Accounting Policies [Abstract]
ORGANIZATION	NOTE 1—ORGANIZATION: The Mohegan Tribe of Indians of Connecticut (the “Mohegan Tribe” or the “Tribe”) established the Mohegan Tribal Gaming Authority (the “Authority”) in July 1995 with the exclusive authority to conduct and regulate gaming activities for the Tribe on Tribal lands and the non-exclusive authority to conduct such activities elsewhere. The Tribe is a federally-recognized Indian tribe with an approximately 595-acre reservation situated in Southeastern Connecticut, adjacent to Uncasville, Connecticut. Under the Indian Gaming Regulatory Act of 1988, federally-recognized Indian tribes are permitted to conduct full-scale casino gaming operations on tribal lands, subject to, among other things, the negotiation of a compact with the affected state. The Tribe and the State of Connecticut entered into a compact (the “Mohegan Compact”), which was approved by the United States Secretary of the Interior. The Authority is primarily engaged in the ownership, operation and development of gaming facilities. In October 1996, the Authority opened Mohegan Sun, a gaming and entertainment complex situated on an approximately 185-acre site on the Tribe’s reservation. The Authority is governed by a nine-member Management Board, whose members also comprise the Mohegan Tribal Council, the governing body of the Tribe. Any change in the composition of the Mohegan Tribal Council results in a corresponding change in the Authority’s Management Board. As of September 30, 2015, the following subsidiaries were wholly-owned by the Authority: Mohegan Basketball Club, LLC (“MBC”), Mohegan Golf, LLC (“Mohegan Golf”), Mohegan Lacrosse, LLC (“Mohegan Lacrosse”), Mohegan Commercial Ventures-PA, LLC (“MCV-PA”), Mohegan Ventures-Northwest, LLC (“Mohegan Ventures-NW”), Mohegan Ventures Wisconsin, LLC (“MVW”), MTGA Gaming, LLC (“MTGA Gaming”), Downs Lodging, LLC (“Downs Lodging”) and Mohegan Gaming Advisors, LLC (“Mohegan Gaming Advisors”). MBC owns and operates the Connecticut Sun, a professional basketball team in the Women’s National Basketball Association (the “WNBA”). MBC currently owns a 4.2% membership interest in WNBA, LLC. Mohegan Golf owns and operates the Mohegan Sun Golf Club in Southeastern Connecticut. Mohegan Lacrosse holds a 50% membership interest in New England Black Wolves, LLC (“NEBW”), which was formed with an unrelated third-party to own and operate the New England Black Wolves, a professional indoor lacrosse team in the National Lacrosse League (the “NLL”). MCV-PA holds a 0.01% general partnership interest in each of Downs Racing, L.P. (“Downs Racing”), Backside, L.P., Mill Creek Land, L.P. and Northeast Concessions, L.P. (collectively, along with MCV-PA, the “Pocono Subsidiaries”), while the Authority holds the remaining 99.99% limited partnership interest in each entity. Downs Racing owns and operates Mohegan Sun Pocono, a gaming and entertainment facility situated on an approximately 400-acre site in Plains Township, Pennsylvania, and several off-track wagering facilities located elsewhere in Pennsylvania (collectively, the “Pennsylvania Facilities”). The Authority views Mohegan Sun and the Pennsylvania Facilities as two separate operating segments. Mohegan Ventures-NW and a subsidiary of the Tribe hold 49.15% and 10.85% membership interests in Salishan-Mohegan, MVW holds a 100% membership interest in Wisconsin Tribal Gaming, LLC (“WTG”), which was formed to participate in the development of a proposed casino to be owned by the federally-recognized Menominee Indian Tribe of Wisconsin (the “Menominee Tribe”) and to be located in Kenosha, Wisconsin (the “Menominee Project”). MTGA Gaming holds a 100% membership interest in Mohegan Gaming & Hospitality, LLC (“MG&H”), an unrestricted subsidiary of the Authority. MG&H holds a 100% membership interest in Mohegan Resorts, LLC (“Mohegan Resorts”). Mohegan Resorts holds a 100% membership interest in Mohegan Resorts Mass, LLC, which was formed to pursue potential gaming opportunities in the Commonwealth of Massachusetts. Downs Lodging, an unrestricted subsidiary of the Authority, was formed to develop, finance and build Project Sunlight, a hotel and convention center located at Mohegan Sun Pocono. Mohegan Gaming Advisors, an unrestricted subsidiary of the Authority, was formed to pursue gaming opportunities outside the State of Connecticut, including management contracts and consulting agreements for casino and entertainment properties in the United States. Mohegan Gaming Advisors holds 100% membership interests in MGA Holding NJ, LLC (“MGA Holding NJ”) and MGA Gaming NJ, LLC (collectively, the “Mohegan NJ Entities”). The Mohegan NJ Entities were formed to pursue management contracts and consulting agreements in the State of New Jersey. MGA Holding NJ holds a 10% ownership interest in Resorts Casino Hotel in Atlantic City, New Jersey (“Resorts Atlantic City”). Mohegan Gaming Advisors also holds 100% membership interests in MGA Holding MA, LLC (“MGA Holding MA”) and MGA Gaming MA, LLC (“MGA Gaming MA”). MGA Holding MA holds a 100% membership interest in MGA Palmer Partners, LLC (“MGA Palmer Partners”). MGA Palmer Partners holds a 100% membership interest in Mohegan Sun Massachusetts, LLC (“Mohegan Sun Massachusetts”; Mohegan Sun Massachusetts, MGA Holding MA, MGA Gaming MA and MGA Palmer Partners are referred to collectively as the “Mohegan MA Entities”). The Mohegan MA Entities were formed to pursue potential gaming opportunities in the Commonwealth of Massachusetts. In addition, Mohegan Gaming Advisors holds a 100% membership interest in Inspire Integrated Resort Co., Ltd. (“Inspire Integrated Resort”). Inspire Integrated Resort was formed to pursue potential gaming opportunities in South Korea. Mohegan Gaming Advisors also holds 100% membership interests in MGNV, LLC (“MGNV”). MGNV was formed to pursue potential gaming, hospitality and entertainment opportunities in the State of Nevada. The Authority also holds 50% of the membership interests in MMCT Venture, LLC, which was formed with the Mashantucket Pequot Tribe (the “MPT”) to pursue potential additional gaming opportunities in the State of Connecticut.

