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 Mar 2025, Local No. 1 Suburban 401(k) Savings Plan covered 6,511 participants and held $10.9M in net assets. The plan is a profit-sharing plan sponsored by Board of Trustees Local No. 1 Suburban 401(k) Savings Plan of Downers Grove, Illinois. It is a multiemployer plan, maintained under collective bargaining agreements with more than one employer.
Net assets came to $1,673 per participant, well below the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and well below the $24,581 median for defined contribution plans in administrative and support and waste management services. 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 $2.6M during the year, or $409 per active participant against a same-size median of $2,424; participants contributed $358K and $4,816 arrived as rollovers and other contributions. Benefits paid out totalled $154K.
Schedule C lists 6 service provider organisations paid $5,000 or more, with reported compensation of $353K: $54.27 per participant, close to the same-size median of $53.38. Administrative expenses charged to the plan were $379K. 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 $1.0M in 2020 to $10.9M in 2024 (up 953%), and participants from 2,543 to 6,511 (up 156%).

What does Board of Trustees Local No. 1 Suburban 401(k) Savings Plan contribute per participant?
The filing reports $2,645,481 in employer contributions for the year, which is $409 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 $353,334 in compensation to service provider organisations, $54.27 per participant or 3.2% 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 $378,673. 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 Board of Trustees Local No. 1 Suburban 401(k) Savings Plan. Recordkeeping or administration: Wilson-McShane Corporation and Legacy Professionals LLP. Trustee or custodian: Bank of America. The financial statements were audited by Legacy Professionals LLP. 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. 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 Apr 2024 to 31 Mar 2025, received by the Department of Labor on 30 Dec 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.
