Ohio Rev. Code § 3935.11
The superintendent of insurance shall, at least once in five years, make an examination of each rating bureau licensed in this state as provided in section 3935.06 of the Revised Code, and he may, as often as he considers it expedient, make an examination of each advisory organization referred to in section 3935.12 of the Revised Code and of each group, association, or other organization referred to in section 3935.13 of the Revised Code. The reasonable costs of any such examination shall be paid by the rating bureau, advisory organization, group, association, or other organization examined upon presentation to it of a detailed account of such costs. The officers, manager, agents, and employees of such rating bureau, advisory organization, group, association, or other organization may be examined at any time under oath and shall exhibit all books, records, accounts, documents, or agreements governing its method of operation. The superintendent shall furnish two copies of the examination report to the rating bureau, advisory organization, group, or association examined and shall notify such rating bureau, advisory organization, group, or association that it may, within twenty days thereafter, request a hearing on said report or on any facts or recommendations therein. Before filing any such report for public inspection, the superintendent shall grant a hearing to the rating bureau, advisory organization, group, or association examined. The report of any such examination, when filed for public inspection, is admissible in evidence in any action or proceeding brought by the superintendent against the rating bureau, advisory organization, group, or association examined, or its officers or agents, and is prima-facie evidence of the facts stated therein. The superintendent may withhold the report of any such examination from public inspection for such time as he considers proper. In lieu of any such examination the superintendent may accept the report of an examination made by the insurance supervisory official of another state, pursuant to the laws of such state.
