Additional optional contributions for the alternative annuity shall be as follows:
In lieu of the retirement annuity otherwise payable under this Article, any commissioner who has elected to participate in the Fund and make additional optional contributions in accordance with this Section, has attained age 55, and has at least 6 years of service credit, may elect to have the retirement annuity computed as follows: 3% of the participant's average final salary as a commissioner for each of the first 8 years of service credit, plus 4% of such salary for each of the next 4 years of service credit, plus 5% of such salary for each year of service credit in excess of 12 years, subject to a maximum of 80% of such salary. To the extent such commissioner has made additional optional contributions with respect to only a portion of years of service credit, the retirement annuity will first be determined in accordance with this Section to the extent such additional optional contributions were made, and then in accordance with the remaining Sections of this Article to the extent of years of service credit with respect to which additional optional contributions were not made. The change in minimum retirement age (from 60 to 55) made by Public Act 87-1265 applies to persons who begin receiving a retirement annuity under this Section on or after January 25, 1993 (the effective date of Public Act 87-1265), without regard to whether they are in service on or after that date.
The annuity shall be payable beginning on the date of the commissioner's death if the spouse is then age 50 or over, or beginning at age 50 if the age of the spouse is less than 50 years. If a minor unmarried child or children of the commissioner, under age 18 (age 23 in the case of a full-time student), also survive, and the child or children are under the care of the eligible spouse, the annuity shall begin as of the date of death of the commissioner without regard to the spouse's age. Beginning on the first day of the month following the month in which this amendatory Act of the 96th General Assembly takes effect, benefits shall begin on the first of the month following the commissioner's date of death if the spouse is then age 50 or over or, if a minor unmarried child or children of the commissioner, under age 18 (age 23 in the case of a full time student), also survive, and the child or children are under the care of the eligible spouse. The benefit is payable for the full month if the annuitant was alive on the first day of the month.
The annuity to a spouse shall be the greater of (i) 66 2/3% of the amount of retirement annuity earned by the commissioner on the date of death, subject to a minimum payment of 10% of salary, provided that if an eligible spouse, regardless of age, has in his or her care at the date of death of the commissioner any unmarried child or children of the commissioner under age 18, the minimum annuity shall be 30% of the commissioner's salary, plus 10% of salary on account of each minor child of the commissioner, subject to a combined total payment on account of a spouse and minor children not to exceed 50% of the deceased commissioner's salary or (ii) for the spouse of a commissioner whose death occurs on or after August 18, 2005 (the effective date of Public Act 94-621), the surviving spouse annuity shall be computed in the same manner as described in Section 13-306(a). The number of total service years used to calculate the commissioner's annuity shall be the number of service years used to calculate the annuity for that commissioner's surviving spouse. In the event there shall be no spouse of the commissioner surviving, or should a spouse die while eligible minor children still survive the commissioner, each such child shall be entitled to an annuity equal to 20% of salary of the commissioner subject to a combined total payment on account of all such children not to exceed 50% of salary of the commissioner. The salary to be used in the calculation of these benefits shall be the same as that prescribed for determining a retirement annuity as provided in subsection (b) of this Section.
Upon the death of a commissioner occurring after termination of a service or while in receipt of a retirement annuity, the combined total payment to a spouse and minor children, or to minor children alone if no eligible spouse survives, shall be limited to 85% of the amount of retirement annuity earned by the commissioner.
Marriage of a child or attainment of age 18 (age 23 in the case of a full-time student), whichever first occurs, shall render the child ineligible for further consideration in the payment of annuity to a spouse or in the increase in the amount thereof. Upon attainment of ineligibility of the youngest minor child of the commissioner, the annuity shall immediately revert to the amount payable upon death of a commissioner leaving no minor children surviving. If the spouse is under age 50 at such time, the annuity as revised shall be deferred until such age is attained.
Optional contributions shall be accounted for in a separate Commission's Optional Contribution Reserve. Optional contributions under this Section shall be included in the amount of employee contributions used to compute the tax levy under Section 13-503.
