 (from Ch. 73, par. 1065.13)Sec. 466.     Rate administration.     (1) Recording and Reporting of Loss and Expense Experience.The Director shall promulgate reasonable rules and shall approve statistical  plans, reasonably adapted to each of the rating systems on file with him, which  may be modified from time to time and which shall be used thereafter by  each company in the recording and reporting of its loss and countrywide  expense experience, in order that the experience of all companies may be  made available at least annually in such form and detail as may be  necessary to aid him in determining whether rating systems comply with the  standards set forth in Section 456. An approved statistical plan need not  be adopted as a rule, but shall be made available for public inspection at  the Department's principal office and a copy of the plan shall be filed  with the Secretary of State. Such rules and plans may also provide  for the recording and reporting of expense experience items which are  specially applicable to this state and are not susceptible of determination  by a prorating of countrywide expense experience. In promulgating such rules  and approving plans, the Director shall give due consideration to the rating  systems on file with him and in order that such rules and plans may be as  uniform as is practicable among the several states, to the rules and to the  form of the plans used for such rating systems in other states. No company  shall be required to record or report any experience on an experience  classification which it does not use in the making of its rates or to  record or report its experience on any basis or statistical plan that  differs from that which is regularly employed and used in the usual course  of such company's business, nor shall any company be required to record or  report its loss experience on a classification basis that is inconsistent  with the rating system filed by it, nor shall it be required to report such  experience to any rating organization of which it is not a member or  subscriber, or to an agency operated by or subject to the control of such a  rating organization, nor shall the Department's rules state that the  insurer must record or report its experience in accordance with a uniform  statistical plan which differs from that which is regularly employed and  used in the usual course of such company's business. Any  company not reporting such experience to a rating  organization or other agency designated by the Director, shall report such  experience to the Director. The Director may designate one or more rating  organizations or other agencies to assist him in gathering all such  experience and in making compilations thereof. The experience of any  company filed with the Director shall be deemed confidential and shall not  be revealed by the Director to any other company or other person, provided,  however, that the Director may make compilations of all experience,  including the experience of any such company, or of such experience and the  compilation made by the designated rating organization or other agency. All  such compilations, whether made by the Director or by any designated rating  organization or other agency, shall be made available, subject to  reasonable rules promulgated by the Director, to companies and rating  organizations.(2) Interchange of Rating Plan DataReasonable rules and plans may be promulgated by the Director for the  interchange of data necessary for the application of rating plans.(3) Consultation with Other StatesIn order to further uniform administration of rate regulatory laws, the  Director and every company and rating organization may exchange information  and experience data with insurance supervisory officials, companies and  rating organizations in other states and may consult with them with respect  to rate making and the application of rating systems.(4) Rules and RegulationsThe Director may make reasonable rules and regulations necessary to  effect the purpose of this Article.
