Illinois Compiled Statutes

Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

40 ILCS 5/14-147.5

    (40 ILCS 5/14-147.5)
    Sec. 14-147.5. Accelerated pension benefit payment in lieu of any pension benefit.
    (a) As used in this Section:
    "Eligible person" means a person who:
        (1) has terminated service;
        (2) has accrued sufficient service credit to be
    
eligible to receive a retirement annuity under this Article;
        (3) has not received any retirement annuity under
    
this Article; and
        (4) has not made the election under Section 14-147.6.
    "Pension benefit" means the benefits under this Article, or Article 1 as it relates to those benefits, including any anticipated annual increases, that an eligible person is entitled to upon attainment of the applicable retirement age. "Pension benefit" also includes applicable survivor's or disability benefits.
    (b) As soon as practical after June 4, 2018 (the effective date of Public Act 100-587), the System shall calculate, using actuarial tables and other assumptions adopted by the Board, the present value of pension benefits for each eligible person who requests that information and shall offer each eligible person the opportunity to irrevocably elect to receive an amount determined by the System to be equal to 60% of the present value of his or her pension benefits in lieu of receiving any pension benefit. The offer shall specify the dollar amount that the eligible person will receive if he or she so elects and shall expire when a subsequent offer is made to an eligible person. An eligible person is limited to one calculation and offer per calendar year. The System shall make a good faith effort to contact every eligible person to notify him or her of the election.
    Until June 30, 2026, an eligible person may irrevocably elect to receive an accelerated pension benefit payment in the amount that the System offers under this subsection in lieu of receiving any pension benefit. A person who elects to receive an accelerated pension benefit payment under this Section may not elect to proceed under the Retirement Systems Reciprocal Act with respect to service under this Article.
    (c) A person's creditable service under this Article shall be terminated upon the person's receipt of an accelerated pension benefit payment under this Section, and no other benefit shall be paid under this Article based on the terminated creditable service, including any retirement, survivor, or other benefit; except that to the extent that participation, benefits, or premiums under the State Employees Group Insurance Act of 1971 are based on the amount of service credit, the terminated service credit shall be used for that purpose.
    (d) If a person who has received an accelerated pension benefit payment under this Section returns to active service under this Article, then:
        (1) Any benefits under the System earned as a result
    
of that return to active service shall be based solely on the person's creditable service arising from the return to active service.
        (2) The accelerated pension benefit payment may not
    
be repaid to the System, and the terminated creditable service may not under any circumstances be reinstated.
    (e) As a condition of receiving an accelerated pension benefit payment, the accelerated pension benefit payment must be transferred into a tax qualified retirement plan or account. The accelerated pension benefit payment under this Section may be subject to withholding or payment of applicable taxes, but to the extent permitted by federal law, a person who receives an accelerated pension benefit payment under this Section must direct the System to pay all of that payment as a rollover into another retirement plan or account qualified under the Internal Revenue Code of 1986, as amended.
    (f) Upon receipt of a member's irrevocable election to receive an accelerated pension benefit payment under this Section, the System shall submit a voucher to the Comptroller for payment of the member's accelerated pension benefit payment. The Comptroller shall transfer the amount of the voucher from the State Pension Obligation Acceleration Bond Fund to the System, and the System shall transfer the amount into the member's eligible retirement plan or qualified account.
    (g) The Board shall adopt any rules, including emergency rules, necessary to implement this Section.
    (h) No provision of this Section shall be interpreted in a way that would cause the applicable System to cease to be a qualified plan under the Internal Revenue Code of 1986.

    (40 ILCS 5/14-147.6)
    Sec. 14-147.6. Accelerated pension benefit payment for a reduction in annual retirement annuity and survivor's annuity increases.
    (a) As used in this Section:
    "Accelerated pension benefit payment" means a lump sum payment equal to 70% of the difference of the present value of the automatic annual increases to a Tier 1 member's retirement annuity and survivor's annuity using the formula applicable to the Tier 1 member and the present value of the automatic annual increases to the Tier 1 member's retirement annuity using the formula provided under subsection (b-5) and survivor's annuity using the formula provided under subsection (b-6).
    "Eligible person" means a person who:
        (1) is a Tier 1 member;
        (2) has submitted an application for a retirement
    
annuity under this Article;
        (3) meets the age and service requirements for
    
receiving a retirement annuity under this Article;
        (4) has not received any retirement annuity under
    
this Article; and
        (5) has not made the election under Section 14-147.5.
    (b) As soon as practical after June 4, 2018 (the effective date of Public Act 100-587) and until June 30, 2026, the System shall implement an accelerated pension benefit payment option for eligible persons. Upon the request of an eligible person, the System shall calculate, using actuarial tables and other assumptions adopted by the Board, an accelerated pension benefit payment amount and shall offer that eligible person the opportunity to irrevocably elect to have his or her automatic annual increases in retirement annuity calculated in accordance with the formula provided under subsection (b-5) and any increases in survivor's annuity payable to his or her survivor's annuity beneficiary calculated in accordance with the formula provided under subsection (b-6) in exchange for the accelerated pension benefit payment. The election under this subsection must be made before the eligible person receives the first payment of a retirement annuity otherwise payable under this Article.
    (b-5) Notwithstanding any other provision of law, the retirement annuity of a person who made the election under subsection (b) shall be subject to annual increases on the January 1 occurring either on or after the attainment of age 67 or the first anniversary of the annuity start date, whichever is later. Each annual increase shall be calculated at 1.5% of the originally granted retirement annuity.
    (b-6) Notwithstanding any other provision of law, a survivor's annuity payable to a survivor's annuity beneficiary of a person who made the election under subsection (b) shall be subject to annual increases on the January 1 occurring on or after the first anniversary of the commencement of the annuity. Each annual increase shall be calculated at 1.5% of the originally granted survivor's annuity.
    (c) If a person who has received an accelerated pension benefit payment returns to active service under this Article, then:
        (1) the calculation of any future automatic annual
    
increase in retirement annuity shall be calculated in accordance with the formula provided under subsection (b-5); and
        (2) the accelerated pension benefit payment may not
    
be repaid to the System.
    (d) As a condition of receiving an accelerated pension benefit payment, the accelerated pension benefit payment must be transferred into a tax qualified retirement plan or account. The accelerated pension benefit payment under this Section may be subject to withholding or payment of applicable taxes, but to the extent permitted by federal law, a person who receives an accelerated pension benefit payment under this Section must direct the System to pay all of that payment as a rollover into another retirement plan or account qualified under the Internal Revenue Code of 1986, as amended.
    (d-5) Upon receipt of a member's irrevocable election to receive an accelerated pension benefit payment under this Section, the System shall submit a voucher to the Comptroller for payment of the member's accelerated pension benefit payment. The Comptroller shall transfer the amount of the voucher to the System, and the System shall transfer the amount into a member's eligible retirement plan or qualified account.
    (e) The Board shall adopt any rules, including emergency rules, necessary to implement this Section.
    (f) No provision of this Section shall be interpreted in a way that would cause the applicable System to cease to be a qualified plan under the Internal Revenue Code of 1986.

40 ILCS 5/14-148.1

    (40 ILCS 5/14-148.1)
    Sec. 14-148.1. Mistake in benefit. If the System mistakenly sets any benefit at an incorrect amount, it shall recalculate the benefit as soon as may be practicable after the mistake is discovered.
    If the benefit was mistakenly set too low, the System shall make a lump sum payment to the recipient of an amount equal to the difference between the benefits that should have been paid and those actually paid.
    If the benefit was mistakenly set too high, the System may recover the amount overpaid from the recipient thereof, either directly or by deducting such amount from the remaining benefits payable to the recipient. However, if (1) the amount of the benefit was mistakenly set too high, and (2) the error was undiscovered for 3 years or longer, and (3) the error was not the result of incorrect information supplied by the affected member or beneficiary, then upon discovery of the mistake the benefit shall be adjusted to the correct level, but the recipient of the benefit need not repay to the System the excess amounts received in error.
    This Section applies to all mistakes in benefit calculations that occur before, on, or after the effective date of this amendatory Act of the 98th General Assembly.

    None of the benefits provided for in this Article shall be paid to any person who otherwise would receive a survivor benefit who is convicted of any felony relating to or arising out of or in connection with the service of the employee from whom the benefit results.
    This Section shall not operate to impair any contract or vested right heretofore acquired under any law or laws continued in this Article nor to preclude the right to a refund, and for the changes under this amendatory Act of the 100th General Assembly, shall not impair any contract or vested right acquired by a survivor prior to the effective date of this amendatory Act of the 100th General Assembly.
    All future entrants entering service subsequent to July 9, 1955 shall be deemed to have consented to the provisions of this section as a condition of coverage, and all participants entering service subsequent to the effective date of this amendatory Act of the 100th General Assembly shall be deemed to have consented to the provisions of this amendatory Act as a condition of participation.

(Source: P.A. 86-272.)

40 ILCS 5/14-152.1

    (40 ILCS 5/14-152.1)
    Sec. 14-152.1. Application and expiration of new benefit increases.
    (a) As used in this Section, "new benefit increase" means an increase in the amount of any benefit provided under this Article, or an expansion of the conditions of eligibility for any benefit under this Article, that results from an amendment to this Code that takes effect after June 1, 2005 (the effective date of Public Act 94-4). "New benefit increase", however, does not include any benefit increase resulting from the changes made to Article 1 or this Article by Public Act 96-37, Public Act 100-23, Public Act 100-587, Public Act 100-611, Public Act 101-10, Public Act 101-610, Public Act 102-210, or this amendatory Act of the 102nd General Assembly.
    (b) Notwithstanding any other provision of this Code or any subsequent amendment to this Code, every new benefit increase is subject to this Section and shall be deemed to be granted only in conformance with and contingent upon compliance with the provisions of this Section.
    (c) The Public Act enacting a new benefit increase must identify and provide for payment to the System of additional funding at least sufficient to fund the resulting annual increase in cost to the System as it accrues.
    Every new benefit increase is contingent upon the General Assembly providing the additional funding required under this subsection. The Commission on Government Forecasting and Accountability shall analyze whether adequate additional funding has been provided for the new benefit increase and shall report its analysis to the Public Pension Division of the Department of Insurance. A new benefit increase created by a Public Act that does not include the additional funding required under this subsection is null and void. If the Public Pension Division determines that the additional funding provided for a new benefit increase under this subsection is or has become inadequate, it may so certify to the Governor and the State Comptroller and, in the absence of corrective action by the General Assembly, the new benefit increase shall expire at the end of the fiscal year in which the certification is made.
    (d) Every new benefit increase shall expire 5 years after its effective date or on such earlier date as may be specified in the language enacting the new benefit increase or provided under subsection (c). This does not prevent the General Assembly from extending or re-creating a new benefit increase by law.
    (e) Except as otherwise provided in the language creating the new benefit increase, a new benefit increase that expires under this Section continues to apply to persons who applied and qualified for the affected benefit while the new benefit increase was in effect and to the affected beneficiaries and alternate payees of such persons, but does not apply to any other person, including, without limitation, a person who continues in service after the expiration date and did not apply and qualify for the affected benefit while the new benefit increase was in effect.

    Sec. 15-107. Employee.
    (a) "Employee" means any member of the educational, administrative, secretarial, clerical, mechanical, labor or other staff of an employer whose employment is permanent and continuous or who is employed in a position in which services are expected to be rendered on a continuous basis for at least 4 months or one academic term, whichever is less, who (A) receives payment for personal services on a warrant issued pursuant to a payroll voucher certified by an employer and drawn by the State Comptroller upon the State Treasurer or by an employer upon trust, federal or other funds, or (B) is on a leave of absence without pay. Employment which is irregular, intermittent or temporary shall not be considered continuous for purposes of this paragraph.
    However, a person is not an "employee" if he or she:
        (1) is a student enrolled in and regularly attending
    
classes in a college or university which is an employer, and is employed on a temporary basis at less than full time;
        (2) is currently receiving a retirement annuity or a
    
disability retirement annuity under Section 15-153.2 from this System;
        (3) is on a military leave of absence;
        (4) is eligible to participate in the Federal Civil
    
Service Retirement System and is currently making contributions to that system based upon earnings paid by an employer;
        (5) is on leave of absence without pay for more than
    
60 days immediately following termination of disability benefits under this Article;
        (6) is hired after June 30, 1979 as a public service
    
employment program participant under the Federal Comprehensive Employment and Training Act and receives earnings in whole or in part from funds provided under that Act; or
        (7) is employed on or after July 1, 1991 to perform
    
services that are excluded by subdivision (a)(7)(f) or (a)(19) of Section 210 of the federal Social Security Act from the definition of employment given in that Section (42 U.S.C. 410).
    (b) Any employer may, by filing a written notice with the board, exclude from the definition of "employee" all persons employed pursuant to a federally funded contract entered into after July 1, 1982 with a federal military department in a program providing training in military courses to federal military personnel on a military site owned by the United States Government, if this exclusion is not prohibited by the federally funded contract or federal laws or rules governing the administration of the contract.
    (c) Any person appointed by the Governor under the Civil Administrative Code of Illinois is an employee, if he or she is a participant in this system on the effective date of the appointment.
    (d) A participant on lay-off status under civil service rules is considered an employee for not more than 120 days from the date of the lay-off.
    (e) A participant is considered an employee during (1) the first 60 days of disability leave, (2) the period, not to exceed one year, in which his or her eligibility for disability benefits is being considered by the board or reviewed by the courts, and (3) the period he or she receives disability benefits under the provisions of Section 15-152, workers' compensation or occupational disease benefits, or disability income under an insurance contract financed wholly or partially by the employer.
    (f) Absences without pay, other than formal leaves of absence, of less than 30 calendar days, are not considered as an interruption of a person's status as an employee. If such absences during any period of 12 months exceed 30 work days, the employee status of the person is considered as interrupted as of the 31st work day.
    (g) A staff member whose employment contract requires services during an academic term is to be considered an employee during the summer and other vacation periods, unless he or she declines an employment contract for the succeeding academic term or his or her employment status is otherwise terminated, and he or she receives no earnings during these periods.
    (h) An individual who was a participating employee employed in the fire department of the University of Illinois's Champaign-Urbana campus immediately prior to the elimination of that fire department and who immediately after the elimination of that fire department became employed by the fire department of the City of Urbana or the City of Champaign shall continue to be considered as an employee for purposes of this Article for so long as the individual remains employed as a firefighter by the City of Urbana or the City of Champaign. The individual shall cease to be considered an employee under this subsection (h) upon the first termination of the individual's employment as a firefighter by the City of Urbana or the City of Champaign.
    (i) An individual who is employed on a full-time basis as an officer or employee of a statewide teacher organization that serves System participants or an officer of a national teacher organization that serves System participants may participate in the System and shall be deemed an employee, provided that (1) the individual has previously earned creditable service under this Article, (2) the individual files with the System an irrevocable election to become a participant before January 5, 2012 (the effective date of Public Act 97-651), (3) the individual does not receive credit for that employment under any other Article of this Code, and (4) the individual first became a full-time employee of the teacher organization and becomes a participant before January 5, 2012 (the effective date of Public Act 97-651). An employee under this subsection (i) is responsible for paying to the System both (A) employee contributions based on the actual compensation received for service with the teacher organization and (B) employer contributions equal to the normal costs (as defined in Section 15-155) resulting from that service; all or any part of these contributions may be paid on the employee's behalf or picked up for tax purposes (if authorized under federal law) by the teacher organization.
    A person who is an employee as defined in this subsection (i) may establish service credit for similar employment prior to becoming an employee under this subsection by paying to the System for that employment the contributions specified in this subsection, plus interest at the effective rate from the date of service to the date of payment. However, credit shall not be granted under this subsection for any such prior employment for which the applicant received credit under any other provision of this Code, or during which the applicant was on a leave of absence under Section 15-113.2.
    (j) A person employed by the State Board of Higher Education in a position with the Illinois Century Network as of June 30, 2004 shall be considered to be an employee for so long as he or she remains continuously employed after that date by the Department of Central Management Services in a position with the Illinois Century Network, the Bureau of Communication and Computer Services, or, if applicable, any successor bureau or the Department of Innovation and Technology and meets the requirements of subsection (a).
    (k) The Board shall promulgate rules with respect to determining whether any person is an employee within the meaning of this Section. In the case of doubt as to whether any person is an employee within the meaning of this Section or any rule adopted by the Board, the decision of the Board shall be final.

    (a) "Earnings": Subject to Section 15-111.5, an amount paid for personal services equal to the sum of the basic compensation plus extra compensation for summer teaching, overtime or other extra service. For periods for which an employee receives service credit under subsection (c) of Section 15-113.1 or Section 15-113.2, earnings are equal to the basic compensation on which contributions are paid by the employee during such periods.

