Compensation expense related to stock options and restricted stock awards recognized in operating results (general and administrative expenses) was approximately $0.6 million and $0.5 million for the three months ended June 30, 2015 and June 30, 2014, respectively, and approximately $1.7 and $1.1 million for the six months ending June 30, 2015 and June 30, 2014, respectively.

The following assumptions were used to value stock options calculated using the Black-Scholes options pricing model:

	Six months ended June 30,
	2015		2014
Dividend yield	0	%	0	%
Expected volatility	60.72	%	52.8	%
Risk-free interest rate	1.9	%	1.0	%
Expected life	3.5 years		3.5 years

Exercisable at June 30, 2015	643,927		$	3.48	2.34	$	—

The total intrinsic value of options exercised during the six months ended June 30 , 2015 and 2014 were approximately $0 and $1.0 million respectively.

As of June 30, 2015 total unrecognized stock-based compensation expense related to non-vested stock options was approximately $2.9 million, which we expect to recognize over a weighted average period of 2.0 years.

Restricted Shares

Restricted share activity for the six months ended June 30, 2015 was as follows:

	Shares		Weighted Average Fair Value

Outstanding at December 31, 2014	689,370		$	2.87
Granted	521,322		1.11
Vested	(697,630	)	1.79
Forfeited	(27,817	)	3.36

Outstanding at June 30, 2015	485,245		$	2.50

Restricted stock awards for executive officers and employees generally vest ratably over three years. Fair value of our restricted shares is based on our closing stock price on the date of grant. As of June 30, 2015, total unrecognized stock-based compensation expense related to non-vested restricted shares was $0.9 million, which is expected to be recognized over a weighted average period of approximately 1.7 years.
