Mo. Rev. Stat. § 86.1151
in effect86.1151. Tier II members, retire when — benefits, how computed. — 1. Any Tier II member may retire when such member has completed twenty-seven or more years of creditable service. Upon such retirement such member shall receive a base pension equal to two and one-half percent of such member's final compensation, as defined in section 86.900 , multiplied by the number of years of such member's total creditable service. Such pension shall not exceed eighty percent of the member's final compensation.
2. (1) A Tier II member who is married at the time of retirement may by a written election, with the written consent of such member's spouse, elect an optional benefit calculated as follows: such optional benefit shall be a monthly pension in the initial amount which shall be actuarially equivalent to the actuarial value of the pension described in subsection 1 of this section for such member at the date of retirement (including the value of survivorship rights of a surviving spouse, where applicable, under section 86.1240 ), upon the basis that the initial annuity for the member's spouse, if such spouse survives the member, shall be:
(a) The same as the amount being paid the member at the member's death, and, together with cost-of-living adjustments thereafter declared on the spouse's base pension under section 86.1220 , shall be paid to such surviving spouse for the lifetime of such spouse; or
(b) Seventy-five percent of the amount being paid the member at the member's death, and, together with cost-of-living adjustments thereafter declared on the spouse's base pension under section 86.1220 , shall be paid to such surviving spouse for the lifetime of such spouse.
(2) If a member who elects the optional benefit permitted by this subsection also makes an election permitted under section 86.1210 , such optional benefit shall be reduced as provided in subdivision (3) of subsection 2 of section 86.1210 .
(3) If a member makes the election permitted by this subsection, the amount calculated for such optional benefit under either subdivision (1) or (2) of this subsection shall become the base pension for such member and for such member's spouse for all purposes of sections 86.900 to 86.1280 .
(4) An election for an optional benefit under this subsection shall be void if the member dies within thirty days after filing such election with the retirement system or if the member dies before the due date of the first payment of such member's pension.
3. Subject to the provisions of subsection 4 of this section, whenever the service of a Tier II member is terminated for any reason prior to death or retirement and the member has fifteen or more years of creditable service, the member may elect not to withdraw such member's accumulated contributions and shall become entitled to a base pension commencing on the first day of the month following the attainment of the age of sixty, if then living, equal to two and one-half percent of such member's final compensation multiplied by the number of years of such member's creditable service.
4. Notwithstanding any other provisions of sections 86.900 to 86.1280 , any member who is convicted of a felony prior to separation from active service shall not be entitled to any benefit from this retirement system except the return of such member's accumulated contributions.
