What main function does the coinsurance provision serve in property insurance?

The coinsurance provision in property insurance serves the crucial function of ensuring that properties are insured for their full value. This provision typically requires the insured to carry insurance coverage equal to a specified percentage of the property's total value (commonly 80%, 90%, or 100%). If the insured does not meet this requirement and suffers a loss, the coinsurance clause will result in a penalty, reducing the amount of the claim payout in proportion to the amount of coverage actually carried compared to the amount that should have been carried.

By requiring policyholders to insure their properties near their actual value, the coinsurance provision helps to protect both the insurer and the insured. It minimizes the risk of underinsurance, which can lead to significant losses for the insured in the event of a claim. It also helps insurers maintain overall premium pricing and risk management, ensuring that claim payouts remain sustainable.

Other options presented do not accurately capture the primary role of coinsurance. Adjusting coverage limits annually pertains more to inflation guard features in policies rather than coinsurance. Eliminating the deductible is not a function of coinsurance; rather, deductibles are a separate aspect of a policy that determines how much the policyholder must pay out of pocket before the insurer pays a claim.
