    (b) Subject to authorization by the Employer as provided in subsection (c), a member retiring on or after June 30, 1995 and on or before June 30, 2010 and within 6 months of the last day of teaching for which retirement contributions were required may elect at the time of application to make a one-time employee contribution to the Fund and thereby avoid the early retirement reduction in allowance specified in paragraph (4) of Section 17-116. The exercise of the election shall obligate the last Employer to also make a one-time nonrefundable contribution to the Fund.
    (c) The benefits provided in subsection (b) are available only to members who retire, during a specified period, from employment with an Employer that has adopted and filed with the Board a resolution expressly providing for the creation of an early retirement without discount program under this Section for that period.
    The Employer has the full discretion and authority to determine whether an early retirement without discount program is in its best interest and to provide such a program to its eligible employees in accordance with this Section. The Employer may decide to authorize such a program for one or more of the following periods: for the period beginning July 1, 1997 and ending June 30, 1998, in which case the resolution must be adopted by January 1, 1998; for the period beginning July 1, 1998 and ending June 30, 1999, in which case the resolution must be adopted by March 31, 1998; for the period beginning July 1, 1999 and ending June 30, 2000, in which case the resolution must be adopted by March 31, 1999; for the period beginning July 1, 2000 and ending June 30, 2001, in which case the resolution must be adopted by March 31, 2000; for the period beginning July 1, 2001 and ending June 30, 2002, in which case the resolution must be adopted by March 31, 2001; for the period beginning July 1, 2002 and ending June 30, 2003, in which case the resolution must be adopted by March 31, 2002; for the period beginning July 1, 2003 and ending June 30, 2004, in which case the resolution must be adopted by March 31, 2003; for the period beginning July 1, 2004 and ending June 30, 2005, in which case the resolution must be adopted by March 31, 2004; for the period beginning July 1, 2005 and ending June 30, 2006, in which case the resolution must be adopted by August 31, 2005; for the period beginning July 1, 2006 and ending June 30, 2007, in which case the resolution must be adopted by June 30, 2006; for the period beginning July 1, 2007 and ending June 30, 2008, in which case the resolution must be adopted by June 30, 2007; for the period beginning July 1, 2008 and ending June 30, 2009, in which case the resolution must be adopted by June 30, 2008; and for the period beginning July 1, 2009 and ending June 30, 2010, in which case the resolution must be adopted by June 30, 2009. The resolution must be filed with the Board within 10 days after it is adopted. A single resolution may authorize an early retirement without discount program as provided in this Section for more than one period.
    Notwithstanding Section 17-157, the Employer shall also have full discretion and authority to determine whether to allow its employees who withdrew from service on or after June 30, 1995 and before June 27, 1997 to participate in an early retirement without discount program under subsection (b). An early retirement without discount program for those who withdrew from service on or after June 30, 1995 and before June 27, 1997 may be authorized only by a resolution of the Employer that is adopted by January 1, 1998 and filed with the Board within 10 days after its adoption. If such a resolution is duly adopted and filed, a person who (i) withdrew from service with the Employer on or after June 30, 1995 and before June 27, 1997, (ii) qualifies for early retirement without discount under subsection (b), (iii) applies to the Fund within 90 days after the authorizing resolution is adopted, and (iv) pays the required employee contribution shall have his or her retirement pension recalculated in accordance with subsection (b). The resulting increase shall be effective retroactively to the starting date of the retirement pension.
    (d) The one-time employee contribution shall be equal to 7% of the retiring member's highest full-time annual salary rate used in the determination of the average salary rate for retirement pension, or if not full-time then the full-time equivalent, multiplied by (1) the number of years the teacher is under age 60, or (2) the number of years the employee's creditable service is less than 34 years, whichever is less.
    The Employer contribution shall be 20% of such salary multiplied by such number of years.
    (e) Upon receipt of the application and election, the Board shall determine the one time employee and Employer contributions. The provisions of this Section shall not be applicable until the employee contribution, if any, has been received by the Fund; however, the date that contribution is received shall not be considered in determining the effective date of retirement.
    (f) The number of employees who may retire under this Section in any year may be limited at the option of the Employer to a specified number of those eligible, not lower than 200, but the Employer and the collective bargaining agent for teachers may agree upon a greater limitation to the specified number of employees who may retire under this Section in any year. The right to participate in the early retirement without discount authorized under this Section shall be allocated among those applying on the basis of seniority in the service of the Employer or on such other basis for allocation as the Employer and the collective bargaining agent for teachers agree, in which case, such other basis may be employed among other eligible employees as well.

