The old structure had two divisions: PepsiCo North America and PepsiCo International, which ran their own food and beverage operations.

"Given PepsiCo's robust growth in recent years, we are approaching a size which we can better manage as three units instead of two," PepsiCo chief executive officer Indra Nooyi said in a statement.

The snack food business will include Frito-Lay North America, Quaker and its fast-growing Sabritas and Gamesa brands in Mexico. The beverages unit includes Pepsi-Cola North American, Gatorade, Tropicana and all Latin American beverage businesses.

The changes effectively moves Mexico and all Central and South American businesses, previously part of the international division, into the new divisions and create two new positions of chief executive officer, for the newly formed PepsiCo Americas Foods and PepsiCo Americas Beverages.

The company, which has headquarters in Purchase, N.Y., said its Americas foods division will account for about 45 percent of its revenue while its Americas beverages unit will make up 30 percent. Its international division will account for about 25 percent.

PepsiCo International CEO Mike White keeps his current position and takes on new responsibilities such as procurement and technology. PepsiCo International includes all of PepsiCo's UK, Europe, Middle East and Africa units.

Dawn Hudson, CEO and president of Pepsi-Cola North America, is leaving the company. She has worked at PepsiCo for 11 years. A spokeswoman declined to give more details.

The company said it will complete the reorganization at of the start of its fiscal 2008 year.

PepsiCo said John Compton, currently chief executive of the North America group, will be the new head of the Americas food division.

Massimo d'Amore, executive vice president of the commercial division of PepsiCo International, will be the chief executive of the new Americas beverage unit, the company said.
