MassMutual Pension Plan is a cash balance pension plan sponsored by Massachusetts Mutual Life Insurance Company of Springfield, Massachusetts. For the plan year ending 31 Dec 2024 it reported 22,293 participants, 10,957 of them active, and net assets of $2.40B.
Net assets came to $107,630 per participant, above the $87,623 median for defined benefit plans with 5,000 to 24,999 participants and below the $119,983 median for defined benefit plans in finance and insurance. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Schedule C lists 4 service provider organisations paid $5,000 or more, with reported compensation of $2.8M: $127 per participant, well below the same-size median of $232. Administrative expenses charged to the plan were $8.9M. 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 $1.32B in 2009 to $2.40B in 2024 (up 82%), and participants from 19,498 to 22,293 (up 14%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

What does Massachusetts Mutual Life Insurance Company contribute per participant?

What fees does the plan pay and how do they compare?
Schedule C reports $2,829,923 in compensation to service provider organisations, $127 per participant or 0.12% of net assets. The same-size median among plans reporting any Schedule C compensation was $232 per participant. Administrative expenses on Schedule H were $8,897,748. 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.

Trustee or custodian: State Street Bank and Trust Company. The financial statements were audited by KPMG. 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. 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.
