Nomura Securities International Inc., a Japanese asset management company, announced that it has promoted Dean Chamberlain and Sotaro Kato to run its fixed-income investment portfolio management business.

They succeeded Hirofumi Misawa, who will oversee the integration of Lehman Brothers' bond business in Asia, Nomura Securities said Monday.

Last month Nomura agreed to buy Lehman's European, Middle East, and Asia operations after the U.S. investment bank filed for bankruptcy protection.

Mr. Kato and Mr. Chamberlain are based in New York. They will report to Shigesuke Kashiwagi, Nomura Securities' chairman, president, and chief executive officer.

Mr. Chamberlain joined Nomura in April 2005 and had been deputy head of fixed income. Before joining Nomura he had managed the Midwest distribution of mortgage-related and structured products at Banc of America Securities.

Mr. Kato joined Nomura's U.S. investment banking arm as co-deputy head of fixed income in August. Before that he had been the head of the "macro-risk" derivative business at Nomura Securities Co. Ltd. in Japan.
