Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. Form 5500 contains no individual account balances. Look up the original filing at EFAST2.
In the plan year ending 31 Dec 2024, Marmon Employees' Retirement Plan covered 22,250 participants and held $1.69B in net assets. The plan is a 401(k) plan sponsored by Marmon Holdings, Inc. of Chicago, Illinois.
Net assets came to $76,159 per participant, above the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and above the $62,303 median for defined contribution plans in manufacturing. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
The employer contributed $70.0M during the year, or $4,939 per active participant against a same-size median of $2,424; participants contributed $59.1M and $14.5M arrived as rollovers and other contributions. Benefits paid out totalled $181M.
Schedule C lists 6 service provider organisations paid $5,000 or more, with reported compensation of $1.5M: $66.50 per participant, above the same-size median of $53.38. Administrative expenses charged to the plan were $1.5M. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $872M in 2014 to $1.69B in 2024 (up 94%), and participants from 11,387 to 22,250 (up 95%).
The independent accountant's opinion on the financial statements was unmodified (unqualified), from an audit whose scope was limited under ERISA section 103(a)(3)(C) to exclude investment information certified by a bank or insurer.

Questions and answers
How big is Marmon Employees' Retirement Plan?
22,250 participants at the end of the plan year ending 31 Dec 2024, of whom 14,175 were active employees, with net assets of $1,694,547,897. Among defined contribution plans that places it in the 5,000 to 24,999 participants band, which held 2,605 plans in plan year 2024.
What does Marmon Holdings, Inc. contribute per participant?
The filing reports $70,011,619 in employer contributions for the year, which is $4,939 per active participant; the median for plans of the same type and size was $2,424 in plan year 2024. Form 5500 reports the total only. It does not state the match formula, and the per-participant figure is an average, not any one person's contribution.
What fees does the plan pay and how do they compare?
Schedule C reports $1,479,655 in compensation to service provider organisations, $66.50 per participant or 0.09% of net assets. The same-size median among plans reporting any Schedule C compensation was $53.38 per participant. Administrative expenses on Schedule H were $1,479,655. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is Marmon Holdings, Inc.. Recordkeeping or administration: Empower Annuity Insurance Company and Willis Towers Watson Midwest Inc.. The financial statements were audited by Plante & Moran, PLLC. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an unmodified (unqualified) opinion from a limited-scope audit, in which the accountant did not audit investment information certified by a bank or insurance company. Unmodified (formerly "unqualified") is the standard clean opinion.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Jan 2024 to 31 Dec 2024, received by the Department of Labor on 14 Oct 2025. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
