The savings liability of an association is not limited, but shall consist only of the aggregate amount of savings accounts of its members or savings account holders, plus earnings credited to such accounts, less redemption and withdrawal payments. Except as limited by the board of directors from time to time, a member or savings account holder may make additions to his savings accounts in such amounts and at such times as he may elect. The members or savings account holders of an association shall not be responsible for any losses which its savings liability shall not be sufficient to satisfy, and savings accounts shall not be subject to assessment. Earnings shall be declared in accordance with the provisions of this chapter. Except as provided in Section 81-12-153, no association shall prefer one (1) of its savings accounts over any other savings account as to the right to participate in earnings. No preference between savings account members or savings account holders shall be created with respect to the distribution of assets upon voluntary or involuntary liquidation, dissolution or winding up of an association. No association shall issue, sell, negotiate or advertise any type of savings account or debt security, except as authorized by this chapter, nor shall it contract with respect to any savings account or other account in a manner inconsistent with the provisions of this chapter.
