Dudek & Bock 401(k) Tax Deferred Savings Plan is a 401(k) plan sponsored by Dudek & Bock Spring MFG of Chicago, Illinois. For the plan year ending 31 Dec 2024 it reported 198 participants, 157 of them active, and net assets of $17.1M.
Net assets came to $86,154 per participant, well above the $60,185 median for defined contribution plans with 100 to 249 participants and well 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 $83K during the year, or $530 per active participant against a same-size median of $2,447; participants contributed $602K and $10K arrived as rollovers and other contributions. Benefits paid out totalled $2.4M.
Schedule C lists 2 service provider organisations paid $5,000 or more, with reported compensation of $17K: $83.35 per participant, well below the same-size median of $194. Administrative expenses charged to the plan were $17K. 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 $8.2M in 2009 to $17.1M in 2024 (up 109%), and participants from 211 to 198 (down 6%).
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 Dudek & Bock 401(k) Tax Deferred Savings Plan?
198 participants at the end of the plan year ending 31 Dec 2024, of whom 157 were active employees, with net assets of $17,058,414. Among defined contribution plans that places it in the 100 to 249 participants band, which held 21,996 plans in plan year 2024.
What does Dudek & Bock Spring MFG contribute per participant?
The filing reports $83,172 in employer contributions for the year, which is $530 per active participant; the median for plans of the same type and size was $2,447 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 $16,503 in compensation to service provider organisations, $83.35 per participant or 0.10% of net assets. The same-size median among plans reporting any Schedule C compensation was $194 per participant. Administrative expenses on Schedule H were $16,503. 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 Dudek & Bock Spring MFG. Recordkeeping or administration: ADP, Inc.. The financial statements were audited by Miller Cooper & Co. Ltd.. 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 3 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.
