Acorn Engineering Company, Inc. of City of Industry, California sponsors Acorn Engineering Company, Inc. 401(k) Plan, a 401(k) plan. Its Form 5500 for the plan year ending 31 Dec 2024 shows 877 participants (669 active) and $34.3M in net assets.
Net assets came to $39,090 per participant, below the $46,267 median for defined contribution plans with 500 to 999 participants and well below 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 $122K during the year, or $183 per active participant against a same-size median of $1,934; participants contributed $1.7M and $173K arrived as rollovers and other contributions. Benefits paid out totalled $2.5M.
Schedule C lists 3 service provider organisations paid $5,000 or more, with reported compensation of $102K: $116 per participant, close to the same-size median of $113. Administrative expenses charged to the plan were $102K. 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 $14.9M in 2009 to $34.3M in 2024 (up 131%), and participants from 685 to 877 (up 28%).
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 Acorn Engineering Company, Inc. 401(k) Plan?
877 participants at the end of the plan year ending 31 Dec 2024, of whom 669 were active employees, with net assets of $34,281,502. Among defined contribution plans that places it in the 500 to 999 participants band, which held 10,588 plans in plan year 2024.
What does Acorn Engineering Company, Inc. contribute per participant?
The filing reports $122,328 in employer contributions for the year, which is $183 per active participant; the median for plans of the same type and size was $1,934 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 $101,515 in compensation to service provider organisations, $116 per participant or 0.30% of net assets. The same-size median among plans reporting any Schedule C compensation was $113 per participant. Administrative expenses on Schedule H were $101,514. 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 Acorn Engineering Company, Inc.. Recordkeeping or administration: Empower Annuity Insurance Company O. Investment advisory or management: LPL Financial and Empower Advisory Group, LLC. The financial statements were audited by Beach Freeman Lim & Cleland, 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 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 29 Jul 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.