Accounting Policies [Abstract]
BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2—BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Authority and its majority and wholly-owned subsidiaries and entities. In accordance with authoritative guidance issued by the Financial Accounting Standards Board (the “FASB”) pertaining to consolidation of variable interest entities, the accounts of Salishan-Mohegan are consolidated into the accounts of Mohegan Ventures-NW and the accounts of NEBW are consolidated into the accounts of Mohegan Lacrosse as Mohegan Ventures-NW and Mohegan Lacrosse are deemed to be the primary beneficiaries. In consolidation, all inter-company balances and transactions were eliminated. Change in Accounting Principles In April 2015, the FASB issued an accounting standard update to clarify the required presentation of debt issuance costs. The update requires that debt issuance costs related to non-revolving debt be presented in the balance sheet as a reduction to the carrying amount of the related debt rather than as an asset. This guidance is required to be applied on a retrospective basis and is effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority early adopted this guidance in the accompanying consolidated financial statements. The effect of adopting this guidance to the accompanying consolidated balance sheet as of September 30, 2014 was a $20.4 million decrease in other assets, net and long-term debt, net of current portion. The accompanying supplemental condensed consolidating financial statements within Note 16 also have been revised to reflect this adjustment. Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Authority to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The most significant estimates included in the accompanying consolidated financial statements relate to reserves for doubtful accounts, asset valuation, the liabilities associated with self-insurance and unredeemed Momentum Dollars, contingencies and litigation. Actual results could differ from these estimates. Cash and Cash Equivalents Cash and cash equivalents consist of deposits that can be redeemed on demand and investments with original maturities of less than 90 days. Cash equivalents are carried at cost, which approximates market value. Cash and cash equivalents include all operating cash and in-house funds. Restricted Cash Restricted cash consists of deposits that are contractually restricted as to their withdrawal or use. Restricted cash primarily includes cash held by Downs Racing pursuant to the Pennsylvania Race Horse Development and Gaming Act and Pennsylvania state statutes. The Pennsylvania Race Horse Development and Gaming Act requires Downs Racing to deposit a percentage of gross revenues from slot machines into a separate interest bearing account for the benefit of horsemen and breeders. In addition, Pennsylvania state statutes require Downs Racing to deposit net amounts received from the sale of lottery tickets into a separate designated account. Receivables Accounts Receivable Accounts receivable consists primarily of casino receivables, which represent credit extended to approved casino patrons, and hotel and other non-gaming receivables. The Authority maintains a reserve for doubtful collection, which is based on the Authority’s estimate of the probability that these receivables will be collected. The Authority assesses the adequacy of this reserve by continuously evaluating historical experience, creditworthiness of the related patron and all other available information. Future business or economic trends could affect the collectability of these receivables and the related reserve. Long-Term Receivables Long-term receivables consist primarily of receivables from affiliates and others. Receivables from affiliates, which are included in receivables, net, and other assets, net, in the accompanying consolidated balance sheets, consist of reimbursable costs and expenses advanced by Salishan-Mohegan on behalf of the Cowlitz Tribe for the Cowlitz Project (refer to Note 12) and WTG on behalf of the Menominee Tribe for the Menominee Project (refer to Note 13). As of September 30, 2015, the Salishan-Mohegan receivables are payable upon: (1) the related property being taken into trust by the United States Department of the Interior and (2) the receipt of necessary financing for the development of the proposed casino. Due to the uncertainty in the development of the Cowlitz Project, the Authority maintains a reserve for doubtful collection of the Salishan-Mohegan receivables, which is based on the Authority’s estimate of the probability that the receivables will be collected. The Authority assesses the reserve for doubtful collection of the Salishan-Mohegan receivables for adequacy on a quarterly basis. Future developments in the construction and opening of the proposed casino or other matters affecting the Cowlitz Project could affect the collectability of the Salishan-Mohegan receivables and the related reserve. The WTG receivables are fully reserved. The WTG receivables are payable upon the receipt of necessary financing for the development of the proposed casino, subject to certain conditions. Receivables from others, which are primarily included in other assets, net, in the accompanying consolidated balance sheets, consist primarily of funds loaned to third-parties in connection with various diversification projects. Receivables from others also include a loan to a tenant at Mohegan Sun. The Authority maintains a reserve for doubtful collection of receivables from others, which is based on the Authority’s estimate of the probability that these receivables will be collected considering historical experience, creditworthiness of the related third-parties and tenant and all other available information. The following table presents a reconciliation of long-term receivables, including current portions, and the related reserves for doubtful collection of these long-term receivables (in thousands): Long-Term Receivables Affiliates Others Total Balance, September 30, 2014 $ 66,596 $ 2,612 $ 69,208 Additions: Issuance of affiliate advances and other loans, including interest receivable 13,980 135 14,115 Cowlitz Project land value transfer (2) 19,951 — 19,951 Deductions: Payments received — (157 ) (157 ) Adjustments — (779 ) (779 ) Balance, September 30, 2015 $ 100,527 $ 1,811 $ 102,338 (1) Includes current portions of $19.6 million and $901,000 as of September 30, 2015 and 2014, respectively. Also includes interest receivable of $43.4 million and $35.7 million as of September 30, 2015 and 2014, respectively. The WTG receivables no longer accrue interest pursuant to a release and reimbursement agreement entered into in September 2010. (2) Relates to the transfer of land for the proposed Cowlitz Project site between Salishan-Mohegan and the Cowlitz Tribe (refer to Note 12). Reserves for Doubtful Collection of Long-Term Receivables Affiliates Others Total Balance, September 30, 2014 $ 26,833 $ 796 $ 27,629 Additions: Charges to bad debt expense 4,195 35 4,230 Deductions: Adjustments — (789 ) (789 ) Balance, September 30, 2015 $ 31,028 $ 42 $ 31,070 Inventories Inventories are stated at the lower of cost or market value and consist primarily of food and beverage, retail, hotel and operating supplies. Cost is determined using the average cost method. The Authority reduces the carrying value of slow-moving inventory to net realizable value, based on the Authority’s estimate of the amount of inventory that may not be utilized in future operations. Future business trends could affect the timely use of inventories. Property and Equipment Property and equipment are stated at cost. Depreciation is recognized over the estimated useful lives of the assets, other than land, on a straight-line basis. Leasehold improvements are amortized over the shorter of the lease terms or the estimated useful lives of the improvements. Estimated useful lives by asset categories are as follows: Buildings and land improvements 40 years Furniture and equipment 3 - 7 years The costs of significant improvements are capitalized. Costs of normal repairs and maintenance are expensed as incurred. Gains or losses on disposition of property and equipment are reflected in the accompanying consolidated financial statements. Property and equipment are assessed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If it is determined that the carrying amounts may not be recoverable based on current and future levels of income and cash flows, as well as other factors, an impairment loss will be recognized at such time. During its fourth quarter ended September 30, 2014, the Authority further re-evaluated its plans with respect to the development of the new hotel element of its suspended Project Horizon expansion, which included a hotel to be developed and owned by an instrumentality of the Tribe, as well as a third-party developed and owned retail center, and, based on new design plans, including the final location of the planned hotel, determined that certain design and earthwork related assets did not have any future benefit to the Authority. Accordingly, the Authority recognized a related $5.0 million impairment charge, which was recorded in the accompanying consolidated statement of loss for the fiscal year ended September 30, 2014. In March 2015, the Mohegan Tribal Finance Authority (“MTFA”), a wholly-owned instrumentality of the Tribe, agreed to develop the planned hotel. Concurrent with this transaction, the Authority re-evaluated the planned third-party developed and owned retail center, including master planning costs, and determined that these elements of the project were no longer feasible. Accordingly, the related assets did not have any future benefit to the Authority, and, during its second quarter ended March 31, 2015, the Authority recognized a related $2.5 million impairment charge, which was recorded in the accompanying consolidated statement of income for the fiscal year ended September 30, 2015. There are no assets remaining related to the suspended elements of Project Horizon (refer to Note 4). As of September 30, 2015 and 2014, the Authority assessed its property and equipment for any additional impairment and determined that no additional impairment existed. Capitalized Interest Interest costs incurred in connection with major development and construction projects are capitalized and included in the cost of the related project. Under instances where no debt is directly incurred in connection with a project, interest is capitalized on amounts expended on the project utilizing the weighted-average interest cost of the Authority’s outstanding borrowings. Capitalization of interest ceases when a project is substantially completed or development activity is suspended for an extended period of time. Goodwill In accordance with authoritative guidance issued by the FASB pertaining to goodwill, the goodwill associated with the acquisition of the Pennsylvania Facilities is not subject to amortization, but is assessed at least annually for impairment by comparing its fair value to its carrying value. The fair value is determined utilizing an income approach based on projected discounted cash flows from the Pennsylvania Facilities, exclusive of capital expenditures requirements. If the carrying value of the goodwill exceeds its fair value, an impairment loss will be recognized to the extent that the carrying value of the goodwill exceeds its implied fair value. The income approach requires the Authority to make assumptions regarding future revenues and expenses, discount rates and the terminal value based on a market multiple of the Pennsylvania Facilities. As of September 30, 2015 and 2014, the Authority assessed the goodwill for impairment and determined that no impairment existed. If any of the following occurs, the goodwill may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from the Pennsylvania Facilities are not achieved, (2) if the discount rate increases, (3) if terminal growth rates decrease or (4) if market multiples decrease. Other Intangible Assets Intangible assets relate primarily to the Pennsylvania Facilities, Mohegan Sun, MBC, Mohegan Lacrosse and Mohegan Golf. In connection with the acquisition of the Pennsylvania Facilities, the Authority recorded a slot machine license intangible asset of $214.0 million. In October 2006, a one-time slot machine license fee of $50.0 million was paid to the Pennsylvania Gaming Control Board (the “PGCB”) and added to the existing slot machine license intangible asset. In June 2010, a one-time table game certificate fee of $16.5 million was paid to the PGCB and classified as an intangible asset. The slot machine license and table game certificate intangible assets, with indefinite useful lives, are assessed as a single unit of accounting at least annually for impairment by comparing the fair value of the recorded assets to their carrying value. Their fair value is determined utilizing an income approach based on projected discounted cash flows from the Pennsylvania Facilities, exclusive of a required rate of return of all other assets and exclusive of capital expenditures requirements. If the carrying value exceeds the fair value, an impairment loss will be recognized to the extent that the carrying value exceeds the fair value. The income approach requires the Authority to make assumptions regarding future revenues and expenses, discount rates and the terminal value based on a perpetual growth rate of the Pennsylvania Facilities. As of September 30, 2015 and 2014, the Authority assessed the intangible assets for impairment and determined that no impairment existed. If any of the following occurs, the intangible assets may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from the Pennsylvania Facilities are not achieved, (2) if the discount rate increases or (3) if the terminal value decreases. In connection with a relinquishment agreement (refer to Note 11), Trading Cove Associates (“TCA”) granted the Authority an exclusive, irrevocable, perpetual, world-wide and royalty-free license with respect to trademarks and other similar rights, including the “Mohegan Sun” name. The Mohegan Sun trademark intangible asset of $119.7 million is deemed to have an indefinite useful life and is assessed at least annually for impairment by comparing its fair value to its carrying value. The fair value is determined utilizing the income approach – relief from royalty method based on projected revenues from Mohegan Sun and Mohegan Sun Pocono. If the carrying value exceeds the fair value, an impairment loss will be recognized to the extent that the carrying value exceeds the fair value. The income approach requires the Authority to make assumptions regarding future revenues, discount rates, royalty rate and the terminal value based on a perpetual growth rate of Mohegan Sun and Mohegan Sun Pocono. As of September 30, 2015 and 2014, the Authority assessed the Mohegan Sun trademark for impairment and determined that no impairment existed. If any of the following occurs, the Mohegan Sun trademark may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from Mohegan Sun and Mohegan Sun Pocono are not achieved, (2) if the discount rate increases or (3) if the perpetual growth rate decreases. In connection with the acquisitions of the WNBA and NLL franchises and the assets of Pautipaug Country Club Inc., the Authority recorded franchise value intangible assets and a membership intangible asset, respectively. These intangible assets, with definite useful lives, are assessed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of September 30, 2015 and 2014, the Authority assessed these intangible assets for impairment and determined that no impairment existed. Debt Issuance Costs, Discounts and Premiums Debt issuance costs incurred in connection with the issuance of revolving debt are capitalized and amortized to interest expense based on the related debt agreements on a straight-line basis. Unamortized amounts are included in other assets, net, in the accompanying consolidated balance sheets. Debt issuance costs incurred in connection with the issuance of non-revolving debt are recorded as a reduction to the carrying amount of the related debt and amortized to interest expense based on the effective interest method. Premiums received in connection with the issuance of debt are recorded as an increase to the carrying amount of the related debt and amortized to interest expense based on the effective interest method. Self-insurance Accruals The Authority is self-insured up to certain limits for costs associated with workers’ compensation, general liability and employee medical coverage. Insurance claims and reserves include accruals of estimated settlements of known claims, as well as accruals of estimates of incurred but not reported claims. These accruals are included in other current liabilities in the accompanying consolidated balance sheets. In estimating self-insurance accruals, the Authority considers historical loss experiences and expected levels of costs per claim. Claims are accounted for based on estimates of undiscounted claims, including claims incurred but not reported. The Authority believes that this method provides a consistent and effective way to measure these liabilities; however, changes in health care costs, accident frequency and severity and other factors could materially impact estimated liabilities. The Authority continuously monitors estimates and makes adjustments when necessary. Unredeemed Momentum Dollars The Authority maintains an accrual for unredeemed Momentum Dollars. This accrual is based on the estimated cost of Momentum Dollars expected to be redeemed as of the respective balance sheet date. The Authority assesses the adequacy of this accrual by periodically evaluating historical redemption experiences and projected trends related to the accrual. Actual results could differ from these estimates. Base Jackpots Base jackpots represent the fixed minimum amount of payouts from slot machines for a specific combination. The Authority recognizes base jackpots as reductions to revenues when it becomes obligated to pay such jackpots. Fair Value of Financial Instruments The fair value amounts presented below are reported to satisfy disclosure requirements pursuant to authoritative guidance issued by the FASB pertaining to disclosures about fair values of financial instruments and are not necessarily indicative of amounts that the Authority could realize in a current market transaction. The Authority applies the following fair value hierarchy, which prioritizes the inputs utilized to measure fair value into three levels: • Level 1 - Quoted prices for identical assets or liabilities in active markets; • Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets or valuations based on models where the significant inputs are observable or can be corroborated by observable market data; and • Level 3 - Valuations based on models where the significant inputs are unobservable. The unobservable inputs reflect the Authority’s estimates or assumptions that market participants would utilize in pricing such assets or liabilities. The Authority’s assessment of the significance of a particular input requires judgment and may affect the valuation of financial assets and liabilities and their placement within the fair value hierarchy. The carrying amount of cash and cash equivalents, receivables, trade payables and promissory notes and certain credit facilities approximates fair value. The estimated fair value of the Authority’s financing facilities and notes were as follows (in thousands): September 30, 2015 Carrying Value Fair Value Senior Secured Credit Facility – Revolving $ 21,000 $ 20,575 Senior Secured Credit Facility – Term Loan A $ 109,613 $ 109,811 Senior Secured Credit Facility – Term Loan B $ 792,078 $ 802,711 2013 9 3/4% Senior Unsecured Notes $ 577,667 $ 596,700 2012 11% Senior Subordinated Notes $ 98,939 $ 103,446 The estimated fair values of the Authority’s financing facilities and notes were based on Level 2 inputs (quoted market prices or prices of similar instruments) on or about September 30, 2015. Revenue Recognition The Authority recognizes gaming revenues as amounts wagered less prizes paid out. Revenues from food and beverage, hotel, retail, entertainment and other services are recognized at the time such service is performed. Minimum rental revenues are recognized on a straight-line basis over the terms of the related leases. Percentage rental revenues are recognized in the periods in which the tenants exceed their respective percentage rent thresholds. Promotional Allowances The Authority operates a program, without membership fees, for patrons at Mohegan Sun, Mohegan Sun Pocono and its managed property, Resorts Atlantic City. This program provides complimentary food and beverage, hotel, retail, entertainment and other amenities to patrons based on Momentum Dollars that are awarded for patrons’ gaming activities. Momentum Dollars may be utilized to purchase, among other things, items at restaurants and retail stores located within Mohegan Sun, Mohegan Sun Pocono and Resorts Atlantic City. Momentum Dollars may also be utilized at The Shops at Mohegan Sun and the Mohegan Sun gasoline and convenience center, as well as to purchase hotel services and tickets to entertainment events held at facilities located at Mohegan Sun, Mohegan Sun Pocono and Resorts Atlantic City. The retail value of complimentary items redeemed at facilities operated by the Authority is included in gross revenues and then deducted as promotional allowances to arrive at net revenues. The cost associated with reimbursing third-parties for the value of complimentary items redeemed at third-party outlets is included in gaming costs and expenses. In addition, the Authority offers ongoing promotional coupons to patrons for the purchase of food and beverage, hotel and retail amenities offered at Mohegan Sun and Mohegan Sun Pocono. The retail value of coupons redeemed at facilities operated by the Authority is included in gross revenues and then deducted as promotional allowances to arrive at net revenues. The cost associated with reimbursing third-parties for the value of coupons redeemed at third-party outlets is included in gaming costs and expenses. The retail value of promotional allowances was included in gross revenues as follows (in thousands): For the Fiscal Years Ended September 30, 2015 September 30, 2014 September 30, 2013 Food and beverage $ 42,192 $ 43,264 $ 38,390 Hotel 15,142 14,721 13,799 Retail, entertainment and other 40,012 40,959 43,668 Total $ 97,346 $ 98,944 $ 95,857 The estimated cost of promotional allowances was included in gaming costs and expenses as follows (in thousands): For the Fiscal Years Ended September 30, 2015 September 30, 2014 September 30, 2013 Food and beverage $ 35,122 $ 37,936 $ 34,194 Hotel 8,398 8,979 7,216 Retail, entertainment and other 35,559 36,772 40,167 Total $ 79,079 $ 83,687 $ 81,577 In certain circumstances, the Authority also offers discounts on patron losses and cash inducements at Mohegan Sun and Mohegan Sun Pocono, which are recognized as reductions to gaming revenues. Reductions to gaming revenues related to discounts provided on patron losses totaled $9.7 million, $12.2 million and $11.0 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. Reductions to gaming revenues related to Momentum Dollars redeemed for cash totaled $1.4 million, $1.3 million and $1.4 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. Gaming Costs and Expenses Gaming costs and expenses primarily include portions of gaming revenues that must be paid to the State of Connecticut and the PGCB. Gaming costs and expenses also include, among other things, payroll costs, expenses associated with the operation of slot machines, table games, poker, live harness racing and racebook, certain marketing expenditures and promotional expenses related to Momentum Dollar and coupon redemptions. Advertising Costs and Expenses Production costs are expensed the first time the advertisement takes place. Prepaid rental fees associated with billboard advertisements are capitalized and amortized over the terms of the related rental agreements. Advertising costs and expenses totaled $27.0 million, $26.7 million and $28.2 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. As of September 30, 2015 and 2014, prepaid advertising was $432,000 and $142,000, respectively. Corporate Costs and Expenses Corporate costs and expenses represent an allocation of certain governmental and administrative costs, payroll costs, professional fees and various other expenses not directly related to the Authority’s operations at Mohegan Sun or Mohegan Sun Pocono. In addition, Corporate costs and expenses include costs associated with various gaming diversification efforts, which are expensed as incurred, except when reimbursable by third-parties. Pre-Opening Costs and Expenses In accordance with authoritative guidance issued by the FASB pertaining to the reporting on the costs of start-up activities, pre-opening costs and expenses are expensed as incurred. Investments in Unconsolidated Affiliates The Authority, through its indirect wholly-owned subsidiary, MGA Holding NJ, holds a 10% ownership interest in Resorts Atlantic City and its associated gaming activities, including online gaming in the State of New Jersey. The Authority’s investment in Resorts Atlantic City is accounted for under the equity method as the Authority has significant influence. Income Taxes The Tribe is a sovereign Indian nation with independent legal jurisdiction over its people and land. Like other sovereign governments, the Tribe and its entities, including the Authority, are not subject to federal, state or local income taxes. Seasonality The gaming market in the Northeastern United States is seasonal in nature, with peak gaming activities often occurring at Mohegan Sun and Mohegan Sun Pocono during the months of May through August. Accordingly, the Authority’s operating results for the fiscal year ended September 30, 2015 are not necessarily indicative of operating results for interim periods. New Accounting Standards In May 2014, the FASB issued an accounting standard update on revenue recognition that will be applied to all contracts with customers. The update requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance will be required to be applied on a retrospective basis, using one of two methodologies, and was to be effective for annual reporting periods beginning after December 15, 2016, with early application not being permitted. However, in July 2015, the FASB deferred the effective date by one year. This guidance will now be effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods thereafter. Entities are permitted to adopt the guidance as of the original effective date. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations. In August 2014, the FASB issued an accounting standard update which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The update requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. It also requires management to provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. This guidance will be required for annual reporting periods ending after December 15, 2016, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations. In February 2015, the FASB issued an accounting standards update which amends existing requirements applicable to reporting entities that are required to evaluate whether certain legal entities should be consolidated. This guidance will be required to be applied either on a retrospective or modified retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.

