| Employer match | Quoted from the filing above | Audit report, p. 50 ↗ |
| Automatic enrollment | Unless they elect otherwise, newly eligible employees and statutory employees are automatically enrolled in the Plan 30 days following date of hire or date of contract endorsement with a 5% before-tax contribution. Investment allocations for participants who do not make an election, including those who participate through automatic enrollment, will be made to the qualified default investment fund designated by the MassMutual Investment Fiduciary Committee. | Audit report, p. 49 ↗ |
| Roth contributions | Before tax and Roth contributions are generally limited by IRC regulations to $23,000 for 2024. Combined employee and employer contributions are limited by IRC regulations to $69,000. Participants who are age 50 or older by year end are eligible to contribute an additional $7,500 for 2024 to the Plan as before tax and/or Roth catch-up contributions. | Audit report, p. 50 ↗ |
| Loans | Participant loans are available under the terms of the Plan document. Participants may borrow a minimum of $1,000, and a maximum equal to the lesser of $50,000 or 50% of their vested account balance, reduced by the highest outstanding loan balance in the last 12 months, from their accounts. The loan is deducted proportionally from the investment funds in which the participant’s account is invested. The rate of interest charged on these loans is the prime rate (at the time of loan application), plus 2%. The interest rates on loans outstanding were 5.25% to 12.00% on December 31, 2024 and 5.25% to 12.00% on December 31, 2023. | Audit report, p. 51 ↗ |
