______________________

(1) Diluted net income per share is computed independently for each period presented. Consequently, the sum of the quarters may not equal the total net income per share for the year. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income.

(2) The fourth quarter of 2017 reflects an incremental tax provision related to the remeasurement of our net deferred tax assets as a result of the enactment of the TCJA.
