For all periods presented, basic and diluted net loss per share is the same, as any additional common stock equivalents would be anti-dilutive. We excluded 3.2 million of stock options from the weighted average diluted common shares outstanding for the three months ended March 31, 2017 and 2016, respectively, which would have been anti-dilutive due to the net loss in those periods. In addition, we excluded 2.0 million and 1.8 million of restricted stock units from the calculation of weighted average diluted common shares outstanding for the three months ended March 31, 2017 and 2016, respectively, which would have been anti-dilutive due to the net loss
