(1) A member may elect to have such member’s retirement benefit paid under one of the options provided in this section in lieu of having it paid in the form stated in subsections (1) and (2) of Kan. Stat. Ann. § 74-4958, and amendments thereto. Such election must be made before the date of actual retirement. Only a specific individual person may be designated as a joint annuitant at the time of election of the joint and 1/2 to joint annuitant survivor option, the joint and survivor option and the joint and 3/4 to joint annuitant survivor option. Except as specifically provided in this subsection, an option elected by a member as provided in this section shall not be changed or canceled nor shall the named joint annuitant be changed after the date of actual retirement of the member. If a retirant is divorced after the retirant’s date of actual retirement, and the retirant has named the retirant’s ex-spouse as a joint annuitant under subsection (5), the joint annuitant option may be canceled and the retirant’s benefit returned to the maximum amount of such retirant’s retirement benefit commencing the first month following the date such cancellation is ordered by the district court of the county where the divorce action was filed. The retirant shall not receive a refund or interest of any amounts already paid to fund the original joint annuitant benefit. The retirant may not name a subsequent joint annuitant once the original joint annuitant option has been canceled.

(2) The amount of a retirement benefit payable under an option shall be based on the age of the member and, if applicable, the age of the joint annuitant, and shall be such amount as to be the actuarial equivalent of the retirement benefit otherwise payable under subsections (1) or (2) of Kan. Stat. Ann. § 74-4958, and amendments thereto, as prescribed under subsection (5). In no case shall the total amount of retirement benefit paid under any option provided in this section be more than 100% of the retirement benefit which would have been otherwise payable if no option had been elected under this section.

(3) If a member who was, up to the entry date of such member’s employer, covered by a pension system under the provisions of Kan. Stat. Ann. §§ 13-14a01 to 13-14a14, inclusive, or 14-10a01 to 14-10a15, inclusive, and amendments thereto, so elects one of the options under this section, payment of such option shall be in lieu of any payments provided in subsection (3) of Kan. Stat. Ann. § 74-4958, and amendments thereto.

(4) Such election of an option shall become null and void upon the death of a member prior to such member’s retirement, except that if a member, who is eligible to retire in accordance with the provisions of subsections (1) and (2) of Kan. Stat. Ann. § 74-4958, and amendments thereto, dies without having actually retired the member’s spouse, if the spouse is beneficiary for the member’s accumulated contributions, and no benefits are payable under subsections (1) and (2) of Kan. Stat. Ann. § 74-4959, and amendments thereto, may elect to receive benefits under one of the options provided in this section, in lieu of receiving the member’s accumulated contributions.

(5) The following retirement options which are subject to the provisions of Kan. Stat. Ann. § 74-49,123, and amendments thereto, are available:

(A) Joint and 1/2 to joint annuitant survivor. A reduced retirement benefit is payable to the retirant during the retirant’s lifetime in a monthly amount equal to the product of (A) the monthly payment of the retirement annuity otherwise payable under Kan. Stat. Ann. § 74-4958, and amendments thereto, and (B) the percentage equal to 94.5% minus 0.2% for each year by which the age of the retirant’s joint annuitant is less than the retirant’s age, computed to the nearest whole year, or plus 0.2% for each year by which the age of the retirant’s joint annuitant is more than the retirant’s age, computed to the nearest whole year, with 1/2 of that monthly amount continued to the retirant’s joint annuitant during such joint annuitant’s remaining lifetime, if any, after the death of the retirant. In the event that the designated joint annuitant under this option predeceases the retirant, the amount of the retirement benefit otherwise payable to the retirant under this option shall be adjusted automatically to the retirement benefit which the retirant would have received if no option had been elected under this section.

(B) Joint and survivor. A reduced retirement benefit is payable to the retirant during the retirant’s lifetime in a monthly amount equal to the product of (A) the monthly payment of the retirement annuity otherwise payable under Kan.

Ann. § 74-4958, and amendments thereto, and (B) the percentage equal to 88% minus 0.4% for each year by which the age of the retirant’s joint annuitant is less than the retirant’s age, computed to the nearest whole year, or plus 0.4% for each year by which the age of the retirant’s joint annuitant is more than the retirant’s age, computed to the nearest whole year, with that monthly amount continued to the joint annuitant during the joint annuitant’s remaining lifetime, if any, after the death of retirant. In the event that the designated joint annuitant under this option predeceases the retirant, the amount of the retirement benefit otherwise payable to the retirant under this option shall be adjusted automatically to the retirement benefit which the retirant would have received if no option had been elected under this section.

(C) Joint and 3/4 to joint annuitant survivor. A reduced retirement benefit is payable to the retirant during the retirant’s lifetime in a monthly amount equal to the product of (A) the monthly payment of the retirement annuity otherwise payable under Kan. Stat. Ann. § 74-4958, and amendments thereto, and (B) the percentage equal to 91% minus 0.3% for each year by which the age of the retirant’s joint annuitant is less than the retirant’s age, computed to the nearest whole year, or plus 0.3% for each year by which the age of the retirant’s joint annuitant is more than the retirant’s age, computed to the nearest whole year, with 3/4 of that monthly amount continued to the retirant’s joint annuitant during such joint annuitant’s remaining lifetime, if any, after the death of the retirant. In the event that the designated joint annuitant under this option predeceases the retirant, the amount of the retirement benefit otherwise payable to the retirant under this option shall be adjusted automatically to the retirement benefit which the retirant would have received if no option had been elected under this section.

(D) Life with 5 years certain. A reduced retirement benefit is payable to the retirant during the retirant’s lifetime in a monthly amount equal to 99% of the monthly payment of the retirement benefit otherwise payable under Kan.

The lump sum amount designated by the member must be in 10% increments and shall not exceed 1/2 of the actuarial present value of the benefit provided in Kan. Stat. Ann. § 74-4958, and amendments thereto. If the member’s spouse elects a lump sum payment as provided in this section pursuant to the provisions of subsection (6), the lump sum payment will be based on the present value of the retirement option selected by the spouse. The lump sum amount designated by the spouse must be in 10% increments and shall not exceed 1/2 of the actuarial present value of the option selected in this section.
