Provides high limits of liability to protect an insured against a catastrophic liability loss. This policy grants liability coverage that stacks on top of the primary liability coverage provided by the insured’s homeowners, personal auto, watercraft, and any other scheduled underlying liability policies. It covers bodily injury (BI), property damage (PD), and personal injury (PI), which includes offenses such as libel, slander, false arrest, invasion of privacy, and others. The umbrella policy also fills some gaps in coverage over a specified deductible (often called a retained limit) in the underlying policy.
