CINCINNATI -- Procter & Gamble recently announced new executive and business unit structures. Susan Arnold and Robert McDonald were promoted to vice chairs of global beauty care and global operations, respectively, effective July 1. Prior to her appointment, Arnold was president of global personal beauty care and global feminine care. McDonald was president of global fabric and home care. The responsibilities of the two existing chairs, Bruce Byrnes and R. Kerry Clark, will be shifted. Byrnes, who was vice chair overseeing global beauty and feminine care, and global health care, will assume the title of vice chair for global household care. Clark will become the vice chair in charge of global health, baby and family care; his former role was vice chair supervising global market development and business operations. The reshuffling of responsibilities reflects the growing role of Procter & Gamble's health and beauty products, according to media reports, as well as broadening the pool of successors for Chief Executive A.G. Lafley's position. The company also announced the realignment of its business units, also effective July 1, into global beauty care; global health, baby and family care; and global household care.
