The 80% Clause and the Underinsured Bakery
Rosa Ibarra owns Pan Dulce Ibarra, a bakery in a 60-year-old building. Her commercial property policy carries a $720,000 building limit, an 80% coinsurance clause, replacement cost valuation, and a $10,000 deductible. When the policy was written, the broker's inspection estimated replacement cost at $750,000. Eight months later, after a kitchen remodel and a sharp rise in construction costs, an independent appraisal puts replacement cost at $1,200,000. A proofing-oven wiring fault starts a fire; the adjuster's repair estimate is $300,000, and $40,000 of that is work required to bring the electrical system up to current code. The policy contains no ordinance-or-law coverage. First National Bank holds a mortgage on the building.

Step 1 - Covered loss. The $40,000 code-upgrade cost is excluded (no ordinance-or-law coverage). Covered loss = $300,000 − $40,000 = $260,000.
Step 2 - Coinsurance requirement. 80% × $1,200,000 (replacement cost at time of loss) = $960,000 required.
Step 3 - Ratio. Limit carried ÷ required = $720,000 ÷ $960,000 = 0.75.
Step 4 - Apply. $260,000 × 0.75 = $195,000.
Step 5 - Deductible. $195,000 − $10,000 = $185,000 payable.
Penalty quantified: absent the coinsurance clause, the insured would have collected $260,000 − $10,000 = $250,000. The penalty costs her $55,000 on this loss. Note also that the excluded code work is a separate $40,000 out of pocket, so her total unrecovered amount is $95,000.
Document the valuation appraisal, the exclusion analysis for the code work, and the calculation worksheet in the file; insureds routinely dispute coinsurance math, and a step-by-step worksheet is the best defense.
2. Rosa's agent argues that the broker's original $750,000 replacement-cost estimate proves the limit was adequate and the penalty should be waived. How should the adjuster respond?

The argument fails on the policy language, but it should be handled carefully.
- Coinsurance is measured at the time of loss, using the actual replacement cost then, not the estimate used at inception. A stale or low estimate does not rewrite the clause. The clause exists precisely to make the insured share the risk of underinsurance.
- Waiver requires authority. An adjuster cannot voluntarily waive a policy condition; doing so can itself be a breach of the adjuster's duty to the insurer and may create inconsistent treatment across claims.
- Explain in writing. Send the worksheet, the appraisal, and the policy language, and note what limit ($960,000) would have produced full recovery. This converts a dispute into a documented explanation.
- Do not opine on the agent's or broker's liability. If Rosa raises errors-and-omissions exposure, the adjuster acknowledges the concern, states that coverage is determined by the policy as written, and refers the matter to the carrier's procedures. The adjuster should not advise her about suing her broker.
- Consider a policy review offer at renewal as a service step - but never as a promise of payment.
Genuine ambiguity in the clause, or a carrier-issued valuation that the insured reasonably relied on, is a different matter and should be escalated to management rather than decided unilaterally.
3. How does First National Bank's mortgage clause affect the payment, and can the coinsurance penalty be applied to the bank's share?
Read the worked answer
The mortgage clause creates a separate contractual interest, so the bank is paid to the extent of its interest even where the insured's own conduct might otherwise defeat coverage.
- Loss payable mechanics: obtain the current loan payoff, issue the draft jointly or as their interests appear, and confirm whether the mortgage clause is a simple loss-payable or a full standard mortgage clause (the latter gives the lender its own right to notice, to pay premium, and to receive loss proceeds).
- Coinsurance travels with the policy. The total payable on the loss is $185,000. The mortgage clause protects the lender from the insured's acts and neglect; it does not create a separate, larger limit or exempt the loss from valuation provisions. So the bank's recovery comes out of the same $185,000, capped by the unpaid principal balance.
- Practical effect: if the loan balance exceeds $185,000, the bank receives the entire draft (or its balance), and Rosa receives only the excess - which may leave the building unrepaired and the loan in default.
- Next step: notify the bank in writing of the loss, the computed amount, and the coinsurance reduction, and advise Rosa that repair funds may be less than the cost of repair.
