Sec. 5246. The board of directors of a domestic insurer shall select a president, a secretary, and a treasurer, or such equivalent officers as may be designated in its articles or bylaws, and may select 1 or more vice-presidents, assistant secretaries and assistant treasurers. Any 2 of the above offices except those of president and vice-president may, unless otherwise provided by the bylaws, be held by the same person but no officer shall execute, acknowledge, or verify an instrument in more than 1 capacity. The board may also appoint such other officers and agents as they may deem necessary for the transaction of the business of the corporation. All officers and agents shall respectively have such authority and perform such duties in the management of the property and affairs of the corporation, as may be delegated by the board of directors. Any officer or agent may be removed by the board of directors whenever in their judgment the business interests of the corporation will be served thereby. The board of directors may secure the fidelity of any or all of such officers by bond or otherwise. Unless otherwise provided in the articles or bylaws, the board of directors shall have power to fill any vacancies in any offices occurring from whatever reason.
