Item 6. Selected Financial Data-Unaudited

The following selected consolidated financial data should be read in conjunction with our consolidated financial statements and the notes thereto and the information contained in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” Historical results are not necessarily indicative of future results. The notes below the table are provided for comparability purposes due to adoptions of accounting pronouncements or to describe significant transactions that may not occur frequently.

(1) On the first day of fiscal 2018, we adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606),” which provided a new basis of accounting for our revenue arrangements. Because of the adoption, results of operations for fiscal 2019 and 2018 are not comparable to the results of operations for the other fiscal years presented in the table above.

(2) During fiscal 2017, we recorded a provisional income tax expense of $96.8 million related to the income tax effects of the Tax Act, which included $67.2 million related to the one-time transition tax on the mandatory deemed repatriation of foreign earnings.

We finalized our other fiscal 2017 provisional estimates without change during fiscal 2018.

(4) During fiscal 2018, we prepaid the outstanding principal balance and accrued interest on our $300.0 million 2019 Term Loan.
