Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Basis of Presentation	Organization and Basis of Presentation Organization The Mohegan Tribal Gaming Authority d/b/a Mohegan Gaming & Entertainment (the “Company,” “we,” “us,” or “our”) was established by the Mohegan Tribe of Indians of Connecticut (the “Mohegan Tribe”) in July 1995. We have the exclusive authority to conduct and regulate gaming activities for the Mohegan Tribe on tribal lands and the non-exclusive authority to conduct such activities elsewhere. The Mohegan Tribe is a sovereign Indian nation with independent legal jurisdiction over its people and land. We are primarily engaged in the ownership, operation and development of integrated entertainment facilities. We currently own two facilities in the United States and operate five facilities in the United States and Canada. We are also currently developing a facility in South Korea, the Inspire Entertainment Resort located adjacent to the Incheon International Airport (“Inspire Korea”). Impact of the COVID-19 Pandemic In March 2020, the World Health Organization declared the outbreak of COVID-19 a global pandemic and the United States federal government declared it a national emergency. The spread of COVID-19 has affected most segments of the global economy, including our operations. In March 2020, we temporarily suspended operations at our properties in the United States and Canada to ensure the health and safety of our employees, guests and the surrounding communities in which we operate, consistent with directives from various governmental bodies. All of our properties in the United States were reopened by July 2020. Our properties in Canada reopened in July 2021, but were temporarily closed again from January 5, 2022 through January 30, 2022, due to a resurgence of COVID-19. COVID-19 has had a significant impact on our operations, the full extent of which depends on future developments which are highly uncertain and cannot be predicted with confidence. Such developments include the following: • the duration of COVID-19 or the extent of any resurgence or variants of COVID-19; • the manner in which our guests, suppliers and other third parties respond to COVID-19, including the perception of safety and health measures we implemented; • new information that may emerge concerning the severity of COVID-19 and the actions to contain or treat it; • general economic conditions; and • consumer confidence. Accordingly, we cannot reasonably estimate the extent to which COVID-19 will further impact our future financial condition, results of operations and cash flows. We could experience other potential adverse impacts as a result of COVID-19, including, but not limited to, charges from further adjustments to the carrying value of our intangible assets, as well as other long-lived asset impairment charges. Actual results may differ materially from our current estimates as the scope of COVID-19 evolves, depending largely, but not exclusively, on the duration and extent of our business disruptions. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”) for interim financial information and with instructions to Form 10-Q and Rule 10-01 of Regulation S-X. In accordance with Rule 10-01, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by US GAAP for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by US GAAP. All adjustments, including normal recurring accruals and adjustments, necessary for a fair statement of our operating results for the interim period, have been included. Our results of operations for these interim periods are not necessarily indicative of the operating results for other quarters, for the full fiscal year or any other period, particularly given the impact of COVID-19 as discussed above. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021. The preparation of financial statements in conformity with US GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. Similar to other sovereign governments, the Mohegan Tribe and its entities, including the Company, are not subject to United States federal income taxes. However, certain of our non-tribal entities are subject to income taxes in various state and local jurisdictions within the United States and in Canada. Inspire Korea The initial phase of Inspire Korea primarily consists of an integrated entertainment resort. Design and construction work was temporarily paused in September 2020 while we were in the process of securing the necessary financing for the project, which was completed in November 2021 (see Note 2). During this temporary pause in construction, Inspire Korea obtained approval to modify its development plan and adjust the timing of a future sub-phase of this initial phase of the project. On December 27, 2021, Inspire Korea elected to terminate a licensing arrangement for a previously-planned sub-phase and discontinue related design work. As a result, we recognized an intangible asset impairment of $12.9 million related to the licensing arrangement and a tangible asset impairment of $17.7 million on the related construction in progress. Recently Issued Accounting Pronouncements ASU 2019-12 In December 2019, the Financial Accounting Standards Board (the “FASB”) issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which simplifies various aspects related to the accounting for income taxes. This new standard removes certain exceptions to the general principles in ASU 2019-12 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 was effective for annual reporting periods beginning after December 15, 2020. There was no effect on the Company’s financial statements from adopting this new standard. ASU 2021-10 In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (“ASU 2021-10”), which requires business entities to provide certain disclosures about government transactions that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance. ASU 2021-10 is effective for annual reporting periods beginning after December 15, 2021. The Company is currently evaluating the effect ASU 2021-10 will have on its disclosures.

Inspire Korea Financing Inspire Korea Credit Facility On September 24, 2021, Inspire Korea entered into a loan agreement providing for a loan commitment of up to 1.04 trillion Korean won (“KRW”) in two tranches (the “Inspire Korea Credit Facility”), comprised of a 740.0 billion KRW credit facility (the “Tranche A Facility”) and a 300.0 billion KRW credit facility (the “Tranche B Facility”). The Inspire Korea Credit Facility is being used to pay for the construction, operation, financial and other project costs in connection with Inspire Korea (see Note 1). All obligations under the Inspire Korea Credit Facility are secured by liens on substantially all assets of, and equity interests in, Inspire Korea (subject to certain exceptions and limitations). The Inspire Korea Credit Facility matures 48 months after the date of the first draw, which was November 29, 2021.

