Share-Based and Other Deferred Compensation

Share-Based and Other Deferred Compensation

During the three months ended March 31, 2014, the Company granted employees 1,798 Service-based Awards. These awards had grant date fair values from $54.29 to $58.67 per share. During the three months ended March 31, 2014, 2,039 Service-based Awards vested and 91 Service-based Awards were forfeited.

During 2011, the Company launched a deferred compensation program providing 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. Compensation expense related to this deferred compensation program was $894 and $992for the three months ended March 31, 2014 and 2013, respectively.

Compensation expense related to Service-based Awards, excluding compensation expense related to the amortization of LP Units, was $22,244 and $20,593for the three months ended March 31, 2014 and 2013, respectively. Compensation expense related to the amortization of these LP Units was $5,610 for the three months ended March 31, 2013. Compensation expense related to acquisition-related Awards and deferred cash consideration was $2,241 and $932, respectively, for the three months ended March 31, 2014, and $3,608 and $1,049, respectively, for the three months ended March 31, 2013.

During the third quarter of 2013, the Board of Directors of the Company approved the Long-term Incentive Plan, which 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.

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 $2,647 and $1,667for the three months ended March 31, 2014 and 2013, respectively. The remaining unamortized amount of these awards was $13,378 as of March 31, 2014.
