Idaho Code § 43-2303
In addition to the permanent financing contemplated in this chapter the board of any district may borrow money and issue interim notes in evidence thereof whenever it is deemed advisable and in the interests of the district to borrow funds temporarily for any of the purposes herein provided in advance of permanent financing. The board may from time to time and pursuant to appropriate resolution borrow money and issue interim notes to evidence borrowing for the purpose of obtaining funds for any of the purposes authorized in section 43-2301, Idaho Code. Any resolution authorizing the issuance of interim notes shall describe generally the purpose for which such notes are to be issued and shall specify the principal amount, rate of interest and maturity date, which shall be the same for all interim notes and which shall be not to exceed five (5) years from the date of issue of such notes, and such other pertinent terms as may be specified in such resolution. The interim notes shall be issued from time to time by the board as funds are borrowed, in the manner the board may determine. Interest on the interim notes may be made payable semiannually, annually or at maturity. The interim notes may be made redeemable prior to maturity at the option of the board in the manner and upon the terms fixed by the resolution authorizing their issuance. Such interim notes shall be sold at such price or prices as may be determined by resolution of the board. All such interim notes and the interest thereon may be secured by a pledge of the proceeds of the revenues provided in subsection (e) of section 43-2301, Idaho Code, and shall be payable solely from such revenues and from the proceeds to be derived from the sale of any bonds for permanent financing authorized to be issued pursuant to this chapter. Contemporaneously with the issuance of the bonds as provided by this chapter, all interim notes, even though they may not have then matured, shall be paid, both principal and interest and applicable premium, if any, to date of payment, from the funds derived from the sale of bonds authorized hereunder for the permanent financing, and such interim notes shall thereupon be surrendered and canceled.
