Effective - 28 Aug 2018, 2 histories   104.1024. Retirement, application — annuity payments, how paid, amount — election to receive annuity or lump sum payment for certain employees, determination of amount. — 1. Any member who terminates employment may retire on or after attaining normal retirement eligibility by making application in written form and manner approved by the appropriate board. The written application shall set forth the annuity starting date which shall not be earlier than the first day of the second month following the month of the execution and filing of the member's application for retirement nor later than the first day of the fourth month following the month of the execution and filing of the member's application for retirement. The payment of the annuity shall be made the last working day of each month, providing all documentation required under section 104.1027 for the calculation and payment of the benefits is received by the board.  2. A member's annuity shall be paid in the form of a life annuity, except as provided in section 104.1027, and shall be an amount for life equal to one and seven-tenths percent of the final average pay of the member multiplied by the member's years of credited service.  3. The life annuity defined in subsection 2 of this section shall not be less than a monthly amount equal to fifteen dollars multiplied by the member's full years of credited service.  4. If as of the annuity starting date of a member who has attained normal retirement eligibility the sum of the member's years of age and years of credited service equals eighty or more years and if the member's age is at least forty-eight years but less than sixty-two years, or, in the case of a member of the highway patrol who shall be subject to the mandatory retirement provision of section 104.080, the mandatory retirement age and completion of five years of credited service, then in addition to the life annuity described in subsection 2 of this section, the member shall receive a temporary annuity equal to eight-tenths of one percent of the member's final average pay multiplied by the member's years of credited service. The temporary annuity and any cost-of-living adjustments attributable to the temporary annuity pursuant to section 104.1045 shall terminate at the end of the calendar month in which the earlier of the following events occurs: the member's death or the member's attainment of the earliest age of eligibility for reduced Social Security retirement benefits, but no later than age sixty-two.  5. The annuity described in subsection 2 of this section for any person who has credited service not covered by the federal Social Security Act, as provided in sections 105.300 to 105.430, shall be calculated as follows: the life annuity shall be an amount equal to two and five-tenths percent of the final average pay of the member multiplied by the number of years of service not covered by the federal Social Security Act in addition to one and seven-tenths percent of the final average pay of the member multiplied by the member's years of credited service covered by the federal Social Security Act.  6. Effective July 1, 2002, any member, except an elected official or a member of the general assembly, who has not been paid retirement benefits and continues employment for at least two years beyond the date of normal retirement eligibility, may elect to receive an annuity and lump sum payment or payments, determined as follows:  (1) A retroactive starting date shall be established which shall be a date selected by the member; provided, however, that the retroactive starting date selected by the member shall not be a date which is earlier than the date when a normal annuity would have first been payable. In addition, the retroactive starting date shall not be more than five years prior to the annuity starting date. The member's selection of a retroactive starting date shall be done in twelve-month increments, except this restriction shall not apply when the member selects the total available time between the retroactive starting date and the annuity starting date;  (2) The prospective annuity payable as of the annuity starting date shall be determined pursuant to the provisions of this section, with the exception that it shall be the amount which would have been payable at the annuity starting date had the member actually retired on the retroactive starting date under the retirement plan selected by the member. Other than for the lump sum payment or payments specified in subdivision (3) of this subsection, no other amount shall be due for the period between the retroactive starting date and the annuity starting date;  (3) The lump sum payable shall be ninety percent of the annuity amounts which would have been paid to the member from the retroactive starting date to the annuity starting date had the member actually retired on the retroactive starting date and received a life annuity. The member shall elect to receive the lump sum amount either in its entirety at the same time as the initial annuity payment is made or in three equal annual installments with the first payment made at the same time as the initial annuity payment;  (4) Any annuity payable pursuant to this section that is subject to a division of benefit order pursuant to section 104.1051 shall be calculated as follows:  (a) Any service of a member between the retroactive starting date and the annuity starting date shall not be considered credited service except for purposes of calculating the division of benefit; and  (b) The lump sum payment described in subdivision (3) of this section shall not be subject to any division of benefit order; and  (5) For purposes of determining annual benefit increases payable as part of the lump sum and annuity provided pursuant to this section, the retroactive starting date shall be considered the member's date of retirement. ­­-------- (L. 1999 S.B. 308 & 314, A.L. 2000 H.B. 1808, A.L. 2001 S.B. 371, A.L. 2002 H.B. 1455, A.L. 2003 S.B. 248, et al., A.L. 2007 S.B. 406, A.L. 2018 S.B. 975 & 1024 Revision)
