With its acquisition of Bear Stearns set to close this week, JPMorgan is losing another member of its investment banking management committee, this one to a major hedge fund.

Bill King will join Chicago-based Citadel Investment Group as its first head of securitized products. At JPMorgan, he served as co-head of global securitized products, a post he has shared with Bear Stearns’ Mike Nierenberg, who will now run the group on his own.

King joins former vice chairmen and former management committee members Jeff Mayer and Craig Overlander at the exit. Mayer and Overlander handed in their resignations last week.
