(A) No stock state bank shall lend money on the security of shares of its own stock or accept shares of its own stock in satisfaction of a debt, unless necessary to prevent loss on a debt previously contracted in good faith.

(B) A stock state bank that accepts shares of its own stock as allowed by division (A) of this section shall retire or dispose of the shares at the time and in the manner required by the superintendent of financial institutions.

(C) For purposes of this section, the superintendent may determine that stock of a person that controls a stock state bank, if the stock is not readily marketable, is the functional equivalent of stock of the bank and, therefore, subject to divisions (A) and (B) of this section.
