[1] During the three and nine months ended September 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 (loss) per share attributable to Evercore Partners Inc. common shareholders. The units that would have been included in the computation of diluted net income (loss) per share attributable to Evercore Partners Inc. common shareholders if the effect would have been dilutive were 6,592 and 6,690 for the three and nine months ended September 30, 2013, respectively, and 8,905 and 8,993 for the three and nine months ended September 30, 2012, respectively.
