The actuarial valuation required by § 3-12C-226 , must be based on actuarial assumptions adopted by the board, as a result of an actuarial experience analysis. The board may not make any change in the actuarial assumptions unless the approved actuary retained to make the actuarial valuation certifies that the change is reasonable. If the board makes a change, the board must report the change to the Governor and to the Retirement Laws Committee. The report must include the actuary's and board's analysis of the conditions that led to the change.
