Organization Consolidation And Presentation Of Financial Statements [Abstract]
Organization	NOTE 1 — ORGANIZATION Organization. MGM Resorts International (the “Company”) is a Delaware corporation that acts largely as a holding company and, through wholly owned subsidiaries, owns and/or operates casino resorts. The Company owns and operates the following casino resorts in Las Vegas, Nevada: Bellagio, MGM Grand Las Vegas, The Mirage, Mandalay Bay, Luxor, New York-New York, Monte Carlo, Excalibur and Circus Circus Las Vegas. Operations at MGM Grand Las Vegas include management of The Signature at MGM Grand Las Vegas, a condominium-hotel consisting of three towers. In July 2015, the Company entered into an agreement to sell Circus Circus Reno in Reno, Nevada, as discussed in Note 3. Along with local investors, the Company owns and operates MGM Grand Detroit in Detroit, Michigan. The Company owns and operates two resorts in Mississippi: Beau Rivage in Biloxi and Gold Strike in Tunica. The Company also owns Shadow Creek, an exclusive world-class golf course located approximately ten miles north of its Las Vegas Strip resorts, Primm Valley Golf Club at the California/Nevada state line and Fallen Oak golf course in Saucier, Mississippi. The Company owns 51% and has a controlling interest in MGM China Holdings Limited (“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 concession. MGM Grand Paradise also has a land concession contract with the government of Macau to develop a second resort and casino on an approximately 18 acre site in Cotai, Macau (“MGM Cotai”). MGM Cotai will be an integrated casino, hotel and entertainment complex with capacity for up to 500 gaming tables and up to 1,500 slots, and featuring approximately 1,500 hotel rooms. The total estimated project budget is $3.0 billion, excluding development fees eliminated in consolidation, capitalized interest and land related costs. The Company owns 50% of 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, a casino resort; Mandarin Oriental Las Vegas, a non-gaming boutique hotel; Crystals, a retail, dining and entertainment district; and Vdara, a luxury condominium-hotel. In addition, CityCenter features residential units in the Residences at Mandarin Oriental and Veer. The Company receives a management fee of 2% of revenues for the management of Aria and Vdara, and 5% of EBITDA (as defined in the agreements governing the Company’s management of Aria and Vdara). In addition, the Company receives an annual fee of $3 million for the management of Crystals. See Note 4 for additional information related to CityCenter. The Company owns 50% of the Borgata Hotel Casino & Spa (“Borgata”) located on Renaissance Pointe in the Marina area of Atlantic City, New Jersey. Boyd Gaming Corporation owns the other 50% of Borgata and also operates the resort. 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. In July 2015, the Company entered an agreement to sell its 50% interest in Silver Legacy, located in Reno, Nevada. See Note 4 for additional information regarding the Company’s investments in unconsolidated affiliates. The Company has entered into management agreements for future non-gaming hotels, resorts and residential products in the Middle East, North Africa, India and the United States. In 2014, the Company and the Hakkasan Group formed MGM Hakkasan Hospitality (“MGM Hakkasan”), owned 50% by each member, to design, develop and manage luxury non-gaming hotels, resorts and residences under certain brands licensed from the Company and the Hakkasan Group. Upon formation, the Company contributed its management agreements for non-gaming hotels, resorts and residential projects (outside of the greater China region) under development to MGM Hakkasan. In May 2015, the Company and the Hakkasan Group mutually agreed to terminate MGM Hakkasan and the brand license from Hakkasan Group. The Company will continue to develop these projects under its brands through MGM Hospitality (a wholly-owned subsidiary). Additionally, the Company will continue to develop and manage properties in the greater China region with Diaoyutai State Guesthouse, including MGM Grand Sanya. The Maryland Video Lottery Facility Location Commission has awarded the Company’s subsidiary developing MGM National Harbor the license to build and operate a destination casino resort in Prince George’s County at National Harbor, which is a waterfront development located on the Potomac River just outside of Washington D.C. The expected cost to develop and construct MGM National Harbor is approximately $1.3 billion, excluding capitalized interest and land related costs. The Company expects the resort to include a casino with approximately 3,600 slots and 160 table games including poker; a 300-room hotel with luxury spa and rooftop pool; 93,100 square feet of high‑end branded retail and fine and casual dining; a 3,000-seat theater venue; 50,000 square feet of meeting and event space; and a 4,700-space parking garage. A subsidiary of the Company was awarded the Category One casino license in Region B, Western Massachusetts, one of three licensing regions designated by legislation, to build and operate MGM Springfield. MGM Springfield will be developed on approximately 14 acres of land in downtown Springfield, Massachusetts. The Company’s plans for the resort originally