40 ILCS 5/16-158
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 (b-3).
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 Public Act 94-4.
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.
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 subsection, the difference shall be paid from the Common School Fund under the continuing appropriation authority provided in Section 1.1 of the State Pension Funds Continuing Appropriation Act.
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; except that in the following specified State fiscal years, the State contribution to the System shall not be less than the following indicated percentages of the applicable employee payroll, even if the indicated percentage will produce a State contribution in excess of the amount otherwise required under this subsection and subsection (a), and notwithstanding any contrary certification made under subsection (a-1) before May 27, 1998 (the effective date of Public Act 90-582): 10.02% in FY 1999; 10.77% in FY 2000; 11.47% in FY 2001; 12.16% in FY 2002; 12.86% in FY 2003; and 13.56% in FY 2004.
Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2006 is $534,627,700.
Notwithstanding any other provision of this Article, the total required State contribution for State fiscal year 2007 is $738,014,500.
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 $2,089,268,000 and shall be made from the 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 Common School Fund in fiscal year 2010, and (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 subsection (a-1) of this Section and shall be made from the 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 Common School Fund in fiscal year 2011, and (iii) any reduction in bond proceeds due to the issuance of discounted bonds, if applicable. This amount shall include, in addition to the amount certified by the System, an amount necessary to meet employer contributions required by the State as an employer under paragraph (e) of this Section, which may also be used by the System for contributions required by paragraph (a) of Section 16-127.
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 subsection (a-1), 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 (b-4) 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.
If members are paid from special trust or federal funds which are administered by the employing unit, whether school district or other unit, the employing unit shall pay to the System from such funds the full accruing retirement costs based upon that service, which, beginning July 1, 2017, shall be at a rate, expressed as a percentage of salary, equal to the total employer's normal cost, expressed as a percentage of payroll, as determined by the System. Employer contributions, based on salary paid to members from federal funds, may be forwarded by the distributing agency of the State of Illinois to the System prior to allocation, in an amount determined in accordance with guidelines established by such agency and the System. Any contribution for fiscal year 2015 collected as a result of the change made by Public Act 98-674 shall be considered a State contribution under subsection (b-3) of this Section.
However, with respect to benefits granted under Section 16-133.4 or 16-133.5 to a teacher as defined in paragraph (8) of Section 16-106, the employer's contribution shall be 12% (rather than 20%) of the member's highest annual salary rate for each year of creditable service granted, and the employer shall also pay the required employee contribution on behalf of the teacher. For the purposes of Sections 16-133.4 and 16-133.5, a teacher as defined in paragraph (8) of Section 16-106 who is serving in that capacity while on leave of absence from another employer under this Article shall not be considered an employee of the employer from which the teacher is on leave.
The school district or other employing unit may pay these employer contributions out of any source of funding available for that purpose and shall forward the contributions to the System on the schedule established for the payment of member contributions.
These employer contributions are intended to offset a portion of the cost to the System of the increases in retirement benefits resulting from Public Act 90-582.
Each employer of teachers is entitled to a credit against the contributions required under this subsection (e) with respect to salaries paid to teachers for the period January 1, 2002 through June 30, 2003, equal to the amount paid by that employer under subsection (a-5) of Section 6.6 of the State Employees Group Insurance Act of 1971 with respect to salaries paid to teachers for that period.
The additional 1% employee contribution required under Section 16-152 by Public Act 90-582 is the responsibility of the teacher and not the teacher's employer, unless the employer agrees, through collective bargaining or otherwise, to make the contribution on behalf of the teacher.
If an employer is required by a contract in effect on May 1, 1998 between the employer and an employee organization to pay, on behalf of all its full-time employees covered by this Article, all mandatory employee contributions required under this Article, then the employer shall be excused from paying the employer contribution required under this subsection (e) for the balance of the term of that contract. The employer and the employee organization shall jointly certify to the System the existence of the contractual requirement, in such form as the System may prescribe. This exclusion shall cease upon the termination, extension, or renewal of the contract at any time after May 1, 1998.
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 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 (g), (g-5), (g-10), (g-15), (g-20), or (h) 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 (f) 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 subsection (f), the System shall exclude salary increases paid to teachers under contracts or collective bargaining agreements entered into, amended, or renewed before June 1, 2005.
When assessing payment for any amount due under subsection (f), the System shall exclude salary increases paid to a teacher at a time when the teacher is 10 or more years from retirement eligibility under Section 16-132 or 16-133.2.
When assessing payment for any amount due under subsection (f), the System shall exclude salary increases resulting from overload work, including summer school, when the school district has certified to the System, and the System has approved the certification, that (i) the overload work is for the sole purpose of classroom instruction in excess of the standard number of classes for a full-time teacher in a school district during a school year and (ii) the salary increases are equal to or less than the rate of pay for classroom instruction computed on the teacher's current salary and work schedule.
When assessing payment for any amount due under subsection (f), the System shall exclude a salary increase resulting from a promotion (i) for which the employee is required to hold a certificate or supervisory endorsement issued by the State Teacher Certification Board that is a different certification or supervisory endorsement than is required for the teacher's previous position and (ii) to a position that has existed and been filled by a member for no less than one complete academic year and the salary increase from the promotion is an increase that results in an amount no greater than the lesser of the average salary paid for other similar positions in the district requiring the same certification or the amount stipulated in the collective bargaining agreement for a similar position requiring the same certification.
When assessing payment for any amount due under subsection (f), the System shall exclude any payment to the teacher from the State of Illinois or the State Board of Education over which the employer does not have discretion, notwithstanding that the payment is included in the computation of final average salary.
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 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. 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 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.
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.
