Semco Energy, Inc. Union Employees' Retirement Plan is a defined benefit pension plan sponsored by Semco Energy, Inc. of Port Huron, Michigan. For the plan year ending 31 Dec 2024 it reported 240 participants, 62 of them active, and net assets of $81.7M.
Net assets came to $340,467 per participant, well above the $80,635 median for defined benefit plans with 100 to 249 participants and well above the $187,668 median for defined benefit plans in utilities. 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 $91K for the year ($1,461 per active participant) and benefits paid were $3.2M. 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 7 service provider organisations paid $5,000 or more, with reported compensation of $249K: $1,037 per participant, well above the same-size median of $451. Administrative expenses charged to the plan were $273K. 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 $28.7M in 2009 to $81.7M in 2024 (up 184%), and participants from 270 to 240 (down 11%).
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 Semco Energy, Inc. Union Employees' Retirement Plan?
240 participants at the end of the plan year ending 31 Dec 2024, of whom 62 were active employees, with net assets of $81,712,162. Among defined benefit plans that places it in the 100 to 249 participants band, which held 1,156 plans in plan year 2024.
What does Semco Energy, Inc. contribute per participant?
The filing reports $90,557 in employer contributions for the year, which is $1,461 per active participant; the median for plans of the same type and size was $9,975 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 $248,814 in compensation to service provider organisations, $1,037 per participant or 0.30% of net assets. The same-size median among plans reporting any Schedule C compensation was $451 per participant. Administrative expenses on Schedule H were $273,357. 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 Semco Energy, Inc.. Recordkeeping or administration: Aon Consulting, Inc.. Investment advisory or management: Schwartz & Co. and Comerica Bank. Trustee or custodian: Comerica Bank. The financial statements were audited by Grant Thornton 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 13 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.
