Business interruption insurance is a form of insurance coverage that replaces business income lost as a result of an event that interrupts the operations of the business, such as fire or a natural disaster. Business interruption insurance is not sold as a separate policy, but is either added to a property/casualty policy or included in a comprehensive package policy.

​

Business interruption insurance coverage extends until the end of the business interruption period, as determined by the insurance policy. Most business interruption insurance policies define this period as starting on the date of the covered peril and the damaged property is physically repaired and returned to operations under the same condition that existed prior to the disaster.
