186. Ira Rennert
In 2015, a jury found Rennert liable for looting his Magnesium Corp. of America, from which the plaintiff claimed he took dividends to build his $249 million (appraised value) mansion in the Hamptons. An appeals court judge ruled in March that Rennert owed $213 million to the trustee of the magnesium company’s estate. He petitioned the U.S. Supreme Court in August, though as of press time the case has not been accepted by the court. Rennert, a former credit analyst, made a fortune issuing junk bonds secured by metal companies he acquired and has built an industrial empire that claims to haul in more than $5 billion in revenue a year.
