David Seto joined Weiss Peck & Greer as a senior vice president and fixed-income portfolio manager, said Daniel S. Vandivort, co-head of fixed income at the firm, a unit of Robeco Investment Management. Mr. Seto will oversee structured securities and international fixed-income investment portfolios. Mr. Seto will report to Wen-Ching Wang, managing director and head of Weiss Peck & Greer's government and structured securities team. The firm added the position in part because the structured securities element "is growing pretty rapidly" and "activities in the international arena are also expanding," Mr. Vandivort said. Mr. Seto was a vice president and portfolio manager at Neuberger Berman, where he managed structured securities for the fixed-income group. He was also co-manager of the international fixed-income group. Hannah Burns, a Neuberger Berman spokeswoman, did not return a call by press time requesting information about a replacement.
