BHSI publishes portfolio eligibility and fiduciary features; Aon’s practice page does not give policy-level terms. ## Research Scope and Use Use this comparison to evaluate Aon and Berkshire Hathaway Specialty Insurance for Fiduciary Liability Insurance against the same documented criteria. It identifies differences and questions to confirm; it does not select a winner for a particular business. Offering claims are what each provider publishes about this line unless marked otherwise. “Not found” describes the evidence reviewed, not proof that a feature is unavailable. Confirm the insurer, policy wording, limits, retentions, exclusions and cost in an actual quote. ## Summary BHSI publishes portfolio eligibility and fiduciary features; Aon’s practice page does not give policy-level terms.

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.

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.

Aon lists fiduciary coverage in its professional-services practice but does not state a package structure. BHSI targets private companies with at least $10 million in revenue across named sectors, giving buyers concrete screening criteria before comparing its portfolio with an Aon placement. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/public-company/private-company-portfolio/ "Executive First Private Company Portfolio") ### Coverage Terms and Service Berkshire Hathaway Specialty Insurance advertises shared or separate portfolio limits up to $50 million and describes fiduciary features such as full settlor coverage, ACA gap coverage, and fines and penalties. Aon’s overview does not state fiduciary grants or limits. A BHSI buyer should determine whether limits are shared and whether those features are in the quoted form; Aon buyers need comparable wording from the proposed carrier. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/public-company/private-company-portfolio/ "Executive First Private Company Portfolio") ## What to Confirm in Fiduciary Liability Insurance Quotes - Ask BHSI whether the quote uses shared or separate limits and which fiduciary features are included. Ask Aon for carrier, limit structure, and policy wording. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") [8](https://www.bhspecialty.com/us-products/us-executive-and-professional-lines/public-company/private-company-portfolio/ "Executive First Private Company Portfolio") ## Offering Details | Criteria | Aon Fiduciary Liability brokerage and risk-advisory offering | Fiduciary Liability in Executive First Private Company Portfolio | | --- | --- | --- | | Role in This Line | Aon presents Fiduciary Liability as a line its Professional Services Practice helps arrange or advise on for professional-service firms. Aon is describing a global brokerage and advisory service, not issuing the underlying policy. The producing legal entity and carrier for any particular placement are not named on this page. [3](https://www.aon.com/en/capabilities/risk-transfer/professional-services-practice "Professional Services Practice") (Evidence: Company-reported; scope: Aon’s global professional-services practice page.

BHSI identifies large commercial and financial firms with complex risk-transfer needs as targets for this fiduciary policy.

BHSI’s Executive First Fiduciary Liability Policy page lists full settlor coverage, Affordable Care Act gap coverage, and coverage for fines and penalties; it says specialized defense counsel is recommended but not required.

This is a company-described advisory service, not a claim outcome or policy benefit.
