9.4 Business Income and Extra Expense

Insuring the income, not just the building

When a covered physical loss shuts down operations, the building policy rebuilds the structure but does nothing for lost revenue. Business Income (and Extra Expense) Coverage Form, ISO CP 00 30, fills that gap. (A variant, CP 00 32, covers Business Income without Extra Expense.)

Business Income is defined as net income (profit or loss) that would have been earned, plus continuing normal operating expenses including payroll. Coverage begins when the period of restoration starts and ends when the property should be repaired with reasonable speed — not when the insured actually finishes.

Period of restoration, waiting period, and Extra Expense

Key timing rules tested heavily:

• Period of restoration starts 72 hours after the physical loss (the standard waiting period) and ends at the earlier of (a) when property is repaired/replaced with reasonable speed and quality, or (b) when business resumes at a new permanent location.
• Extended Business Income continues coverage after operations resume (default 30 days, extendable) while revenue ramps back to normal.
• Extra Expense pays the extra costs to avoid or minimize the shutdown — renting temporary space, expediting repairs, leasing equipment.

Business Income can be written with a Coinsurance clause (often 50%–125% of annual BI) or instead with the Agreed Value, Maximum Period of Indemnity, or Monthly Limit of Indemnity options that suspend coinsurance.

Worked Business Income calculation

A covered fire closes a retail store. The insured proves the following 4-month restoration period figures:

• Net income that would have been earned: $80,000
• Continuing normal operating expenses (rent, key payroll): $50,000
• Non-continuing expenses saved (hourly wages, supplies not bought): $20,000
• Extra Expense to rent temporary space and reopen early: $15,000

Business Income loss = net income + continuing expenses = $80,000 + $50,000 = $130,000 (expenses that did NOT continue are not paid). Add Extra Expense of $15,000 (paid because it reduced the BI loss). Total claim = $145,000, subject to the limit and any coinsurance test.

Trap: non-continuing expenses are subtracted from the recovery — the policy restores the insured to the position they would have occupied, not better.

The non-coinsurance options and key additional coverages

Because estimating a year's income is hard, ISO offers three ways to suspend the Business Income coinsurance clause; the exam tests when each fits:

• Maximum Period of Indemnity — caps recovery at the lesser of the actual loss during 120 days or the policy limit; no coinsurance applies. Best for short, predictable shutdowns.
• Monthly Limit of Indemnity — pays a stated fraction (1/3, 1/4, or 1/6) of the limit per month; no coinsurance. Suits seasonal or uncertain restoration periods.
• Agreed Value — insured files a Business Income Report/Worksheet; insurer agrees to a value and waives coinsurance for the term.

The form also bundles Additional Coverages: Civil Authority (loss when a government order denies access to the premises because of damage to nearby property — coverage begins 72 hours after the order and runs up to 4 weeks), Alterations and New Buildings (income loss delayed by damage to property under construction), and Extended Business Income (default 30 days after reopening).

A common scenario: a fire across the street prompts the fire marshal to close the block; the insured's own building is undamaged. Direct BI does not respond — but Civil Authority does, after the 72-hour wait, for up to four weeks. Distinguishing Civil Authority from ordinary Business Income is a recurring exam item.

Business Income, Extra Expense, and the Period of Restoration

Time-element coverage insures the indirect loss that follows a direct physical loss. The Business Income (and Extra Expense) Coverage Form (CP 00 30) pays the net income (net profit plus continuing normal operating expenses, including payroll) the insured would have earned, plus extra expense to speed resumption, during the period of restoration. That period begins 72 hours after the direct physical loss (the waiting period) and ends when the property should be repaired with reasonable speed — not when the insured chooses to reopen.

The Extended Business Income additional coverage continues payments for a limited time (often 30–60 days) after operations resume while revenue rebuilds to normal. Business income forms use a coinsurance percentage based on 12 months of projected income, but insureds frequently elect the Monthly Limit of Indemnity, Maximum Period of Indemnity, or Agreed Value options to suspend coinsurance. Civil authority coverage extends business income when a government order prevents access to the premises because of nearby covered damage, typically for up to four weeks.

Worked Business-Income and Extra-Expense Distinction

A common exam item separates the two coverages. Business income replaces lost earnings while the operation is shut down or slowed; extra expense pays the additional cost to avoid or minimize a shutdown — renting temporary space, leasing equipment, or paying overtime. A bakery whose oven is destroyed might claim business income for the profit lost while closed, and extra expense for the cost of baking at a rented kitchen to keep customers.

Extra Expense-only coverage (CP 00 50) suits businesses such as newspapers or data centers that must stay operational at almost any cost, where preventing the income loss matters more than reimbursing it.
