	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, primarily 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. Other Nevada operations include Circus Circus Reno, Gold Strike in Jean and Railroad Pass in Henderson. Along with its local partners, 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 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 has a land concession contract with the government of Macau to develop a second resort and casino on an approximately 17.8 acre site in Cotai, Macau (“MGM Cotai”). MGM Cotai will be an integrated casino, hotel and entertainment complex with up to 1,600 hotel rooms, 500 gaming tables and 2,500 slots. The total estimated project budget is $2.9 billion excluding development fees eliminated in consolidation, capitalized interest and land.
	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 3 for additional information related to CityCenter.
	The Company has 50% interests in Grand Victoria and Silver Legacy. 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. Silver Legacy is located in Reno, adjacent to Circus Circus Reno, and the other 50% is owned by Eldorado LLC.
	The Company seeks to leverage its management expertise and well-recognized brands through domestic and international expansion opportunities. The Company has entered into management agreements for non-gaming hotels, resorts and residential products in the Middle East, North Africa, India, the United States and, through its venture with Diaoyutai State Guesthouse, in the People’s Republic of China. In April 2014, the Company entered into a 50/50 limited liability company agreement with Hakkasan Hospitality, Inc., an affiliate of the Hakkasan group, to form MGM Hakkasan Hospitality, LLC, a Nevada limited liability company (“MGM Hakkasan”) to design, develop and manage luxury non-gaming hotels, resorts and residences under certain brands licensed from the Company and the Hakkasan Group. The Company will contribute all of the management agreements for non-gaming hotels, resorts and residential projects (outside of the greater China region) that are currently under development to MGM Hakkasan. The Company will continue to develop and manage properties in the greater China region through its venture with Diaoyutai State Guesthouse, including the MGM Grand Sanya on Hainan Island, in the People’s Republic of China, which opened in early 2012.
	The Maryland Video Lottery Facility Location Commission has awarded the Company the license to build and operate a world-class destination resort casino in Prince George’s County at National Harbor. Currently, the expected cost to develop and construct MGM National Harbor is approximately $1.0 billion, excluding capitalized interest and land related costs. The Company expects the resort to include a casino with approximately 3,600 slots, 160 table games including poker; a 300 suite hotel with luxury spa and rooftop pool; high end branded retail; fine and casual dining; a dedicated 3,000 seat theater venue; 35,000 square feet of meeting and event space; and a 5,000 space parking garage.
	The Company has two reportable segments: wholly owned domestic resorts and MGM China. See Note 9 for additional information about the Company’s segments.
	Borgata. The Company has a 50% economic interest in 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’s interest is held in trust and was offered for sale pursuant to its amended settlement agreement with the New Jersey Division of Gaming Enforcement and approved by the New Jersey Casino Control Commission (“CCC”). The terms of the amended settlement agreement previously mandated the sale by March 2014. The Company had the right to direct the sale through March 2013 (the “divesture period”), subject to approval of the CCC, and the trustee was responsible for selling the trust property during the following 12-month period (the “terminal sale period”). On February 13, 2013, the settlement agreement was further amended to allow the Company to re-apply to the CCC for licensure in New Jersey and to defer expiration of these periods pending the outcome of the licensure process. The Company has submitted its licensure request to the CCC and there can be no assurances that such request will be approved or with respect to the timing of the licensure process. If the CCC denies the Company’s licensure request, then the divesture period will immediately end, and the terminal sale period will immediately begin, which will result in the Company’s Borgata interest being disposed of by the trustee pursuant to the terms of the settlement agreement.
	The Company consolidates the trust because it is the sole economic beneficiary and accounts for its interest in Borgata under the cost method. The Company reviews its investment carrying value whenever indicators of impairment exist. As of March 31, 2014, the trust had $94 million of cash and investments, of which $78 million was held in U.S. treasury securities with maturities greater than three months but less than one year, and is recorded within “Prepaid expenses and other.”

Accounting Policies [Abstract]	'
Basis of Presentation and Significant Accounting Policies	'
	NOTE 2 — BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES
	Basis of presentation. As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2013 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	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 fair value of the Company’s treasury securities held by the Borgata trust was measured using Level 2 inputs. See Note 1; and

		•	The Company uses Level 1 inputs for its long-term debt fair value disclosures. See Note 4.
