Ohio Police & Fire Pension Fund, Columbus, plans to search before the end of the third quarter for a manager to run $90 million in active domestic large-cap growth equities. Current manager AllianceBernstein is being terminated due to pending civil litigation against parent Alliance Capital resulting from the firms investments in Enron Corp., said Amy Hoiland, communications manager for the $8.2 billion plan. No timeline has been set for issuing an RFP or making a selection. John Meyers, an Alliance spokesman, declined to comment. Wilshire Associates will assist.
