Northern Illinois Gas, Aurora, will search for a full-retainer consultant if it decides to conduct an asset-liability study for its $467 million defined benefit plan, said Larry Lackey, spokesman for Northern. Callan Associates conducts performance reviews for the fund, but a full-retainer consultant would be necessary to conduct the study, said Mr. Lackey. No timetable was set for a decision.
