We have not included the impact of Class B common stock because these shares are entitled to an insignificant amount of economic participation.

(a)Class A partnership units may be exchanged for Moelis & Company Class A common stock on a one‑for‑one basis, subject to applicable lock‑up, vesting and transfer restrictions. If all Class A partnership units were to be exchanged for Class A common stock, fully diluted Class A common stock outstanding would be 62,321,050 and 56,273,530 for the three months ended March 31, 2017 and 2016, respectively. In computing the dilutive effect, if any, that the aforementioned exchange would have on net income (loss) per share, net income (loss) available to holders of Class A common stock would be adjusted due to the elimination of the noncontrolling interests in consolidated entities associated with the Group LP Class A partnership units (including any tax impact). For the three months ended March 31, 2017 and 2016, such exchange is not reflected in diluted net income (loss) per share as the assumed exchange is not dilutive.

(b)During the three months ended March 31, 2017 and 2016, certain shares of Moelis & Company’s Class A common stock assumed to be issued pursuant to certain RSUs as calculated using the treasury stock method were antidilutive and therefore have been excluded from the calculation of diluted net income (loss) per share attributable to Moelis & Company. During the three months ended March 31, 2017 and 2016, the additional weighted average amount of RSUs that would have been included in this calculation if the effect were dilutive would have been 896 and 37,950 units, respectively. Additionally, during the three months ended March 31, 2017 and 2016, the additional weighted average amount of options that would have been included in this calculation if the effect were dilutive would have been 0 and 2,933,468 options, respectively.