Upon payment of the employee contributions on transition pay, the corresponding employer contributions become an obligation of the State.
    (b) For a Tier 2 member, the annual earnings shall not exceed $106,800; however, that amount shall annually thereafter be increased by the lesser of (i) 3% of that amount, including all previous adjustments, or (ii) one half the annual unadjusted percentage increase (but not less than zero) in the consumer price index-u for the 12 months ending with the September preceding each November 1, including all previous adjustments.

    Sec. 15-112. Final rate of earnings. "Final rate of earnings":
    (a) This subsection (a) applies only to a Tier 1 member.
    For an employee who is paid on an hourly basis or who receives an annual salary in installments during 12 months of each academic year, the average annual earnings during the 48 consecutive calendar month period ending with the last day of final termination of employment or the 4 consecutive academic years of service in which the employee's earnings were the highest, whichever is greater. For any other employee, the average annual earnings during the 4 consecutive academic years of service in which his or her earnings were the highest. For an employee with less than 48 months or 4 consecutive academic years of service, the average earnings during his or her entire period of service. The earnings of an employee with more than 36 months of service under item (a) of Section 15-113.1 prior to the date of becoming a participant are, for such period, considered equal to the average earnings during the last 36 months of such service.
    (b) This subsection (b) applies to a Tier 2 member.
    For an employee who is paid on an hourly basis or who receives an annual salary in installments during 12 months of each academic year, the average annual earnings obtained by dividing by 8 the total earnings of the employee during the 96 consecutive months in which the total earnings were the highest within the last 120 months prior to termination.
    For any other employee, the average annual earnings during the 8 consecutive academic years within the 10 years prior to termination in which the employee's earnings were the highest. For an employee with less than 96 consecutive months or 8 consecutive academic years of service, whichever is necessary, the average earnings during his or her entire period of service.
    (c) For an employee on leave of absence with pay, or on leave of absence without pay who makes contributions during such leave, earnings are assumed to be equal to the basic compensation on the date the leave began.
    (d) For an employee on disability leave, earnings are assumed to be equal to the basic compensation on the date disability occurs or the average earnings during the 24 months immediately preceding the month in which disability occurs, whichever is greater.
    (e) For a Tier 1 member who retires on or after the effective date of this amendatory Act of 1997 with at least 20 years of service as a firefighter or police officer under this Article, the final rate of earnings shall be the annual rate of earnings received by the participant on his or her last day as a firefighter or police officer under this Article, if that is greater than the final rate of earnings as calculated under the other provisions of this Section.
    (f) If a Tier 1 member is an employee for at least 6 months during the academic year in which his or her employment is terminated, the annual final rate of earnings shall be 25% of the sum of (1) the annual basic compensation for that year, and (2) the amount earned during the 36 months immediately preceding that year, if this is greater than the final rate of earnings as calculated under the other provisions of this Section.
    (g) In the determination of the final rate of earnings for an employee, that part of an employee's earnings for any academic year beginning after June 30, 1997, which exceeds the employee's earnings with that employer for the preceding year by more than 20 percent shall be excluded; in the event that an employee has more than one employer this limitation shall be calculated separately for the earnings with each employer. In making such calculation, only the basic compensation of employees shall be considered, without regard to vacation or overtime or to contracts for summer employment. Beginning September 1, 2024, this subsection (g) also applies to an employee who has been employed at 1/2 time or less for 3 or more years.
    (h) The following are not considered as earnings in determining final rate of earnings: (1) severance or separation pay, (2) retirement pay, (3) payment for unused sick leave, and (4) payments from an employer for the period used in determining final rate of earnings for any purpose other than (i) services rendered, (ii) leave of absence or vacation granted during that period, and (iii) vacation of up to 56 work days allowed upon termination of employment; except that, if the benefit has been collectively bargained between the employer and the recognized collective bargaining agent pursuant to the Illinois Educational Labor Relations Act, payment received during a period of up to 2 academic years for unused sick leave may be considered as earnings in accordance with the applicable collective bargaining agreement, subject to the 20% increase limitation of this Section. Any unused sick leave considered as earnings under this Section shall not be taken into account in calculating service credit under Section 15-113.4.
    (i) Intermittent periods of service shall be considered as consecutive in determining final rate of earnings.

"Service for periods of military service": Those periods, not exceeding 5 years, during which a person served in the armed forces of the United States, of which all but 2 years must have immediately followed a period of employment with an employer under this System or the State Employees' Retirement System of Illinois; provided that the person received a discharge other than dishonorable and again became an employee under this System within one year after discharge. However, for the up to 2 years of military service not immediately following employment, the applicant must make contributions to the System equal to (1) 8% of the employee's basic compensation on the last date as a participating employee prior to such military service, or on the first date as a participating employee after such military service, whichever is greater, plus (2) an amount determined by the board to be equal to the employer's normal cost of the benefits accrued for such military service, plus (3) interest on items (1) and (2) at the effective rate from the later of the date of first membership in the System or the date of conclusion of military service to the date of payment.

In the case of an annuitant who applies for credit allowable under this Section for a period of military service that did not immediately follow employment, and who has made the required contributions for such credit, the annuity shall be recalculated to include the additional service credit, with the increase taking effect on the date the System received written notification of the annuitant's intent to purchase the credit, if payment of all the required contributions is made within 60 days of such notice, or else on the first annuity payment date following the date of payment of the required contributions. In calculating the automatic annual increase for an annuity that has been recalculated under this Section, the increase attributable to the additional service allowable under this amendatory Act of 1991 shall be included in the calculation of automatic annual increases accruing after the effective date of the recalculation.

Each employer shall certify to the board the number of days of unused sick leave accrued to the participant's credit on the date that the participant's status as an employee terminated. This period of unused sick leave shall not be considered in determining the date the retirement annuity begins.

"Service for unused sick leave": A participant who is an employee under this System or one of the other systems subject to Article 20 of this Code within 60 days immediately preceding the date on which his or her retirement annuity begins, is entitled to credit for service for that portion of unused sick leave earned in the course of employment with an employer and credited on the date of termination of employment by an employer for which payment is not received, in accordance with the following schedule: 30 through 90 full calendar days and 20 through 59 full work days of unused sick leave, 1/4 of a year of service; 91 through 180 full calendar days and 60 through 119 full work days, 1/2 of a year of service; 181 through 270 full calendar days and 120 through 179 full work days, 3/4 of a year of service; 271 through 360 full calendar days and 180 through 240 full work days, one year of service. Only uncompensated, unused sick leave earned in accordance with an employer's sick leave accrual policy generally applicable to employees or a class of employees shall be taken into account in calculating service credit under this Section. Any uncompensated, unused sick leave granted by an employer to facilitate the hiring, retirement, termination, or other special circumstances of an employee shall not be taken into account in calculating service credit under this Section. If a participant transfers from one employer to another, the unused sick leave credited by the previous employer shall be considered in determining service to be credited under this Section, even if the participant terminated service prior to the effective date of P.A. 86-272 (August 23, 1989); if necessary, the retirement annuity shall be recalculated to reflect such sick leave credit. Each employer shall certify to the board the number of days of unused sick leave accrued to the participant's credit on the date that the participant's status as an employee terminated. This period of unused sick leave shall not be considered in determining the date the retirement annuity begins.

    Sec. 15-134.5. Retirement program elections.
    (a) All participating employees are participants under the traditional benefit package prior to January 1, 1998.
    Effective as of the date that an employer elects, as described in Section 15-158.2, to offer to its employees the portable benefit package and the self-managed plan as alternatives to the traditional benefit package, each of that employer's eligible employees (as defined in subsection (b)) shall be given the choice to elect which retirement program he or she wishes to participate in with respect to all periods of covered employment occurring on and after the effective date of the employee's election. The retirement program election made by an eligible employee must be made in writing, in the manner prescribed by the System, and within the time period described in subsection (d) or (d-1).
    The employee election authorized by this Section is a one-time, irrevocable election. If an employee terminates employment after making the election provided under this subsection (a), then upon his or her subsequent re-employment with an employer the original election shall automatically apply to him or her, provided that the employer is then a participating employer as described in Section 15-158.2.
    An eligible employee who fails to make this election shall, by default, participate in the traditional benefit package.
    (b) "Eligible employee" means an employee (as defined in Section 15-107) who is either a currently eligible employee or a newly eligible employee. For purposes of this Section, a "currently eligible employee" is an employee who is employed by an employer on the effective date on which the employer offers to its employees the portable benefit package and the self-managed plan as alternatives to the traditional benefit package. A "newly eligible employee" is an employee who first becomes employed by an employer after the effective date on which the employer offers its employees the portable benefit package and the self-managed plan as alternatives to the traditional benefit package. A newly eligible employee participates in the traditional benefit package until he or she makes an election to participate in the portable benefit package or the self-managed plan. If an employee does not elect to participate in the portable benefit package or the self-managed plan, he or she shall continue to participate in the traditional benefit package by default.
    (c) An eligible employee who at the time he or she is first eligible to make the election described in subsection (a) does not have sufficient age and service to qualify for a retirement annuity under Section 15-135 may elect to participate in the traditional benefit package, the portable benefit package, or the self-managed plan. An eligible employee who has sufficient age and service to qualify for a retirement annuity under Section 15-135 at the time he or she is first eligible to make the election described in subsection (a) may elect to participate in the traditional benefit package or the portable benefit package, but may not elect to participate in the self-managed plan.
    (d) A currently eligible employee must make this election within one year after the effective date of the employer's adoption of the self-managed plan.
    A newly eligible employee must make this election within 6 months after the date on which the System receives the report of status certification from the employer. If an employee elects to participate in the self-managed plan, no employer contributions shall be remitted to the self-managed plan when the employee's account balance transfer is made. Employer contributions to the self-managed plan shall commence as of the first pay period that begins after the System receives the employee's election.
    (d-1) A newly eligible employee who, prior to the effective date of this amendatory Act of the 91st General Assembly, fails to make the election within the period provided under subsection (d) and participates by default in the traditional benefit package may make a late election to participate in the portable benefit package or the self-managed plan instead of the traditional benefit package at any time within 6 months after the effective date of this amendatory Act of the 91st General Assembly.
    (e) If a currently eligible employee elects the portable benefit package, that election shall not become effective until the one-year anniversary of the date on which the election is filed with the System, provided the employee remains continuously employed by the employer throughout the one-year waiting period, and any benefits payable to or on account of the employee before such one-year waiting period has ended shall not be determined under the provisions applicable to the portable benefit package but shall instead be determined in accordance with the traditional benefit package. If a currently eligible employee who has elected the portable benefit package terminates employment covered by the System before the one-year waiting period has ended, then no benefits shall be determined under the portable benefit package provisions while he or she is inactive in the System and upon re-employment with an employer covered by the System he or she shall begin a new one-year waiting period before the provisions of the portable benefit package become effective.
    (f) An eligible employee shall be provided with written information prepared or prescribed by the System which describes the employee's retirement program choices. The eligible employee shall be offered an opportunity to receive counseling from the System prior to making his or her election. This counseling may consist of videotaped materials, group presentations, individual consultation with an employee or authorized representative of the System in person or by telephone or other electronic means, or any combination of these methods.

    (b) The annuity payment period shall begin on the date specified by the participant or the recipient of a disability retirement annuity submitting a written application. For a participant, the date on which the annuity payment period begins shall not be prior to termination of employment or more than one year before the application is received by the board; however, if the participant is not an employee of an employer participating in this System or in a participating system as defined in Article 20 of this Code on April 1 of the calendar year next following the calendar year in which the participant attains the age specified under Section 401(a)(9) of the Internal Revenue Code of 1986, as amended, the annuity payment period shall begin on that date regardless of whether an application has been filed. For a recipient of a disability retirement annuity, the date on which the annuity payment period begins shall not be prior to the discontinuation of the disability retirement annuity under Section 15-153.2.
    (c) An annuity is not payable if the amount provided under Section 15-136 is less than $10 per month.

    Sec. 15-136. Retirement annuities - Amount. The provisions of this Section 15-136 apply only to those participants who are participating in the traditional benefit package or the portable benefit package and do not apply to participants who are participating in the self-managed plan.
    (a) The amount of a participant's retirement annuity, expressed in the form of a single-life annuity, shall be determined by whichever of the following rules is applicable and provides the largest annuity:
    Rule 1: The retirement annuity shall be 1.67% of final rate of earnings for each of the first 10 years of service, 1.90% for each of the next 10 years of service, 2.10% for each year of service in excess of 20 but not exceeding 30, and 2.30% for each year in excess of 30; or for persons who retire on or after January 1, 1998, 2.2% of the final rate of earnings for each year of service.
    Rule 2: The retirement annuity shall be the sum of the following, determined from amounts credited to the participant in accordance with the actuarial tables and the effective rate of interest in effect at the time the retirement annuity begins:
        (i) the normal annuity which can be provided on an
    
actuarially equivalent basis, by the accumulated normal contributions as of the date the annuity begins;
        (ii) an annuity from employer contributions of an
    
amount equal to that which can be provided on an actuarially equivalent basis from the accumulated normal contributions made by the participant under Section 15-113.6 and Section 15-113.7 plus 1.4 times all other accumulated normal contributions made by the participant; and
        (iii) the annuity that can be provided on an
    
actuarially equivalent basis from the entire contribution made by the participant under Section 15-113.3.
    With respect to a police officer or firefighter who retires on or after August 14, 1998, the accumulated normal contributions taken into account under clauses (i) and (ii) of this Rule 2 shall include the additional normal contributions made by the police officer or firefighter under Section 15-157(a).
    The amount of a retirement annuity calculated under this Rule 2 shall be computed solely on the basis of the participant's accumulated normal contributions, as specified in this Rule and defined in Section 15-116. Neither an employee or employer contribution for early retirement under Section 15-136.2 nor any other employer contribution shall be used in the calculation of the amount of a retirement annuity under this Rule 2.
    This amendatory Act of the 91st General Assembly is a clarification of existing law and applies to every participant and annuitant without regard to whether status as an employee terminates before the effective date of this amendatory Act.
    This Rule 2 does not apply to a person who first becomes an employee under this Article on or after July 1, 2005.
    Rule 3: The retirement annuity of a participant who is employed at least one-half time during the period on which his or her final rate of earnings is based, shall be equal to the participant's years of service not to exceed 30, multiplied by (1) $96 if the participant's final rate of earnings is less than $3,500, (2) $108 if the final rate of earnings is at least $3,500 but less than $4,500, (3) $120 if the final rate of earnings is at least $4,500 but less than $5,500, (4) $132 if the final rate of earnings is at least $5,500 but less than $6,500, (5) $144 if the final rate of earnings is at least $6,500 but less than $7,500, (6) $156 if the final rate of earnings is at least $7,500 but less than $8,500, (7) $168 if the final rate of earnings is at least $8,500 but less than $9,500, and (8) $180 if the final rate of earnings is $9,500 or more, except that the annuity for those persons having made an election under Section 15-154(a-1) shall be calculated and payable under the portable retirement benefit program pursuant to the provisions of Section 15-136.4.
    Rule 4: A participant who is at least age 50 and has 25 or more years of service as a police officer or firefighter, and a participant who is age 55 or over and has at least 20 but less than 25 years of service as a police officer or firefighter, shall be entitled to a retirement annuity of 2 1/4% of the final rate of earnings for each of the first 10 years of service as a police officer or firefighter, 2 1/2% for each of the next 10 years of service as a police officer or firefighter, and 2 3/4% for each year of service as a police officer or firefighter in excess of 20. The retirement annuity for all other service shall be computed under Rule 1. A Tier 2 member is eligible for a retirement annuity calculated under Rule 4 only if that Tier 2 member meets the service requirements for that benefit calculation as prescribed under this Rule 4 in addition to the applicable age requirement under subsection (a-10) of Section 15-135.
    For purposes of this Rule 4, a participant's service as a firefighter shall also include the following:
        (i) service that is performed while the person is an
    
employee under subsection (h) of Section 15-107; and
        (ii) in the case of an individual who was a
    
participating employee employed in the fire department of the University of Illinois's Champaign-Urbana campus immediately prior to the elimination of that fire department and who immediately after the elimination of that fire department transferred to another job with the University of Illinois, service performed as an employee of the University of Illinois in a position other than police officer or firefighter, from the date of that transfer until the employee's next termination of service with the University of Illinois.
    (b) For a Tier 1 member, the retirement annuity provided under Rules 1 and 3 above shall be reduced by 1/2 of 1% for each month the participant is under age 60 at the time of retirement. However, this reduction shall not apply in the following cases:
        (1) For a disabled participant whose disability
    
