(1) Shares of a bank may, but need not be, represented by certificates. Unless this title expressly provides otherwise, the rights and obligations of shareholders are identical whether or not their shares are represented by certificates. At a minimum, each share certificate must state the information required to be stated and must be signed as provided in RCW 23B.06.250
(2) Unless the articles of incorporation or bylaws provide otherwise, the board of directors of a bank may authorize the issue of some or all of the shares of any or all of its classes or series without certificates. The authorization does not affect shares already represented by certificates until they are surrendered to the bank.
(3) Within a reasonable time after the issue or transfer of shares without certificates, the bank shall send the shareholder a written statement of the information required to be stated on certificates under subsection (1) of this section.
