Via the Sun-Sentinel's Brittany Wallman:
"In a letter from the company that owns the Florida Panthers, Sunrise Sports and Entertainment, President Michael Yormark told the county mayor and commissioners that he’d seek the loan to pay for improvements to the center ice seating section and the executive suites."
From the Sun-Sentinel's Sarah Talalay:
Sunrise Sports & Entertainment's Arena Operating Co., which operates the home of the Panthers, is seeking to cut its annual payments by $2.5 million annually through 2016, and then raise them by about $1 million a year starting in 2017.
The restructuring is expected to cost $23 million more over the life of the loan, which would also be extended a year, and be paid by Sunrise Sports, not the county.
