A. Upon any liquidation of a domestic mutual insurer, its assets remaining after discharge of its indebtedness, policy obligations, repayment of contributed or borrowed surplus, if any, and expenses of administration, shall be distributed to existing persons who were its members at any time within thirty-six (36) months next preceding the date such liquidation was authorized or ordered, or date of last termination of the insurer's certificate of authority, whichever date is the earliest.
B. The distributive share of each such member shall be in the proportion that the aggregate premiums earned by the insurer on the policies of the member during the combined periods of his membership bear to the aggregate of all premiums so earned on the policies of all such members. The insurer may make a reasonable classification of its policies so held by such members and a formula based upon such classification for determining the equitable distributive share of each such member. Such classification and formula shall be subject to the approval of the Commissioner.
C. Subsections A and B above shall not apply to any mutual which, prior to July 1, 1957, has provided for any other method of liquidation through its articles and bylaws, and which have been approved by the then Insurance Commissioner.
