[1] "Notes payable and term loan" on our Condensed Consolidated Balance Sheets as of January 31, 2017 and October 31, 2016 consists of the total senior secured, senior, senior amortizing and senior exchangeable notes and senior secured term loan shown above, as well as accrued interest of $31.7 million and $32.4 million, respectively.
[2] As discussed in Note 1, we adopted ASU 2015-03 in January 2017. We applied the new guidance retrospectively to all prior periods presented in the financial statements to conform to the fiscal 2017 presentation. As a result, $20.2 million of debt issuance costs at October 31, 2016, were reclassified from prepaids and other assets to a reduction in our senior secured term loan, senior secured, senior, senior amortizing and senior exchangeable notes. Debt issuance costs at January 31, 2017 were $18.6 million.
