[1] During the first quarter of fiscal 2017, the Company adopted ASU 2015-03, which simplifies the presentation of debt issuance costs by requiring debt issuance costs to be presented as a deduction from the corresponding debt liability rather than an asset that is amortized. The Company adopted the standard retrospectively for the prior period presented.
