Why Benchmarking Is a Fiduciary Obligation, Not a Shopping Exercise
ERISA 404(a)(1) requires fiduciaries to act prudently and to defray reasonable plan expenses. "Reasonable" is a comparative word — it cannot be evaluated without comparison. And ERISA 408(b)(2) only exempts a service arrangement from the prohibited-transaction rules if the services are necessary and the compensation is reasonable, which the responsible fiduciary must affirmatively determine using the provider's disclosures.
That is the whole legal basis of benchmarking: you cannot conclude fees are reasonable if you never measured them. In the wave of excessive-fee litigation, the recurring fact pattern is not that a plan paid too much — it is that no fiduciary could produce evidence of ever having checked.
What a Real Benchmarking Review Measures
| Layer | What we measure | What it exposes |
|---|---|---|
| Investment expense | Fund-by-fund expense ratios, share class actually held vs. available, revenue sharing | Retail share classes in a plan that qualifies for institutional pricing |
| Recordkeeping & administration | Per-participant and asset-based fees, base fees, transaction and event charges | Asset-based pricing that grew with the plan while the work did not |
| Advisory / investment fiduciary | Advisor compensation, service scope, fiduciary status (3(21) vs. 3(38)) | Fees paid for a fiduciary service the plan never actually received |
| Fee allocation | Who pays: plan assets, forfeitures, employer, per-head vs. pro-rata | Small balances subsidizing large ones, or the reverse |
| Plan design & outcomes | Eligibility, match formula, auto-enrollment, participation and deferral rates | Cost being paid without the participation the design should produce |
| Service delivery | Testing timeliness, notice delivery, 5500 accuracy, issue resolution | What the fee is actually buying in practice |
The Data We Use
Your 408(b)(2) disclosures
The provider's own required fee disclosure — the document a fiduciary is supposed to be evaluating.
Form 5500, Schedules C and H
Reported service-provider compensation and trust activity, which is public and comparable across plans of your size.
Peer sets by plan size
Comparisons built on participant count and asset level, because per-participant economics change dramatically with scale.
Fund-level expense data
Actual holdings, share classes and available alternatives within the same fund family.
Your participant data
Participation, deferral rates, balances and outcomes — the return side of the cost question.
Written conclusions
Findings, rationale, and recommended actions, dated and retained in the fiduciary file.
Where Plan Sponsors Get Hurt
Filing the 408(b)(2) disclosure unread. The exemption depends on the fiduciary's determination that compensation is reasonable, and that determination has to happen.
Accepting a provider's own "benchmark." A comparison produced by the party being compared is not independent evidence.
Benchmarking once, years ago. Prudence is ongoing. Asset-based fees rise automatically as balances grow.
Ignoring revenue sharing. Indirect compensation is still plan compensation and must be identified and reasonable.
No documentation of the decision. Deciding to keep a provider is a fiduciary decision. Undocumented, it is indistinguishable from inattention.
What You Get
- A written benchmarking report showing each fee layer against a size-appropriate peer set.
- Specific, prioritized actions — share-class changes, fee renegotiation, allocation fixes, design changes.
- Documentation formatted to sit in the fiduciary file as evidence of a prudent process.
- An independent view: Admin316 does not sell investments or recordkeeping, so there is no product on the other side of the recommendation.
How Plan Fees Are Actually Charged
| Structure | How it is billed | What to watch |
|---|---|---|
| Asset-based (bps) | A percentage of plan assets | Cost rises automatically with market gains and contributions even when the work does not change |
| Per-participant | A flat amount per participant or per account | Whether terminated participants with balances are still being billed |
| Base plus transactional | Flat base fee plus charges per event | Loan, distribution, QDRO and amendment fees that never appear in a quoted rate |
| Revenue sharing | Embedded in fund expenses and paid to the recordkeeper | Whether it is disclosed, reasonable, and credited back to participants |
| Wrap or platform fee | Added inside insurance separate accounts or bundled products | Total participant cost that a fund expense ratio alone will not reveal |
| Paid by the employer | Invoiced to the company instead of the plan | Generally the cleanest structure; confirm which expenses are settlor expenses |
Reading Your Form 5500 Like an Examiner
Schedule C
Direct and indirect compensation reported for each service provider. This is where undisclosed revenue sharing tends to become visible.
