Any company organized to transact the business of life insurance or insurance against accident or sickness under any laws of this state in force prior to August 10, 1917, may reorganize under this code, and have the benefit of all its provisions, by a vote of the stockholders, or, if it be a mutual company, then by a vote of the members called for that purpose, in pursuance of its present articles, on entering into new articles of incorporation, signed by its charter officers, setting forth the particulars required under this code and filing a copy of such articles with the commissioner and the proper county clerk, after such a certificate of the attorney general has been obtained as is required when the articles are amended; and such company, in so reorganizing, shall be at liberty to make any change in its mode of doing business, not inconsistent with the provisions of this code, and to increase its capital stock, or to retire any guaranteed capital stock, as the stockholders or members may deem proper; but in so reorganizing they shall be subject to all the provisions of this code in regard to the deposit of securities, and to all its other provisions in the same manner and to the same extent as if such company had not previously had a corporate existence.
