(1) Whenever a financed insurance contract is canceled by a person other than the insured, the insurer shall process cancellation of the financed insurance policy on a pro rata basis. The insurer shall return whatever gross unearned premiums are due under the insurance contract to the premium finance company for the account of the insured or insureds.
(2) If the crediting of the return premiums to the account of the insured results in a surplus over the amount due from the insured, the premium finance company shall refund the excess to the insured, except that a refund is not required if the excess amounts to less than $1.
