We can provide you with protection against catastrophic liability claims. An umbrella policy acts as an excess coverage over your primary liability policies. Its limits apply in addition to the provided by underlying coverage. This form provides a higher limit of coverage that is excess over scheduled underlying policies. It is used in one of three ways, (1) to provide additional limits of protection over the coverage listed in your underlying schedule, (2) to act as primary coverage if your underlying limits are exhausted, and (3) to provide coverage for some risks, subject to retention, when your primary coverage does not.
