At any annual meeting or any special meeting called for the purpose, any association may, by majority vote of its members or stockholders who are entitled to vote, resolve to liquidate and dissolve the association. Before the resolution takes effect, a copy certified by the president and the secretary of the association, together with an itemized statement of its assets and liabilities sworn to by a majority of its board of directors, shall be filed with, and approved by, the supervisor. When the supervisor has approved the resolution, it is thereafter unlawful for the association to accept any additional savings accounts or additions to savings accounts or to make any additional loans, but all its income and receipts in excess of actual expenses of liquidation of the association shall be applied to the discharge of its liabilities. The board of directors of the association, under the supervision of the supervisor and in accordance with a plan of liquidation approved by him, shall thereupon proceed to liquidate the affairs of the association and reduce its assets to cash for the purpose of paying, satisfying and discharging all existing liabilities and obligations of the association, including the withdrawal value of all savings accounts, the balance remaining, if any, to be distributed pro rata among the savings account holders of record on the date of adoption by the association of the resolution to liquidate; but if the association has outstanding permanent capital stock, any balance remaining after all liabilities and obligations have been fully paid and satisfied, including the withdrawal value of all savings accounts, shall be distributed among the holders of the stock in proportion to their stockholding. All expenses incurred by the supervisor or any of his representatives during the course of any liquidation shall be paid from the assets of the association. Upon completion of liquidation, the board of directors shall file with the supervisor a final report and accounting of the liquidation. Approval of the report by the supervisor is a complete and final discharge of the board of directors and each member in connection with the liquidation of the association.