The Inspire Korea Credit Facility may not be voluntarily prepaid in whole or in part until one year after the date of the first draw. After such date, any voluntary prepayment requires a prepayment fee as defined in the Inspire Korea Credit Facility agreement. Loans outstanding under the Tranche A Facility bear interest at a fixed rate of 5.4% per annum or a floating rate equal to the sum of a base rate and an applicable margin (as defined in the Inspire Korea Credit Facility agreement). Loans outstanding under the Tranche B Facility bear interest at a fixed rate of 7.0% per annum or a floating rate equal to the sum of a base rate and an applicable margin (as defined in the Inspire Korea Credit Facility agreement). The Inspire Korea Credit Facility includes an interest reserve whereby a portion of loan proceeds is reserved for payment of interest. Interest on Tranche A Facility loans is fully reserved and interest on Tranche B Facility loans is reserved for 36 months. If any portion of the Inspire Korea Credit Facility is undrawn, Inspire Korea is required to pay a 0.3% commitment fee on the undrawn amount. The Inspire Korea Credit Facility contains certain customary covenants applicable to Inspire Korea, including covenants governing: incurrence of indebtedness, incurrence of liens, investments, mergers or consolidations, asset sales, acquisitions of assets, the payment of dividends and other distributions and affiliate transactions. In addition, the Inspire Korea Credit Facility includes other covenants, representations and warranties and events of default that are customary for financing transactions of this type. In connection with the Inspire Korea Credit Facility, the Company entered into a credit enhancement support agreement to provide up to $100.0 million credit enhancement support for Inspire Korea’s payment of principal, interest and other sums due under the Inspire Korea Credit Facility. The Company incurred $59.1 million in costs in connection with this transaction during fiscal 2022. These debt issuance costs were reflected as a debt discount and are being amortized over the term of the Inspire Korea Credit Facility using the effective interest method . MGE Korea Term Loan On November 4, 2021, MGE Korea Limited (“MGE Korea”), an indirect wholly-owned subsidiary of the Company and parent company of Inspire Korea, entered into a $275.0 million secured term loan facility agreement (the “MGE Korea Term Loan”). MGE Korea received funding from the MGE Korea Term Loan on November 24, 2021 (the “Utilisation Date”). The MGE Korea Term Loan was primarily used to make a capital contribution to Inspire Korea in order to partially fund construction-related costs for Inspire Korea. The MGE Korea Term Loan matures 66 months after the Utilisation Date. The MGE Korea Term Loan bears payment-in-kind interest at a rate of 17.0% per annum, to be compounded and capitalized at the end of each quarter, or paid in cash if so elected by MGE Korea. If the MGE Korea Term Loan is voluntarily prepaid, if certain mandatory prepayment events are triggered or if it is repaid following a notice of acceleration, MGE Korea must pay a prepayment fee (as defined in the MGE Korea Term Loan agreement). The MGE Korea Term Loan is secured by a fixed charge over 100% of MGE Korea’s share capital and a debenture over the assets of MGE Korea (subject to certain exceptions and limitations). The MGE Korea Term Loan contains certain customary covenants, including covenants governing: incurrence of indebtedness, incurrence of liens, payment of dividends and other distributions, disposals, acquisitions and investments, arm’s length transactions, mergers and the development and management of Inspire Korea. In addition, the MGE Korea Term Loan includes financial maintenance covenants pertaining to net leverage and debt service coverage of MGE Korea and Inspire Korea, and contains a requirement that Inspire Korea maintain a minimum cash balance in the amounts set forth in the MGE Korea Term Loan. The MGE Korea Term Loan also contains customary events of default relating to, among other things, failure to make payments, breach of covenants and breach of representations. The Company incurred $10.0 million in costs in connection with the MGE Korea Term Loan during fiscal 2022. These debt issuance costs were capitalized and are being amortized over the term of the MGE Korea Term Loan. In addition, the allocation of proceeds to the issuance of warrants and associated put option (see below) resulted in an original issue discount on the MGE Korea Term Loan of $84.8 million, which will also be amortized over the term of the MGE Korea Term Loan using the effective interest method. MGE Korea Warrant Agreement In connection with the MGE Korea Term Loan, on November 4, 2021, MGE Korea Holding III Limited (“MGE Korea Holding III”), the parent company of MGE Korea, entered into a warrant agreement (the “Warrant Agreement”) to issue detachable warrants (the “Warrants”). The Warrants can be converted into up to a total of 4,400 shares of capital in MGE Korea Holding III at an initial exercise price of $0.01 per share. At the time of issuance, the Warrants represented 22.0% of the fully-diluted share capital of MGE Korea Holding III. The Warrants are generally exercisable at any time after the third anniversary of the Utilisation Date (November 2024) until the tenth anniversary of the Utilisation Date (November 2031), but may be exercised earlier upon certain triggering events defined in the Warrant Agreement. Upon the earlier of (i) the tenth anniversary of the Utilisation Date (November 2031) and (ii) the consummation of an Exit Event (as defined in the Warrant Agreement), all unexercised Warrants will expire. Warrant holders