PURCHASE, New York: Indra K Nooyi (51), occupant of the ceo's seat at Pepsico for just three months and five days, is set to add the role of chairwoman to her portfolio when incumbent Steven Reinemund retires on May 2.

Already one of the most senior female executives in North America, Indian-born Nooyi's elevation to the Pepsico chair will make her second only to Patricia A Woertz of soya-bean leviathan Archer Daniels Midland as America's most highly-ranked businesswoman.

An accountant by training, Nooyi joined Pepsico in 1994 and directed the group's worldwide strategy for over a decade. She was the primary architect of PepsiCo's restructuring and transformation, including the merger with Quaker Oats and the acquisition of Tropicana.

She was elected to PepsiCo's board of directors in 2001 and to the ceo role last year, when she also succeedeed Reinemund. "I'm incredibly honored by the board's confidence," Nooyi said in a statement.
