[1] At September 30, 2015, the Company has outstanding Class G and H limited partnership interests of Evercore LP ("Class G and H LP Interests") which are contingently exchangeable into Class E LP Units, and ultimately Class A Shares, as they are subject to certain performance thresholds being achieved. See Note 14 for a further discussion. For the purposes of calculating diluted net income per share attributable to Evercore Partners Inc. common shareholders, the Company’s Class G and H LP Interests will be included in diluted weighted average Class A Shares outstanding as of the beginning of the period in which all necessary performance conditions have been satisfied. If all necessary performance conditions have not been satisfied by the end of the period, the number of shares that will be included in diluted weighted average Class A Shares outstanding will be based on the number of shares that would be issuable if the end of the reporting period were the end of the performance period. For the three and nine months ended September 30, 2015, 2,271 and 1,269 of these interests, respectively, were assumed to be converted to an equal number of Class A Shares for purposes of computing diluted EPS.
