Oostburg Concrete Products, Inc. · Oostburg, WI · EIN 390789082 · Plan 001 · Form 5500 for plan year 2024
What Oostburg Concrete Products put into the plan, per active participant
$1,992
Oostburg Concrete Products, Inc. put $1,992 into this plan for each of its 123 active participants in plan year 2024. That is the whole employer side, matching money, profit sharing, non-elective and safe-harbor contributions and reallocated forfeitures together, because the Form 5500 reports them on one line, so it is not the match rate.
Oostburg Concrete Products put in less per active participant than 60% of plans with 100–499 participants in construction. The middle plan in that group of 2,201 reported $2,441. Construction comes from business code 238100, which Oostburg Concrete Products, Inc. entered on its own Form 5500. Sponsors pick that code themselves, so a code that does not describe what the employer does ranks the plan against the wrong companies.
What this figure cannot separate: how much Oostburg Concrete Products pays, and how much it puts in
This is dollars, not a rate. A Form 5500 carries no payroll, so the figure reflects both how much the employer puts in and how much the employer pays: two plans running the same formula report different amounts when one pays better. Crossing the peer group with industry holds most of that difference still, and none of it disappears.
This is one plan year, not an average. A true-up, a plan merger or a one-off contribution moves a single year on its own.

What the plan cost, per participant
$354.53
The plan paid $354.53 per participant in plan-paid administrative expenses in plan year 2024, more expensive than 87% of plans with 100–499 participants. The middle plan of that size paid $156.87.
Why a plan this big pays less per person before anything else
Bigger plans pay less per head by construction, because the same negotiated bill divides across more people. That is why this ranking sits inside the plan's own size cohort and is never taken across all plans.
Schedule H reports only what came out of plan assets. Fees the sponsor pays directly, and fees taken inside fund expense ratios, never appear here, so this is a floor and not the all-in cost.
401(k) Monitor Score
32 out of 100
Where this plan stands against plans of its size and industry on two amounts its Form 5500 reports: employer money in per active person, and plan-paid cost per person. It reads no match formula, no vesting schedule and no fund lineup, because a Form 5500 states none of them.
- What the employer put in, per active participant: $1,992. Lower than 60% of plans with 100–499 participants in construction.
- What the plan cost, per participant: $355. Cheaper than 14% of plans with 100–499 participants.

The match and vesting terms, from a Form 11-K
The match formula and the vesting schedule are stated in a Form 11-K, which is filed only by employers whose plan holds company stock. A Form 5500 reports neither.
What Oostburg Concrete Products puts in
Not in public filings for this employer
We have no SEC Form 11-K for this employer, and the Form 5500 this page is built from does not report match terms.
Two places state the terms in full: your plan’s Summary Plan Description, which your employer must provide on request, and your recordkeeper’s site, which for this plan is Empower ↗.
What you contribute to collect all of it
Not in public filings for this employer
The rate that collects the full match is part of the match formula, which a Form 5500 does not report.
Vesting score
Not scored
The vesting schedule is stated in a Form 11-K, and we have none for this employer.
A schedule this cannot read at whole-year anniversaries is left without a number rather than given a middle one.
What the plan costs, against plans of its size
87th percentile
$354.53 per participant in plan-paid administrative cost, more expensive than 87% of plans with 100–499 participants.
What to check next
What to ask about the fees
This plan paid $354.53 per participant out of plan assets, more than 87% of plans with 100–499 participants, where the middle plan paid $156.87. The filing does not say what the difference buys. Two questions put that to a benefits or HR team: what the recordkeeping and administration contract costs, and how much of it comes out of participant accounts rather than being paid by Oostburg Concrete Products. The lines this total is made of are further down.
Your own numbers are not on this page
Every figure here is the whole plan for plan year 2024, taken from one filing and divided by headcounts. Your own contribution rate, your balance and the fees taken from your account are on your recordkeeper’s site, which this filing names as Empower ↗. What you may put in during a year is set by the IRS and not by the plan: this year’s limits ↗.
