconcession. As such, the Company is amortizing the gaming subconcession intangible asset on a straight-line basis over the term of the Cotai land concession, ending in January 2038. MGM Macau land concession. MGM Grand Paradise entered into a contract with the Macau government to use the land under MGM Macau commencing from April 6, 2006. The land use right has an initial term through April 6, 2031, subject to renewal for additional periods. The land concession intangible asset is amortized on a straight-line basis over the remaining initial contractual term. Customer lists. The Company recognized an intangible asset related to MGM China’s customer lists, which was amortized on an accelerated basis over its estimated useful life of five years. The MGM China customer list intangible asset became fully amortized in 2016. The Company recognized an intangible asset related to the Borgata customer list, which is amortized on an accelerated basis over its estimated useful life of two years and five months. Gaming licenses. The Company was granted a license to operate a casino in Maryland. The consideration paid to the State of Maryland for the license fee of $22 million is considered a finite-lived intangible asset that is amortized on a straight-line basis over a period of 15 years, beginning in December 2016, when the casino started operations. The Company was granted a license to operate a casino in Massachusetts. The consideration paid to the State of Massachusetts for the license fee of $85 million is considered a finite-lived intangible asset that will be amortized over a period of 15 years beginning upon the opening of the casino resort. Other. The Company’s other finite–lived intangible assets consist primarily of lease acquisition costs amortized over the life of the related leases, and certain license rights amortized over their contractual life. Total amortization expense related to intangible assets was $180 million, $199 million and $232 million for 2016, 2015, and 2014, respectively. Estimated future amortization is as follows: Years ending December 31, (In thousands) 2017 $ 183,414 2018 177,758 2019 178,081 2020 178,081 2021 178,081 Thereafter 2,782,171 $ 3,677,586

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. Interest expense, net consisted of the following: Year Ended December 31, 2016 2015 2014 (In thousands) Total interest incurred $ 814,731 $ 862,377 $ 846,321 Interest capitalized (119,958 ) (64,798 ) (29,260 ) $ 694,773 $ 797,579 $ 817,061 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 bear interest 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 December 31, 2016, the interest rate on the term loan A facility was 3.02%. 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 December 31, 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 MGM Grand Las Vegas and the Bellagio; and (iii) a pledge of the equity or limited liability company interests of the entities that own MGM Grand Las Vegas and the Bellagio. Mandatory prepayments of the credit facilities 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. 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 term loan B facility was originally issued at 99.75% to initial lenders. The revolving credit facility and term loan A facility bear interest 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%. On October 26, 2016 the term loan B facility was re-priced at par and bore interest at LIBOR plus 2.75%, with a LIBOR floor of 0.75%, which represented a 50 basis point reduction compared to the prior rate. In addition, the Operating Partnership received a further reduction in pricing to LIBOR plus 2.50%, with a LIBOR floor of 0.75% as a result of it achieving a minimum corporate family rating of Ba3/BB- in February 2017. 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 $8 million of the term loan A facility and $9 million of the term loan B facility for the year ended December 31, 2016. At December 31, 2016, the term loan A facility had an amount outstanding of $293 million with an interest rate of 3.52% and the term loan B facility had an amount outstanding of $1.84 billion with an interest rate of 3.52%. No amounts were drawn on the revolving credit facility as of December 31, 2016. 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 December 31, 2016. MGM China credit facility. At December 31, 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 December 31, 2016 was comprised of $1.56 billion of term loans and $374 million drawn on the revolving credit facility. At December 31, 2016, the weighted average interest rate on the term loans was 2.73% and the interest rate on the revolving credit facility was 2.50%. 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 December 31, 2016. In February 2017, the MGM China credit facility was amended to increase the maximum total leverage ratio to 6.00 to 1.00 through December 31, 2017, declining to 5.50 to 1.00 at March 31, 2018, 5.00 to 1.00 at June 30, 2018 and 4.50 to 1.00 at September 30, 2018 and thereafter. MGM National Harbor credit agreement. In January 2016, MGM National Harbor, LLC entered into a credit agreement consisting of a $100 million revolving credit facility and a $425 million term loan facility. The revolving and term loan facilities bear interest at LIBOR plus an applicable rate determined by MGM National Harbor, LLC’s total leverage ratio (2.25% as of December 31, 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. The outstanding balance at December 31, 2016 was comprised of $425 million of term loans and $25 million drawn on the revolving credit facility. At December 31, 2016, the interest rate on the term loan was 3.02% and the interest rate on the revolving credit facility was 2.90%. 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. MGM National Harbor, LLC was in compliance with its credit agreement covenants at December 31, 2016. Senior Notes. On August 19, 2016, the Company issued $500 million in aggregate principal amount of 4.625% senior notes due 2026 for net proceeds of $493 million. I n September 2016, t he Company used the net proceeds, together with cash on hand, to redeem the $743 million outstanding aggregate principal amount of its 7.625% senior notes due 2017. T he Company incurred a loss on early retirement of the 7.625% senior notes of approximately $16 million recorded in “Other, net” in the consolidated statements of operations. In connection with the closing of the IPO, on May 25, 2016 (the “Redemption Date”) the Company redeemed for cash all $1.23 billion aggregate principal amount of its outstanding 7.5% senior notes due 2016 and 10% senior notes due 2016 in accordance with the terms of the applicable indenture. The Company incurred a loss on early retirement of such notes of approximately $22 million recorded in “Other, net” in the consolidated statements of operations. In 2015, the Company repaid its $875 million 6.625% senior notes at maturity. The senior notes are unsecured and otherwise rank equally in right of payment with the Company’s existing and future senior indebtedness. The senior notes are effectively subordinated to the Company’s existing and future secured obligations, primarily consisting of its senior credit facility, to the extent of the value of the assets securing such obligations. Bridge Facilities. In connection with the Borgata transaction in August 2016, the Company borrowed $545 million under certain bridge facilities, which were subsequently contributed to the Operating Partnership. The Operating Partnership repaid the bridge facilities with a combination of cash on hand and a draw down on its revolving credit facility, which it subsequently refinanced with proceeds from its offering of its 4.5% senior notes due 2026. In connection with the closing of the IPO, the Company borrowed $4.0 billion under certain bridge facilities, the proceeds of which were used to repay its outstanding obligations under its prior senior credit facility and were used to repay its 7.5% senior notes due 2016 and its 10% senior notes due 2016 on the Redemption Date. The bridge facilities were subsequently assumed by the Operating Partnership pursuant to the master contribution agreement. The Operating Partnership repaid the bridge facilities with a combination of proceeds from its financing transactions described in Note 1 and the proceeds from the IPO. MGM Growth Properties senior notes. On August 12, 2016, the Operating Partnership and MGP Finance Co-Issuer, Inc. issued $500 million in aggregate principal amount of 4.5% senior notes due 2026 for net proceeds of $492 million. On April 20, 2016, a subsidiary of the Operating Partnership issued $1.05 billion in aggregate principal amount of 5.625% senior notes due 2024 and on April 25, 2016, the Operating Partnership entered into a supplemental indenture through which it assumed the obligations under the notes from such subsidiary (which merged into the Operating Partnership on such date) . Convertible senior notes. In April 2015, holders of substantially all of the $1.45 billion in aggregate principal amount of 4.25% convertible senior notes elected to convert the notes into approximately 78 million shares of the Company’s common stock. The notes were converted at 53.83 shares of common stock per $1,000 principal amount, which is equivalent to a conversion price of approximately $18.58 per share. In addition, the Company settled the capped call transactions entered into in connection with the initial issuance of $1.15 billion aggregate principal amount of notes and received approximately 6 million shares from such financial institutions. Such shares received in connection with the capped call transactions were subsequently retired. Maturities of long-term debt.

