625.21 Delaying effect of rates.
(1) Rule instituting delayed effect. If the commissioner finds that competition is not an effective regulator of the rates charged or that a substantial number of companies are competing irresponsibly through the rates charged, or that there are widespread violations of this chapter, in any kind or line of insurance or subdivision thereof or in any rating class or rating territory, he or she may promulgate a rule requiring that in the kind or line of insurance or subdivision thereof or rating class or rating territory comprehended by the finding any subsequent changes in the rates or supplementary rate information be filed with the commissioner at least 15 days before they become effective. The commissioner may extend the waiting period for not to exceed 15 additional days by written notice to the filer before the first 15-day period expires.
(2) Supporting data. By rule, the commissioner may require the filing of supporting data as to any or all kinds or lines of insurance or subdivisions thereof or classes of risks or combinations thereof as the commissioner deems necessary for the proper functioning of the rate monitoring and regulating process. The supporting data shall include:
(a) The experience and judgment of the filer, and, to the extent it wishes or the commissioner requires, of other insurers or rate service organizations;
(b) Its interpretation of any statistical data relied upon;
(c) Descriptions of the actuarial and statistical methods employed in setting the rates; and
(d) Any other relevant matters required by the commissioner.
(3) Expiration of rule. A rule promulgated under sub. (1) shall expire no more than one year after issue. The commissioner may renew it after a hearing and appropriate findings under sub. (1).
(4) Supporting information. Whenever a filing is not accompanied by the information the commissioner requires under sub. (2), the commissioner may so inform the insurer and the filing shall be deemed to be made when the information is furnished.
