To enable the corporation commission to perform its lawful duties relating to classifications to be used, rates and charges to be made and collected, rules and regulations to be prescribed, and supervision over public service corporations, the commission shall annually make an assessment against each such corporation, excepting corporations not required to hold certificates of convenience and necessity.B. The amount of the assessment to be made against each corporation pursuant to subsection A of this section shall be computed as follows:1. Determine the amount appropriated by the legislature for operating the utilities division and a part of the administration, hearing and legal divisions for the following fiscal year.2. Multiply the amount determined in paragraph 1 by 1.2.3. Subtract the monies estimated to remain unexpended in the utility regulation revolving fund at the end of the current fiscal year from the amount determined in paragraph 2. The difference is the total amount to be raised by the assessment.4. Add the gross operating revenues derived from intrastate operations during the preceding calendar year for all corporations whose revenues reported pursuant to subsection F of this section were greater than five hundred thousand dollars.5. For each corporation whose gross operating revenues derived from intrastate operations during the preceding calendar year reported pursuant to subsection F of this section were greater than five hundred thousand dollars:(a) Divide the corporation's gross operating revenues by the amount determined in paragraph 4.(b) Multiply the total amount to be raised by the assessment determined in paragraph 3 by the amount determined in subdivision (a). The product is the amount of the assessment to be made against the corporation pursuant to this section.C. Notwithstanding the amounts determined in subsection B of this section and section 40-401.01, subsection B, the sum of the amounts assessed under this section and section 40-401.01 shall not exceed one-quarter of one per cent of any such corporation's gross operating revenues derived from intrastate operations during the preceding calendar year.D.
