Trustees of Iron Wkers' Mid-America Supplemental of Lansing, Illinois sponsors Iron Workers' Mid-America Supplemental Monthly Annuity (Sma) Fund, a defined contribution plan. Its Form 5500 for the plan year ending 31 Dec 2025 shows 7,052 participants (6,729 active) and $892M in net assets. It is a multiemployer plan, maintained under collective bargaining agreements with more than one employer.
Net assets came to $110,977 per participant in plan year 2024, well above the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and well above the $54,962 median for defined contribution plans in construction. 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 $40.8M during the year, or $6,064 per active participant against a same-size median of $2,424; participants contributed — and $35K arrived as rollovers and other contributions. Benefits paid out totalled $41.4M.
Schedule C lists 8 service provider organisations paid $5,000 or more, with reported compensation of $826K: $117 per participant, well above the same-size median of $53.38. Administrative expenses charged to the plan were $1.9M. 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 $348M in 2009 to $892M in 2025 (up 156%), and participants from 7,897 to 7,052 (down 11%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

Questions and answers
How big is Iron Workers' Mid-America Supplemental Monthly Annuity (Sma) Fund?
7,052 participants at the end of the plan year ending 31 Dec 2025, of whom 6,729 were active employees, with net assets of $891,576,552. 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 Trustees of Iron Wkers' Mid-America Supplemental contribute per participant?
The filing reports $40,807,221 in employer contributions for the year, which is $6,064 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 $826,067 in compensation to service provider organisations, $117 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 $1,921,227. 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 Trustees of Iron Wkers' Mid-America Supplemental. Recordkeeping or administration: John Hancock and Legacy Professionals LLP. Investment advisory or management: Fiducient Advisors LLC. 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 Jan 2025 to 31 Dec 2025, received by the Department of Labor on 8 Jun 2026. 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.
