(1) The converting insurance company may propose to acquire, or to merge or consolidate with, one or more domestic or foreign insurers, or both, as part of a mutual holding company plan under s. 644.07. The commissioner shall approve the acquisition, merger or consolidation as part of the mutual holding company plan and shall approve the continued corporate existence of any domestic insurer that is a party to the plan under this section as a subsidiary of the mutual holding company or any intermediate stock holding company, if any of the following applies:

(a) In the case of a domestic stock corporation, no grounds for disapproval exist under s. 611.72 (3) (am).

(b) In the case of a domestic mutual, no grounds for disapproval exist under s. 611.73 (3) (a) and the domestic mutual has complied with s. 644.07 (2) to (8). The converting insurance company and any domestic mutual that the converting insurance company proposes to acquire, or merge or consolidate with, may adopt one plan. The commissioner may combine the hearings required under s. 644.07 (6) for the converting insurance company and any domestic mutual that is the subject of the acquisition by, or merger or consolidation with, the converting insurance company. Section 644.07 (9), (10) (b) to (f), and (11) applies to a domestic mutual acquired by, merged into, or consolidated with a converting insurance company under this section.

(2) Any foreign insurer acquired under a plan under this section may remain a foreign company after such acquisition and may be admitted to do business in this state if it meets the applicable requirements of ch. 618.