	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 (1.9%) and 57.4% for the three months ended March 31, 2014 and 2013, 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. Because of the Company’s history of recent losses in the United States, the Company does not rely on future United States sourced operating income in assessing the realization of its deferred tax assets. 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, the Company will generate excess foreign tax credits on an annual basis. Further, the Company currently estimates 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 both the measurement of its foreign deferred tax assets and liabilities as well as its future projections of foreign sourced income. As a result, 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 (“net deferred foreign tax credit asset”), of approximately $335 million as of December 31, 2014 and has reflected this assumption in its annual effective tax rate for 2014. Should the Company in a future period actually receive or be able to assume under the law a fourth five-year exemption, an additional valuation allowance would likely need to be provided on some or all of the net deferred foreign tax credit asset, resulting in an increase in the provision for income taxes in such period.

	Recently issued accounting standards. During the three months ended March 31, 2014, the Company implemented Financial Accounting Standards Board Accounting Standards Update No. 2013-11 (“ASU 2013-11”), which is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2013. ASU 2013-11 provides explicit guidance on the financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. As a result of implementing ASU 2013-11, the Company recorded a reduction in liability for unrecognized tax benefits and a corresponding reduction in deferred tax assets of $19 million in the three months ended March 31, 2014.

	Senior credit facility. At March 31, 2014, the Company’s senior credit facility consisted of $1.2 billion revolving credit facility, a $1.04 billion term loan A facility, and a $1.73 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 March 31, 2014). 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 in the first quarter of 2014 in accordance with the scheduled amortization. The Company had $1.2 billion of available borrowing capacity under its senior credit facility at March 31, 2014. At March 31, 2014, 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 to maintain a minimum trailing four-quarter EBITDA and limits the ability of the Company and its restricted subsidiaries to make capital expenditures and investments. At March 31, 2014 and June 30, 2014, the Company and its restricted subsidiaries are required to maintain a minimum EBITDA (as defined in the senior credit facility) of $1.10 billion. The minimum EBITDA increases to $1.20 billion for September 30, 2014 and December 31, 2014, with periodic increases thereafter. EBITDA for the trailing twelve months ended March 31, 2014, calculated in accordance with the terms of the senior credit facility, was $1.35 billion. The senior credit facility limits the Company and its restricted subsidiaries 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 Company’s total capital expenditures allowable under the senior credit facility for fiscal year 2014, after giving effect to unused amounts from 2013, was $681 million. In addition, the senior credit facility limits the Company’s ability to make investments subject to certain thresholds and other important exceptions. As of March 31, 2014, the Company and its restricted subsidiaries were within the limit of capital expenditures and other investments for the calendar year 2014.
	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 China credit facility. At March 31, 2014, the MGM China credit facility consisted of approximately $550 million of term loans and an approximately $1.45 billion revolving credit facility due October 2017. The credit facility is subject to scheduled amortization payments beginning in 2016. The outstanding balance at March 31, 2014 was comprised solely of term loans. The interest rate on the facility fluctuates annually based on HIBOR plus a margin, which ranges between 1.75% and 2.50%, based on MGM China’s leverage ratio. The margin was 1.75% at March 31, 2014. MGM China is a joint and several co-borrower with MGM Grand Paradise. MGM Grand Paradise’s interest in the Cotai land use right agreement will become collateral under the MGM China credit facility upon finalization of the appropriate government approvals. The material subsidiaries of MGM China continue to guarantee the facilities, and MGM China, MGM Grand Paradise and their guarantor subsidiaries have granted a security interest in substantially all of their assets to secure the amended facilities. The credit facility will be used for general corporate purposes and for the development of the Cotai project.
	The MGM China credit facility agreement 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 debt and 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 March 31, 2014.
	Senior notes. The Company repaid its $509 million 5.875% senior notes in February 2014 at maturity.
