Georgia-Pacific Corp., Atlanta, will reallocate Global Asset Managements $37 million international equity portfolio at the end of October. The termination was related to performance and the departure of portfolio manager John Horseman, said John Stettler, vice president-benefit investments for the $2.4 billion defined benefit plan. Capital Guardian will receive $10 million to manage in its existing $26 million international equity portfolio. The remaining $27 million of the GAM portfolio will be placed in a stock and bond futures liquidity account managed by INVESCO, which generally has totalled between $20 million and $25 million in any given quarter, Mr. Stettler said. Representatives from Global Asset Management did not return phone calls for comment by press time.
