Any such amounts so appropriated shall be credited to a special fund to be known as the Post Retirement Insurance Liability Fund. Any interest or other income earned by such fund shall be added to and become a part of the fund. The Lexington contributory retirement board shall be the custodian of such fund and may invest the monies held in the fund in accordance with the rules and regulations of the public employees retirement administration commission and in accordance with any applicable general law.
