Section 611.28 - Changes in business plan(1) DEVELOPMENT STAGE. Within 5 years after the initial issuance of a certificate of authority no substantial change, alteration or amendment may be made in the business plan and the insurer may not substantially deviate from it unless notice of the proposed change is filed with the commissioner 30 days in advance of the proposed effective date. The commissioner may defer the effective date for an additional period not exceeding 30 days by written notice to the corporation before expiration of the initial 30-day period. The commissioner may, within the 30-day period or its extension, prohibit the proposed action if it is contrary to law or to the interests of insureds, creditors or the public in this state.(2) CONTINUING CONTROL. The commissioner may by rule or order specify portions of the business plan to which the requirement of sub. (1) shall apply even after the initial 5-year period, if he or she finds after a hearing that it is required to protect the interests of insureds, creditors or the public in this state.1971 c. 260; 1979 c. 102 s. 236 (5); 1991 a. 316.