included a casino with approximately 3,000 slots and 100 table games including poker; a 250-room hotel tower; 90,000 square feet of retail and restaurant space; 45,000 square feet of meeting and event space; and a 3,500-space parking garage, with an expected development and construction cost of approximately $760 million, excluding capitalized interest and land related costs. The Company has recently undertaken a design and cost review of MGM Springfield and has proposed design and scope changes for various elements of the project. The proposed changes have been submitted to Springfield’s Mayor and City Council and the Massachusetts Gaming Commission for approval. The Company’s review of construction costs remains underway and will be impacted by the final determination of project design and scope, but the Company currently anticipates the cost may increase from the previous estimate of approximately $760 million. In 2013, the Company formed Las Vegas Arena Company, LLC (the “Las Vegas Arena Company”) with a subsidiary of Anschutz Entertainment Group, Inc. (“AEG”) – a leader in sports, entertainment, and promotions – to design, construct, and operate the Las Vegas Arena, which will be 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 Company and AEG each owns 50% of Las Vegas Arena Company. The Las Vegas Arena is anticipated to seat between 18,000 and 20,000 people. Such development is estimated to cost approximately $350 million, excluding capitalized interest and land related costs. The Company has two reportable segments: wholly owned domestic resorts and MGM China. See Note 11 for additional information about the Company’s segments.

Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	NOTE 2 — BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2014 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year. 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 uses Level 1 inputs for its long-term debt fair value disclosures. See Note 5. Property and equipment. As of September 30, 2015, the Company had accrued $11 million for property and equipment within “Accounts payable” and $38 million related to construction retention in “Other long-term obligations.” In addition, during the nine months ended September 30, 2015, the Company entered into capital leases with obligations of $12 million. 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. Due to a significant decrease in MGM China’s cash flows as well as a decline in the market capitalization of MGM China relative to its net book value, the Company performed an interim impairment test of goodwill related to the MGM China reporting unit in the second quarter of 2015. 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 reporting unit’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. In measuring 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. The results of the Company’s interim impairment test indicated the fair value of the MGM China reporting unit exceeded its carrying value by 9%. Therefore, the Company concluded that the carrying value of goodwill of $2.8 billion related to MGM China was not impaired based on the interim test. The Company has continued monitoring the results of this reporting unit and determined that circumstances did not exist that would require the Company to perform an interim impairment test in the third quarter of 2015. Redeemable noncontrolling interest . In April 2015, MGM National Harbor issued non-voting membership interests in MGM National Harbor (“Membership Interests”) to Radio One, Inc. (“Radio One”), a noncontrolling interest party, for a purchase price of $5 million. In addition, Radio One was given the right to make one additional capital contribution of up to $35 million prior to July 1, 2016 for the purchase of additional Membership Interests. The Membership Interests provide for annual preferred distributions by MGM National Harbor to Radio One 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) Radio One will have the ability to require MGM National Harbor to purchase all or a portion of its Membership Interests for a purchase price that is based on a contractually agreed upon formula. Radio One also has the right to sell back all or a portion of its Membership Interest prior to such date if MGM National Harbor were to guarantee or grant liens to secure any indebtedness of the Company other than the indebtedness of MGM National Harbor. The Company has recorded the Membership Interests as “Redeemable noncontrolling interest” 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. Membership 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 will reflect any changes caused by such an adjustment in retained earnings. Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate was (21.1)% and (21.4)% for the three and nine months ended September 30, 2015, respectively. The Company recognizes deferred tax assets, net of applicable reserves, related to tax loss and credit carryforwards and other temporary differences with a future tax benefit to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. As of December 31, 2014, the scheduled future reversal of existing U.S. federal taxable temporary differences exceeded the scheduled future reversal of existing U.S. federal deductible temporary differences. Consequently, the Company no longer applies a valuation allowance against its domestic deferred tax assets other than its foreign tax credit deferred tax asset. The Company generates significant excess foreign tax credits each year that are attributable to the Macau Special Gaming Tax which is 35% of gross gaming revenue in Macau. Because MGM China is presently exempt from the Macau 12% complementary tax on gaming profits, the Company believes that payment of the Macau Special Gaming Tax qualifies as a tax paid in lieu of an income tax that is creditable against U.S. taxes. As long as the exemption from Macau’s 12% complementary tax on gaming profits continues and the Company continues to receive distributions from MGM China, the Company expects that it will generate excess foreign tax credits on an annual basis and that none of the excess foreign credits will be utilized until the exemption expires. Although the Company’s current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, the Company believes it will be entitled to receive a third five-year exemption from Macau based upon exemptions granted to the Company’s competitors in order to ensure non-discriminatory treatment among gaming concessionaires and subconcessionaires. For all periods beyond December 31, 2021, the Company has assumed that it will be paying 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 its assessment of the realization of the foreign tax credit deferred tax asset. Furthermore, the Company does not rely on future U.S. source operating income in assessing future foreign tax credit realization due to its history of recent losses in the U.S. and therefore only relies on U.S. federal taxable temporary differences that it expects will reverse during the 10-year foreign tax credit carryover period. The Company’s assessment of realization of its foreign tax credit deferred tax asset is based on available evidence, including assumptions about future profitability of and distributions from MGM China, as well as its assumption concerning renewals of the five-year exemption from Macau’s 12% complementary tax on gaming profits. As a result, significant judgment is required in assessing the possible need for a valuation allowance and changes to such assumptions may have a material impact on the amount of the valuation allowance. For example, The Company projects that it will be able to realize a benefit and, hence, projects that it will record a deferred tax asset for foreign tax credits, net of valuation allowance, of approximately $182 million as of December 31, 2015 and has reflected this assumption in its annual effective tax rate for 2015. During the first and second quarters of 2015, the Company reassessed the foreign tax credit valuation allowance as a result of the continued decline in market conditions in Macau. The valuation allowance was increased by $81 million, of which $40 million was recorded as a direct reduction in income tax benefit during the nine months ended September 30, 2015, with the remainder impacting the effective tax rate for 2015. No material change was made to the foreign tax credit valuation allowance in the three months ended September 30, 2015. Recently issued accounting standards. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”), which is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2017. ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. Additionally, the new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company is currently assessing the impact that adoption of ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. In February 2015, the FASB issued Accounting Standards Update No. 2015-02, “Amendments to the Consolidation Analysis,” (“ASU 2015-02”), which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. ASU 2015-02 amends: the assessment of whether a limited partnership is a variable interest entity; the effect that fees paid to a decisionmaker have on the consolidation analysis; how variable interests held by a reporting entity’s related parties or de facto agents affect its consolidation conclusion; and for entities other than limited partnerships, clarifies how to determine whether the equity holders as a group have power over an entity. The Company is currently assessing the impact that adoption of ASU 2015-02 will have on its consolidated financial statements and footnote disclosures. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” (“ASU 2015-03”), which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The amortization of such costs will continue to be reported as interest expense. The Company does not believe the adoption of ASU 2015-03 will have a material effect on its financial statements or footnote disclosures. In August 2015, the FASB issued Accounting Standards Update No. 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements,” (“ASU 2015-15”), which should be adopted concurrent with ASU 2015-03. ASU 2015-15 allows for debt issuance costs related to line-of-credit agreements to be presented in the balance sheet as an asset, and for such costs to be amortized ratably over the term of the contract regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The amortization of such costs will continue to be reported as interest expense. The Company does not believe the adoption of ASU 2015-15 will have a material effect on its financial statements or footnote disclosures.

