Business income
Property coverage that replaces net income and continuing operating expenses, including payroll, while a covered physical loss suspends operations.
Also called: business interruption, BI, business interruption insurance, business income coverage
Business income coverage, also called business interruption, pays what a business loses when a covered physical loss shuts it down or slows it. In the ISO CP 00 30 form, business income is the net income (net profit or loss before income taxes) that would have been earned, plus continuing normal operating expenses, including payroll. It runs through the period of restoration, after a 72-hour waiting period, and the form adds extended business income to cover the ramp-up after you reopen.
Say a bakery earns $20,000 a month in net income and carries $50,000 a month in rent, payroll, loan payments and utilities that continue. A three-month closure after a fire produces roughly $210,000 of covered loss, minus the waiting period. A limit chosen from last year's profit alone would fall far short of that.
The trigger is direct physical loss or damage at the described premises from a covered cause of loss. A shutdown without physical damage, such as an order closing your street or a supplier's fire, needs civil authority or contingent business income coverage. Coinsurance, if shown in the declarations, is tested against a 12-month figure of net income plus operating expenses. extra expense covers the added cost of staying open. The guide on business interruption insurance: how business income coverage works explains the form, and the business income (interruption) limit calculator estimates a limit.