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	NOTE 11 — 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. In December 2016, the Operating Partnership entered into interest rate swap agreements to mitigate the interest rate risk inherent in its senior secured term loan B facility. These interest rate swaps are designated as cash flow hedges and have a notional value of $500 million and mature on November 30, 2021. The weighted average fixed rate paid is 1.825%, and the variable rate received resets monthly to the one-month LIBOR subject to a minimum rate of 0.75%. The following table summarizes the fair value and the presentation in the Company’s balance sheet: Location on Balance Sheet December 31, 2016 (In thousands) Interest rate swaps - cash flow hedges Other long-term assets, net $ 1,879 As of December 31, 2016, all of the interest rate swaps were valued in net unrealized gain positions and recognized as asset balances within “Other long-term assets, net.” For the year ended December 31, 2016, the amount recorded in other comprehensive income related to the gain on derivative instruments was $2 million. For the year ended December 31, 2016, there was no ineffective portion of the change in fair value derivatives. During the fourth quarter of 2016, the Company recorded interest expense of $0.4 million related to the swap agreements. Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on our variable-rate debt. During the twelve months beginning January 1, 2017, the Company estimates that $4 million will be reclassified as an increase to interest expense. In January 2017, the Operating Partnership entered into additional interest rate swap agreements through November 2021 with a total $700 million notional amount to pay a fixed rate of 1.964%, and the variable rate received resets monthly to the one-month LIBOR, subject to a minimum rate of 0.75%, in order to mitigate the interest rate risk inherent in its senior secured term loan B facility.

The Company recognizes future tax benefits to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied.

Absent this exemption, “Net income attributable to MGM Resorts International” would have decreased by $25 million in 2016, and “Net loss attributable to MGM Resorts International” would have increased by $25 million in 2015 and net income per share (diluted) would have decreased by $0.04 in 2016 and net loss per share (diluted) would have increased by $0.04 in 2015. Non-gaming operations remain subject to the Macau complementary tax. MGM Grand Paradise had at December 31, 2016 a complementary tax net operating loss carryforward of $593 million resulting from non-gaming operations that will expire if not utilized against non-gaming income in years 2017 through 2019. 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 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 until December 31, 2016. MGM China was not subject to the complementary tax on distributions it received during the covered period as a result of the annual fee arrangement. Annual payments of $2 million were required under the annual fee arrangement. The $2 million annual payments for 2016 and 2015 were accrued and a corresponding provision for income taxes was recorded in each year. MGM Grand Paradise intends to file for an extension of this agreement in the first quarter of 2017. 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. The Company repatriated $53 million and $304 million of foreign earnings and profits in 2016 and 2015, respectively. At December 31, 2016, there were approximately $363 million of unrepatriated foreign earnings and profits, all of which the Company anticipates will be repatriated without the incurrence of additional U.S. income tax expense due to creditable foreign taxes associated with such earnings and profits. Such foreign taxes consist of the Macau Special Gaming Tax, which the Company believes qualifies as a tax paid in lieu of an income tax that is creditable against U.S. income taxes. Accordingly, no deferred tax liability had been recorded for those earnings. The Company had foreign tax credit carryovers of $2.8 billion as of December 31, 2016 which will expire as follows: $731 million in 2022; $976 million in 2023; $786 million in 2024; and $331 million in 2025. The foreign tax credit carryovers are subject to valuation allowance as described further below. For state income tax purposes, the Company had Illinois, New Jersey, and Michigan net operating loss carryforwards of $93 million, $166 million, and $77 million at December 31, 2016, respectively, which equates to deferred tax assets after federal tax effect and before valuation allowance, of $5 million, $3 million, and $3 million, respectively. The Illinois net operating loss carryforwards will expire if not utilized by 2021 through 2026. The New Jersey net operating loss carryforwards will expire if not utilized by 2029 through 2036. The Michigan net operating loss carryforwards will expire if not utilized by 2022 through 2024. The Company recorded a valuation allowance of $2.5 billion against the $2.8 billion foreign tax credit deferred tax asset at December 31, 2016. In addition, there was a $3 million valuation allowance, after federal effect, provided on certain state deferred tax assets, a valuation allowance of $71 million on certain Macau deferred tax assets, and a valuation allowance of $2 million on Hong Kong net operating losses because the Company believes these assets do not meet the “more likely than not” criteria for recognition. The foreign tax credits 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. 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 will thus not be able to credit the Macau Special Gaming Tax in such years, and has factored that assumption into the assessment of the realization of the foreign tax credit deferred tax asset. This change resulted in a reduction in the valuation allowance against the foreign tax credit deferred tax asset in the amount of $169 Due to improvements in its U.S. operations, the Company has generated U.S. operating profits for the past eight 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 of $85 A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits is as follows: Year Ended December 31, 2016 2015 2014 (In thousands) Gross unrecognized tax benefits at January 1 $ 13,724 $ 31,143 $ 106,246 Gross increases - prior period tax positions — — 1,626 Gross decreases - prior period tax positions (3,375 ) (14,158 ) (43,098 ) Gross increases - current period tax positions 3,677 1,222 5,066 Settlements with taxing authorities — (2,408 ) (38,697 ) Lapse in Statutes of Limitations — (2,075 ) — Gross unrecognized tax benefits at December 31 $ 14,026 $ 13,724 $ 31,143 The total amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate was $9 million and $8 The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company accrued less than $1 million in interest related to unrecognized tax benefits at December 31, 2016 and 2015. No amounts were accrued for penalties as of either date. Income tax expense for the years ended December 31, 2016, 2015 and 2014 includes interest benefit and expense related to unrecognized tax benefits as follows: less than $1 million expense in 2016, $4 million benefit in 2015, and $13 million benefit in 2014. The Company files income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions, and foreign jurisdictions, although the income taxes paid in foreign jurisdictions are not material. As of December 31, 2016, the Company is no longer subject to examination of its U.S. consolidated federal income tax returns filed for years ended prior to 2010. During 2016, the IRS opened an examination of the Company’s 2014 U.S. consolidated federal income tax return and notified the Company that it would open an examination of the 2014 income tax return of CityCenter Holdings, LLC, an unconsolidated affiliate treated as a partnership for income tax purposes. During 2015, the Company received final approval from the Joint Committee on Taxation of the results of the IRS