Coverage for loss of unearned premium if insured property is destroyed before the end of a policy period. The policyholder pays in advance for insurance, but the insurer does not earn the premium until coverage is provided. For example, if a policy period is one year, one-twelfth of the premium is earned each month. After six months, one-half of the premium is still unearned and belongs to the policyholder if the policy is canceled. If the property is destroyed in the second month and the insurer pays the claim, the policyholder would have nothing left to insure. Unearned premium insurance reimburses the insured for the part of the premium paid up front that is no longer needed for insurance coverage.
