[1] During the three and six months ended June 30, 2013 and 2012, the LP Units (which represent the right to receive Class A Shares upon exchange) were antidilutive and consequently the effect of their exchange into Class A Shares has been excluded from the calculation of diluted net income per share attributable to Evercore Partners Inc. common shareholders. The units that would have been included in the computation of diluted net income per share attributable to Evercore Partners Inc. common shareholders if the effect would have been dilutive were 6,680 and 6,734 for the three and six months ended June 30, 2013, respectively, and 9,000 and 9,068 for the three and six months ended June 30, 2012, respectively.
