Refunding bonds.

A. No bonds may be refunded under Section 6-17-14 through 6-17-18 NMSA 1978, unless they mature or are callable for prior redemption under their terms within fifteen years from the date of issuance of the refunding bonds, or unless the holders voluntarily surrender them for exchange or payment. B. Outstanding bonds of more than one issue may be refunded by bonds of one or more issues. Bonds for refunding and bonds for any other purposes authorized in Chapter 73, Article 29 NMSA 1953, may be issued separately or in combination in one series or more. C. If any officer whose signature or facsimile signature appears on any bonds or coupons ceases to hold his office before delivery of the bonds, his signature or its facsimile is valid for all purposes as if he had remained in office until the delivery. D. Where refunding bonds are sold, the net proceeds may, in the discretion of the issuing board, be invested in obligations of the United States or any of its agencies, or in obligations fully guaranteed by the United States, but the obligations purchased must have maturities and bear rates of interest payable at times to ensure the existence of money sufficient to pay the bonds to be refunded when due or when redeemed pursuant to call for redemption, together with interest and redemption premiums, if any. E. As used in this section, "net proceeds" means the gross proceeds of the bonds after deduction of all accrued interest and expenses incurred in connection with the authorization and issuance of the bonds and the refunding of the outstanding bonds, including fiscal agent fees and commissions and all discounts incurred in the resale of the refunding bonds by the original purchaser. F. All obligations purchased with refunding bond proceeds shall be deposited in trust with a bank doing business in this state and a member of the federal deposit insurance corporation, to be held, liquidated and the proceeds of the liquidation paid out for payment of the bonds to be refunded, along with interest and redemption premiums, as the refunded bonds become due or subject to redemption under call for redemption previously made, or upon earlier voluntary surrender with the consent of the issuing board. G. The determination of the board issuing refunding bonds that the conditions of Chapter 73, Article 29 NMSA 1953, upon the issuance of refunding bonds have been met is conclusive in the absence of fraud or arbitrary and gross abuse of discretion.
