Property & Casualty Insurance Exam (National Portion)Property and Casualty Insurance BasicsMedium

A business owner has a Commercial Property policy with a 80% coinsurance clause. The building is valued at $500,000. To avoid a coinsurance penalty, what minimum amount of insurance must the owner carry?

  1. A$400,000
  2. B$300,000
  3. C$625,000
  4. D$500,000
Show answer & explanation

Correct answer: A. $400,000

To avoid a coinsurance penalty, the insured must carry coverage equal to or greater than the coinsurance percentage multiplied by the property's value. In this case, 80% of $500,000 is $400,000. ($500,000 * 0.80 = $400,000).

Why the other options are wrong

  • B. This is 60% of the value, which is less than required.
  • C. This is 125% of the value, calculated incorrectly or as if it were a different clause.
  • D. This is 100% of the value, which is more than required but avoids penalty.

Coinsurance Clause (Property)

A provision that requires the insured to carry a certain percentage of the property's value in insurance coverage to receive full payment for a partial loss.

  • Discourages underinsurance.
  • If underinsured, a penalty applies to partial losses.
  • Common percentages are 80%, 90%, or 100%.

Memory trick: Coinsurance: 'Co-insure' yourself for the 'Co-rrect' amount.
