Whenever the commissioner has reason to believe that the capital of any capital stock Connecticut bank is impaired but the impairment is not sufficient to require other action for the protection of the public, the commissioner may notify such bank in writing to make good any impairment of capital within a time to be fixed by the commissioner. For purposes of this section, the capital of a bank is impaired if the equity capital of the bank is less than zero. At the end of such period, the commissioner shall make, or cause to be made, an examination of such bank, and, upon finding at any time thereafter an impairment of capital, the commissioner may deliver to such bank a written order to discontinue receiving moneys for deposit or for certificates of indebtedness and paying depositors, clients or other creditors. The commissioner may thereupon bring an action in the superior court for the judicial district of Hartford or the judicial district in which the main office of such bank is located for its dissolution and for the appointment of a receiver to take charge of its affairs. Such written order of the commissioner, until vacated by an order of the court, shall have the effect of a temporary injunction restraining such bank, its directors, officers and employees, from receiving moneys for deposit or for certificates of indebtedness and paying depositors, clients or other creditors. Nothing in this section shall require the commissioner to take any action for the restoration of any impairment of capital or for the appointment of a receiver if, in the commissioner’s opinion, the remaining capital of any such bank is sufficient to protect the depositors, clients and other creditors thereof from loss.
