(a) Average monthly employment in the calendar year preceding the calculation shall be divided by the average monthly employment in the high benefit cost period with the resulting quotient carried to the fourth decimal place.

(b) The adjusted average weekly check amount for the calendar year preceding the calculation shall be divided by the average weekly check amount in the high benefit cost period with the resulting quotient carried to the fourth decimal place.

(c) The amount of benefits paid during the high benefit cost period and attributable to employers subject to the tax shall be multiplied by the quotient determined in paragraph (a) of this subsection.

(3) Notwithstanding the provisions of subsection (2) of this section, if the product obtained by multiplying 3.0 times the average monthly employment in the calendar year preceding the calculation times the adjusted average weekly check amount for the calendar year preceding the computation exceeds the amount determined in subsection (1)(c) of this section, such product shall be used in lieu of the amount determined in subsection (1)(c) of this section in the Trust Fund Adequacy Ratio calculation in subsection (2) of this section.

(4) Products obtained in subsections (1) and (3) of this section shall be rounded to the nearest dollar. [1969 c.157 §3 (657.458 and 657.459 enacted in lieu of 657.461); 1971 c.463 §16; 1975 c.354 §2; 1977 c.538 §4; 1983 c.508 §10; 2005 c.22 §462; 2005 c.183 §7]
