Option A. The maximum retirement allowance payable under law for the life of the member. Upon the member's death, the member's designated beneficiary is entitled to receive any remaining member contributions.
Option B. A reduced retirement allowance payable during the retired member's life, which continues after the member's death for the life of the member's designated beneficiary or, if the member selects multiple beneficiaries, which continues after the member's death in equal shares to and for the life of each of two or more beneficiaries. The reduced retirement allowance payable under this option must be the actuarial equivalent of the maximum retirement allowance payable to the member under law, and if the member selects multiple beneficiaries, the benefit reduction factor must be based on the average age of the designated beneficiaries. If all of the designated beneficiaries predecease the member, then the member shall receive a retirement allowance equal to the maximum retirement allowance payable under law to the member. Any retirement allowance payable under this option, except an allowance for disability retirement pursuant to Section 9-11-80, shall be subject to the incidental death benefit limitation upon the payment of survivorship benefits to a nonspouse beneficiary under Section 401(a)(9)(G) of the Internal Revenue Code and Treasury Regulation Section 1.401(a)(9)-6, Q&A-2.
Option C. A reduced retirement allowance payable during the retired member's life, which continues after the member's death at one-half the rate paid to the member for the life of the member's designated beneficiary or, if the member selects multiple beneficiaries, which continues after the member's death at one-half the rate paid to the member in equal shares to and for the life of each of two or more beneficiaries. The reduced retirement allowance payable under this option must be the actuarial equivalent of the maximum retirement allowance payable to the member under law, and if the member selects multiple beneficiaries, the benefit reduction factor must be based on the average age of the designated beneficiaries. If all of the designated beneficiaries predecease the member, then the member shall receive a retirement allowance equal to the maximum retirement allowance payable under law to the member.
