Notwithstanding any restriction in its articles of incorporation limiting the number, kinds and classes of accounts that it may offer, a state savings institution may offer such accounts, including checking accounts, time deposit accounts, and savings accounts, as its board of directors may authorize from time to time. A state savings institution may pay interest on such accounts at such rates and under such terms and conditions as its board of directors may direct from time to time, subject to any restrictions and limitations imposed by state or federal law on the payment of interest.
