Share-Based and Other Deferred Compensation	Share-Based and Other Deferred Compensation Equity Grants During the six months ended June 30, 2016, the Company granted employees 2,920 RSUs that are Service-based Awards. Service-based Awards granted during the six months ended June 30, 2016 had grant date fair values of $44.67 to $50.81 per share. During the six months ended June 30, 2016, 2,205 Service-based Awards vested and 54 Service-based Awards were forfeited. Compensation expense related to Service-based Awards was $28,516 and $57,278 for the three and six months ended June 30, 2016, respectively, and $27,465 and $54,960 for the three and six months ended June 30, 2015, respectively. During the second quarter of 2016, the Company's stockholders approved the Amended and Restated 2016 Evercore Partners Inc. Stock Incentive Plan. The amended plan, among other things, authorizes an additional 10,000 shares of the Company's Class A Shares. Deferred Cash Program The Company's deferred compensation program provides participants the ability to elect to receive a portion of their deferred compensation in cash, which is indexed to a notional investment portfolio and vests ratably over four years and requires payment upon vesting. During the first quarter of 2016, the Company granted $38,647 of deferred cash awards pursuant to the deferred compensation program. Compensation expense related to this deferred compensation program was $4,557 and $7,117 for the three and six months ended June 30, 2016, respectively, and $448 and $1,008 for the three and six months ended June 30, 2015, respectively. Acquisition-related LP Units Equities business - In conjunction with the acquisition of the operating businesses of International Strategy & Investment ("ISI") in 2014, the Company issued Evercore LP units and interests which have been treated as compensation, including 710 vested Class E LP Units and an allocation of the value, attributed to post-combination service, of 710 Class E LP Units that were unvested and vest ratably on October 31, 2015, 2016 and 2017 and become exchangeable once vested, subject to continued employment with the Company. The units will become exchangeable into Class A common shares of the Company subject to certain liquidated damages and continued employment provisions. Compensation expense related to Class E LP Units was $4,937 and $10,550 for the three and six months ended June 30, 2016, respectively, and $4,893 and $9,961 for the three and six months ended June 30, 2015, respectively. The Company also issued 538 vested and 540 unvested Class G LP Interests, which vest ratably on February 15, 2016, 2017 and 2018, and 2,044 vested and 2,051 unvested Class H LP Interests, which will vest ratably on February 15, 2018, 2019 and 2020. The Company’s vested Class G and Class H LP Interests will become exchangeable into Class A common shares of the Company subject to the achievement of certain performance targets. The Company’s vested Class G LP Interests become exchangeable in February 2016, 2017 and 2018 if certain earnings before interest and taxes, excluding underwriting, ("Management Basis EBIT") margin thresholds within a range of 12% to 16%, are achieved for the calendar year preceding the date the interests become exchangeable. The Company’s vested Class H LP Interests will become exchangeable in February 2018, 2019 and 2020 if certain average Management Basis EBIT and Management Basis EBIT margin thresholds, within ranges of $8,000 to $48,000 and 7% to 17%, respectively, are achieved for the three calendar years preceding the date the interests become exchangeable. In the event of death, disability or termination of employment without cause, unvested Class G and H LP Interests will be canceled or may vest based on determination of expected performance, based on a decision by Management. In February 2016, 371 Class G LP Interests achieved their performance targets and were converted to the same number of Class E LP Units. Based on Evercore ISI’s results for 2015 and for the first six months of 2016, the Company determined that the achievement of certain of the remaining performance thresholds for the remaining Class G and H LP Interests was probable at June 30, 2016. This determination assumes Management Basis EBIT margin of 16.2% and annual Management Basis EBIT of $38,820 being achieved over the remaining performance period for Evercore ISI which would result in 3,767 Class G and H LP Interests vesting and becoming exchangeable into Class E LP Units. For the six months ended June 30, 2015, the Company had determined that the achievement of certain of the remaining performance thresholds for the Class G and H LP Interests was probable and assumed a Management Basis EBIT margin of 15% and annual Management Basis EBIT of $32,800 being achieved over the performance period for Evercore ISI. Accordingly, $15,698 and $41,750 of expense was recorded for the three and six months ended June 30, 2016, respectively, and $13,170 and $33,313 of expense was recorded for the three and six months ended June 30, 2015, respectively, for the Class G and H LP Interests. Assuming the maximum thresholds for the Class G and H LP Interests were considered probable of achievement at June 30, 2016, an additional $21,606 of expense would have been incurred in the second quarter ended June 30, 2016 and the remaining expense to be accrued over the future vesting period extending from July 1, 2016 to February 15, 2020 would be $141,922. In that circumstance, the total number of Class G and H LP Interests that would vest and become exchangeable to Class E LP Units would be 4,957. Conversely, the life to date actual accrued expense related to unvested Class G and H LP Interests as of June 30, 2016 was $83,486, which will be reversed if the actual performance falls below, or is deemed probable of falling below, the minimum thresholds prior to vesting. Other Acquisition Related Lexicon - Compensation expense related to The Lexicon Partnership LLP ("Lexicon") Acquisition-related Awards and deferred cash consideration was $622 and $330, respectively, for the three months ended June 30, 2015, and $1,237 and $301, respectively, for the six months ended June 30, 2015. Long-term Incentive Plan The Company's Long-term Incentive Plan provides for incentive compensation awards to Advisory Senior Managing Directors, excluding executive officers of the Company, who exceed defined benchmark results over a four-year performance period beginning January 1, 2013. These awards will be paid, in cash or Class A Shares, at the Company's discretion, in the two years following the performance period, to Senior Managing Directors employed by the Company at the time of payment. These awards are subject to retirement eligibility requirements. The Company periodically assesses the probability of the benchmarks being achieved and expenses the probable payout over the requisite service period of the award. The compensation expense related to these awards was $3,739 and $7,478 for the three and six months ended June 30, 2016, respectively, and $1,530 and $3,043 for the three and six months ended June 30, 2015, respectively. Employee Loans Receivable Periodically, the Company provides new and existing employees with cash payments in the form of loans and/or other cash awards which are subject to ratable vesting terms with service requirements ranging from one to five years. Generally, the terms of these awards include a requirement of either full or partial repayment of these awards based on the terms of their employment agreements with the Company. In circumstances where the employee meets the Company's minimum credit standards, the Company amortizes these awards to compensation expense over the relevant service period which is generally the period they are subject to forfeiture. Compensation expense related to these awards was $5,699 and $10,531 for the three and six months ended June 30, 2016, respectively, and $4,371 and $8,951 for the three and six months ended June 30, 2015, respectively. The remaining unamortized amount of these awards was $30,509 as of June 30, 2016. Separation Benefits The Company granted separation benefits to certain employees, resulting in expense included in Employee Compensation and Benefits of approximately $1,195 and $3,223 for the three and six months ended June 30, 2016, respectively, and $2,188 and $3,795 for the three and six months ended June 30, 2015, respectively. In conjunction with these arrangements, the Company distributed cash payments of $623 and $1,762 for the three and six months ended June 30, 2016, respectively, and $321 and $1,531 for the three and six months ended June 30, 2015, respectively. The Company also granted separation benefits to certain employees, resulting in expense included in Special Charges of approximately ($102) and $1,863 for the three and six months ended June 30, 2015, respectively. In conjunction with these arrangements, the Company distributed cash payments of $487 for the three and six months ended June 30, 2015. See Note 4 for further information.