	Senior convertible notes. In April 2010, the Company issued $1.15 billion of 4.25% convertible senior notes due 2015 for net proceeds to the Company of $1.12 billion. The notes are general unsecured obligations of the Company and rank equally in right of payment with the Company’s other existing senior unsecured indebtedness. The notes are convertible at an initial conversion rate of approximately 53.83 shares of the Company’s common stock per $1,000 principal amount of the notes, representing an initial conversion price of approximately $18.58 per share of the Company’s common stock. In connection with the offering, the Company entered into capped call transactions to reduce the potential dilution of the Company’s stock upon conversion of the notes. The capped call transactions have a cap price equal to approximately $21.86 per share.
	In June 2011, the Company sold an additional $300 million in aggregate principal amount of 4.25% convertible senior notes due 2015 (the “Notes”) on terms that were consistent with those governing the Company’s existing convertible senior notes due 2015 for a purchase price of 103.805% of the principal amount. The Company received approximately $311 million in proceeds related to this transaction. The Notes were recorded at fair value determined by the trading price (105.872%) of the Company’s existing convertible notes on the date of issuance of the Notes, with the excess over the principal amount recorded as a premium to be recognized over the term of the Notes.
	Fair value of long-term debt. The estimated fair value of the Company’s long-term debt at March 31, 2014 was $14.7 billion. At December 31, 2013, the estimated fair value of the Company’s long-term debt was $14.9 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.

	NOTE 5 — COMMITMENTS AND CONTINGENCIES
	CityCenter construction litigation. In March 2010, Perini Building Company, Inc. (“Perini”), general contractor for CityCenter, filed a lawsuit in the Eighth Judicial District Court for Clark County, State of Nevada, against MGM MIRAGE Design Group (a wholly owned subsidiary of the Company which was the original party to the Perini construction agreement) and certain direct or indirect subsidiaries of CityCenter Holdings, LLC (the “CityCenter Owners”). Perini asserted that CityCenter was substantially completed, but the defendants failed to pay Perini approximately $490 million allegedly due and owing under the construction agreement for labor, equipment and materials expended on CityCenter. The complaint further charged the defendants with failure to provide timely and complete design documents, late delivery to Perini of design changes, mismanagement of the change order process, obstruction of Perini’s ability to complete the Harmon component, and fraudulent inducement of Perini to compromise significant amounts due for its general conditions. The complaint advanced claims for breach of contract, breach of the implied covenant of good faith and fair dealing, tortious breach of the implied covenant of good faith and fair dealing, unjust enrichment and promissory estoppel, and fraud and intentional misrepresentation. Perini seeks compensatory damages, punitive damages, attorneys’ fees and costs.
	In April 2010, Perini served an amended complaint in this case, which joins as defendants many owners of CityCenter residential condominium units (the “Condo Owner Defendants”), added a count for foreclosure of Perini’s recorded master mechanic’s lien against the CityCenter property in the amount of approximately $491 million, and asserted the priority of this mechanic’s lien over the interests of the CityCenter Owners, the Condo Owner Defendants and CityCenter lenders in the CityCenter property.
	The CityCenter Owners and the other defendants dispute Perini’s allegations and contend that the defendants are entitled to substantial amounts from Perini, including offsets against amounts claimed to be owed to Perini and its subcontractors and damages based on breach of their contractual and other duties to CityCenter, duplicative payment requests, non-conforming work, lack of proof of alleged work performance, defective work related to the Harmon, property damage and Perini’s failure to perform its obligations to pay certain subcontractors and to prevent filing of liens against CityCenter. Parallel to the court litigation, CityCenter management conducted an extra-judicial program for settlement of CityCenter subcontractor claims. CityCenter has resolved the claims of 219 first-tier Perini subcontractors (including the claims of any lower-tier subcontractors that might have claims through those first-tier subcontractors), with only three remaining for further proceedings along with trial of Perini’s claims and CityCenter’s Harmon-related counterclaim and other claims by CityCenter against Perini and its parent guarantor, Tutor Perini. Two of the remaining subcontractors are implicated in the defective work at the Harmon. In August 2013, Perini recorded an amended notice of lien reducing its lien to approximately $167 million.
	In November 2012, Perini filed a second amended complaint which, among other things, added claims against the CityCenter defendants of breach of contract (alleging that CityCenter’s Owner Controlled Insurance Program (“OCIP”) failed to provide adequate project insurance for Perini with broad coverages and high limits), and tortious breach of the implied covenant of good faith and fair dealing (alleging improper administration by CityCenter of the OCIP and Builders Risk insurance programs).
