PepsiCo is moving its senior vice president of investor relations to work on the company's proposed purchase of Pepsi Bottling Group and PepsiAmericas.

The company confirmed today (2 June) that Mike Nathenson will work more closely with CFO Richard Goodman and the PepsiCo senior management team on the transaction.

PepsiCo has seen its offer, made in April, to buy the outstanding shares that it does not yet own in the two companies turned down by both PBG and PepsiAmericas.

Nathenson had previously served as vice president of PepsiCo financial planning & analysis, leading the company's annual operating planning, strategic planning, capital expenditure planning, forecasting and business planning processes. Before that, he held a variety of financial positions at Frito-Lay North America, before becoming CFO of PepsiCo's Australia snacks business.

He will be replaced by Lynn Tyson, who rejoins PepsiCo after nine years at Dell.

"We are very pleased to welcome Lynn back to the PepsiCo family," said Goodman. "Her more than 20-year track record as a leader began at PepsiCo, and we are confident these leadership skills and industry experience will make her a trusted resource for our shareholders."

Tyson will be based at the company's headquarters in Purchase, N.Y.
