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 Engineering Consulting Services, Ltd. 401(k) Retirement Plan?
3,098 participants at the end of the plan year ending 31 Dec 2025, of whom 2,560 were active employees, with net assets of $220,225,586. Among defined contribution plans that places it in the 1,000 to 4,999 participants band, which held 10,207 plans in plan year 2024.
What does Engineering Consulting Services, Ltd. contribute per participant?
The filing reports $5,949,457 in employer contributions for the year, which is $2,324 per active participant; the median for plans of the same type and size was $2,045 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 $333,009 in compensation to service provider organisations, $107 per participant or 0.15% of net assets. The same-size median among plans reporting any Schedule C compensation was $82.08 per participant. Administrative expenses on Schedule H were $333,009. 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 Engineering Consulting Services, Ltd.. Recordkeeping or administration: Capital Group Retirement Plan Svcs.. Investment advisory or management: Morgan Stanley. Trustee or custodian: Capital Group Retirement Plan Svcs.. The financial statements were audited by Baker Tilly US, 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 2025 to 31 Dec 2025, received by the Department of Labor on 29 Jul 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.
