W.S. 26-21-109(b) Wyoming Insurance Code requires that refund formulae be filed with and approved by the Commissioner. No refund formula may be utilized unless it is at least as favorable to the insured debtor as a formula providing a pro rata refund of premium. In no event need a refund or credit be made if the amount thereof is less than one dollar.