The Authority did not recognize any capitalized interest for the fiscal year ended September 30, 2015. Capitalized interest totaled $735,000 and $2.0 million for the fiscal years ended September 30, 2014 and 2013, respectively. In September 2008, the Authority suspended certain elements of its Project Horizon expansion due to a slowdown in business volumes and uncertainties in the financial markets. Costs incurred on the suspended elements related to excavation and foundation work for a planned podium and new hotel tower, as well as professional fees for design and architectural work. During its fourth quarter ended September 30, 2014, the Authority further re-evaluated its plans with respect to the development of the new hotel element of the project, which then included a hotel to be developed and owned by an instrumentality of the Tribe, as well as a third-party developed and owned retail center, and, based on new design plans, including the final location of the planned hotel, determined that certain design and earthwork related assets did not have any future benefit to the Authority. Accordingly, the Authority recognized a related $5.0 million impairment charge, which was recorded in the accompanying consolidated statement of loss for the fiscal year ended September 30, 2014. In March 2015, the MTFA agreed to develop the planned hotel. The Authority received approximately $1.3 million as payment for the carrying value of the remaining hotel related assets which were transferred to MTFA. Concurrent with this transaction, the Authority re-evaluated the planned third-party developed and owned retail center, including master planning costs, and determined that these elements of the project were no longer feasible. Accordingly, the related assets did not have any future benefit to the Authority, and, during its second quarter ended March 31, 2015, the Authority recognized a related $2.5 million impairment charge, which was recorded in the accompanying consolidated statement of income for the fiscal year ended September 30, 2015. There are no assets remaining related to the suspended elements of Project Horizon.

On August 11, 2015, the Authority completed a series of refinancing transactions including the redemption of $175.0 million of its 2012 Senior Subordinated Notes with proceeds from the issuance of an additional $90.0 million of loans under its Term Loan B Facility and an additional $85.0 million of 2013 Senior Unsecured Notes (all further discussed below). The Authority incurred approximately $6.6 million in costs in connection with these refinancing transactions, consisting primarily of consulting, legal, advisory and amendment fees. Previously deferred debt discounts and debt issuance costs totaling $2.3 million, as well as $1.7 million in new transaction costs, were expensed and recorded as a loss on early extinguishment of debt in the accompanying consolidated statement of income for the fiscal year ended September 30, 2015. Of the remaining $4.9 million in new transaction costs, $4.7 million was recorded as a reduction to the carrying amount of the related debt and included in long-term debt, net of current portion, in the accompanying consolidated balance sheet as of September 30, 2015 and will be amortized over the term of the related debt. The remaining $219,000 in new costs was capitalized and included in other assets, net, in the accompanying consolidated balance sheet as of September 30, 2015 and will be amortized over the term of the related debt. Senior Secured Credit Facilities In November 2013, the Authority entered into a loan agreement among the Authority, the Tribe, the Guarantors as defined below, RBS Citizens, N.A., as Administrative and Collateral Agent, and the other lenders and financial institutions party thereto, providing for $955.0 million in aggregate principal amount of senior secured credit facilities (the “Senior Secured Credit Facilities”), comprised of a $100.0 million senior secured revolving credit facility (the “Revolving Facility”), a $125.0 million senior secured term loan A facility (the “Term Loan A Facility”) and a $730.0 million senior secured term loan B facility (the “Term Loan B Facility”). The Senior Secured Credit Facilities mature on June 15, 2018, subject to extension based on the satisfaction of certain conditions to November 19, 2018 (in the case of the Revolving Facility and the Term Loan A Facility) and November 19, 2019 (in the case of the Term Loan B Facility). On August 11, 2015, the Authority entered into an increase joinder and amendment agreement among the Authority, the Tribe, the Guarantors as defined below, Citizens Bank, N.A., as Administrative Agent, and the lenders party thereto, amending the Senior Secured Credit Facilities. Pursuant to the amendment, the Authority borrowed $90.0 million of increase term B loans on the same terms as the existing term B loans under Term Loan B Facility. The net proceeds from this transaction were used to redeem outstanding 2012 Senior Subordinated Notes (further discussed below). The Term Loan A Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 5.0% of the original principal amount for the first year after the closing date, 7.5% of the original principal amount for the second year after the closing date and 10.0% of the original principal amount in each year thereafter, with the balance payable on the maturity date of the Term Loan A Facility. The Term Loan B Facility amortizes in equal quarterly installments in an aggregate annual amount equal to 1.0% of the original principal amount. Amortization of the Term Loan A Facility and Term Loan B Facility began with the first full fiscal quarter after the closing date. As of September 30, 2015, amounts outstanding under the Revolving Facility, Term Loan A Facility and Term Loan B Facility totaled $21.0 million, $111.7 million and $807.0 million, respectively. As of September 30, 2015, letters of credit issued under the Revolving Facility totaled $3.0 million, of which no amount was drawn. Inclusive of letters of credit, which reduce borrowing availability under the Revolving Facility, and after taking into account restrictive financial covenant requirements, the Authority had approximately $76.0 million of borrowing capacity under its Revolving Facility and Line of Credit as of September 30, 2015. Borrowings under the Senior Secured Credit Facilities incur interest as follows: (i) for base rate loans under the Revolving Facility and Term Loan A Facility, a base rate equal to the highest of (a) the prime rate, (b) the federal funds rate plus 50 basis points and (c) the one-month LIBOR rate plus 100 basis points (the highest of (a), (b) and (c), the “base rate”), plus a leverage-based margin of 250 to 350 basis points; (ii) for Eurodollar rate loans under the Revolving Facility and Term Loan A Facility, the applicable LIBOR rate plus a leverage-based margin of 350 to 450 basis points; (iii) for base rate loans under the Term Loan B Facility, the base rate (subject to a 2.0% floor) plus 350 basis points; and (iv) for Eurodollar rate loans under the Term Loan B Facility, the applicable LIBOR rate (subject to a 1.0% floor) plus 450 basis points. The Authority is also required to pay a leverage-based commitment fee of between 37.5 and 50 basis points for unused commitments under the Revolving Facility. Interest on base rate loans is payable quarterly in arrears. Interest on Eurodollar rate loans of three months or less is payable at the end of each applicable interest period and for Eurodollar rate loans of more than three months, interest is payable at intervals of three months duration after the beginning of such interest period. As of September 30, 2015, the $21.0 million outstanding under the Revolving Facility was comprised of an $11.0 million base rate loan based on a base rate of 3.25% plus 300 basis points and $10.0 million in Eurodollar rate loans based on a Eurodollar rate of 0.20% plus 400 basis points. The commitment fee was 0.50% as of September 30, 2015. As of September 30, 2015, the $111.7 million outstanding under the Term Loan A Facility was based on a Eurodollar rate of 0.33% plus 400 basis points. As of September 30, 2015, the $807.0 million outstanding under the Term Loan B Facility was based on the Eurodollar rate floor of 1.0% plus 450 basis points. As of September 30, 2015, the effective interest rates of amounts outstanding under the Term Loan A Facility and Term Loan B Facility, after taking into account discounts and debt issuance costs, were 5.30% and 6.24%, respectively. As of September 30, 2015 and 2014, accrued interest, including commitment fees, on the Senior Secured Credit Facilities was $195,000 and $212,000, respectively. The Authority’s obligations under the Senior Secured Credit Facilities are fully and unconditionally guaranteed, jointly and severally, by the Pocono Subsidiaries, MBC, Mohegan Golf, Mohegan Ventures-NW, MVW, WTG and MTGA Gaming (collectively, the “Guarantors”). The Senior Secured Credit Facilities are collateralized by a first priority lien on substantially all of the Authority’s property and assets and those of the Guarantors (other than MBC), including the assets that comprise Mohegan Sun Pocono and a leasehold mortgage on the land and improvements that comprise Mohegan Sun (the Authority and the Guarantors, other than MBC, are collectively referred to herein as the “Grantors”). The Grantors are also required to pledge additional assets as collateral for the Senior Secured Credit Facilities as they and future guarantor subsidiaries acquire them. The Senior Secured Credit Facilities contain customary covenants applicable to the Authority and its restricted subsidiaries, including covenants governing: incurrence of indebtedness, incurrence of liens, payment of dividends and other distributions, investments, asset sales, affiliate transactions, mergers or consolidations and capital expenditures. Additionally, the Senior Secured Credit Facilities include financial maintenance covenants pertaining to total leverage, secured leverage and minimum fixed charge coverage. As of September 30, 2015, the Authority and the Tribe were in compliance with all respective covenant requirements under the Senior Secured Credit Facilities. The Authority continues to monitor revenues and manage expenses and enhance operating efficiencies to ensure continued compliance with its financial covenant requirements under the Senior Secured Credit Facilities. While the Authority anticipates that it will remain in compliance with all covenant requirements under its Senior Secured Credit Facilities for all periods prior to maturity, it may need to increase revenues or offset any future declines in revenues by implementing cost saving and other initiatives to ensure compliance with these financial covenant requirements. If the Authority is unable to satisfy its financial covenant requirements, it would need to obtain waivers or consents under the Senior Secured Credit Facilities; however, the Authority can provide no assurance that it would be able to obtain such waivers or consents. If the Authority is unable to obtain such waivers or consents, it would be in default under its Senior Secured Credit Facilities, which may result in cross-defaults under its other outstanding indebtedness and allow its lenders and creditors to exercise their rights and remedies as defined under their respective agreements, including their right to accelerate the repayment of the Authority’s outstanding indebtedness. If such acceleration were to occur, the Authority can provide no assurance that it would be able to obtain the financing necessary to repay such accelerated indebtedness. Senior Unsecured Notes 2013 9 3 In August 2013, the Authority issued $500.0 million Senior Unsecured Notes with fixed interest payable at a rate of 9.75% per annum The 2013 Senior Unsecured Notes mature on September 1, 2021.

