Billionaire hedge fund manager John Paulson, who made a killing from calling the 2008 U.S. housing collapse, is reportedly converting his hedge funds into a family office that solely manages his fortune. 

"After considerable reflection and careful thought, Paulson & Co. will convert into a private investment office and return all external investor capital," Paulson wrote in a letter to investors, according to Bloomberg News.

His hedge funds were well-positioned for the historic market turmoil earlier this year with his big bets on gold, regulatory filings showed. Here's a look at Paulson's biggest holdings before the transition. The New York-based investment adviser Paulson & Co. managed about $9 billion as of last year.
