Center For Social Dynamics 401(k) Plan
Center For Social Dynamics Inc. · Concord, CA · EIN 371749452 · Plan 001 · Form 5500 for plan year 2024
What Center For Social Dynamics put into the plan, per active participant
Not on this filing
Schedule H leaves the employer contribution line blank on this filing. A blank line is an unfilled line, not a zero, and one sponsor often files several plans, so the employer money can sit in another plan of the same sponsor.
Nothing is filled in from an average, from another year or from another plan.

What the plan cost, per participant
$6.52
The plan paid $6.52 per participant in plan-paid administrative expenses in plan year 2024, cheaper than 97% of plans with 1,000–4,999 participants. The middle plan of that size paid $84.96.
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
Not scored
This filing reports one of the two amounts the score is built from, so it takes none. Schedule H leaves the employer contribution line blank on this filing. A blank line is an unfilled line, not a zero, and one sponsor often files several plans, so the employer money can sit in another plan of the same sponsor.
It keeps whichever of the two it does report, above. Nothing is filled in from an average, from another year or from another plan, because a two-part score computed on one part is a different measure wearing the same name.
What the score would read, on a filing that carries both: 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.

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 Center For Social Dynamics 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 Vanguard ↗.
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
3rd percentile
$6.52 per participant in plan-paid administrative cost, cheaper than 97% of plans with 1,000–4,999 participants.
What to check next
A blank line is not a zero
Schedule H leaves the employer contribution line unfilled on this filing, which is not the same as reporting nothing was paid in. Your own statement, on Vanguard ↗, shows what reached your account.
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 Vanguard ↗. What you may put in during a year is set by the IRS and not by the plan: this year’s limits ↗.

A blank employee line against a filled employer line would read as every dollar coming from the employer, which is a gap in the filing rather than a fact about the plan, so no share is shown. | not stated on this filing |

Filings lag by design: a plan can file up to 9½ months after its year ends, so this is the newest data on file. Why filings lag
