Share-Based and Deferred Compensation and Employee Ownership Plans

The Company issues share based compensation under the 2006 Equity and Incentive Plan, the 2007 Equity and Incentive Plan (both established prior to the November 2009 transaction between Ramius and Cowen) and the Cowen Group, Inc. 2010 Equity and Incentive Plan (collectively, the “Equity Plans”). The Equity Plans permit the grant of options, restricted shares, restricted stock units, stock appreciation rights ("SAR's") and other equity based awards to the Company's employees and directors. Stock options granted generally vest over two-to-five-year periods and expire seven years from the date of grant. Restricted shares and restricted share units issued may be immediately vested or may generally vest over a two-to-five-year period. SAR's vest and expire after five years from grant date. Awards are subject to the risk of forfeiture. As of March 31, 2016, there were approximately 1.3 million shares available for future issuance under the Equity Plans.

Under the 2010 Equity Plan, the Company awarded $25.6 million of deferred cash awards to its employees during the three months ended March 31, 2016. These awards vest over a four year period and accrue interest between 0.70% to 0.75% per year. As of March 31, 2016, the Company had unrecognized compensation expense related to deferred cash awards of $49.2 million.

The Company measures compensation cost for share based awards according to the equity method. In accordance with the expense recognition provisions of those standards, the Company amortizes unearned compensation associated with share based awards on a straight-line basis over the vesting period of the option or award. In relation to awards under the Equity Plans, the Company recognized compensation expense of $6.4 million and $4.2 million for the three months ended March 31, 2016 and 2015, respectively. The income tax effect recognized for the Equity Plans was a benefit of $3.1 million and $0.1 million for the three months ended March 31, 2016 and 2015, respectively.

Stock Options and Stock Appreciation Rights

The Company values options and SAR's on grant date using the Black-Scholes valuation model which requires the Company to make assumptions regarding the expected term, volatility, risk-free rate and dividend yield:

Expected term. Expected term represents the period of time that awards granted are expected to be outstanding. The Company elected to use the "simplified" calculation method, as applicable to companies that lack extensive historical data. The mid-point between the vesting date and the contractual expiration date is used as the expected term under this method.

Expected volatility. The Company bases its expected volatility on its own stock price history.

Risk free rate. The risk-free rate for periods within the expected term of the award is based on the interest rate of a traded zero-coupon U.S. Treasury bond with a term equal to the awards' expected term on the date of grant.

Dividend yield. The Company has not paid and does not expect to pay dividends in the foreseeable future. Accordingly, the assumed dividend yield is zero.

Restricted Shares and Restricted Stock Units Granted to Employees

Restricted shares and restricted stock units are referred to collectively as restricted stock. The following table summarizes the Company's restricted share and restricted stock unit activity for the three months ended March 31, 2016:



	Nonvested Restricted Shares and Restricted Stock Units		Weighted-Average Grant Date Fair Value
Balance outstanding at December 31, 2015	21,480,364		$	4.17
Granted	7,410,814		3.47
Vested	(2,851,670	)	4.00
Canceled	—		—
Forfeited	(79,182	)	3.85
Balance outstanding at March 31, 2016 (1)	25,960,326		$	3.99

(1) Performance linked restricted stock units of 1,925,750 were awarded to employees of the Company in December 2013 and January 2014. An additional 2,800,000 performance linked restricted stock units were awarded in March 2016. Of the awards granted, 326,250 have been forfeited through March 31, 2016. The remaining awards, included in the outstanding balance as of March 31, 2016, will vest between March 2019 and December 2020 and will be earned only to the extent that the Company attains specified market goals relating to its volume-weighted average share price and total shareholder return in relation to certain benchmark indices and performance goals relating to aggregate net income and average return on shareholder equity. The actual number of RSUs ultimately earned could vary from zero, if performance goals are not met, to as much as 150% of the targeted award. Each RSU is equal to the one share of the Company’s Class A common stock. Compensation expense is recognized to the extent that it is probable that the Company will attain the performance goals.

The fair value of restricted stock (excluding performance linked units which are valued using the Monte Carlo valuation model) is determined based on the number of shares granted and the quoted price of the Company's common stock on the date of grant.

As of March 31, 2016, there was $79.4 million of unrecognized compensation expense related to the Company's grant of nonvested restricted shares and restricted stock units to employees. Unrecognized compensation expense related to nonvested restricted shares and restricted stock units granted to employees is expected to be recognized over a weighted-average period of 2.95 years.

Restricted Shares and Restricted Stock Units Granted to Non-employee Board Members

There were no restricted stock units awarded during the three months ended March 31, 2016. As of March 31, 2016 there were 497,570 restricted stock units outstanding.
