What is co-insurance primarily associated with?

Co-insurance is primarily associated with the concept of mandatory insurance coverage level for full claims payments. In property insurance, co-insurance is a clause that requires the policyholder to insure their property for a specified percentage of its total value to ensure that claims are fully paid.

If the property is not insured for at least that percentage, the insurance company will reduce the amount of the claim payment in proportion to the underinsurance. This means that for a policyholder to receive the full amount of a claim, they must adhere to the co-insurance requirement, which typically dictates that they maintain coverage equal to a certain percentage of the property's value. This encourages responsible underwriting and ensures that policyholders are adequately covered against potential risks.

The other options relate to different aspects of insurance but do not capture the essential principle of co-insurance as it pertains to maintaining a specific level of coverage to receive full claim payments.
