[1] | Interest was tied to AUD LIBOR at May 31, 2016, and averaged 2.92% for AUD denominated debt ($13,050), 1.075% on EUR denominated debt ($131,692) and 1.544% on our swing-line ($57,139). Interest was tied to AUD LIBOR at May 31, 2015, and averaged 3.095% for AUD denominated debt ($10,316), 1.075% on EUR denominated debt ($16,490), 1.265% on Euro LIBOR denominated debt ($70,000) and 1.259% on our swing-line ($14,237).
[2] | The $250.0 million aggregate principal amount of the notes due 2018 is adjusted for the amortization of the original issue discount, which approximated $0.6 million and $1.0 million at May 31, 2016 and 2015, respectively. 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 6.704% for both years presented.
[3] | Includes the combination of the October 2009 initial issuance of $300.0 million aggregate principal amount and the May 2011 issuance of an additional $150.0 million aggregate principal amount of these notes. The $300.0 million aggregate principal amount of the notes due 2019 from the initial issuance is adjusted for the amortization of the original issue discount, which approximated $0.1 million and $0.1 million at May 31, 2016 and 2015. The original issue discount effectively reduced the ultimate proceeds from the October 2009 financing. The effective interest rate on the notes issued in October 2009, including the amortization of the discount, is 6.139%. The additional $150.0 million aggregate principal amount of the notes due 2019 issued in May 2011 is adjusted for the unamortized premium received at issuance, which approximated $5.5 million and $6.9 million at May 31, 2016 and 2015, respectively. The premium effectively increased the proceeds from the financing. The effective interest rate on the $150.0 million notes issued in May 2011 is 4.934%.
[4] | The $250.0 million face amount of the notes due 2045 is adjusted for the amortization of the original issue discount, which approximated $1.5 million at May 31, 2016 and 2015. 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 5.29%.
