MMC Benefits Handbook
When Contributions Start
Your contributions will start on:
  • The first of the month coincident with or following your effective date of enrollment as long as you are actively employed. Your contributions will be prorated based on the number of full months remaining in the calendar year and your level of coverage under the Marsh & McLennan Companies $1,600 Deductible Plan or $3,200 Deductible Plan.
  • January 1 if you enroll during Annual Enrollment.
Participation does not continue automatically from plan year to plan year; you have to enroll during the Annual Enrollment period.
Expenses incurred before your participation begins cannot be reimbursed.
