MMC Benefits Handbook
What Pay Counts
BEP benefits are calculated using the same pay used in the Retirement Plan. However, the pay used to calculate the BEP benefit is not subject to IRC limits that can potentially cap the amount of benefits that can be paid by the Retirement Plan. For example, the IRC limit on the amount of annual compensation that can be taken into account in calculating benefits payable from a Tax-Qualified Plan is $265,000 for 2016. The BEP, a non-qualified plan, pays benefits in excess of these limits. See "What Pay Counts" in the Marsh & McLennan Companies Retirement Plan for additional details.
Any pay attributable to your employment with Marsh McLennan after December 31, 2016 is not included in determining your BEP benefit.
