[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, 2022 and 2021 after consideration of the cross-currency interest rate swap agreements were 4.10% and 3.15%, respectively, for the July 2025 Notes. Refer to Note 1 for a description of our accounting for fair value hedges.

[2] We entered into certain interest rate swap agreements that had the economic effects of modifying the fixed-interest obligations associated with the 2.80% senior notes that were outstanding as of May 31, 2021 and that were due and were settled in July 2021 (July 2021 Notes) so that the interest payable on these notes effectively became variable based on LIBOR. The effective interest rates after consideration of these fixed to variable interest rate swap agreements was 0.87% for the July 2021 Notes as of May 31, 2021. Refer to Note 1 for a description of our accounting for fair value hedges.

[3] In July 2013, we issued €750 million of 3.125% senior notes due July 2025 (July 2025 Notes). Principal and unamortized discount/issuance costs for the July 2025 Notes in the table above were calculated using foreign currency exchange rates, as applicable, as of May 31, 2022 and May 31, 2021, respectively. The July 2025 Notes are registered and trade on the New York Stock Exchange.
