    Sec. 17-116.6. Early retirement incentives.
    (a) A teacher who is covered by a collective bargaining agreement shall not be eligible for the early retirement incentives provided under this Section unless the collective bargaining agent and the Board of Education have entered into an agreement under which the agent agrees that any payment for accumulated unused sick days to which the employee is entitled upon withdrawal from service may be paid by the Board of Education in installments over a period of up to 5 years, and a copy of this agreement has been filed with the Board of the Fund.
     To be eligible for the benefits provided in this Section, a person must:
        (1) be a member of this Fund who is a reserve teacher
    
as defined in Section 34-1.1 of the School Code;
        (2) have not previously received a bachelor's or more
    
advanced degree from an accredited college or university;
        (3) have not previously received a retirement pension
    
under this Article;
        (4) file with the Board and the Board of Education,
    
by the later of 60 days after the effective date of this amendatory Act of 1993 or 60 days after becoming a reserve teacher, but in no event later than December 31, 1995, a written application requesting the benefits provided in this Section;
        (5) be eligible to receive a retirement pension under
    
this Article (for which purpose any age enhancement or creditable service received under this Section may be used) and elect to receive the retirement pension beginning no earlier than September 1, 1993, and no later than 120 days after becoming a reserve teacher;
        (6) have attained age 50 (without the use of any age
    
enhancement or creditable service received under this Section) by the effective date of the retirement pension;
        (7) have at least 5 years of creditable service under
    
this Fund or any of the participating systems under the Retirement Systems Reciprocal Act (without the use of any creditable service received under this Section) by the effective date of the retirement pension.
    (b) An eligible person may establish up to 5 years of creditable service under this Section. In addition, for each period of creditable service established under this Section, a person's age at retirement shall be deemed to be increased by an equal period.
    The creditable service established under this Section may be used for all purposes under this Article and the Retirement Systems Reciprocal Act, except for the purposes of Section 17-116.1, and the determination of average salary or compensation under this or any other Article of this Code.
    The age enhancement established under this Section may be used for all purposes under this Article (including calculation of a proportionate pension payable by this Fund under the Retirement Systems Reciprocal Act), except for purposes of the reversionary pension under Section 17-120, and distributions required by federal law on account of age. However, age enhancement established under this Section shall not be used in determining benefits payable under other Articles of this Code under the Retirement Systems Reciprocal Act.
    (c) For all creditable service established under this Section, the employer must pay to the Fund an employer contribution consisting of 12% of the member's highest annual full-time rate of compensation for each year of creditable service granted under this Section.
    The employer contribution shall be paid to the Fund in one of the following ways: (i) in a single sum at the time of the member's retirement, (ii) in equal quarterly installments over a period of 5 years from the date of retirement, or (iii) subject to the approval of the Board of the Fund, in unequal installments over a period of no more than 5 years from the date of retirement, as provided in a payment plan designed by the Fund to accommodate the needs of the employer. The employer's failure to make the required contributions in a timely manner shall not affect the payment of the retirement pension.
    For all creditable service established under this Section, the employee must pay to the Fund an employee contribution consisting of 4% of the member's highest annual salary rate used in the determination of the retirement pension for each year of creditable service granted under this Section. The employee contribution shall be deducted from the retirement annuity in 24 monthly installments.
    (d) An annuitant who has received any age enhancement or creditable service under this Section and whose pension is suspended or cancelled under Section 17-149 or 17-150 shall thereby forfeit the age enhancement and creditable service. The forfeiture of creditable service under this subsection shall not entitle the employer to a refund of the employer contribution paid under this Section, nor to forgiveness of any part of that contribution that remains unpaid. The forfeiture of creditable service under this subsection shall not entitle the employee to a refund of the employee contribution paid under this Section.
    (e) A member who receives any early retirement incentive under Section 17-116.3, 17-116.4, or 17-116.5 may not receive any early retirement incentive under this Section.
