ERISA 3(38) Fiduciaries

ERISA 3(38) defines “investment managers” and allows named fiduciaries to formally appoint them. When properly appointed and monitored, an investment manager assumes discretionary authority over selecting, monitoring, and replacing plan investments, and the trustee is relieved of liability for the manager’s actions. Investment managers control the acquisition and disposition of plan assets, select brokers, and must act prudently in all decisions.

Only Registered Investment Advisors, banks, or qualified insurance companies may serve as 3(38) investment managers, and they must acknowledge their fiduciary status in writing. Improper appointment removes liability protection for the plan sponsor. Even with a valid appointment, sponsors retain an ongoing duty to monitor the investment manager’s performance and ensure fees remain reasonable.

Investment managers may manage all or part of a plan’s assets. Their duties include investment selection, monitoring, diversification, liquidity management, and alignment with the plan’s objectives. Defined benefit plans require additional consideration of participant demographics and cash‑flow needs, while participant‑directed plans reduce—but do not eliminate—fiduciary responsibilities. Investment managers often select plan investment menus and may operate plan‑specific investment funds.

The Pension Protection Act expanded fiduciary considerations, particularly regarding Qualified Default Investment Alternatives (QDIAs). QDIAs apply when participants fail to make investment elections, including in automatic enrollment plans or when elections are missing or invalid. QDIA relief parallels ERISA 404(c) protection but remains limited and conditional.

Only certain investment types qualify as QDIAs, including target‑date funds, balanced funds, and managed accounts. Non‑mutual‑fund QDIAs must be managed by qualified entities, including 3(38) investment managers. Brokers generally cannot serve as QDIA managers. Plan sponsors may manage QDIAs themselves, but advisers assisting sponsor‑managed QDIAs become fiduciaries.

Selecting and managing QDIAs requires an objective, analytical process. Fiduciaries must evaluate costs, ensure transferability out of QDIAs, provide required participant notices, assess investment theory, and confirm proper diversification. Ultimately, management structure significantly affects fiduciary exposure, and fiduciary relief programs offer only limited protection. Meaningful fiduciary responsibility rests on conduct, not promises or labels.

ERISA imposes some of the highest standards of care in the legal system, and fiduciary responsibility ultimately turns on conduct rather than titles, marketing language, or contractual disclaimers. While engaging advisors, investment managers, and fiduciary programs can significantly assist plan sponsors in meeting their obligations, these arrangements do not eliminate the need for careful oversight, informed decision‑making, and ongoing monitoring. The distinction between 3(21) and 3(38) fiduciary roles is particularly important, as it determines where discretion lies and how investment‑related liability is allocated. Similarly, fiduciary relief programs and QDIA structures offer only limited protection and must be evaluated with a clear understanding of what duties remain with the sponsor. In the end, meaningful fiduciary protection is achieved not through promises or labels, but through prudent processes, documented decision‑making, and a disciplined commitment to acting solely in the best interests of plan participants.