benefits have been discontinued because he or she has exhausted eligibility for disability benefits under clause (6) of Section 15-152;
        (2) For a participant who has at least the number of
    
years of service required to retire at any age under subsection (a) of Section 15-135; or
        (3) For that portion of a retirement annuity which
    
has been provided on account of service of the participant during periods when he or she performed the duties of a police officer or firefighter, if these duties were performed for at least 5 years immediately preceding the date the retirement annuity is to begin.
    (b-5) The retirement annuity of a Tier 2 member who is retiring under Rule 1 or 3 after attaining age 62 with at least 10 years of service credit shall be reduced by 1/2 of 1% for each full month that the member's age is under age 67.
    (c) The maximum retirement annuity provided under Rules 1, 2, 4, and 5 shall be the lesser of (1) the annual limit of benefits as specified in Section 415 of the Internal Revenue Code of 1986, as such Section may be amended from time to time and as such benefit limits shall be adjusted by the Commissioner of Internal Revenue, and (2) 80% of final rate of earnings.
    (d) A Tier 1 member whose status as an employee terminates after August 14, 1969 shall receive automatic increases in his or her retirement annuity as follows:
    Effective January 1 immediately following the date the retirement annuity begins, the annuitant shall receive an increase in his or her monthly retirement annuity of 0.125% of the monthly retirement annuity provided under Rule 1, Rule 2, Rule 3, or Rule 4 contained in this Section, multiplied by the number of full months which elapsed from the date the retirement annuity payments began to January 1, 1972, plus 0.1667% of such annuity, multiplied by the number of full months which elapsed from January 1, 1972, or the date the retirement annuity payments began, whichever is later, to January 1, 1978, plus 0.25% of such annuity multiplied by the number of full months which elapsed from January 1, 1978, or the date the retirement annuity payments began, whichever is later, to the effective date of the increase.
    The annuitant shall receive an increase in his or her monthly retirement annuity on each January 1 thereafter during the annuitant's life of 3% of the monthly annuity provided under Rule 1, Rule 2, Rule 3, or Rule 4 contained in this Section. The change made under this subsection by P.A. 81-970 is effective January 1, 1980 and applies to each annuitant whose status as an employee terminates before or after that date.
    Beginning January 1, 1990, all automatic annual increases payable under this Section shall be calculated as a percentage of the total annuity payable at the time of the increase, including all increases previously granted under this Article.
    The change made in this subsection by P.A. 85-1008 is effective January 26, 1988, and is applicable without regard to whether status as an employee terminated before that date.
    (d-5) A retirement annuity of a Tier 2 member shall receive annual increases on the January 1 occurring either on or after the attainment of age 67 or the first anniversary of the annuity start date, whichever is later. Each annual increase shall be calculated at 3% or one half the annual unadjusted percentage increase (but not less than zero) in the consumer price index-u for the 12 months ending with the September preceding each November 1, whichever is less, of the originally granted retirement annuity. If the annual unadjusted percentage change in the consumer price index-u for the 12 months ending with the September preceding each November 1 is zero or there is a decrease, then the annuity shall not be increased.
    (e) If, on January 1, 1987, or the date the retirement annuity payment period begins, whichever is later, the sum of the retirement annuity provided under Rule 1 or Rule 2 of this Section and the automatic annual increases provided under the preceding subsection or Section 15-136.1, amounts to less than the retirement annuity which would be provided by Rule 3, the retirement annuity shall be increased as of January 1, 1987, or the date the retirement annuity payment period begins, whichever is later, to the amount which would be provided by Rule 3 of this Section. Such increased amount shall be considered as the retirement annuity in determining benefits provided under other Sections of this Article. This paragraph applies without regard to whether status as an employee terminated before the effective date of this amendatory Act of 1987, provided that the annuitant was employed at least one-half time during the period on which the final rate of earnings was based.
    (f) A participant is entitled to such additional annuity as may be provided on an actuarially equivalent basis, by any accumulated additional contributions to his or her credit. However, the additional contributions made by the participant toward the automatic increases in annuity provided under this Section shall not be taken into account in determining the amount of such additional annuity.
    (g) If, (1) by law, a function of a governmental unit, as defined by Section 20-107 of this Code, is transferred in whole or in part to an employer, and (2) a participant transfers employment from such governmental unit to such employer within 6 months after the transfer of the function, and (3) the sum of (A) the annuity payable to the participant under Rule 1, 2, or 3 of this Section (B) all proportional annuities payable to the participant by all other retirement systems covered by Article 20, and (C) the initial primary insurance amount to which the participant is entitled under the Social Security Act, is less than the retirement annuity which would have been payable if all of the participant's pension credits validated under Section 20-109 had been validated under this system, a supplemental annuity equal to the difference in such amounts shall be payable to the participant.
    (h) On January 1, 1981, an annuitant who was receiving a retirement annuity on or before January 1, 1971 shall have his or her retirement annuity then being paid increased $1 per month for each year of creditable service. On January 1, 1982, an annuitant whose retirement annuity began on or before January 1, 1977, shall have his or her retirement annuity then being paid increased $1 per month for each year of creditable service.
    (i) On January 1, 1987, any annuitant whose retirement annuity began on or before January 1, 1977, shall have the monthly retirement annuity increased by an amount equal to 8¢ per year of creditable service times the number of years that have elapsed since the annuity began.
    (j) The changes made to this Section by this amendatory Act of the 101st General Assembly apply retroactively to January 1, 2011.

    (40 ILCS 5/15-136.1) (from Ch. 108 1/2, par. 15-136.1)
    Sec. 15-136.1. Retirement annuities - Supplemental annuity. (a) An annuitant whose status as an employee terminated before August 15, 1969 with at least 15 years of service is entitled to a supplemental annuity as follows:
    Effective January 1, nearest the first anniversary of retirement, or January 1, nearest the annuitant's 65th birthday, whichever is later, the annuitant shall receive a supplemental annuity of 0.125% of the monthly retirement annuity which was provided under Rule 1, Rule 2, or Rule 3 of Section 15-136, multiplied by the number of full months which elapsed from the date of retirement through December 31, 1971, 0.1667% of such annuity multiplied by the number of full months which elapsed from January 1, 1972 through December 31, 1977, and 0.25% of such annuity multiplied by the number of full months which elapsed from January 1, 1978 to the effective date of the supplemental annuity.
    On each January 1 thereafter during the annuitant's lifetime, he or she shall receive an additional supplemental annuity of 3% of the monthly annuity provided under Rule 1, Rule 2 or Rule 3 of Section 15-136. The change made in this Section by P.A. 81-970 is effective January 1, 1980 and applies to each annuitant whose status as an employee terminated before August 15, 1969.
    The supplemental annuity is payable only if the annuitant files with the board, an agreement to pay to the system, an amount equal to 1% of his or her monthly final rate of earnings multiplied by the number of years of service credited on the date of retirement. The payment shall be made in a lump sum, and if it is received by the board more than 30 days after the effective date of the supplemental annuity, the supplemental annuity shall be deferred to the first day of the month following receipt of the payment.
    (b) Each annuitant, whose status as an employee terminated before August 15, 1969 with less than 15 years of service, is entitled to a monthly supplemental annuity effective January 1, 1984 or January 1 nearest the first anniversary of retirement or January 1 nearest his or her 65th birthday, whichever is later, of 3% of the monthly annuity which was provided by Rule 1, Rule 2, or Rule 3 of Section 15-136. On each January 1 thereafter during the lifetime of the annuitant, he or she shall be entitled to an additional monthly supplemental annuity of 3% of the monthly annuity which was provided by Rule 1, Rule 2, or Rule 3 of Section 15-136.
    Beginning January 1, 1990, all automatic annual increases payable under this Section shall be calculated as a percentage of the total annuity payable at the time of the increase, including all increases previously granted under this Article.

    (40 ILCS 5/15-136.2) (from Ch. 108 1/2, par. 15-136.2)
    Sec. 15-136.2. Early retirement without discount. A participant whose retirement annuity begins after June 1, 1981 and on or before September 1, 2002 and within six months of the last day of employment for which retirement contributions were required, may elect at the time of application to make a one time employee contribution to the System and thereby avoid the early retirement reduction in retirement annuity specified under subsection (b) of Section 15-136. The exercise of the election shall obligate the last employer to also make a one time non-refundable contribution to the System.
    The one time employee and employer contributions shall be a percentage of the retiring participant's highest full time annual salary rate during the academic years which were considered in determining his or her final rate of earnings, or if not full time then the full time equivalent. The employee contribution rate shall be 7% multiplied by the lesser of the following 2 sums: (1) the number of years that the participant is less than age 60; or (2) the number of years that the participant's creditable service is less than 35 years. The employer contribution shall be at the rate of 20% for each year the participant is less than age 60. The employer shall pay the employer contribution from the same source of funds which is used in paying earnings to employees.
    Upon receipt of the application and election, the System shall determine the one time employee and employer contributions. The provisions of this Section shall not be applicable until all the above outlined contributions have been received by the System; however, the date such contributions are received shall not be considered in determining the effective date of retirement.
    Employee and employer contributions under this Section shall be used only to eliminate the reduction for early retirement under Rules 1 and 3 of Section 15-136 and shall not be used in calculating annuities under Rules 2 or 4 set forth in Section 15-136. This amendatory Act of the 91st General Assembly is a clarification of existing law and applies to every participant and annuitant without regard to whether status as an employee terminates before the effective date of this amendatory Act.
    For persons who apply to the Board after the effective date of this amendatory Act of 1993 and before July 1, 1993, requesting a retirement annuity to begin no earlier than July 1, 1993 and no later than June 30, 1994, the employer shall pay both the employee and employer contributions required under this Section.
    The number of employees retiring under this Section in any fiscal year may be limited at the option of the employer to no less than 15% of those eligible. The right to elect early retirement without discount shall be allocated among those applying on the basis of seniority in the service of the last employer.

    Sec. 15-136.3. Minimum retirement annuity.
    (a) Beginning January 1, 1997, any person who is receiving a monthly retirement annuity under this Article which, after inclusion of (1) all one-time and automatic annual increases to which the person is entitled, (2) any supplemental annuity payable under Section 15-136.1, and (3) any amount deducted under Section 15-138 or 15-140 to provide a reversionary annuity, is less than the minimum monthly retirement benefit amount specified in subsection (b) of this Section, shall be entitled to a monthly supplemental payment equal to the difference.
    (b) For purposes of the calculation in subsection (a), the minimum monthly retirement benefit amount is the sum of $25 for each year of service credit, up to a maximum of 30 years of service.
    (c) This Section applies to all persons receiving a retirement annuity under this Article, without regard to whether or not employment terminated prior to the effective date of this Section.

40 ILCS 5/15-136.4

    (40 ILCS 5/15-136.4)
    Sec. 15-136.4. Retirement and Survivor Benefits Under Portable Benefit Package.
    (a) This Section 15-136.4 describes the form of annuity and survivor benefits available to a participant who has elected the portable benefit package and has completed the one-year waiting period required under subsection (e) of Section 15-134.5. For purposes of this Section, the term "eligible spouse" means the husband or wife of a participant to whom the participant is married on the date the participant's annuity payment period begins, provided however, that if the participant should die prior to the commencement of retirement annuity benefits, then "eligible spouse" means the husband or wife, if any, to whom the participant was married throughout the one-year period preceding the date of his or her death.
    (b) This subsection (b) describes the normal form of annuity payable to a participant subject to this Section 15-136.4. If the participant is unmarried on the date his or her annuity payment period begins, then the annuity payments shall be made in the form of a single-life annuity as described in Section 15-118. If the participant is married on the date his or her annuity payments commence, then the annuity payments shall be paid in the form of a qualified joint and survivor annuity that is the actuarial equivalent of the single-life annuity. Under the "qualified joint and survivor annuity", a reduced amount shall be paid to the participant for his or her lifetime and his or her eligible spouse, if surviving at the participant's death, shall be entitled to receive thereafter a lifetime survivorship annuity in a monthly amount equal to 50% of the reduced monthly amount that was payable to the participant. The last payment of a qualified joint and survivor annuity shall be made as of the first day of the month in which the death of the survivor occurs.
    (c) Instead of the normal form of annuity that would be paid under subsection (b), a participant may elect in writing within the 180-day period prior to the date his or her annuity payments commence to waive the normal form of annuity payment and receive an optional form of payment as described in subsection (h). If the participant is married and elects an optional form of payment under subsection (h) other than a joint and survivor annuity with the eligible spouse designated as the contingent annuitant, then such election shall require the consent of his or her eligible spouse in the manner described in subsection (d). At any time during the 180-day period preceding the date the participant's payment period begins, the participant may revoke the optional form of payment elected under this subsection (c) and reinstate coverage under the qualified joint and survivor annuity without the spouse's consent, but an election to revoke the optional form elected and elect a new optional form of payment or designate a different contingent annuitant shall not be effective without the eligible spouse's consent.
    (d) The eligible spouse's consent to any election made pursuant to this Section that requires the eligible spouse's consent shall be in writing and shall acknowledge the effect of the consent. In addition, the eligible spouse's signature on the written consent must be witnessed by a notary public. The eligible spouse's consent need not be obtained if the system is satisfied that there is no eligible spouse, that the eligible spouse cannot be located, or because of any other relevant circumstances. An eligible spouse's consent under this Section is valid only with respect to the specified optional form of payment and, if applicable, contingent annuitant designated by the participant. If the optional form of payment or the contingent annuitant is subsequently changed (other than by a revocation of the optional form of payment and reinstatement of the qualified joint and survivor annuity), a new consent by the eligible spouse is required. The eligible spouse's consent to an election made by a participant pursuant to this Section, once made, may not be revoked by the eligible spouse.
    (e) Within a reasonable period of time preceding the date a participant's annuity commences, a participant shall be supplied with a written explanation of (1) the terms and conditions of the normal form single-life annuity and qualified joint and survivor annuity, (2) the participant's right to elect a single-life annuity or an optional form of payment under subsection (h) subject to his or her eligible spouse's consent, if applicable, and (3) the participant's right to reinstate coverage under the qualified joint and survivor annuity prior to his or her annuity commencement date by revoking an election of an optional form of payment under subsection (h).
    (f) If a married participant with at least 1.5 years of service dies prior to commencing retirement annuity payments and prior to taking a refund under Section 15-154, his or her eligible spouse is entitled to receive a pre-retirement survivor annuity, if there is not then in effect a waiver of the pre-retirement survivor annuity. The pre-retirement survivor annuity payable under this subsection shall be a monthly annuity payable for the eligible spouse's life, commencing as of the beginning of the month next following the later of the date of the participant's death or the date the participant would have first met the eligibility requirements for retirement, and continuing through the beginning of the month in which the death of the eligible spouse occurs. The monthly amount payable to the spouse under the pre-retirement survivor annuity shall be equal to the monthly amount that would be payable as a survivor annuity under the qualified joint and survivor annuity described in subsection (b) if: (1) in the case of a participant who dies on or after the date on which the participant has met the eligibility requirements for retirement, the participant had retired with an immediate qualified joint and survivor annuity on the day before the participant's date of death; or (2) in the case of a participant who dies before the earliest date on which the participant would have met the eligibility requirements for retirement age, the participant had separated from service on the date of death, survived to the earliest retirement age based on service prior to his or her death, retired with an immediate qualified joint and survivor annuity at the earliest retirement age, and died on the day after the day on which the participant would have attained the earliest retirement age.
    (g) A married participant who has not retired may elect at any time to waive the pre-retirement survivor annuity described in subsection (f). Any such election shall require the consent of the participant's eligible spouse in the manner described in subsection (d). A waiver of the pre-retirement survivor annuity shall increase the lump sum death benefit payable under subsection (b) of Section 15-141. Prior to electing any waiver of the pre-retirement survivor annuity, the participant shall be provided with a written explanation of (1) the terms and conditions of the pre-retirement survivor annuity and the death benefits payable from the system both with and without the pre-retirement survivor annuity, (2) the participant's right to elect a waiver of the pre-retirement survivor annuity coverage subject to his or her spouse's consent, and (3) the participant's right to reinstate pre-retirement survivor annuity coverage at any time by revoking a prior waiver of such coverage.
    (h) By filing a timely election with the system, a participant who will be eligible to receive a retirement annuity under this Section may waive the normal form of annuity payment described in subsection (b), subject to obtaining the consent of his or her eligible spouse, if applicable, and elect to receive any one of the following optional forms of payment:
        (1) Joint and Survivor Annuity Options: The
    
participant may elect to receive a reduced annuity payable for his or her life and to have a lifetime survivorship annuity in a monthly amount equal to 50%, 75%, or 100% (as elected by the participant) of that reduced monthly amount, to be paid after the participant's death to his or her contingent annuitant, if the contingent annuitant is alive at the time of the participant's death.
        (2) Single-Life Annuity Option (optional for married
    
participants). The participant may elect to receive a single-life annuity payable for his or her life only.
        (3) Lump sum retirement benefit. The participant may
    
elect to receive a lump sum retirement benefit that is equal to the amount of a refund payable under Section 15-154(a-2).
All joint and survivor annuity forms shall be in an amount that is the actuarial equivalent of the single-life annuity.
    For the purposes of this Section, the term "contingent annuitant" means the beneficiary who is designated by a participant at the time the participant elects a joint and survivor annuity to receive the lifetime survivorship annuity in the event the beneficiary survives the participant at the participant's death.
    (i) Under no circumstances may an option be elected, changed, or revoked after the date the participant's retirement annuity commences.
    (j) An election made pursuant to subsection (h) shall become inoperative if the participant or the contingent annuitant dies before the date the participant's annuity payments commence, or if the eligible spouse's consent is required and not given.
    (k) (Blank).
    (l) The automatic annual increases described in subsection (d) of Section 15-136 shall apply to retirement benefits under the portable benefit package and the automatic annual increases described in subsection (j) of Section 15-145 shall apply to survivor benefits under the portable benefit package.

