An umbrella policy may build on the protections of underlying, primary policies in two distinct ways. First, a policy might offer limits beyond what primary policies are able to provide. For example, a general liability insurance policy may have a maximum limit of $3 million. A commercial umbrella policy might build on this coverage and add another $5 million worth of protection, effectively giving a business $8 million worth of coverage. Second, an umbrella policy may fill in one or more coverage gaps that primary policies have. A business’ general liability policy, for instance, might have an exclusion that leaves the business exposed to possible lawsuits. An umbrella policy’s terms and conditions may cover this exclusion, offering the business protection where it previously had none.
