Noncontrolling interest related to the assumed exchange of LP Units for Class A common shares										[1]		[1]		[1]

[1] During the years ended December 31, 2012, 2011 and 2010, 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 8,695, 10,356 and 13,724 for the years ended December 31, 2012, 2011 and 2010, respectively
