Notwithstanding the provisions of chapter 16 of the Kansas Statutes Annotated, and amendments thereto, to the contrary, or any other statute, there is no maximum interest rate or charge or usury rate restriction between or among a fiduciary financial institution and a fidfin trust if the interest rate or charge is established by written agreement. A "written agreement" means a document in writing, whether in physical or electronic form, in which the parties have demonstrated their agreement to the terms and conditions of an extension of credit, including the rate of interest.
