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 5/15-139.5

    (40 ILCS 5/15-139.5)
    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.

40 ILCS 5/15-140

    (40 ILCS 5/15-140) (from Ch. 108 1/2, par. 15-140)
    Sec. 15-140. Reversionary annuities. A participant in the traditional benefit package entitled to a retirement annuity may, prior to retirement, elect to take a reduced retirement annuity and provide with the actuarial value of the reduction, a reversionary annuity to a dependent beneficiary, subject to the following conditions: (1) the participant's written notice of election to provide such annuity is received by the board at least 30 days before the retirement annuity payment period begins, and (2) the amount of the reversionary annuity is not less than $10 per month, and (3) the reversionary annuity is payable only if the participant dies after retirement.
    The participant may revoke the election by filing a written notice of revocation with the board. The beneficiary's death prior to retirement of the participant shall constitute a revocation of the election.
    The amount of the reversionary annuity shall be that specified in the participant's notice of election, but not more than the amount which when added to the survivors annuity payable to the dependent beneficiary, would equal the participant's reduced retirement annuity. The participant shall specify in the notice of election whether the full retirement annuity is to be resumed or the reduced retirement annuity is to be continued, in the event the beneficiary predeceases the annuitant.
    The reversionary annuity payment period shall begin on the day following the annuitant's death. A reversionary annuity shall not be payable if the beneficiary predeceases the annuitant.

    (40 ILCS 5/15-141) (from Ch. 108 1/2, par. 15-141)
    Sec. 15-141. Death benefits - Death of participant.
    (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.

40 ILCS 5/15-142

    (40 ILCS 5/15-142) (from Ch. 108 1/2, par. 15-142)
    Sec. 15-142. Death benefits - Death of annuitant. Upon the death of an annuitant receiving a retirement annuity or disability retirement annuity, the annuitant's beneficiary shall, if a survivor's insurance benefit is not payable under Section 15-145 and an annuity is not payable under Section 15-136.4, be entitled to a death benefit equal to the greater of the following: (1) the excess, if any, of the sum of the accumulated normal, survivors insurance, and additional contributions as of the date of retirement or the date the disability retirement annuity began, whichever is earlier, over the sum of all annuity payments made prior to the date of death, or (2) $1,000.

    Sec. 15-143. Death benefits - general provisions. All death benefits shall be paid as a single cash sum.

40 ILCS 5/15-144

    (40 ILCS 5/15-144) (from Ch. 108 1/2, par. 15-144)
    Sec. 15-144. Beneficiary annuities. This Section applies only to the death benefits of persons who became participants before August 22, 1997 (the effective date of Public Act 90-511).
    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.

40 ILCS 5/15-145

    (40 ILCS 5/15-145) (from Ch. 108 1/2, par. 15-145)
    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.

40 ILCS 5/15-145.1

    (40 ILCS 5/15-145.1)
    Sec. 15-145.1. Survivor's insurance annuities and lump sum payments for Tier 2 Members; amount. 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.

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

    Sec. 15-146.1. Survivors insurance benefits-Maximum amounts.
    (a) The maximum total survivors annuity payable on account of any deceased participating employee shall be the lesser of: (1) 80% of the final rate of earnings; or (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.
    (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.
    (i) This Section applies to the survivors insurance benefits provided to the eligible survivors of a Tier 1 member.

    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.

    (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.

    Sec. 15-154.1. Maximum benefits. The combined retirement annuity, survivors insurance, death benefits, or disability benefits under this system and any other system which is, has been, or may be financed fully or in part by contributions from any alumni association, foundation or athletic association affiliated with the universities included as employers, shall not exceed the largest benefit which could be payable by this system or such other system based upon the participant's combined service and earnings credits.
    If the combined benefits exceed the largest benefit as determined in accordance with this Section, the benefits payable by this system shall be reduced to that amount which, when added to the benefits payable under such other system, equals this largest benefit.
    If benefits are reduced, this system shall pay to the alumni association, foundation or athletic association which financed such other system, that fraction of the reduction, the numerator of which is the amount of the benefits payable by the other system prior to the adjustment and the denominator of which is the amount of the combined benefits which would have been payable prior to the adjustment. In determining the adjustment of the survivors insurance or death benefit made under this Section, the benefits payable under this system and the other systems shall be reduced to common actuarial equivalents in accordance with the mortality, interest, and annuity tables adopted by the board and the method of payment required by this Article.

