Most committees should review their 401(k) investment lineup on two cadences: a quarterly check that the funds still meet the plan's criteria, and a deeper annual review of whether those criteria still make sense.
ERISA doesn't set a review frequency, it requires a prudent, ongoing process, so what matters is showing that oversight continued rather than hitting a specific date.
Monitoring and reviewing are different jobs: the quarterly check applies your existing standards, while the annual review steps back and asks whether those standards, the default investment, and the fees still fit.
Committees that do the annual review but skip the quarterly checks tend to fall behind, because the months in between go undocumented and there's nothing showing oversight continued.
The value of any review is only captured when it's recorded, so consistent minutes and a clear cadence are what turn good discussions into something the committee can rely on later.
Most committees should review their 401(k) investment lineup every quarter, with a deeper review once a year. The quarterly check confirms the funds you hold still meet your criteria. The annual review steps back and asks whether those criteria still make sense.
Committees that do the annual review but skip the quarterly checks are the ones that fall behind.
Why Getting the Timing Right Matters.
Of all the fiduciary duties, investment monitoring is the one most likely to get examined and the one committees document worst.
ERISA does not tell you how often to review. It just says the process has to be careful and ongoing.
So if a regulator asks or a fee claim comes up, the question is not whether your funds beat the market. It is whether you can show you were paying attention the whole time.
Review only once a year and the months in between leave no trace. Check in every quarter but never step back, and you can end up carefully following standards that no longer fit.
Committees rarely struggle with whether monitoring matters.
They struggle with keeping the cadence running and holding a record that each step happened. Seeing the full year of oversight in one place is what makes that easier.
Committee Checklist
Investment Lineup Review Checklist
A one-page reference that separates quarterly monitoring from the annual review, so your committee can run each on schedule and document it as you go.
The rule is a process, not a calendar. ERISA asks for prudent, continuous monitoring, which most plans meet with two layers:
Quarterly monitoring. Check the funds you hold against your stated criteria, and update the watch list.
Annual review. Step back and confirm the criteria, default investment, and fees themselves still fit.
This holds for plans of any size.
Larger plans often benchmark fees more deeply, but the quarterly rhythm matters just as much for a small plan.
In fact, a small committee needs the fixed schedule more, because reviews are the first thing to slip when the plan is no one’s full-time job.
Where Fiduciary Risk Develops: Monitoring Versus Reviewing
The two words get used interchangeably, and that is where some committees get into trouble.
Monitoring is the quarterly check. It asks one simple question: are the funds we hold still meeting the standards we set? If one slips, it goes on the watch list.
Reviewing is the annual step back. It asks a bigger question: do the standards themselves still make sense, along with the default investment, the fees, and whether the menu fits the people actually in the plan? The review can change the rules. Monitoring just applies them.
A steady quarterly committee review is what keeps monitoring from slipping between annual meetings, and having that record quarter after quarter is what shows the oversight was real.
What Each Review Actually Covers
The quarterly check is meant to be efficient. With the policy and a current fund scorecard in hand, it is one agenda item, not a meeting of its own:
Performance against criteria. Measure each fund against its IPS benchmark and peer group.
Watch list. Add or remove funds, with a recorded reason for each.
Default investment. Confirm the QDIA is performing as expected.
Open flags. Note anything the recordkeeper or advisor raised since the last meeting.
The annual review goes deeper and builds on that work rather than repeating it:
Reaffirm the IPS. Confirm the benchmarks, criteria, and watch-list rules still fit.
Evaluate the default in full. Weigh the target-date glidepath and demographic fit, not recent return alone.
Benchmark fees. Test investment and, where relevant, recordkeeping fees for reasonableness. This is the duty most often litigated.
Confirm the menu fits. Check it still matches the participants you actually have, in number and sophistication.
None of it counts unless you write it down.
Good committee meeting minutes
turn a solid discussion into something you can point to later, which is the first thing anyone looking at the plan will ask to see.
What This Means for Your Committee
Measure your process by whether you run it consistently and write it down, not by whether the funds had a good year.
The quarterly check catches small problems before they grow, and the annual review makes sure the standards you hold funds to still make sense.
A committee that does both and keeps a record can show its oversight never stopped, and that is what actually gets looked at.
The harder question is about your own plan: is this actually happening, or has the committee just assumed it is?
Reviews slip and decisions go unwritten without anyone meaning to let it happen, and that kind of gap is a lot easier to spot against a checklist than to piece back together from memory.
The Broader Governance View
Step back far enough and this is not really about picking funds.
It is about being able to show your work. A committee cannot control how a fund does in a given quarter, and no one expects it to. What it can control is whether it followed a steady process and kept the documentation.
Here is a good test: if someone asked why a particular fund is in your plan, could you point to when you reviewed it and what you decided?
From Knowing to Confirming
Knowing that monitoring matters is one thing.
Confirming it actually happens inside your own plan, every quarter, with a record you could show later, is another.
Most committees are somewhere in between: the intent is there, but the schedule has drifted or the documentation is thinner than anyone realized.
The way to close that gap is to look honestly at how your reviews run today and where they quietly fall short. That usually happens one of two ways, and neither takes much time.
You can bring in a second set of eyes to look at your current cadence with you, or you can work through it yourself first and see what the exercise turns up.
If You Want a Clearer View of Your Plan
If it would help to confirm your cadence and documentation would hold up, a brief review can focus specifically on your investment oversight: how your quarterly and annual reviews run, how decisions are recorded, and where the process would show gaps.
If your committee would rather start on its own, the Investment Lineup Checklist below gives you a structured way to run the reviews and document each step, at your own pace, before any outside conversation.
Committee Checklist
Investment Lineup Review Checklist
A one-page reference that separates quarterly monitoring from the annual review, so your committee can run each on schedule and document it as you go.
Most plans use two layers: quarterly monitoring of funds against the investment policy statement, and a deeper annual review of the policy statement, default investment, and fees. ERISA sets no required frequency, only a prudent, ongoing process.
No specific schedule is mandated, only prudent, continuous monitoring. A quarterly cadence is a common way to show monitoring was ongoing. Separately, 404(c) requires that participants be able to change their own investments at least quarterly, a different rule.
Monitoring is the quarterly check of whether existing funds still meet stated criteria. Reviewing is the deeper annual evaluation of whether the criteria, default investment, fees, and menu are still appropriate. Monitoring applies the rules, reviewing decides whether they still fit.
The funds reviewed, criteria applied, watch-list changes with reasons, retain-or-replace decisions, and follow-up actions. This is what demonstrates a prudent process during a Department of Labor inquiry or audit.

If a retirement plan committee does not meet regularly or document its decisions, it can be difficult to prove that fiduciary oversight actually occurred during a Department of Labor inquiry or audit.
Most 401(k) committees meet every quarter and assume that's enough. The strongest committees review the same four things each time: investments, service providers, compliance, and follow-through.
