On May 28, 2007, it was announced that the Louisville Metro Council was to propose an arena-financing deal that would save city taxpayers $3.4 million/year, or $100 million over three decades. The proposal, required the arena officials to exhaust other revenue sources, such as naming rights and luxury suite sales, before asking the metro government to pay more than its minimum pledge. The minimum pledge was $206 million towards the construction of the arena in annual installments between 2010 and 2039. Under the deal, the Louisville Arena Authority can ask the local government for up to $3.5 million more a year to cover the debt only if at least five other sources are drained. If the Louisville Arena Authority would have to use additional city funds for two straight years, the Louisville Metro Council has the right to audit the arena's revenues.
