[1] The Company has outstanding LP Units in its subsidiary, Evercore LP, which give the holders the right to receive Class A Shares upon exchange on a one for one basis. During the three and nine months ended September 30, 2014 and 2013, the LP Units 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 denominator of the computation of diluted net income (loss) per share attributable to Evercore Partners Inc. common shareholders if the effect would have been dilutive were 4,670 and 4,823 for the three and nine months ended September 30, 2014, respectively, and 6,592 and 6,690 for the three and nine months ended September 30, 2013, respectively. The adjustment to the numerator, Diluted net income attributable to Class A common shareholders, if the effect would have been dilutive, would have been $3,200 and $7,987 for the three and nine months ended September 30, 2014, respectively, and $3,035 and $7,880 for the three and nine months ended September 30, 2013, respectively. In computing this adjustment, the Company assumes that all vested LP Units, and all unvested LP Units after applying the treasury stock method, are converted into Class A Shares, that all earnings attributable to those shares are attributed to Evercore Partners Inc. and, that it has adopted a conventional corporate tax structure and is taxed as a C Corporation in the U.S. at prevailing corporate tax rates. The Company does not anticipate that the LP Units will result in a dilutive computation in future periods.
