Oklahoma School Land Trust, Oklahoma City, hired Seneca Capital Management to replace George D. Bjurman as a midcap growth U.S. equity manager for its $990 million trust fund, said Herb Johnson, director of investments. Performance was the reason for the change, he said. Seneca will run $25 million funded from the $20 million terminated Bjurman mandate and $5 million from rebalancing, Mr. Johnson said. Andrew Bjurman, president and CEO for Bjurman, did not return phone calls by press time.