examination of the 2009 tax year and agreed to all IRS adjustments to the 2010 and 2011 tax years of CityCenter Holdings, LLC. The Company received a refund of $16 million of taxes and associated interest in connection with the settlement of these examinations, which are now considered settled for financial accounting purposes. During 2014, the Company received final approval from the Joint Committee on Taxation of the results of the IRS examination of its consolidated federal income tax returns for the 2005 through 2009 tax years; the 2007 through 2008 tax years of CityCenter Holdings, LLC; the 2008 through 2009 tax years of MGM Grand Detroit, LLC, a subsidiary treated as a partnership for income tax purposes; and the 2005 through 2009 tax years of Marina District Development Holding Company, LLC, an unconsolidated affiliate treated as a partnership for income tax purposes during such years. These examinations are now considered settled for financial reporting purposes. The Company previously deposited $30 million with the IRS to cover the expected cash taxes and interest resulting from the tentatively agreed adjustments for these examinations. As of December 31, 2016, other than adjustments resulting from the federal income tax audits discussed above, the Company was no longer subject to examination of its various state and local tax returns filed for years ended prior to 2012. During 2015, the state of New Jersey completed its examination of Marina District Development Holding Company, LLC for the 2003 through 2009 tax years. All adjustments were agreed to by the members of Marina District Development Holding Company, LLC and the examination is now considered settled for financial accounting purposes. The Company made a $1 million payment of tax and associated interest as a result of this settlement. No other state or local income tax returns are currently under examination. The Company does not anticipate that the total amounts of unrecognized tax benefits at December 31, 2016 will change materially within the next twelve months.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 13 – COMMITMENTS AND CONTINGENCIES Leases. The Company leases real estate and various equipment under operating and, to a lesser extent, capital lease arrangements. Certain real estate leases provide for escalation of rent based upon a specified price index and/or based upon periodic appraisals. At December 31, 2016, the Company was obligated under non-cancellable operating leases to make future minimum lease payments as follows: Years ending December 31, (In thousands) 2017 $ 37,173 2018 33,018 2019 29,722 2020 29,976 2021 32,416 Thereafter 1,380,274 Total minimum lease payments $ 1,542,579 The table above excludes the Company’s future lease obligations to a subsidiary of the Operating Partnership pursuant to the master lease agreement discussed in Note 19. The Company owns 76.3% of the Operating Partnership units as of December 31, 2016. The current obligations of $9 million under capital leases due within one year are included in “Other accrued liabilities” and the long-term obligations of $5 million under capital leases due after one year are included in “Other long-term obligations”. Rental expense for operating leases was $80 million, $74 million and $65 million for 2016, 2015 and 2014, respectively. Amounts included short term rentals charged to rent expense. Rental expense in 2016, 2015, and 2014 includes $7 million related to the Cotai land concession. The Company accounts for the Cotai land concession contract as an operating lease for which the required upfront payments are amortized over the initial 25-year contract term. Rent recognized for the Cotai land concession is included in “Preopening and start-up expenses” prior to opening. In August 2016, in connection with the Borgata transaction, the Company has assumed the liability of a series of ground leases for a total of approximately 11 acres of land on which the Borgata employee parking garage, public space expansion, rooms expansion, and modified surface parking lot. The Company recorded an unfavorable lease liability 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. The ground lease is accounted for as an operating lease with rental expense of $2 million for the year ended December 31, 2016. In April 2013, the Company entered into a ground lease agreement for an approximate 23 acre parcel of land in connection with the MGM National Harbor project. The ground lease has an initial term of 25 years and the right to extend for up to 13 additional six year periods with the first 7 of those additional periods considered to be reasonably assured. The Company therefore amortizes the lease on a straight line basis over a 67 year term. The ground lease is accounted for as an operating lease with rental expense of $16 million, $19 million and $13 million recorded Rent recognized for the ground lease was included in "Preopening and start-up expenses" prior to opening 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 will be reimbursed $72 million as settlement for property tax refunds subject to certain terms and conditions. The payment of the settlement amount is in satisfaction of existing 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 amounting to approximately $65 million. Under the terms of the agreement, Atlantic City will pay Borgata the reimbursement amount of $72 million in up to two installments, with the first installment of $52 million due on or before July 31, 2017 and the second installment for the remaining balance of $20 million due on or before October 1, 2017. In order to finance the reimbursement, Atlantic City and the State of New Jersey have agreed to use their best efforts to issue and sell bonds to pay the reimbursement. Should Atlantic City fail to pay either of the installment payments or petition for relief from creditors under state or federal law, or should any other event occur that would cause termination of the agreement, Borgata will be entitled to enforce a consent judgment that is being entered into as part of the settlement for the 2009-2015 tax years in an amount totaling $158 million. As part of the purchase and sale agreement, the Company agreed to pay Boyd Gaming half of any net amount received by the Company as it relates to the property tax refund owed to Borgata. The Company will recognize the amounts received pursuant to the reimbursement agreement and amounts paid to Boyd Gaming in current earnings in the periods in which payments are received and paid. NV Energy. In July 2016, the Company filed its notice to exit the fully bundled sales system of NV Energy and will purchase energy, capacity, and/or ancillary services from a provider other than NV Energy. The Company elected to pay the upfront impact payment of $83 million, including $14 million related to CityCenter. The upfront payments were made in September 2016. 