Aon Hewitt
Most often reported for recordkeeping and administration
Form 5500 information is as filed by the plan administrator with the Department of Labor and may be amended. Figures reflect the plan year shown, not current balances. Schedule C lists only providers a plan paid $5,000 or more, and is filed only by plans with 100 or more participants.
For plan year 2024, 78 retirement plans with 100 or more participants reported paying Aon Hewitt $5,000 or more. Those plans cover 737,025 participant records, and the service most often reported is recordkeeping and administration.
Reported compensation from those plans, direct and indirect, totalled $29.6M. Per plan, the median was $46.62 per participant, with the middle half of plans between $15.43 and $149. These are amounts plans reported paying this organisation, not a price list: they depend on which services each plan buys and on how much is paid through fund expenses instead.
Its client plans are most numerous in Illinois (14), New Jersey (9) and Texas (8).
In 2009 it appeared on 636 such filings; in 2024, 79 (down 88%). Yearly counts include every filing that names it, so they can run slightly above the number of plans with pages here, and name or EIN changes after mergers can break the series.

Plans served by year
Matched by employer identification number. A merger or a change of filing entity starts a new series, so a drop to zero is not a loss of clients by itself.
