MMC Benefits Handbook
Transfers from Non-Participating Marsh & McLennan Companies
If you transfer from a Company that does not participate in the Plan (for example, a company based in another country) to one that does, you are eligible to join the Plan as of the first available pay period after you enroll, provided you otherwise meet the Plan's eligibility requirements. If you have at least one year of service with an affiliated employer at the time of the transfer, you will be eligible to receive Company matching contributions as soon as you start making contributions to the Plan.