    (40 ILCS 5/15-155) (from Ch. 108 1/2, par. 15-155)
    Sec. 15-155. Employer contributions.
    (a) The State of Illinois shall make contributions by appropriations of amounts which, together with the other employer contributions from trust, federal, and other funds, employee contributions, income from investments, and other income of this System, will be sufficient to meet the cost of maintaining and administering the System on a 90% funded basis in accordance with actuarial recommendations.
    The Board shall determine the amount of State contributions required for each fiscal year on the basis of the actuarial tables and other assumptions adopted by the Board and the recommendations of the actuary, using the formula in subsection (a-1).
    (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.

    (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.

    (Text of Section WITH the changes made by P.A. 98-599, which has been held unconstitutional)
    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. 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 amount remains unpaid the Board shall commence a mandamus action in the Supreme Court of Illinois to compel the Comptroller to satisfy the voucher.
    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. Notwithstanding any other provision of law, if the State fails to transfer an amount required under this subsection or to pay to the System its proportionate share of the transferred amount in accordance with Section 25 of the Budget Stabilization Act, it shall be the obligation of the Board to seek transfer or payment of the required amount in compliance with the provisions of this Section and, if the required amount remains untransferred or the required payment remains unpaid, to bring a mandamus action in the Supreme Court of Illinois to compel the State to make the required transfer or payment or both, as the case may be.
    If the State fails to make a transfer required under subsection (c-5) or (c-10) of Section 20 of the Budget Stabilization Act or a payment to the System required under Section 25 of that Act, the Board shall submit a written request to the Comptroller seeking payment. 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.

    (a) The Board shall certify to the Governor on or before November 15 of each year until November 15, 2011 the appropriation required from State funds for the purposes of this System for the following fiscal year. The certification under this subsection (a) shall include a copy of the actuarial recommendations upon which it is based and shall specifically identify the System's projected State normal cost for that fiscal year and the projected State cost for the self-managed plan for that fiscal year.
    On or before May 1, 2004, the Board shall recalculate and recertify to the Governor the amount of the required State contribution to the System for State fiscal year 2005, taking into account the amounts appropriated to and received by the System under subsection (d) of Section 7.2 of the General Obligation Bond Act.
    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. On or before January 15, 2013 and each January 15 thereafter, the Board shall certify to the Governor and the General Assembly the amount of the required State contribution for the next fiscal year. The Board's certification must note, in a written response to the State Actuary, any deviations from the State Actuary's recommended changes, the reason or reasons for not following the State Actuary's recommended changes, and the fiscal impact of not following the State Actuary's recommended changes on the required State contribution.
    (a-10) By November 1, 2017, the Board shall recalculate and recertify to the State Actuary, the Governor, and the General Assembly the amount of the State contribution to the System for State fiscal year 2018, taking into account the changes in required State contributions made by this amendatory Act of the 100th General Assembly. The State Actuary shall review the assumptions and valuations underlying the Board's revised certification and issue a preliminary report concerning the proposed recertification and identifying, if necessary, recommended changes in actuarial assumptions that the Board must consider before finalizing its certification of the required State contributions. The Board's final certification must note any deviations from the State Actuary's recommended changes, the reason or reasons for not following the State Actuary's recommended changes, and the fiscal impact of not following the State Actuary's recommended changes on the required State contribution.
    (a-15) On or after June 15, 2019, but no later than June 30, 2019, the Board shall recalculate and recertify to the Governor and the General Assembly the amount of the State contribution to the System for State fiscal year 2019, taking into account the changes in required State contributions made by this amendatory Act of the 100th General Assembly. The recalculation shall be made using assumptions adopted by the Board for the original fiscal year 2019 certification. 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).

