New Mexico Statutes 4-62-7. Revenue bonds; refunding authorization
A. Any county having issued revenue bonds as authorized in Sections 4-62-1 through 4-62-6 N.M. Stat. Ann. or pursuant to any other laws enabling the governing body of any county having issued revenue bonds payable only out of the pledged revenue may issue refunding revenue bonds for the purpose of refinancing, paying and discharging all or any part of the outstanding bonds of any outstanding issues:
(1) for the acceleration, deceleration or other modification of the payment of such obligations, including without limitation any capitalization of any interest thereon in arrears or about to become due for any period not exceeding one year from the date of the refunding bonds;
(2) for the purpose of reducing interest costs or effecting other economies; (3) for the purpose of modifying or eliminating restrictive contractual limitations pertaining to the issuance of additional bonds, otherwise concerning the outstanding bonds or to any facilities relating thereto; or
(4) for any combination of such purposes.
B. The county may pledge irrevocably for the payment of interest and principal on refunding bonds the appropriate pledged revenues that may be pledged to an original issue of bonds as provided in Section 4-62-1 N.M. Stat. Ann.. This section permits the pledge of revenues from one source to the payment of bonds that refund bonds payable from a different source of revenue.
C. Bonds for refunding and bonds for any purpose permitted by Section 4-62-1 N.M. Stat. Ann. may be issued separately or issued in combination in one or more series.
