[1] Includes stock-based compensation expense as follows:

[2] a) Interest expense in fiscal 2017 and the fourth quarter of fiscal 2016 includes interest and fees associated with financing commitments entered into in connection with the Acquisition.

[3] b) Provision for income taxes in the second quarter of fiscal 2017 included a tax benefit of $15.0 million for the release of a state tax credit valuation allowance as a result of the Acquisition. Provision for income taxes in the third quarter of fiscal 2017 included approximately $98.2 million of tax expense incurred during the quarter as part of the post-Acquisition integration, partially offset by a tax benefit of $50.5 million related to the reduction of reserves and related interest resulting from the U.S. Tax Court’s favorable ruling, as well as lower statutory tax rates applicable to our operations in the foreign jurisdictions in which we earn income.
