Andrew Williams advises those employers which maintain a 401(k) or any other retirement plan to take a look at their internal practices and administrative procedures. In-house fiduciaries are charged under ERISA with a duty to “monitor” the activities of each plan service provider.  This entails the ongoing review of the quality, sufficiency and cost of services provided to the plan and its participants. No matter how comfortable an employer’s relationship with its plan service providers may be, it is the responsibility of the employer/plan administrator and retirement plan committee members to assure that plan participants are receiving necessary and appropriate services at a cost that is reasonable.