A teacher who becomes wholly and presumably permanently incapacitated for duty while under age 65 as the proximate result of injuries sustained or a hazardous condition encountered in the performance and within the scope of his duties, if such injury or hazard was not the result of his own negligence, shall be entitled to a duty disability benefit, provided:

    (40 ILCS 5/17-118) (from Ch. 108 1/2, par. 17-118)
    Sec. 17-118. Disability pension administration. A disability pensioner may be required to submit to an examination periodically by a physician or physicians appointed by the Board. The purpose of the examination is to establish whether the disability still exists and to determine whether the person is still incapacitated for teaching service or service as an employee of the Board. The Board may require disability pensioners to submit evidence of the continued existence of the disability. The Board may also employ investigative services to determine whether such pensioners are employed elsewhere as teachers or to establish whether they are still disabled.
    The Board shall cancel a disability pension upon evidence that a pensioner is no longer incapacitated for teaching or service as an employee of the Board. However, if a pensioner has attained age 55 and has 20 or more years of service, the pension shall not be cancelled unless he is re-employed as a teacher or as a pensioner-substitute. If a disability pensioner is re-employed as a teacher or pensioner-substitute, the pension shall be cancelled on the first day of re-employment. The pensioner shall reimburse the Fund for pension payments received after the date of re-employment (if any), plus 5% interest compounded annually beginning one year after the Fund's notification of the cancellation and indebtedness. Upon cancellation of a disability pension, unless such person re-enters service and becomes a contributor, a refund shall be payable of the excess, if any, of the refundable contributions paid by him over the amount paid in disability pension.

    Sec. 17-119. Automatic annual increase in pension. Each teacher retiring on or after September 1, 1959, is entitled to the annual increase in pension, defined herein, while he is receiving a pension from the Fund.
    1. The term "base pension" means a service retirement or disability retirement pension in the amount fixed and payable at the date of retirement of a teacher.
    2. The annual increase in pension shall be at the rate of 1 1/2% of base pension. This increase shall first occur in January of the year next following the first anniversary of retirement. At such time the Fund shall pay the pro rata part of the increase for the period from the first anniversary date to the date of the first increase in pension. Beginning January 1, 1972, the rate of annual increase in pension shall be 2% of the base pension. Beginning January 1, 1979, the rate of annual increase in pension shall be 3% of the base pension. Beginning January 1, 1990, all automatic annual increases payable under this Section shall be calculated as a percentage of the total pension payable at the time of the increase, including all increases previously granted under this Article, notwithstanding Section 17-157.
    3. An increase in pension shall be granted only if the retired teacher is age 60 or over. If the teacher attains age 60 after retirement, the increase in pension shall begin in January of the year following the 61st birthday. At such time the Fund also shall pay the pro rata part of the increase from the 61st birthday to the date of first increase in pension.
    In addition to other increases which may be provided by this Section, on January 1, 1981 any teacher who was receiving a retirement pension on or before January 1, 1971 shall have his retirement pension then being paid increased $1 per month for each year of creditable service. On January 1, 1982, any teacher whose retirement pension began on or before January 1, 1977, shall have his retirement pension then being paid increased $1 per month for each year of creditable service.
    On January 1, 1987, any teacher whose retirement pension began on or before January 1, 1977, shall have the monthly retirement pension increased by an amount equal to 8¢ per year of creditable service times the number of years that have elapsed since the retirement pension began.