At September 30, 2015, the Company’s senior credit facility consisted of a $1.2 billion revolving credit facility, a $1.02 billion term loan A facility and a $1.70 billion term loan B facility. The revolving and term loan A facilities bear interest at LIBOR plus an applicable rate determined by the Company’s credit rating (2.75% as of September 30, 2015). The term loan B facility bears interest at LIBOR plus 2.50%, with a LIBOR floor of 1.00%. The revolving and term loan A facilities mature in December 2017 and the term loan B facility matures in December 2019. The term loan A and term loan B facilities are subject to scheduled amortization payments on the last day of each calendar quarter in an amount equal to 0.25% of the original principal balance. The Company permanently repaid $7 million and $21 million in the three and nine months ended September 30, 2015, respectively, in accordance with the scheduled amortization.

At September 30, 2015, the interest rate on the term loan A was 2.9% and the interest rate on the term loan B was 3.5%. The land and substantially all of the assets of MGM Grand Las Vegas, Bellagio and The Mirage secure up to $3.35 billion of obligations outstanding under the senior credit facility. In addition, the land and substantially all of the assets of New York-New York and Gold Strike Tunica secure the entire amount of the senior credit facility, and the land and substantially all of the assets of MGM Grand Detroit secure its $450 million of obligations as a co-borrower under the senior credit facility. In addition, the senior credit facility is secured by a pledge of the equity or limited liability company interests of the subsidiaries that own the pledged properties. The senior credit facility contains customary representations and warranties and customary affirmative and negative covenants. In addition, the senior credit facility requires the Company and its restricted subsidiaries (the “Restricted Group”) to maintain a minimum trailing four-quarter EBITDA (as defined in the senior credit facility) and limits the ability of the Restricted Group to make capital expenditures and investments. As of September 30, 2015 and through December 31, 2015, the Restricted Group is required to maintain a minimum EBITDA of $1.30 billion. The minimum EBITDA requirement increases to $1.35 billion for March 31, 2016 through December 31, 2016 and to $1.40 billion for March 31, 2017 and thereafter. EBITDA for the trailing four quarters ended September 30, 2015, calculated in accordance with the terms of the senior credit facility (which includes cash distributions from unconsolidated affiliates, such as the CityCenter distribution), was $1.65 billion. The senior credit facility limits the Restricted Group to capital expenditures of $500 million per fiscal year, with unused amounts in any fiscal year rolling over to the next fiscal year, but not any fiscal year thereafter. The Restricted Group’s total capital expenditures allowable under the senior credit facility for fiscal year 2015, after giving effect to unused amounts from 2014, was $794 million. In addition, the senior credit facility limits the Restricted Group’s ability to make investments subject to certain thresholds and other important exceptions. As of September 30, 2015, the Restricted Group was within the limit of capital expenditures and other investments for the 2015 calendar year. The senior credit facility provides for customary events of default, including, without limitation, (i) payment defaults, (ii) covenant defaults, (iii) cross-defaults to certain other indebtedness in excess of specified amounts, (iv) certain events of bankruptcy and insolvency, (v) judgment defaults in excess of specified amounts, (vi) the failure of any loan document by a significant party to be in full force and effect and such circumstance, in the reasonable judgment of the required lenders, is materially adverse to the lenders, or (vii) the security documents cease to create a valid and perfected first priority lien on any material portion of the collateral. In addition, the senior credit facility provides that a cessation of business due to revocation, suspension or loss of any gaming license affecting a specified amount of its revenues or assets, will constitute an event of default. MGM Grand Paradise credit facility. In June 2015, MGM China and MGM Grand Paradise, as co-borrowers, entered into a second amended and restated credit facility which consists of $1.55 billion of term loans and a $1.45 billion revolving credit facility. The term was extended for an eighteen month period to April 2019, with scheduled amortization payments of the term loans beginning in October 2017. The MGM Grand Paradise credit facility bears interest