Every insurer shall file annually on, or before, July 1, with the rating organization of which it is a member or subscriber, or with such other common agency representing a group of insurers as the department may approve, and with the department a statistical report showing its premiums and its losses on all kinds of insurance to which this article is applicable, together with such other information as the department may deem necessary for the proper determination of the reasonableness and adequacy of rates. Such statistical report filed with the rating organization may be consolidated and filed by such common agency. Such data shall be kept and reports made in such manner and on such forms as may be prescribed by the commissioner. All such annual filings with the department shall be kept under lock and key, and any official or employee of the department who shall divulge the contents or permit the examination thereof, except for the purpose of properly administering the provisions of this article or upon the order of court, shall be guilty of a misdemeanor and shall be subject to a fine of not more than $50.00 and shall thereafter be ineligible to be an employee or agent of said department. Reasonable rules and plans may be promulgated by the commissioner, after consultation with all insurers and rating organizations affected thereby, for the interchange of loss experience necessary for the application of rating plans. In order to further uniform administration of rating laws, the commissioner and every insurer and rating organization may exchange information and experience data with insurance supervisory officials, insurers, and rating organizations in other states and may consult and cooperate with them with respect to rate-making and the application of rating systems. The commissioner may make reasonable rules and regulations necessary to effect the purposes of this article.
