35-457.  Sale of bonds;  bids;  forfeiture of deposit;  definitions A. Any or all of the bonds may be sold at public sale or through an online bidding process in a manner prescribed by the governing body or board that includes the following:  1. If sold by public sale before the sale of any bonds the governing body or board shall meet and enter on its record an order directing the sale of the bonds and the date and hour of the sale,  and cause a copy of the order to be published at least once a week for two successive weeks in cities having a population of fifteen thousand or more persons,  and once a week for four successive weeks in all other political subdivisions before the sale in one or more designated daily or weekly newspapers,  together with a notice that sealed proposals will be received for purchase of the bonds on the date and hour named in the order. 2. If sold through an online bidding process,  bids for the bonds that are entered into the system may be concealed until a specified time or disclosed in the online bidding process,  may be subject to improvement in favor of the political subdivision before a specified time and may be for an entire issue of bonds or specified maturities according to the manner,  terms and notice provisions ordered by the governing body. B. If the bonds are sold by public sale or through an online bidding process,  all proposals shall be received on the date and hour or in the manner stated in the order and the governing body or board shall award the bonds to the highest and most responsible bidder. The successful bidder shall provide a bid guarantee for not less than two percent of the total par value of the bonds within twenty-four hours after the date and time the bid is awarded. The bid guarantee may be in the form of a certified check or a bond issued by a surety company licensed by the department of insurance and financial institutions to do business in this state. The governing body or board may reject any and all bids. If the successful bidder does not carry out the terms of the proposal to purchase the bonds,  the bid guarantee shall be forfeited as stipulated and liquidated damages. C. Notwithstanding any other provision of this section,  bonds may be sold by negotiated sale on terms the governing body deems to be the best then available and may bear interest payable at such times as shall be determined by the governing body.  D. The bonds may be sold below,  at or above par. If an issue of bonds is sold below par,  the aggregate amount of discount plus interest to be paid on the bonds must not exceed the amount of interest that would be payable on the bonds over the maturity schedule prescribed by the governing body at the maximum rate set out in the resolution calling the election at which the bonds were voted. The amount of net premium associated with a bond issue may be used only for one or more of the following: 1. To pay costs incurred in issuing the bonds,  subject to section 35-452,  subsection C. 2. As a deposit in a debt service fund and used only to pay interest on the bonds. 3. For any other purpose,  if the political subdivision has voter authorization and available capacity under its debt limitations and the amount of net premium used for such purpose will reduce in an equal amount both: (a) The available aggregate indebtedness capacity of the political subdivision under the statutes and constitution of this state. (b) The principal amount authorized at the election for the political subdivision from which the issue of bonds is being sold. E. Any net premium used as provided in subsection D,  paragraph 3 of this section shall be amortized for all debt limitation purposes on a pro rata basis each year by multiplying the net premium used by a percentage equal to the percentage of the total principal amount of the bond issue that matures in that year. F. For the purposes of this section: 1. " Net premium"  means the difference between the par amount of the bond issue and the bond issue price determined pursuant to United States treasury regulations. 2. " Online bidding process"  means a procurement process in which the governing body receives bids electronically over the internet in a real-time,  competitive bidding event.
