Six events should trigger a 401(k) service provider review before your next scheduled one: your provider is acquired or sold, your company merges or is acquired, fees or the fee structure change, service failures repeat, the plan's design or population changes materially, or the people servicing your account turn over.
What they have in common is that each one changes something you relied on when you agreed to the arrangement.
Why Timing Matters Here
None of those events arrives on your review schedule, and none of them looks like a fiduciary matter while it's happening. That's what makes them easy to note and then leave alone.
Prudence is judged on the process behind a decision, so what your record has to show is whether you looked, when you looked, and what you concluded. A review opened three weeks after the event carries a date. A line in next year's minutes saying the change was discussed does not.
What turns these events into a process isn't judgment, it's having somewhere to write down what you did and when. That doesn't require a new system. It requires a brief review of the events your committee already knows how to complete.
How Often Should a 401(k) Plan Go Out to Bid?
There is no required interval. What the rules ask for is a formal review process at reasonable intervals, run to decide whether you continue with your current providers or look for replacements. You set the interval and you defend it.
The harder question is what you actually do when it comes around, because three different things get called a provider review:
- Fee benchmarking. Shows how your costs compare to the market. Fees are evaluated at selection and then monitored to confirm they continue to be reasonable for the services received.
- Request for information. You ask a short list of providers for current pricing and service detail. No bid, no commitment.
- Request for proposal. A full competitive process. Slower and costlier, and the one that puts providers in direct competition for the work.
You already do this with the investment menu. A quick check often, a deeper look now and then.
A schedule tells you when to look. It doesn't tell you what to do when something happens in between.
What Happens When Your 401(k) Recordkeeper Is Acquired?
You didn't select the acquiring firm, so the arrangement you're now in is one you inherited rather than chose. That's why the event matters.
Open a review and work through five items:
- The disclosure. Request the current fee and service disclosure from the acquiring entity rather than relying on the one in your file.
- The contract. Confirm which terms carried over, particularly service standards, termination rights, and conversion costs.
- The service model. Identify who handles your plan now, what they are responsible for, and where escalation goes.
- The fees. Compare the restated schedule against what you were paying and against the market.
- A decision date. Set one at the start. Reviews without a closing date become reviews that never closed.
Confirming whether the information you relied on at hire still holds is a standing part of monitoring. An acquisition is a plain case where it may not.
What Should You Do When 401(k) Fees Go Up?
A fee change is the trigger most likely to reach you in writing with a date on it, because your provider is required to tell you.
A covered service provider must disclose a change to the services, status, compensation, and manner of receipt information it originally gave you as soon as practicable, and no later than 60 days from the date it is informed of the change.
Changes to investment-related information are disclosed at least annually, and an error in what was disclosed is corrected within 30 days of the provider learning of it.
Read what actually changed, since compensation, services, and fiduciary status carry different implications. Benchmark the new number rather than the old one, document the comparison, and record the decision, including a decision to accept the change.
An increase isn't automatically unreasonable.
Fees have to be reasonable for the services received, so an increase paired with expanded services can be defensible.
What is hard to defend is a fee schedule nobody on the committee can explain.
How Do You Document a Provider Review If You Decide to Stay?
A review can properly end with the committee staying where it is. That outcome still needs a record, because a review that produced no change and no documentation is indistinguishable from one that never happened.
Write down six things:
- What triggered the review and the date it opened
- What you compared the current arrangement against
- Who participated and what information they had
- What you concluded and the reasoning behind it
- Anything you asked the provider to change, and the response
- The date the review closed
A written record of the process you followed and the reasons for your conclusion is the point of the exercise, whether you move or stay. It belongs alongside the standing items your committee confirms at every meeting rather than in a separate file nobody opens.
What Your Committee Should Do With This
Judge your provider oversight on two things: whether you have a scheduled review your committee actually runs, and whether you have a defined response for the events that occur between those reviews. The first is straightforward to confirm. The second is the one worth checking for.
It's easy to assume you would act if a provider were acquired or fees moved, but assumption and record are different things, and the gap only shows when someone asks for the file. Working through the last two years event by event, against a structured list, is faster than reconstructing it from memory.
What This Is Really About
None of this is really about providers. It's about whether your oversight leaves a trail.
You can't control whether your recordkeeper gets acquired, whether your fees move, or whether the service team you trusted stays in place. You can control whether each of those events produced a review, a conclusion, and a date. What you can show about provider oversight lives in that record.
The test is simple. If someone asked today how your committee arrived at its current provider arrangement, could you explain it, in order, with dates.
Now Check Your Own Plan
Knowing which events should trigger a review is the easy part. Confirming your plan responded to the ones that occurred is where committees find gaps, and it takes a look back rather than a conversation about policy. Two reasonable ways to start: have someone go through the record with you, or work through it yourself first and see what turns up.
