[1] During the first quarter of 2017 we adopted ASU 2016-09, Improvements to Employee Share-Based Payment Accounting. The amendments in this ASU require that all excess tax benefits and tax deficiencies associated with share-based compensation be recognized in income tax expense or benefit in the income statement. This guidance was adopted on a prospective basis with no change to prior period amounts.
