Besides royalty payments from new stores, the parent company also enjoyed significant profits by requiring franchisees to purchase mix and doughnut-making equipment from the parent's Krispy Kreme Manufacturing and Distribution (KKM&D) division. KKM&D earned $152.7 million in 2003, which made up 31 percent of sales, with a reported operating margin of 20 percent or higher, but these mark-ups were largely at the expense of its franchisees. By comparison, rival chain Dunkin' Donuts generally avoids selling equipment or materials to its franchisees which "keeps company and franchisee interests aligned", as well as having a royalty stream based on same-store sales.
