Michael Kors’ revenue rose 17.8 percent in the fourth quarter, slowing sharply from the growth of 29.9-74.4 percent it posted for the past 13 quarters. Same-store sales in North America fell 6.7 percent. Lower tourist traffic in U.S. Northeast and Southeast, weak sales in its watches business and shipping delays due to disruptions at West Coast ports hurt sales in North America, Chief Financial Officer Joe Parsons said.