	In 2013, CityCenter reached a settlement agreement with certain professional service providers against whom it had asserted claims in this litigation for errors or omissions with respect to the CityCenter project, which settlement has been approved by the court. In April 2014, CityCenter settled for $55 million, net of deductible, its 2008 builder’s risk insurance claim for loss and damage with respect to the Harmon’s defective condition.
	Further, CityCenter and Perini have entered a settlement agreement which resolves most but not all of the components of Perini’s non-Harmon-related lien claim against CityCenter. The settlement established a stipulated value for Perini’s mechanic’s lien, which amount will not be paid until resolution of CityCenter’s damages claim for the Harmon and will be offset against any judgment CityCenter obtains against Perini for damages relating to construction of the Harmon. Pursuant to the parties’ stipulation, on February 24, 2014, Perini filed a revised lien for $174 million as the amount claimed by Perini and the remaining Harmon-related subcontractors. The discovery process continues. Trial of the remainder of Perini’s lien claim, the remaining subcontractors’ claims against CityCenter, and CityCenter’s counterclaims against Perini and certain subcontractors for defective work at the Harmon has been rescheduled to commence on September 23, 2014.
	CityCenter Owners and the other defendants will continue to vigorously assert and protect their interests in the Perini lawsuit. The Company believes it is probable that the CityCenter Owners and the other defendants will be liable for $140 million in connection with the non-Harmon settlement agreement and remaining claims in this lawsuit. Amounts determined to be owed would be funded in part under the Company’s completion guarantee which is discussed below. The Company does not believe it is reasonably possible it will be liable for any material amount in excess of its estimate of its probable liability. The Company’s estimate of its probable liability does not include any offset for amounts that may be recovered on its counterclaims against Perini and certain subcontractors for defective work at the Harmon.
	Please see below for further discussion on the Company’s completion guarantee obligation which may be impacted by the outcome of the above litigation and CityCenter’s extra-judicial settlement process.
	CityCenter completion guarantee. In October 2013, the Company entered into a third amended and restated completion and cost overrun guarantee, which is collateralized by substantially all of the assets of Circus Circus Las Vegas, as well as certain undeveloped land adjacent to that property. The terms of the amended and restated completion guarantee provide CityCenter the ability to utilize up to $72 million of net residential proceeds to fund construction costs, or to reimburse the Company for construction costs previously expended. As of March 31, 2014, CityCenter is holding approximately $72 million in a separate bank account representing the remaining condo proceeds available to fund completion guarantee obligations or be reimbursed to the Company. In accordance with the amended and restated completion guarantee, such amounts may only be used to fund construction lien obligations or to reimburse the Company once the Perini litigation is settled.
	As of March 31, 2014, the Company has funded $721 million under the completion guarantee and has accrued a liability of $104 million, which includes estimated litigation costs related to the resolution of disputes with contractors concerning the final construction costs and estimated amounts to be paid to contractors through the legal process related to the Perini litigation. The Company does not believe it is reasonably possible it could be liable for amounts in excess of what it has accrued. The Company’s estimated obligation has been offset by the $72 million of condominium proceeds received and held in escrow by CityCenter, which are available to fund construction lien claims upon the resolution of the Perini litigation. Also, the Company’s accrual reflects certain estimated offsets to the amounts claimed by the contractors. Moreover, the Company has not accrued for any contingent payments to CityCenter related to the Harmon component.
	Harmon demolition. In response to a request by the Clark County Building Division (the “Building Division”), CityCenter engaged an engineer to conduct an analysis, based on all available information, as to the structural stability of the Harmon under building-code-specified load combinations. On July 11, 2011, that engineer submitted the results of his analysis of the Harmon tower and podium in its current as-built condition. The engineer opined, among other things, that “[i]n a code-level earthquake, using either the permitted or current code specified loads, it is likely that critical structural members in the tower will fail and become incapable of supporting gravity loads, leading to a partial or complete collapse of the tower. There is missing or misplaced reinforcing steel in columns, beams, shear walls, and transfer walls throughout the structure of the tower below the twenty-first floor.” Based on this engineering opinion, the Building Division requested a plan of action from CityCenter. CityCenter informed the Building Division that it decided to abate the potential for structural collapse of the Harmon in the event of a code-level earthquake by demolishing the building, and enclosed a plan of action for demolition by implosion prepared by LVI Environmental Services of Nevada, Inc (“LVI”). CityCenter also advised that prior to undertaking the demolition plan of action, it would seek relief from a standing order of the district court judge presiding over the Perini litigation that prohibits alteration or destruction of the building without court approval. In addition, CityCenter supplied the foundational data for the engineering conclusions stated in the July 11, 2011 letter declaring the Harmon’s structural instability in the event of a code-level earthquake. On November 22, 2011, the Building Division required that CityCenter submit a plan to abate the code deficiencies discovered in the Harmon tower.
