For the three months ended March 31, 2019 and 2018, there were no options to purchase shares of common stock outstanding that were excluded from 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 three months ended March 31, 2019 and 2018, there were restricted stock units (“RSUs”) of 331 thousand and 47 thousand, respectively, outstanding which were excluded from the computation of diluted net income per share because the effect would have been anti-dilutive.
