Ohio Revised Code Title XXXIX. Insurance § 3955.17

(A) A rate shall not be found excessive under section 3935.03 or 3937.02 of the Revised Code solely because it contains a factor designed to recover any amounts paid to the Ohio insurance guaranty association by a member insurer as an assessment under division (A)(3) of section 3955.08 of the Revised Code from sources other than such fund.

(B) The rates subject to section 3935.03 or 3937.02 of the Revised Code may include an amount necessary to recoup assessments paid or payable to the Ohio insurance guaranty association made pursuant to division (A)(3) of section 3955.08 of the Revised Code and reasonable expenses and costs attributable to payment and recoupment of the assessment. The association may establish a plan whereby assessments or projected assessments due from member insurers may be payable periodically. Such plan may also provide for the calculation and use of rates or rating factors necessary to recoup such assessments, subject to the approval of the superintendent. Member insurers of the association implementing a change in rates pursuant to the plan shall file such changes with the superintendent, provided such changes shall not increase rates more than the amount authorized by the association and approved by the superintendent pursuant to the plan. The association may consult with member insurers or licensed rating bureaus in connection with the establishment and operation of any such plan.