	In December 2011, CityCenter resubmitted to the Building Division the plan of abatement action prepared by LVI which was first submitted on August 15, 2011, and met with the Building Division about the requirements necessary to obtain demolition permits and approvals. As discussed above, the timing of the demolition of the Harmon is subject to rulings in the Perini litigation.
	The district court presiding over the Perini litigation had previously granted CityCenter’s motion to demolish the Harmon, but stayed the demolition to allow CityCenter an opportunity to conduct additional Phase 4 destructive testing at the Harmon following the court’s order prohibiting CityCenter’s structural engineering expert from extrapolating the results of pre-Phase 4 testing to untested portions of the building.
	In May 2013, CityCenter completed additional Phase 4 destructive testing of 468 structural elements at the Harmon, analysis of which data confirmed the existence of a wide variety of construction defects throughout the Harmon tower. In his June 2013 expert report CityCenter’s structural engineer opined that the additional test results and extrapolation thereof to untested portions of the building show that after a service-level earthquake (typically defined as an earthquake with a 50% chance of occurring in 30 years), the Harmon can be expected to sustain extensive damage and failure of many structural elements, and in a large earthquake, such as a building code-level earthquake, critical elements of the Harmon are likely to fail and lead to a partial or complete collapse of the tower. In April 2013, Perini’s structural engineering expert John A. Martin & Associates (“JAMA”) had sent a letter to the Building Division which declared in part that JAMA no longer believes that the Harmon Tower can be repaired to a code compliant structure, which condition JAMA attributed to CityCenter’s building testing. On July 18, 2013 CityCenter filed a renewed motion with the district court for permission to demolish the Harmon. On August 23, 2013, the court granted CityCenter’s motion, and CityCenter commenced planning for demolition of the building. On January 31, 2014, the court revoked its prior authorization of demolition of the Harmon, without prejudice to renewal of the application, on the grounds that CityCenter’s non-party builder’s risk insurer requested further testing in the building. That request for further testing was withdrawn pursuant to the insurer’s settlement of CityCenter’s Harmon 2008 policy claim. On April 22, 2014 the court granted CityCenter’s renewed application for permission to demolish the Harmon. The Clark County Building Department has issued the first in a series of permits required for demolition of this building. CityCenter is continuing to plan for a controlled deconstruction of the Harmon structure in accordance with the standards set by its expert consultants and the Clark County Building Department.
	The Company does not believe it would be responsible for funding any additional remediation efforts under the completion guarantee that might be required with respect to the Harmon; however, the Company’s view is based on a number of developing factors, including with respect to on-going litigation with CityCenter’s contractors, actions by local officials and other developments related to the CityCenter venture, all of which are subject to change.
	Cotai land concession contract. MGM Grand Paradise’s land concession contract for an approximate 17.8 acre site in Cotai, 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 March 31, 2014, MGM China had paid $86 million of the contract premium recorded within other long-term assets, net. Including interest on the six remaining semi-annual payments, MGM China has approximately $88 million remaining payable for the land concession contract. In addition, MGM Grand Paradise is required to pay the Macau government approximately $269,000 per year in rent during the course of development of the land and approximately $681,000 per year in rent once the development is completed. The annual rent is subject to review by the Macau government every five years. Under the terms of the land concession contract, MGM Grand Paradise is required to complete the development of the land by January 2018.
	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 $500 million, and the amount of available borrowings under the senior credit facility is reduced by any outstanding letters of credit. At March 31, 2014, the Company had provided $35 million of letters of credit. At March 31, 2014, MGM China had provided $39 million of guarantees under its credit facility.
