The Governor and State Treasurer, acting jointly may whenever in their opinion there are funds in the state treasury in excess of the amount required to meet the current needs and demands of the Commonwealth, invest the excess funds in securities that are legal investments under the laws of the Commonwealth for public funds. The funds shall be invested in such of said securities as, in their judgment, will be readily convertible into money. Notwithstanding the provisions of § 2.2-1821 or any other provision relating to the withdrawal of state moneys in a state depository, withdrawals and transfers of state moneys to be so invested may be made by state depositories pursuant to oral including telephonic or electronic instructions of the State Treasurer or his duly authorized deputies.

Payment of state moneys pursuant to this procedure shall be valid against the Commonwealth.
