1. As soon as practicable after January 1 of each year, the commissioners of the Workers' Compensation Commission shall establish an assessment rate applicable to each mutual or interinsurance association, stock company, or other insurance carrier writing workers' compensation insurance in this state, each employer carrying its own risk, and each group self-insurance association, for amounts for purposes of computing the assessment authorized by this section necessary to pay the annual obligations of the Multiple Injury Trust Fund determined on or before December 31 of each year by the Multiple Injury Trust Fund (MITF) Director, provided for in subsection Q of this section, to be outstanding for the next calendar year. The rate shall be equal for all parties required to pay the assessment. The Board of Directors for CompSource Mutual Insurance Company shall have the power to disapprove the rate established by the MITF Director until the Multiple Injury Trust Fund repays in full the amount due on any loan from CompSource Mutual Insurance Company or its predecessor CompSource Oklahoma.

Insurance carriers, self-insurers, and group self-insurance associations shall pay the assessment in four equal installments not later than the fifteenth day of the month following the close of each quarter of the calendar year of the assessment. Assessments shall be determined based upon gross direct written premiums, normal premiums or actual paid losses of the paying party, as applicable, during the calendar quarter for which the assessment is due. Assessments are expressly conditioned and contingent upon preservation of the rebate equal to two-thirds ( ²/₃ ) of the amount of the assessment actually paid pursuant to Sections 6101 and 6102 of Title 68 of the Oklahoma Statutes. Uninsured employers shall pay the assessment not later than the fifteenth day of the month following the close of each quarter of the calendar year of the assessment.

The rate determined by the Commission shall be in effect for four calendar quarters beginning July 1 following determination by the Commission. The Commission may amend its previously determined rate on or after July 1, 2019. Parties affected by the amended rate shall be notified by the Commission in writing as is reasonable;

6. The Oklahoma Tax Commission shall assess and collect from any uninsured employer a temporary assessment at the rate of five percent (5%) of the total compensation for permanent total disability awards, permanent partial disability awards and death benefits paid out during each quarter of the calendar year by employers. The assessment shall be paid in four equal installments not later than the fifteenth day of the month following the close of the calendar year of the assessments.

On or before the first day of November of each year, the State Treasurer shall advise the Commission, the MITF Director and the Tax Commission of the amount of money held as of October 1 of that year by the State Treasurer to the credit of the Multiple Injury Trust Fund.
