[1] In conjunction with the issuance of the April 2025 Notes we entered into 8-year fixed-to-fixed cross-currency swaps which have the effect of economically converting the April 2025 Notes to euro-denominated debt at a fixed rate of 3.850%. On April 25, 2022, we settled existing fixed-to-fixed cross-currency swaps on $100 of the April 2025 Notes. See Note 13 for additional information.
