Jack Calhoun

Gap Inc. incoming Chief Executive Officer Art Peck is overhauling management at the ailing Banana Republic and Gap brands. Jeff Kirwan, 48, will replace Stephen Sunnucks as global president for the Gap chain in December, and Andi Owen, 49, will succeed Jack Calhoun on Jan. 5 as global president for Banana Republic, the retailer's upscale chain. The move marks Peck's first major decision since CEO Glenn Murphy said last month that he will step down in February.
