Dividends declared; conditions.

The board of directors of any bank may declare dividends on its capital stock but only under the following conditions: (1) All bad debts required to be charged off by either the board of directors or the department shall first have been charged off. All debts due any bank on which interest is past due and unpaid for a period of six months, unless such debts are well secured or in the process of collection, shall be considered bad debts within the meaning of this section; and (2) Twenty percent of the net profits accumulated since the preceding dividend shall first have been carried to the surplus fund unless such surplus fund equals or exceeds the amount of the paid-up capital stock.
