N.C. Gen. Stat. § 147-69
Banks and savings and loan associations having State deposits shall furnish to the Auditor of the State, upon the Auditor's request, a statement of the moneys which have been received and paid by them on account of the treasury. The Treasurer shall keep in the Treasurer's office a full account of all moneys deposited in and drawn from all banks and savings and loan associations in which the Treasurer may deposit or cause to be deposited any of the public funds, and these accounts shall be open to the inspection of the Auditor. The Treasurer shall sign all checks, and no depository bank or savings and loan association shall be authorized to pay checks not bearing the Treasurer's official signature. The Treasurer is authorized to use a facsimile signature machine or device in affixing the Treasurer's signature to warrants, checks or any other instrument the Treasurer is required by law to sign. The Commissioner of Banks, the bank examiners, and the savings and loan examiners, when so required by the State Treasurer, shall keep the State Treasurer fully informed at all times as to the condition of all these depository banks and savings and loan associations, so as to fully protect the State from loss. The State Treasurer shall, before making deposits in any bank or savings and loan association, require ample security from the bank or savings and loan association for these deposits.