        (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;
        (4) has not made the election under Section 15-185.6;
    
and
        (5) is not a participant in the self-managed plan
    
under Section 15-158.2.
    "Implementation date" means the earliest date upon which the Board authorizes eligible persons to begin irrevocably electing the accelerated pension benefit payment option under this Section. The Board shall endeavor to make such participation available as soon as possible after June 4, 2018 (the effective date of Public Act 100-587) and shall establish an implementation date by Board resolution.
    "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 survivors benefits, disability benefits, or disability retirement annuity benefits.
    (b) Beginning on the implementation date, the System 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 System shall calculate, using actuarial tables and other assumptions adopted by the Board, the present value of pension benefits for each eligible person upon his or her request in writing to the System. The System shall not perform more than one calculation per eligible member in a State fiscal year. 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. The System shall make a good faith effort to contact every eligible person to notify him or her of the election.
    Beginning on the implementation date and 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) Upon payment of an accelerated pension benefit payment under this Section, the person forfeits all accrued rights and credits in the System and no other benefit shall be paid under this Article based on those forfeited rights and credits, 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 participation under this Article, any benefits under the System earned as a result of that return to participation shall be based solely on the person's credits and creditable service arising from the return to participation. Upon return to participation, the person shall be considered a new employee subject to all the qualifying conditions for participation and eligibility for benefits applicable to new employees.
    (d-5) The accelerated pension benefit payment may not be repaid to the System, and the forfeited rights and credits 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 deposited into a tax qualified retirement plan or account identified by the eligible person at the time of the election. 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) The System shall submit vouchers to the State Comptroller for the payment of accelerated pension benefit payments under this Section. The State Comptroller shall pay the amounts of the vouchers from the State Pension Obligation Acceleration Bond Fund to the System, and the System shall deposit the amounts into the applicable tax qualified plans or accounts.
    (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 System to cease to be a qualified plan under the Internal Revenue Code of 1986.

    (b) Beginning on the implementation date and until June 30, 2026, the System shall implement an accelerated pension benefit payment option for eligible persons. The System shall calculate, using actuarial tables and other assumptions adopted by the Board, an accelerated pension benefit payment amount for an eligible person upon his or her request in writing to the System and shall offer that eligible person the opportunity to irrevocably elect to have his or her automatic annual increases in retirement annuity and any annuity benefit payable as a result of his or her death calculated in accordance with the formula provided in subsection (b-5) in exchange for the accelerated pension benefit payment. The System shall not perform more than one calculation under this Section per eligible person in a State fiscal year. The election under this subsection must be made before any retirement annuity is paid to the eligible person, and the eligible survivor, spouse, or contingent annuitant, as applicable, must consent to the election under this subsection.
    (b-5) Notwithstanding any other provision of law, the retirement annuity of a person who made the election under subsection (b) shall be increased annually beginning 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, and any annuity benefit payable as a result of his or her death shall be increased annually beginning on: (1) the January 1 occurring on or after the commencement of the annuity if the deceased Tier 1 member died while receiving a retirement annuity; or (2) the January 1 occurring after the first anniversary of the commencement of the benefit. Each annual increase shall be calculated at 1.5% of the originally granted retirement annuity or annuity benefit payable as a result of the Tier 1 member's death.
    (c) If an annuitant who has received an accelerated pension benefit payment returns to participation under this Article, the calculation of any future automatic annual increase in retirement annuity under subsection (c) of Section 15-139 shall be calculated in accordance with the formula provided in subsection (b-5).
    (c-5) 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 deposited into a tax qualified retirement plan or account identified by the eligible person at the time of election.

    (d-5) The System shall submit vouchers to the State Comptroller for the payment of accelerated pension benefit payments under this Section. The State Comptroller shall pay the amounts of the vouchers from the State Pension Obligation Acceleration Bond Fund to the System, and the System shall deposit the amounts into the applicable tax qualified plans or accounts.
    (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 System to cease to be a qualified plan under the Internal Revenue Code of 1986.

