After reorganization or conversion pursuant to the provisions of this act, each capital stock association shall maintain an adequate capital structure appropriate for the conduct of its business and the protection of its depositors. The adequacy of the capital of a capital stock association shall be determined by the commissioner after a valuation of the character of management, the liquidity of assets, history of earnings and the retention thereof, the potential volatility of the account or deposit structure and with due regard to the association's capacity to furnish the broadest services to the public. The reserves required by this act and the capital of a capital stock association resulting from the conversion of a mutual association shall not be less than 5% of its savings accounts or deposits.
