ORGANIZATION: [Abstract]
Nature of Operations [Text Block]	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 507-acre reservation situated in Southeastern Connecticut, adjacent to Uncasville, Connecticut. Under the Indian Gaming Regulatory Act of 1988 (“IGRA”), federally-recognized Indian tribes are permitted to conduct full-scale casino gaming operations on tribal land, 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 a 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 June 30, 2011, the following subsidiaries were wholly-owned by the Authority: Mohegan Basketball Club, LLC (“MBC”), Mohegan Golf, LLC (“Mohegan Golf”), Mohegan Commercial Ventures-PA, LLC (“MCV-PA”), Mohegan Ventures-Northwest, LLC (“Mohegan Ventures-NW”), Mohegan Ventures Wisconsin, LLC (“MVW”) and MTGA Gaming, LLC (“MTGA Gaming”). MBC owns and operates the Connecticut Sun, a professional basketball team in the Women's National Basketball Association (the “WNBA”). MBC currently owns a 3.8% membership interest in WNBA, LLC. Mohegan Golf owns and operates the Mohegan Sun Country Club at Pautipaug golf course in Southeastern Connecticut (“Mohegan Sun Country Club”). MCV-PA holds a 0.01% general partnership interest in Downs Racing, L.P., Backside, L.P., Mill Creek Land, L.P. and Northeast Concessions, L.P., while the Authority holds the remaining 99.99% limited partnership interest in each entity.

(“Downs Racing”) owns and operates Mohegan Sun at Pocono Downs, a gaming and entertainment facility situated on a 400-acre site in Plains Township, Pennsylvania, and several off-track wagering facilities located elsewhere in Pennsylvania (collectively, the “Pennsylvania Entities”). The Authority views Mohegan Sun and the Pennsylvania Entities as two separate operating segments. Mohegan Ventures-NW and the Tribe hold 49.15% and 7.85% membership interests in Salishan-Mohegan, LLC (“Salishan-Mohegan”), respectively, which was formed with an unrelated third-party to participate in the development and management of a proposed casino to be owned by the federally-recognized Cowlitz Indian Tribe of Washington (the “Cowlitz Tribe”) and to be located in Clark County, Washington (the “Cowlitz Project”). 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”).
