Ian Chimes, managing director of European distribution with Credit Suisse Asset Management, will also assume responsibility for U.S. sales and marketing, said Wesley McDade, spokesman. Gail S. Landis, managing director, U.S. sales and marketing, is leaving the firm, Mr. McDade said. Ms. Landis referred all inquiries to Mr. McDade, who couldn't provide any specifics about her next move. Also, Mark Burgess, who joined CSAM in July as managing director, global co-head of equities, was named global head of equities, with the departure of fellow co-head Greg Sawers, who also led CSAM's U.S. equities operations. Mr. Sawers' departure had been planned for some time, said Mr. McDade; he is leaving to "take some time off," Mr. McDade said. Steve Kaszynski, managing director, head of U.S. value equities, will also assume Mr. Sawers' responsibilities as head of U.S. equities, while Bob Rescoe, a director and portfolio manager, will also become head of U.S. equity research, Mr. McDade said.
