Okla. Stat. tit. 69, § 69-1237: Deposit and investment of monies

Any monies credited to, or appropriated to, the Highway Advance

Right-of-Way Acquisition and Management Fund, shall be deposited in

such fund in the State Treasury. Any monies in such fund shall be

invested by the State Treasurer upon direction of the State Highway

Director in direct obligations of the United States of America or in

certificates of deposits from banks in the State of Oklahoma

acceptable as depositories by the State Treasurer, when such

certificates of deposits are secured by acceptable collateral and

yield as much, or more, than direct obligations of the United States

of America. Any such investment shall mature in time to enable the

State of Oklahoma to issue warrants against the fund for payment of

indebtedness incurred for the purpose for which the Highway Advance

Right-of-Way Acquisition and Management Fund is created. Any

interest earned on such investments shall likewise be deposited in

said fund.
