ERISA Section 3(16) Administrator
A 3(16) Administrator is the person or entity “so designated” in the plan document. The employer is the default Plan Administrator if none is designated. The Plan Administrator is basically responsible for any fiduciary responsibility not assumed by the ERISA section 403(a) Trustee.
ERISA Section 402(a) Named Fiduciary
A 402(a) Named Fiduciary is formally designated in the plan document as the individual or entity with ultimate authority over the management and administration of the retirement plan. In most cases, this role is fulfilled by the ERISA Section 3(16) Plan Administrator.
ERISA Section 3(38) Investment Fiduciary
A 3(38) Investment Manager is a fiduciary under ERISA, responsible for selecting, managing, monitoring, and benchmarking a retirement plan's investments. In some plans, they also have discretionary authority to direct fund investments, except in participant-directed plans.
