    Sec. 401. Weekly Benefit Amount - Dependents' Allowances.
    A. With respect to any week beginning in a benefit year beginning prior to January 4, 2004, an individual's weekly benefit amount shall be an amount equal to the weekly benefit amount as defined in the provisions of this Act as amended and in effect on November 18, 2011.
    B. 1. With respect to any benefit year beginning on or after January 4, 2004 and before January 6, 2008, an individual's weekly benefit amount shall be 48% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; provided, however, that the weekly benefit amount cannot exceed the maximum weekly benefit amount and cannot be less than $51. Except as otherwise provided in this Section, with respect to any benefit year beginning on or after January 6, 2008, an individual's weekly benefit amount shall be 47% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; provided, however, that the weekly benefit amount cannot exceed the maximum weekly benefit amount and cannot be less than $51. With respect to any benefit year beginning in calendar year 2020, an individual's weekly benefit amount shall be 40.3% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; provided, however, that the weekly benefit amount cannot exceed the maximum weekly benefit amount and cannot be less than $51.
    2. For the purposes of this subsection:
    An individual's "prior average weekly wage" means the total wages for insured work paid to that individual during the 2 calendar quarters of his base period in which such total wages were highest, divided by 26. If the quotient is not already a multiple of one dollar, it shall be rounded to the nearest dollar; however if the quotient is equally near 2 multiples of one dollar, it shall be rounded to the higher multiple of one dollar.
    "Determination date" means June 1 and December 1 of each calendar year except that, for the purposes of this Act only, there shall be no June 1 determination date in any year.
    "Determination period" means, with respect to each June 1 determination date, the 12 consecutive calendar months ending on the immediately preceding December 31 and, with respect to each December 1 determination date, the 12 consecutive calendar months ending on the immediately preceding June 30.
    "Benefit period" means the 12 consecutive calendar month period beginning on the first day of the first calendar month immediately following a determination date, except that, with respect to any calendar year in which there is a June 1 determination date, "benefit period" shall mean the 6 consecutive calendar month period beginning on the first day of the first calendar month immediately following the preceding December 1 determination date and the 6 consecutive calendar month period beginning on the first day of the first calendar month immediately following the June 1 determination date.
    "Gross wages" means all the wages paid to individuals during the determination period immediately preceding a determination date for insured work, and reported to the Director by employers prior to the first day of the third calendar month preceding that date.
    "Covered employment" for any calendar month means the total number of individuals, as determined by the Director, engaged in insured work at mid-month.
    "Average monthly covered employment" means one-twelfth of the sum of the covered employment for the 12 months of a determination period.
    "Statewide average annual wage" means the quotient, obtained by dividing gross wages by average monthly covered employment for the same determination period, rounded (if not already a multiple of one cent) to the nearest cent.
    "Statewide average weekly wage" means the quotient, obtained by dividing the statewide average annual wage by 52, rounded (if not already a multiple of one cent) to the nearest cent. Notwithstanding any provision of this Section to the contrary, the statewide average weekly wage for any benefit period prior to calendar year 2012 shall be as determined by the provisions of this Act as amended and in effect on November 18, 2011. Notwithstanding any provisions of this Section to the contrary, the statewide average weekly wage for the benefit period of calendar year 2012 shall be $856.55 and for each calendar year thereafter, the statewide average weekly wage shall be the statewide average weekly wage, as determined in accordance with this sentence, for the immediately preceding benefit period plus (or minus) an amount equal to the percentage change in the statewide average weekly wage, as computed in accordance with the first sentence of this paragraph, between the 2 immediately preceding benefit periods, multiplied by the statewide average weekly wage, as determined in accordance with this sentence, for the immediately preceding benefit period. However, for purposes of the Workers' Compensation Act, the statewide average weekly wage will be computed using June 1 and December 1 determination dates of each calendar year and such determination shall not be subject to the limitation of the statewide average weekly wage as computed in accordance with the preceding sentence of this paragraph.
    With respect to any week beginning in a benefit year beginning prior to January 4, 2004, "maximum weekly benefit amount" with respect to each week beginning within a benefit period shall be as defined in the provisions of this Act as amended and in effect on November 18, 2011.
    With respect to any benefit year beginning on or after January 4, 2004 and before January 6, 2008, "maximum weekly benefit amount" with respect to each week beginning within a benefit period means 48% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar.
    Except as otherwise provided in this Section, with respect to any benefit year beginning on or after January 6, 2008, "maximum weekly benefit amount" with respect to each week beginning within a benefit period means 47% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar.
    With respect to any benefit year beginning in calendar year 2020, "maximum weekly benefit amount" with respect to each week beginning within a benefit period means 40.3% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar.
    C. With respect to any week beginning in a benefit year beginning prior to January 4, 2004, an individual's eligibility for a dependent allowance with respect to a nonworking spouse or one or more dependent children shall be as defined by the provisions of this Act as amended and in effect on November 18, 2011.

    With respect to any benefit year beginning on or after January 6, 2008 and before January 1, 2010, an individual to whom benefits are payable with respect to any week shall, in addition to those benefits, be paid, with respect to such week, as follows: in the case of an individual with a nonworking spouse, 9% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, provided, that the total amount payable to the individual with respect to a week shall not exceed 56% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; and in the case of an individual with a dependent child or dependent children, 18.2% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, provided that the total amount payable to the individual with respect to a week shall not exceed 65.2% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar.
    The additional amount paid pursuant to this subsection in the case of an individual with a dependent child or dependent children shall be referred to as the "dependent child allowance", and the percentage rate by which an individual's prior average weekly wage is multiplied pursuant to this subsection to calculate the dependent child allowance shall be referred to as the "dependent child allowance rate".
    Except as otherwise provided in this Section, with respect to any benefit year beginning on or after January 1, 2010, an individual to whom benefits are payable with respect to any week shall, in addition to those benefits, be paid, with respect to such week, as follows: in the case of an individual with a nonworking spouse, the greater of (i) 9% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, or (ii) $15, provided that the total amount payable to the individual with respect to a week shall not exceed 56% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; and in the case of an individual with a dependent child or dependent children, the greater of (i) the product of the dependent child allowance rate multiplied by his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, or (ii) the lesser of $50 or 50% of his or her weekly benefit amount, rounded (if not already a multiple of one dollar) to the next higher dollar, provided that the total amount payable to the individual with respect to a week shall not exceed the product of the statewide average weekly wage multiplied by the sum of 47% plus the dependent child allowance rate, rounded (if not already a multiple of one dollar) to the next higher dollar.
    With respect to any benefit year beginning in calendar year 2020, an individual to whom benefits are payable with respect to any week shall, in addition to those benefits, be paid, with respect to such week, as follows: in the case of an individual with a nonworking spouse, the greater of (i) 9% of his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, or (ii) $15, provided that the total amount payable to the individual with respect to a week shall not exceed 49.3% of the statewide average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar; and in the case of an individual with a dependent child or dependent children, the greater of (i) the product of the dependent child allowance rate multiplied by his or her prior average weekly wage, rounded (if not already a multiple of one dollar) to the next higher dollar, or (ii) the lesser of $50 or 50% of his or her weekly benefit amount, rounded (if not already a multiple of one dollar) to the next higher dollar, provided that the total amount payable to the individual with respect to a week shall not exceed the product of the statewide average weekly wage multiplied by the sum of 40.3% plus the dependent child allowance rate, rounded (if not already a multiple of one dollar) to the next higher dollar.
