The Coinsurance Trap and the Three-Day Street Closure
Vance Precision Machining has a commercial package policy with a Building and Personal Property form: building $1,400,000 (adequate), business personal property $600,000, 80% coinsurance, $2,500 deductible. Business income coverage carries a $1,000,000 limit, a 72-hour waiting period, and 30 days of extended business income. An appraiser valued the building and BPP at $1,850,000 combined, of which BPP replacement cost is $850,000. In June an electrical arc from a forklift charger ignites packing material; fire destroys $200,000 of BPP and shuts the plant for 43 days. Net income plus continuing expenses run $180,000 per month. A separate fire two blocks away later causes the city to close the street for three days; Vance's building is untouched.
1. Compute the property payment and explain the coinsurance mechanics.
Read the worked answer
Coinsurance is tested separately for building and BPP. The building is adequately insured, so ignore it. Test the BPP.
Step 1 - the required limit. 80% x $850,000 replacement cost = $680,000 required.
Step 2 - the ratio actually carried. $600,000 / $680,000 = 0.88235
Step 3 - apply the ratio to the loss. 0.88235 x $200,000 = $176,470.59
Step 4 - apply the deductible. $176,470.59 - $2,500 = $173,970.59 payable.
Out of pocket: $200,000 - $173,970.59 = $26,029.41 - of which $23,529.41 is pure coinsurance penalty and $2,500 is the deductible.
The judgment point. Had Vance carried the required $680,000, the loss would have paid $197,500 and the total out of pocket would have been just the deductible. The extra $80,000 of limit costs a fraction of the $23,529 penalty. This is the conversation to have at every renewal: the coinsurance clause is a penalty for insuring to budget rather than to value. Note the test uses the same valuation basis as the loss settlement - replacement cost here - so a stale appraisal is itself a coverage hazard.
2. Compute the business income payment for the 43-day shutdown and explain what the waiting period does.

Business income pays net income plus continuing normal operating expenses for the period of restoration, after the waiting period.
Step 1 - strip the waiting period. The period of restoration ran 43 days. The 72-hour waiting period means the policy pays nothing for the first three days: 43 - 3 = 40 compensable days.
Step 2 - daily rate. $180,000 per month / 30 = $6,000 per day.
Step 3 - the payment. 40 x $6,000 = $240,000.
This amount is well inside the $1,000,000 limit.
Three things adjusters get wrong here:
- Do not deduct the property deductible from the BI loss. BI has its own waiting period, which functions as its deductible. Charging the $2,500 again is a double hit.
- Extended business income is separate. After the plant is repaired, the 30-day extension pays for the ramp-up period while sales have not returned to normal - it is not part of the 40 days and should be tracked on its own.
- Extra expense is a different bucket. If Vance rented a temporary machining cell to keep a key customer, that is paid in addition, and it is not reduced by whether business income was earned.
Verify before paying: whether this form's business income coverage carries its own coinsurance condition. Many package forms use actual-loss-sustained with no coinsurance; others impose 50/80/100% of annual gross profits. If it does apply, run the same ratio test as the property loss.
3. Is the three-day street closure covered, and is the lost contract with a departing customer covered?
Read the worked answer
The street closure - civil authority, and probably $0. Civil authority coverage requires all of these: a covered cause of loss damages property other than the insured's; the action of a civil authority prohibits access to the insured premises; and the closure is the direct result. The two-block fire qualifies on the first two elements.
The obstacle is the waiting period. The standard form applies the 72-hour waiting period to civil authority loss, so a three-day closure produces almost no payable loss - at best a fraction of one day, and only if the closure ran beyond 72 hours. Confirm the exact dates and hours; then issue a documented no-pay rather than a denial, since the coverage was triggered but the waiting period swallowed it. The ISO form caps civil authority at four weeks, so a longer closure would have paid.
The departing customer - likely not covered, or covered only briefly. Business income measures the net income the business would have earned during the period of restoration. If a customer permanently moves its work because of the fire, that is a market-share loss that persists after the plant is rebuilt. Extended business income pays for up to 30 days of the ramp-up, and only for income that would have been earned but for the fire. It does not fund a permanently lost account.
The examiner's angle: civil authority, extended business income, and consequential loss are three different doors. Walk through each one and reject it on its own rule rather than saying "no BI" in one sentence.