    Sec. 15-186.1. Mistake in benefit calculation and overpayment recovery.
    (a) Mistake in benefit calculation. 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, plus interest at the effective rate from the date the unpaid amounts accrued to the date of payment.
    If the benefit was mistakenly set too high, the System may recover the amount overpaid from the recipient thereof, plus interest at the effective rate from the date of overpayment to the date of recovery, 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 or information omitted 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.
    (b) Overpayment recovery. Regardless of the date an overpayment is discovered, if the System determines that the overpayment has occurred for any reason other than those specified in subsection (a) of this Section, the System may recover the overpayment from the recipient thereof or the recipient's estate, plus interest at the effective rate from the date of the overpayment to the date of recovery, either directly or by deducting such amount from the remaining benefits payable to the recipient or the recipient's estate, or by any other means available to the System. This subsection (b) applies to overpayments occurring before, on, or after the effective date of 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.

    (40 ILCS 5/15-202)
    Sec. 15-202. Optional deferred compensation plan.
    (a) As soon as practicable after August 10, 2018 (the effective date of Public Act 100-769), the System shall offer a deferred compensation plan that is eligible under Section 457(b) of the Internal Revenue Code of 1986, as amended, to participating employees of the System employed by employers described in Section 15-106 of this Code that qualify as eligible employers under Section 457(e)(1)(A) of the Internal Revenue Code of 1986, as amended. Such eligible employers shall adopt the plan with an effective date no later than September 1, 2021. Participating employees may voluntarily elect to make elective deferrals to the eligible deferred compensation plan. Eligible employers may make optional employer contributions to the plan on behalf of participating employees, which contributions may be maintained, increased, reduced, or eliminated at the discretion of the employer from plan year to plan year. The plan shall collect voluntary employee and optional employer contributions into an account for each participant and shall offer investment options to the participant. The plan under this Section shall be operated in full compliance with any applicable State and federal laws, and the System shall utilize generally accepted practices in creating and maintaining the plan for the best interest of the participants. In administering the deferred compensation plan, the System shall require that the deferred compensation plan recordkeeper agree that, in performing services with respect to the deferred compensation plan, the recordkeeper: (i) will not use information received as a result of providing services with respect to the deferred compensation plan or the participants in the deferred compensation plan to solicit the participants in the deferred compensation plan for the purpose of cross-selling nonplan products and services, unless in response to a request by a participant in the deferred compensation plan; and (ii) will not promote, recommend, endorse, or solicit participants in the deferred compensation plan to purchase any financial products or services outside of the deferred compensation plan, except that links to parts of the recordkeeper's website that are generally available to the public, are about commercial products, and may be encountered by a participant in the regular course of navigating the recordkeeper's website will not constitute a violation of this item (ii). The System may use funds from the employee and employer contributions to defray any and all costs of creating and maintaining the plan. The System shall produce an annual report on the participation in the plan and shall make the report public.
    (b) The System shall automatically enroll in the eligible deferred compensation plan any employee of an eligible employer who first becomes a participating employee of the System on or after July 1, 2023 under an eligible automatic contribution arrangement that is subject to Section 414(w) of the Internal Revenue Code of 1986, as amended, and the United States Department of Treasury regulations promulgated thereunder. An employee who is automatically enrolled under this subsection (b) shall have 3% of his or her compensation, as defined by the plan, for each pay period deferred on a pre-tax basis into his or her account, subject to any contribution limits applicable to the plan. The Board may increase the default percentage of compensation deferred under this subsection (b).
    An employee shall have 30 days from the date on which the System provides the notice required under Section 414(w) of the Internal Revenue Code of 1986, as amended, to elect to not participate in the eligible deferred compensation plan or to elect to increase or reduce the initial amount of elective deferrals made to the plan. In the absence of such affirmative election, the employee shall be automatically enrolled in the plan on the first day of the calendar month, or as soon as administratively practicable thereafter, following the 30th day from the date on which the System provides the required notice. An employee who has been automatically enrolled in the plan under this subsection (b) may elect, within 90 days of enrollment, to withdraw from the plan and receive a refund of amounts deferred, adjusted by applicable earnings and fees. An employee making such an election shall forfeit all employer matching contributions, if any, made with respect to such refunded elective deferrals and such forfeited amounts shall be used to defray plan expenses. Any refunded elective deferrals shall be included in the employee's gross income for the taxable year in which the refund is issued.
    (c) The System may provide for one or more automatic contribution arrangements, which shall comply with all applicable Internal Revenue Service rules and regulations, in conjunction with or in lieu of the eligible automatic contribution arrangement under subsection (b), for participating employees of eligible employers whose annual earnings are limited by application of subsection (b) of Section 15-111 of this Code. The amount of elective deferrals made for the employee each pay period under an automatic contribution arrangement shall equal the default percentage specified by resolution of the Board multiplied by the employee's compensation as defined by the plan, subject to any contribution limits applicable to the plan, and shall be made on a pre-tax basis. An employee subject to this subsection (c) shall have 30 days from the date on which the System provides written notice to the employee to elect to not participate in the eligible deferred compensation plan or to elect to increase or reduce the amount of initial elective deferrals made to the plan. In the absence of such affirmative election, the employee shall be automatically enrolled in the plan beginning the first day of the calendar month, or as soon as administratively practicable thereafter, following the 30th day from the date on which the System provides the required notice.
    (d) The System may provide that the default percentage for any employee automatically enrolled in the eligible deferred compensation plan under subsection (b) or (c) be increased by a specified percentage each plan year after the plan year in which the employee is automatically enrolled in the plan. The amount of automatic annual increases in any plan year shall not exceed 1% of compensation as defined by the plan.
    (e) The changes made to this Section by this amendatory Act of the 102nd General Assembly are corrections of existing law and are intended to be retroactive to the effective date of Public Act 100-769, notwithstanding Section 1-103.1 of this Code.

