What is the primary purpose of the coinsurance clause in property insurance policies?

The primary purpose of the coinsurance clause in property insurance policies is to encourage property owners to insure their property to its full value. This clause typically requires policyholders to insure their property for a specified percentage of its total value, often 80%, 90%, or 100%. If the insured value falls below this threshold, the insurer can reduce the claim payment in proportion to the amount of underinsurance.

By incentivizing policyholders to maintain adequate coverage, the coinsurance clause serves as a risk management tool for insurers. It helps to ensure that sufficient premiums are collected based on the true value of the insured property, reducing the likelihood of large losses for the insurer when claims arise. This mechanism ultimately protects both the insurance company and the insured by aligning their interests in maintaining adequate coverage. The other options, while related to aspects of insurance, do not capture the main intent of the coinsurance clause as effectively.