	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.

	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 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 non-GAAP measure defined as Adjusted EBITDA before corporate expense and stock compensation expense related to the MGM Resorts stock option plan, which are not allocated to the reportable segments. MGM China recognizes stock compensation expense related to its stock compensation plan which is included in the calculation of Adjusted EBITDA for MGM China. Adjusted EBITDA is a non-GAAP 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.
	The following tables present the Company’s segment information:

MGM Branding and Development Holdings, Ltd., (together with its subsidiary MGM Development Services, Ltd, “MGM Branding and Development”), an entity included in the Company’s consolidated financial statements in which Ms. Pansy Ho indirectly holds a noncontrolling interest, entered into a brand license agreement with MGM China. MGM China pays a license fee to MGM Branding and Development equal to 1.75% of MGM China’s consolidated net revenue, subject to an annual cap of $43 million in 2014 with a 20% increase per annum during the agreement term. During the three months ended March 31, 2014 and 2013, MGM China incurred total license fees of $16 million and $13 million, respectively. Such amounts have been eliminated in consolidation.
	MGM China also entered into a development services agreement with MGM Branding and Development to provide certain development services to MGM China in connection with future expansion of existing projects and development of future resort gaming projects. Such services are subject to a development fee which is calculated separately for each resort casino property upon commencement of development. For each such property, the fee is 2.625% of project costs, to be paid in installments as certain benchmarks are achieved. Project costs are the total costs incurred for the design, development and construction of the casino, casino hotel, integrated resort and other related sites associated with each project, including costs of construction, fixtures and fittings, signage, gaming and other supplies and equipment and all costs associated with the opening of the business to be conducted at each project but excluding the cost of land and gaming concessions and financing costs. The development fee for MGM Cotai is subject to a cap of $24 million in 2014, which will increase by 10% per annum for each year during the term of the agreement. For the three months ended March 31, 2013, MGM China incurred $15 million of fees to MGM Branding and Development related to development services. Such amount was eliminated in consolidation. No fee was incurred during the three months ended March 31, 2014.

As permitted by the rules and regulations of the Securities and Exchange Commission, certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the Company’s 2013 annual consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.
	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 fair value of the Company’s treasury securities held by the Borgata trust was measured using Level 2 inputs. See Note 1; and

		•	The Company uses Level 1 inputs for its long-term debt fair value disclosures. See Note 4.
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 (1.9%) and 57.4% for the three months ended March 31, 2014 and 2013, 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. Because of the Company’s history of recent losses in the United States, the Company does not rely on future United States sourced operating income in assessing the realization of its deferred tax assets. 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, the Company will generate excess foreign tax credits on an annual basis. Further, the Company currently estimates 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 both the measurement of its foreign deferred tax assets and liabilities as well as its future projections of foreign sourced income. As a result, 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 (“net deferred foreign tax credit asset”), of approximately $335 million as of December 31, 2014 and has reflected this assumption in its annual effective tax rate for 2014. Should the Company in a future period actually receive or be able to assume under the law a fourth five-year exemption, an additional valuation allowance would likely need to be provided on some or all of the net deferred foreign tax credit asset, resulting in an increase in the provision for income taxes in such period.
Recently issued accounting standards	'
	Recently issued accounting standards. During the three months ended March 31, 2014, the Company implemented Financial Accounting Standards Board Accounting Standards Update No. 2013-11 (“ASU 2013-11”), which is effective for fiscal years, and interim periods within those years, beginning on or after December 15, 2013. ASU 2013-11 provides explicit guidance on the financial statement presentation of unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. As a result of implementing ASU 2013-11, the Company recorded a reduction in liability for unrecognized tax benefits and a corresponding reduction in deferred tax assets of $19 million in the three months ended March 31, 2014.
Segments 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 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 non-GAAP measure defined as Adjusted EBITDA before corporate expense and stock compensation expense related to the MGM Resorts stock option plan, which are not allocated to the reportable segments. MGM China recognizes stock compensation expense related to its stock compensation plan which is included in the calculation of Adjusted EBITDA for MGM China. Adjusted EBITDA is a non-GAAP 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.
