(40 ILCS 5/2-120) (from Ch. 108 1/2, par. 2-120)
    Sec. 2-120. Reversionary annuity.
    (a) Prior to retirement, a participant may elect to take a reduced retirement annuity and provide, with the actuarial value of the amount of the reduction in annuity, a reversionary annuity for a spouse, parent, child, brother or sister. The option shall be exercised by the filing of a written designation with the board prior to retirement, and may be revoked by the participant at any time before retirement. The death of the participant or the designated reversionary annuitant prior to the participant's retirement shall automatically void this option. If the reversionary annuitant dies after the participant's retirement, the reduced annuity being paid to the retired participant shall remain unchanged and no reversionary annuity shall be payable.
    (b) A reversionary annuity shall not be payable if the participant dies before the expiration of 2 years from the date the written designation was filed with the board even though he or she had retired and was receiving a reduced retirement annuity under this option.
    (c) A reversionary annuity shall begin on the first day of the month following the death of the annuitant and continue until the death of the reversionary annuitant.
    (d) For a member electing to take a reduced annuity under this Section, the automatic increases provided in Section 2-119.1 shall be applied to the amount of the reduced retirement annuity.
