Carpenter Technology Corp., Reading, Pa., with $950 million in defined benefit plan assets, hired SEI Asset Management to manage between $100 million and $125 million using SEIs total outsourcing program for core large-cap value and growth. SEI will assume manager selection and management responsibility for the core equity account in about two weeks, said Robert Dixon, Carpenter Technology vice president and treasurer. The change was precipitated by UBS Brinsons termination of a domestic indexed strategy about three months ago, Mr. Dixon said. The company moved the indexed assets to J.P. Morgan, which had been managing a domestic core equity product for Carpenter Technology. The assets from the core strategy will provide the funding for SEI, Mr. Dixon said.
