COWLITZ PROJECT	COWLITZ PROJECT: On January 1, 2019, the Mohegan Tribe exchanged its interest in Salishan-Mohegan and SMDC for total consideration of $10.0 million, which the Company believes represented its fair value. Accordingly, the Company now owns 100% of Salishan-Mohegan, which developed and currently manages the Cowlitz Project. The Cowlitz Project opened in April 2017. Through SMDC, Salishan-Mohegan, along with Salishan Company, LLC (“Salishan Company”), an unrelated entity, also holds the development rights to any future development at ilani Casino Resort. Under the terms of Salishan-Mohegan's development agreements, development fees of $976,000, $570,000 and $7.3 million were earned for the fiscal years ended September 30, 2019, 2018 and 2017, respectively. Under the terms of Salishan-Mohegan's management agreement, Salishan-Mohegan manages, operates and maintains the casino resort through May 2024 for a fee representing 24% of net revenues, as defined under the management agreement. Management fees earned by Salishan-Mohegan totaled $27.9 million, $13.5 million and $6.0 million for the fiscal years ended September 30, 2019, 2018 and 2017, respectively. Salishan-Mohegan advanced funds for the Cowlitz Project before financing was obtained for the project. In December 2015, financing was obtained, which provided funding for the remaining construction costs of the project and the repayment of a portion of amounts previously advanced by the Company. As of September 30, 2018, the Salishan-Mohegan notes, including accrued interest at an annual rate of approximately 13.0%, totaled $104.4 million and were recorded within notes receivable. On December 4, 2018, the Company received $106.6 million from the Cowlitz Tribal Gaming Authority. This amount represented the full repayment of the then-outstanding Salishan-Mohegan notes and accrued interest, through the repayment date, totaling $32.0 million and $74.6 million, respectively. In April 2017, pursuant to a membership interest redemption and withdrawal agreement, Salishan-Mohegan agreed to redeem the membership interest in Salishan-Mohegan that was previously held by Salishan Company, LLC (“Salishan Company”) for a redemption price of $114.8 million (the “Redemption Price”), which was determined by binding arbitration. The Redemption Price represented a $68.5 million redemption liability based on the present value of the Redemption Price, utilizing the Company’s credit adjusted risk-free investment rate. The amount of the redemption liability approximated the carrying value of Salishan Company's membership interest at the redemption date and, accordingly, no gain or loss was recorded in connection with this transaction. The redemption liability is payable through a promissory note (the “Redemption Note Payable”) issued by Salishan-Mohegan. The Redemption Note Payable is payable in monthly installments of $1.9 million over a five-year period, commencing in May 2019. The Company recognizes interest expense relating to the amortization of discount to the Redemption Price, utilizing the effective yield method.
