ERISA 3(21) & 3(38) Fiduciary Capabilities

Selecting the appropriate fiduciary structure is a critical governance decision for 401(k) plan sponsors. Under the Employee Retirement Income Security Act of 1974 (ERISA), plan sponsors may engage investment professionals in different fiduciary capacities depending on their oversight preferences, internal expertise, and risk management objectives.

Fiduciary Capital Management LLC provides both ERISA §3(21) and ERISA §3(38) fiduciary services to align with the governance needs of plan sponsors and investment committees.