Any member who retires on or after July 1, 1998 and before the effective date of this amendatory Act of the 92nd General Assembly with at least 30 years of creditable service shall be paid a lump sum equal to the amount he or she would have received under the augmented rate minus the amount he or she actually received. A member may not elect to qualify for the augmented rate for only a portion of his or her creditable service earned before July 1, 1998.
    (b) The contribution shall be an amount equal to 1.0% of the member's highest salary rate in the 4 consecutive school years immediately prior to but not including the school year in which the application occurs, multiplied by the number of years of creditable service earned by the member before July 1, 1998 or 20, whichever is less. This contribution shall be reduced by 1.0% of that salary rate for every 3 full years of creditable service earned by the member after June 30, 1998. The contribution shall be further reduced at the rate of 25% of the contribution (as reduced for service after June 30, 1998) for each year of the member's total creditable service in excess of 34 years. The contribution shall not in any event exceed 20% of that salary rate.
    The member shall pay to the Fund the amount of the contribution as calculated at the time of application under this Section. The amount of the contribution determined under this subsection shall be recalculated at the time of retirement, and if the Fund determines that the amount paid by the member exceeds the recalculated amount, the Fund shall refund the difference to the member with regular interest from the date of payment to the date of refund.
    The contribution required by this subsection shall be paid in one of the following ways or in a combination of the following ways that does not extend over more than 5 years:
        (i) in a lump sum on or before the date of retirement;
        (ii) in substantially equal installments over a

    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.

    Sec. 17-121. Survivor's pensions - Eligibility.
    (a) A surviving spouse of a teacher shall be entitled to a survivor's pension only if the surviving spouse was married to the teacher for at least one year immediately prior to the teacher's death.
    The changes made to this subsection (a) by this amendatory Act of the 92nd General Assembly apply (i) only to the surviving spouse of a person who dies on or after the effective date of this amendatory Act, and only if the amount of any refund of contributions for survivor's pension is repaid with interest in accordance with subsection (f), and (ii) notwithstanding Section 17-157 and without regard to whether the deceased person was in service on or after the effective date of this amendatory Act.
    (b) If the surviving spouse is under age 50 and there are no eligible minor children born to or legally adopted by the contributor and his or her surviving spouse, payment of the survivor's pension shall begin when the surviving spouse attains age 50.
    (c) Beginning January 1, 2003, the remarriage of a surviving spouse at any age does not terminate his or her survivor's pension.
    A surviving spouse whose survivor's pension (or expectation of a survivor's pension upon attainment of age 50) was terminated before January 1, 2003 due to remarriage and who applies for reinstatement of that pension and repays the amount of any refund of contributions for survivor's pension with interest in accordance with subsection (f) shall be entitled to have the survivor's pension (or expectation of a survivor's pension upon attainment of age 50) reinstated. The reinstated pension shall begin to accrue on the first day of the month following the month in which the application and repayment, if any, are received by the Fund, but in no event sooner than January 1, 2003 and, if subsection (b) applies, no sooner than upon attainment of age 50. The reinstated pension shall include any one-time or annual increases in the survivor's pension received prior to the date of termination, but not any increases that would otherwise have accrued from the date of termination to the date of reinstatement.
    This subsection (c) applies notwithstanding Section 17-157 and without regard to whether the deceased teacher was in service on or after the effective date of this amendatory Act of the 92nd General Assembly.
    (d) Except as provided in subsection (c), remarriage of the surviving spouse prior to September 1, 1983 while in receipt of a survivor's pension shall permanently terminate payment thereof, regardless of any subsequent change in marital status; however, beginning September 1, 1983, remarriage of a surviving spouse after attainment of age 55 shall not terminate the survivor's pension.
    A surviving spouse whose pension was terminated on or after September 1, 1983 due to remarriage after attainment of age 55, and who applies for reinstatement of that pension before January 1, 1990, shall be entitled to have the pension reinstated effective January 1, 1990.
    (e) A surviving spouse of a member or annuitant under this Fund who is also a dependent beneficiary under the provisions of Section 16-140 is eligible for a reciprocal survivor's pension, provided that any refund of survivor's pension contributions is repaid to the Fund and application is made within 30 days after the effective date of this amendatory Act of the 92nd General Assembly.
    (f) If a refund of contributions for survivor's pension has been paid, a person choosing to establish or reestablish the right to receive a survivor's pension pursuant to the changes made to this Section by this amendatory Act of the 92nd General Assembly must first repay to the Fund the amount of the refund of contributions for survivor's pension, together with interest thereon at the rate of 5% per year, compounded annually, from the date of the refund to the date of repayment.

