California Code, Government Code - GOV § 53205.1

(a) From funds under its jurisdiction, the legislative body may authorize payment of all or any portion as it may elect of the premiums, dues, or other charges for health and welfare benefits on the spouse and dependent children under the age of 21, dependent children under the age of 25 who are full-time students at a college or university, and dependent children regardless of age who are physically or mentally incapacitated, of those officers and employees, including retired officers and employees, subject to the jurisdiction and for whom those health and welfare benefits have been provided.

(b) Those expenditures are charges against the funds. If the employer pays any portion of the premiums for that insurance, any dividend paid or premiums refunded under any such insurance up to the aggregate expenditures of the employer for that insurance are the employer's property. The excess, if any, shall be applied by the employer for the benefit of insured employees or their dependents generally.
