(a) In addition to the minimum capital required by this chapter for a capital stock association to commence business, the subscribers to the capital stock of the association shall pay an additional amount for their stock equal to not less than fifty percent (50%) of the par or stated value of the stock subscribed, which additional amount shall be credited to the paid-in surplus account and may be used for organization and operating expenses, including interest to the holders of deposit accounts. The minimum capital and surplus may be used for the reserves required by this chapter and as permitted by the commissioner.
