AON Corporation 401(k): best low-cost funds
AON Savings Plan · Plan #020 · Atlanta, GA
Suggested simple Boglehead mix
The public data doesn't show enough index funds from this plan to suggest a full mix. A typical Boglehead approach: look in your menu for a US total market or S&P 500 index fund, an international index fund, and a US bond index fund, all with expense ratios under about 0.10%. Or use one low-cost target-date index fund. How the 3-fund portfolio works.

FAQ
What are the best low-cost funds in the AON Corporation 401(k)?
The free public data doesn't list enough of the AON Corporation plan's index funds to say. Look in your plan's fee disclosure (404a-5 notice) for a US stock index fund, an international index fund and a bond index fund with low expense ratios.
Can I build a three-fund portfolio in the AON Corporation 401(k)?
Possibly. Many large plans offer the three building blocks, but the public data for this plan doesn't confirm it. A low-cost target-date index fund is a common one-fund alternative.
How big is the AON Corporation 401(k) plan?
The plan reported about $6.6B in net assets and 24,239 participants with balances for plan year 2024, according to its DOL Form 5500 filing.
Where does this data come from?
From public U.S. Department of Labor Form 5500 filings (EFAST2) and, where noted, the plan's SEC Form 11-K. Data can be outdated or incomplete, and this page is not financial advice.
