§1985. Actuary

            A. The actuary shall be the technical advisor of the board on matters regarding the operation of the funds of the system.

            B. Immediately after the revision date and at least once every five years thereafter, the actuary shall make an actuarial investigation of the members as to mortality, disability, retirement, separation, marital status of employees, marriage of surviving spouses, interest, and employee earning rates.

            C. In addition to such other duties as the board shall prescribe, the actuary shall:

            (1) Recommend actuarial tables to be used for computing benefits and rate of contributions required of participating employers and members based on the investigation required by B, above.

            (2) Make an annual valuation of the liabilities and reserves for present and prospective annuities and benefits, and certify to the correctness thereof.

            (3) Review the terms of each new agreement as pertains to prior service, conduct such investigation as is necessary to determine the existing accrued liability, and recommend to the board the amount of employer contributions required to offset such liability.

            D.(1) Unless different actuarial assumptions are formally adopted and disclosed, as provided herein, the following assumptions shall determine the actuarial equivalents as used in this retirement system, subject to the provisions of Title 11 of the Louisiana Revised Statutes:

            (a) Interest shall be compounded annually at the rate of seven percent per annum; and

            (b) Annuity rates shall be determined on the basis of one hundred and ten percent of the 1971 Group Annuity Mortality Tables.

            (2) The board of trustees may authorize the use of interest and mortality rates in determining the actuarial equivalents which are different from the actuarial assumptions used for other purposes hereunder. Any change in such actuarial assumptions shall be considered a part of this retirement system and shall be considered an amendment to the provisions of this Section. In order to be effective, such change shall be formally adopted by the board of trustees and disclosed to members of the retirement system.
