The Plan Sponsor's Fiduciary Checklist

If you exercise discretion over an ERISA-covered retirement plan, you may be personally responsible for the decisions you make. The strongest protection is not a perfect investment record. It is a prudent process that is consistently followed and clearly documented.

The short answer

ERISA does not judge a fiduciary solely on a plan's investment returns. It asks whether the fiduciary acted loyally and prudently under the circumstances, followed a reasonable process, and can show what was considered and why a decision was made. That distinction matters because committee minutes, fee comparisons, investment reviews, and service-provider evaluations can become the evidentiary record years later.

What the statute actually says

ERISA Section 404(a)(1) requires a fiduciary to act solely in the interest of participants and beneficiaries, for the exclusive purpose of providing benefits and defraying reasonable plan expenses. Its prudence standard requires a fiduciary to act with the care, skill, prudence, and diligence that a prudent person familiar with such matters would use under the circumstances then prevailing.

Two points follow. First, a decision is judged against what was reasonably knowable when it was made, not solely by what happened afterward. Underperformance by itself is not necessarily a breach, although sustained underperformance may raise questions about whether the monitoring process was adequate. Second, the standard is not reduced because a committee member lacks investment or plan expertise. When the necessary expertise is not available internally, prudence generally requires obtaining qualified assistance.

The 404(c) misunderstanding

Many sponsors assume that participant-directed accounts insulate the committee from investment responsibility. Section 404(c) may relieve a fiduciary of responsibility for losses resulting from a participant's own choices among the options offered. It does not relieve the fiduciary of responsibility for selecting and monitoring those options in the first place.

The duty to monitor is ongoing and separate from the duty of prudent initial selection. No universal review schedule applies to every plan, which makes the committee's documented rationale for its cadence and review standards especially important.

Why the written record matters more

In Cunningham v. Cornell University, the Supreme Court made certain prohibited-transaction claims easier to plead without requiring plaintiffs to address statutory exemptions at the outset. The practical effect is that more disputes may move beyond an early motion to dismiss and into discovery, where the question becomes what the plan's records show about the necessity of services, the reasonableness of compensation, and the committee's deliberative process.

Plan fiduciary litigation should be neither dismissed as remote nor treated as inevitable. The durable lesson is simpler: a committee should assume that someone who was not in the room may one day evaluate its decisions from the written record alone.

Use comparisons that can withstand scrutiny

Fee and investment reviews are only as useful as the comparisons behind them. Recordkeeping and administrative fees should be benchmarked against plans with reasonably similar assets, participant counts, services, and complexity. Investments should be compared with alternatives that have similar mandates, strategies, and risk profiles. The file should show not only the result of the comparison, but why the committee considered the comparison meaningful.

The fiduciary checklist

No statute prescribes one required format for a fiduciary file. That does not make the underlying work optional. A defensible process typically includes the following:

1. Identify the fiduciaries. Maintain a clear record of the named fiduciaries, committee members, and others who exercise discretion over the plan. Make sure each person understands the role and the duties that come with it.
2. Establish a committee charter. Use a written charter that defines authority, membership, responsibilities, meeting cadence, and decision-making procedures.
3. Adopt and follow an investment policy statement. The IPS should describe how investments are selected, monitored, placed on watch, and replaced. A policy that is routinely ignored may be more damaging than helpful unless departures are explained and documented.
4. Document deliberation, not just decisions. Minutes should record the information reviewed, the questions considered, the advice received, and the reasons for the committee's decision. A list of motions and votes rarely tells the full story.
5. Monitor the investment menu consistently. Review each option against the plan's stated criteria on a regular cycle. The goal is not to chase short-term performance, but to apply consistent standards and act when those standards are no longer met.
6. Benchmark fees and services. Compare recordkeeping, administration, investment expenses, and adviser compensation with reasonably comparable plans. Reasonable does not necessarily mean cheapest; it means the committee understands what is being paid, what the plan receives, and why the arrangement remains appropriate.
7. Review required fee disclosures. Collect covered service-provider disclosures under Section 408(b)(2) and participant fee disclosures under Section 404a-5. The record should show that the committee reviewed them rather than merely filed them.
8. Oversee service providers. Periodically evaluate the quality, scope, cost, and operational performance of recordkeepers, administrators, payroll connections, advisers, trustees, and other providers. Document when an arrangement was re-bid, renegotiated, or retained and why.
9. Document cybersecurity diligence. Maintain a record of the committee's review of the cybersecurity practices of providers that handle participant data or plan assets, including how identified concerns were addressed.
10. Confirm bonding and insurance. Maintain the fidelity bond required for people who handle plan funds and understand that fiduciary liability insurance is a separate product. Confirm who is insured, what is excluded, and whether the policy permits recourse against a breaching fiduciary when plan assets pay the premium.
11. Keep plan documents current. Maintain a current, executed written plan document and a reliable process for tracking amendments, operational changes, disclosure obligations, and other applicable requirements with the plan's administrator and ERISA counsel.

If you sit on a committee

Nothing here is legal advice, and the questions that matter most for a particular plan belong with ERISA counsel. TAGStone provides fiduciary investment services to 401(k), 403(b), defined benefit, and deferred compensation plans, including investment policy development, menu monitoring, fee benchmarking, provider oversight, and participant education. Depending on the engagement, we serve in either a 3(21) advisory or 3(38) discretionary fiduciary capacity. Even when serving as a 3(38) investment manager, we typically consult with the plan sponsor before making changes to the investment menu.

A strong fiduciary process should be clear in the record, not just understood by the people in the room. TAGStone helps plan sponsors build and document the investment selection, monitoring, and benchmarking process. An independent review can show what is working, where the record is incomplete, and what should be addressed first.
