For the years ended December 31, 2019,  2018 and 2017, there were no options to purchase shares of common stock or performance-based restricted stock that were outstanding but not included in the computation of diluted net income per share because the exercise price exceeded the value of the shares and the effect would have been anti-dilutive. For the years ended December 31, 2019,  2018 and 2017, restricted stock units of 28 thousand, 212 thousand, and 21 thousand, respectively, were outstanding but not included in the computation of diluted net income per share because the effect would have been anti-dilutive.
