The board of American International Group Inc. has voted unanimously to make Robert Willumstad, former president of Citigroup Inc., the company’s chairman.
Willumstad, 61, will succeed Frank Zarb, who has served as interim chairman since April 2005. Zarb, in turn, succeeded Maurice Greenberg.
Zarb will continue to be an AIG director and a non-voting member of each standing AIG board committee, AIG says.
Willumstad was elected to the AIG board in January.
