In March 2016, the Financial Accounting Standards Board (FASB) issued ASU 2016-09, "Compensation-Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting." The Company elected to early adopt ASU 2016-09 in the first quarter of fiscal 2017. As required by ASU 2016-09, excess tax benefits recognized on stock-based compensation expense are classified as an operating activity in the consolidated statements of cash flows and the Company has elected to apply this provision on a prospective basis. The Company also elected to account for forfeitures as they occur and recorded a one-time adoption expense of $0.4 million to retained earnings. See Note 15. Taxes for additional information on tax impacts.
