The interest, income and profits, if any, earned or realized on any such investment may also be applied to the payment of the outstanding bonds or notes to be so refunded. After the terms of the escrow have been fully satisfied and carried out, any balance of such proceeds and interest, income and profits, if any, earned or realized on the investments thereof may be returned to the Authority for use by it in any lawful manner.(d) The portion of the proceeds of any such bonds or notes issued for the additional purpose of paying all or any part of the cost of constructing and acquiring additions, improvements, extensions or enlargements of a project may be invested and reinvested in direct obligations of the United States of America, or in certificates of deposit or time deposits secured by direct obligations of the United States of America, or in any other obligation or security as may be determined by the Authority maturing not later than the time or times when such proceeds will be needed for the purpose of paying all or any part of such cost. The interest, income and profits, if any, earned or realized on such investment may be applied to the payment of all or any part of such cost or may be used by the Authority in any lawful manner.(e) All such bonds or notes shall be subject to this chapter in the same manner and to the same extent as other bonds or notes issued pursuant to this chapter.59 Del.
