MDU Resources Group, Bismarck, N.D., increased its small-cap U.S. equity and international equity exposures to 15% each of total assets from 10% and is considering a search for an additional international equity manager following a recent asset-liability study of its $250 million defined benefit plan, said Warren Robinson, CFO and treasurer. Lazard Asset Management and J.&W. Seligman, small-cap U.S. equity managers running $12.5 million apiece, will each receive a 5% increase, he said. Templeton International, which manages $25 million in international equities for the fund, could see a 5% increase if an additional international equity manager is not hired. Portfolio styles were not available. No timetable was set for a decision.
