Iso New England Inc. Supplemental Retirement and Savings Plan is a 401(k) plan sponsored by Iso New England Inc. of Holyoke, Massachusetts. For the plan year ending 31 Dec 2024 it reported 845 participants, 678 of them active, and net assets of $321M.
Net assets came to $380,225 per participant, well above the $46,267 median for defined contribution plans with 500 to 999 participants and well above the $137,166 median for defined contribution 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.
The employer contributed $6.8M during the year, or $9,995 per active participant against a same-size median of $1,934; participants contributed $10.6M and $726K arrived as rollovers and other contributions. Benefits paid out totalled $20.3M.
Schedule C lists 2 service provider organisations paid $5,000 or more, with reported compensation of $169K: $200 per participant, well above the same-size median of $113. Administrative expenses charged to the plan were $169K. 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 $51.1M in 2009 to $321M in 2024 (up 529%), and participants from 520 to 845 (up 63%).
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 Iso New England Inc. Supplemental Retirement and Savings Plan?
845 participants at the end of the plan year ending 31 Dec 2024, of whom 678 were active employees, with net assets of $321,290,141. 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 Iso New England Inc. contribute per participant?
The filing reports $6,776,546 in employer contributions for the year, which is $9,995 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 $169,380 in compensation to service provider organisations, $200 per participant or 0.05% of net assets. The same-size median among plans reporting any Schedule C compensation was $113 per participant. Administrative expenses on Schedule H were $169,380. 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 Iso New England Inc.. Recordkeeping or administration: Fidelity Investments Institutional. The financial statements were audited by Meyers Brothers Kalicka, PC. 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 8 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.
