Option 1. If he dies before he has received in annuity payment the value of the member's annuity savings account as it was at the time of his retirement, the balance shall be paid to his legal representative or to such person as he shall nominate by written designation duly acknowledged and filed with the board; or
Option 2. Upon his death, his reduced retirement allowance shall be continued throughout the life of, and paid to, such person as he has nominated by written designation duly acknowledged and filed with the board of trustees at the time of his retirement;
Option 3. Upon his death, one-half (1/2) of his reduced retirement allowance shall be continued throughout the life of, and paid to, such person as he shall have nominated by written designation duly acknowledged and filed with the board of trustees at the time of his retirement, and the other one-half (1/2) of his reduced retirement allowance to some other designated beneficiary;
Option 4. Upon his death, three-fourths (3/4) of his reduced retirement allowance, or such other specified amount, shall be continued throughout the life of, and paid to, such person he shall have nominated by written designation duly acknowledged and filed with the board of trustees at the time of his retirement;
Option 4-A. Upon his death, one-half (1/2) of his reduced retirement allowance, or such other specified amount, shall be continued throughout the life of, and paid to, such person as he shall have nominated by written designation duly acknowledged and filed with the board of trustees at the time of his retirement; or
Option 4-B. A reduced retirement allowance shall be continued throughout the life of the retirant, but with the further guarantee of payments to the named beneficiary or beneficiaries for a specified number of years certain. If the retired member or the last designated beneficiary both die prior to receiving all guaranteed payments due, the actuarial equivalent of the remaining payments shall be paid to the successors of the retired member under Section 25-13-21.1(1);
Option 4-C. Such retirement allowance otherwise payable may be converted into a retirement allowance of equivalent actuarial value in such an amount that, with the member's benefit under Title II of the federal Social Security Act, the member will receive, so far as possible, approximately the same amount annually before and after the earliest age at which the member becomes eligible to receive a social security benefit. This option shall not be available to retirees whose retirement is effective on or after July 1, 2004;
Option 6. Any member who is eligible to retire with an unreduced benefit may select the maximum retirement benefit or an optional benefit as provided in this subsection together with a partial lump-sum distribution. The amount of the lump-sum distribution under this option shall be equal to the maximum monthly benefit multiplied by twelve (12), twenty-four (24) or thirty-six (36) as selected by the member. The maximum retirement benefit shall be actuarially reduced to reflect the amount of the lump-sum distribution selected and further reduced for any other optional benefit selected. The annuity and lump-sum distribution shall be computed to result in no actuarial loss to the system. The lump-sum distribution shall be made as a single payment payable at the time the first monthly annuity payment is paid to the retiree. The amount of the lump-sum distribution shall be deducted from the member's annuity savings account in computing what contributions remain at the death of the retiree and/or a beneficiary. The lump-sum distribution option may be elected only once by a member upon initial retirement, and may not be elected by a retiree, by members applying for a disability retirement annuity, by survivors or by a member selecting Option 4-C.
