Vulcan Materials Co., Birmingham, Ala., is considering a search for an index manager for its $475 million defined benefit plan, said J. Wayne Houston, investment officer. Barclays Global Investors currently runs one index fund and State Street Global Advisors runs two for the plan, said Mr. Houston, who refused to divulge portfolio styles, sizes and the reason for the search. If a search is launched, both incumbents will be considered, he added. No decision has yet been made about whether an index fund will be added or a current index manager will be replaced. A decision is expected next month.
