N.M. Stat. § 6-25-21
The authority is authorized to issue economic development revolving fund bonds for the purpose of refunding any economic development revolving fund bonds then outstanding, including the payment of any redemption premiums and any interest accrued or to accrue to the date of redemption of the outstanding economic development revolving fund bonds. Until the proceeds of the bonds issued for the purpose of refunding outstanding economic development revolving fund bonds are applied to the purchase, retirement or redemption of the outstanding economic development revolving fund bonds, the proceeds may be placed in escrow and be invested and reinvested. The interest, income and profits, if any, earned or realized on any such investment may also be applied to the payment of the outstanding economic development revolving fund bonds to be refunded by purchase, retirement or redemption. After the terms of the escrow have been fully satisfied, any balance may be returned to the authority for use by it in any lawful manner. All such refunding bonds shall be issued and secured and shall be subject to the provisions of the Statewide Economic Development Finance Act in the same manner and to the same extent as any other bonds issued pursuant to that act.
