[1] | The $300.0 million face amount of the notes due 2032 is adjusted for the amortization of the original issue discount, which approximated $0.6 million at May 31, 2022. The original issue discount effectively reduced the ultimate proceeds from the financing. The effective interest rate on the notes, including the amortization of the discount, is 2.976%. At May 31, 2022, the notes are adjusted for debt issuance costs, net of amortization, for approximately $2.9 million.
