Key Differences in Umbrella and Excess Liability Insurance
Broker Placement and Program Review
Gallagher places umbrella and excess through outside carriers within a broader casualty program, and its team reviews contracts, forms and coverage gaps before renewal. Liberty Mutual lists umbrella/excess in its commercial catalogue and wholesale coverage list, with commercial products distributed through brokers and agents. For a buyer, Gallagher describes a hands-on program review, while Liberty Mutual’s reviewed record establishes a broker/agent route and a listed coverage option. 6 8
What the Published Coverage Establishes
Gallagher describes customized excess-casualty program design but publishes no attachment points or triggers in the reviewed page. Liberty Mutual names umbrella/excess as an option for wholesale industries, but its cited record likewise does not establish limits or attachment terms. Ask both sides to map the proposed excess layer to your underlying policies. 6 9