On or after September 1, 2016, the Authority may redeem the 2013 Senior Unsecured Notes, in whole or in part, at specified redemption prices, together with accrued interest (and additional interest in the case of the Additional 2013 Senior Unsecured Notes, if any) to the date of redemption. If the Authority experiences specific kinds of change of control triggering events, the Authority must offer to repurchase the 2013 Senior Unsecured Notes at a price equal to 101% of the principal amount thereof, plus accrued interest (and additional interest in the case of the Additional 2013 Senior Unsecured Notes, if any) to the purchase date. In addition, if the Authority undertakes certain types of asset sales and does not use the related sale proceeds for specified purposes, the Authority may be required to offer to repurchase the 2013 Senior Unsecured Notes at a price equal to 100% of the principal amount, plus accrued interest (and additional interest in the case of the Additional 2013 Senior Unsecured Notes, if any).

The 2013 Senior Unsecured Notes are uncollateralized general obligations of the Authority and are effectively subordinated to all of the Authority’s and the Guarantors’ and future guarantor subsidiaries’ senior secured indebtedness, including the Senior Secured Credit Facilities, to the extent of the value of the collateral securing such indebtedness. The 2013 Senior Unsecured Notes are also effectively subordinated to any indebtedness and other liabilities (including trade payables) of the Authority’s subsidiaries that do not guarantee the 2013 Senior Unsecured Notes. The 2013 Senior Unsecured Notes rank equally in right of payment with the Authority’s other unsecured, unsubordinated indebtedness, including trade payables. The 2013 Senior Unsecured Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors. The 2013 Senior Unsecured Notes indenture contains certain covenants that, subject to certain significant exceptions, limit, among other things, the Authority’s and Guarantors’ ability to incur additional debt, pay dividends or distributions, make certain investments, create liens on assets, enter into transactions with affiliates, merge or consolidate with another company or transfer and sell assets. The 2013 Senior Unsecured Notes indenture includes customary events of default, including, but not limited to, failure to make required payments, failure to comply with certain agreements or covenants, failure to pay certain other indebtedness, the occurrence of which is caused by a failure to pay principal, premium or interest or results in the acceleration of such indebtedness, certain events of bankruptcy and insolvency and certain judgment defaults.

As part of the exchange offer, the Authority solicited and received consents from tendering holders to certain amendments to the indentures governing the 2005 Senior Subordinated Notes, which eliminated certain covenants under the notes and related indenture. The aggregate principal amount of 2005 Senior Subordinated Notes tendered and exchanged was $140.3 million. Subsequent to the Authority’s March 2012 private exchange offer, $9.7 million of the 2005 Senior Subordinated Notes remained outstanding, which amount, plus accrued interest, was repaid at maturity on February 15, 2015 with cash on hand and drawings under the Revolving Facility.

The 2012 Senior Subordinated Notes and guarantees have not been and will not be registered under the Securities Act of 1933 or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements. The 2012 Senior Subordinated Notes are uncollateralized general obligations of the Authority and are subordinated to borrowings under the Senior Secured Credit Facilities and 2013 Senior Unsecured Notes. The 2012 Senior Subordinated Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors. The 2012 Senior Subordinated Notes indenture contains certain non-financial and financial covenant requirements with which the Authority and the Tribe must comply. The non-financial covenant requirements include, among other things, reporting obligations, compliance with laws and regulations, maintenance of licenses and insurances and continued existence of the Authority. The financial covenant requirements include, among other things, subject to certain exceptions, limitations on the Authority’s and the Guarantors’ ability to incur additional indebtedness, pay dividends or distributions, make certain investments, create liens on assets, enter into transactions with affiliates, merge or consolidate with another company, transfer or sell assets or impair assets constituting collateral. As of September 30, 2015, the Authority and the Tribe were in compliance with all respective covenant requirements under the senior and senior subordinated note indentures. The Authority or its affiliates may, from time to time, seek to purchase or otherwise retire outstanding indebtedness for cash in open market purchases, privately negotiated transactions or otherwise. Any such transaction will depend on prevailing market conditions and the Authority’s liquidity and covenant requirement restrictions, among other factors. Line of Credit In November 2013, the Authority entered into a $16.5 million revolving credit facility with Bank of America, N.A. (the “Line of Credit”). The Line of Credit is coterminous with the Senior Secured Credit Facilities. Pursuant to provisions of the Senior Secured Credit Facilities, under certain circumstances, the Line of Credit may be converted into loans under the Senior Secured Credit Facilities. Under the Line of Credit, each advance accrues interest on the basis of a one-month LIBOR Rate plus an applicable margin based on the Authority’s total leverage ratio, as each term is defined under the Line of Credit. As of September 30, 2015, no amount was drawn on the Line of Credit. Borrowings under the Line of Credit are uncollateralized obligations. The Line of Credit contains negative covenants and financial maintenance covenants that are substantially the same as those contained in the Senior Secured Credit Facilities.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	NOTE 8—RELATED PARTY TRANSACTIONS: Distributions to the Tribe totaled $50.0 million for each of the fiscal years ended September 30, 2015, 2014 and 2013. The Tribe provides certain governmental and administrative services in connection with the operation of Mohegan Sun. The Authority incurred expenses for such services totaling $28.3 million, $27.1 million and $26.8 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. The Authority purchases most of its utilities, including electricity, gas, water and waste water services, from an instrumentality of the Tribe, the Mohegan Tribal Utility Authority. The Authority incurred costs for such utilities totaling $17.4 million, $19.3 million and $17.8 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. The Authority incurred interest expense associated with borrowings from the Mohegan Tribe totaling $2.1 million, $2.3 million and $3.0 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. The Authority leases the land on which Mohegan Sun is located from the Tribe under a long-term lease agreement. The agreement requires the Authority to make a nominal annual rental payment. This lease has an initial term of 25 years and is renewable for an additional 25-year term upon expiration. In February 2015, the Authority entered into a fourth amendment to the land lease pursuant to which it released from the land lease an approximately 1.2-acre site to be used by the Tribe to finance, develop and own, through MTFA, a 400-room hotel and related improvements. In connection with this transaction, effective March 5, 2015, the Authority entered into a sublease agreement with MTFA to sublease the site and the completed hotel and related improvements for the purpose of operating the hotel on a triple net basis for a term of 28 years and 4 months, commencing upon the completion of the project. Rental payments under the sublease agreement will also commence upon the completion of the project. Completion and opening of the project is anticipated to occur in the fall of 2016. The Authority classified the sublease as an operating lease for financial reporting purposes in accordance with authoritative guidance issued by the FASB pertaining to the accounting for leases. In addition, in July 2008, the Authority entered into a land lease agreement with the Tribe, replacing a prior land lease agreement, relating to property located adjacent to the Tribe’s reservation that is utilized by Mohegan Sun for employee parking. This agreement requires the Authority to make monthly payments equaling $75,000 until maturity on June 30, 2018. The Authority classified this lease as a capital lease for financial reporting purposes due to the existence of a bargain purchase option at the expiration of the lease. In September 1995, the Tribe adopted the Mohegan Tribal Employment Rights Ordinance, as amended from time to time (the “TERO”), which sets forth hiring and contracting preference requirements for employers and entities conducting business on Tribal lands on or adjacent to the Mohegan Reservation. Pursuant to the TERO, the Authority and other covered employers are required to give hiring, promotion, training, retention and other employment-related preferences to Native Americans who meet the minimum qualifications for the applicable employment position. However, this preference requirement does not apply to key employees as such persons are defined under the TERO. Similarly, any entity awarding a contract or subcontract valued up to $250,000 to be performed on Tribal lands must give preference, first, to certified Mohegan entities submitting commercially responsible bids, and second, to other certified Native American entities. This contracting preference is conditioned upon the bid by the preferred certified entity being within 5% of the lowest bid by a non-certified entity. Contracts in excess of $250,000 are awarded to the lowest commercially responsible bidder, on a competitive basis, with preference to certified Mohegan entities and then other certified Native American entities in the event of a matching bid. In addition, for contracts valued at any amount, other than those with federal or other special financing, a certified Mohegan entity which submits a bid that is not more than 10% higher than the lowest bid shall be awarded the contract for work to be performed on Tribal lands, if the certified Mohegan entity accepts the bid at the amount proffered by the lowest bidder and meets all other requirements. The TERO establishes procedures and requirements for certifying Mohegan entities and other Native American entities. Certification is based largely on the level of ownership and control exercised by the members of the Tribe or other Native American tribes, as the case may be, over the entity bidding on a contract. As of September 30, 2015, the Authority employed approximately 115 members of the Tribe.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 10—COMMITMENTS AND CONTINGENCIES: Slot Win and Free Promotional Slot Play Contributions In May 1994, the Tribe and the State of Connecticut entered into a Memorandum of Understanding (“MOU”), which sets forth certain matters regarding implementation of the Mohegan Compact. The MOU stipulates that a portion of revenues from slot machines must be paid to the State of Connecticut (“Slot Win Contribution”). Slot Win Contribution payments are not required if the State of Connecticut legalizes any other gaming operation with slot machines, video facsimiles of games of chance or other commercial casino games within the State of Connecticut, except those consented to by the Tribe and the MPT. For each 12-month period commencing July 1, 1995, Slot Win Contribution payments shall be the lesser of: (1) 30% of gross revenues from slot machines or (2) the greater of (a) 25% of gross revenues from slot machines or (b) $80.0 million. In September 2009, the Authority entered into a settlement agreement with the State of Connecticut regarding contribution payments on the Authority’s free promotional slot play program. Under the terms of the settlement agreement, effective July 1, 2009, the State of Connecticut agreed that no value shall be attributed to free promotional slot plays utilized by patrons at Mohegan Sun for purposes of calculating monthly contribution payments, provided that the aggregate amount of free promotional slot plays during any month does not exceed a certain threshold of gross revenues from slot machines for such month. In the event free promotional slot plays granted by the Authority exceed such threshold, contribution payments are required on such excess face amount of free promotional slot plays at the same rate as Slot Win Contribution payments, or 25%. The threshold before contribution payments on free promotional slot plays are required is currently 11% of gross revenues from slot machines. The Authority reflected expenses associated with the combined Slot Win Contribution and free promotional slot play contribution totaling $145.6 million, $146.5 million and $155.8 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively.