    (a) If an annuitant returns to employment for an employer within 60 days after the beginning of the retirement annuity payment period, the retirement annuity shall be cancelled, and the annuitant shall refund to the System the total amount of the retirement annuity payments which he or she received. If the retirement annuity is cancelled, the participant shall continue to participate in the System.
    (b) If an annuitant retires prior to age 60 and receives or becomes entitled to receive during any month compensation in excess of the monthly retirement annuity (including any automatic annual increases) for services performed after the date of retirement for any employer under this System, that portion of the monthly retirement annuity provided by employer contributions shall not be payable.
    If an annuitant retires at age 60 or over and receives or becomes entitled to receive during any academic year compensation in excess of the difference between his or her highest annual earnings prior to retirement and his or her annual retirement annuity computed under Rule 1, Rule 2, Rule 3, or Rule 4 of Section 15-136, or under Section 15-136.4, for services performed after the date of retirement for any employer under this System, that portion of the monthly retirement annuity provided by employer contributions shall be reduced by an amount equal to the compensation that exceeds such difference.
    However, any remuneration received for serving as a member of the Illinois Educational Labor Relations Board shall be excluded from "compensation" for the purposes of this subsection (b), and serving as a member of the Illinois Educational Labor Relations Board shall not be deemed to be a return to employment for the purposes of this Section. This provision applies without regard to whether service was terminated prior to the effective date of this amendatory Act of 1991.
    "Academic year", as used in this subsection (b), means the 12-month period beginning September 1.
    (c) If an employer certifies that an annuitant has been reemployed on a permanent and continuous basis or in a position in which the annuitant is expected to serve for at least 9 months, the annuitant shall resume his or her status as a participating employee and shall be entitled to all rights applicable to participating employees upon filing with the board an election to forgo all annuity payments during the period of reemployment. Upon subsequent retirement, the retirement annuity shall consist of the annuity which was terminated by the reemployment, plus the additional retirement annuity based upon service granted during the period of reemployment, but the combined retirement annuity shall not exceed the maximum annuity applicable on the date of the last retirement.
    The total service and earnings credited before and after the initial date of retirement shall be considered in determining eligibility of the employee or the employee's beneficiary to benefits under this Article, and in calculating final rate of earnings.
    In determining the death benefit payable to a beneficiary of an annuitant who again becomes a participating employee under this Section, accumulated normal and additional contributions shall be considered as the sum of the accumulated normal and additional contributions at the date of initial retirement and the accumulated normal and additional contributions credited after that date, less the sum of the annuity payments received by the annuitant.
    The survivors insurance benefits provided under Section 15-145 shall not be applicable to an annuitant who resumes his or her status as a participating employee, unless the annuitant, at the time of initial retirement, has a survivors insurance beneficiary who could qualify for such benefits or the annuitant repaid the survivors insurance contribution refund or additional annuity under subsection (c-5) of Section 15-154.
    If the participant's employment is terminated because of circumstances other than death before 9 months from the date of reemployment, the provisions of this Section regarding resumption of status as a participating employee shall not apply. The normal and survivors insurance contributions which are deducted during this period shall be refunded to the annuitant without interest, and subsequent benefits under this Article shall be the same as those which were applicable prior to the date the annuitant resumed employment.
    The amendments made to this Section by this amendatory Act of the 91st General Assembly apply without regard to whether the annuitant was in service on or after the effective date of this amendatory Act.

    Sec. 15-139.5. Return to work by affected annuitant; notice and contribution by employer.
    (a) An employer who employs or re-employs a person receiving a retirement annuity from the System in an academic year beginning on or after August 1, 2013 must notify the System of that employment within 60 days after employing the annuitant. The notice must include a summary of the contract of employment or specify the rate of compensation and the anticipated length of employment of that annuitant. The notice must specify whether the annuitant will be compensated from federal, corporate, foundation, or trust funds or grants of State funds that identify the principal investigator by name. The notice must include the employer's determination of whether or not the annuitant is an "affected annuitant" as defined in subsection (b).
    The employer must also record, document, and certify to the System (i) the amount of compensation paid to the annuitant for employment during the academic year, and (ii) the amount of that compensation, if any, that comes from either federal, corporate, foundation, or trust funds or grants of State funds that identify the principal investigator by name.
    As used in this Section, "academic year" means the 12-month period beginning September 1.
    For the purposes of this Section, an annuitant whose employment by an employer extends over more than one academic year shall be deemed to be re-employed by that employer in each of those academic years.
    The System may specify the time, form, and manner of providing the determinations, notifications, certifications, and documentation required under this Section.
    (b) A person receiving a retirement annuity from the System becomes an "affected annuitant" on the first day of the academic year following the academic year in which the annuitant first meets the following conditions:
        (1) (Blank).
        (2) While receiving a retirement annuity under this
    
Article, the annuitant was employed on or after August 1, 2013 by one or more employers under this Article and received or became entitled to receive during an academic year compensation for that employment in excess of 40% of his or her highest annual earnings prior to retirement; except that compensation paid from federal, corporate, foundation, or trust funds or grants of State funds that identify the principal investigator by name is excluded.
        (3) The annuitant received an annualized retirement
    
annuity under this Article of at least $10,000.
    A person who becomes an affected annuitant remains an affected annuitant, except for (i) any period during which the person returns to active service and does not receive a retirement annuity from the System or (ii) any period on or after the effective date of this amendatory Act of the 100th General Assembly during which an annuitant received an annualized retirement annuity under this Article that is less than $10,000.
    (c) It is the obligation of the employer to determine whether an annuitant is an affected annuitant before employing the annuitant. For that purpose the employer may require the annuitant to disclose and document his or her relevant prior employment and earnings history. Failure of the employer to make this determination correctly and in a timely manner or to include this determination with the notification required under subsection (a) does not excuse the employer from making the contribution required under subsection (e).
    The System may assist the employer in determining whether a person is an affected annuitant. The System shall inform the employer if it discovers that the employer's determination is inconsistent with the employment and earnings information in the System's records.
    (d) Upon the request of an annuitant, the System shall certify to the annuitant or the employer the following information as reported by the employers, as that information is indicated in the records of the System: (i) the annuitant's highest annual earnings prior to retirement, (ii) the compensation paid for that employment in each academic year, and (iii) whether any of that employment or compensation has been certified to the System as being paid from federal, corporate, foundation, or trust funds or grants of State funds that identify the principal investigator by name. The System shall only be required to certify information that is received from the employers.
    (e) In addition to the requirements of subsection (a), an employer who employs an affected annuitant must pay to the System an employer contribution in the amount and manner provided in this Section, unless the annuitant is compensated by that employer solely from federal, corporate, foundation, or trust funds or grants of State funds that identify the principal investigator by name.
    The employer contribution required under this Section for employment of an affected annuitant in an academic year shall be equal to 12 times the amount of the gross monthly retirement annuity payable to the annuitant for the month in which the first paid day of that employment in that academic year occurs, after any reduction in that annuity that may be imposed under subsection (b) of Section 15-139.
    If an affected annuitant is employed by more than one employer in an academic year, the employer contribution required under this Section shall be divided among those employers in proportion to their respective portions of the total compensation paid to the affected annuitant for that employment during that academic year.
    If the System determines that an employer, without reasonable justification, has failed to make the determination of affected annuitant status correctly and in a timely manner, or has failed to notify the System or to correctly document or certify to the System any of the information required by this Section, and that failure results in a delayed determination by the System that a contribution is payable under this Section, then the amount of that employer's contribution otherwise determined under this Section shall be doubled.
    The System shall deem a failure to correctly determine the annuitant's status to be justified if the employer establishes to the System's satisfaction that the employer, after due diligence, made an erroneous determination that the annuitant was not an affected annuitant due to reasonable reliance on false or misleading information provided by the annuitant or another employer, or an error in the annuitant's official employment or earnings records.
    (f) Whenever the System determines that an employer is liable for a contribution under this Section, it shall so notify the employer and certify the amount of the contribution. The employer may pay the required contribution without interest at any time within one year after receipt of the certification. If the employer fails to pay within that year, then interest shall be charged at a rate equal to the System's prescribed rate of interest, compounded annually from the 366th day after receipt of the certification from the System. Payment must be concluded within 2 years after receipt of the certification by the employer. If the employer fails to make complete payment, including applicable interest, within 2 years, then the System may, after giving notice to the employer, certify the delinquent amount to the State Comptroller, and the Comptroller shall thereupon deduct the certified delinquent amount from State funds payable to the employer and pay them instead to the System.
    (g) If an employer is required to make a contribution to the System as a result of employing an affected annuitant and the annuitant later elects to forgo his or her annuity in that same academic year pursuant to subsection (c) of Section 15-139, then the required contribution by the employer shall be waived, and if the contribution has already been paid, it shall be refunded to the employer without interest.
    (h) Notwithstanding any other provision of this Article, the employer contribution required under this Section shall not be included in the determination of any benefit under this Article or any other Article of this Code, regardless of whether the annuitant returns to active service, and is in addition to any other State or employer contribution required under this Article.
    (i) Notwithstanding any other provision of this Section to the contrary, if an employer employs an affected annuitant in order to continue critical operations in the event of either an employee's unforeseen illness, accident, or death or a catastrophic incident or disaster, then, for one and only one academic year, the employer is not required to pay the contribution set forth in this Section for that annuitant. The employer shall, however, immediately notify the System upon employing a person subject to this subsection (i). For the purposes of this subsection (i), "critical operations" means teaching services, medical services, student welfare services, and any other services that are critical to the mission of the employer.
    (j) This Section shall be applied and coordinated with the regulatory obligations contained in the State Universities Civil Service Act. This Section shall not apply to an annuitant if the employer of that annuitant provides documentation to the System that (1) the annuitant is employed in a status appointment position, as that term is defined in 80 Ill. Adm. Code 250.80, and (2) due to obligations contained under the State Universities Civil Service Act, the employer does not have the ability to limit the earnings or duration of employment for the annuitant while employed in the status appointment position.

    (a) The beneficiary of a participant under the traditional benefit package is entitled to a death benefit equal to the sum of (1) the employee's accumulated normal and additional contributions on the date of death, (2) the employee's accumulated survivors insurance contributions on the date of death, if a survivors insurance benefit is not payable, (3) an amount equal to the employee's final rate of earnings, but not more than $5,000, if (i) the beneficiary, under rules of the board, was dependent upon the participant, (ii) the participant was a participating employee immediately prior to his or her death, and (iii) a survivors insurance benefit is not payable, and (4) $2,500 if (i) the beneficiary was not dependent upon the participant, (ii) the participant was a participating employee immediately prior to his or her death, and (iii) a survivors insurance benefit is not payable.
    (b) If the participant has elected to participate in the portable benefit package and has completed the one-year waiting period required under subsection (e) of Section 15-134.5, the death benefit shall be equal to the employee's accumulated normal and additional contributions on the date of death plus, if the employee died with 1.5 or more years of service for employment as defined in Section 15-113.1, employer contributions in an amount equal to the sum of the accumulated normal and additional contributions; except that if a pre-retirement survivor annuity is payable under Section 15-136.4, the death benefit payable under this paragraph shall be reduced, but to not less than zero, by the actuarial value of the benefit payable to the surviving spouse. If the recipient of a pre-retirement survivor annuity dies before an amount equal to all accumulated normal and additional contributions as of the date of death have been paid out, the remaining difference shall be paid to the member's beneficiary. The primary beneficiary of the participant must be his or her spouse unless the spouse has consented to the designation of another beneficiary in the manner described in subsection (d) of Section 15-136.4.
    (c) If payments are made under any State or federal workers' compensation or occupational diseases law because of the death of an employee, the portion of the death benefit payable from employer contributions shall be reduced by the total amount of the payments.

    If a deceased participant has specified in a written notice on file with the board prior to his or her death, or if the participant has not so specified, but the beneficiary specifies in the application for the death benefit that the benefit be paid as an annuity or as a designated cash payment plus an annuity, it shall be paid in the manner thus specified, unless the annuity is less than $10 per month, in which case the death benefit shall be paid in a single cash sum. If the death benefit is paid as an annuity, the beneficiary may elect to take an amount not in excess of $500 in a single cash sum. The annuity payable to a beneficiary shall be the actuarial equivalent of the death benefit, determined as of the participant's date of death, on the basis of the age of the beneficiary at that time.
    The beneficiary annuity payment period shall begin on the day following the death of the deceased and shall terminate on the date of the beneficiary's death. If the beneficiary may receive the death benefit in a single cash sum, but elects to receive an annuity, he or she may, within one year after the death of the participant or annuitant, revoke this election and receive in a single cash sum the excess of the amount of the death benefit upon which the annuity was based over the sum of the annuity payments received.

