Marsh Acquires Trion

Marsh & McLennan Agency L.L.C. has acquired Trion Group Inc., a large, privately held employee benefits firm.

Marsh & McLennan Agency, a unit of a brokerage subsidiary of Marsh & McLennan Companies Inc., New York (NYSE:MMC), says it bought Trion, Conshohocken, Pa., to implement a strategy that calls for using acquisitions to build a national benefits and property-casualty insurance operation.

The Trion deal is the sixth Marsh & McLennan Agency has made since November 2009, and the Trion deal has made the agency the 12th largest in the United States, the agency says.
