Wyo. Stat. § 26-19-105: Readjustment of premiums; dividends.

Any group disability insurance contract may provide for the readjustment of the rate of premium based upon the experience under the contract. If a policy dividend is declared or a reduction in rate is made or continued for the first or any subsequent year of insurance under any group disability insurance policy issued to any policyholder, the excess, if any, of the aggregate dividends or rate reductions under the policy and all other group insurance policies of the policyholder over the aggregate expenditure for insurance under those policies made from funds contributed by the policyholder, or by an employer of insured persons, or by a union or association to which the insured persons belong, including expenditures made in connection with administration of the policies, shall be applied by the policyholder for the sole benefit of insured employees or members.
