N.D. Cent. Code § 26.1-12.1-02
A domestic mutual insurance company, upon approval of the commissioner, may reorganize by forming an insurance holding company based upon a mutual plan and continuing the corporate existence of the reorganizing insurer as a stock insurance company. The commissioner, if satisfied the reorganization meets the standards set forth in section 26.1-12.1-06, may approve the proposed plan of reorganization or may require as a condition of approval the modification of the proposed plan of reorganization as the commissioner finds necessary for the plan to meet the standards of section 26.1-12.1-06. The commissioner shall retain jurisdiction over the mutual insurance holding company and the reorganized insurer according to this section and chapter 26.1-10 to assure that policyholders' and members' interests are protected.
All of the initial shares of the capital stock of the reorganized insurer must be issued to the mutual insurance holding company or to an intermediate stock holding company that is wholly owned by the mutual insurance holding company. The membership interests of the policyholders of the reorganized insurer must be converted into membership interests in the mutual insurance holding company. Policyholders of the reorganizing insurance company must become members of the mutual insurance holding company in accordance with the articles of incorporation and bylaws of the mutual insurance holding company and the articles of incorporation and bylaws of the reorganized insurance company as approved by the commissioner. The mutual insurance holding company, directly or indirectly through an intermediate stock holding company, must control at all times a majority of the voting shares of the capital stock of the reorganized insurance company but this does not prohibit any future demutualization or other conversion.
