Key Differences in Umbrella and Excess Liability Insurance

Structure and attachment

AIG markets admitted and non-admitted excess casualty in lead umbrella, mid-excess, and high-excess positions and advertises up to $75 million per account subject to underwriting. Alliance Risk describes typical limits starting at $1 million and reaching $25 million or more, while distinguishing umbrella’s potential to broaden some terms from excess coverage that follows underlying wording. Buyers should compare attachment points and follow-form language, not just top-line capacity. 3 7

Capacity and account support

Alliance Risk recommends reviewing limits as the business grows and modeling catastrophic loss, alongside vendor and subcontractor risk transfer. AIG describes in-house risk experts, claims specialists, and integration with domestic and foreign casualty platforms. Ask how either placement fits existing underlying policies and which team will model a multi-layer tower. 3 7

What to Confirm in Umbrella and Excess Liability Insurance Quotes

  • Ask AIG which position, attachment point, and legal insurer apply to the proposed tower. 3
  • Ask Alliance Risk to identify underlying policies, limits, and follow-form terms. 7
