What Is Umbrella and Excess Liability Insurance?
Umbrella or excess insurance adds liability limits above the policies named in the quote after a covered claim exhausts their limits. It may fit if a contract sets higher limits; check which primary policies are listed and any gaps between them. 11,12,13,14,15
Key Differences in Umbrella and Excess Liability Insurance
Form and underlying coverage
Founder Shield describes umbrella as additional liability above underlying policies, including bodily injury, property damage, and personal-liability claims such as libel or slander. AIG describes excess casualty protection for severe liabilities and lead umbrella that may integrate with other casualty lines. The records frame the coverage differently, so a business should confirm whether the quote is commercial-only and which underlying policies it follows. 3 6
Capacity and buyer support
Founder Shield says it places the policy with carriers rated A- or better by AM Best but does not identify the specific insurer. AIG also says the legal insurer and tower structure are account-specific. Ask both for the carrier name, admitted status, and declarations before binding. 3 6
