(40 ILCS 5/15-146) (from Ch. 108 1/2, par. 15-146)
    Sec. 15-146. Survivors insurance benefits - Minimum amounts.
    (a) The minimum total survivors annuity payable on account of the death of a participant shall be 50% of the retirement annuity which would have been provided under Rule 1, Rule 2, or Rule 3 of Section 15-136 upon the participant's attainment of the minimum age at which the penalty for early retirement would not be applicable or the date of the participant's death, whichever is later, on the basis of credits earned prior to the time of death.
    (b) The minimum total survivors annuity payable on account of the death of an annuitant shall be 50% of the retirement annuity which is payable under Section 15-136 at the time of death or 50% of the disability retirement annuity payable under Section 15-153.2. This minimum survivors annuity shall apply to each participant and annuitant who dies after September 16, 1979, whether or not his or her employee status terminates before or after that date.
    (c) If an annuitant has elected a reversionary annuity, the retirement annuity referred to in this Section is that which would have been payable had such election not been filed.
    (d) Beginning January 1, 2002, any person who is receiving a survivors annuity under this Article which, after inclusion of all one-time and automatic annual increases to which the person is entitled, is less than the sum of $17.50 for each year (up to a maximum of 30 years) of the deceased member's service credit, shall be entitled to a monthly supplemental payment equal to the difference.
    If 2 or more persons are receiving survivors annuities based on the same deceased member, the calculation of the supplemental payment under this subsection shall be based on the total of those annuities and divided pro rata. The supplemental payment is not subject to any limitation on the maximum amount of the annuity and shall not be included in the calculation of any automatic annual increase under Section 15-145.
