Section 116D-12 - Variable rate demand bonds and notes(a) In fixing the details of bonds and notes, the State Treasurer may provide that the bonds and notes may: (1) Be made payable from time to time on demand or tender for purchase by the owner, if a credit facility supports the bonds or notes, unless the State Treasurer specifically determines that a credit facility is not required upon a finding and determination by the State Treasurer that the absence of a credit facility will not materially and adversely affect the financial position of the State and the marketing of the bonds or notes at a reasonable interest cost to the State.(2) Be additionally supported by a credit facility.(3) Be made subject to redemption or a mandatory tender for purchase prior to maturity.(4) Bear interest at rates that may vary from any periods of time, as may be provided in the proceedings providing for the issuance of the bonds or notes, including, without limitation, any variations as may be permitted pursuant to a par formula.(5) Be made the subject of a remarketing agreement whereby an attempt is made to remarket bonds or notes to new purchasers prior to their presentment for payment to the provider of the credit facility or to the State.(b) If the aggregate principal amount payable by the State under a credit facility is in excess of the aggregate principal amount of bonds or notes secured by the credit facility, whether as a result of the inclusion in the credit facility of a provision for the payment of interest for a limited period of time or the payment of a redemption premium, or for any other reason, then the amount of authorized but unissued bonds or notes during the term of the credit facility shall not be less than the amount of the excess, unless the payment of the excess is otherwise provided for by agreement of the State executed by the State Treasurer.N.C.
