 Plan Overview

The RMP Supply Trim 401(k) Plan is designed to help you prepare for your retirement future with
generous employer contributions and flexible savings options.

🎉 Employer Match Contribution 

RMP Supply Trim provides a Safe Harbor non-elective contribution of 3% of your eligible pay to your 401(k) account. You may also receive additional discretionary profit-sharing contributions each year. This is extra money to help you save for retirement.

Plan Highlights

  • Eligibility: Age 21 + 1 year of service (1,000 hours).
  • Entry Date: 1st day of 1st or 7th month of Plan Year after
                     reaching eligibility.
  • Employer Match: Safe Harbor non-elective - 3% of pay.
  • Roth Option: Available
  • Loans: Loans are not permitted.

Vesting Schedule

Your own contributions and Safe Harbor matching contributions are always 100% yours. However, if your employer elects to make a profit-sharing contribution, those amounts are subject to a 6-year graded vesting schedule:

Frequently Asked Questions

Quick answers to common questions about your 401(k) plan.


When can I start participating in the plan? ▼
You’re eligible once you’ve reached age 21 and completed 1 year of service with at least 1,000 hours worked. Your participation begins on the 1st day of the 1st month or 7th month of the Plan Year after you meet both requirements.
How much does RMP Supply Trim, Inc. contribute? ▼
RMP Supply Trim provides a Safe Harbor non-elective contribution of 3% of your eligible pay, regardless of whether you contribute to the plan yourself.
What is vesting, and how does it work?▼
Vesting determines your ownership of employer contributions. Your own contributions are always 100% yours. Employer contributions vest on a 6-year graded schedule: 0% under 2 years, 20% at 2 years, 40% at 3 years, 60% at 4 years, 80% at 5 years, and 100% at 6 or more years.
Can I take a loan from my 401(k)? ▼
No, loans are not permitted.
What's the difference between Traditional and Roth contributions? ▼
Traditional 401(k) contributions are made with pre-tax dollars (reducing your current taxable income), and you pay taxes when you withdraw in retirement. Roth 401(k) contributions are made with after-tax dollars, but qualified withdrawals in retirement are tax-free. Both options are available under your plan.
How do I change my contribution amount or investments? ▼
You can update your contribution rate or investment elections at any time by logging into your account online at myplan.johnhancock.com.
What happens to my account if I leave the company? ▼
You keep your vested balance. You can roll it over to an IRA or a new employer's plan, leave it in the plan if eligible, or take a distribution subject to applicable taxes and penalties. Accounts of $5,000 or less may be automatically distributed.
