Idaho Code § 67-8721

In connection with, or incidental to, the issuance or carrying of bonds, but only for the purpose of reducing the amount or duration of payment, interest rate, spread or similar risk, or to result in a lower cost of borrowing, and not for purposes of investment or speculation, the authority may enter into contracts which the authority determines to be necessary or appropriate to hedge such risk or to place the obligation of the bonds, in whole or in part, on the interest rate, cash flow, or other basis desired by the authority, including without limitation, contracts commonly known as interest rate swap agreements, interest rate caps or floors, forward payment conversion agreements, futures or hedge contracts.