    Sec. 17-122. Survivor's and children's pensions - Amount. Upon the death of a teacher who has completed at least 1 1/2 years of contributing service with either this Fund or the State Universities Retirement System or the Teachers' Retirement System of the State of Illinois, provided his death occurred while (a) in active service covered by the Fund or during his first 18 months of continuous employment without a break in service under any other participating system as defined in the Illinois Retirement Systems Reciprocal Act except the State Universities Retirement System and the Teachers' Retirement System of the State of Illinois, (b) on a creditable leave of absence, (c) on a noncreditable leave of absence of no more than one year, or (d) a pension was deferred or pending provided the teacher had at least 10 years of validated service credit, or upon the death of a pensioner otherwise qualified for such benefit, the surviving spouse and unmarried minor children of the deceased teacher under age 18 shall be entitled to pensions, under the conditions stated hereinafter. Such survivor's and children's pensions shall be based on the average of the 4 highest consecutive years of salary in the last 10 years of service or on the average salary for total service, if total service has been less than 4 years, according to the following percentages:
    30% of average salary or 50% of the retirement pension earned by the teacher, whichever is larger, subject to the prescribed maximum monthly payment, for a surviving spouse alone on attainment of age 50;
    60% of average salary for a surviving spouse and eligible minor children of the deceased teacher.
    If no eligible spouse survives, or the surviving spouse remarries, or the parent of the children of the deceased member is otherwise ineligible for a survivor's pension, a children's pension for eligible minor children under age 18 shall be paid to their parent or legal guardian for their benefit according to the following percentages:
    30% of average salary for one child;
    60% of average salary for 2 or more children.
    On January 1, 1981, any survivor or child who was receiving a survivor's or children's pension on or before January 1, 1971, shall have his survivor's or children's pension then being paid increased by 1% for each full year which has elapsed from the date the pension began. On January 1, 1982, any survivor or child whose pension began after January 1, 1971, but before January 1, 1981, shall have his survivor's or children's pension then being paid increased 1% for each full year which has elapsed from the date the pension began. On January 1, 1987, any survivor or child whose pension began on or before January 1, 1977, shall have the monthly survivor's or children's pension increased by $1 for each full year which has elapsed since the pension began.
    Beginning January 1, 1990, every survivor's and children's pension shall be increased (1) on each January 1 occurring on or after the commencement of the pension if the deceased teacher died while receiving a retirement pension, or (2) in other cases, on each January 1 occurring on or after the first anniversary of the commencement of the pension, by an amount equal to 3% of the current amount of the pension, including all increases previously granted under this Article, notwithstanding Section 17-157. Such increases shall apply without regard to whether the deceased teacher was in service on or after the effective date of this amendatory Act of 1991, but shall not accrue for any period prior to January 1, 1990.
    Subject to the minimum established below, the maximum amount of pension for a surviving spouse alone or one minor child shall be $400 per month, and the maximum combined pensions for a surviving spouse and children of the deceased teacher shall be $600 per month, with individual pensions adjusted for all beneficiaries pro rata to conform with this limitation. If proration is unnecessary the minimum survivor's and children's pensions shall be $40 per month. The minimum total survivor's and children's pension payable upon the death of a contributor or annuitant which occurs after December 31, 1986, shall be 50% of the earned retirement pension of such contributor or annuitant, calculated without early retirement discount in the case of death in service.
    On death after retirement, the total survivor's and children's pensions shall not exceed the monthly retirement or disability pension paid to the deceased retirant. Survivor's and children's benefits described in this Section shall apply to all service and disability pensioners eligible for a pension as of July 1, 1981.

If a teacher dies (a) in service, (b) after resignation or (c) after retirement but before receiving any pension payment, his or her estate shall be paid a refund of the amounts he or she contributed to the Fund less (1) any former refund that has not been repaid, (2) the amount contributed for a survivor's pension in the event such pension is payable under Sections 17-121 and 17-122 and (3) pension payments received; but if a written direction, signed by the contributor before an officer authorized to take acknowledgments and stating that the refund shall be paid to named beneficiaries, was filed with the Board prior to his or her death, the refund shall be paid to such named beneficiaries. If any of several named beneficiaries does not survive the contributor and no directive was furnished by the member to cover this contingency, the deceased beneficiary's share of the refund shall be paid to the estate of the contributor.
    In addition to the payment provided in the foregoing paragraph, if such teacher has received service credit within 13 calendar months of the date of death or was on a sick leave authorized by the Employer at the time of death, and if no other pensions or benefits were payable under the provisions of this Article or any other participating system, as defined in the Illinois Retirement Systems Reciprocal Act, except a refund of contributions or a survivor's pension, there shall be paid a single payment death benefit.

