(1)	Earnings per share were computed independently for each of the periods presented; therefore, the sum of the earnings per share amounts for the quarters may not equal the total for the year.


(2)	Net income and earnings per share data were revised from previously reported amounts due to the adoption of ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. See Note 1 — Summary of Significant Accounting Policies.
