Tennessee Code Title 9. Public Finances § 9-4-404

(a) The state treasurer shall evaluate the market value of required collateral monthly, and more frequently if market conditions require.

(b) Any state depository whose collateral has a market value less than one hundred five percent (105%) of the value of its state deposits, less so much of such amount as is protected by the federal deposit insurance corporation, shall provide additional collateral at the request of the state treasurer.

(c) If within two (2) working days such additional collateral is not provided, the state treasurer shall submit to the commissioners of financial institutions and of finance and administration a written summary of the results of the market valuation of collateral for that depository, together with a summary of the deposits secured by the collateral and take such action as a majority of these three (3) officials, based upon information received pursuant to § 9-4-402, deems appropriate. Such action may include withdrawal of part or all of the state deposit in that depository without penalty or forfeiture of interest.

(d) The state treasurer, county trustee or other public official charged with the deposit of public funds may contract for the evaluation of the market value of required collateral. Such contract may be with any person, including a financial institution or trustee custodian; provided, that such contract may not be with the depository pledging the collateral to be valued.