The single payment death benefit shall be paid in the manner prescribed for a refund of contributions to the Fund.

    (a) An Employer or the Board shall make pension deductions in each pay period on the basis of the salary earned in that period, exclusive of salaries for overtime, special services, or any employment on an optional basis, such as in summer school.
    (b) If a salary paid in a pay period includes adjustments on account of errors or omissions in prior pay periods, then salary amounts and related pension deductions shall be separately identified as to the adjusted pay period and deductions by the Employer or the Board shall be at rates in force during the applicable adjusted pay period.
    (c) If members earn salaries for the school year, as established by an Employer, or if they earn annual salaries over more than a 10-calendar month period, or if they earn annual salaries over more than 170 calendar days, the required contribution amount shall be deducted by the Employer in installments on the basis of salary earned in each pay period. The total amounts for each pay period shall be deducted whenever salary payments represent a partial or whole day's pay.
    (d) If an Employer or the Board pays a salary to a member for vacation periods, then the salary shall be considered part of the member's pensionable salary, shall be subject to the standard deductions for pension contributions, and shall be considered to represent pay for the number of whole days of vacation.
    (e) If deductions from salaries result in amounts of less than one cent, the fractional sums shall be increased to the next higher cent. Any excess of these fractional increases over the prescribed annual contributions shall be credited to the members' accounts.

    (e) The Board has the authority to conduct payroll audits of a charter school to determine the existence of any delinquencies in contributions to the Fund, and such charter school shall be required to provide such books and records and contribution information as the Board or its authorized representative may require. The Board is also authorized to collect delinquent contributions from charter schools and develop procedures for the collection of such delinquencies. Collection procedures may include legal proceedings in the courts of the State of Illinois.

    When the member again retires on pension, the time of service and the money contributed by him during re-employment shall be added to the time and money previously credited. Such person must acquire 3 consecutive years of additional contributing service before he may retire again on a pension at a rate and under conditions other than those in force or attained at the time of his previous retirement.
    (c-5) The service retirement pension shall not be cancelled in the case of a service retirement pensioner who is re-employed as a teacher on a temporary and non-annual basis or on an hourly basis, so long as the person (1) does not work as a teacher for compensation on more than 100 days in a school year and (2) does not accept gross compensation for the re-employment in a school year in excess of (i) $30,000 or (ii) in the case of a person who retires with at least 5 years of service as a principal, an amount that is equal to the daily rate normally paid to retired principals multiplied by 100. These limitations apply only to school years that begin on or after the effective date of this amendatory Act of the 97th General Assembly. Such re-employment does not require contributions, result in service credit, or constitute active membership in the Fund.
    To be eligible for such re-employment without cancellation of pension, the pensioner must notify the Fund and the Board of Education of his or her intention to accept re-employment under this subsection (c-5) before beginning that re-employment (or if the re-employment began before the effective date of this amendatory Act, then within 30 days after that effective date).
    The Board of Education must certify to the Fund the temporary and non-annual or hourly status and the compensation of each pensioner re-employed under this subsection at least quarterly, and when the pensioner is approaching the earnings limitation under this subsection.
    If the pensioner works more than 100 days or accepts excess gross compensation for such re-employment in any school year that begins on or after the effective date of this amendatory Act of the 97th General Assembly, the service retirement pension shall thereupon be cancelled.
    The Board of the Fund shall adopt rules for the implementation and administration of this subsection.
    (d) Notwithstanding Sections 1-103.1 and 17-157, the changes to this Section made by Public Act 90-32 apply without regard to whether termination of service occurred before the effective date of that Act and apply retroactively to August 23, 1989.
    Notwithstanding Sections 1-103.1 and 17-157, the changes to this Section and Section 17-106 made by Public Act 92-599 apply without regard to whether termination of service occurred before the effective date of that Act.
    Notwithstanding Sections 1-103.1 and 17-157, the changes to this Section made by this amendatory Act of the 97th General Assembly apply without regard to whether termination of service occurred before the effective date of this amendatory Act.
