Tennessee Code Title 9. Public Finances § 9-4-608

(a) The state funding board shall determine whether a need exists for a longer-term investment fund for funds in the custody of the state treasurer. Upon determining that such a need exists, the state funding board may, by resolution duly adopted, create an intermediate-term investment fund as an additional investment vehicle for money in the custody of any department or agency of the state which is required by court order, contract, state or federal law or federal regulation to receive interest on invested funds. The funding board shall establish the terms of participation in the fund, and shall set the minimum and maximum amounts which may be invested in the fund by each participant. The investment fund shall be administered by the state treasurer within the guidelines established by the funding board.

(b) The authorized instruments for investment in the intermediate-term investment fund shall be those instruments contained in § 9-4-602, as well as the pooled investment fund set forth in § 9-4-603.

(c) Any department or agency of the state which is required by court order, contract, state or federal law or federal regulation to receive interest on invested funds may apply with the state treasurer to participate in the fund. Upon approval of any such application and upon investment of cash in the fund, the respective department or agency shall be deemed a participant in the fund. The general fund of the state may also participate in the fund. A participant may invest its cash for any length of time in the fund; provided, that the funding board may establish restrictions for withdrawal and/or penalties for early withdrawal.

(d) All securities purchased shall belong jointly to the participants in the fund and the participants will share capital gains, income, and losses pro rata.

(e) The state treasurer shall keep a separate account, designated by name and number of each participant. Individual transactions and totals of all investments belonging to each participant shall be recorded in the accounts.

(f) The state treasurer shall report monthly to every participant having a beneficial interest in the intermediate-term investment fund. The report shall show the changes in investments made during the preceding month.

(g) The state treasurer shall establish a revolving account, under the state treasurer's custody, to defray administrative costs of the investment fund. The state treasurer may deduct from each participant's pro rata earnings through the fund, a reasonable charge for administering the fund. In the event that the state treasurer does deduct an administrative fee, it shall be deposited and expended through the revolving account.

(h) The county legislative body shall determine whether a need exists for a longer-term investment for funds in the custody of the county trustee. Upon determining that such a need exists, the county legislative body may, by resolution duly adopted, authorize the county trustee to invest county funds in the state intermediate-term investment fund, notwithstanding § 5-8-301. The resolution shall contain a disclosure statement as the treasurer shall periodically require. County investments in the state intermediate-term investment fund shall be administered by the county trustee within the guidelines established.

(i) Notwithstanding § 5-8-301, any entity that is eligible to participate in the pooled investment fund codified in § 9-4-603 may participate in the state intermediate-term investment fund.

(j) Local governments may invest in the intermediate-term investment fund by having the local government's legislative body, council, commission or other authorizing individual or authorizing governing body submit a duly adopted resolution to the state treasurer demonstrating its authority to participate, along with any other documents required by the state treasurer. The resolution shall contain a disclosure statement as the state treasurer shall periodically require.

(k) As the administrator of the intermediate-term investment fund, the state treasurer is authorized to receive, invest and distribute a participant's funds by means of an electronic transfer or other reasonable methods. The state funding board may establish limits, conditions or restrictions on the acceptance of moneys into the fund and the withdrawal of moneys from the fund.
