The Board shall cause to be made an actuarial reevaluation of the rate of member contributions deducted from earnable compensation pursuant to subdivision 473(b)(2) of this title, on a periodic basis at least every three years, to determine whether the amount deducted is necessary to make the contributions picked up and paid by the State for such members cost neutral to the General Fund. The actuarial reevaluation shall consider all relevant factors, including federal tax law changes. The Board shall report the results of the actuarial reevaluation to the General Assembly together with any recommendations for adjustment in the members' contribution rate under subdivision 473(b)(2) of this title. The provisions of 2 V.S.A. § 20(d) (expiration of required reports) shall not apply to the report to be made under this section. (Added 1997, No. 68 (Adj. Sess.), § 8, eff.
