(40 ILCS 5/17-120) (from Ch. 108 1/2, par. 17-120)
    Sec. 17-120. Reversionary pension. Any contributor, at any time prior to retirement on a service retirement pension, may exercise an option of taking a lesser amount of service retirement pension and providing with the remainder of his equity, determined on an actuarial equivalent basis, a reversionary pension benefit for any person named in a written designation filed by the contributor with the Board, provided that the pension resulting from such election is not less than $40 per month, or more than the reduced pension payable after the exercise of the option. If the reduced pension to the retired teacher is less than that provided for a beneficiary, whether or not the aforesaid minimum amount is payable, the election shall be void.
    The pension to a beneficiary shall begin on the first day of the month next following the month in which the retired teacher dies.
    If the beneficiary survives the date of retirement of the teacher, but does not survive the retired teacher, no reversionary pensions shall be payable, and the teacher's service pension shall be restored to the full service pension amount beginning on the first day of the month next following the month in which the beneficiary dies or on the effective date of this amendatory Act of 1997, whichever occurs later.
    If the beneficiary dies after the election but before the retirement of the teacher, the election shall be void. No change shall be permitted in the written designation filed with the Board.
    In the case of a reversionary annuity elected on or after January 1, 1984, no reversionary annuity shall be paid if the teacher dies before the expiration of 730 days from the date that a written designation was filed with the Board, even though the teacher was receiving a reduced annuity.
    Sections 1-103.1 and 17-157 do not apply to the changes made to this Section by this amendatory Act of 1997.