    (Text of Section from P.A. 103-17)
    Sec. 16-127. Computation of creditable service.
    (a) Each member shall receive regular credit for all service as a teacher from the date membership begins, for which satisfactory evidence is supplied and all contributions have been paid.
    (b) The following periods of service shall earn optional credit and each member shall receive credit for all such service for which satisfactory evidence is supplied and all contributions have been paid as of the date specified:
        (1) Prior service as a teacher.
        (2) Service in a capacity essentially similar or
    
equivalent to that of a teacher, in the public common schools in school districts in this State not included within the provisions of this System, or of any other State, territory, dependency or possession of the United States, or in schools operated by or under the auspices of the United States, or under the auspices of any agency or department of any other State, and service during any period of professional speech correction or special education experience for a public agency within this State or any other State, territory, dependency or possession of the United States, and service prior to February 1, 1951 as a recreation worker for the Illinois Department of Public Safety, for a period not exceeding the lesser of 2/5 of the total creditable service of the member or 10 years. The maximum service of 10 years which is allowable under this paragraph shall be reduced by the service credit which is validated by other retirement systems under paragraph (i) of Section 15-113 and paragraph 1 of Section 17-133. Credit granted under this paragraph may not be used in determination of a retirement annuity or disability benefits unless the member has at least 5 years of creditable service earned subsequent to this employment with one or more of the following systems: Teachers' Retirement System of the State of Illinois, State Universities Retirement System, and the Public School Teachers' Pension and Retirement Fund of Chicago. Whenever such service credit exceeds the maximum allowed for all purposes of this Article, the first service rendered in point of time shall be considered. The changes to this subdivision (b)(2) made by Public Act 86-272 shall apply not only to persons who on or after its effective date (August 23, 1989) are in service as a teacher under the System, but also to persons whose status as such a teacher terminated prior to such effective date, whether or not such person is an annuitant on that date.
        (3) Any periods immediately following teaching
    
