(1) A domestic stock insurer may increase or decrease its authorized capital stock or reclassify the same by changing the number, par value, designations, preferences or relative participating, optional or other special rights of the shares, or the qualifications, limitations, or restrictions of such rights as provided in this section. The par value of stock provided for in any amendment shall conform to the same limitations as to par value as provided for stock issued pursuant to original articles of incorporation.

  (2) If a domestic stock insurer proposes to increase, decrease, or reclassify its capital stock, it shall first present its petition to the commissioner setting forth the reasons for the increase, decrease, or reclassification. The commissioner, if satisfied that the proposed increase or decrease is for the best interests of the insurer and its policyholders, and that no reasonable objection exists, may authorize and approve the proposed plan of increase or decrease, or may direct such modification of the plan as may seem proper. After the approval of the petition by the commissioner, the increase or decrease must be approved and the articles of incorporation amended in this respect, by written consent given without a meeting or by the affirmative vote in person or by proxy at a regular or special meeting of the stockholders of not less than a majority of the capital stock of the insurer having voting power. Notice of the meeting and the purpose for which the meeting is called shall be served on each of the stockholders, either personally or by mail to the last known address of each stockholder at least 3 weeks prior to the meeting. However, if any proposed amendment would alter or change the preferences, special rights, or powers given to any 1 or more classes of stock by the articles of incorporation so as to affect that class or those classes of stock adversely or would increase or decrease the amount of the authorized stock of that class or those classes of stock adversely or would increase or decrease the par value of 1 or more classes of stock, then the holders of the stock of each class of stock so affected by the amendment shall be entitled to give written consent or vote as a class upon the amendment regardless of whether the terms of the articles of incorporation entitle the class to vote or not, and the affirmative action of a majority in interest of each class of stock so affected by the amendment shall be necessary for its adoption in addition to the affirmative action of the majority of all stock entitled to vote on an amendment as is required by law for its adoption. Separate action of any class of stock proposed to be increased or decreased shall not be required if the provisions of the articles of incorporation or amendment to the articles creating the class shall have authorized the increase or decrease without separate action.

  (3) An amendment to the articles of incorporation shall not become effective until finally approved by the commissioner and until submitted to the attorney general and certified by him or her as not to be in conflict with the constitution or laws of this state. Amendments to the articles of incorporation shall be filed in duplicate with the commissioner, 1 copy to be retained by the commissioner and 1 copy to be returned to the insurer with a certified copy of the certificate of the approval of the commissioner attached.