do not have any rights held by holders of shares in the capital of MGE Korea Holding III to vote or to receive dividends and other distributions (other than as set forth in the Warrant Agreement). Warrant holders and shareholders of MGE Korea Holding III have certain preemptive rights in relation to any proposed issuance of equity securities by MGE Korea Holding III or certain affiliates (as defined in the Warrant Agreement), subject to customary exceptions. Holders of unexercised Warrants have the right to require the parent of MGE Korea Holding III (the “Parent”) to purchase all of the unexercised Warrants that they hold at certain relevant times (the “Put Option”). In turn, the Parent has the right to require the holders of unexercised Warrants to sell all of the unexercised Warrants they hold at certain relevant times (the “Call Option”). Both the Put Option and the Call Option are exercisable at any time in the period from (and including) the date six years and six months after the Utilisation Date (May 2028) until the tenth anniversary of the Utilisation Date (November 2031). The aggregate cash purchase price for both the Put Option and the Call Option equals the higher of: (i) the fair market value of the relevant unexercised Warrants and (ii) $110.0 million, multiplied by a fraction, the numerator of which is the number of the relevant unexercised Warrants and the denominator of which is the total number of Warrants. The Warrants and the Put Option are classified as long-term liabilities and are re-measured at their estimated fair values at each reporting date. The estimated fair value of the Warrants and the Put Option was determined by utilizing the income approach (discounted cash flow method) and a binomial lattice model. This valuation approach utilized Level 3 inputs. The primary unobservable inputs utilized were the discount rate, which was 10.5%, and the expected volatility of the underlying stock price, which was 50.0%. Debt issuance costs incurred during fiscal 2022 and allocated to the Warrants and the Put Option totaling $4.2 million were expensed on the Utilisation Date and recorded within Corporate costs and expenses.

Segment Reporting	Segment Reporting The Company, either directly or through subsidiaries, operates Mohegan Sun, along with its other Connecticut operations (the “Connecticut Facilities”), Mohegan Sun Pocono, along with its other Pennsylvania operations (the “Pennsylvania Facilities”) and the MGE Niagara Resorts. Certain other properties that are managed or under development by the Company are identified as the management, development and other reportable segment. The Company's chief operating decision maker currently reviews and assesses the performance and operating results and determines the proper allocation of resources to the Connecticut Facilities, the Pennsylvania Facilities, the MGE Niagara Resorts and the properties managed or under development on a separate basis. Accordingly, the Company has four separate reportable segments: (i) Mohegan Sun, which includes the operations of the Connecticut Facilities, (ii) Mohegan Sun Pocono, which includes the operations of the Pennsylvania Facilities, (iii) the MGE Niagara Resorts and (iv) management, development and other.

In accordance with Rule 10-01, the accompanying unaudited condensed consolidated financial statements do not include all of the information and footnotes required by US GAAP for complete consolidated financial statements. The accompanying year-end condensed consolidated balance sheet was derived from audited financial statements, but does not include all disclosures required by US GAAP. All adjustments, including normal recurring accruals and adjustments, necessary for a fair statement of our operating results for the interim period, have been included. Our results of operations for these interim periods are not necessarily indicative of the operating results for other quarters, for the full fiscal year or any other period, particularly given the impact of COVID-19 as discussed above. The accompanying condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021. The preparation of financial statements in conformity with US GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures of contingent assets and liabilities. Similar to other sovereign governments, the Mohegan Tribe and its entities, including the Company, are not subject to United States federal income taxes. However, certain of our non-tribal entities are subject to income taxes in various state and local jurisdictions within the United States and in Canada.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements ASU 2019-12 In December 2019, the Financial Accounting Standards Board (the “FASB”) issued ASU 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes” (“ASU 2019-12”), which simplifies various aspects related to the accounting for income taxes. This new standard removes certain exceptions to the general principles in ASU 2019-12 and clarifies and amends existing guidance to improve consistent application. ASU 2019-12 was effective for annual reporting periods beginning after December 15, 2020. There was no effect on the Company’s financial statements from adopting this new standard. ASU 2021-10 In November 2021, the FASB issued ASU 2021-10, “Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance” (“ASU 2021-10”), which requires business entities to provide certain disclosures about government transactions that are accounted for by applying a grant or contribution accounting model by analogy to other accounting guidance. ASU 2021-10 is effective for annual reporting periods beginning after December 15, 2021. The Company is currently evaluating the effect ASU 2021-10 will have on its disclosures.