The Pennsylvania Race Horse Development and Gaming Act stipulates that holders of Category One slot machine licenses must pay a portion of revenues from slot machines to the PGCB on a daily basis (“Pennsylvania Slot Machine Tax”), which includes local share assessments to be paid to the cities and municipalities hosting Mohegan Sun Pocono and amounts to be paid to the Pennsylvania Harness Horsemen’s Association, Inc. (the “PHHA”). The Pennsylvania Slot Machine Tax is currently 55% of gross revenues from slot machines, 2% of which is subject to a $10.0 million minimum annual threshold to ensure that the host cities and municipalities receive an annual minimum of $10.0 million in local share assessments. Downs Racing maintains a $1.5 million escrow deposit in the name of the Commonwealth of Pennsylvania for Pennsylvania Slot Machine Tax payments, which was included in other assets, net, in the accompanying consolidated balance sheets.

The Authority reflected expenses associated with the Pennsylvania Regulatory Fee totaling $4.6 million, $4.7 million and $4.2 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. As of September 30, 2015 and 2014, outstanding Pennsylvania Regulatory Fee payments to the PGCB totaled $70,000 and $147,000, respectively. Pennsylvania Gaming Control Board Loans The PGCB was initially granted $36.1 million in loans to fund start-up costs for gaming in the Commonwealth of Pennsylvania, which are to be repaid by slot machine licensees (the “Initial Loans”). The PGCB was subsequently granted an additional $63.8 million in loans to fund ongoing gaming oversight costs, which are also to be repaid by slot machine licensees (the “Subsequent Loans”). Repayment of the Initial Loans will commence when all 14 authorized gaming facilities are opened in the Commonwealth of Pennsylvania. Currently, 12 of the 14 authorized gaming facilities have commenced operations. As of September 30, 2015, the Authority has concluded that a repayment contingency for the Initial Loans is probable but not reasonably estimable since the PGCB has not yet established a method of assessment of repayment for the Initial Loans and, as such, the Authority has not recorded a related accrual for such repayment. In June 2011, the PGCB adopted a method of assessment of repayment for the Subsequent Loans pursuant to which repayment commenced on January 1, 2012 and will continue over a 10-year period in accordance with a formula based on a combination of a single fiscal year and cumulative gross revenues from slot machines for each operating slot machine licensee. The Authority reflected expenses associated with this repayment schedule totaling $620,000, $638,000 and $633,000 for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. Horsemen’s Agreement Downs Racing and the PHHA are parties to an agreement that governs all live harness racing and simulcasting and account wagering at the Pennsylvania Facilities through December 31, 2015. As of September 30, 2015 and 2014, outstanding payments to the PHHA for purses earned by horsemen, but not yet paid, and other fees totaled $7.4 million and $8.1 million, respectively. Priority Distribution Agreement In August 2001, the Authority and the Tribe entered into an agreement (the “Priority Distribution Agreement”), which stipulates that the Authority must make monthly payments to the Tribe to the extent of the Authority’s Net Cash Flow as defined under the Priority Distribution Agreement. The Priority Distribution Agreement was amended as of December 31, 2014. As amended, the Priority Distribution Agreement, which has a perpetual term, limits the minimum aggregate priority distribution payments in each calendar year to $40.0 million. Payments under the Priority Distribution Agreement: (1) do not reduce the Authority’s obligations to reimburse the Tribe for governmental and administrative services provided by the Tribe or to make payments under any other agreements with the Tribe, (2) are limited obligations of the Authority and are payable only to the extent of the Authority’s Net Cash Flow as defined under the Priority Distribution Agreement and (3) are not secured by a lien or encumbrance on any of the Authority’s assets or properties. The Authority reflected payments associated with the Priority Distribution Agreement totaling $31.5 million, $19.5 million and $19.2 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. Town of Montville Agreement In June 1994, the Tribe entered into an agreement with the Town of Montville (the “Town”) under which the Tribe agreed to pay the Town $500,000 annually to minimize the impact of the Tribe’s reservation being held in trust on the Town. The Tribe has assigned its rights and obligations under this agreement to the Authority. Land Lease Agreement The land upon which Mohegan Sun is located is held in trust for the Tribe by the United States. The Authority entered into a land lease agreement with the Tribe to lease the property and improvements and related facilities constructed or installed on the property. In March 2007, the agreement was amended to update the legal description of the property, and, in April 2007, the amended agreement was approved by the Secretary of the Interior. In February 2015, the agreement was again amended to update the legal description of the property, which amendment was approved by the Secretary of the Interior in March 2015. The following summarizes the key provisions of the land lease agreement: Term The term of the agreement is 25 years with an option, exercisable by the Authority, to extend the term for one additional 25-year period. Upon termination of the agreement, the Authority will be required to surrender to the Tribe possession of the property and improvements, excluding any equipment, furniture, fixtures or other personal property. Rent and Other Operating Costs and Expenses The agreement requires the Authority to pay the Tribe a nominal annual rental fee. For any period that the Tribe or another agency or instrumentality of the Tribe is not the tenant, the rent will be 8% of such tenant’s gross revenues from the property. The Authority is responsible for all costs and expenses of owning, operating, constructing, maintaining, repairing, replacing and insuring the property. Use of Property The Authority may utilize the property and improvements solely for the operation of Mohegan Sun, unless prior approval is obtained from the Tribe for any proposed alternative use. The Authority may not construct or alter any building or improvement located on the property unless complete and final plans and specifications are approved by the Tribe. Following foreclosure of any mortgage on the Authority’s interest under the agreement or any transfer of such interest to the holder of such mortgage in lieu of foreclosure, the property and improvements may be utilized for any lawful purpose, subject to applicable codes and governmental regulations; provided, however, that a non-Indian holder of the property may under no circumstance conduct gaming operations on the property. Permitted Mortgages and Rights of Permitted Mortgagees The Authority may not mortgage, pledge or otherwise encumber its leasehold estate in the property except to a holder of a permitted mortgage. Under the terms of the agreement, permitted mortgages include the leasehold mortgage securing the Authority’s senior secured indebtedness, provided that, among other things: (1) the Tribe will have the right to notice of, and to cure, any default of the Authority, (2) the Tribe will have the right to prior notice of an intention by the holder to foreclose on the permitted mortgage and the right to purchase the mortgage in lieu of any foreclosure and (3) the permitted mortgage is subject and subordinated to any and all access and utility easements granted by the Tribe under the agreement. Under the terms of the agreement, each holder of a permitted mortgage has the right to notice of any default of the Authority under the agreement and the opportunity to cure such default within the applicable cure period. Default Remedies The Authority will be in default under the agreement if, subject to the notice provisions, it fails to make lease payments or comply with covenants under the agreement or if it pledges, encumbers or conveys its interest in violation of the terms of the agreement. Following a default, the Tribe may, with approval from the Secretary of the Interior, terminate the agreement unless a permitted mortgage remains outstanding with respect to the property. In such case, the Tribe may not: (1) terminate the agreement or the Authority’s right to possession of the property, (2) exercise any right of re-entry, (3) take possession of and/or relet the property or any portion thereof or (4) enforce any other right or remedy, which may materially and adversely affect the rights of the holder of the permitted mortgage, unless the default triggering such rights was a monetary default of which such holder failed to cure after notice. Litigation The Authority is a defendant in various litigation matters resulting from its normal course of business. In management’s opinion, the aggregate liability, if any, arising from such litigations will not have a material impact on the Authority’s financial position, results of operations or cash flows.

RELINQUISHMENT AGREEMENT	NOTE 11—RELINQUISHMENT AGREEMENT: In February 1998, the Authority and TCA entered into a relinquishment agreement (the “Relinquishment Agreement”). Effective January 1, 2000, the Relinquishment Agreement superseded a then-existing management agreement with TCA requiring, among other things, that the Authority make certain payments to TCA out of, and determined as a percentage of, Revenues, as defined under the Relinquishment Agreement, generated by Mohegan Sun over a 15-year period. The Authority, in accordance with authoritative guidance issued by the FASB pertaining to the accounting for contingencies, recorded a $549.1 million relinquishment liability at September 30, 1998 based on the estimated present value of its obligations under the Relinquishment Agreement. The Relinquishment Agreement expired on December 31, 2014. As of September 30, 2015, no amount was outstanding under the Relinquishment Agreement. As of September 30, 2014, the carrying amount of the relinquishment liability was $25.2 million. The decrease in the relinquishment liability during the fiscal year ended September 30, 2015 was due to $25.2 million in relinquishment payments and a $243,000 relinquishment liability reassessment credit. This reduction in the relinquishment liability was offset by $227,000 representing the accretion of discount to the relinquishment liability. Relinquishment payments consisted of the following (in millions): For the Fiscal Years Ended September 30, 2015 September 30, 2014 September 30, 2013 Principal $ 24.4 $ 46.6 $ 45.4 Accretion of discount 0.8 2.9 5.8 Total $ 25.2 $ 49.5 $ 51.2 The accretion of discount to the relinquishment liability reflects the accretion of the discount to the present value of the relinquishment liability for the impact of the time value of money. As of September 30, 2015, no relinquishment payment was earned but unpaid. As of September 30, 2014, relinquishment payments earned but unpaid were $13.2 million. The relinquishment liability reassessment credits of $243,000, $1.9 million and $249,000 for the fiscal years ended September 30, 2015, 2014 and 2013, respectively, resulted from reductions in Mohegan Sun revenues and revenue projections as of the end of each respective fiscal year compared to projections as of the end of the related prior fiscal year.