    Sec. 15-145. Survivors insurance benefits; conditions and amounts.
    (a) The survivors insurance benefits provided under this Section shall be payable to the eligible survivors of a Tier 1 member covered under the traditional benefit package upon the death of (1) a participating employee with at least 1 1/2 years of service, (2) a participant who terminated employment with at least 10 years of service, and (3) an annuitant in receipt of a retirement annuity or disability retirement annuity under this Article.
    Service under the State Employees' Retirement System of Illinois, the Teachers' Retirement System of the State of Illinois and the Public School Teachers' Pension and Retirement Fund of Chicago shall be considered in determining eligibility for survivors benefits under this Section.
    If by law, a function of a governmental unit, as defined by Section 20-107, is transferred in whole or in part to an employer, and an employee transfers employment from this governmental unit to such employer within 6 months after the transfer of this function, the service credits in the governmental unit's retirement system which have been validated under Section 20-109 shall be considered in determining eligibility for survivors benefits under this Section.
    (b) A surviving spouse of a deceased participant, or of a deceased annuitant who did not take a refund or additional annuity consisting of accumulated survivors insurance contributions or who repaid the refund or additional annuity, shall receive a survivors annuity of 30% of the final rate of earnings. Payments shall begin on the day following the participant's or annuitant's death or the date the surviving spouse attains age 50, whichever is later, and continue until the death of the surviving spouse. The annuity shall be payable to the surviving spouse prior to attainment of age 50 if the surviving spouse has in his or her care a deceased participant's or annuitant's dependent unmarried child under age 18 (under age 22 if a full-time student) who is eligible for a survivors annuity.
    Remarriage of a surviving spouse prior to attainment of age 55 that occurs before the effective date of this amendatory Act of the 91st General Assembly shall disqualify him or her for the receipt of a survivors annuity until July 6, 2000.
    A surviving spouse whose survivors annuity has been terminated due to remarriage may apply for reinstatement of that annuity. The reinstated annuity shall begin to accrue on July 6, 2000, except that if, on July 6, 2000, the annuity is payable to an eligible surviving child or parent, payment of the annuity to the surviving spouse shall not be reinstated until the annuity is no longer payable to any eligible surviving child or parent. The reinstated annuity shall include any one-time or annual increases received prior to the date of termination, as well as any increases that would otherwise have accrued from the date of termination to the date of reinstatement. An eligible surviving spouse whose expectation of receiving a survivors annuity was lost due to remarriage before attainment of age 50 shall also be entitled to reinstatement under this subsection, but the resulting survivors annuity shall not begin to accrue sooner than upon the surviving spouse's attainment of age 50.
    The changes made to this subsection by this amendatory Act of the 92nd General Assembly (pertaining to remarriage prior to age 55 or 50) apply without regard to whether the deceased participant or annuitant was in service on or after the effective date of this amendatory Act.
    (c) Each dependent unmarried child under age 18 (under age 22 if a full-time student) of a deceased participant, or of a deceased annuitant who did not take a refund or additional annuity consisting of accumulated survivors insurance contributions or who repaid the refund or additional annuity, shall receive a survivors annuity equal to the sum of (1) 20% of the final rate of earnings, and (2) 10% of the final rate of earnings divided by the number of children entitled to this benefit. Payments shall begin on the day following the participant's or annuitant's death and continue until the child marries, dies, or attains age 18 (age 22 if a full-time student). If the child is in the care of a surviving spouse who is eligible for survivors insurance benefits, the child's benefit shall be paid to the surviving spouse.
    Each unmarried child over age 18 of a deceased participant or of a deceased annuitant who had a survivor's insurance beneficiary at the time of his or her retirement, and who was dependent upon the participant or annuitant by reason of a physical or mental disability which began prior to the date the child attained age 18, shall receive a survivor's annuity equal to the sum of (1) 20% of the final rate of earnings, and (2) 10% of the final rate of earnings divided by the number of children entitled to survivors benefits. Payments shall begin on the day following the participant's or annuitant's death and continue until the child marries, dies, or is no longer disabled. If the child is in the care of a surviving spouse who is eligible for survivors insurance benefits, the child's benefit may be paid to the surviving spouse. For the purposes of this Section, disability means inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment that can be expected to result in death or that has lasted or can be expected to last for a continuous period of at least one year.
    (d) Each dependent parent of a deceased participant, or of a deceased annuitant who did not take a refund or additional annuity consisting of accumulated survivors insurance contributions or who repaid the refund or additional annuity, shall receive a survivors annuity equal to the sum of (1) 20% of final rate of earnings, and (2) 10% of final rate of earnings divided by the number of parents who qualify for the benefit. Payments shall begin when the parent reaches age 55 or the day following the participant's or annuitant's death, whichever is later, and continue until the parent dies. Remarriage of a parent prior to attainment of age 55 shall disqualify the parent for the receipt of a survivors annuity.
    (e) In addition to the survivors annuity provided above, each survivors insurance beneficiary shall, upon death of the participant or annuitant, receive a lump sum payment of $1,000 divided by the number of such beneficiaries.
    (f) The changes made in this Section by Public Act 81-712 pertaining to survivors annuities in cases of remarriage prior to age 55 shall apply to each survivors insurance beneficiary who remarries after June 30, 1979, regardless of the date that the participant or annuitant terminated his employment or died.
    The change made to this Section by this amendatory Act of the 91st General Assembly, pertaining to remarriage prior to age 55, applies without regard to whether the deceased participant or annuitant was in service on or after the effective date of this amendatory Act of the 91st General Assembly.
    (g) On January 1, 1981, any person who was receiving a survivors annuity on or before January 1, 1971 shall have the survivors annuity then being paid increased by 1% for each full year which has elapsed from the date the annuity began. On January 1, 1982, any survivor whose annuity began after January 1, 1971, but before January 1, 1981, shall have the survivor's annuity then being paid increased by 1% for each year which has elapsed from the date the survivor's annuity began. On January 1, 1987, any survivor who began receiving a survivor's annuity on or before January 1, 1977, shall have the monthly survivor's annuity increased by $1 for each full year which has elapsed since the date the survivor's annuity began.
    (h) If the sum of the lump sum and total monthly survivor benefits payable under this Section upon the death of a participant amounts to less than the sum of the death benefits payable under items (2) and (3) of Section 15-141, the difference shall be paid in a lump sum to the beneficiary of the participant who is living on the date that this additional amount becomes payable.
    (i) If the sum of the lump sum and total monthly survivor benefits payable under this Section upon the death of an annuitant receiving a retirement annuity or disability retirement annuity amounts to less than the death benefit payable under Section 15-142, the difference shall be paid to the beneficiary of the annuitant who is living on the date that this additional amount becomes payable.
    (j) Effective on the later of (1) January 1, 1990, or (2) the January 1 on or next after the date on which the survivor annuity begins, if the deceased member died while receiving a retirement annuity, or in all other cases the January 1 nearest the first anniversary of the date the survivor annuity payments begin, every survivors insurance beneficiary shall receive an increase in his or her monthly survivors annuity of 3%. On each January 1 after the initial increase, the monthly survivors annuity shall be increased by 3% of the total survivors annuity provided under this Article, including previous increases provided by this subsection. Such increases shall apply to the survivors insurance beneficiaries of each participant and annuitant, whether or not the employment status of the participant or annuitant terminates before the effective date of this amendatory Act of 1990. This subsection (j) also applies to persons receiving a survivor annuity under the portable benefit package.
    (k) If the Internal Revenue Code of 1986, as amended, requires that the survivors benefits be payable at an age earlier than that specified in this Section the benefits shall begin at the earlier age, in which event, the survivor's beneficiary shall be entitled only to that amount which is equal to the actuarial equivalent of the benefits provided by this Section.
    (l) The changes made to this Section and Section 15-131 by this amendatory Act of 1997, relating to benefits for certain unmarried children who are full-time students under age 22, apply without regard to whether the deceased member was in service on or after the effective date of this amendatory Act of 1997. These changes do not authorize the repayment of a refund or a re-election of benefits, and any benefit or increase in benefits resulting from these changes is not payable retroactively for any period before the effective date of this amendatory Act of 1997.

Survivor eligibility, vesting, and conditions for a survivor's insurance annuity and lump sum payment amount payable to a survivor's insurance beneficiary of a deceased Tier 2 member shall be determined under the provisions of this Article applicable to survivor's insurance beneficiaries of a deceased Tier 1 member; however, the amount of a survivor's insurance annuity, including the annual increases thereon, shall be calculated pursuant to this Section. The initial survivor's insurance annuity of a survivors insurance beneficiary of a Tier 2 annuitant shall be in the amount of 66 2/3% of the Tier 2 member's retirement annuity at the date of death. In the case of the death of a Tier 2 member who has not retired, eligibility for a survivor's insurance benefit shall be determined by the applicable Section of this Article. The initial benefit shall be 66 2/3% of the earned annuity without a reduction due to age. A survivor's insurance annuity shall be increased (1) on each January 1 occurring on or after the commencement of the annuity if the deceased Tier 2 member died while receiving a retirement annuity or (2) in other cases, on each January 1 occurring after the first anniversary of the commencement of the benefit. Each annual increase shall be calculated at 3% or one half the annual unadjusted percentage increase (but not less than zero) in the consumer price index-u for the 12 months ending with the September preceding each November 1, whichever is less, of the originally granted survivor's insurance annuity. If the annual unadjusted percentage change in the consumer price index-u for the 12 months ending with the September preceding each November 1 is zero or there is a decrease, then the survivor's insurance annuity shall not be increased. A beneficiary of a Tier 2 member who elects the Portable Benefit Package provided under this Article shall not be eligible for the survivor's insurance annuity that is provided under this Section. If 2 or more persons are eligible to receive survivor's insurance annuities as provided under this Section based on the same deceased Tier 2 member, the calculation of the survivor's insurance annuities shall be based on the total calculation of the survivor's insurance annuity and divided pro rata. The changes made to this Section by this amendatory Act of the 98th General Assembly are a clarification of existing law and are intended to be retroactive to the effective date of Public Act 96-889, notwithstanding the provisions of Section 1-103.1 of this Code.

    (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.

    (b) The maximum total survivors annuity payable on account of the death of any person occurring after retirement or after termination of his or her employee status shall be the lesser of: (1) 80% of the final rate of earnings; (2) (A) $400 per month if one survivors insurance beneficiary is entitled to a survivors annuity, or (B) $600 per month if there are 2 or more such beneficiaries; or (3) 80% of the retirement annuity payable to the annuitant at the date of retirement under the provisions of Rule 1, Rule 2, or Rule 3 of Section 15-136, or 80% of the retirement annuity which would have been payable to the participant upon attainment of the minimum age at which the penalty for early retirement would not be applicable or the date of death, whichever is later, based upon credits earned as of the date of death.
    (c) The maximum total survivors annuity payable on account of the death of any person whose death occurs while in receipt of a disability retirement annuity under Section 15-153.2 shall be the lesser of (1) 80% of his or her final rate of earnings, (2) (A) $400 per month if one survivors insurance beneficiary is entitled to a survivors annuity, or (B) $600 per month if 2 or more survivors insurance beneficiaries qualify for this benefit, or (3) 80% of the retirement annuity which would have been payable upon attainment of the age at which the penalty for early retirement would not be applicable or the date of death, whichever is later, based upon the participant's credits on the date of death, or 80% of the disability retirement annuity whichever is greater.
    (d) If the minimum annuity provided under Section 15-146 exceeds the maximum annuity provided under this Section, the minimum annuity shall be payable.
    (e) 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.
    (f) If a survivors insurance beneficiary qualifies for a survivors or widows annuity because of pension credits established by the participant or annuitant in another system covered by Article 20, and the combined survivors annuities exceed the highest survivors annuity which could be provided by either system based upon the combined pension credits, the survivors annuity payable by this system shall be reduced to that amount which, when added to the survivors annuity payable by the other system, would equal this highest survivors annuity. If the other system has a similar provision for adjustment of the survivors annuity, the respective proportional survivors annuities shall be reduced proportionately according to the ratio which the amount of each proportional survivors annuity bears to the aggregate of all proportional survivors annuities. If a survivors annuity is payable by another system covered by Article 20, and the survivor elects to waive the survivors annuity and accept a lump sum payment or death benefit in lieu of the survivors annuity, this system shall, for the purpose of adjusting the survivors annuity under this subsection, assume that the survivor was entitled to a survivors annuity which, in accordance with actuarial tables of this system, is the actuarial equivalent of the amount of the lump sum payment or death benefit.
    (g) The total monthly survivors annuity payable to the beneficiaries of any annuitant who terminated employment before July 14, 1959 and whose death occurs after September 16, 1977 shall not exceed $200.
    (h) Whenever a reduction in the survivors annuity is made as authorized above, the survivors annuity to each dependent parent shall be proportionately reduced or eliminated, and if further reduction is necessary, the survivors annuity payable to every other person shall be proportionately decreased.

    Sec. 15-150. Disability benefits; eligibility. A participant may be granted a disability benefit if: (1) while a participating employee, he or she becomes physically or mentally incapacitated and unable to perform the duties of his or her assigned position for any period exceeding 60 days; and (2) the employee had completed 2 years of service at the time of disability, unless the disability is a result of an accident or the employee is a police officer who qualifies for the calculation under subsection (b) of Section 15-153.
    An employee shall be considered disabled only during the period for which the board determines, based upon the evidence listed below, that the employee is unable to reasonably perform the duties of his or her assigned position as a result of a physical or mental disability. This determination shall be based upon:
        (i) a written certificate from one or more licensed
    
and practicing physicians appointed by or acceptable to the board, stating that the employee is disabled and unable to reasonably perform the duties of his or her assigned position;
        (ii) a written certificate from the employer stating
    
that the employee is unable to perform the duties of his or her assigned position and, if the employee is a police officer, the employer's position on whether the disability qualifies as a line of duty disability;
        (iii) any other medical examinations, hospital
    
records, laboratory results, or other information necessary for determining the employment capacity and condition of the employee; and
        (iv) if the employee is a police officer applying
    
for a line of duty disability, a written certification from one or more licensed and practicing physicians appointed by or acceptable to the board, stating that the disability qualifies as a line of duty disability under subsection (b) of Section 15-153.
    The board shall prescribe rules governing the filing, investigation, control, and supervision of disability claims. Costs incurred by a claimant in connection with completing a claim for disability benefits shall be paid (A) by the claimant, in the case of the one required medical examination, medical certificate, and employer's certificate and any other requirements generally imposed by the board on all disability benefit claimants; and (B) by the System, in the case of any additional medical examination or other additional requirement imposed on a particular claimant that is not imposed generally on all disability benefit claimants.
    Pregnancy and childbirth shall be considered a disability.
    The same application shall be used to determine eligibility for the calculation of disability benefits under subsection (a) or subsection (b) of Section 15-153.

However, no benefits shall be payable covering a period of more than 30 days prior to the receipt of a written application unless the board finds good cause for the delay in filing the application. The recurrence within 30 days of a former disability shall be considered a continuation of the disability. If a disabled participant returns to his or her assigned position and within 30 days again becomes disabled from the same cause, the previous period of disability shall be considered in determining the date benefits may begin, and the amount of the benefit shall be based upon the basic compensation on the date the participant first became disabled from this cause.

If the disability was caused by an on-the-job accident, and the participant is granted workers' compensation or occupational disease payments from the employer or the State of Illinois, the limitation in clause (6) shall not be applicable.
    Service and earnings credits under the State Employees' Retirement System of Illinois and the Teachers' Retirement System of the State of Illinois shall be considered in determining the employee's eligibility for, and the duration of disability benefits.
    If, by law, a function of a governmental unit, as defined by Section 20-107 is transferred in whole or in part to an employer and an employee transfers employment from the governmental unit to such employer within 6 months after the transfer of this function, the pension credits in the governmental unit's retirement system which have been validated under Section 20-109, shall be treated the same as pension credits in this Section in determining an employee's eligibility for, and the duration of disability benefits.

    Sec. 15-153. Disability benefits; amount.
    (a) Except as provided in subsection (b), the disability benefit shall be the greater of (1) 50% of the basic compensation which would have been paid had the participant continued in service for the entire period during which disability benefits are payable, excluding wage or salary increases subsequent to the date of disability or extra prospective earnings on a summer teaching contract or other extra service not yet entered upon or (2) 50% of the participant's average earnings during the 24 months immediately preceding the month in which disability occurs. In determining the disability benefit, the basic compensation of a participating employee on leave of absence or on lay-off status shall be assumed to be equal to his or her basic compensation on the date the leave of absence or lay-off begins.
    (b) In lieu of the amount of the disability benefit otherwise provided for in subsection (a) of this Section, for a participant who is employed as a police officer and who incurs a line of duty disability, the disability benefit under this Section shall be the greater of: (1) 65% of the basic compensation that would have been paid had the participant continued in employment for the entire period during which disability benefits are payable, excluding wage or salary increases subsequent to the date of disability; or (2) 65% of the participant's average earnings during the 24 months immediately preceding the month in which disability occurs. In determining the disability benefit, the basic compensation of a participating employee on leave of absence or on lay-off status shall be assumed to be equal to his or her basic compensation on the date the leave of absence or lay-off begins.
    Any police officer who suffers a heart attack or stroke as a result of the performance and discharge of police duty shall be considered to have been injured in the performance of an act of duty and shall be eligible for the calculation of benefits provided for under this subsection (b).
    A police officer shall be considered to be in the performance of an act of duty while on any assignment approved by the police officer's chief, whether the assignment is on or off the employer's property.
    The changes made to this Section shall apply to participants whose line of duty disability occurred on or after January 1, 2022.
    For the purposes of this Section, "line of duty disability" means that, as the result of sickness, accident, or injury incurred in or resulting from the performance of an act of duty, the police officer is found to be physically or mentally disabled for employment as a police officer so as to render necessary his or her suspension or retirement from employment as a police officer or is found to be unable to perform his or her duties as a police officer by reason of heart disease, stroke, tuberculosis, or any disease of the lungs or respiratory tract, resulting from employment as a police officer.
    If the disability benefit is 50% of basic compensation under subsection (a) or 65% of basic compensation under subsection (b), payments during the academic year shall accrue over the period that the basic compensation would have been paid had the participant continued in service. If the disability benefit is 50% under subsection (a) or 65% under subsection (b) of the average earnings of the participant during the 24 months immediately preceding the month in which disability occurs, payments during the year shall accrue over a period of 12 months. Disability benefits shall be paid as of the end of each calendar month during which payments accrue. Payments for fractional parts of a month shall be determined by prorating the total amount payable for the full month on the basis of days elapsing during the month. Any disability benefit accrued but unpaid on the death of a participant shall be paid to the participant's beneficiary.

