Board of Trustees IUOE Local 399 Deferred Compensation Savings Plan of Chicago, Illinois sponsors IUOE Local 399 Participating Employers Deferred Compensation Employee Savings Plan, a 401(k) plan. Its Form 5500 for the plan year ending 31 Dec 2024 shows 7,098 participants (7,078 active) and $346M in net assets. It is a multiemployer plan, maintained under collective bargaining agreements with more than one employer.
Net assets came to $48,696 per participant, well below the $64,499 median for defined contribution plans with 5,000 to 24,999 participants and below 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 $179K during the year, or $25 per active participant against a same-size median of $2,424; participants contributed $17.7M and $582K arrived as rollovers and other contributions. Benefits paid out totalled $21.9M.
Schedule C lists 7 service provider organisations paid $5,000 or more, with reported compensation of $586K: $82.53 per participant, well above the same-size median of $53.38. Administrative expenses charged to the plan were $591K. 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 $69.8M in 2009 to $346M in 2024 (up 395%), and participants from 3,665 to 7,098 (up 94%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

What does Board of Trustees IUOE Local 399 Deferred Compensation Savings Plan contribute per participant?
The filing reports $178,944 in employer contributions for the year, which is $25 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 $585,782 in compensation to service provider organisations, $82.53 per participant or 0.17% 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 $591,056. 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 IUOE Local 399 Deferred Compensation Savings Plan. Recordkeeping or administration: Benesys, Inc. and John Hancock Retirement Plan Servic. Investment advisory or management: John Hancock Retirement Plan Servic and Strategic Capital Investment Adv. 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 2024 to 31 Dec 2024, received by the Department of Labor on 8 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.
