A newly chartered state savings bank must commence business within one year after corporate existence begins. A state savings bank that does not commence business within this time, forfeits its corporate existence, unless the board, before the expiration of the one-year period, approves an extension of the time within which the state savings bank may commence business, upon a written request stating the reasons for the request. Upon forfeiture, the articles of incorporation expire and action taken in connection with the incorporation and chartering of the state savings bank, with the exception of fees paid to the board, becomes null and void. The board shall determine if a state savings bank has failed to commence business within one year, without extension as provided in this section, and shall notify the Secretary of State and the register of deeds in the county in which the state savings bank is located that the articles of incorporation have expired. If the board finds that the state savings bank has in good faith complied with all the requirements of law and all conditions imposed, and that the state savings bank’s deposit accounts are properly insured, it shall promptly issue a certificate of authorization to transact a general state savings bank business.
