Potlatch Corp., Spokane, Wash., allocated an additional $38 million to Patterson Capital, a domestic fixed-income manager that was already running $23 million for the company’s $650 million defined benefit plan, said Gerald Zuehlke, treasurer. The source of the funding, Dreyfus Investment Advisors — which ran a domestic fixed-income portfolio — was terminated because of poor performance and staff changes, Mr. Zuehlke said. Beth Basilio, spokeswoman for Dreyfus Investment, didn’t return phone calls by press time.
