FTX owes Miami-Dade County, the owners of the facility formerly known as FTX arena, $16.5 million, according to a contract signed last year between the bankrupt exchange.

According to the contract, the $135 million deal is amortized over 19 years. The contract also says that in the event of a default by FTX, which includes an “insolvency event”, the exchange will be liable to pay three years of contract fees, within 60 days. After paying $14 million during signing of the contract, FTX will now be liable to pay $16.5 million for the subsequent three years. If the payment is not paid within ten business days, the County says it has the rights to charge 12% interest per anum until the payment is made.