Schedule H
Trust-level income, expenses and asset detail. Administrative expenses paid from plan assets show up here.
Schedule A
Insurance contract fees and commissions, which sponsors on bundled platforms routinely do not know they pay.
Line 4a and 4l
The Form 5500 questions that flag late deferral deposits and delinquent participant contributions — a common DOL selection trigger.
Participant counts
Drives the large-plan audit requirement and the per-participant economics of any fee comparison.
Filing history
Late or amended filings tell their own story about administrative control.
Benchmarking More Than Price
Service level. Testing delivered on time, notices delivered with proof, accurate filings, questions resolved without escalation. A cheap provider that generates corrections is not cheap.
Fiduciary status received. If you are paying for fiduciary services, the agreement should acknowledge the specific ERISA section. Paying fiduciary-level fees for non-fiduciary service is a finding waiting to be made.
Participant outcomes. Participation, average deferral rate, auto-enrollment and escalation adoption, and how many eligible employees remain outside the plan.
Design efficiency. A safe harbor or auto-enrollment design can eliminate recurring testing failures and their correction costs entirely.
Who This Fits
- Plans that have never been benchmarked, or not in the last three years.
- Plans that grew substantially while an asset-based fee schedule stayed unchanged.
- Sponsors who want documented evidence of fee reasonableness in the fiduciary file before anyone asks for it.
- Committees preparing to renegotiate with an incumbent provider and needing real comparative data to do it.
Where It Falls Short
- Benchmarking documents and informs a decision; it does not make the decision or implement it.
- If administration is the actual problem, cheaper pricing will not fix operational failures — that is a 3(16) issue.
Frequently Asked Questions
How often should a plan be benchmarked?
There is no statutory interval, but ERISA's duty of prudence is ongoing and asset-based fees change as the plan grows. A documented review at least every one to three years, and any time providers, pricing or plan size change materially, is a defensible cadence.
Isn't benchmarking just a way to sell us a new provider?
It should not be. Admin316 does not sell recordkeeping or investment products. Many reviews conclude that the current provider is reasonably priced, and that conclusion documented in writing is exactly what a fiduciary needs.
What documents do you need from us?
The plan document and adoption agreement, the most recent 408(b)(2) fee disclosure, the last two Form 5500 filings with schedules, a current fund lineup with share classes, the recordkeeper fee schedule, and a participant census.
Does benchmarking prove our fees are reasonable?
Benchmarking produces the evidence a fiduciary uses to reach and document that conclusion. Reasonableness is the fiduciary's determination, based on the services received and comparable market pricing.
What if the review finds we have been overpaying?
You address it prospectively: share-class corrections, renegotiated pricing, a changed fee allocation, or a provider change, with the analysis and decision documented. Acting on findings is what converts a review into fiduciary protection.
Can plan expenses be paid from plan assets?
Reasonable expenses of administering the plan generally can be paid from plan assets. Settlor expenses that benefit the employer, such as designing or deciding to establish or terminate a plan, generally cannot. The distinction should be documented.
Are the lowest fees always the prudent choice?
No. ERISA requires reasonable fees for the services received, not the cheapest available. The documented comparison of cost against services is what satisfies the duty.
How long does a benchmarking review take?
Typically a few weeks once documents are provided, most of which is waiting on provider disclosures and fund data rather than analysis.
Will you tell us to change providers?
Only if the data supports it. We do not sell recordkeeping or investments, so a written conclusion that your current arrangement is reasonable is an equally useful outcome.
Educational information only. Fiduciary status, plan operations and correction options depend on your plan document, service agreements and specific facts. Nothing here is legal, tax, investment or actuarial advice, and reading it does not create a fiduciary or client relationship.
