NEW YORK, NEW YORK, January 18, 2007 — Marsh & McLennan Companies, Inc. (NYSE: MMC) today announced that David A. Nadler has been appointed vice chairman, Office of the CEO, of MMC. Nadler assumes his new position immediately.

In his role as vice chairman, Nadler, 58, will co-lead with fellow vice chairman Mathis Cabiallavetta global efforts to leverage MMC's client relationships across its businesses.

Nadler will report to Michael G. Cherkasky, president and chief executive officer of MMC, and will serve as a member of the MMC executive committee. "Leveraging MMC's resources and relationships across all of our operating units is a key component of fueling additional growth and shareholder value for MMC," said Cherkasky. "David's talents are immense and he is uniquely qualified to co-lead this effort by virtue of his own professional work at the highest levels of business, his sterling professional reputation and his intimate knowledge of MMC's business."

Nadler will continue to directly serve clients as a senior partner and chairman of Mercer Delta Consulting, but a significant amount of his time will now be directed to his new duties as vice chairman.

Nadler said, "I'm very excited by this opportunity to work with our colleagues across all of the MMC businesses. We have great brands and outstanding professionals. I believe that by working together in a spirit of partnership, we can create even greater value for our clients."
