N.M. Stat. § 72-17-89
Notwithstanding any limitation or other provision herein, whenever a majority of the qualified electors of the authority voting on a proposal to issue bonds has authorized the authority to issue bonds for any purpose herein authorized, the authority is authorized to borrow money without any other election in anticipation of taxes, the proceeds of such bonds or any other revenues of the authority, or any combination thereof, and to issue interim debentures to evidence the amount so borrowed. Interim debentures may mature at such time or times not exceeding a period of time equal to the estimated time needed to effect the purpose for which the bonds are so authorized to be issued, plus two years, as the board may determine. Except as otherwise provided in this section and in Sections 72-17-90 and 72-17-91 NMSA 1978, interim debentures shall be issued as provided herein for securities in Sections 72-17-47 through 72-17-80 NMSA 1978. Taxes, other revenues of the authority, including without limiting the generality of the foregoing, proceeds of bonds to be thereafter issued or reissued or bonds issued for the purpose of securing the payment of interim debentures may be pledged for the purpose of securing the payment of the interim debentures. Any bonds pledged as collateral security for the payment of any interim debentures shall mature at such time or times as the board may determine, but in no event exceeding forty years from the date of either any of such bonds or any of such interim debentures, whichever date be the earlier. Any such bonds pledged as collateral security shall not be issued in an aggregate principal amount exceeding the aggregate principal amount of the interim debenture or interim debenture secured by a pledge of such bonds, nor shall they bear interest at any time that, with any interest accruing at the same time on the interim debenture or interim debentures so secured, exceeds six percent per year.
