Member’s share of assets on voluntary dissolution.

(1) Upon any voluntary dissolution of a domestic mutual insurance holding company, its assets remaining after discharge of its indebtedness, if any, and expenses of administration, shall be distributed to existing persons who were its members at any time within the 3-year period preceding the date such liquidation was authorized or ordered, or date of last termination of the insurer’s certificate of authority, whichever date is earlier; except, if the office has reason to believe that those in charge of the management of the mutual insurance holding company have caused or encouraged the reduction of the number of members of the insurer in anticipation of liquidation and for the purpose of reducing thereby the number of persons who may be entitled to share in distribution of the insurer’s assets, the office may enlarge the 3-year qualification period by such additional time as the office may deem to be reasonable.

(2) The distributive share of each such member shall be determined:

(a) For domestic mutual insurance holding companies owning solely life and health insurance subsidiaries, by a formula based upon such reasonable classifications of members as the department may approve.

(b) For all other domestic insurance holding companies, based upon the ratio that the total amount of paid premiums paid by such member for policies of insurance during the 3-year period or part of such period specified in subsection (1) during which such recipient was a member bears to the total amount of paid premiums paid by all members entitled to receive a distributive share as a result of such dissolution during such entire 3-year period and upon such reasonable classifications of members as the department may approve, unless the domestic mutual insurance holding company submits another fair formula that is approved by the department.
