N.C. Gen. Stat. § 147-64.3: Legislative and management control system.

It is the intent of this Article that the State Auditor shall perform or coordinate all audit functions for State government. As appropriate, all State agencies are encouraged to establish, maintain, and use effective systems of management control. The adequacy of these control systems will be reviewed by the Auditor. The Auditor may, at his discretion, use such reviews to limit his audit activity or to suggest guidelines, make recommendations, and provide assistance where necessary within the resources available.
