Information technology is the single biggest source of risk for companies today, according to a survey of top executives in the U.S., U.K., Japan, Germany, France and Italy. The annual Swiss Re Corporate Risk Survey found that executives rank IT at 6.00 on a risk scale of 0 to 10, where 10 indicates “extreme concern.” Coming in second was foreign trade, at 5.29, followed by corporate governance, at 5.22. IT was the only risk source that was rated as one of the top three risks by executives in all six of the countries. It came in at number one for U.S., U.K. and Japanese managers as well as for managers in the manufacturing and financial industries. Concerns about computer-related risk continue to increase, moreover, with 60% of executives saying that their fears about IT are greater today than they were a year ago.
