The Company’s potentially dilutive securities, which included stock options, RSUs, preferred stock and shares of restricted common stock that were issued but not yet vested, have been excluded from the computation of diluted net loss per share since the effect would be to reduce the net loss per share. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The following table presents potential common shares excluded from the calculation of diluted net loss per share attributable to common stockholders for both the three and six months ended June 30, 2016 and 2015. All share amounts presented in the table below represent the total number outstanding as of June 30.
