(1) With the approval of the banking board, a state bank may liquidate and dissolve. The banking board shall grant such approval if it appears that the proposal to liquidate and dissolve has been approved by a vote of two-thirds of the outstanding voting stock at a meeting called for that purpose and that the capital of the state bank is adequate and such state bank has sufficient liquid assets to pay off depositors and creditors immediately.

(2) (a) Upon approval by the banking board, the bank shall forthwith cease to do business, shall have only the powers necessary to effect an orderly liquidation, and shall proceed to pay its depositors and creditors and to wind up its affairs.

(b) Within thirty days after the approval, a notice of liquidation shall be sent by mail to each depositor, creditor, person interested in funds held as a fiduciary, lessee of a safe deposit box, and bailor of property at the address of such person as shown on the books of the bank. The notice shall be posted conspicuously on the premises of the bank and shall be given such publication as the banking board may require. The bank shall send with each notice a statement of the amount shown on the books to be the claim of the depositor or creditor. The notice shall demand that property held by the bank as bailee or in a safe deposit box be withdrawn bythe person entitled thereto and that claims of depositors and creditors, if the amount claimed differs from that stated in the notice to be due, be filed with the bank before a specified date not earlier than sixty days thereafter, in accordance with the procedure prescribed in the notice.

(c) As soon after approval as may be practicable, the state bank shall resign all fiduciary positions and take such action as may be necessary to settle its fiduciary accounts.

(d) Safe deposit boxes, the contents of which have not been removed within thirty days after demand, shall be opened. Sealed packages containing the contents of such box, with a certificate of inventory of contents, together with any other unclaimed property held by the bank as bailee and certified inventories thereof shall be transferred to the banking board, which shall retain them for six years unless sooner claimed by the person entitled to them. After six years the banking board shall sell or otherwise appropriately dispose of the property. The proceeds of any sale shall be transferred to the state treasurer as abandoned funds.

(e) The approval of an application for liquidation shall not impair any right of a depositor or creditor to payment in full, and all lawful claims of creditors and depositors shall promptly be paid. The unearned portion of the rental of a safe deposit box shall be returned to the lessee.

(f) Any assets remaining after the discharge of all obligations shall be distributed to the stockholders in accordance with their respective interests. No such distribution shall be made before all claims of depositors and creditors have been paid or, in the case of any disputed claim, the bank has transmitted to the banking board a sum adequate to meet any liability that may be judicially determined and any funds payable to a depositor or creditor and unclaimed have been transmitted to the banking board.

(3) Any unclaimed distribution to a stockholder or depositor shall be held until ninety days after the final distribution and then transmitted to the banking board. Such unclaimed funds shall be held by the banking board for six years and, unless sooner claimed by the person entitled thereto, shall be transferred to the treasury of the county in which the bank is located. The county treasurer and his successors shall hold such money in trust for a period of six years, unless the same shall be sooner paid out to the beneficial owner thereof or a suit is instituted to recover such money or a portion thereof. Any money remaining in said fund six years after the same is paid into the treasury of the county, for the recovery of which no action is pending, shall be transferred to the general fund of the county, and all rights of the former beneficial owners therein to recover the same shall be forever barred.

(4) If the banking board finds that the assets will be insufficient for the full discharge of all obligations, or that completion of the liquidation has been unduly delayed, it may take possession and complete the liquidation in the manner provided in this code for involuntary liquidations.

(5) The banking board may require reports of the progress of liquidation. If it is satisfied that the liquidation has been properly completed, it shall cancel the charter and enter an order of dissolution.
