Whenever a majority of the qualified electors of a district voting on a proposal to issue bonds has authorized the district to issue bonds for an authorized purpose, the district may borrow money without any other election in anticipation of taxes, the proceeds of the bonds or any other revenues of the district, and may issue interim debentures to evidence the amount so borrowed. Interim debentures may mature at such time 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- 18-64 and 72-18-65 N.M. Stat. Ann., interim debentures shall be issued as provided for securities in Sections 72-18-49 through 72-18-61 N.M. Stat. Ann.. Taxes, other revenues of the district, 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. Bonds pledged as collateral security for the payment of any interim debentures shall mature at such time as the board may determine, not exceeding forty years from the date of either any of such bonds or any such interim debentures, whichever date is 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 debentures secured by a pledge of such bonds.
