(1) We adopted an accounting standard related to stock-based compensation effective February 1, 2016, which required the excess tax benefit to be reflected in our provision for income taxes rather than in additional paid-in-capital. The total related excess tax benefit recognized for fiscal year 2018 and 2017 was $197 million and $82 million, respectively.

(2) We recognized a provisional tax benefit of $133 million, which was included as a component of income tax expense.
