"It's a big surprise for me, " he said. "As you know, I worked with both Vikram and John Havens for 20 years at Morgan Stanley . This seems like a very abrupt change. Usually a major institution like that announces a change, and it takes place over a period of time. To have it take place instantaneously is quite a shock to the investment community and to me personally."
