The Coinsurance Trap: A Deliberately Undervalued Plant and a $500,000 Fire
Hawk Electronics owns a 40,000-square-foot plant in Columbus, Indiana. Its commercial property policy shows a $1,500,000 building limit on a replacement-cost basis, an 80% coinsurance clause, a $10,000 deductible, no agreed value option, and no blanket or reporting form. At the last renewal the agent estimated replacement cost at $2,400,000; the owner deliberately insured for less to cut premium, saying his worst loss is nowhere near $1.5 million. In March a fire damages the building. Replacement cost of the damaged portion is $500,000, and depreciation attributable to that portion is $120,000. The insured also incurs $8,000 of debris removal and learns the township will require a $25,000 electrical and sprinkler upgrade before the building may be reoccupied. Both the adjuster and the insured believe the full $500,000 should be paid.
1. Compute what the carrier owes for the March fire, showing each step, and state your assumption about the order in which the coinsurance factor and the deductible are applied.

Step 1 - the requirement. 80% x $2,400,000 replacement cost = $1,920,000 needed to escape the penalty.
Step 2 - did he carry it? $1,500,000 carried against $1,920,000 required - a shortfall; he carried only 78.125% of the requirement.
Step 3 - coinsurance fraction. $1,500,000 / $1,920,000 = 0.78125
Step 4 - apply to the loss. 0.78125 x $500,000 = $390,625
Step 5 - deductible. $390,625 - $10,000 = $380,625 payable.
Assumption: the coinsurance factor is applied to the loss and the deductible subtracted afterward. If this edition applies the deductible first, the result is 0.78125 x $490,000 = $382,812.50. The $2,187.50 gap exists because the insured is his own coinsurer for 21.875% of the deductible. Read the order of conditions in the actual form.
Two further points. Replacement cost means the $120,000 depreciation is not deducted, but a holdback applies until repairs are actually completed; and $390,625 is well inside the limit, so the limit does not cap the payment.
2. The insured argues that because his $500,000 loss is far below his $1,500,000 limit, no penalty should apply. Explain the error and identify the changes that would remove the penalty.

The error. Coinsurance ties the limit to the value at risk, not to the size of the loss. The insured promised to carry at least 80% of replacement cost in exchange for a lower rate. By insuring to 78.125% of that requirement, he became a coinsurer of every loss - here 21.875%, or $109,375. The clause does not respond to how big the fire was; it responds to how much insurance was bought against what should have been bought.
Ways to fix it:
- Raise the limit to $1,920,000 and re-verify values at every renewal - construction costs have been rising faster than most schedules of values.
- Agreed Value option: the carrier accepts a current statement of values and suspends the coinsurance condition for the policy period. It removes the penalty but does not protect against a materially misrepresented value - and the insured usually must sign a values report.
- Reporting form: provisional premium with periodic reports of values; the premium trues up and the underinsurance problem becomes an ongoing administrative task rather than a claim-time penalty.
- Blanket limit across multiple locations, if he had them - it helps with uneven values between buildings but does not cure an overall undervaluation.
Telling the insured the truth matters: the $109,375 penalty is roughly the premium he saved by carrying $420,000 less insurance.
3. How should the carrier treat the $8,000 debris removal and the $25,000 code-required upgrade?
Read the worked answer
Debris removal. In the standard commercial property form this is a coverage extension, typically payable in addition to the limit of insurance, capped at 25% of the amount paid for the direct physical loss plus any remaining limit. At $8,000 against a $390,625 loss payment, it is comfortably inside the cap and does not erode the building limit. The adjuster should confirm the extension language rather than assume.
Ordinance or law. The $25,000 upgrade is not physical damage; it is increased cost to comply with code. Enforcement of an ordinance that raises the cost of repair or reconstruction is excluded unless the Ordinance or Law endorsement is attached, and that endorsement is usually written in three parts: coverage for the undamaged portion of the building, demolition cost, and increased cost of construction. Nothing in the facts says it was attached.
Conclusion. Pay the debris removal as an additional amount; disclaim the code upgrade but verify the declarations and endorsement schedule first, and explain to the insured what buying the ordinance-or-law endorsement would have done. The deductible applies once per occurrence, not once per coverage item.