service, under this System or under Article 17, (or immediately following service prior to February 1, 1951 as a recreation worker for the Illinois Department of Public Safety) spent in active service with the military forces of the United States; periods spent in educational programs that prepare for return to teaching sponsored by the federal government following such active military service; if a teacher returns to teaching service within one calendar year after discharge or after the completion of the educational program, a further period, not exceeding one calendar year, between time spent in military service or in such educational programs and the return to employment as a teacher under this System; and a period of up to 2 years of active military service not immediately following employment as a teacher.
        The changes to this Section and Section 16-128
    
relating to military service made by P.A. 87-794 shall apply not only to persons who on or after its effective date are in service as a teacher under the System, but also to persons whose status as a teacher terminated prior to that date, whether or not the person is an annuitant on that date. 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 P.A. 87-794 shall be included in the calculation of automatic annual increases accruing after the effective date of the recalculation.
        Credit for military service shall be determined as
    
follows: if entry occurs during the months of July, August, or September and the member was a teacher at the end of the immediately preceding school term, credit shall be granted from July 1 of the year in which he or she entered service; if entry occurs during the school term and the teacher was in teaching service at the beginning of the school term, credit shall be granted from July 1 of such year. In all other cases where credit for military service is allowed, credit shall be granted from the date of entry into the service.
        The total period of military service for which credit
    
is granted shall not exceed 5 years for any member unless the service: (A) is validated before July 1, 1964, and (B) does not extend beyond July 1, 1963. Credit for military service shall be granted under this Section only if not more than 5 years of the military service for which credit is granted under this Section is used by the member to qualify for a military retirement allotment from any branch of the armed forces of the United States. The changes to this subdivision (b)(3) made by Public Act 86-272 shall apply not only to persons who on or after its effective date (August 23, 1989) are in service as a teacher under the System, but also to persons whose status as such a teacher terminated prior to such effective date, whether or not such person is an annuitant on that date.
        (4) Any periods served as a member of the General
    
Assembly.
        (5)(i) Any periods for which a teacher, as defined in
    
Section 16-106, is granted a leave of absence, provided he or she returns to teaching service creditable under this System or the State Universities Retirement System following the leave; (ii) periods during which a teacher is involuntarily laid off from teaching, provided he or she returns to teaching following the lay-off; (iii) periods prior to July 1, 1983 during which a teacher ceased covered employment due to pregnancy, provided that the teacher returned to teaching service creditable under this System or the State Universities Retirement System following the pregnancy and submits evidence satisfactory to the Board documenting that the employment ceased due to pregnancy; and (iv) periods prior to July 1, 1983 during which a teacher ceased covered employment for the purpose of adopting an infant under 3 years of age or caring for a newly adopted infant under 3 years of age, provided that the teacher returned to teaching service creditable under this System or the State Universities Retirement System following the adoption and submits evidence satisfactory to the Board documenting that the employment ceased for the purpose of adopting an infant under 3 years of age or caring for a newly adopted infant under 3 years of age. However, total credit under this paragraph (5) may not exceed 3 years.
        Any qualified member or annuitant may apply for
    
credit under item (iii) or (iv) of this paragraph (5) without regard to whether service was terminated before the effective date of this amendatory Act of 1997. In the case of an annuitant who establishes credit under item (iii) or (iv), the annuity shall be recalculated to include the additional service credit. The increase in annuity shall take effect on the date the System receives written notification of the annuitant's intent to purchase the credit, if the required evidence is submitted and the required contribution paid within 60 days of that notification, otherwise on the first annuity payment date following the System's receipt of the required evidence and contribution. The increase in an annuity recalculated under this provision shall be included in the calculation of automatic annual increases in the annuity accruing after the effective date of the recalculation.
        Optional credit may be purchased under this
    
subsection (b)(5) for periods during which a teacher has been granted a leave of absence pursuant to Section 24-13 of the School Code. A teacher whose service under this Article terminated prior to the effective date of P.A. 86-1488 shall be eligible to purchase such optional credit. If a teacher who purchases this optional credit is already receiving a retirement annuity under this Article, the annuity shall be recalculated as if the annuitant had applied for the leave of absence credit at the time of retirement. The difference between the entitled annuity and the actual annuity shall be credited to the purchase of the optional credit. The remainder of the purchase cost of the optional credit shall be paid on or before April 1, 1992.
        The change in this paragraph made by Public Act
    
