Texas Government Code - GOV'T § 802.203. Fiduciary Responsibility

(a) In making and supervising investments of the reserve fund of a public retirement system, an investment manager or the governing body shall discharge its duties solely in the interest of the participants and beneficiaries:

(b) In choosing and contracting for professional investment management services and in continuing the use of an investment manager, the governing body must act prudently and in the interest of the participants and beneficiaries of the public retirement system.

(c) A trustee is not liable for the acts or omissions of an investment manager appointed under Section 802.204, nor is a trustee obligated to invest or otherwise manage any asset of the system subject to management by the investment manager.

(d) An investment manager appointed under Section 802.204 shall acknowledge in writing the manager's fiduciary responsibilities to the fund the manager is appointed to serve.

(e) The investment standards provided by Subsection (a) and the policies, requirements, and restrictions adopted under Section 802.204(c) are the only standards, policies, or requirements for, or restrictions on, the investment of funds of a public retirement system by an investment manager or by a governing body during a 90-day interim between professional investment management services. Any other standard, policy, requirement, or restriction provided by law is suspended and not applicable during a time, and for 90 days after a time, in which an investment manager is responsible for investment of a reserve fund. If an investment manager has not begun managing investments of a reserve fund before the 91st day after the date of termination of the services of a previous investment manager, the standards, policies, requirements, and restrictions otherwise provided by law are applicable until the date professional investment management services are resumed.