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 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 non-bypassable charges liability has been recognized within “NV Energy exit expense” in the accompanying consolidated statements of operations. Subsequent accretion of the liability and changes in estimates will be recognized within general and administrative expenses. Grand Paradise Macau deferred cash payment. On September 1, 2016, the Company purchased 188.1 million common shares of its MGM China subsidiary from Grand Paradise Macau (“GPM”), an entity controlled by Ms. Ho, Pansy Catilina Chiu King (“Ms. Ho”). As part of the consideration for the purchase, the Company agreed to pay GPM a deferred cash payment of $50 million, which will be paid in amounts equal to the ordinary dividends received on such shares, with a final lump sum payment due on the fifth anniversary of the closing date of the transaction if any portion of the deferred cash payment remains unpaid at that time. As of December 31, 2016, the Company recorded a liability on a discounted basis of $43 million in “Other long-term obligations.” Cotai land concession contract. MGM Grand Paradise’s land concession contract for an approximate 18 acre site on the Cotai Strip in Macau became effective on January 9, 2013 and has an initial term of 25 years. The total land premium payable to the Macau government for the land concession contract is $161 million and is composed of a down payment and eight additional semi-annual payments. As of December 31, 2016, MGM China had paid $159 million of the contract’s premium, including interest due on the semi-annual installments, and the amount paid is recorded within “Other long-term assets, net.” In January 2017, MGM China paid the final semi-annual installment of $15 million under the contract . Under the terms of the land concession contract, MGM Grand Paradise is required to build and open MGM Cotai by January 2018. T-Mobile Arena. In conjunction with the Las Vegas Arena Company entering a senior secured credit facility in 2014, the Company and AEG each entered joint and several completion guarantees for the project, as well as a repayment guarantee for term loan B (which is subject to increases and decreases in the event of a rebalancing of the principal amount of indebtedness between the term loan A and term loan B facilities). As of December 31, 2016, term loan A was $150 million and term loan B was $50 million. The completion guarantees were terminated in February 2017. Other guarantees. The Company is 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 December 31, 2016, the Company had $15 million in letters of credit outstanding under the Company’s senior credit facility and $39 million in letters of credit outstanding under MGM China’s credit facility. No amounts were outstanding under the MGP senior credit facility and the MGM National Harbor credit facility at December 31, 2016. The amount of available borrowings under each of the credit facilities is 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.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Stock-Based Compensation	NOTE 15 — STOCK-BASED COMPENSATION MGM Resorts 2005 Omnibus Incentive Plan. The Company’s omnibus incentive plan, as amended (the “Omnibus Plan”), allows it to grant stock options, stock appreciation rights (“SARs”), restricted stock units (“RSUs”), performance share units (“PSUs”) and other stock-based awards to eligible directors, officers and employees of the Company and its subsidiaries. The Omnibus Plan is administered by the Compensation Committee (the “Committee”) of the Board of Directors. The Committee has discretion under the Omnibus Plan regarding which type of awards to grant, the vesting and service requirements, exercise price and other conditions, in all cases subject to certain limits, including: • As amended, the Omnibus Plan allows for the issuance of up to 45 million shares or share-based awards; and • For stock options and SARs, the exercise price of the award must be at least equal to the fair market value of the stock on the date of grant and the maximum term of such an award is 10 years. SARs granted under the Omnibus Plan generally have terms of seven years, and in most cases vest in four equal annual installments. RSUs granted vest ratably over four years, a portion of which are subject to achievement of a performance target based on operational results compared to budget in order for such RSUs to be eligible to vest. Expense is recognized primarily on a straight-line basis over the vesting period of the awards, net of estimated forfeitures. Estimated forfeitures are updated periodically with actual forfeitures recognized currently to the extent they differ from the estimate. PSUs granted vest subject to a market condition, in which a percentage of the target award granted vests based on the performance of the Company’s stock price in relation to the target price at the end of a three year performance period. Specifically, the ending average stock price must equal the target price, which is defined as 125% of the beginning average stock price, in order for the target award to vest. No shares are issued unless the ending average stock price is at least 60% of the target price, and the maximum payout is capped at 160% of the target award. If the ending average stock price is at least 60% or more of the target price, then the amount of units granted in the target award is multiplied by the stock performance multiplier. The stock performance multiplier equals the ending average stock price divided by the target price. For this purpose, the target and ending prices are based on the average closing price of the Company’s common stock over the 60 calendar day periods ending on the grant date and the third anniversary of the grant date, respectively. Expense is recognized on a graded basis over the performance period beginning on the date of grant. Estimated forfeitures are updated periodically with actual forfeitures recognized currently to the extent they differ from the estimate. As of December 31, 2016, the Company had an aggregate of approximately 21 million shares of common stock available for grant as share-based awards under the Omnibus Plan.

As of December 31, 2016, there was a total of $28 million of unamortized compensation related to PSUs which is expected to be recognized over a weighted-average period of 1.7 years. The Company grants PSUs for a portion of any calculated bonus for a Section 16 officer of the Company that is in excess of such officer’s base salary (the “Bonus PSU Policy”). Awards granted under the Bonus PSU Policy have the same terms as the other PSUs granted under the Omnibus Plan with the exception that as of the grant date the awards will not be subject to forfeiture in the event of the officer’s termination.

The Company’s subsidiary, MGP, adopted an omnibus incentive plan in 2016 for grants of share-based awards to eligible directors, officers and employees of MGP and its subsidiaries and affiliates, including the Company (“MGP Omnibus Plan”). The MGP Omnibus Plan is administered by MGP’s Board of Directors, which has the discretion to determine the type of awards to grant, the vesting and service requirements, exercise price and other conditions, in all cases subject to certain limits, including: • The MGP Omnibus Plan allows for the issuance of up to 2.5 million shares; and • Limits the maximum amount of shares to be granted, in the aggregate, to any individual participant within any fiscal year as well as limits the maximum aggregate grant date value (regardless of type(s) of award granted) in any fiscal year to any non-employee director of MGP. The majority of RSUs granted under the MGP Omnibus Plan vest ratably over four years with the exception of RSUs issued to MGM Resorts International employees in connection with the IPO, which vest ratably over one year. Expense is recognized on a straight-line basis over the vesting period of the awards, net of estimated forfeitures. Estimated forfeitures are updated periodically with actual forfeitures recognized currently to the extent they differ from the estimate. The RSUs are granted together with dividend equivalent rights that are subject to the same vesting and forfeiture terms as the underlying RSUs. Outstanding PSUs granted under the MGP Omnibus Plan vest subject to a market condition, in which a percentage of the target award granted vests based on MGP’s total shareholder return (“TSR”) relative to a select group of peer companies at the end of a three year performance period. Depending on MGP’s relative TSR at the end of the performance period, anywhere from 0% to 160% of the target award may vest. Should MGP’s TSR be negative during the performance period, then the maximum portion of the target award eligible for vesting is capped at 100%. Expense is recognized on a graded basis over the performance period beginning on the date of grant. Estimated forfeitures are updated periodically with actual forfeitures recognized currently to the extent they differ from the estimate. The PSUs are granted together with dividend equivalent rights that are subject to the same vesting and forfeiture terms as the underlying PSUs.

