Just 31, James (Jimmy) Levin, head of global credit and executive managing director at $40.2 billion hedge fund firm Och-Ziff Capital Management Group, has already enjoyed the kind of success that many on Wall Street only dream of. Having fast achieved stud status in 2012, when he made a $7.5 billion wager on structured-credit debt investments that raked in $2 billion for Och-Ziff, Levin is being duly rewarded. Last year he was made a limited partner in the firm and as a result was granted a $119 million compensation package. The deal consists of shares, most of which will vest in ten equal installments over the next decade. Clearly, Och-Ziff wants to keep Levin who is 13 years the junior of the next-youngest member of its executive committee and 22 years younger than CEO Daniel Och around for the long haul. Levin previously worked for Purchase, New Yorkbased Sagamore Hill Capital Management and New Yorks Dune Capital Management after earning a BA in computer science from Harvard University.
