Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. Form 5500 contains no individual account balances. Look up the original filing at EFAST2.
Mdu Resources Group, Inc. Pension Plan for Collective Bargaining Unit Employees is a defined benefit pension plan sponsored by Mdu Resources Group, Inc. of Bismarck, North Dakota. For the plan year ending 31 Dec 2024 it reported 468 participants, 94 of them active, and net assets of $51.9M.
Net assets came to $110,922 per participant, well above the $87,254 median for defined benefit plans with 250 to 499 participants and well below 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 $1.6M for the year ($16,751 per active participant) and benefits paid were $5.1M. 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 3 service provider organisations paid $5,000 or more, with reported compensation of $84K: $179 per participant, well below the same-size median of $413. Administrative expenses charged to the plan were $461K. 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 $61.6M in 2009 to $51.9M in 2024 (down 16%), and participants from 773 to 468 (down 39%).
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

468 participants at the end of the plan year ending 31 Dec 2024, of whom 94 were active employees, with net assets of $51,911,336. Among defined benefit plans that places it in the 250 to 499 participants band, which held 873 plans in plan year 2024.
What does Mdu Resources Group, Inc. contribute per participant?
The filing reports $1,574,562 in employer contributions for the year, which is $16,751 per active participant; the median for plans of the same type and size was $11,032 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 $83,961 in compensation to service provider organisations, $179 per participant or 0.16% of net assets. The same-size median among plans reporting any Schedule C compensation was $413 per participant. Administrative expenses on Schedule H were $460,822. 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 Mdu Resources Group, Inc.. Recordkeeping or administration: Principal Trust Company and Principal Life Insurance Company. Investment advisory or management: Principal Life Insurance Company. Trustee or custodian: Principal Trust Company and Principal Life Insurance Company. The financial statements were audited by Deloitte and Touche 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 15 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.
