As the name implies, an umbrella liability policy provides coverage over and above your other liability coverages. It is designed to protect against unusually high losses, when the policy limits of one of the underlying policies have been used up. For the typical business, the umbrella policy would provide protection over and above general liability and auto liability policies. If you have Employment Practices Liability Insurance, Directors and Officers Liability, or other types of liability insurance, the umbrella could provide protection over and above those policy limits as well.