Compensation And Retirement Disclosure [Abstract]
Employee Benefit Plans	NOTE 16 — EMPLOYEE BENEFIT PLANS Multi-employer benefit plans. Employees of the Company who are members of various unions are covered by union-sponsored, collectively bargained, multiemployer health and welfare and defined benefit pension plans. Of these plans, the Company considers the Southern Nevada Culinary and Bartenders Pension Plan (the “Pension Plan”), under the terms of collective bargaining agreements with the Local Joint Executive Board of Las Vegas for and on behalf of Culinary Workers Union Local No. 226 and Bartenders Union Local No. 165, to be individually significant. The risk of participating in the Pension Plan differs from single-employer plans in the following aspects: a) Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers; b) If a participating employer stops contributing to the plan, the unfunded obligations of the plan may be borne by the remaining participating employers; c) If an entity chooses to stop participating in some of its multiemployer plans, the entity may be required to pay those plans an amount based on the underfunded status of the plan, referred to as a withdrawal liability; and d) If the Pension Plan is terminated by withdrawal of all employers and if the value of the nonforfeitable benefits exceeds plan assets and withdrawal liability payments, employers are required by law to make up the insufficient difference. Pursuant to its collective bargaining agreements referenced above, the Company also contributes to UNITE HERE Health (the “Health Fund”), which provides healthcare benefits to its active and retired members. The Company’s participation in the Pension Plan is outlined in the table below. Expiration Date Pension Protection Act of Collective EIN/Pension Zone Status (1) Bargaining Pension Fund Plan Number 2015 2014 Agreements (2) Southern Nevada Culinary and Bartenders Pension Plan 88-6016617/001 Green Green 5/31/2018 (1) In 2014, the trustees of the Pension Plan elected to apply the extended amortization and the special ten-year asset smoothing rules under the Pension Relief Act of 2010. (2) The Company is party to ten collective bargaining agreements that require contributions to the Pension Plan. The agreements between CityCenter Hotel Casino, LLC, Bellagio, Mandalay Corp., MGM Grand Hotel, LLC and the Local Joint Executive Board of Las Vegas are the most significant because more than half of the Company’s employee participants in the Pension Plan are covered by those four agreements. Contributions to the Company’s multi-employer pension plans and other multi-employer benefit plans were as follows: Year Ended December 31, 2016 2015 2014 Multi-employer Pension Plans (In thousands) Southern Nevada Culinary and Bartenders Pension Plan $ 44,001 $ 41,904 $ 33,927 Other pension plans not individually significant 8,592 9,680 7,323 Total multi-employer pension plans $ 52,593 $ 51,584 $ 41,250 Multi-employer Benefit Plans Other Than Pensions UNITE HERE Health $ 187,356 $ 191,733 $ 202,641 Other 11,513 12,840 12,746 Total multi-employer benefit plans other than pensions $ 198,869 $ 204,573 $ 215,387 Pension Plan contributions in 2016 increased when compared to 2015 due to the contribution rate to the Pension Plan increasing in mid-2016 as defined under the collective bargaining agreements, which was partially offset by a 3% decrease in hours worked in 2016 compared to 2015. During 2014 an amendment to the collective bargaining agreements to temporarily divert contributions from the Pension Plan to the Health Fund was in effect. As a result, contributions to the Pension Plan increased in 2015 compared to 2014 as the amendment ended in June of 2014. Borgata. The above disclosures exclude multi-employer defined benefit pension plans under terms of collective-bargaining agreements that cover union-represented employees at Borgata (acquired on August 1, 2016). These unions cover certain of its culinary, hotel and other trade workers. Borgata is obligated to make defined contributions under these plans and is also subject to the risks outlined above for the Company’s other multi-employer pension plans. Contributions, based on wages paid to covered employees, totaled $4 million, for the period from acquisition through December 31, 2016. Borgata’s most significant plan is the Legacy Plan of the National Retirement Fund, Former HEREIU and Local 54 (the “The Local 54 Pension Plan”), which has been listed in “critical status” (which means it is generally less than 65% funded) and a rehabilitation plan has been adopted. As a result, the Company is responsible for the payment of surcharges in addition to the contribution rate specified in the collective bargaining agreement. The Company estimates Borgata’s share of unfunded vested liabilities related to certain multi-employer pension plans is approximately $288 million as of January 1, 2016, which amount primarily relates to The Local 54 Pension Plan, and which amount is subject to change each year depending on the applicable plan ’ s employer contributions, investment performance and other factors. Borgata has no current intention to withdraw from these plans, which withdrawal could result in the incurrence of a contingent liability that would be payable in an amount and at such time (or over a period of time) that would vary based on a number of factors at the time of (and after) withdrawal. Self-insurance. The Company is self-insured for most health care benefits and workers compensation for its non-union employees. The liability for health care claims filed and estimates of claims incurred but not reported was $30 million and $22 million at December 31, 2016 and 2015, respectively. The workers compensation liability for claims filed and estimates of claims incurred but not reported was $53 million and $43 million as of December 31, 2016 and 2015, respectively. Both liabilities are included in “Other accrued liabilities.” Retirement savings plans. The Company has retirement savings plans under Section 401(k) of the IRC for eligible employees. The plans allow employees to defer, within prescribed limits, up to 75% of their income on a pre-tax and/or after-tax basis through contributions to the plans. The Company matches 50% of the first 6% of eligible employee deferrals up to a specified annual maximum dollar amount. The Company recorded charges for 401(k) contributions of $20 million, $16 million and $17 million in 2016, 2015 and 2014, respectively. The Company maintains nonqualified deferred retirement plans for certain key employees. The plans allow participants to defer, on a pre-tax basis, a portion of their salary and bonus and accumulate tax deferred earnings, plus investment earnings on the deferred balances, as a deferred tax savings. All employee deferrals vest immediately. The Company does not contribute to the plan. The Company also maintains nonqualified supplemental executive retirement plans (“SERP”) for certain key employees. Until September 2008, the Company made quarterly contributions intended to provide a retirement benefit that is a fixed percentage of a participant’s estimated final five-year average annual salary, up to a maximum of 65%. The Company has indefinitely suspended these contributions. Employees do not make contributions under these plans. A portion of the Company contributions and investment earnings thereon vest after three years of SERP participation and the remaining portion vests after both five years of SERP participation and 10 years of continuous service. MGM China. MGM China contributes to a retirement plan as part of an employee benefits package for eligible employees. The Company recorded charges related to contributions in the retirement plan of $7 million, $7 million and $5 million for the years ended December 31, 2016, 2015, and 2014, respectively.

