Plaintiffs have filed a class-action lawsuit against Chicago-based Aon PLC, alleging the company breached its fiduciary duties by prioritizing its own financial interests over those of employee benefit plan participants. The litigation centers on commissions the firm allegedly collected between 2020 and 2024.
Why it matters
This case highlights the risks of potential conflicts of interest when employers act as both the fiduciary selecting benefit programs and the broker receiving fees from them. It underscores how plan management decisions can impact the costs and quality of benefits for thousands of employees.
Aon allegedly collected $14.83 million in commissions and fees between 2020 and 2024 from its benefit plan. During this period, the plan's enrollment grew from 12,890 participants in 2020 to 13,112 in 2024.
The players
Aon PLC
A global professional services firm that provides retirement, health, and risk benefits to employees.
Dale Daniel
A lead plaintiff named in the class-action lawsuit filed against the Aon PLC benefits program.
The details
The lawsuit alleges that Aon violated the Employee Retirement Income Security Act (ERISA) by using its discretionary authority to select insurance carriers that paid it commissions. By acting as both the decision-maker and the beneficiary of those choices, the plaintiffs argue the company breached its duty of loyalty to plan participants. The suit aims to appoint an independent fiduciary to manage the plan moving forward.
Timeline
The Aon Benefit Plan had 12,890 participants in 2020.
The company allegedly collected commissions between 2020 and 2024.
The proposed class period for the lawsuit begins on October 23, 2020.
The lawsuit was filed in federal court on October 23, 2026.
The Aon Benefit Plan had 13,112 participants in 2024.
Money Landscape
This litigation tests the boundaries of prohibited transactions under ERISA by challenging the alignment of corporate commissions and employee benefits. It follows a broader legal trend where participants increasingly scrutinize the fee structures and administrative arrangements of workplace plans.
Employees enrolled in corporate benefit plans should review their plan documentation to understand how fees are disclosed and how providers are compensated. If you have concerns about the management of your specific workplace plan, consider discussing your options with a qualified benefits attorney.
The takeaway
This lawsuit serves as a reminder to monitor the administrative costs associated with your employer-provided benefits. Keep documentation of your benefit selections and, if you believe a plan is being mismanaged, consult with a financial professional regarding your rights under ERISA.