86-273 shall be applicable to teachers who retire after June 1, 1989, as well as to teachers who are in service on that date.
        (6) Any days of unused and uncompensated accumulated
    
sick leave earned by a teacher. The service credit granted under this paragraph shall be the ratio of the number of unused and uncompensated accumulated sick leave days to 170 days, subject to a maximum of 2 years of service credit. Prior to the member's retirement, each former employer shall certify to the System the number of unused and uncompensated accumulated sick leave days credited to the member at the time of termination of service. The period of unused sick leave shall not be considered in determining the effective date of retirement. A member is not required to make contributions in order to obtain service credit for unused sick leave.
        Credit for sick leave shall, at retirement, be
    
granted by the System for any retiring regional or assistant regional superintendent of schools at the rate of 6 days per year of creditable service or portion thereof established while serving as such superintendent or assistant superintendent.
        (7) Periods prior to February 1, 1987 served as an

To receive credit under this item (10), a teacher must apply in writing to the Board and pay the required contributions before May 1, 1993 and have at least 12 years of service credit under this Article.
    (b-1) A member may establish optional credit for up to 2 years of service as a teacher or administrator employed by a private school recognized by the Illinois State Board of Education, provided that the teacher (i) was certified under the law governing the certification of teachers at the time the service was rendered, (ii) applies in writing on or before June 30, 2028, (iii) supplies satisfactory evidence of the employment, (iv) completes at least 10 years of contributing service as a teacher as defined in Section 16-106, and (v) pays the contribution required in subsection (d-5) of Section 16-128. The member may apply for credit under this subsection and pay the required contribution before completing the 10 years of contributing service required under item (iv), but the credit may not be used until the item (iv) contributing service requirement has been met.
    (c) The service credits specified in this Section shall be granted only if: (1) such service credits are not used for credit in any other statutory tax-supported public employee retirement system other than the federal Social Security program; and (2) the member makes the required contributions as specified in Section 16-128. Except as provided in subsection (b-1) of this Section, the service credit shall be effective as of the date the required contributions are completed.

However, for military service not immediately following employment, the salary rate on the last date as a participating teacher prior to such military service, or on the first date as a participating teacher after such military service, whichever is greater, shall be assumed to be equal to the member's salary rate at the time of entering military service. For each school term thereafter, the member's salary rate shall be assumed to be 5% higher than the salary rate in the previous school term.
    (d) In determining the contribution required in order to receive creditable service under paragraph (5) of subsection (b) of Section 16-127, a member's salary rate during the period for which credit is being established shall be assumed to be equal to the member's last salary rate immediately preceding that period.
    (d-5) For each year of service credit to be established under subsection (b-1) of Section 16-127, a member is required to contribute to the System (i) the employee and employer contribution that would have been required had such service been rendered as a member based on the annual salary rate during the first year of full-time employment as a teacher under this Article following the private or parochial school service, plus (ii) interest thereon at the actuarially assumed rate from the date of first full-time employment as a teacher under this Article following the private or parochial school service to the date of payment, compounded annually, at a rate determined by the Board.
    (d-10) For service credit established under paragraph (6) of subsection (b) of Section 16-127 for days granted by an employer in excess of the member's normal annual sick leave allotment, the employer is required to pay the normal cost of benefits based upon such service credit. This subsection (d-10) does not apply to sick leave granted to teachers under contracts or collective bargaining agreements entered into, amended, or renewed before June 1, 2005 (the effective date of Public Act 94-4). The employer contributions required under this subsection (d-10) shall be paid in the form of a lump sum within 30 days after receipt of the bill after the teacher begins receiving benefits under this Article.
    (e) Except for contributions under subsection (d-10), the contributions required under this Section may be made from the date the statement for such creditable service is issued until retirement date. All such required contributions must be made before any retirement annuity is granted.