Cowlitz Project
MOHEGAN VENTURES WISCONSIN, LLC (MENOMINEE PROJECT)	NOTE 12—MOHEGAN VENTURES-NORTHWEST, LLC (COWLITZ PROJECT): In July 2004, the Authority formed Mohegan Ventures-NW as its wholly-owned subsidiary. Mohegan Ventures-NW is one of three current members in Salishan-Mohegan, which was formed to participate in the Cowlitz Project, a proposed casino to be owned by the Cowlitz Tribe and to be located on the Cowlitz reservation in Clark County, Washington. Mohegan Ventures-NW, Salishan Company, LLC, an unrelated entity, and a subsidiary of the Tribe hold membership interests in Salishan-Mohegan of 49.15%, 40% and 10.85%, respectively. Salishan-Mohegan holds a 100% membership interest in Salishan-Mohegan Two and Interchange Development Group, both of which were formed to acquire certain property related to the Cowlitz Project. Salishan-Mohegan is not a restricted entity of the Authority, and therefore, is not a guarantor of the Authority’s debt obligations. In September 2004, Salishan-Mohegan entered into development and management agreements with the Cowlitz Tribe in connection with the Cowlitz Project, which agreements have been amended from time to time. Under the terms of the development agreement, Salishan-Mohegan assists in securing financing, as well as administration and oversight of the planning, designing, development, construction and furnishing of the proposed casino. The development agreement provides for development fees of 3% of total project costs, as defined under the development agreement. Under the terms of Salishan-Mohegan’s operating agreement, development fees will be distributed to Mohegan Ventures-NW. In 2006, pursuant to the development agreement, Salishan-Mohegan purchased an approximately 152-acre site for the proposed casino. Under the terms of the management agreement, Salishan-Mohegan will manage, operate and maintain the proposed casino for a period of seven years following its opening. The management agreement provides for management fees of 24% of net revenues, as defined under the management agreement, which approximates net income earned from the Cowlitz Project. Under the terms of Salishan-Mohegan’s operating agreement, management fees will be allocated to the members of Salishan-Mohegan based on their respective membership interests. The management agreement is subject to approval by the National Indian Gaming Commission (the “NIGC”). In August 2014, the Cowlitz Tribe’s Class III Tribal-State gaming compact with the State of Washington became effective with notice of federal approval published in the Federal Register. According to the notice, the compact allows for two gaming facilities, allocates 975 gaming machines for leasing, authorizes the operation of up to 3,000 gaming machines and 125 table games, and is in effect until terminated by written agreement of both parties. Under the terms of the development agreement, certain receivables contributed to Salishan-Mohegan and amounts advanced by Salishan-Mohegan on behalf of the Cowlitz Tribe are reimbursable to Salishan-Mohegan by the Cowlitz Tribe, subject to appropriate approvals defined under the development agreement. As of September 30, 2015, reimbursements are contingent and are to be distributed upon: (1) the related property being taken into trust by the United States Department of the Interior and (2) the receipt of necessary financing for the development of the proposed casino. As of September 30, 2015, the Authority accrued interest on the Salishan-Mohegan receivables at an annual rate of 10.0%. In March 2013, two lawsuits challenging a December 2010 decision of the Assistant Secretary—Indian Affairs of the Department of the Interior to take the Cowlitz Project site into trust were dismissed on procedural grounds. In April 2013, pursuant to judicial directive, the Department of the Interior issued a new Record of Decision to take the Cowlitz Project site into trust, determining for a second time that the site will serve as the initial reservation of the Cowlitz Tribe and that the tribe may conduct gaming on such lands under the Indian Gaming Regulatory Act. In June 2013, the plaintiffs in the earlier litigation filed two new lawsuits challenging the new Record of Decision, and, in July 2013, those lawsuits were consolidated. By Notice of Trust Acquisition filed with the court in October 2014, while motions for summary judgment filed by the plaintiffs and the defendants were pending, the defendants provided the court notice of the United States Department of the Interior’s planned trust acquisition of the Cowlitz Project site, which was the subject of the litigation, on the earlier of: (1) January 21, 2015 and (2) 30 days after a court order granting summary judgment in favor of the defendants. On December 12, 2014, a U.S. District Court for the District of Columbia judge entered an order granting summary judgment in favor of the defendants, thereby upholding the Record of Decision and denying the plaintiffs’ motion. The plaintiffs subsequently appealed and such appeals remain pending before the Court of Appeals for the District of Columbia Circuit. The Authority can provide no assurance as to the outcome of these appeals or any future litigation. In March 2015, the Cowlitz Project site was taken into trust by the United States Department of the Interior for the benefit of the Cowlitz Tribe. In connection with this event, the Cowlitz Tribe leased a substantial portion of the Cowlitz Project site back to Salishan-Mohegan for a nominal rental fee. The carrying value of the land totaling approximately $20.0 million, which was included in property and equipment, net, in the accompanying consolidated balance sheet as of September 30, 2014, was transferred to the Cowlitz Tribe at the time the site was taken into trust. This transfer resulted in an additional long-term receivable due from the Cowlitz Tribe as permitted under the development agreement, and was included in receivables, net, and other assets, net, in the accompanying consolidated balance sheet as of September 30, 2015. Construction of the Cowlitz Project commenced on September 18, 2015. The Authority can provide no assurance that remaining permits or approvals related to construction and opening or other remaining steps and conditions for the Cowlitz Project site to be approved for gaming will be satisfied. Furthermore, the Authority can provide no assurance as to the outcome of the pending federal court appeal or any future litigation relating to the Cowlitz Project. In light of the aforementioned and the uncertainty in the development of the Cowlitz Project, the Authority maintains a reserve for doubtful collection of the Salishan-Mohegan receivables, which is based on the Authority’s estimate of the probability that the receivables will be collected. As of September 30, 2015 and 2014, the Salishan-Mohegan receivables, including accrued interest, totaled $90.7 million and $56.8 million, respectively. As of September 30, 2015 and 2014, related reserves for doubtful collection totaled $21.2 million and $17.0 million, respectively. The Salishan-Mohegan receivables were included in other assets, net, in the accompanying consolidated balance sheets. On December 4, 2015, the Cowlitz Tribal Gaming Authority (the “CTGA”) closed on its financing for the Cowlitz Project. The financing provides funding for construction of the Cowlitz Project and a partial repayment of the Salishan-Mohegan receivables. In connection with this transaction, Salishan-Mohegan was repaid $19.4 million of the Salishan-Mohegan receivables, a portion of which was used to repay certain outstanding debt of Salishan-Mohegan. In accordance with the terms of the development agreement, as amended, the remaining outstanding Salishan-Mohegan receivables are to be repaid in equal monthly installments over a seven-year period beginning in the first month following the opening of the Cowlitz Project, plus accrued interest at a rate equal to 1.0% above the Cowlitz Project financing rate, or 12.5%. Pursuant to the development agreement, repayment of the Salishan-Mohegan receivables may accelerate depending on the level of available cash at the end of each fiscal year, subject to certain conditions as set forth in the development agreement, including conditions of the Cowlitz financing. Also in connection with the Cowlitz financing, Salishan-Mohegan assigned the lease for the Cowlitz Project site to CTGA.
Menominee Project
MOHEGAN VENTURES WISCONSIN, LLC (MENOMINEE PROJECT)	NOTE 13—MOHEGAN VENTURES WISCONSIN, LLC (MENOMINEE PROJECT): In March 2007, the Authority formed MVW as its wholly-owned subsidiary and one of two original members in WTG, which was formed to participate in the Menominee Project, a proposed casino to be owned by the Menominee Tribe and to be located in Kenosha, Wisconsin. MVW now holds 100% membership interest in WTG. MVW and WTG are full and unconditional guarantors of the Authority’s outstanding indebtedness. In connection with the Menominee Project, the Authority entered into a management agreement with the Menominee Tribe and the Menominee Kenosha Gaming Authority (the “MKGA”), and WTG purchased the development rights for the Menominee Project under a development agreement with the Menominee Tribe and the MKGA. In September 2010, WTG entered into a release and reimbursement agreement pursuant to which WTG: (1) relinquished its development rights and was relieved of its development obligations for the Menominee Project, (2) retained its rights to reimbursement of certain receivables related to reimbursable costs and expenses advanced by WTG on behalf of the Menominee Tribe for the Menominee Project, subject to certain conditions and (3) assigned the option to purchase the proposed Menominee Project site in Kenosha to MKGA. The Authority retained its interest in the management agreement. Due to the uncertainty in the development of the Menominee Project, as of September 30, 2008, the Authority fully reserved for these receivables and wrote-off the related development rights intangible asset. In February 2012, the MKGA terminated its efforts to seek NIGC approval of the management agreement. As of September 30, 2015, the WTG receivables remain fully reserved.

INVESTMENT IN WNBA FRANCHISE	NOTE 14—INVESTMENT IN WNBA FRANCHISE: In January 2003, the Authority formed MBC as its wholly-owned subsidiary to own and operate a professional basketball team in the WNBA. In January 2003, the Authority and MBC entered into a membership agreement with WNBA, LLC which sets forth the terms and conditions under which MBC acquired its membership in the WNBA and the right to own and operate a team. The Authority guaranteed the obligations of MBC under the membership agreement. MBC is a full and unconditional guarantor of the Authority’s outstanding indebtedness. In connection with MBC’s acquisition of its membership in the WNBA and the right to own and operate a team, the Authority estimated the fair value of the initial player roster to be $4.8 million and the remaining $5.5 million of MBC’s aggregate investment was recognized as a franchise value. The player roster value was amortized over seven years and became fully amortized in fiscal 2010. The franchise value is being amortized over thirty years and is assessed for impairment whenever events or changes in circumstances indicate that its carrying amount may not be recoverable. As of September 30, 2015 and 2014, accumulated amortization on the franchise value was $2.3 million and $2.1 million, respectively. Amortization expense associated with the franchise value totaled $183,000 for each of the fiscal years ended September 30, 2015, 2014 and 2013. The Authority expects to incur amortization expenses related to the franchise value of $183,000 for each of the next five fiscal years. The franchise value was included in intangible assets, net, in the accompanying consolidated balance sheets. MBC currently owns approximately 4.2% of the membership interest in WNBA, LLC which is accounted for under the cost method. Under the terms of the Limited Liability Company Agreement of WNBA, LLC, if at any time, WNBA, LLC’s Board of Governors determines that additional funds are needed for WNBA, LLC’s or any league entity’s general business, the Board of Governors may require additional cash capital contributions. In such event, each member shall be obligated to contribute to WNBA, LLC an amount of cash equal to that member’s proportionate share of ownership. No such cash capital contribution has been required by WNBA, LLC through September 30, 2015.

Segment Reporting [Abstract]
SEGMENT REPORTING	NOTE 15—SEGMENT REPORTING: As of September 30, 2015, the Authority owns and operates, either directly or through wholly-owned subsidiaries, Mohegan Sun, the Connecticut Sun franchise and the Mohegan Sun Golf Club, and has partnered with an unrelated third-party to own and operate the New England Black Wolves franchise (collectively, the “Connecticut Facilities”), and the Pennsylvania Facilities. Substantially all of the Authority’s revenues are derived from these operations. The Connecticut Sun franchise, the Mohegan Sun Golf Club and the New England Black Wolves franchise are aggregated with the Mohegan Sun operating segment because these operations all share similar economic characteristics, which is to generate gaming and entertainment revenues by attracting patrons to Mohegan Sun. The Authority’s executive officers review and assess the performance and operating results and determine the proper allocation of resources to the Connecticut Facilities and the Pennsylvania Facilities on a separate basis. Accordingly, the Authority has two separate reportable segments: (1) Mohegan Sun, which includes the operations of the Connecticut Facilities and (2) Mohegan Sun Pocono, which includes the operations of the Pennsylvania Facilities. The Authority’s operations related to investments in unconsolidated affiliates and certain other Corporate and management operations 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.

