Marsh & McLennan CFO Wittman leaving for Google

NEW YORK—Vanessa A. Wittman has resigned as executive vp and chief financial officer of Marsh & McLennan Cos. Inc. to work for Google Inc., Marsh said in a filing with the U.S. Securities and Exchange Commission on Monday.

The filing said Ms. Wittman was leaving “in order to accept a senior role at Google” and that she would “assist the company in the transition of her responsibilities.”

The filing did not specify what the senior position was, and Google did not respond immediately to a request for Ms. Wittman's new title.

She will leave this month, according to the filing.

The filing said J. Michael Bischoff, Marsh & McLennan's vp of corporate finance, will assume the role of principal financial officer on an interim basis until a new principal financial officer is appointed.

Ms. Wittman joined Marsh & McLennan in 2008.
