Marsh and McLennan Companies

This case deals with the problems facing MMC in three of its key business areas, which surfaced in quick succession in 2003 and 2004. Its focus is primarily on the reputation risks facing the firm, and how shareholder value can be destroyed when such risks materialize. In two of the three cases, the market capitalization losses dwarf the accounting losses attribuable to fines, penalties, restitution, restructuring, etc., associated with the events.
