US chewing gum maker Wrigley has announced that it has appointed chief financial officer Ron Waters to the new role of chief operating officer.

The move follows the decision by Gary McCullough, senior vice president of Wrigley’s Americas business, to leave the company, effective 12 December.

As a result of the changes, Wrigley has also appointed Reuben Gamoran as its new CFO. Gamoran currently holds the position of vice president and controller.
