Section 820 ILCS 405/1504 - State experience factorA.For each calendar year prior to 1988, the total benefits paid from this State's account in the unemployment trust fund during the 36 consecutive calendar month period ending June 30 of the calendar year immediately preceding the calendar year for which a contribution rate is being determined shall be termed the loss experience. The loss experience less all repayments (including payments in lieu of contributions pursuant to Sections 1403, 1404 and 1405B and paragraph 2 of Section 302C) to this State's account in the unemployment trust fund during the same 36 consecutive calendar month period divided by the total benefit wages of all employers for the same period, after adjustment of any fraction to the nearer multiple of one percent, shall be termed the state experience factor. Whenever such fraction is exactly one-half, it shall be adjusted to the next higher multiple of one percent.B.For calendar year 1988 and each calendar year thereafter, the state experience factor shall be the sum of all regular benefits paid plus the applicable benefit reserve for fund building, pursuant to Section 1505, during the three year period ending on June 30 of the year immediately preceding the year for which a contribution rate is being determined divided by the "net revenues" for the three year period ending on September 30 of the year immediately preceding the year for which a contribution rate is being determined, after adjustment of any fraction to the nearer multiple of one percent. Whenever such fraction is exactly one-half, it shall be adjusted to the next higher multiple of one percent. For purposes of this subsection, "Net revenue" means, for each one year period ending on September 30, the sum of the amounts, as determined pursuant to (1) and (2) of this subsection, in each quarter of such one year period.
(1) For each calendar quarter prior to the second calendar quarter of 1988, "net revenue" means all repayments (including payments in lieu of contributions pursuant to Sections 1403, 1404 and 1405B and paragraph 2 of Section 302C) to this State's account in the unemployment trust fund less "net voluntary debt repayments" during the same calendar quarter. "Net voluntary debt repayments" means an amount equal to repayments to Title XII advances less any new advances. Any such repayments made after June 30, 1987 but prior to November 10, 1987 shall be deemed to have been made prior to June 30, 1987.(2) For each calendar quarter after the first calendar quarter of 1988, "net revenue" shall be the sum of: (a) the amount determined by (i) multiplying the benefit wage or benefit ratios, pursuant to Sections 1503 or 1503.1, respectively, of all employers who have not elected to make payments in lieu of contributions applicable to the prior quarter by the state experience factor for that same quarter, (ii) adding this product to the fund building factor provided for in Section 1506.3, (iii) constraining this sum by the application of Sections 1506.1 and 1506.3, except that the State experience factor shall be substituted for the adjusted State experience factor in determining these constraints, and then (iv) multiplying this sum by the total wages for insured work subject to the payment of contributions under Sections 234, 235 and 245 of each employer for the prior quarter except that such wages shall not include those wages estimated by the Director prior to the issuance of a Determination and Assessment or those wages estimated as a result of an audit because of the employer's failure to report wages; plus (b)all payments in lieu of contributions pursuant to Sections 1403 and 1404 and subsection B of Section 1405 and paragraph 2 of subsection C of Section 302 received during the same calendar quarter. For purposes of computing "net revenue", employers who have not incurred liability for the payment of contributions for at least three years will be excluded from the calculation as will predecessor employers pursuant to Section 1507. C.The state experience factor shall be determined for each calendar year by the Director. Any change in the benefit wages or benefit charges of any employer or any change in contributions (including payments in lieu of contributions pursuant to Sections 1403 and 1404 and subsection B of Section 1405 and paragraph 2 of subsection C of Section 302) received into this State's account in the unemployment trust fund after June 30 of the calendar year immediately preceding the calendar year for which the state experience factor is being determined shall not affect the state experience factor as determined by the Director for that year.
