Kellogg announced several key executive changes today, including the promotion of Mark Baynes to vp and global CMO.

Previously Kellogg's global CMO, Baynes is now responsible for the packaged goods giant's "brand-building initiatives" and ensuring worldwide marketing efforts align with Kellogg's long-term goals for growth, per the company.

Other management changes include the departure of Jeff Montie, currently evp of Kellogg and president of Kellogg International, global innovation, and marketing and sales.

"Jeff has been a valued member of our global leadership team. His marketing talents and management abilities greatly benefited Kellogg throughout his more than 20-year career with the company," David Mackay, Kellogg's president and CEO, said in a statement. The vacant position will be filled in the near future, per Kellogg, Battle Creek, Mich.

Brad Davidson, who previously oversaw Kellogg's snacks division in the U.S. and Canada, is now svp and president of Kellogg North America. Davidson joined Kellogg in 1984 and has been in his current post for five years. He is credited with growing Kellogg's snacks business into one of the company's largest operating units.

Paul Norman, svp of Kellogg and president of U.S. Morning Foods, has been elevated to svp and president of Kellogg International. An 11-year veteran of the company, Norman has served in leadership roles in Kellogg's Canada, Mexico and U.K. businesses. He also helped grow the company's U.S. Morning Foods, Kashi and Frozen Foods brands during a "cost-inflationary environment," Mackay said. In his new role, Norman will be responsible for Kellogg's growth in emerging new markets, the company said.

Finally, John Bryant, evp, CFO and president of Kellogg North America, is now COO; Juan Pablo Villalobos, svp and president of Kellogg Latin America, is now svp and president of U.S. Morning Foods; and Todd Penegor, CFO of Kellogg Europe, is now vp of Kellogg and president of Kellogg U.S. Snacks. All appointments are effective immediately.

"These new assignments demonstrate the depth of our management bench and are part of our continuing commitment to growing talent from within the organization," Mackay said. "The strength of our leadership team gives us great confidence in our ability to continue driving sustainable performance in a highly challenging environment."

Kellogg spent $595 million on advertising last year (excluding online), per Nielsen Monitor-Plus. With $12 billion in sales last year, Kellogg's signature brands include Pop-Tarts, Eggo, Rice Krispies and Nutri-Grain. The company's products are sold in 180 countries.
