Pacers, Colts owners on Forbes' billionaires list

Indiana Pacers owner Herb Simon and Indianapolis Colts owner Jim Irsay are again included on the annual Forbes' billionaires' list. Simon's net worth was estimated at $2.9 billion, putting him at No. 628 on the list. Irsay's net worth was estimated at $1.8 billion, leaving him at No. 1,105 on the list.

Forbes on Simon: "The sons of a New York tailor, Simon and his brother Melvin (who died in 2009) grew up working class in the Bronx. In 1960 they founded the precursor to Simon Property Group. It's now one of the world's largest REITs, with 228 shopping malls and retail strips. It spans 242 million square feet across America, Europe and Asia. Melvin's son, David, has been the CEO since 1995. The biggest jump in his assets, though, comes from owning the Indiana Pacers, which Forbes' now estimates are worth $310 million more than 2014. Herb also sits on the board of Cheesecake Factory. He is a father of eight and on his third marriage — this time to a former Miss Universe from Thailand. They regularly donate to charities for Thai children."

Forbes on Irsay: "After serving a six-game suspension from the NFL for a 2014 DWI guilty plea, Irsay returned to his Indianapolis Colts in time to see them make a run to the playoffs for the third year in a row and for the 14th time in 16 seasons. Following a mostly lackluster 25-year run under the ownership of Irsay's father Robert, the franchise, worth over $1.3 billion net of debt, has been a model of consistency since James took over in 1997. An avid collector, Irsay owns guitars from assorted rock legends like Jerry Garcia and Elvis Presley, and an original manuscript of the famous Jack Kerouac novel 'On the Road.' "

Los Angeles Clippers owner Steve Ballmer is listed as the world's 35th wealthiest billionaire for 2015. Michael Jordan, owner of the Charlotte Hornets, was a newcomer on the list, at No. 1,741 with $1 billion.
