Business Interruption Insurance
Business Interruption Insurance is also known as Business Income Coverage. This is a form of insurance that covers income the business loses in the event the business sustains property damage.
Usually, the policy covers the period of time it takes to get the business up and running again. It may be extended past that period though (it'd have to be written into the policy).
There are two kinds: business income, no extra expense, and business income, plus extra expense. The extra expense refers to any expenses over the normal income (for instance, if the business had a hugely profitable event scheduled and had to cancel due to lost property).
