9.4 Business Income and Extra Expense

Key Takeaways

  • Business Income coverage (CP 00 30) pays lost net income plus continuing normal operating expenses caused by a covered suspension of operations.
  • The Period of Restoration begins 72 hours after the direct physical loss and ends when the property should be repaired with reasonable speed, not when it actually is.
  • Civil Authority coverage pays up to 4 consecutive weeks after a 72-hour wait when a government order bars access due to a covered loss at nearby property.
  • Extended Business Income continues coverage during the post-restoration ramp-up for a default of 60 days under current ISO editions.
  • Extra Expense pays the added costs of staying open; on a stand-alone Extra Expense form (CP 00 50) those costs reduce or avoid the income loss.

What Business Income 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

ComponentMeaningExamples
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

The Period of Restoration is the window during which lost income is paid.

  • Begins: 72 hours after the time of direct physical loss - a waiting period, not a deductible, so income lost in those 72 hours is not recoverable.
  • Ends (the earlier of): the date the property should be repaired, rebuilt, or replaced with reasonable speed and similar quality, OR the date the business resumes at a new permanent location.

Critical rule: coverage ends when the property should be repaired, not when it actually is. Dragging out repairs leaves the extra downtime uncovered.

Extra Expense

Extra Expense pays costs above normal operating expenses incurred to avoid or minimize the shutdown - temporary space, leased 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 that must stay open such as data centers and newspapers.

Coinsurance and Duration

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

Coinsurance %Insure this share of 12-month incomeLoosely supports
50%Half~6 months
70%Seven-tenths~8 months
80%Four-fifths~9 months
100%All~12 months
125%With buffer12-plus months

Coinsurance Penalty Formula

Payment = Loss times (Limit Carried divided by 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 divided by $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.

Extended Business Income

After repairs finish 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 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).

Monthly Limit of Indemnity and Maximum Period

Instead of coinsurance, the insured may choose the Monthly Limit of Indemnity option, which caps the most payable in any 30-day period at a fraction (1/3, 1/4, or 1/6) of the limit and drops the coinsurance clause. The Maximum Period of Indemnity option also drops coinsurance and pays for a maximum of 120 days, suited to small operations expected to recover quickly.

Net Income Can Be a Loss

"Net income" is the profit or loss the business would have earned. A seasonal shop closed in its slow season, when it normally loses money, recovers little beyond genuinely continuing expenses; a retailer closed during peak holiday weeks recovers the large profit it provably would have made. Adjusters reconstruct expected income from historical statements and seasonal trend, which is why current bookkeeping is an insured's best protection.

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 needs a covered loss at a nearby property and a government order; a voluntary closure does not trigger it.
  • Extended Business Income default is 60 days under current editions - older notes saying 30 days are out of date.
  • Net income can be a loss; a business with no expected profit recovers only continuing expenses.
