[1] In fiscal 2018 we entered into certain cross-currency interest rate swap agreements that have the economic effect of converting our fixed-rate, Euro-denominated debt, including annual interest payments and the payment of principal at maturity, to a variable-rate, U.S. Dollar-denominated debt of $871 million based on LIBOR. The effective interest rates as of May 31, 2025 after consideration of the cross-currency interest rate swap agreements were 7.77% for the July 2025 Notes. Refer to Note 1 for a description of our accounting for fair value hedges. The July 2025 Notes were repaid in full upon maturity in July 2025.
