Tennessee Code Title 9. Public Finances § 9-21-504

(a) Bond anticipation notes issued in anticipation of bonds secured by the full faith and credit of the local government shall be secured by a pledge of the taxing power of the local government, as to all taxable property in the local government or a portion of the local government, if applicable, which shall be subject to taxation for the payment of the bonds, the issuance of which is anticipated by such notes, and may, at the option of the local government, be additionally secured by the same revenues which will secure the bonds, the issuance of which is anticipated by such notes and identified in the initial resolution authorizing such bonds. When the bond anticipation notes are so issued and sold, they shall be direct obligations of the local government, the payment of which shall be made according to the tenor and effect thereof. The governing body of the local government is hereby authorized to levy and provide for the collection of a special tax over and above all other taxes authorized or limited by law to be imposed and levied on all the taxable property in the local government or a portion of the local government, if applicable, to create a sinking fund to retire the notes with interest as they fall due.

(b) Bond anticipation notes issued in anticipation of the issuance of bonds secured by and payable solely from revenues of a public works project may be secured by the revenues from the public works project.

(c) When bonds shall have been issued and sold for a public works project, a sufficient amount of the proceeds shall be applied to the payment at their maturity or redemption of any bond anticipation notes issued for such public works project then outstanding. Nothing in this chapter shall prohibit the retirement of bond anticipation notes from other local government funds available and authorized for such purpose.
