Annuities and lump sum payments, when, determination of amount. — Effective July 1, 2002, any member retiring pursuant to the provisions of sections 104.010 to 104.801, 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 normal retirement age, 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, which shall be the first day of the month with respect to which an amount is paid as an annuity pursuant to this section. 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 otherwise applicable under the law, with the exception that it shall be the amount which would have been payable 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 section, 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 normal 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 104.312 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 creditable 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. 2001 S.B. 371, A.L. 2002 H.B. 1455)  Effective 7-11-02
