(820 ILCS 405/1505) (from Ch. 48, par. 575)
    Sec. 1505. Adjustment of state experience factor. The state experience factor shall be adjusted in accordance with the following provisions:
    A. For calendar years prior to 1988, the state experience factor shall be adjusted in accordance with the provisions of this Act as amended and in effect on November 18, 2011.
    B. (Blank).
    C. For calendar year 1988 and each calendar year thereafter, for which the state experience factor is being determined.
        1. For every $50,000,000 (or fraction thereof) by
    
which the adjusted trust fund balance falls below the target balance set forth in this subsection, the state experience factor for the succeeding year shall be increased one percent absolute.
        For every $50,000,000 (or fraction thereof) by which
    
the adjusted trust fund balance exceeds the target balance set forth in this subsection, the state experience factor for the succeeding year shall be decreased by one percent absolute.
        The target balance in each calendar year prior to
    
2003 is $750,000,000. The target balance in calendar year 2003 is $920,000,000. The target balance in calendar year 2004 is $960,000,000. The target balance in calendar year 2005 and each calendar year thereafter is $1,000,000,000.
        2. For the purposes of this subsection:
        "Net trust fund balance" is the amount standing to
    
the credit of this State's account in the unemployment trust fund as of June 30 of the calendar year immediately preceding the year for which a state experience factor is being determined.
        "Adjusted trust fund balance" is the net trust fund
    
balance minus the sum of the benefit reserves for fund building for July 1, 1987 through June 30 of the year prior to the year for which the state experience factor is being determined. The adjusted trust fund balance shall not be less than zero. If the preceding calculation results in a number which is less than zero, the amount by which it is less than zero shall reduce the sum of the benefit reserves for fund building for subsequent years.
        For the purpose of determining the state experience
    
factor for 1989 and for each calendar year thereafter, the following "benefit reserves for fund building" shall apply for each state experience factor calculation in which that 12 month period is applicable:
            a. For the 12 month period ending on June 30,
        
1988, the "benefit reserve for fund building" shall be 8/104th of the total benefits paid from January 1, 1988 through June 30, 1988.
            b. For the 12 month period ending on June 30,
        
1989, the "benefit reserve for fund building" shall be the sum of:
                i. 8/104ths of the total benefits paid from
            
July 1, 1988 through December 31, 1988, plus
                ii. 4/108ths of the total benefits paid from
            
January 1, 1989 through June 30, 1989.
            c. For the 12 month period ending on June 30,
        
1990, the "benefit reserve for fund building" shall be 4/108ths of the total benefits paid from July 1, 1989 through December 31, 1989.
            d. For 1992 and for each calendar year
        
thereafter, the "benefit reserve for fund building" for the 12 month period ending on June 30, 1991 and for each subsequent 12 month period shall be zero.
        3. Notwithstanding the preceding provisions of this
    
subsection, for calendar years 1988 through 2003, the state experience factor shall not be increased or decreased by more than 15 percent absolute.
    D. Notwithstanding the provisions of subsection C, the adjusted state experience factor:
        1. Shall be 111 percent for calendar year 1988;
        2. Shall not be less than 75 percent nor greater than
    
135 percent for calendar years 1989 through 2003; and shall not be less than 75% nor greater than 150% for calendar year 2004 and each calendar year thereafter, not counting any increase pursuant to subsection D-1, D-2, or D-3;
        3. Shall not be decreased by more than 5 percent
    
absolute for any calendar year, beginning in calendar year 1989 and through calendar year 1992, by more than 6% absolute for calendar years 1993 through 1995, by more than 10% absolute for calendar years 1999 through 2003 and by more than 12% absolute for calendar year 2004 and each calendar year thereafter, from the adjusted state experience factor of the calendar year preceding the calendar year for which the adjusted state experience factor is being determined;
        4. Shall not be increased by more than 15% absolute
    
for calendar year 1993, by more than 14% absolute for calendar years 1994 and 1995, by more than 10% absolute for calendar years 1999 through 2003 and by more than 16% absolute for calendar year 2004 and each calendar year thereafter, from the adjusted state experience factor for the calendar year preceding the calendar year for which the adjusted state experience factor is being determined;
        5. Shall be 100% for calendar years 1996, 1997, and
    
1998.
    D-1. The adjusted state experience factor for each of calendar years 2013 through 2015 shall be increased by 5% absolute above the adjusted state experience factor as calculated without regard to this subsection. The adjusted state experience factor for each of calendar years 2016 through 2018 shall be increased by 6% absolute above the adjusted state experience factor as calculated without regard to this subsection. The increase in the adjusted state experience factor for calendar year 2018 pursuant to this subsection shall not be counted for purposes of applying paragraph 3 or 4 of subsection D to the calculation of the adjusted state experience factor for calendar year 2019.
    D-2. (Blank).
    D-3. The adjusted state experience factor for calendar year 2020 shall be increased by 21% absolute above the adjusted state experience factor as calculated without regard to this subsection. The increase in the adjusted state experience factor for calendar year 2020 pursuant to this subsection shall not be counted for purposes of applying paragraph 3 or 4 of subsection D to the calculation of the adjusted state experience factor for calendar year 2021.
    E. The amount standing to the credit of this State's account in the unemployment trust fund as of June 30 shall be deemed to include as part thereof (a) any amount receivable on that date from any Federal governmental agency, or as a payment in lieu of contributions under the provisions of Sections 1403 and 1405 B and paragraph 2 of Section 302C, in reimbursement of benefits paid to individuals, and (b) amounts credited by the Secretary of the Treasury of the United States to this State's account in the unemployment trust fund pursuant to Section 903 of the Federal Social Security Act, as amended, including any such amounts which have been appropriated by the General Assembly in accordance with the provisions of Section 2100 B for expenses of administration, except any amounts which have been obligated on or before that date pursuant to such appropriation.
