35-473.01.  Refunding bonds issued in advance of maturity of the bonds to be refunded;  definition A. Refunding bonds,  designated as such,  may also be authorized,  issued and sold pursuant to this article for the purpose of refunding any bonds theretofore issued under the authority of article 3 of this chapter or under the authority of both article 3 of this chapter and title 9,  chapter 5,  article 3 or under the authority of title 15,  chapter 4,  article 5 and chapter 9,  article 7 or by any political subdivision that is a public,  corporate body under the laws of this state the property of which is exempt from taxation,  for the purpose of refunding any bonds,  theretofore issued under authority of law and payable from the proceeds of taxes,  including assessments,  which may be levied annually at uniform rates and are secured by property subject thereto in the political subdivision,  in advance of the maturity or call date of such bonds to be refunded. If the weighted average maturity of the refunding bonds is at least seventy-five percent of the weighted average maturity of the bonds being refunded,  no election on the issuance of the refunding bonds shall be required. If the refunding bonds are combined into a single issue with bonds authorized for nonrefunding purposes,  the bonds so authorized for nonrefunding purposes shall have been submitted at an election as otherwise provided by law. B. When refunding bonds issued pursuant to this section are sold,  the net proceeds shall be invested in obligations issued by or guaranteed by the United States government,  if these investments will mature with interest so as to provide funds to pay when due,  or called for redemption,  the bonds to be refunded together with interest thereon and redemption premiums,  if any,  and such proceeds or obligations shall,  and other funds legally available for such purposes may,  be deposited in the respective principal and interest redemption funds and shall be held in trust for the payment of the refunded bonds with interest and redemption premiums,  if any,  on maturity or upon an available redemption date or on an earlier voluntary surrender with the consent of the issuer. C. For bonds that are issued to refund outstanding bonds that are issued before September 1,  2016,  in advance of the maturity dates of such bonds,  the holder of the refunding bonds shall rely on the sufficiency of the funds or securities held in trust for the payment of the refunded bonds. The issuance of refunding bonds shall in no way infringe on the rights of the holder of the refunded bonds to rely on a tax levy for the payment of principal and interest on the refunded bonds if the investments in the redemption funds prove insufficient. The total aggregate of taxes levied to pay principal and interest on the refunding bonds in the aggregate shall not exceed the total aggregate principal and interest to become due on the refunded bonds from the date of issuance of the refunding bonds to the final date of maturity on the bonds being refunded. Subject to such limitation,  taxes in an amount sufficient to pay the interest on all refunding bonds issued pursuant to this section,  then outstanding,  the installments of the principal thereof becoming due and payable in the ensuing year,  and the annual portion of such sinking fund as may be set up for retirement thereof,  shall be levied,  assessed and collected as other taxes of the political subdivision and the proceeds therefrom kept in a special fund and used only for the purposes for which collected. D. For bonds that are issued to refund or refinance bonds that are issued from and after August 31,  2016,  in advance of the maturity dates of such bonds,  the holder of the refunded bonds shall rely on the sufficiency of the funds or securities held in trust for the payment of the refunded bonds. To the extent that payment of amounts on the refunded bonds is provided for by the deposit of funds and securities held in trust for the payment of the refunded bonds,  all obligations of the political subdivision to levy a tax for the payment of such amounts shall cease and terminate. The refunded bonds shall in no way infringe on the rights of the holders of the refunding bonds to rely on a tax levy for the payment of principal of and interest on the refunding bonds if the investments in the redemption funds prove insufficient. The total aggregate of taxes levied to pay principal of and interest on the refunding bonds in the aggregate shall not exceed the total aggregate principal and interest to become due on the refunded bonds from the date of issuance of the refunding bonds to the final date of maturity on the bonds being refunded. Subject to such limitation,  taxes in an amount sufficient to pay the interest on all refunding bonds issued pursuant to this section,  then outstanding,  the installments of the principal thereof becoming due and payable in the ensuing year,  and the annual portion of such sinking fund as may be set up for retirement thereof,  shall be levied,  assessed and collected as other taxes of the political subdivision and the proceeds therefrom kept in a special fund and used only for the purposes for which collected. E. Proceedings pursuant to this section shall be had by the board or boards that would be authorized to issue and sell the bonds to be refunded if such bonds were then to be issued and sold. The refunding bonds to be issued pursuant hereto may be of serial,  including semiannual,  or term maturities payable at any time on or before the maximum maturity date otherwise authorized by this article,  and the provisions relating to execution,  validity,  records,  place of payment and payment,  cancellation and destruction on maturity of the bonds to be refunded shall apply to such refunding bonds. F. Refunding bonds to be issued pursuant to this section may be combined with bonds otherwise authorized,  provided that they are of equal priority. G. The powers conferred by this section are in addition to,  and not in substitution of,  and the limitations imposed by this section shall not affect the powers conferred by any other law. H. The amount of net premium associated with a refunding bond issue may be used only for one or more of the following: 1. To fund the escrow account to pay the bonds to be refunded. 2. To pay the costs incurred in issuing the refunding bonds. 3. As a deposit in a debt service fund and only to pay interest on the bonds. I. If the net premium associated with a refunding bond issue is used to fund the escrow account to pay the bonds to be refunded and the principal amount of the refunding bonds is less than the principal amount of the bonds being refunded,  the difference between such principal amounts reduces the available aggregate indebtedness capacity of the political subdivision under the constitution and statutes of this state in an equal amount,  provided that the difference in the amounts may not exceed the aggregate available indebtedness capacity of the political subdivision. The difference in principal amount will not cause any increase or decrease in the principal amount authorized pursuant to any bond election. Any net premium used as provided in this subsection 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. J. For the purposes of this section,  " 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.