Segment Reporting [Abstract]
Segment Information	NOTE 18 — 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 Omnibus Plan and the MGP 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.

MGP 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 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. 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 transaction. 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 generally accepted accounting principles, 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 year ended December 31, 2016, the Company made rent payments to the Landlord in the amount of $418 million. 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. The Company was in compliance with all applicable covenants as of December 31, 2016. 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. 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]
Consolidating Condensed Financial Information	NOTE 20 — CONSOLIDATING CONDENSED FINANCIAL INFORMATION As of December 31, 2016, 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 and 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 statement information for the subsidiary guarantors and non-guarantors as of December 31, 2016 and 2015 and for the years ended December 31, 2016, 2015 and 2014, are presented below. Within the Condensed Consolidating Statements of Cash Flows for the periods ending December 31, 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 December 31, 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.

Accounting Policies [Abstract]
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 MGP’s 26.7% interest in the Operating Partnership prior to the Borgata transaction and 23.7% interest subsequent to the Borgata transaction as noncontrolling interest in the Company’s consolidated financial statements. As of December 31, 2016, on a consolidated basis 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.
Management's use of estimates	Management’s use of estimates. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America. These principles require the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair value measurements	Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, i nvestments 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 10; • Level 2 inputs when measuring the fair value of its interest rate swaps. See Note 11; • Level 2 and Level 3 inputs when assessing the fair value of assets acquired and liabilities assumed during the Borgata transaction. See Note 4; • Level 2 and Level 3 inputs when measuring the impairment of goodwill related to the MGM China reporting unit. See Note 8; and • Level 3 inputs when assessing the fair value of its investment in Grand Victoria. See Note 7
Cash and cash equivalents	Cash and cash equivalents. Cash and cash equivalents include investments and interest bearing instruments with maturities of 90 days or less at the date of acquisition. Such investments are carried at cost, which approximates market value. Book overdraft balances resulting from the Company’s cash management program are recorded as accounts payable or construction payable as applicable.
Accounts receivable and credit risk	Accounts receivable and credit risk. Financial instruments that potentially subject the Company to concentrations of credit risk consist primaril y of casino accounts receivable. The Company issues credit to approved casino customers and gaming promoters following background checks and investigations of creditworthiness. At December 31, 2016, 47% of the Company’s casino receivables at its domestic resorts were due from customers residing in foreign countries and 9% of the Company’s casino receivables related to MGM China. Business or economic conditions or other significant events in these countries could affect the collectability of such receivables. Accounts receivable are typically non-interest bearing and are initially recorded at cost. Accounts are written off when management deems the account to be uncollectible. Recoveries of accounts previously written off are recorded when received. An estimated allowance for doubtful accounts is maintained to reduce the Company’s receivables to their net carrying amount, which approximates fair value. The allowance is estimated based on both a specific review of customer accounts as well as historical collection experience and current economic and business conditions. Management believes that as of December 31, 2016, no significant concentrations of credit risk existed for which an allowance had not already been recorded.
Inventories	Inventories. Inventories c onsist primarily of food and beverage, retail merchandise and operating supplies, and are stated at the lower of cost or net realizable value. Cost is determined primarily using the average cost method for food and beverage and operating supplies. Cost for retail merchandise is determined using the cost method.
Property and equipment	Property and equipment. Property and equipment are stated at cost. A significant amount of the Company’s property and equipment was acquired through business combinations and therefore recognized at fair value at the acquisition date. Gains or losses on dispositions of property and equipment are included in the determination of income or loss. Maintenance costs are expensed as incurred. As of December 31, 2016 and 2015, the Company had accrued $36 million and $17 million for property and equipment within accounts payable and $32 million and $44 million related to construction retention accrued in other long-term liabilities, respectively. Property and equipment are generally depreciated over the following estimated useful lives on a straight-line basis: Buildings and improvements 20 to 40 years Land improvements 10 to 20 years Furniture and fixtures 3 to 20 years Equipment 3 to 15 years The Company evaluates its property and equipment and other long-lived assets for impairment based on its classification as held for sale or to be held and used. Several criteria must be met before an asset is classified as held for sale, including that management with the appropriate authority commits to a plan to sell the asset at a reasonable price in relation to its fair value and is actively seeking a buyer. For assets held for sale, the Company recognizes the asset at the lower of carrying value or fair market value less costs to sell, as estimated based on comparable asset sales, offers received, or a discounted cash flow model. For assets to be held and used, the Company reviews for impairment whenever indicators of impairment exist. The Company then compares the estimated future cash flows of the asset, on an undiscounted basis, to the carrying value of the asset. If the undiscounted cash flows exceed the carrying value, no impairment is indicated. If the undiscounted cash flows do not exceed the carrying value, then an impairment charge is recorded based on the fair value of the asset, typically measured using a discounted cash flow model. If an asset is still under development, future cash flows include remaining construction costs. All recognized impairment losses, whether for assets held for sale or assets to be held and used, are recorded as operating expenses.
Capitalized interest	Capitalized interest. The interest cost associated with major development and construction projects is capitalized and included in the cost of the project. When n o debt is incurred specifically for a project, interest is capitalized on amounts expended on the project using the weighted-average cost of the Company’s outstanding borrowings. Capitalization of interest ceases when the project is substantially complete or development activity is suspended for more than a brief period.
Investments in and advances to unconsolidated affiliates	Investments in and advances to unconsolidated affiliates. The Company has investments in unconsolidated affiliates accounted for under the equity method. Under the equity method, carryi ng value is adjusted for the Company’s share of the investees’ earnings and losses, amortization of certain basis differences, as well as capital contributions to and distributions from these companies. Distributions in excess of equity method earnings are recognized as a return of investment and recorded as investing cash inflows in the accompanying consolidated statements of cash flows. The Company classifies operating income and losses as well as gains and impairments related to its investments in unconsolidated affiliates as a component of operating income or loss, as the Company’s investments in such unconsolidated affiliates are an extension of the Company’s core business operations. The Company evaluates its investments in unconsolidated affiliates for impairment whenever events or changes in circumstances indicate that the carrying value of its investment may have experienced an “other-than-temporary” decline in value. If such conditions exist, the Company compares the estimated fair value of the investment to its carrying value to determine if an impairment is indicated and determines whether the impairment is “other-than-temporary” based on its assessment of all relevant factors, including consideration of the Company’s intent and ability to retain its investment. The Company estimates fair value using a discounted cash flow analysis based on estimated future results of the investee and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. See Note 7 and Note 17 for results of the Company’s review of its investment in certain of its unconsolidated affiliates.
