40 ILCS 5/15-155
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).
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:
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.
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.
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.
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.
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).
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.
