The resignation comes amid rising revenue and core earnings at New York-based Marsh & McLennan, which also provides consulting and other services. Wittman joined the company in 2008 amid a tough environment for the insurance brokerage industry as well as troubles from a costly 2005 agreement to settle bid-fixing charges.
Wittman notified the company of her plans last week and plans to leave in late March, Marsh & McLennan disclosed in a regulatory filing Monday. J. Michael Bischoff, VP of corporate finance, will serve as interim finance chief as the company looks at both internal and external candidates to succeed Wittman, a company spokesman said.
Wittman's tech industry experience includes roles at 360networks, a Seattle-based company that restructured and emerged from bankruptcy protection in 2002, and Microsoft Corp., according to Marsh & McLennan's website. She helped oversee one of the most complex bankruptcy cases in U.S. history as CFO of the now-defunct cable operator Adelphia Communications Corp.