SUBSEQUENT EVENTS

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	NOTE 17—SUBSEQUENT EVENTS: Facility Agreement On November 18, 2015, the Authority entered into an agreement (the “Facility Agreement”) by and among the Authority, the Tribe and UBS AG, London Branch (“UBS”). Pursuant to the Facility Agreement, the Authority may issue, from time to time, to UBS or its designee, senior unsecured notes in an aggregate principal amount of up to $200.0 million, with varying amounts, borrowing dates, maturities and interest rates, as may be agreed with UBS or its designee. On November 20, 2015, pursuant to the Facility Agreement, the Authority entered into a note purchase agreement (the “Note Purchase Agreement”) by and among the Authority, the Tribe and the purchaser named therein (the “Purchaser”). In accordance with the Note Purchase Agreement, the Authority issued floating rate senior notes due 2017 in an aggregate principal amount of $100.0 million (the “Notes”) to the Purchaser in a private offering that closed on November 20, 2015. The Notes are senior unsecured obligations of the Authority. Pursuant to a guarantee agreement dated November 20, 2015, certain of the Authority’s subsidiaries, which are the same Guarantors that guarantee the Authority’s Senior Secured Credit Facilities and senior unsecured and senior subordinated notes, have guaranteed the Notes. The Notes bear interest at a rate per annum equal to LIBOR plus 4.45%, payable quarterly. The Notes mature on December 15, 2017. The Authority used the net proceeds from the Notes to refinance existing indebtedness and to finance new development opportunities. The Authority may redeem the Notes at any time, in whole or in part, at a price equal to 100% of the principal amount of the Notes redeemed plus accrued interest to the date of redemption, customary breakage costs, a “make-whole amount,” and, if redeemed within one year of the date of issuance, a premium of 0.25%. If the Authority experiences specific kinds of change of control events, undertakes certain types of asset sales or experiences certain swap-related credit determinations, it will be required to make an offer to purchase the Notes at the purchase prices set forth in the Note Purchase Agreement. In addition, if any gaming regulatory authority requires a holder of the Notes to be licensed, qualified or found suitable under applicable gaming laws, and such holder does not obtain such license, qualification or finding of suitability within a specified time, the Authority can call for redemption of the Notes held by such holder. The Notes and guarantees have not been and will not be registered under the Securities Act of 1933 or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from such registration requirements. The Notes are uncollateralized general obligations of the Authority and are effectively subordinated to all of the Authority’s and the Guarantors’ and future guarantor subsidiaries’ senior secured indebtedness, including the Senior Secured Credit Facilities, to the extent of the value of the collateral securing such indebtedness. The Notes are also effectively subordinated to any indebtedness and other liabilities (including trade payables) of the Authority’s subsidiaries that do not guarantee the Notes. The Notes rank equally in right of payment with the Authority’s other unsecured, unsubordinated indebtedness, including trade payables. The Notes are fully and unconditionally guaranteed, jointly and severally, by the Guarantors. The Note Purchase Agreement contains certain covenants that, subject to certain significant exceptions, limit, among other things, the Authority’s and the Guarantors’ ability to incur additional debt, pay dividends or distributions, make certain investments, create liens on assets, enter into transactions with affiliates, merge or consolidate with another company or transfer and sell assets. The Note Purchase Agreement includes customary events of default, including, but not limited to, failure to make required payments, failure to comply with certain agreements or covenants, certain cross-defaults, certain events of bankruptcy and insolvency and certain judgment defaults. 2015 Mohegan Tribe Promissory Note On November 16, 2015, the Tribe made a $22.5 million loan to Mohegan Gaming Advisors (the “2015 Mohegan Tribe Promissory Note”). The 2015 Mohegan Tribe Promissory Note matures on April 15, 2016. The 2015 Mohegan Tribe Promissory Note accrues interest at an annual rate of 5.0% and requires a principal payment of $8.5 million, plus accrued interest, on January 15, 2016, with the remaining principal amount, plus accrued interest, due at maturity. New Downs Lodging Credit Facility On November 25, 2015, Downs Lodging repaid and terminated the Downs Lodging Credit Facility with proceeds from a new credit agreement providing for a $25.0 million term loan from a third-party lender (the “New Downs Lodging Credit Facility”) and a cash payment of the remaining principal amount outstanding under the Downs Lodging Credit Facility, plus accrued interest and fees. The New Downs Lodging Credit Facility matures on November 24, 2019, subject to earlier maturity in the event that 5.0% or more of the Authority’s total funded indebtedness matures prior to that date, in which case the New Downs Lodging Credit Facility matures six months prior to such date. Principal outstanding under the New Downs Lodging Credit Facility amortizes in equal monthly amounts of approximately $260,000 commencing January 1, 2016, with the remaining balance due at maturity. The New Downs Lodging Credit Facility accrues interest as follows: (i) for base rate loans, at a base rate equal to the greater of (a) the prime rate and (b) the federal funds rate plus 50 basis points (the greater of (a) and (b), the “base rate”), plus 250 basis points and (ii) for Eurodollar rate loans, at the applicable LIBOR rate plus 350 basis points. Interest on base rate loans is payable monthly. Interest on Eurodollar rate loans is payable at the end of each applicable interest period. The New Downs Lodging Credit Facility is a senior secured obligation of Downs Lodging, collateralized by all existing and future assets of Downs Lodging. The New Downs Lodging Credit Facility subjects Downs Lodging to certain covenant requirements customarily found in loan agreements for similar transactions. Additionally, the New Downs Lodging Credit Facility includes a financial maintenance covenant pertaining to minimum debt service coverage.

