Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Slot Win Contribution The Mohegan 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 Mohegan Tribe and the Mashantucket Pequot Tribe. Annual Slot Win Contribution payments are the lesser of: (i) 30% of gross revenues from slot machines and (ii) the greater of 25% of gross revenues from slot machines or $80.0 million. Pennsylvania Slot Machine Tax The Pennsylvania Race Horse Development and Gaming Act stipulates that holders of Category One slot machine licenses, including Mohegan Pennsylvania, must pay a portion of revenues from slot machines and other assessments to the PGCB (collectively, the “Pennsylvania Slot Machine Tax”). The Pennsylvania Slot Machine Tax approximates 52% of gross revenues from slot machines, plus an annual $10.0 million slot machine operation fee. Niagara Resorts Casino Operating and Services Agreement Thresholds We operate the Niagara Resorts under the terms of a 21-year Casino Operating and Services Agreement with the Ontario Lottery and Gaming Corporation. Annual Threshold amounts under the Casino Operating and Services Agreement are contractually established and vary from year to year. If gaming revenues are less than the Threshold for any given year, we are obligated to make a payment to cover the related shortfall (refer to Note 2). Mohegan Casino Las Vegas Lease In July 2019, MGNV, LLC entered into a casino lease agreement with JC Hospitality, LLC, which developed the former Hard Rock Hotel and Casino in Las Vegas, Nevada, into an integrated resort under the Virgin Hotels brand. We operate Mohegan Casino Las Vegas, the gaming portion of the integrated resort. During the initial term of the 20-year lease agreement, we are required to make annual minimum rent payments of $9.0 million, subject to escalators which could result in annual minimum rent payments of up to $15.0 million, plus consumer price index inflators and additional common area maintenance fees. Annual minimum rent payments commenced upon the first anniversary of the Lease Commencement Date, as defined under the lease agreement, and continue until the end of the lease term, which concludes in 2041, subject to additional extensions at our option. Priority Distribution We and the Mohegan Tribe are parties to a perpetual agreement, which requires us to make payments to the Mohegan Tribe to the extent of our Net Cash Flow, as defined, subject to a minimum payment of $40.0 million per calendar year. Purchase and Other Contractual Obligations As of September 30, 2022, we were contractually committed to purchase goods and services totaling $10.2 million, of which $3.0 million is expected to be incurred in fiscal 2023. Litigation We are a defendant in various claims and legal actions resulting from our normal course of business, primarily relating to personal injuries to customers and damages to customers' personal assets. We estimate litigation claims expense and accrue for such liabilities based upon historical experience. In management's opinion, the aggregate liability, if any, arising from such legal actions will not have a material impact on our financial position, results of operations or cash flows.
