Stat. Ann. § 74-49b14, and amendments thereto.

(b) Any amount of an employee’s salary or compensation that is deferred on a pre-tax basis under an authorized participation agreement shall continue to be included as regular compensation for all purposes of computing retirement and pension benefits earned by such employee.