Goodwill and other intangible assets	Goodwill and other intangible assets. Goodwill represents the excess of purchase price over fair market value of net assets acquired in business combinations. Goodwill and indefinite-lived intangible assets must be reviewed for impairment at least annually and between annual test dates in certain circumstances. The Company performs its annual impairment tests in the fourth quarter of each fiscal year. No impairments were indicated or recorded as a result of the annual impairment review for goodwill and indefinite-lived intangible assets in 2016 and 2014. An impairment of goodwill related to the MGM China reporting unit was recorded as a result of the annual impairment review in 2015. See Note 8. Accounting guidance provides entities the option to perform a qualitative assessment of goodwill (commonly referred to as “step zero”) in order to determine whether further impairment testing is necessary. In performing the step zero analysis the Company considers macroeconomic conditions, industry and market considerations, current and forecasted financial performance, entity-specific events, and changes in the composition or carrying amount of net assets of reporting units. In addition, the Company takes into consideration the amount of excess of fair value over carrying value determined in the last quantitative analysis that was performed, as well as the period of time that has passed since the last quantitative analysis. If the step zero analysis indicates that it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the entity would proceed to a two-step quantitative analysis. Under the two-step quantitative analysis, goodwill for relevant reporting units is tested for impairment using a discounted cash flow analysis based on the estimated future results of the Company’s reporting units discounted using market discount rates and market indicators of terminal year capitalization rates, and a market approach that utilizes business enterprise value multiples based on a range of multiples from the Company’s peer group. If the carrying value of the reporting unit exceeds its fair value, an indication of impairment exists and the Company must proceed to measure an impairment loss, if any. To measure an impairment loss, the implied fair value of a reporting unit’s goodwill is compared to the carrying value of that goodwill. The implied fair value of goodwill is determined by allocating the fair value of the reporting unit to its assets and liabilities and the amount remaining, if any, is the implied fair value of goodwill. If the implied fair value of goodwill is less than its carrying value then it must be written down to its implied fair value. License rights are tested for impairment using a discounted cash flow approach, and trademarks are tested for impairment using the relief-from-royalty method. If the fair value of an indefinite-lived intangible asset is less than its carrying amount, an impairment loss is recognized equal to the difference.
Revenue recognition and promotional allowances	Revenue recognition and promotional allowances. Casino revenue is the aggregate net difference between gaming wins and losses, with liabili ties recognized for funds deposited by customers before gaming play occurs (“casino front money”) and for chips in the customers’ possession (“outstanding chip liability”). Hotel, food and beverage, entertainment, retail and other operating revenues are recognized as services are performed and goods are provided. Advance deposits on rooms and advance ticket sales are recorded as accrued liabilities until services are provided to the customer. Gaming revenues are recognized net of certain sales incentives, including discounts and points earned in point-loyalty programs. The retail value of hotel rooms, food and beverage, and other services furnished to guests without charge is included in gross revenue and then deducted as promotional allowances. The estimated cost of providing promotional allowances is primarily included in casino expenses as follows: Year Ended December 31, 2016 2015 2014 (In thousands) Rooms $ 120,369 $ 112,313 $ 115,463 Food and beverage 283,598 279,041 295,667 Entertainment, retail and other 39,611 39,388 39,673 $ 443,578 $ 430,742 $ 450,803
Gaming promoters	Gaming promoters. A significant portion of the high-end (“VIP”) gaming volume at MGM Macau is generated through the use of gaming promoters, also known as junket operators. These operators introduce VIP gaming players to MGM Macau, assist these customers with travel arrangements, and extend gaming credit to these players. VIP gaming at MGM Macau is conducted by the use of special purpose nonnegotiable gaming chips. Gaming promoters purchase these nonnegotiable chips from MGM Macau and in turn sell these chips to their players. The nonnegotiable chips allow MGM Macau to track the amount of wagering conducted by each gaming promoter’s clients in order to determine VIP gaming play volume, or rolling chip turnover, which is the amount of nonnegotiable chips wagered and lost. In exchange for the gaming promoters’ services, MGM Macau compensates the gaming promoters through revenue-sharing arrangements and rolling chip turnover-based commissions. The estimated portion of the gaming promoter commissions that represent amounts passed through to VIP customers is recorded as a reduction of casino revenue, and the estimated portion retained by the gaming promoter for its compensation is recorded as casino expense.
Reimbursed costs	Reimbursed costs. The Company recognizes costs reimbursed pursuant to management services as revenue in the period it incurs the costs. Reimbursed costs related primarily to the Company’s management of CityCenter.
Loyalty programs	Loyalty programs. The Company’s primary loyalty progra m is “M life Rewards” and is available to patrons at most of the Company’s domestic resorts and CityCenter. Members may earn points and/or Express Comps for their gaming play which can be redeemed at restaurants, box offices or the M life Rewards front desk at participating properties. Points may also be redeemed for free slot play on participating machines. The Company records a liability based on the points earned multiplied by the redemption value, less an estimate for points not expected to be redeemed, and records a corresponding reduction in casino revenue. Customers also earn Express Comps based on their gaming play which can be redeemed for complimentary goods and services, including hotel rooms, food and beverage, and entertainment. The Company records a liability for the estimated costs of providing goods and services for Express Comps based on the Express Comps earned multiplied by a cost margin, less an estimate for Express Comps not expected to be redeemed and records a corresponding expense in the casino department. MGM Macau also has a loyalty program, whereby patrons earn rewards that can be redeemed for complimentary services, including hotel rooms, food and beverage, and entertainment.
Advertising	Advertising. The Company expenses advertising costs the first time the advertising takes place. Advertising expense, which is generally included in general and administrative expenses, was $171 million for 2016 and $156 million for 2015 and 2014.
Corporate expense	Corporate expense. Corporate expense represents unall ocated payroll, aircraft costs, professional fees and various other expenses not directly related to the Company’s casino resort operations. In addition, corporate expense includes the costs associated with the Company’s evaluation and pursuit of new business opportunities, which are expensed as incurred.
Preopening and start-up expenses	Preopening and start-up expenses. Preopening and start-up costs, including organizational costs, are expensed as incurred. Costs classified as preopening and start-up expenses include payroll, outside services, advertising, and other expenses related to new or start-up operations.
Property transactions, net	Property transactions, net. The Company classifies transactions such as write-downs and impairments, demolition costs, and normal gains and losses on the sale of assets as “Property transactions, net.” See Note 17 for a detailed discussion of these amounts.