    Sec. 15-153.1. Disability benefits - Reduction. (a) If a participant receiving disability benefits under this Article earns compensation from any source for personal or professional services in excess of the amount of the disability benefit, the disability benefit shall be reduced by the excess of the earnings over the benefit.
    (b) If a participant receiving disability benefits under this Article receives disability income under an insurance contract financed wholly or partially by the employer, the disability benefit shall be reduced by the amount so received.
    (c) In determining the monthly benefits payable under this Article, a deduction shall be made equivalent to any benefits payable to any employee under any State or Federal Worker's Compensation or Occupational Diseases Acts for any period for which disability benefits are payable. However, no deduction shall be made in the case of payment for medical, surgical and hospital services and artificial members or appliances, fixed statutory payments for the loss of any bodily member, or the permanent and complete loss of use of 100% of any bodily member, payments for the loss of industrial vision or redemption awards payable prior to the date monthly disability benefits first become payable. If the benefits deductible under this paragraph are stated as a specified amount per week for a designated calendar period, then the monthly amounts shall, for purposes of this Section, be 4 1/3 times such weekly amount.
    For any calendar month during which the amount of benefits deductible when thus computed on the monthly basis exceeds the amount of the monthly benefit otherwise payable under this Article for that month, no monthly disability benefit shall be payable under this Article. For any calendar month in which the amount of benefits deductible when computed on a monthly basis is less than the monthly disability benefit payable for that month, such lesser amount shall be deducted from the monthly disability benefit payable for that month. Lump sum awards provided for the payment in advance of workers' compensation benefits which are definitely allocable to specific weeks in a calendar period shall be deducted on the same basis as if the award had been payable on a weekly basis.
    If such workers' compensation is not allocable to any specific calendar period, including redemption awards payable subsequent to the date monthly disability benefits first become payable, an equivalent monthly amount of such awards shall be computed for the purposes of this Section as 4 1/3 times the amount of the weekly workers' compensation benefit provided by the applicable statute for the participant and his or her dependents. The total workers' compensation awards shall be divided by such computed equivalent monthly amounts to determine the number of months and fractions of months during which monthly disability benefits shall be reduced.

    Sec. 15-153.2. Disability retirement annuity.
    (a) This subsection (a) applies to a participant receiving benefits calculated under subsection (a) of Section 15-153. A participant whose disability benefits are discontinued under the provisions of clause (6) of Section 15-152 and who is not a participant in the optional retirement plan established under Section 15-158.2 is entitled to a disability retirement annuity of 35% of the basic compensation which was payable to the participant at the time that disability began, provided that the board determines that the participant has a medically determinable physical or mental impairment that prevents him or her from engaging in any substantial gainful activity, and which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.
    (b) This subsection (b) applies to a participant receiving benefits calculated under subsection (b) of Section 15-153. A participant whose disability benefits are discontinued under clause (6) of Section 15-152 and who is not a participant in the optional retirement plan established under Section 15-158.2 is entitled to a disability retirement annuity of 65% of the basic compensation that was payable to the participant at the time that disability began, provided that the board determines that the participant has a medically determinable physical or mental impairment that prevents him or her from engaging in any substantial gainful activity and can be expected to result in death or has lasted or can be expected to last for a continuous period of not less than 12 months.
    (c) The board's determination of whether a participant is disabled shall be based upon:
        (i) a written certificate from one or more licensed
    
and practicing physicians appointed by or acceptable to the board, stating that the participant is unable to engage in any substantial gainful activity; and
        (ii) any other medical examinations, hospital
    
records, laboratory results, or other information necessary for determining the employment capacity and condition of the participant.
    The terms "medically determinable physical or mental impairment" and "substantial gainful activity" shall have the meanings ascribed to them in the federal Social Security Act, as now or hereafter amended, and the regulations issued thereunder.
    (d) The disability retirement annuity payment period shall begin immediately following the expiration of the disability benefit payments under clause (6) of Section 15-152 and shall be discontinued for a recipient of a disability retirement annuity when (1) the physical or mental impairment no longer prevents the recipient from engaging in any substantial gainful activity, (2) the recipient dies, (3) the recipient elects to receive a retirement annuity under Sections 15-135 and 15-136, (4) the recipient refuses to submit to a reasonable physical examination by a physician approved by the board, or (5) the recipient fails to provide an earnings verification necessary to determine continuance of benefits. If a person's disability retirement annuity is discontinued under clause (1), all rights and credits accrued in the system on the date that the disability retirement annuity began shall be restored, and the disability retirement annuity paid shall be considered as disability payments under clause (6) of Section 15-152.
    (e) The board shall adopt rules governing the filing, investigation, control, and supervision of disability retirement annuity claims. Costs incurred by a claimant in connection with completing a claim for a disability retirement annuity shall be paid: (A) by the claimant in the case of the one required medical examination, medical certificate, and any other requirements generally imposed by the board on all disability retirement annuity claimants; and (B) by the System in the case of any additional medical examination or other additional requirement imposed on a particular claimant that is not imposed generally on all disability retirement annuity claimants.

    Sec. 15-154. Refunds.
    (a) A participant whose status as an employee is terminated, regardless of cause, or who has been on lay off status for more than 120 days, and who is not on leave of absence, is entitled to a refund of contributions upon application; except that not more than one such refund application may be made during any academic year.
    Except as set forth in subsections (a-1) and (a-2), the refund shall be the sum of the accumulated normal, additional, and survivors insurance contributions, plus the entire contribution made by the participant under Section 15-113.3, less the amount of interest credited on these contributions each year in excess of 4 1/2% of the amount on which interest was calculated.
    (a-1) A person who elects, in accordance with the requirements of Section 15-134.5, to participate in the portable benefit package and who becomes a participating employee under that retirement program upon the conclusion of the one-year waiting period applicable to the portable benefit package election shall have his or her refund calculated in accordance with the provisions of subsection (a-2).
    (a-2) The refund payable to a participant described in subsection (a-1) shall be the sum of the participant's accumulated normal and additional contributions, as defined in Sections 15-116 and 15-117, plus the entire contribution made by the participant under Section 15-113.3. If the participant terminates with 5 or more years of service for employment as defined in Section 15-113.1, he or she shall also be entitled to a distribution of employer contributions in an amount equal to the sum of the accumulated normal and additional contributions, as defined in Sections 15-116 and 15-117.
    (b) Upon acceptance of a refund, the participant forfeits all accrued rights and credits in the System, and if subsequently reemployed, the participant shall be considered a new employee subject to all the qualifying conditions for participation and eligibility for benefits applicable to new employees. If such person again becomes a participating employee and continues as such for 2 years, or is employed by an employer and participates for at least 2 years in the Federal Civil Service Retirement System, all such rights, credits, and previous status as a participant shall be restored upon repayment of the amount of the refund, together with compound interest thereon from the date the refund was issued to the date of repayment at the rate of 6% per annum through August 31, 1982, and at the effective rates after that date. When a participant in the portable benefit package who received a refund which included a distribution of employer contributions repays a refund pursuant to this Section, one-half of the amount repaid shall be deemed the member's reinstated accumulated normal and additional contributions and the other half shall be allocated as an employer contribution to the System, except that any amount repaid for previously purchased military service credit under Section 15-113.3 shall be accounted for as such.
    (c) Except as otherwise provided under subsection (c-5), if a participant covered under the traditional benefit package has made survivors insurance contributions, but has no survivors insurance beneficiary upon retirement, he or she shall be entitled to elect a refund of the accumulated survivors insurance contributions, or to elect an additional annuity the value of which is equal to the accumulated survivors insurance contributions. This election must be made prior to the date the person's retirement annuity is approved by the System.
    (c-5) Notwithstanding subsection (c), an annuitant who retired prior to June 1, 2011 and made the election under subsection (c), and who thereafter became, and remains, either:
        (1) a party to a civil union or a party to a legal
    
relationship that is recognized as a civil union or marriage under the Illinois Religious Freedom Protection and Civil Union Act on or after June 1, 2011; or
        (2) a party to a marriage under the Illinois
    
Marriage and Dissolution of Marriage Act on or after February 26, 2014; or
        (3) a party to a marriage, civil union or other legal
    
relationship that, at the time it was formed, was not legally recognized in Illinois but was subsequently recognized as a civil union or marriage under the Illinois Religious Freedom Protection and Civil Union Act on or after June 1, 2011, a marriage under the Illinois Marriage and Dissolution of Marriage Act on or after February 26, 2014, or both;
may make a one-time, irrevocable election to repay the refund or additional annuity payments received under subsection (c), together with compound interest thereon at the actuarially assumed rate of return from the date the refund was issued or the date each additional annuity payment was issued to the date of repayment. The annuitant shall submit proof of party status for item (1), (2), or (3) in the form of a valid marriage certificate or a civil union certificate with any additional requirements the Board prescribes by rulemaking. The election must be received by the System (i) within a period of one year beginning 5 months after the effective date of this amendatory Act of the 99th General Assembly and (ii) prior to the date of death of the annuitant.
    To the extent permitted under the Internal Revenue Code of 1986, as amended, the full repayment shall be made within a period beginning on the date of the election and ending on the earlier of the 24th month thereafter or the date of the annuitant's death. If an annuitant fails to make the repayment within the required period, any payments made shall be returned, without interest, to the annuitant (or to the annuitant's estate if the payments ceased due to death), and survivors insurance benefits under Section 15-145 shall not be payable upon the annuitant's death.
    Upon such repayment, all forfeited survivors insurance benefit rights and credits under Section 15-145 shall be restored. This repayment right shall not alter or modify any eligibility requirement for survivors insurance beneficiaries under this Article applicable upon the annuitant's death. The repayment shall be irrevocable. No person shall have a claim or right to the repaid amounts in a manner not otherwise provided for under this Article in the event that: the marriage, civil union, or other legal relationship described in this subsection is dissolved, annulled, or declared invalid by a court of competent jurisdiction; or the other party to the marriage, civil union, or other legal relationship predeceases the annuitant or otherwise fails to qualify as a survivors insurance beneficiary upon the annuitant's death.
    For purposes of this subsection (c-5), the term "annuitant" shall include an annuitant who resumed his or her status as a participating employee under Section 15-139(c).
    (d) A participant, upon application, is entitled to a refund of his or her accumulated additional contributions attributable to the additional contributions described in the last sentence of subsection (c) of Section 15-157. Upon the acceptance of such a refund of accumulated additional contributions, the participant forfeits all rights and credits which may have accrued because of such contributions.
    (e) A participant who terminates his or her employee status and elects to waive service credit under Section 15-154.2, is entitled to a refund of the accumulated normal, additional and survivors insurance contributions, if any, which were credited the participant for this service, or to an additional annuity the value of which is equal to the accumulated normal, additional and survivors insurance contributions, if any; except that not more than one such refund application may be made during any academic year. Upon acceptance of this refund, the participant forfeits all rights and credits accrued because of this service.
    (f) If a police officer or firefighter receives a retirement annuity under Rule 1 or 3 of Section 15-136, he or she shall be entitled at retirement to a refund of the difference between his or her accumulated normal contributions and the normal contributions which would have accumulated had such person filed a waiver of the retirement formula provided by Rule 4 of Section 15-136.
    (g) If, at the time of retirement, a participant would be entitled to a retirement annuity under Rule 1, 2, 3, 4, or 5 of Section 15-136, or under Section 15-136.4, that exceeds the maximum specified in clause (1) of subsection (c) of Section 15-136, he or she shall be entitled to a refund of the employee contributions, if any, paid under Section 15-157 after the date upon which continuance of such contributions would have otherwise caused the retirement annuity to exceed this maximum, plus compound interest at the effective rates.

    (a-1) For State fiscal years 2012 through 2045, the minimum contribution to the System to be made by the State for each fiscal year shall be an amount determined by the System to be sufficient to bring the total assets of the System up to 90% of the total actuarial liabilities of the System by the end of State fiscal year 2045. In making these determinations, the required State contribution shall be calculated each year as a level percentage of payroll over the years remaining to and including fiscal year 2045 and shall be determined under the projected unit credit actuarial cost method.
    For each of State fiscal years 2018, 2019, and 2020, the State shall make an additional contribution to the System equal to 2% of the total payroll of each employee who is deemed to have elected the benefits under Section 1-161 or who has made the election under subsection (c) of Section 1-161.
    A change in an actuarial or investment assumption that increases or decreases the required State contribution and first applies in State fiscal year 2018 or thereafter shall be implemented in equal annual amounts over a 5-year period beginning in the State fiscal year in which the actuarial change first applies to the required State contribution.
    A change in an actuarial or investment assumption that increases or decreases the required State contribution and first applied to the State contribution in fiscal year 2014, 2015, 2016, or 2017 shall be implemented:
        (i) as already applied in State fiscal years before
    
2018; and
        (ii) in the portion of the 5-year period beginning in
    
the State fiscal year in which the actuarial change first applied that occurs in State fiscal year 2018 or thereafter, by calculating the change in equal annual amounts over that 5-year period and then implementing it at the resulting annual rate in each of the remaining fiscal years in that 5-year period.
    For State fiscal years 1996 through 2005, the State contribution to the System, as a percentage of the applicable employee payroll, shall be increased in equal annual increments so that by State fiscal year 2011, the State is contributing at the rate required under this Section.
    Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2006 is $166,641,900.
    Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2007 is $252,064,100.
    For each of State fiscal years 2008 through 2009, the State contribution to the System, as a percentage of the applicable employee payroll, shall be increased in equal annual increments from the required State contribution for State fiscal year 2007, so that by State fiscal year 2011, the State is contributing at the rate otherwise required under this Section.
    Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2010 is $702,514,000 and shall be made from the State Pensions Fund and proceeds of bonds sold in fiscal year 2010 pursuant to Section 7.2 of the General Obligation Bond Act, less (i) the pro rata share of bond sale expenses determined by the System's share of total bond proceeds, (ii) any amounts received from the General Revenue Fund in fiscal year 2010, (iii) any reduction in bond proceeds due to the issuance of discounted bonds, if applicable.
    Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2011 is the amount recertified by the System on or before April 1, 2011 pursuant to Section 15-165 and shall be made from the State Pensions Fund and proceeds of bonds sold in fiscal year 2011 pursuant to Section 7.2 of the General Obligation Bond Act, less (i) the pro rata share of bond sale expenses determined by the System's share of total bond proceeds, (ii) any amounts received from the General Revenue Fund in fiscal year 2011, and (iii) any reduction in bond proceeds due to the issuance of discounted bonds, if applicable.
    Beginning in State fiscal year 2046, the minimum State contribution for each fiscal year shall be the amount needed to maintain the total assets of the System at 90% of the total actuarial liabilities of the System.
    Amounts received by the System pursuant to Section 25 of the Budget Stabilization Act or Section 8.12 of the State Finance Act in any fiscal year do not reduce and do not constitute payment of any portion of the minimum State contribution required under this Article in that fiscal year. Such amounts shall not reduce, and shall not be included in the calculation of, the required State contributions under this Article in any future year until the System has reached a funding ratio of at least 90%. A reference in this Article to the "required State contribution" or any substantially similar term does not include or apply to any amounts payable to the System under Section 25 of the Budget Stabilization Act.
    Notwithstanding any other provision of this Section, the required State contribution for State fiscal year 2005 and for fiscal year 2008 and each fiscal year thereafter, as calculated under this Section and certified under Section 15-165, shall not exceed an amount equal to (i) the amount of the required State contribution that would have been calculated under this Section for that fiscal year if the System had not received any payments under subsection (d) of Section 7.2 of the General Obligation Bond Act, minus (ii) the portion of the State's total debt service payments for that fiscal year on the bonds issued in fiscal year 2003 for the purposes of that Section 7.2, as determined and certified by the Comptroller, that is the same as the System's portion of the total moneys distributed under subsection (d) of Section 7.2 of the General Obligation Bond Act. In determining this maximum for State fiscal years 2008 through 2010, however, the amount referred to in item (i) shall be increased, as a percentage of the applicable employee payroll, in equal increments calculated from the sum of the required State contribution for State fiscal year 2007 plus the applicable portion of the State's total debt service payments for fiscal year 2007 on the bonds issued in fiscal year 2003 for the purposes of Section 7.2 of the General Obligation Bond Act, so that, by State fiscal year 2011, the State is contributing at the rate otherwise required under this Section.
    (a-2) Beginning in fiscal year 2018, each employer under this Article shall pay to the System a required contribution determined as a percentage of projected payroll and sufficient to produce an annual amount equal to:
        (i) for each of fiscal years 2018, 2019, and 2020,
    
the defined benefit normal cost of the defined benefit plan, less the employee contribution, for each employee of that employer who has elected or who is deemed to have elected the benefits under Section 1-161 or who has made the election under subsection (c) of Section 1-161; for fiscal year 2021 and each fiscal year thereafter, the defined benefit normal cost of the defined benefit plan, less the employee contribution, plus 2%, for each employee of that employer who has elected or who is deemed to have elected the benefits under Section 1-161 or who has made the election under subsection (c) of Section 1-161; plus
        (ii) the amount required for that fiscal year to
    