at a fluctuating rate per annum based on HIBOR plus a margin, initially set for a six month period at 1.75% per annum, but thereafter will range between 1.375% and 2.50% based on MGM China’s leverage ratio. The MGM Grand Paradise credit facility is secured by MGM Grand Paradise’s interest in the Cotai land use right, and MGM China, MGM Grand Paradise and their guarantor subsidiaries have granted a security interest in substantially all of their assets to secure the facility. The outstanding balance at September 30, 2015 was comprised solely of term loans. At September 30, 2015, the weighted average interest rate on the term loans was 1.99%. The MGM Grand Paradise credit facility contains customary representations and warranties, events of default, affirmative covenants and negative covenants, which impose restrictions on, among other things, the ability of MGM China and its subsidiaries to make investments, pay dividends and sell assets, and to incur additional liens. MGM China is also required to maintain compliance with a maximum consolidated total leverage ratio of 4.50 to 1.00 prior to the first anniversary of the MGM Cotai opening date and 4.00 to 1.00 thereafter, in addition to a minimum interest coverage ratio of 2.50 to 1.00. MGM China was in compliance with its credit facility covenants at September 30, 2015. Senior notes. The Company repaid its $875 million 6.625% senior notes in July 2015 at maturity. Convertible senior notes. In April 2015, holders of substantially all of the $1.45 billion in aggregate principle 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 principle 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 principle 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. Fair value of long-term debt. The estimated fair value of the Company’s long-term debt at September 30, 2015 was $13.1 billion. At December 31, 2014, the estimated fair value of the Company’s long-term debt was $15.1 billion. Fair value was estimated using quoted market prices for the Company’s senior notes and senior credit facility. Carrying value of the MGM Grand Paradise credit facility approximates fair value.

Segment Reporting [Abstract]
Segment Information	NOTE 11 — SEGMENT INFORMATION The Company’s management views each of its casino resorts as an operating segment. Operating segments are aggregated based on their similar economic characteristics, types of customers, types of services and products provided, the regulatory environments in which they operate, and their management and reporting structure. The Company’s principal operating activities occur in two geographic regions: the United States and Macau S.A.R. The Company has aggregated its operations into two reportable segments based on the similar characteristics of the operating segments within the regions in which they operate: wholly owned 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, net” in the following segment disclosures to reconcile to consolidated results. The Company’s management utilizes Adjusted Property EBITDA as the primary profit measure for its reportable segments. Adjusted Property EBITDA is a measure defined as Adjusted EBITDA before corporate expense and stock compensation expense related to the Omnibus Plan, which are not allocated to the reportable segments or each operating segment, as applicable. MGM China recognizes stock compensation expense related to the MGM China Plan which is included in the calculation of Adjusted EBITDA for MGM China. Adjusted EBITDA is a measure defined as earnings before interest and other non-operating income (expense), taxes, depreciation and amortization, preopening and start-up expenses and property transactions, net.

Basis of Presentation and Sig20

Basis of Presentation and Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Basis of presentation	Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2014 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014. In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments, which include only normal recurring adjustments, necessary to present fairly the Company’s interim financial statements. The results for such periods are not necessarily indicative of the results to be expected for the full year.
Fair value measurements	Fair value measurements. Fair value measurements affect the Company’s accounting and impairment assessments of its long-lived assets, investments in unconsolidated affiliates, cost method investments, assets acquired and liabilities assumed in an acquisition, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are observable inputs for similar assets; or Level 3 inputs, which are unobservable inputs. The Company uses Level 1 inputs for its long-term debt fair value disclosures. See Note 5.