Redeemable noncontrolling interest	Redeemable noncontrolling interest. In 2015, MGM National Harbor issued non-voting economic interests in MGM National Harbor (“Interests”) to noncontrolling interest parties, for a total purchase price of $6 million. In 2016, MGM National Harbor issued Interests to noncontrolling interest parties for a purchase price of $47 million. Net income attributable to noncontrolling interests includes $0.5 million relating to redeemable noncontrolling interests for the year ended December 31, 2016. The Interests provide for annual preferred distributions by MGM National Harbor to the noncontrolling interest parties based on a percentage of its annual net gaming revenue (as defined in the MGM National Harbor operating agreement). Such distributions will begin within ninety days after the end of the fiscal year in which the opening date of MGM National Harbor occurs, and after the end of each subsequent fiscal year. Also, beginning on the third anniversary of the last day of the calendar quarter in which the opening date of MGM National Harbor occurs (and on each subsequent anniversary thereof) the noncontrolling interest parties will each have the ability to require MGM National Harbor to purchase all or a portion of their Interests for a purchase price based on a contractually agreed upon formula. Certain noncontrolling interest parties each have the right to sell back all or a portion of their Interests prior to such date if MGM National Harbor were to guarantee or grant liens to secure any indebtedness of the Company or its affiliates other than the indebtedness of MGM National Harbor. The Company has recorded the Interests as “Redeemable noncontrolling interests” in the mezzanine section of the accompanying consolidated balance sheets and not stockholders’ equity because their redemption is not exclusively in the Company’s control. Interests are initially accounted for at fair value. Subsequently, the Company will recognize changes in the redemption value as they occur and adjust the carrying amount of the redeemable noncontrolling interests to equal the maximum redemption value, provided such amount does not fall below the initial carrying value, at the end of each reporting period. The Company records any changes caused by such an adjustment in retained earnings or accumulated deficit. Additionally the carrying amount of the redeemable noncontrolling interests is adjusted for annual preferred distributions, with changes caused by such adjustments recorded within net income (loss) attributable to noncontrolling interests.
Income (loss) per share of common stock	Income (loss) per share of common stock. The table below reconciles basic and diluted income (loss) per share of common stock. Diluted net income (loss) attributable to common stockholders includes adjustments for redeemable noncon trolling interests and the potentially dilutive effect on the Company’s equity interests in MGP and MGM China due to shares outstanding under their respective stock compensation plans. Diluted weighted-average common and common equivalent shares includes adjustments for potential dilution of share-based awards outstanding under the Company’s stock compensation plan.

The weighted-average impact of the assumed conversion of the convertible senior notes was excluded from the calculation of diluted earnings per share for the years ended December 31, 2015 and 2014 as their effect would be antidilutive. See Note 10 for additional information.
Currency translation	Currency translation. The Company translates the financial statements of foreign subsidiaries that are not denominated in U.S. do llars. Balance sheet accounts are translated at the exchange rate in effect at each balance sheet date. Income statement accounts are translated at the average rate of exchange prevailing during the period. Translation adjustments resulting from this process are recorded to other comprehensive income (loss).
Derivative financial instruments	Derivative financial instruments. The Company reflects all derivative instruments at fair value as either assets or liabilities. For derivative instruments that are designated and qualify as hedging instruments, the effective portion of the gain or loss on the cash flow hedge instruments is recorded as a component of accumulated other comprehensive income. Any ineffective portion of a derivative’s change in fair value is immediately recognized within net income. As of December 31, 2016, all of the Company’s derivative financial instruments are interest rate swap agreements which have been designated as cash flow hedges and qualify for hedge accounting.
Accumulated other comprehensive income (loss)	Accumulated other comprehensive income (loss). Comprehensive income (loss) includes net income (loss) and all other non-stockholder changes in equity, or other comprehensive income (loss). Elements of the Company’s accumulated other comprehensive income are reported in the accompanying consolidated statements of stockholders’ equity. The following table summarizes the changes in the accumulated balance of other comprehensive income: Currency translation adjustments Cash Flow Hedges Other Total (In thousands) Balance, December 31, 2014 $ 12,319 $ — $ 672 $ 12,991 Other comprehensive income (loss) before reclassifications 3,727 — (672 ) 3,055 Amounts reclassified from accumulated other comprehensive income — — — — Other comprehensive income (loss), net of tax 3,727 — (672 ) 3,055 Other comprehensive income (loss) attributable to noncontrolling interest (2,024 ) — — (2,024 ) Balance, December 31, 2015 14,022 — — 14,022 Other comprehensive income (loss) before reclassifications (2,680 ) 1,521 1,074 (85 ) Amounts reclassified from accumulated other comprehensive income — 358 — 358 Other comprehensive income (loss), net of tax (2,680 ) 1,879 1,074 273 Other comprehensive income (loss) attributable to noncontrolling interest 1,203 (445 ) — 758 Balance, December 31, 2016 $ 12,545 $ 1,434 $ 1,074 $ 15,053
Recently issued accounting standards	Recently issued accounting standards. In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-15, “Presentation of Financial Statements - Going Concern (Subtopic 205-40).” The guidance is intended to define management’s responsibility to evaluate whether there is substantial doubt about an organization’s ability to continue as a going concern and to provide related footnote disclosures. This ASU provides guidance to an organization’s management, with principles and definitions that are intended to reduce diversity in the timing and content of disclosures that are commonly provided by organizations today in the financial statement footnotes. The Company adopted this guidance prospectively at the beginning of the fourth quarter of 2016. The adoption of this guidance did not have an effect on the Company’s financial condition, results of operations, cash flows, or disclosures. 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),” 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),” 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,” 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,” 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 as discussed above. 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 as outlined above 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, 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 will need to assess 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 that 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 will 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 will not have a material effect on the Company’s consolidated financial statements and footnote disclosures. In January 2017, the FASB issued ASU No. 2017-04, “Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” The amended guidance simplifies the subsequent measurement of goodwill by eliminating step two from the goodwill impairment test. Under the amended guidance, the Company will perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying value, and an impairment charge will be recognized for the amount by which the carrying value exceeds the reporting unit’s fair value, not to exceed the total amount of goodwill allocated to that reporting unit. This guidance is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2021, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company is currently evaluating the impact and timing of adopting this guidance, but anticipates early adoption in 2017.

Complementary tax exemption expiration date	Dec. 31, 2016
Tax credit carryforward, description	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. 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 will thus not be able to credit the Macau Special Gaming Tax in such years, and has factored that assumption into the assessment of the realization of the foreign tax credit deferred tax asset.

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 generally accepted accounting principles, 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%).
