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, District No. 9 International Association of Machin Aerospace Workers Pension Plan covered 13,905 participants and held $749M in net assets. The plan is a defined benefit pension plan sponsored by Joint Board of Trustees of District 9 I.A.M & A.W. Pension Trust of Bridgeton, Missouri. It is a multiemployer plan, maintained under collective bargaining agreements with more than one employer.
Net assets came to $53,884 per participant, well below the $87,623 median for defined benefit plans with 5,000 to 24,999 participants and well below the $67,961 median for defined benefit 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.
Employer contributions were $19.9M for the year ($10,363 per active participant) and benefits paid were $69.4M. In a defined benefit plan the employer's contribution follows funding rules rather than a match formula, so it can swing widely from year to year.
Schedule C lists 9 service provider organisations paid $5,000 or more, with reported compensation of $998K: $71.76 per participant, well below the same-size median of $232. Administrative expenses charged to the plan were $2.2M. 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 $549M in 2009 to $749M in 2024 (up 37%), and participants from 16,818 to 13,905 (down 17%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

Questions and answers
How big is District No. 9 International Association of Machin Aerospace Workers Pension Plan?
13,905 participants at the end of the plan year ending 31 Dec 2024, of whom 1,925 were active employees, with net assets of $749,261,127. Among defined benefit plans that places it in the 5,000 to 24,999 participants band, which held 651 plans in plan year 2024.
What does Joint Board of Trustees of District 9 I.A.M & A.W. Pension Trust contribute per participant?
The filing reports $19,949,163 in employer contributions for the year, which is $10,363 per active participant; the median for plans of the same type and size was $9,468 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 $997,801 in compensation to service provider organisations, $71.76 per participant or 0.13% of net assets. The same-size median among plans reporting any Schedule C compensation was $232 per participant. Administrative expenses on Schedule H were $2,231,984. 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 Joint Board of Trustees of District 9 I.A.M & A.W. Pension Trust. Investment advisory or management: Boston Trust Walden. Trustee or custodian: Boston Trust Walden and Enterprise Bank. 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 2024 to 31 Dec 2024, received by the Department of Labor on 15 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.
