N.C. Gen. Stat. § 159-37: Reports on status of sinking funds.

Each unit or public authority maintaining any sinking fund shall transmit to the secretary upon his request financial reports on the status of the fund and the means by which moneys are obtained for deposit therein. The secretary shall determine from this information whether the sinking funds are being properly maintained, and if he shall find that they are not, he shall order the unit to take such action as may be necessary to maintain the funds in accordance with law.
