How the Plan Works
Enrollment
You can enroll or opt out of the Plan:
  • as soon as you are eligible, or as of the first day of any future pay period, as long as you remain eligible, or
  • after 30 days of employment if you do not opt out of the Plan, you will automatically be enrolled in the Plan.
Your participation is effective the first day of the next available pay period. Contributions will be deducted from your paycheck for that pay period and invested as of the next business day.
Contributions will not be made retroactively.
To meet the transaction submission deadline for enrollment, go online to PeopleLink (www.mmcpeoplelink.com), click MMC 401(k) Plan via the Finances tab and from the right navigation bar, select Enroll, view, change benefits under Take Action or call the Employee Service Center at +1 866 374 2662 by 4 p.m. Eastern time at least 11 business days (if you are on the semi-monthly payroll) or 5 business days (if you are on the weekly payroll) before the next pay date. If you do not give at least 11 or 5 business days' notice respectively, your enrollment will be effective the first day of the second pay period following your notice. Contact the Employee Service Center if a holiday falls within the processing cycle to confirm the transaction submission deadline.
If you enroll for the first time and make no investment direction election (whether through active enrollment or automatic enrollment), your future employee before-tax and after-tax contributions and Company Matching Contributions (if you have completed a year of vesting service) will be invested automatically in one of the LifePath Portfolios (the LifePath Portfolio that most closely matches your retirement year—based on the Plans' normal retirement age of 65).