amortize any unfunded actuarial accrued liability associated with the present value of liabilities attributable to the employer's account under Section 15-155.2, determined as a level percentage of payroll over a 30-year rolling amortization period.
    In determining contributions required under item (i) of this subsection, the System shall determine an aggregate rate for all employers, expressed as a percentage of projected payroll.
    In determining the contributions required under item (ii) of this subsection, the amount shall be computed by the System on the basis of the actuarial assumptions and tables used in the most recent actuarial valuation of the System that is available at the time of the computation.
    The contributions required under this subsection (a-2) shall be paid by an employer concurrently with that employer's payroll payment period. The State, as the actual employer of an employee, shall make the required contributions under this subsection.
    As used in this subsection, "academic year" means the 12-month period beginning September 1.
    (b) If an employee is paid from trust or federal funds, the employer shall pay to the Board contributions from those funds which are sufficient to cover the accruing normal costs on behalf of the employee. However, universities having employees who are compensated out of local auxiliary funds, income funds, or service enterprise funds are not required to pay such contributions on behalf of those employees. The local auxiliary funds, income funds, and service enterprise funds of universities shall not be considered trust funds for the purpose of this Article, but funds of alumni associations, foundations, and athletic associations which are affiliated with the universities included as employers under this Article and other employers which do not receive State appropriations are considered to be trust funds for the purpose of this Article.
    (b-1) The City of Urbana and the City of Champaign shall each make employer contributions to this System for their respective firefighter employees who participate in this System pursuant to subsection (h) of Section 15-107. The rate of contributions to be made by those municipalities shall be determined annually by the Board on the basis of the actuarial assumptions adopted by the Board and the recommendations of the actuary, and shall be expressed as a percentage of salary for each such employee. The Board shall certify the rate to the affected municipalities as soon as may be practical. The employer contributions required under this subsection shall be remitted by the municipality to the System at the same time and in the same manner as employee contributions.
    (c) Through State fiscal year 1995: The total employer contribution shall be apportioned among the various funds of the State and other employers, whether trust, federal, or other funds, in accordance with actuarial procedures approved by the Board. State of Illinois contributions for employers receiving State appropriations for personal services shall be payable from appropriations made to the employers or to the System. The contributions for Class I community colleges covering earnings other than those paid from trust and federal funds, shall be payable solely from appropriations to the Illinois Community College Board or the System for employer contributions.
    (d) Beginning in State fiscal year 1996, the required State contributions to the System shall be appropriated directly to the System and shall be payable through vouchers issued in accordance with subsection (c) of Section 15-165, except as provided in subsection (g).
    (e) The State Comptroller shall draw warrants payable to the System upon proper certification by the System or by the employer in accordance with the appropriation laws and this Code.
    (f) Normal costs under this Section means liability for pensions and other benefits which accrues to the System because of the credits earned for service rendered by the participants during the fiscal year and expenses of administering the System, but shall not include the principal of or any redemption premium or interest on any bonds issued by the Board or any expenses incurred or deposits required in connection therewith.
    (g) If the amount of a participant's earnings for any academic year used to determine the final rate of earnings, determined on a full-time equivalent basis, exceeds the amount of his or her earnings with the same employer for the previous academic year, determined on a full-time equivalent basis, by more than 6%, the participant's employer shall pay to the System, in addition to all other payments required under this Section and in accordance with guidelines established by the System, the present value of the increase in benefits resulting from the portion of the increase in earnings that is in excess of 6%. This present value shall be computed by the System on the basis of the actuarial assumptions and tables used in the most recent actuarial valuation of the System that is available at the time of the computation. The System may require the employer to provide any pertinent information or documentation.
    Whenever it determines that a payment is or may be required under this subsection (g), the System shall calculate the amount of the payment and bill the employer for that amount. The bill shall specify the calculations used to determine the amount due. If the employer disputes the amount of the bill, it may, within 30 days after receipt of the bill, apply to the System in writing for a recalculation. The application must specify in detail the grounds of the dispute and, if the employer asserts that the calculation is subject to subsection (h), (h-5), or (i) of this Section, must include an affidavit setting forth and attesting to all facts within the employer's knowledge that are pertinent to the applicability of that subsection. Upon receiving a timely application for recalculation, the System shall review the application and, if appropriate, recalculate the amount due.
    The employer contributions required under this subsection (g) may be paid in the form of a lump sum within 90 days after receipt of the bill. If the employer contributions are not paid within 90 days after receipt of the bill, then interest will be charged at a rate equal to the System's annual actuarially assumed rate of return on investment compounded annually from the 91st day after receipt of the bill. Payments must be concluded within 3 years after the employer's receipt of the bill.
    When assessing payment for any amount due under this subsection (g), the System shall include earnings, to the extent not established by a participant under Section 15-113.11 or 15-113.12, that would have been paid to the participant had the participant not taken (i) periods of voluntary or involuntary furlough occurring on or after July 1, 2015 and on or before June 30, 2017 or (ii) periods of voluntary pay reduction in lieu of furlough occurring on or after July 1, 2015 and on or before June 30, 2017. Determining earnings that would have been paid to a participant had the participant not taken periods of voluntary or involuntary furlough or periods of voluntary pay reduction shall be the responsibility of the employer, and shall be reported in a manner prescribed by the System.
    This subsection (g) does not apply to (1) Tier 2 hybrid plan members and (2) Tier 2 defined benefit members who first participate under this Article on or after the implementation date of the Optional Hybrid Plan.
    (g-1) (Blank).
    (h) This subsection (h) applies only to payments made or salary increases given on or after June 1, 2005 but before July 1, 2011. The changes made by Public Act 94-1057 shall not require the System to refund any payments received before July 31, 2006 (the effective date of Public Act 94-1057).
    When assessing payment for any amount due under subsection (g), the System shall exclude earnings increases paid to participants under contracts or collective bargaining agreements entered into, amended, or renewed before June 1, 2005.
    When assessing payment for any amount due under subsection (g), the System shall exclude earnings increases paid to a participant at a time when the participant is 10 or more years from retirement eligibility under Section 15-135.
    When assessing payment for any amount due under subsection (g), the System shall exclude earnings increases resulting from overload work, including a contract for summer teaching, or overtime when the employer has certified to the System, and the System has approved the certification, that: (i) in the case of overloads (A) the overload work is for the sole purpose of academic instruction in excess of the standard number of instruction hours for a full-time employee occurring during the academic year that the overload is paid and (B) the earnings increases are equal to or less than the rate of pay for academic instruction computed using the participant's current salary rate and work schedule; and (ii) in the case of overtime, the overtime was necessary for the educational mission.
    When assessing payment for any amount due under subsection (g), the System shall exclude any earnings increase resulting from (i) a promotion for which the employee moves from one classification to a higher classification under the State Universities Civil Service System, (ii) a promotion in academic rank for a tenured or tenure-track faculty position, or (iii) a promotion that the Illinois Community College Board has recommended in accordance with subsection (k) of this Section. These earnings increases shall be excluded only if the promotion is to a position that has existed and been filled by a member for no less than one complete academic year and the earnings increase as a result of the promotion is an increase that results in an amount no greater than the average salary paid for other similar positions.
    (h-5) When assessing payment for any amount due under subsection (g), the System shall exclude any earnings increase paid in an academic year beginning on or after July 1, 2020 resulting from overload work performed in an academic year subsequent to an academic year in which the employer was unable to offer or allow to be conducted overload work due to an emergency declaration limiting such activities.
    (i) When assessing payment for any amount due under subsection (g), the System shall exclude any salary increase described in subsection (h) of this Section given on or after July 1, 2011 but before July 1, 2014 under a contract or collective bargaining agreement entered into, amended, or renewed on or after June 1, 2005 but before July 1, 2011. Except as provided in subsection (h-5), any payments made or salary increases given after June 30, 2014 shall be used in assessing payment for any amount due under subsection (g) of this Section.
    (j) The System shall prepare a report and file copies of the report with the Governor and the General Assembly by January 1, 2007 that contains all of the following information:
        (1) The number of recalculations required by the
    
changes made to this Section by Public Act 94-1057 for each employer.
        (2) The dollar amount by which each employer's
    
contribution to the System was changed due to recalculations required by Public Act 94-1057.
        (3) The total amount the System received from each
    
employer as a result of the changes made to this Section by Public Act 94-4.
        (4) The increase in the required State contribution
    
resulting from the changes made to this Section by Public Act 94-1057.
    (j-5) For State fiscal years beginning on or after July 1, 2017, if the amount of a participant's earnings for any State fiscal year exceeds the amount of the salary set by law for the Governor that is in effect on July 1 of that fiscal year, the participant's employer shall pay to the System, in addition to all other payments required under this Section and in accordance with guidelines established by the System, an amount determined by the System to be equal to the employer normal cost, as established by the System and expressed as a total percentage of payroll, multiplied by the amount of earnings in excess of the amount of the salary set by law for the Governor. This amount shall be computed by the System on the basis of the actuarial assumptions and tables used in the most recent actuarial valuation of the System that is available at the time of the computation. The System may require the employer to provide any pertinent information or documentation.
    Whenever it determines that a payment is or may be required under this subsection, the System shall calculate the amount of the payment and bill the employer for that amount. The bill shall specify the calculation used to determine the amount due. If the employer disputes the amount of the bill, it may, within 30 days after receipt of the bill, apply to the System in writing for a recalculation. The application must specify in detail the grounds of the dispute. Upon receiving a timely application for recalculation, the System shall review the application and, if appropriate, recalculate the amount due.
    The employer contributions required under this subsection may be paid in the form of a lump sum within 90 days after issuance of the bill. If the employer contributions are not paid within 90 days after issuance of the bill, then interest will be charged at a rate equal to the System's annual actuarially assumed rate of return on investment compounded annually from the 91st day after issuance of the bill. All payments must be received within 3 years after issuance of the bill. If the employer fails to make complete payment, including applicable interest, within 3 years, then the System may, after giving notice to the employer, certify the delinquent amount to the State Comptroller, and the Comptroller shall thereupon deduct the certified delinquent amount from State funds payable to the employer and pay them instead to the System.
    This subsection (j-5) does not apply to a participant's earnings to the extent an employer pays the employer normal cost of such earnings.
    The changes made to this subsection (j-5) by Public Act 100-624 are intended to apply retroactively to July 6, 2017 (the effective date of Public Act 100-23).
    (k) The Illinois Community College Board shall adopt rules for recommending lists of promotional positions submitted to the Board by community colleges and for reviewing the promotional lists on an annual basis. When recommending promotional lists, the Board shall consider the similarity of the positions submitted to those positions recognized for State universities by the State Universities Civil Service System. The Illinois Community College Board shall file a copy of its findings with the System. The System shall consider the findings of the Illinois Community College Board when making determinations under this Section. The System shall not exclude any earnings increases resulting from a promotion when the promotion was not submitted by a community college. Nothing in this subsection (k) shall require any community college to submit any information to the Community College Board.
    (l) For purposes of determining the required State contribution to the System, the value of the System's assets shall be equal to the actuarial value of the System's assets, which shall be calculated as follows:
    As of June 30, 2008, the actuarial value of the System's assets shall be equal to the market value of the assets as of that date. In determining the actuarial value of the System's assets for fiscal years after June 30, 2008, any actuarial gains or losses from investment return incurred in a fiscal year shall be recognized in equal annual amounts over the 5-year period following that fiscal year.
    (m) For purposes of determining the required State contribution to the system for a particular year, the actuarial value of assets shall be assumed to earn a rate of return equal to the system's actuarially assumed rate of return.

    (a) Except as otherwise specified, if any employer fails to transmit to the System contributions required of it under this Article or contributions collected by it from its participating employees for the purposes of this Article for more than 120 days after the payment of those contributions is due, the Board, after giving notice to that employer, may certify to the State Comptroller the amounts of such delinquent payments in accordance with any applicable rules of the Comptroller, and the Comptroller shall deduct the amounts so certified or any part thereof from any payments of State funds to the employer involved and shall remit the amount so deducted to the System. If State funds from which such deductions may be made are not available or if deductions are delayed for longer than 120 days after the date of the certification to the Comptroller, the Board may proceed against the employer to recover the amounts of such delinquent payments in the appropriate circuit court.
    (b) Except as otherwise specified, if any employer that is a community college district fails to transmit to the System contributions required of it under this Article or contributions collected by it from its participating employees for the purposes of this Article for more than 120 days after the payment of those contributions is due, the Board, after giving notice to that employer, may certify the fact of such delinquent payment to the county treasurer of the county in which that employer is located, who shall thereafter remit the amounts collected from any taxes levied by the employer directly to the System. If the funds from which such remittances may be made are not available or if the remittances are delayed for longer than 120 days after the date of the certification to the county treasurer, the Board may proceed against the employer to recover the amounts of such delinquent payments in the appropriate circuit court.
    (c) Nothing in this Section prohibits the Board from proceeding against an employer to recover the amounts of any delinquent payments in the appropriate circuit court.

    Sec. 15-156. Obligations of State; funding guarantees.
    (a) The payment of (1) the required State contributions, (2) all benefits granted under this system and (3) all expenses in connection with the administration and operation thereof are obligations of the State of Illinois to the extent specified in this Article. The accumulated employee normal, additional and survivors insurance contributions credited to the accounts of active and inactive participants shall not be used to pay the State's share of the obligations.
    (b) Beginning July 1, 2014, the State shall be obligated to contribute to the System in each State fiscal year an amount not less than the sum of (i) the State's normal cost for the year and (ii) the portion of the unfunded accrued liability assigned to that year by law. Notwithstanding any other provision of law, if the State fails to pay an amount required under this subsection, it shall be the obligation of the Board to seek payment of the required amount in compliance with the provisions of this Section and, if the amount remains unpaid, to bring a mandamus action in the Supreme Court of Illinois to compel the State to make the required payment.
    If the System submits a voucher for contributions required under Section 15-155 and the State fails to pay that voucher within 90 days of its receipt, the Board shall submit a written request to the Comptroller seeking payment.

    This subsection (b) constitutes an express waiver of the State's sovereign immunity solely to the extent that it permits the Board to commence a mandamus action in the Supreme Court of Illinois to compel the Comptroller to pay a voucher for the contributions required under Section 15-155.
    (c) Beginning in State fiscal year 2016, the State shall be obligated to make the transfers set forth in subsections (c-5) and (c-10) of Section 20 of the Budget Stabilization Act and to pay to the System its proportionate share of the transferred amounts in accordance with Section 25 of the Budget Stabilization Act.

A copy of the request shall be filed with the Secretary of State, and the Secretary of State shall provide a copy to the Governor and General Assembly. No earlier than the 16th day after the System files the request with the Comptroller and Secretary of State, if the required amount remains untransferred or the required payment remains unpaid, the Board shall commence a mandamus action in the Supreme Court of Illinois to compel the Comptroller to make the required transfer or payment or both, as the case may be.
    This subsection (c) constitutes an express waiver of the State's sovereign immunity solely to the extent that it permits the Board to commence a mandamus action in the Supreme Court of Illinois to compel the Comptroller to make a transfer required under subsection (c-5) or (c-10) of Section 20 of the Budget Stabilization Act and to pay to the System its proportionate share of the transferred amount in accordance with Section 25 of the Budget Stabilization Act.
    The obligations created by this subsection (c) expire when all of the requirements of subsections (c-5) and (c-10) of Section 20 of the Budget Stabilization Act and Section 25 of the Budget Stabilization Act have been met.
    (d) Any payments and transfers required to be made by the State pursuant to subsection (b) or (c) are expressly subordinate to the payment of the principal, interest, and premium, if any, on any bonded debt obligation of the State or any other State-created entity, either currently outstanding or to be issued, for which the source of repayment or security thereon is derived directly or indirectly from tax revenues collected by the State or any other State-created entity. Payments on such bonded obligations include any statutory fund transfers or other prefunding mechanisms or formulas set forth, now or hereafter, in State law or bond indentures, into debt service funds or accounts of the State related to such bond obligations, consistent with the payment schedules associated with such obligations.