Property and equipment	Property and equipment. As of September 30, 2015, the Company had accrued $11 million for property and equipment within “Accounts payable” and $38 million related to construction retention in “Other long-term obligations.” In addition, during the nine months ended September 30, 2015, the Company entered into capital leases with obligations of $12 million.
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. Due to a significant decrease in MGM China’s cash flows as well as a decline in the market capitalization of MGM China relative to its net book value, the Company performed an interim impairment test of goodwill related to the MGM China reporting unit in the second quarter of 2015. 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 reporting unit’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. In measuring 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. The results of the Company’s interim impairment test indicated the fair value of the MGM China reporting unit exceeded its carrying value by 9%. Therefore, the Company concluded that the carrying value of goodwill of $2.8 billion related to MGM China was not impaired based on the interim test. The Company has continued monitoring the results of this reporting unit and determined that circumstances did not exist that would require the Company to perform an interim impairment test in the third quarter of 2015.
Redeemable noncontrolling interest	Redeemable noncontrolling interest . In April 2015, MGM National Harbor issued non-voting membership interests in MGM National Harbor (“Membership Interests”) to Radio One, Inc. (“Radio One”), a noncontrolling interest party, for a purchase price of $ 5 million. In addition, Radio One was given the right to make one additional capital contribution of up to $35 million prior to July 1, 2016 for the purchase of additional Membership Interests. The Membership Interests provide for annual preferred distributions by MGM National Harbor to Radio One 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) Radio One will have the ability to require MGM National Harbor to purchase all or a portion of its Membership Interests for a purchase price that is based on a contractually agreed upon formula. Radio One also has the right to sell back all or a portion of its Membership Interest prior to such date if MGM National Harbor were to guarantee or grant liens to secure any indebtedness of the Company other than the indebtedness of MGM National Harbor. The Company has recorded the Membership Interests as “Redeemable noncontrolling interest” 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. Membership 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 will reflect any changes caused by such an adjustment in retained earnings.
Income tax provision	Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates , are reported in the interim period in which they occur. The Company’s effective income tax rate was (21.1)% and (21.4)% for the three and nine months ended September 30, 2015, respectively. The Company recognizes deferred tax assets, net of applicable reserves, related to tax loss and credit carryforwards and other temporary differences with a future tax benefit to the extent that realization of such benefit is more likely than not. Otherwise, a valuation allowance is applied. As of December 31, 2014, the scheduled future reversal of existing U.S. federal taxable temporary differences exceeded the scheduled future reversal of existing U.S. federal deductible temporary differences. Consequently, the Company no longer applies a valuation allowance against its domestic deferred tax assets other than its foreign tax credit deferred tax asset. The Company generates significant excess foreign tax credits each year that are attributable to the Macau Special Gaming Tax which is 35% of gross gaming revenue in Macau. Because MGM China is presently exempt from the Macau 12% complementary tax on gaming profits, the Company believes that payment of the Macau Special Gaming Tax qualifies as a tax paid in lieu of an income tax that is creditable against U.S. taxes. As long as the exemption from Macau’s 12% complementary tax on gaming profits continues and the Company continues to receive distributions from MGM China, the Company expects that it will generate excess foreign tax credits on an annual basis and that none of the excess foreign credits will be utilized until the exemption expires. Although the Company’s current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, the Company believes it will be entitled to receive a third five-year exemption from Macau based upon exemptions granted to the Company’s competitors in order to ensure non-discriminatory treatment among gaming concessionaires and subconcessionaires. For all periods beyond December 31, 2021, the Company has assumed that it will be paying 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 its assessment of the realization of the foreign tax credit deferred tax asset. Furthermore, the Company does not rely on future U.S. source operating income in assessing future foreign tax credit realization due to its history of recent losses in the U.S. and therefore only relies on U.S. federal taxable temporary differences that it expects will reverse during the 10-year foreign tax credit carryover period. The Company’s assessment of realization of its foreign tax credit deferred tax asset is based on available evidence, including assumptions about future profitability of and distributions from MGM China, as well as its assumption concerning renewals of the five-year exemption from Macau’s 12% complementary tax on gaming profits. As a result, significant judgment is required in assessing the possible need for a valuation allowance and changes to such assumptions may have a material impact on the amount of the valuation allowance. For example, The Company projects that it will be able to realize a benefit and, hence, projects that it will record a deferred tax asset for foreign tax credits, net of valuation allowance, of approximately $182 million as of December 31, 2015 and has reflected this assumption in its annual effective tax rate for 2015. During the first and second quarters of 2015, the Company reassessed the foreign tax credit valuation allowance as a result of the continued decline in market conditions in Macau. The valuation allowance was increased by $81 million, of which $40 million was recorded as a direct reduction in income tax benefit during the nine months ended September 30, 2015, with the remainder impacting the effective tax rate for 2015. No material change was made to the foreign tax credit valuation allowance in the three months ended September 30, 2015.
