Whenever a bank’s surplus at the close of any period for which it shall have determined its net profits pursuant to section 50 is not equal to fifty per centum of its capital stock, the bank shall promptly thereafter transfer to surplus not less than ten per centum of its net profits for such period, determined as provided in section 50. Nothing in this section shall require a transfer to surplus in excess of an amount sufficient to increase the bank’s surplus to fifty per centum of its capital stock.