    (40 ILCS 5/15-157) (from Ch. 108 1/2, par. 15-157)
    Sec. 15-157. Employee Contributions.
    (a) Each participating employee shall make contributions towards the retirement benefits payable under the retirement program applicable to the employee from each payment of earnings applicable to employment under this system on and after the date of becoming a participant as follows: Prior to September 1, 1949, 3 1/2% of earnings; from September 1, 1949 to August 31, 1955, 5%; from September 1, 1955 to August 31, 1969, 6%; from September 1, 1969, 6 1/2%. These contributions are to be considered as normal contributions for purposes of this Article.
    Each participant who is a police officer or firefighter shall make normal contributions of 8% of each payment of earnings applicable to employment as a police officer or firefighter under this system on or after September 1, 1981, unless he or she files with the board within 60 days after the effective date of this amendatory Act of 1991 or 60 days after the board receives notice that he or she is employed as a police officer or firefighter, whichever is later, a written notice waiving the retirement formula provided by Rule 4 of Section 15-136. This waiver shall be irrevocable. If a participant had met the conditions set forth in Section 15-132.1 prior to the effective date of this amendatory Act of 1991 but failed to make the additional normal contributions required by this paragraph, he or she may elect to pay the additional contributions plus compound interest at the effective rate. If such payment is received by the board, the service shall be considered as police officer service in calculating the retirement annuity under Rule 4 of Section 15-136. While performing service described in clause (i) or (ii) of Rule 4 of Section 15-136, a participating employee shall be deemed to be employed as a firefighter for the purpose of determining the rate of employee contributions under this Section.
    (b) Starting September 1, 1969, each participating employee shall make additional contributions of 1/2 of 1% of earnings to finance a portion of the cost of the annual increases in retirement annuity provided under Section 15-136, except that with respect to participants in the self-managed plan this additional contribution shall be used to finance the benefits obtained under that retirement program.
    (c) In addition to the amounts described in subsections (a) and (b) of this Section, each participating employee shall make contributions of 1% of earnings applicable under this system on and after August 1, 1959. The contributions made under this subsection (c) shall be considered as survivor's insurance contributions for purposes of this Article if the employee is covered under the traditional benefit package, and such contributions shall be considered as additional contributions for purposes of this Article if the employee is participating in the self-managed plan or has elected to participate in the portable benefit package and has completed the applicable one-year waiting period. Contributions in excess of $80 during any fiscal year beginning before August 31, 1969 and in excess of $120 during any fiscal year thereafter until September 1, 1971 shall be considered as additional contributions for purposes of this Article.
    (d) If the board by board rule so permits and subject to such conditions and limitations as may be specified in its rules, a participant may make other additional contributions of such percentage of earnings or amounts as the participant shall elect in a written notice thereof received by the board.
    (e) That fraction of a participant's total accumulated normal contributions, the numerator of which is equal to the number of years of service in excess of that which is required to qualify for the maximum retirement annuity, and the denominator of which is equal to the total service of the participant, shall be considered as accumulated additional contributions. The determination of the applicable maximum annuity and the adjustment in contributions required by this provision shall be made as of the date of the participant's retirement.
    (f) Notwithstanding the foregoing, a participating employee shall not be required to make contributions under this Section after the date upon which continuance of such contributions would otherwise cause his or her retirement annuity to exceed the maximum retirement annuity as specified in clause (1) of subsection (c) of Section 15-136.
    (g) A participant may make contributions for the purchase of service credit under this Article; however, only a participating employee may make optional contributions under subsection (b) of Section 15-157.1 of this Article.
    (h) A Tier 2 member shall not make contributions on earnings that exceed the limitation as prescribed under subsection (b) of Section 15-111 of this Article.

    Sec. 15-157.1. Pickup of employee contributions.
    (a) Each employer shall pick up the employee contributions required under subsections (a), (b), and (c) of Section 15-157 for all earnings payments made on and after January 1, 1981, and the contributions so picked up shall be treated as employer contributions in determining tax treatment under the United States Internal Revenue Code. These contributions shall not be included as gross income of the participant until such time as they are distributed or made available. The employer shall pay these employee contributions from the same source of funds which is used in paying earnings to the employee. The employer may pick up these contributions by a reduction in the cash salary of the participants, or by an offset against a future salary increase, or by a combination of a reduction in salary and offset against a future salary increase.
    (b) Subject to the requirements of federal law, a participating employee may elect to have the employer pick up optional contributions that the participant has elected to pay to the System under Section 15-157(g), and the contributions so picked up shall be treated as employer contributions for the purposes of determining federal tax treatment under the federal Internal Revenue Code of 1986. These contributions shall not be included as gross income of the participant until such time as they are distributed or made available. The employer shall pick up the contributions by a reduction in the cash salary of the participant and shall pay the contributions from the same source of funds that is used to pay earnings to the participant. The election to have optional contributions picked up is irrevocable.

40 ILCS 5/15-158.2

    (40 ILCS 5/15-158.2)
    Sec. 15-158.2. Self-managed plan.
    (a) Purpose. The General Assembly finds that it is important for colleges and universities to be able to attract and retain the most qualified employees and that in order to attract and retain these employees, colleges and universities should have the flexibility to provide a defined contribution plan as an alternative for eligible employees who elect not to participate in a defined benefit retirement program provided under this Article. Accordingly, the State Universities Retirement System is hereby authorized to establish and administer a self-managed plan, which shall offer participating employees the opportunity to accumulate assets for retirement through a combination of employee and employer contributions that may be invested in mutual funds, collective investment funds, or other investment products and used to purchase annuity contracts, either fixed or variable or a combination thereof. The plan must be qualified under the Internal Revenue Code of 1986.
    (b) Adoption by employers. Each employer subject to this Article may elect to adopt the self-managed plan established under this Section; this election is irrevocable. An employer's election to adopt the self-managed plan makes available to the eligible employees of that employer the elections described in Section 15-134.5.
    The State Universities Retirement System shall be the plan sponsor for the self-managed plan and shall prepare a plan document and prescribe such rules and procedures as are considered necessary or desirable for the administration of the self-managed plan. Consistent with its fiduciary duty to the participants and beneficiaries of the self-managed plan, the Board of Trustees of the System may delegate aspects of plan administration as it sees fit to companies authorized to do business in this State, to the employers, or to a combination of both.
    (c) Selection of service providers and funding vehicles. The System, in consultation with the employers, shall solicit proposals to provide administrative services and funding vehicles for the self-managed plan from insurance and annuity companies and mutual fund companies, banks, trust companies, or other financial institutions authorized to do business in this State. In reviewing the proposals received and approving and contracting with no fewer than 2 and no more than 7 companies, the Board of Trustees of the System shall consider, among other things, the following criteria:
        (1) the nature and extent of the benefits that would
    
be provided to the participants;
        (2) the reasonableness of the benefits in relation to
    
the premium charged;
        (3) the suitability of the benefits to the needs and
    
interests of the participating employees and the employer;
        (4) the ability of the company to provide benefits
    
under the contract and the financial stability of the company; and
        (5) the efficacy of the contract in the recruitment
    
and retention of employees.
    The System, in consultation with the employers, shall periodically review each approved company. A company may continue to provide administrative services and funding vehicles for the self-managed plan only so long as it continues to be an approved company under contract with the Board.
    (d) Employee Direction. Employees who are participating in the program must be allowed to direct the transfer of their account balances among the various investment options offered, subject to applicable contractual provisions. The participant shall not be deemed a fiduciary by reason of providing such investment direction. A person who is a fiduciary shall not be liable for any loss resulting from such investment direction and shall not be deemed to have breached any fiduciary duty by acting in accordance with that direction. The System shall provide advance notice to the participant of the participant's obligation to direct the investment of employee and employer contributions into one or more investment funds selected by the System at the time he or she makes his or her initial retirement plan selection. If a participant fails to direct the investment of employee and employer contributions into the various investment options offered to the participant when making his or her initial retirement election choice, that failure shall require the System to invest the employee and employer contributions in a default investment fund on behalf of the participant, and the investment shall be deemed to have been made at the participant's investment direction. The participant has the right to transfer account balances out of the default investment fund during time periods designated by the System. Neither the System nor the employer guarantees any of the investments in the employee's account balances.
    (e) Participation. An employee eligible to participate in the self-managed plan must make a written election in accordance with the provisions of Section 15-134.5 and the procedures established by the System. Participation in the self-managed plan by an electing employee shall begin on the first day of the first pay period following the later of the date the employee's election is filed with the System or the effective date as of which the employee's employer begins to offer participation in the self-managed plan. Employers may not make the self-managed plan available earlier than January 1, 1998. An employee's participation in any other retirement program administered by the System under this Article shall terminate on the date that participation in the self-managed plan begins.
    An employee who has elected to participate in the self-managed plan under this Section must continue participation while employed in an eligible position, and may not participate in any other retirement program administered by the System under this Article while employed by that employer or any other employer that has adopted the self-managed plan, unless the self-managed plan is terminated in accordance with subsection (i).
    Notwithstanding any other provision of this Article, a Tier 2 member shall have the option to enroll in the self-managed plan.
    Participation in the self-managed plan under this Section shall constitute membership in the State Universities Retirement System.
    A participant under this Section shall be entitled to the benefits of Article 20 of this Code.
    (f) Establishment of Initial Account Balance. If at the time an employee elects to participate in the self-managed plan he or she has rights and credits in the System due to previous participation in the traditional benefit package, the System shall establish for the employee an opening account balance in the self-managed plan, equal to the amount of contribution refund that the employee would be eligible to receive under Section 15-154 if the employee terminated employment on that date and elected a refund of contributions, except that this hypothetical refund shall include interest at the effective rate for the respective years. The System shall transfer assets from the defined benefit retirement program to the self-managed plan, as a tax free transfer in accordance with Internal Revenue Service guidelines, for purposes of funding the employee's opening account balance.
    (g) No Duplication of Service Credit. Notwithstanding any other provision of this Article, an employee may not purchase or receive service or service credit applicable to any other retirement program administered by the System under this Article for any period during which the employee was a participant in the self-managed plan established under this Section.
    (h) Contributions. The self-managed plan shall be funded by contributions from employees participating in the self-managed plan and employer contributions as provided in this Section.
    The contribution rate for employees participating in the self-managed plan under this Section shall be equal to the employee contribution rate for other participants in the System, as provided in Section 15-157. This required contribution shall be made as an "employer pick-up" under Section 414(h) of the Internal Revenue Code of 1986 or any successor Section thereof. Any employee participating in the System's traditional benefit package prior to his or her election to participate in the self-managed plan shall continue to have the employer pick up the contributions required under Section 15-157. However, the amounts picked up after the election of the self-managed plan shall be remitted to and treated as assets of the self-managed plan. In no event shall an employee have an option of receiving these amounts in cash. Employees may make additional contributions to the self-managed plan in accordance with procedures prescribed by the System, to the extent permitted under rules prescribed by the System.
    The program shall provide for employer contributions to be credited to each self-managed plan participant at a rate of 7.6% of the participating employee's salary, less the amount used by the System to provide disability benefits for the employee. The amounts so credited shall be paid into the participant's self-managed plan accounts in a manner to be prescribed by the System.
    An amount of employer contribution, not exceeding 1% of the participating employee's salary, shall be used for the purpose of providing the disability benefits of the System to the employee. Prior to the beginning of each plan year under the self-managed plan, the Board of Trustees shall determine, as a percentage of salary, the amount of employer contributions to be allocated during that plan year for providing disability benefits for employees in the self-managed plan.
    The State of Illinois shall make contributions by appropriations to the System of the employer contributions required for employees who participate in the self-managed plan under this Section. The amount required shall be certified by the Board of Trustees of the System and paid by the State in accordance with Section 15-165. The System shall not be obligated to remit the required employer contributions to any of the insurance and annuity companies, mutual fund companies, banks, trust companies, financial institutions, or other sponsors of any of the funding vehicles offered under the self-managed plan until it has received the required employer contributions from the State. In the event of a deficiency in the amount of State contributions, the System shall implement those procedures described in subsection (c) of Section 15-165 to obtain the required funding from the General Revenue Fund.
    (i) Termination. The self-managed plan authorized under this Section may be terminated by the System, subject to the terms of any relevant contracts, and the System shall have no obligation to reestablish the self-managed plan under this Section. This Section does not create a right to continued participation in any self-managed plan set up by the System under this Section. If the self-managed plan is terminated, the participants shall have the right to participate in one of the other retirement programs offered by the System and receive service credit in such other retirement program for any years of employment following the termination.
    (j) Vesting; Withdrawal; Return to Service. A participant in the self-managed plan becomes vested in the employer contributions credited to his or her accounts in the self-managed plan on the earliest to occur of the following: (1) completion of 5 years of service with an employer described in Section 15-106; (2) the death of the participating employee while employed by an employer described in Section 15-106, if the participant has completed at least 1 1/2 years of service; or (3) the participant's election to retire and apply the reciprocal provisions of Article 20 of this Code.
    A participant in the self-managed plan who receives a distribution of his or her vested amounts from the self-managed plan while not yet eligible for retirement under this Article (and Article 20, if applicable) shall forfeit all service credit and accrued rights in the System; if subsequently re-employed, the participant shall be considered a new employee. If a former participant again becomes a participating employee (or becomes employed by a participating system under Article 20 of this Code) and continues as such for at least 2 years, all such rights, service credits, and previous status as a participant shall be restored upon repayment of the amount of the distribution, without interest.
    (k) Benefit amounts. If an employee who is vested in employer contributions terminates employment, the employee shall be entitled to a benefit which is based on the account values attributable to both employer and employee contributions and any investment return thereon.
    If an employee who is not vested in employer contributions terminates employment, the employee shall be entitled to a benefit based solely on the account values attributable to the employee's contributions and any investment return thereon, and the employer contributions and any investment return thereon shall be forfeited. Any employer contributions which are forfeited shall be held in escrow by the company investing those contributions and shall be used as directed by the System for future allocations of employer contributions or for the restoration of amounts previously forfeited by former participants who again become participating employees.

    On or before July 1, 2005, the Board shall recalculate and recertify to the Governor the amount of the required State contribution to the System for State fiscal year 2006, taking into account the changes in required State contributions made by this amendatory Act of the 94th General Assembly.
    On or before April 1, 2011, the Board shall recalculate and recertify to the Governor the amount of the required State contribution to the System for State fiscal year 2011, applying the changes made by Public Act 96-889 to the System's assets and liabilities as of June 30, 2009 as though Public Act 96-889 was approved on that date.
    (a-5) On or before November 1 of each year, beginning November 1, 2012, the Board shall submit to the State Actuary, the Governor, and the General Assembly a proposed certification of the amount of the required State contribution to the System for the next fiscal year, along with all of the actuarial assumptions, calculations, and data upon which that proposed certification is based. On or before January 1 of each year, beginning January 1, 2013, the State Actuary shall issue a preliminary report concerning the proposed certification and identifying, if necessary, recommended changes in actuarial assumptions that the Board must consider before finalizing its certification of the required State contributions.

The monthly voucher for the 12th month of fiscal year 2019 shall be paid by the Comptroller after the recertification required pursuant to this subsection is submitted to the Governor, Comptroller, and General Assembly. The recertification submitted to the General Assembly shall be filed with the Clerk of the House of Representatives and the Secretary of the Senate in electronic form only, in the manner that the Clerk and the Secretary shall direct.
    (b) The Board shall certify to the State Comptroller or employer, as the case may be, from time to time, by its chairperson and secretary, with its seal attached, the amounts payable to the System from the various funds.
    (c) Beginning in State fiscal year 1996, on or as soon as possible after the 15th day of each month the Board shall submit vouchers for payment of State contributions to the System, in a total monthly amount of one-twelfth of the required annual State contribution certified under subsection (a). From the effective date of this amendatory Act of the 93rd General Assembly through June 30, 2004, the Board shall not submit vouchers for the remainder of fiscal year 2004 in excess of the fiscal year 2004 certified contribution amount determined under this Section after taking into consideration the transfer to the System under subsection (b) of Section 6z-61 of the State Finance Act. These vouchers shall be paid by the State Comptroller and Treasurer by warrants drawn on the funds appropriated to the System for that fiscal year.
    If in any month the amount remaining unexpended from all other appropriations to the System for the applicable fiscal year (including the appropriations to the System under Section 8.12 of the State Finance Act and Section 1 of the State Pension Funds Continuing Appropriation Act) is less than the amount lawfully vouchered under this Section, the difference shall be paid from the General Revenue Fund under the continuing appropriation authority provided in Section 1.1 of the State Pension Funds Continuing Appropriation Act.
    (d) So long as the payments received are the full amount lawfully vouchered under this Section, payments received by the System under this Section shall be applied first toward the employer contribution to the self-managed plan established under Section 15-158.2. Payments shall be applied second toward the employer's portion of the normal costs of the System, as defined in subsection (f) of Section 15-155. The balance shall be applied toward the unfunded actuarial liabilities of the System.
    (e) In the event that the System does not receive, as a result of legislative enactment or otherwise, payments sufficient to fully fund the employer contribution to the self-managed plan established under Section 15-158.2 and to fully fund that portion of the employer's portion of the normal costs of the System, as calculated in accordance with Section 15-155(a-1), then any payments received shall be applied proportionately to the optional retirement program established under Section 15-158.2 and to the employer's portion of the normal costs of the System, as calculated in accordance with Section 15-155(a-1).