Recently issued accounting standards	Recently issued accounting standards. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers,” (“ASU 2014-09”), which is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2017. ASU 2014-09 outlines a new, single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. This new revenue recognition model provides a five-step analysis in determining when and how revenue is recognized. Additionally, the new model will require revenue recognition to depict the transfer of promised goods or services to customers in an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company is currently assessing the impact that adoption of ASU 2014-09 will have on its consolidated financial statements and footnote disclosures. In February 2015, the FASB issued Accounting Standards Update No. 2015-02, “Amendments to the Consolidation Analysis,” (“ASU 2015-02”), which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. ASU 2015-02 amends: the assessment of whether a limited partnership is a variable interest entity; the effect that fees paid to a decisionmaker have on the consolidation analysis; how variable interests held by a reporting entity’s related parties or de facto agents affect its consolidation conclusion; and for entities other than limited partnerships, clarifies how to determine whether the equity holders as a group have power over an entity. The Company is currently assessing the impact that adoption of ASU 2015-02 will have on its consolidated financial statements and footnote disclosures. In April 2015, the FASB issued Accounting Standards Update No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs,” (“ASU 2015-03”), which is effective for fiscal years, and interim periods within those years, beginning after December 15, 2015. ASU 2015-03 requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying value of the associated debt liability, consistent with the presentation of a debt discount. The amortization of such costs will continue to be reported as interest expense. The Company does not believe the adoption of ASU 2015-03 will have a material effect on its financial statements or footnote disclosures. In August 2015, the FASB issued Accounting Standards Update No. 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements,” (“ASU 2015-15”), which should be adopted concurrent with ASU 2015-03. ASU 2015-15 allows for debt issuance costs related to line-of-credit agreements to be presented in the balance sheet as an asset, and for such costs to be amortized ratably over the term of the contract regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. The amortization of such costs will continue to be reported as interest expense. The Company does not believe the adoption of ASU 2015-15 will have a material effect on its financial statements or footnote disclosures.

Complementary tax exemption expiration date		Dec. 31, 2016
Third exemption period from complementary tax assumed based on third exemption period granted to a competitor		5 years
Tax credit carryforward, description		The Company's current five-year exemption from the Macau 12% complementary tax on gaming profits ends on December 31, 2016, the Company believes it will be entitled to receive a third five-year exemption from Macau based upon exemptions granted to the Company's competitors in order to ensure non-discriminatory treatment among gaming concessionaires and subconcessionaires. For all periods beyond December 31, 2021, the Company has assumed that it will be paying 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 its assessment of the realization of the foreign tax credit deferred tax asset. Furthermore, the Company does not rely on future U.S source operating income in assessing future foreign tax credit realization due to its history of recent losses in the U.S. and therefore only relies on U.S. federal taxable temporary differences that it expects will reverse during the 10-year foreign tax credit carryover period.
