Key Differences in Fiduciary Liability Insurance

Standalone Options and Package Form

AIG describes Fiduciary Edge and related plan-fiduciary options, including IRS Audit Protector, settlor coverage and an ACA extension, subject to the offered form. Liberty Mutual includes fiduciary liability in ProShield, a package policy combining multiple management-liability coverages. A buyer should compare the package's included protections with AIG's selected extensions and determine whether the broader structure fits its other management-liability needs. 3 6

Organization Eligibility and Terms

Liberty Mutual scopes ProShield to private and not-for-profit organizations, but does not establish eligibility for a particular plan or sponsor. AIG identifies benefit-plan overseers, including those responsible for 401(k), pension and welfare plans, without a universal eligibility schedule. The quote should identify covered plans and insured people; the public audience descriptions alone cannot confirm a sponsor qualifies. 3 6
