You can enroll or opt out of 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 ibenefitcenter via MMC PeopleLink (www.mmcpeoplelink.com) or call the MMC 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 MMC 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 service) will be invested automatically in the Vanguard Wellington Fund.
