MMC CEO not to step down?

Marsh's stock surged as much as 10% in the early afternoon after the Financial Times reported that embattled Chairman and Chief Executive Jeffrey Greenberg would resign "within hours." The newspaper's Web site also reported that Jules Kroll, 63, founder of corporate security firm Kroll Inc. and a vice chairman of insurance brokerage unit Marsh Inc., would succeed Greenberg. But Kroll quickly issued a statement denying the report as "erroneous," cooling enthusiasm for Marsh shares. The stock closed up 7.8% at $26.79 on the New York Stock Exchange.
