9.4 Business Income and Extra Expense

Key Takeaways

  • Business Income coverage (CP 00 30) pays lost net income plus continuing normal operating expenses, including payroll, during a covered suspension of operations.
  • The Period of Restoration begins 72 hours after the direct physical loss and ends when property should be repaired with reasonable speed — not when it actually is.
  • Civil Authority coverage pays up to 4 consecutive weeks when a government order bars access due to a covered loss at nearby property, after a 72-hour wait.
  • Business income coinsurance is based on 12 months of expected income; underinsuring triggers the limit-carried over limit-required penalty.
  • Extended Business Income continues coverage during the post-restoration ramp-up for a default of 60 days under current ISO editions.

What Business Income Coverage Pays

Business Income coverage (also called business interruption) is written on ISO form CP 00 30 (with extra expense) or CP 00 32 (without). It does not pay for the damaged property — that is the BPP's job — it pays the financial loss of being unable to operate after a covered cause of loss damages covered property.

Business Income = Net Income (profit or loss) that would have been earned + Continuing normal operating expenses, including payroll

Net incomePre-tax profit lost during shutdownLost sales margin
Continuing expensesCosts that go on despite closureRent, loan interest, key salaries
Ordinary payrollRank-and-file wagesClerks, line workers

Ordinary Payroll

"Ordinary payroll" means rank-and-file employees; officers, executives, department managers, and contract employees are not ordinary payroll. The insured may include it, exclude it, or limit it to a set number of days (often 60 or 90) to lower premium.

The Period of Restoration

  • Begins: 72 hours after the direct physical loss (a waiting period — income lost in those 72 hours is excluded).
  • Ends (the earlier of): the date property should be repaired or replaced with reasonable speed and similar quality, OR the date the business resumes at a new permanent location.

Critical rule: coverage ends when property should be repaired, not when it actually is. Foot-dragging on repairs is not covered.

Extra Expense

Extra Expense pays costs above normal operating expenses incurred to avoid or minimize the shutdown — temporary space, leased replacement equipment, overtime, expedited shipping. On a stand-alone Extra Expense policy (CP 00 50), every dollar spent should reduce the income loss, so it suits operations (data centers, dairies, newspapers) that must stay open.

Coinsurance and Duration

Business income coinsurance is based on 12 months of expected business income. The insured picks a percentage; falling short triggers a penalty.

50%Half~6-month exposure
70%Seven-tenths~8 months
80%Four-fifths~9 months
100%All~12 months
125%With buffer12+ months

Coinsurance Penalty Formula

Payment = Loss × (Limit Carried ÷ Limit Required)

Worked example: Annual business income is $1,000,000 and the insured chose 80 percent coinsurance, so the required limit is $800,000. The insured carried only $600,000. The recovery factor is $600,000 ÷ $800,000 = 75 percent. A $100,000 income loss pays only $75,000 (less any deductible); the $25,000 shortfall is the coinsurance penalty.

Other Built-In Coverages

Civil Authority

When a government order prohibits access to the insured premises because of a covered loss at a nearby property, the form pays lost income and extra expense. Coverage starts 72 hours after the order and lasts up to 4 consecutive weeks. A voluntary closure does not trigger it.

Extended Business Income

After property is restored and the business reopens, sales rarely snap back instantly. Extended Business Income continues coverage during the ramp-up until income returns to normal, up to a default of 60 days under current ISO editions.

Dependent Properties

Covers income loss when a property the insured depends on but does not own is damaged — a key supplier (contributing location), a major customer (recipient location), a manufacturing location, or an anchor store that draws traffic (leader location).

Indemnity Options and Net Income as a Loss

Instead of coinsurance, the insured may pick the Monthly Limit of Indemnity (caps payout per 30 days at 1/3, 1/4, or 1/6 of the limit) or the Maximum Period of Indemnity (drops coinsurance, pays up to 120 days).

"Net income" is the profit or loss the business would have earned. A seasonal business shut during its slow season recovers little because there was no profit to lose — only genuinely continuing expenses.

Common Traps

  • The 72-hour wait is a waiting period, not a dollar deductible.
  • Coverage tracks when repairs should be done, not actual delays.
  • Civil Authority requires a government order and a covered loss at a nearby property.
  • Extended Business Income default is 60 days; older notes saying 30 days are outdated.

Determining the Loss

Adjusters reconstruct the income the business would have generated absent the loss, using historical financial statements, the experience before the loss, and the probable experience had no loss occurred. The form expressly directs the insurer to consider seasonal trends and the likely continuation of the business. This is why accurate, current bookkeeping is the single best protection an insured can have for a business-income claim.

Stand-Alone Extra Expense Versus Combined

FormIncome loss?Extra expense?Best for
CP 00 30 Business Income and Extra ExpenseYesYesMost businesses
CP 00 32 Business Income without Extra ExpenseYesNoLower-cost option
CP 00 50 Extra Expense onlyNoYesMust-stay-open operations

An operation such as a newspaper, dairy, or data center loses customers permanently if it closes, so it buys Extra Expense only and spends to stay open; a typical retailer that can simply shut and reopen buys Business Income to replace lost profit.
