The 2017 senior notes are repayable within one year and have been reclassified to short-term debt, see Note 12, "Short-Term Debt". On November 1, 2016, we adopted new guidance related to the presentation of debt issuance costs in the balance sheet. As a result, the amortized principal of long-term debt decreased by $8 million. The table above for October 31, 2016 reflects the new disclosure requirement. Please refer to Note 2, "New Accounting Pronouncements" for additional information.

All outstanding notes listed above are unsecured and rank equally in right of payment with all of Agilent’s other senior unsecured indebtedness. Other than described above, there have been no changes to the principal, maturity, interest rates and interest payment terms of the Agilent senior notes, detailed in the table above, in the six months ended April 30, 2017 as compared to the senior notes described in our Annual Report on Form 10-K for the fiscal year ended October 31, 2016. All interest rate swap contracts have been terminated and amounts to be amortized over the remaining life of the senior notes as of April 30, 2017 and October 31, 2016 are detailed above.
