MMC Appoints Ben Allen Chief Executive Officer of Kroll

Marsh & McLennan Companies, Inc. (NYSE: MMC) today said it named Ben Allen as President and Chief Executive Officer of Kroll, the company’s risk consulting and technology group. In his new role, Mr. Allen succeeds Simon V. Freakley, who will serve as Chief Executive Officer of a newly formed MMC corporate advisory and restructuring unit. "As one of the world’s top risk consultants, we require strong leadership across MMC,” said Brian Duperreault, President and Chief Executive Officer of MMC. "As our clients increasingly rely on a combination of technology and consulting to help them assess and mitigate risk, Ben is the ideal executive to oversee Kroll. I am also pleased that Simon has agreed to lead corporate advisory and restructuring as a separate consulting business at MMC. This structure gives greater clarity to our organization and will allow us to serve clients more effectively.” Both Mr. Allen and Mr. Freakley will report to Mr. Duperreault. "I consider it an honor to serve as CEO of Kroll at this important time,” Mr. Allen said. "Our clients face new challenges every day and must be able to assess and manage risks to their business quickly. Kroll's unique combination of best-in-class consulting, technology-enabled solutions and global reach allows us to create customized solutions to help clients respond to and mitigate risks that arise from conducting business in a complex environment.” Mr. Allen, based in New York, has managed Kroll’s daily operations since being appointed Chief Operating Officer in July 2007. Previously, he was President of Kroll Ontrack, the firm’s legal technologies and data recovery unit, since 2001. Prior to Kroll’s acquisition of Ontrack, Mr. Allen was President and CEO of ONTRACK Data International, Inc., and served in several roles for that firm including as Chief Operating Officer and general manager of the U.K. and France. Mr. Freakley said, "We have already seen an increase in the demand for our services in the current economic climate. This reorganization will allow us to focus resources more intently on assisting global clients as they confront increasingly challenging restructuring issues.” Prior to his appointment as President and CEO of Kroll, Mr. Freakley served as President of Kroll's Corporate Advisory & Restructuring Group from September 2002 to October 2004.
