Coinsurance and the Hurricane Deductible After Ida
A surplus lines commercial property policy covers a 40,000-square-foot warehouse in Orleans Parish. Replacement cost is $6,000,000. The policy limit is $4,000,000; the coinsurance percentage is 80%; the hurricane deductible is 5% of the building limit; there is no other insurance. In September 2021, Hurricane Ida causes $2,000,000 of covered building damage. The policy's coinsurance clause states that if the limit is less than the required limit, payment is reduced in the proportion that the limit bears to the required limit, and the hurricane deductible applies to the loss before the coinsurance percentage. The insured asks the broker why it will not receive $2,000,000. The insured also argues that the 5% hurricane deductible should be 5% of the $2,000,000 loss, or $100,000.

First calculate the required limit: 80% x $6,000,000 = $4,800,000. The carried limit is $4,000,000, so the coinsurance ratio is $4,000,000 / $4,800,000 = 0.833333. The hurricane deductible is 5% of the building limit: 5% x $4,000,000 = $200,000. Because the policy applies the deductible before the coinsurance percentage, subtract the deductible from the loss: $2,000,000 - $200,000 = $1,800,000. Apply the ratio: $1,800,000 x 0.833333 = $1,500,000. The insured receives $1,500,000, not $2,000,000. The unpaid $500,000 is the coinsurance penalty, and the $200,000 deductible is separate. If the policy had applied coinsurance before the deductible, the result would be different, which is why the exact clause wording matters.
2. How would the payment change if the insured had carried the required $4,800,000 limit? What should the broker have recommended?

If the limit had been $4,800,000, the coinsurance ratio would be 1.0. The deductible would be 5% x $4,800,000 = $240,000, and the payment would be $2,000,000 - $240,000 = $1,760,000. Increasing the limit raises the deductible because the deductible is tied to the building limit, but it eliminates the coinsurance penalty and produces a larger recovery. The broker should have compared the replacement cost value with the limit at placement and explained that an 80% coinsurance clause effectively requires at least $4,800,000 to avoid a penalty. If the insured chose a lower limit to save premium, the broker should document that the insured rejected a higher limit and understood the coinsurance exposure. A failure to explain that trade-off is a common E&O allegation.
3. Is the insured correct that the hurricane deductible should be $100,000? Explain how percentage deductibles work and how the broker should respond.
Read the worked answer
The insured is incorrect if the policy defines the hurricane deductible as 5% of the building limit. Percentage deductibles are usually applied to a value stated in the policy, such as the dwelling or building limit, not to the loss amount. Here 5% of $4,000,000 is $200,000. If the policy instead said 5% of the loss, the deductible would be $100,000, but that is not the language presented. The broker should show the insured the deductible provision, the declarations page, and the hurricane deductible endorsement, and explain that the deductible applies before the coinsurance calculation under this policy. The broker should also avoid describing the deductible as simply 5% without identifying the base, because that ambiguity is exactly what generates coverage complaints and E&O claims after a named storm.
