The summary plan description (SPD) is the single document ERISA requires you to hand every participant, and the summary of material modifications (SMM) is how you keep that document honest after you change the plan.
The SPD is a fiduciary disclosure, not a brochure
That distinction is exactly where sponsors get hurt. If the SPD describes a match formula, an eligibility rule, or a vesting schedule that differs from the plan document, you now have two competing statements about the same benefit — and a participant who relied on the summary.
How SPD duties go wrong in real plans
- The plan was amended two or three times and the SPD still reflects the original design.
- The SPD was emailed once at rollout and never given to anyone hired since.
- Nobody can prove distribution — no distribution list, no date, no method.
- The SPD was posted on an intranet page and treated as “delivered” without meeting electronic disclosure conditions.
- Terminated participants with a remaining balance dropped off the distribution list.
What the SPD has to actually tell participants
The SPD must describe the plan as it operates, in language an average participant can understand. At minimum, a sponsor reviewing a draft should be able to find:
1. Identification of the plan and the people responsible
Plan name, plan number, employer name and EIN, the plan administrator, the trustee, and the agent for service of legal process.
2. Eligibility and entry
Who is covered, what service or age requirements apply, which classes are excluded, and when an eligible employee actually enters the plan.
3. Contributions and the compensation definition
Deferral limits described in general terms, the employer match or nonelective formula, and — critically — the definition of compensation used to calculate contributions. If your SPD says “total pay” and your document excludes bonuses, you have a problem waiting for a bonus cycle.
4. Vesting
The vesting schedule, how service is measured, and what happens to unvested money on termination.
5. Distributions, loans and withdrawals
What events allow a payout, what forms of payment exist, whether loans and in-service withdrawals are permitted, and the process for requesting them.
6. Claims and appeals procedures
How a participant files a claim, how long the plan has to respond, and how to appeal a denial.
7. Statement of ERISA rights
The required statement of participant rights, including the right to receive plan documents on request and the right to bring an action after exhausting the plan’s appeal process.
The SMM: how you keep the SPD current
When you amend the plan in a way that materially changes information in the SPD, you owe participants a summary of material modifications. Practically, the SMM is a short notice describing what changed and when it takes effect. Sponsors have two acceptable paths: issue an SMM, or issue a fully restated SPD that already incorporates the change.
Amendments that usually require an SMM include changing the match formula, adding or removing automatic enrollment, changing eligibility or entry dates, changing the vesting schedule, adding or eliminating loans or hardship withdrawals, changing the plan year, or a merger that moves participants into a different plan. When you are unsure whether a change is “material,” the safer answer is to tell participants.
Timing, without inventing deadlines
The safest way for a sponsor to handle SPD and SMM timing is to work off your own plan’s calendar and your document provider’s written schedule rather than a remembered rule of thumb. Confirm the exact windows with your document provider or ERISA counsel and put them on a written compliance calendar. The framework is consistent: new participants get an SPD reasonably soon after they become covered; a restated SPD is redistributed on the regular cycle ERISA requires; and an SMM follows a material amendment within the period tied to the plan year in which the change was adopted.
Delivery and proof of delivery
Distribution has to be reasonably calculated to ensure actual receipt.
Paper delivery
Hand delivery at work or first-class mail both work.
Electronic delivery
Electronic disclosure is permitted, but only under specific conditions — generally that the recipient has work-related computer access as an integral part of their job, or has affirmatively consented, plus notice that the document is available, how to get a paper copy free of charge, and reasonable measures to confirm delivery.
Who is on the list
Participants includes more people than your active payroll. Terminated employees with an account balance, participants on leave, alternate payees under a qualified domestic relations order, and beneficiaries receiving benefits are all entitled to receive the SPD. Building your distribution list from the recordkeeper’s participant roster rather than the active-employee census is the practical fix.
Evidence to retain
Keep the version of the SPD that was distributed, the date, the method, the population it went to, the electronic-consent records where applicable, and any notice that accompanied it. “We’re sure we sent it” is not evidence. This is the same documentation discipline that carries a plan through plan audit readiness.
An eight-step SPD self-check
- Pull the executed plan document, the adoption agreement, and every amendment signed since the last restatement.
- Pull the SPD version you are currently handing to new hires, and note its date.
- Compare eligibility, entry dates, the compensation definition, the contribution formulas and the vesting schedule line by line.
- List every amendment since the SPD’s date and mark which ones changed something the SPD describes.
- For each of those, confirm an SMM was issued and distributed — or that a restated SPD covered it.
- Rebuild the distribution list from the recordkeeper roster, including terminated participants with balances, beneficiaries and alternate payees.
- Verify your electronic delivery method actually meets the conditions for everyone on that list, and identify who needs paper.
- File the proof: version, date, method, population, consents. If you cannot produce it, redistribute and start the file now.
If steps 3 through 5 turn up a mismatch, stop and get advice before you “fix” the SPD. Sometimes the summary is wrong and the document is right; sometimes the plan has been operating the way the SPD describes, which means the document needs a corrective amendment. Those are very different corrections, and choosing the wrong one makes the record worse. The same logic applies to any document-versus-operations mismatch.
Where sponsors get hurt
- No proof of distribution. An investigator asking for the SPD and its delivery record will not accept a template pulled from a provider portal after the fact.
- Amendment drift. Several years of amendments with no SMMs means participants are operating on a description of a plan that no longer exists.
- Restatement gaps. A plan document restatement generates a new SPD; if it never went out, the restatement created a disclosure failure rather than curing one.
- The unreachable population. Terminated participants with balances are the group most likely to be missed — and the group most likely to have missing participant issues layered on top.
What you can delegate and what stays with the employer
Drafting the SPD, producing SMM language after an amendment, maintaining version control, building the distribution list from the recordkeeper roster, executing delivery and holding the proof file — all of that can be delegated to a professional 3(16) plan administrator.
What cannot be delegated is the settlor side: deciding to amend the plan, choosing the match formula, selecting who is eligible, and signing the document. Employer-only data — hire and termination dates, compensation, employment classifications — also stays with you, because no service provider can generate it. Understanding that split is the core of any honest conversation about transferring fiduciary liability, and it is why the 3(16), 3(21), 3(38) and 402(a) roles are worth understanding before you sign a service agreement.
Why the named fiduciary question matters here
Admin316 accepts the ERISA 402(a) named-fiduciary appointment — the appointment most providers decline — and takes on the 3(16) administrative duties that come with it, including participant disclosure and the documentation trail behind it. You still own the settlor decisions and your own payroll data. Everything else, including the SPD and SMM cycle, becomes someone else’s job to run and to prove.
If you cannot currently produce your SPD, its distribution date, and the SMMs for every amendment since, that is the place to start. Book a plan sponsor review with Admin316 and we will walk your document, your SPD and your disclosure file together.
