Okla. Stat. tit. 36, § 2018

Any member insurer who has paid an assessment pursuant to the Oklahoma Property and Casualty Insurance Guaranty Association Act shall include amounts sufficient to recoup a sum equal to the amounts paid to the Oklahoma Property and Casualty Insurance Guaranty Association by the member insurer, less any amounts returned to the member insurer by the Association. Rates shall not be deemed excessive because they contain an additional amount reasonably calculated to recoup all assessments paid by the member insurer in its next filing for a rate increase or decrease before the Insurance Commissioner.