The units will become exchangeable into Class A common shares of the Company subject to certain liquidated damages and continued employment provisions.

The Company also issued 538 vested and 540 unvested Class G LP Interests, which vest ratably on February 15, 2016, 2017 and 2018, and 2,044 vested and 2,051 unvested Class H LP Interests, which will vest ratably on February 15, 2018, 2019 and 2020. The Company’s vested Class G and Class H LP Interests will become exchangeable into Class A common shares of the Company subject to the achievement of certain performance targets. The Company’s vested Class G LP Interests become exchangeable in February 2016, 2017 and 2018 if certain earnings before interest and taxes, excluding underwriting, ("Management Basis EBIT") margin thresholds within a range of 12% to 16%, are achieved for the calendar year preceding the date the interests become exchangeable. The Company’s vested Class H LP Interests will become exchangeable in February 2018, 2019 and 2020 if certain average Management Basis EBIT and Management Basis EBIT margin thresholds, within ranges of $8,000 to $48,000 and 7% to 17%, respectively, are achieved for the three calendar years preceding the date the interests become exchangeable. In the event of death, disability or termination of employment without cause, unvested Class G and H LP Interests will be canceled or may vest based on determination of expected performance, based on a decision by Management.

In February 2016, 371 Class G LP Interests achieved their performance targets and were converted to the same number of Class E LP Units.

Based on Evercore ISI’s results for 2015 and for the first six months of 2016, the Company determined that the achievement of certain of the remaining performance thresholds for the remaining Class G and H LP Interests was probable at June 30, 2016. This determination assumes Management Basis EBIT margin of 16.2% and annual Management Basis EBIT of $38,820 being achieved over the remaining performance period for Evercore ISI which would result in 3,767 Class G and H LP Interests vesting and becoming exchangeable into Class E LP Units. For the six months ended June 30, 2015, the Company had determined that the achievement of certain of the remaining performance thresholds for the Class G and H LP Interests was probable and assumed a Management Basis EBIT margin of 15% and annual Management Basis EBIT of $32,800 being achieved over the performance period for Evercore ISI. Accordingly, $15,698 and $41,750 of expense was recorded for the three and six months ended June 30, 2016, respectively, and $13,170 and $33,313 of expense was recorded for the three and six months ended June 30, 2015, respectively, for the Class G and H LP Interests.

Assuming the maximum thresholds for the Class G and H LP Interests were considered probable of achievement at June 30, 2016, an additional $21,606 of expense would have been incurred in the second quarter ended June 30, 2016 and the remaining expense to be accrued over the future vesting period extending from July 1, 2016 to February 15, 2020 would be $141,922. In that circumstance, the total number of Class G and H LP Interests that would vest and become exchangeable to Class E LP Units would be 4,957. Conversely, the life to date actual accrued expense related to unvested Class G and H LP Interests as of June 30, 2016 was $83,486, which will be reversed if the actual performance falls below, or is deemed probable of falling below, the minimum thresholds prior to vesting.
