Marex Spectron Managing Director Prentice Leaves Firm

(Corrects spelling of CEO name in second, last paragraph.)

Marex Spectron Group, a closely held commodities broker, said Gavin Prentice, its managing director and global head of sales, is leaving the firm.

“Gavin is a part of the core DNA of Marex Spectron, a 20- year veteran and a huge figure in the metals trading industry,” John Wall, chief executive officer of the company, said in an e- mailed statement. “We will miss him greatly but we respect his decision to take a break to plan the next stage of his career.”

Prentice, 49, a former head of metals at Refco Overseas Ltd. in London, according to data compiled by Bloomberg, was appointed to an advisory group of the London Metal Exchange after it was acquired in December by Hong Kong Exchanges & Clearing Ltd. (388) for 1.39 billion pounds ($2.1 billion).

Marex, a London-based firm which describes itself as the world’s largest privately owned commodities broker, has offices in Hong Kong and Singapore as well as U.S. operations in New York, Connecticut and Washington state.

Marex is controlled by JRJ Group, the London-based investment firm set up by former Lehman Brothers Holdings Inc. bankers Jeremy Isaacs and Roger Nagioff, Trilantic Capital Partners and BXR Group. The company may increase its staff by as much as 20 percent as it expands in Asia and the U.S., Wall said this month.
