Aon Retirement Pension Plan
Sponsored by Aon Corporation, Atlanta, GA
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. Form 5500 contains no individual account balances. Look up the original filing at EFAST2.
Aon Corporation of Atlanta, Georgia sponsors Aon Retirement Pension Plan, a cash balance pension plan. Its Form 5500 for the plan year ending 31 Dec 2024 shows 13,598 participants (1,477 active) and $1.44B in net assets.
Net assets came to $105,696 per participant, above the $87,623 median for defined benefit plans with 5,000 to 24,999 participants and below the $119,983 median for defined benefit plans in finance and insurance. The figure is an average across everyone in the plan, including former employees with small balances; Form 5500 holds no individual account data.
Employer contributions were $18.3M for the year ($12,388 per active participant) and benefits paid were $110M. In a defined benefit plan the employer's contribution follows funding rules rather than a match formula, so it can swing widely from year to year.
Schedule C lists 7 service provider organisations paid $5,000 or more, with reported compensation of $1.8M: $132 per participant, well below the same-size median of $232. Administrative expenses charged to the plan were $12.7M. Schedule C does not capture every cost: fees netted from fund returns and fees the employer pays directly are outside it.
Across the filings on record, net assets went from $2.18B in 2020 to $1.44B in 2024 (down 34%), and participants from 18,622 to 13,598 (down 27%).
The independent accountant's opinion on the financial statements was unmodified (unqualified).

Questions and answers
How big is Aon Retirement Pension Plan?
13,598 participants at the end of the plan year ending 31 Dec 2024, of whom 1,477 were active employees, with net assets of $1,437,247,822. Among defined benefit plans that places it in the 5,000 to 24,999 participants band, which held 651 plans in plan year 2024.
What does Aon Corporation contribute per participant?
The filing reports $18,297,685 in employer contributions for the year, which is $12,388 per active participant; the median for plans of the same type and size was $9,468 in plan year 2024. Form 5500 reports the total only. It does not state the match formula, and the per-participant figure is an average, not any one person's contribution.
What fees does the plan pay and how do they compare?
Schedule C reports $1,792,078 in compensation to service provider organisations, $132 per participant or 0.13% of net assets. The same-size median among plans reporting any Schedule C compensation was $232 per participant. Administrative expenses on Schedule H were $12,698,227. Investment costs deducted inside mutual funds and other pooled vehicles are not itemised on Form 5500, so these figures are a floor rather than a full cost.
Who runs the plan?
The sponsor is Aon Corporation. Investment advisory or management: Legal & General Investment, Dodge & Cox and Pacific Investment MGT Company. Trustee or custodian: Northern Trust Company. The financial statements were audited by Ernst & Young, LLP. Form 5500 also names the plan administrator's signer and other individuals; this site publishes organisations only.
Was the audit opinion unqualified?
The filing reports an unmodified (unqualified) opinion. Unmodified (formerly "unqualified") is the standard clean opinion.
How current is this, and does it show my balance?
This is the Form 5500 for the plan year 1 Jan 2024 to 31 Dec 2024, received by the Department of Labor on 7 Oct 2025. Filings are due seven months after the plan year ends, or nine and a half with an extension, so the public record always runs a year or more behind. It contains plan-level totals only: no individual balances, contributions or names of participants exist in the data.
