For the three months ended March 31, 2017 and 2016, options to purchase 0.1 million and 0.1 million shares of common stock, respectively, 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 three months ended March 31, 2017 and 2016, restricted stock units (“RSUs”) of 0.0 million and 0.2 million, respectively, were outstanding, but not included in the computation of diluted net income per share because the effect would have been anti-dilutive.
