Va. Code Ann. § 5.1-2.10

All moneys received pursuant to the authority of this chapter, whether as proceeds from the sale of bonds or as revenues, shall be deemed to be trust funds to be held and applied solely as provided in this chapter. The resolution authorizing the bonds of any issue or the trust agreement securing such bonds shall provide that any officer with whom, or any bank or trust company with which, such moneys shall be deposited shall act as trustee of such moneys and shall hold and apply the same for the purposes hereof, subject to such regulations as this chapter and such resolution or trust agreement may provide. In the case of revenues or the proceeds from the sale of revenue bonds, the trustee may invest and reinvest such funds in securities that are legal investments under the laws of the Commonwealth for funds held by fiduciaries pending their need for the construction of the projects. In the case of the proceeds of the sale of refunding bonds, the trustee may invest and reinvest such funds in direct obligations of, or obligations the principal of and the interest on which are guaranteed by, the United States of America. Such money and the interest, income and profits, if any, earned on such investment shall be available for the payment of all or any part of the principal, interest and redemption premium, if any, of the bonds being refunded. The proceeds of the sale of refunding bonds shall be so invested and applied as to ensure that the principal, interest and redemption premium, if any, on the bonds being refunded shall be paid in full on their respective maturity, redemption or interest payment dates. After the terms of the trust have been fully satisfied, any balance of such proceeds, interest, income and profits, if any, realized on the investments thereof may be returned to the Board for use by it in any lawful manner.
