(a) At a savings bank's closing date, the savings bank may use all or part of a surplus account, whether earned or paid in, or expense fund contributions on its books to:
(1) meet expenses of operating the savings bank for the period just closed;
(2) make required transfers to loss reserves; or
(3) pay or credit earnings on deposit accounts.
(b) Paid-in surplus may be used instead of earnings to pay organizational and operating expenses and earnings on deposit accounts and to meet any loss reserve requirements.