BASIS OF PRESENTATION AND SUM24

BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Sep. 30, 2015
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Authority and its majority and wholly-owned subsidiaries and entities. In accordance with authoritative guidance issued by the Financial Accounting Standards Board (the “FASB”) pertaining to consolidation of variable interest entities, the accounts of Salishan-Mohegan are consolidated into the accounts of Mohegan Ventures-NW and the accounts of NEBW are consolidated into the accounts of Mohegan Lacrosse as Mohegan Ventures-NW and Mohegan Lacrosse are deemed to be the primary beneficiaries. In consolidation, all inter-company balances and transactions were eliminated.
Change in Accounting Principles	Change in Accounting Principles In April 2015, the FASB issued an accounting standard update to clarify the required presentation of debt issuance costs. The update requires that debt issuance costs related to non-revolving debt be presented in the balance sheet as a reduction to the carrying amount of the related debt rather than as an asset. This guidance is required to be applied on a retrospective basis and is effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority early adopted this guidance in the accompanying consolidated financial statements. The effect of adopting this guidance to the accompanying consolidated balance sheet as of September 30, 2014 was a $20.4 million decrease in other assets, net and long-term debt, net of current portion. The accompanying supplemental condensed consolidating financial statements within Note 16 also have been revised to reflect this adjustment.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires the Authority to make estimates and judgments that affect the reported amounts of assets and liabilities, revenues and expenses and related disclosures of contingent assets and liabilities. The most significant estimates included in the accompanying consolidated financial statements relate to reserves for doubtful accounts, asset valuation, the liabilities associated with self-insurance and unredeemed Momentum Dollars, contingencies and litigation. Actual results could differ from these estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of deposits that can be redeemed on demand and investments with original maturities of less than 90 days. Cash equivalents are carried at cost, which approximates market value. Cash and cash equivalents include all operating cash and in-house funds
Restricted Cash	Restricted Cash Restricted cash consists of deposits that are contractually restricted as to their withdrawal or use. Restricted cash primarily includes cash held by Downs Racing pursuant to the Pennsylvania Race Horse Development and Gaming Act and Pennsylvania state statutes. The Pennsylvania Race Horse Development and Gaming Act requires Downs Racing to deposit a percentage of gross revenues from slot machines into a separate interest bearing account for the benefit of horsemen and breeders. In addition, Pennsylvania state statutes require Downs Racing to deposit net amounts received from the sale of lottery tickets into a separate designated account.
Accounts Receivable	Accounts Receivable Accounts receivable consists primarily of casino receivables, which represent credit extended to approved casino patrons, and hotel and other non-gaming receivables. The Authority maintains a reserve for doubtful collection, which is based on the Authority’s estimate of the probability that these receivables will be collected. The Authority assesses the adequacy of this reserve by continuously evaluating historical experience, creditworthiness of the related patron and all other available information. Future business or economic trends could affect the collectability of these receivables and the related reserve.
Long-Term Receivables	Long-Term Receivables Long-term receivables consist primarily of receivables from affiliates and others. Receivables from affiliates, which are included in receivables, net, and other assets, net, in the accompanying consolidated balance sheets, consist of reimbursable costs and expenses advanced by Salishan-Mohegan on behalf of the Cowlitz Tribe for the Cowlitz Project (refer to Note 12) and WTG on behalf of the Menominee Tribe for the Menominee Project (refer to Note 13). As of September 30, 2015, the Salishan-Mohegan receivables are payable upon: (1) the related property being taken into trust by the United States Department of the Interior and (2) the receipt of necessary financing for the development of the proposed casino. Due to the uncertainty in the development of the Cowlitz Project, the Authority maintains a reserve for doubtful collection of the Salishan-Mohegan receivables, which is based on the Authority’s estimate of the probability that the receivables will be collected. The Authority assesses the reserve for doubtful collection of the Salishan-Mohegan receivables for adequacy on a quarterly basis. Future developments in the construction and opening of the proposed casino or other matters affecting the Cowlitz Project could affect the collectability of the Salishan-Mohegan receivables and the related reserve. The WTG receivables are fully reserved. The WTG receivables are payable upon the receipt of necessary financing for the development of the proposed casino, subject to certain conditions. Receivables from others, which are primarily included in other assets, net, in the accompanying consolidated balance sheets, consist primarily of funds loaned to third-parties in connection with various diversification projects. Receivables from others also include a loan to a tenant at Mohegan Sun. The Authority maintains a reserve for doubtful collection of receivables from others, which is based on the Authority’s estimate of the probability that these receivables will be collected considering historical experience, creditworthiness of the related third-parties and tenant and all other available information.
Inventories	Inventories Inventories are stated at the lower of cost or market value and consist primarily of food and beverage, retail, hotel and operating supplies. Cost is determined using the average cost method. The Authority reduces the carrying value of slow-moving inventory to net realizable value, based on the Authority’s estimate of the amount of inventory that may not be utilized in future operations. Future business trends could affect the timely use of inventories.
Property and Equipment and Capitalized Interest	Property and Equipment Property and equipment are stated at cost. Depreciation is recognized over the estimated useful lives of the assets, other than land, on a straight-line basis. Leasehold improvements are amortized over the shorter of the lease terms or the estimated useful lives of the improvements. Estimated useful lives by asset categories are as follows: Buildings and land improvements 40 years Furniture and equipment 3 - 7 years The costs of significant improvements are capitalized. Costs of normal repairs and maintenance are expensed as incurred. Gains or losses on disposition of property and equipment are reflected in the accompanying consolidated financial statements. Property and equipment are assessed for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. If it is determined that the carrying amounts may not be recoverable based on current and future levels of income and cash flows, as well as other factors, an impairment loss will be recognized at such time. During its fourth quarter ended September 30, 2014, the Authority further re-evaluated its plans with respect to the development of the new hotel element of its suspended Project Horizon expansion, which included a hotel to be developed and owned by an instrumentality of the Tribe, as well as a third-party developed and owned retail center, and, based on new design plans, including the final location of the planned hotel, determined that certain design and earthwork related assets did not have any future benefit to the Authority. Accordingly, the Authority recognized a related $5.0 million impairment charge, which was recorded in the accompanying consolidated statement of loss for the fiscal year ended September 30, 2014. In March 2015, the Mohegan Tribal Finance Authority (“MTFA”), a wholly-owned instrumentality of the Tribe, agreed to develop the planned hotel. Concurrent with this transaction, the Authority re-evaluated the planned third-party developed and owned retail center, including master planning costs, and determined that these elements of the project were no longer feasible. Accordingly, the related assets did not have any future benefit to the Authority, and, during its second quarter ended March 31, 2015, the Authority recognized a related $2.5 million impairment charge, which was recorded in the accompanying consolidated statement of income for the fiscal year ended September 30, 2015. There are no assets remaining related to the suspended elements of Project Horizon (refer to Note 4). As of September 30, 2015 and 2014, the Authority assessed its property and equipment for any additional impairment and determined that no additional impairment existed. Capitalized Interest Interest costs incurred in connection with major development and construction projects are capitalized and included in the cost of the related project. Under instances where no debt is directly incurred in connection with a project, interest is capitalized on amounts expended on the project utilizing the weighted-average interest cost of the Authority’s outstanding borrowings. Capitalization of interest ceases when a project is substantially completed or development activity is suspended for an extended period of time.
Goodwill	Goodwill In accordance with authoritative guidance issued by the FASB pertaining to goodwill, the goodwill associated with the acquisition of the Pennsylvania Facilities is not subject to amortization, but is assessed at least annually for impairment by comparing its fair value to its carrying value. The fair value is determined utilizing an income approach based on projected discounted cash flows from the Pennsylvania Facilities, exclusive of capital expenditures requirements. If the carrying value of the goodwill exceeds its fair value, an impairment loss will be recognized to the extent that the carrying value of the goodwill exceeds its implied fair value. The income approach requires the Authority to make assumptions regarding future revenues and expenses, discount rates and the terminal value based on a market multiple of the Pennsylvania Facilities. As of September 30, 2015 and 2014, the Authority assessed the goodwill for impairment and determined that no impairment existed. If any of the following occurs, the goodwill may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from the Pennsylvania Facilities are not achieved, (2) if the discount rate increases, (3) if terminal growth rates decrease or (4) if market multiples decrease.
Other Intangible Assets	Other Intangible Assets Intangible assets relate primarily to the Pennsylvania Facilities, Mohegan Sun, MBC, Mohegan Lacrosse and Mohegan Golf. In connection with the acquisition of the Pennsylvania Facilities, the Authority recorded a slot machine license intangible asset of $214.0 million. In October 2006, a one-time slot machine license fee of $50.0 million was paid to the Pennsylvania Gaming Control Board (the “PGCB”) and added to the existing slot machine license intangible asset. In June 2010, a one-time table game certificate fee of $16.5 million was paid to the PGCB and classified as an intangible asset. The slot machine license and table game certificate intangible assets, with indefinite useful lives, are assessed as a single unit of accounting at least annually for impairment by comparing the fair value of the recorded assets to their carrying value. Their fair value is determined utilizing an income approach based on projected discounted cash flows from the Pennsylvania Facilities, exclusive of a required rate of return of all other assets and exclusive of capital expenditures requirements. If the carrying value exceeds the fair value, an impairment loss will be recognized to the extent that the carrying value exceeds the fair value. The income approach requires the Authority to make assumptions regarding future revenues and expenses, discount rates and the terminal value based on a perpetual growth rate of the Pennsylvania Facilities. As of September 30, 2015 and 2014, the Authority assessed the intangible assets for impairment and determined that no impairment existed. If any of the following occurs, the intangible assets may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from the Pennsylvania Facilities are not achieved, (2) if the discount rate increases or (3) if the terminal value decreases. In connection with a relinquishment agreement (refer to Note 11), Trading Cove Associates (“TCA”) granted the Authority an exclusive, irrevocable, perpetual, world-wide and royalty-free license with respect to trademarks and other similar rights, including the “Mohegan Sun” name. The Mohegan Sun trademark intangible asset of $119.7 million is deemed to have an indefinite useful life and is assessed at least annually for impairment by comparing its fair value to its carrying value. The fair value is determined utilizing the income approach – relief from royalty method based on projected revenues from Mohegan Sun and Mohegan Sun Pocono. If the carrying value exceeds the fair value, an impairment loss will be recognized to the extent that the carrying value exceeds the fair value. The income approach requires the Authority to make assumptions regarding future revenues, discount rates, royalty rate and the terminal value based on a perpetual growth rate of Mohegan Sun and Mohegan Sun Pocono. As of September 30, 2015 and 2014, the Authority assessed the Mohegan Sun trademark for impairment and determined that no impairment existed. If any of the following occurs, the Mohegan Sun trademark may be impaired and subject to a non-cash write-down in a future period, which could have a material adverse impact on the accompanying consolidated financial statements: (1) if estimates of projected cash flows from Mohegan Sun and Mohegan Sun Pocono are not achieved, (2) if the discount rate increases or (3) if the perpetual growth rate decreases. In connection with the acquisitions of the WNBA and NLL franchises and the assets of Pautipaug Country Club Inc., the Authority recorded franchise value intangible assets and a membership intangible asset, respectively. These intangible assets, with definite useful lives, are assessed for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. As of September 30, 2015 and 2014, the Authority assessed these intangible assets for impairment and determined that no impairment existed.
Debt Issuance Costs, Discounts and Premiums	Debt Issuance Costs, Discounts and Premiums Debt issuance costs incurred in connection with the issuance of revolving debt are capitalized and amortized to interest expense based on the related debt agreements on a straight-line basis. Unamortized amounts are included in other assets, net, in the accompanying consolidated balance sheets. Debt issuance costs incurred in connection with the issuance of non-revolving debt are recorded as a reduction to the carrying amount of the related debt and amortized to interest expense based on the effective interest method. Premiums received in connection with the issuance of debt are recorded as an increase to the carrying amount of the related debt and amortized to interest expense based on the effective interest method.
Self-insurance Accruals	Self-insurance Accruals The Authority is self-insured up to certain limits for costs associated with workers’ compensation, general liability and employee medical coverage. Insurance claims and reserves include accruals of estimated settlements of known claims, as well as accruals of estimates of incurred but not reported claims. These accruals are included in other current liabilities in the accompanying consolidated balance sheets. In estimating self-insurance accruals, the Authority considers historical loss experiences and expected levels of costs per claim. Claims are accounted for based on estimates of undiscounted claims, including claims incurred but not reported. The Authority believes that this method provides a consistent and effective way to measure these liabilities; however, changes in health care costs, accident frequency and severity and other factors could materially impact estimated liabilities. The Authority continuously monitors estimates and makes adjustments when necessary.
Unredeemed Momentum Dollars	Unredeemed Momentum Dollars The Authority maintains an accrual for unredeemed Momentum Dollars. This accrual is based on the estimated cost of Momentum Dollars expected to be redeemed as of the respective balance sheet date. The Authority assesses the adequacy of this accrual by periodically evaluating historical redemption experiences and projected trends related to the accrual. Actual results could differ from these estimates.
Base Jackpots	Base Jackpots Base jackpots represent the fixed minimum amount of payouts from slot machines for a specific combination. The Authority recognizes base jackpots as reductions to revenues when it becomes obligated to pay such jackpots.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The fair value amounts presented below are reported to satisfy disclosure requirements pursuant to authoritative guidance issued by the FASB pertaining to disclosures about fair values of financial instruments and are not necessarily indicative of amounts that the Authority could realize in a current market transaction. The Authority applies the following fair value hierarchy, which prioritizes the inputs utilized to measure fair value into three levels: • Level 1 - Quoted prices for identical assets or liabilities in active markets; • Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets or valuations based on models where the significant inputs are observable or can be corroborated by observable market data; and • Level 3 - Valuations based on models where the significant inputs are unobservable. The unobservable inputs reflect the Authority’s estimates or assumptions that market participants would utilize in pricing such assets or liabilities. The Authority’s assessment of the significance of a particular input requires judgment and may affect the valuation of financial assets and liabilities and their placement within the fair value hierarchy.
Revenue Recognition	Revenue Recognition The Authority recognizes gaming revenues as amounts wagered less prizes paid out. Revenues from food and beverage, hotel, retail, entertainment and other services are recognized at the time such service is performed. Minimum rental revenues are recognized on a straight-line basis over the terms of the related leases. Percentage rental revenues are recognized in the periods in which the tenants exceed their respective percentage rent thresholds.
Promotional Allowances	Promotional Allowances The Authority operates a program, without membership fees, for patrons at Mohegan Sun, Mohegan Sun Pocono and its managed property, Resorts Atlantic City. This program provides complimentary food and beverage, hotel, retail, entertainment and other amenities to patrons based on Momentum Dollars that are awarded for patrons’ gaming activities. Momentum Dollars may be utilized to purchase, among other things, items at restaurants and retail stores located within Mohegan Sun, Mohegan Sun Pocono and Resorts Atlantic City. Momentum Dollars may also be utilized at The Shops at Mohegan Sun and the Mohegan Sun gasoline and convenience center, as well as to purchase hotel services and tickets to entertainment events held at facilities located at Mohegan Sun, Mohegan Sun Pocono and Resorts Atlantic City. The retail value of complimentary items redeemed at facilities operated by the Authority is included in gross revenues and then deducted as promotional allowances to arrive at net revenues. The cost associated with reimbursing third-parties for the value of complimentary items redeemed at third-party outlets is included in gaming costs and expenses. In addition, the Authority offers ongoing promotional coupons to patrons for the purchase of food and beverage, hotel and retail amenities offered at Mohegan Sun and Mohegan Sun Pocono. The retail value of coupons redeemed at facilities operated by the Authority is included in gross revenues and then deducted as promotional allowances to arrive at net revenues. The cost associated with reimbursing third-parties for the value of coupons redeemed at third-party outlets is included in gaming costs and expenses.
Gaming Costs and Expenses	Gaming Costs and Expenses Gaming costs and expenses primarily include portions of gaming revenues that must be paid to the State of Connecticut and the PGCB. Gaming costs and expenses also include, among other things, payroll costs, expenses associated with the operation of slot machines, table games, poker, live harness racing and racebook, certain marketing expenditures and promotional expenses related to Momentum Dollar and coupon redemptions.
Advertising Costs and Expenses	Advertising Costs and Expenses Production costs are expensed the first time the advertisement takes place. Prepaid rental fees associated with billboard advertisements are capitalized and amortized over the terms of the related rental agreements. Advertising costs and expenses totaled $27.0 million, $26.7 million and $28.2 million for the fiscal years ended September 30, 2015, 2014 and 2013, respectively. As of September 30, 2015 and 2014, prepaid advertising was $432,000 and $142,000, respectively.
Corporate Costs and Expenses	Corporate Costs and Expenses Corporate costs and expenses represent an allocation of certain governmental and administrative costs, payroll costs, professional fees and various other expenses not directly related to the Authority’s operations at Mohegan Sun or Mohegan Sun Pocono. In addition, Corporate costs and expenses include costs associated with various gaming diversification efforts, which are expensed as incurred, except when reimbursable by third-parties.
Pre-Opening Costs and Expenses	Pre-Opening Costs and Expenses In accordance with authoritative guidance issued by the FASB pertaining to the reporting on the costs of start-up activities, pre-opening costs and expenses are expensed as incurred.
Investments in Unconsolidated Affiliates	Investments in Unconsolidated Affiliates The Authority, through its indirect wholly-owned subsidiary, MGA Holding NJ, holds a 10% ownership interest in Resorts Atlantic City and its associated gaming activities, including online gaming in the State of New Jersey. The Authority’s investment in Resorts Atlantic City is accounted for under the equity method as the Authority has significant influence.
Income Taxes	Income Taxes The Tribe is a sovereign Indian nation with independent legal jurisdiction over its people and land. Like other sovereign governments, the Tribe and its entities, including the Authority, are not subject to federal, state or local income taxes.
Seasonality	Seasonality The gaming market in the Northeastern United States is seasonal in nature, with peak gaming activities often occurring at Mohegan Sun and Mohegan Sun Pocono during the months of May through August. Accordingly, the Authority’s operating results for the fiscal year ended September 30, 2015 are not necessarily indicative of operating results for interim periods.
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued an accounting standard update on revenue recognition that will be applied to all contracts with customers. The update requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. It also requires more detailed disclosures to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. This guidance will be required to be applied on a retrospective basis, using one of two methodologies, and was to be effective for annual reporting periods beginning after December 15, 2016, with early application not being permitted. However, in July 2015, the FASB deferred the effective date by one year. This guidance will now be effective for annual reporting periods beginning after December 15, 2017, and interim reporting periods thereafter. Entities are permitted to adopt the guidance as of the original effective date. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations. In August 2014, the FASB issued an accounting standard update which provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. The update requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. It also requires management to provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. This guidance will be required for annual reporting periods ending after December 15, 2016, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations. In February 2015, the FASB issued an accounting standards update which amends existing requirements applicable to reporting entities that are required to evaluate whether certain legal entities should be consolidated. This guidance will be required to be applied either on a retrospective or modified retrospective basis and will be effective for annual reporting periods beginning after December 15, 2015, and interim reporting periods thereafter, with early application permitted. The Authority is currently evaluating the impact that this guidance will have on its financial position and results of operations.