    (b) The contribution shall be an amount equal to 1.0% of the member's highest salary rate in the 4 consecutive school years immediately prior to but not including the school year in which the application occurs, multiplied by the number of years of creditable service earned by the member before July 1, 1998 or 20, whichever is less. This contribution shall be reduced by 1.0% of that salary rate for every 3 full years of creditable service earned by the member after June 30, 1998. The contribution shall be further reduced at the rate of 25% of the contribution (as reduced for service after June 30, 1998) for each year of the member's total creditable service in excess of 34 years. The contribution shall not in any event exceed 20% of that salary rate.
    The member shall pay to the System the amount of the contribution as calculated at the time of application under this Section. The amount of the contribution determined under this subsection shall be recalculated at the time of retirement, and if the System determines that the amount paid by the member exceeds the recalculated amount, the System shall refund the difference to the member with regular interest from the date of payment to the date of refund.
    The contribution required by this subsection shall be paid in one of the following ways or in a combination of the following ways that does not extend over more than 5 years:
        (i) in a lump sum on or before the date of retirement;
        (ii) in substantially equal installments over a
    
period of time not to exceed 5 years, as a deduction from salary in accordance with subsection (b) of Section 16-154;
        (iii) in substantially equal monthly installments
    
over a 24-month period, by reducing the annuitant's monthly benefit over a 24-month period by the amount of the otherwise applicable contribution. For federal and Illinois tax purposes, the monthly amount by which the annuitant's benefit is reduced shall not be treated as a contribution by the annuitant, but rather as a reduction of the annuitant's monthly benefit.
    (c) If the member fails to make the full contribution under this Section in a timely fashion, the payments made under this Section shall be refunded to the member, without interest. If the member dies before making the full contribution, the payments made under this Section, together with regular interest thereon, shall be refunded to the member's designated beneficiary for benefits under Section 16-138.
    (d) For purposes of this Section and subdivision (a)(B)(1) of Section 16-133, optional creditable service established by a member shall be deemed to have been earned at the time of the employment or other qualifying event upon which the service is based, rather than at the time the credit was established in this System.
    (e) The contributions required under this Section are the responsibility of the teacher and not the teacher's employer. However, an employer of teachers may, after the effective date of this amendatory Act of 1998, specifically agree, through collective bargaining or otherwise, to make the contributions required by this Section on behalf of those teachers.
    (f) A person who, on or after July 1, 1998 and before June 4, 1999, began receiving a retirement annuity calculated at the augmented rate may apply in writing to have the annuity recalculated to reflect the changes to this Section and Section 16-133 that were enacted in Public Act 91-17. The amount of any resulting decrease in the optional contribution shall be refunded to the annuitant, without interest. Any resulting increase in retirement annuity shall take effect on the next annuity payment date following the date of application under this subsection.

    Sec. 16-130. Creditable service - whole or portion of year.
    (a) Except as provided in paragraph (6) of subsection (b) of Section 16-127, only one year of service is creditable for all service in any one school year.
    (b) For employment prior to July 1, 1990, service rendered for the regular legal school term, if creditable hereunder, is equivalent to one year of service, and time less than a legal school term shall be counted as a portion of a year in the ratio that the number of days paid bears to the number of days required at the time to constitute a legal school term; however, service of 170 or more days in any school year after June 30, 1959 shall constitute a year of service.
    (c) Creditable service for periods of employment after June 30, 1990 shall be calculated as follows:
    For full-time, part-time, and substitute teachers, creditable service in any school year shall be that fraction of a year equal to the ratio of days paid in the legal school term, or the employment agreement if longer, to 170 days.
    (d) Creditable service for optional service verified after July 1, 1990 for periods of employment prior to July 1, 1990 shall be calculated as follows:
    For full-time, part-time, and substitute teachers, creditable service in any school year shall be that fraction of a year that is equal to the ratio of days paid in the legal school term, or employment agreement if longer, to either the number of days required at the time of service to constitute a legal school term or the number of days in the employment agreement, whichever is greater. However, service of 170 or more days in any school year after June 30, 1959 shall constitute a year of service.
