Membership in a State association operating pursuant to the share plan shall be evidenced by a share certificate, account book, or, in lieu thereof any other evidence of the account which may be approved by the commissioner, provided, however, the membership of a borrowing member may be evidenced only by a membership certificate.
Such State associations may issue the following types of shares, all of which shall be common shares:
(1) Installment shares, which shall be issued in connection with accounts upon which payments are made periodically in regular amounts as required by the by-laws. The by-laws shall specify the maturity value of such accounts. All such accounts shall have the same maturity value, but the by-laws may be amended to provide that accounts thereafter issued shall have a different maturity value from those theretofore issued. Upon the maturity of an installment share account so much of its participation value as remains after payment of any obligation for which it may have been pledged, shall be disposed of in one of the following ways:
(a) The State association may pay the same to the member under the same terms and conditions which apply to the payment of withdrawals.(b) The State association may transfer the same to any other type of account in said State association to the credit of the member, giving him immediate written notice thereof, personally or by mail.(c) The member may withdraw the same in accordance with the same terms and conditions which apply to other withdrawals.(2) Savings shares, which shall be issued in connection with accounts upon which payments may be made at the option of the member.(3) Income shares, which shall be issued in connection with accounts requiring the investment of fixed amounts in units of $100.00 or multiples thereof, upon which dividends are paid in cash.
