Tennessee Code Title 9. Public Finances § 9-4-408

(a) In lieu of the actual deposit of eligible collateral under § 9-4-407, the state treasurer is authorized, at the state treasurer's option, to accept trust receipts.

(b) Trust receipts shall be issued by trustee custodians in a form acceptable to the state treasurer following the deposit of eligible collateral with the trustee custodian by a state depository.

(c) Eligible collateral deposited with a trustee custodian shall be subject in all respects to the claims and rights of the state to the same extent as though such collateral had been physically deposited with the state treasurer under § 9-4-407.

(d) Each trust receipt shall be nonnegotiable and irrevocable and shall continue in full force and effect until surrendered by the issuing trustee custodian with the release of the state treasurer endorsed thereon over the state treasurer's signature or as otherwise released pursuant to subsection (g) or (h).

(e) The state treasurer may present the trust receipt at any time to the issuing trustee custodian and upon delivery thereof shall be entitled to receive any and all collateral represented thereby from the trustee custodian, and such collateral shall thereafter be held by the state treasurer as if deposited with the state treasurer by the state depository as collateral, without further liability on the part of the trustee custodian.

(f) Following delivery of the collateral to the state treasurer, the state treasurer is permitted to register such collateral in the name of the state and to hold it on behalf of the state depository.

(g) The state treasurer is authorized to establish alternative procedures for the deposit and release of eligible collateral held on the state treasurer's behalf by trustee custodians pursuant to this chapter.

(h) A county or city official charged with the deposit of public funds is authorized to contract for alternative procedures for the deposit and release of eligible collateral held on the behalf of the county or city by a trustee custodian pursuant to this chapter. The alternative procedure established may be the procedure adopted by the state treasurer in subsection (g), or must provide for a release of collateral only upon the authorization of the county or city official or a person authorized by law to act on behalf of the official. The official's authorization shall be given in writing and delivered, sent or transmitted to the trustee in any reasonable manner, including, without limitation, by means of telephonic facsimile transmission.
