N.C. Gen. Stat. § 159-33
Each officer having custody of any funds of any local government or public authority shall report to the secretary of the Local Government Commission on January 1 and July 1 of each year (or such other dates as he may prescribe) the amounts of funds then in his custody, the amounts of deposits of such funds in depositories, and a list of all investment securities and time deposits held by the local government or public authority. In like manner, each bank or trust company acting as the official depository of any unit of local government or public authority may be required to report to the secretary a description of the surety bonds or investment securities securing such public deposits. If the secretary finds at any time that any funds of any unit or authority are not properly deposited or secured, or are invested in securities not eligible for investment, he shall notify the officer or depository in charge of the funds of the failure to comply with law or applicable regulations of the Commission. Upon such notification, the officer or depository shall comply with the law or regulations within 30 days, except as to the sale of securities not eligible for investment which shall be sold within nine months at a price to be approved by the secretary. The Commission may extend the time for sale of ineligible securities, but no one extension may cover a period of more than one year.
