401(h) Plan Fiduciary Duties: A Plain-English Overview
Plan fiduciaries owe the same duties for 401(h) assets as for the retirement portion. Here's how those duties show up in practice.
Key takeaways
- Prudence applies to investment, vendor, and benefit-administration decisions.
- Loyalty means acting in participants' interests, not the sponsor's convenience.
- Documents must be followed — discretion has limits.
- Fiduciary process matters as much as outcome.
Prudence in practice
Investment, vendor, and benefit-administration decisions are fiduciary acts. Documented prudent process — minutes, analyses, comparable considered — is the durable defense.
Loyalty
Fiduciaries act in the interest of participants and beneficiaries. Sponsor convenience is not a justification.
Follow the document
Discretion lives within plan-document boundaries. Operating against the document is operationally and legally fragile.
