## What Is Aon?

Aon’s U.S. Commercial Risk terms describe brokerage for certain insurance programs, while its Middle Market page describes a dedicated practice for mid-sized organizations across North America. The public materials reviewed do not identify the licensed producer or insurer for a particular placement. Ask which entity will produce each line and which insurer will issue the policy; request jurisdiction details for the proposed placement and ask how compensation and claim notice work for your account.

## What Is Relm Insurance?

Relm suits AI developers distinguishing liability and cyber/Tech E&O through Nova AI from first-party losses caused by third-party AI failures through Resca AI; businesses seeking standard small-business coverage should compare generalist providers.

## What Is Fiduciary Liability Insurance?

Fiduciary liability can protect your company and plan fiduciaries when participants claim mishandling of an employee benefit plan. If you sponsor a retirement or health plan, check who is insured and whether both administration errors and fiduciary-breach claims are addressed. [7](https://www.dol.gov/sites/dolgov/files/ebsa/employers-and-advisers/guidance/field-assistance-bulletins/erisa-fidelity-bonding-requirements.pdf "Field Assistance Bulletin No. 2008-04: Guidance Regarding ERISA Fidelity Bonding Requirements") [8](https://asset.trvstatic.com/download/assets/fri-3001.pdf/c75b6c8e63ca11ee93454641efede6a9 "Fiduciary Liability") [9](https://www.travelers.com/business-insurance/professional-liability-insurance/fiduciary-liability "Fiduciary Liability Insurance")

## Key Differences in Fiduciary Liability Insurance

### Placement and Plan Fit

Relm markets fiduciary liability through brokers to organizations managing benefit plans, specifically mentioning startups and growth-stage companies introducing benefits. Aon lists fiduciary as a line in its Professional Services Practice, whose stated audience is law, accounting, and consulting firms. A startup sponsor can compare those stated client contexts, then confirm underwriting and whether the placement includes its particular pension or health plan. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://relminsurance.com/lines-of-business/financial-lines-insurance/ "Financial Lines Insurance")

### Published Coverage and Services

Relm describes protection for plan sponsors, trustees, administrators, investment committees, and directors or officers with discretionary authority, including legal fees, settlements, and judgments tied to benefit plans. Aon’s reviewed page lists fiduciary but does not name insured roles or covered plan claims. For a committee or trustee, these definitions directly affect who may seek protection; request the policy wording from both brokers. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [6](https://relminsurance.com/lines-of-business/financial-lines-insurance/ "Financial Lines Insurance")

## What to Confirm in Fiduciary Liability Insurance Quotes

- Ask Relm how the form defines discretionary authority and which plan types qualify. Ask Aon for its insured-person definition, carrier, and claims terms.
