Amendment of provisions of retirement system

A. The provisions of the retirement system may be amended by action of the legislature in the same manner as any other statute may be amended by the legislature. In addition, action by the board of trustees with respect to the payment of cost-of living adjustments, with respect to the payment of employee contributions, with respect to actuarial assumptions, and with respect to other actions authorized in this Chapter shall be considered amendments to the provisions of the retirement system. B. No amendment to the retirement system shall operate to deprive any member of a benefit to which he is entitled. In the case of any merger or consolidation with or transfer of assets or liabilities to any other retirement system, each member in the retirement system shall, if the retirement system is then terminated, receive a benefit immediately after the merger, consolidation, or transfer which is equal to or greater than the benefit he would have been entitled to receive immediately before the merger, consolidation, or transfer if the retirement system had then terminated. C. Upon the termination or partial termination of the retirement system, the board of trustees shall reevaluate and redetermine the benefit of each member, and the entire benefit of each member may be paid or commence to be paid and distributed to such member, or if he dies before such distribution, to the beneficiary or beneficiaries designated by the member. However, if the member is still employed and the system is partially terminated, payment shall not be made until retirement or termination and shall be held until payment is otherwise due under the provisions of the retirement system. A member's right to his benefit is not conditioned upon a sufficiency of assets in the event of termination. D. Upon termination or partial termination of the retirement system, a member's interest in the system shall be nonforfeitable to the extent funded. E. The retirement system is intended to qualify under 26 U.S.C. 401(a). Accordingly, any amendments to the provisions of the retirement system shall be designed to maintain this qualification.
