Bank One hired Fidelity to provide record keeping, trust services and some mutual funds for a new 401(k) plan program called Pathways to Retirement. Bank One will handle education, communications and distribution. The platform includes mutual funds managed by both Bank One and Fidelity, as well as by other outside managers. Fidelity is Bank Ones third external services provider, said Julie Crothers, a Bank One spokeswoman. The others are Scudder and INVESCO.
