Stock Based Compensation

In May 2017, the Company’s stockholders approved the 2017 Plan, with such stockholder action resulting in the termination of the Company’s 2010 Stock Incentive Plan (the “2010 Plan”). The terms of the 2017 Plan are substantially the same as the 2010 Plan. However, any outstanding awards under the 2010 Plan will continue in accordance with the terms of the 2010 Plan and any award agreement executed in connection with such outstanding awards. At June 30, 2018, there were 217,163 shares of non-vested restricted stock outstanding under the 2010 Plan.

Pursuant to the 2017 Plan, eligible employees, officers and directors of the Company are offered the opportunity to acquire the Company's common stock through the award of restricted stock and other equity awards under the 2017 Plan. The maximum number of shares that may be issued under the 2017 Plan is 5,570,000. Of the common stock authorized at June 30, 2018, 4,237,065 shares are available for issuance under the 2017 Plan. The Company’s non-employee directors have been issued 131,975 shares under the 2017 Plan as of June 30, 2018. The Company’s employees have been issued 209,264 of restricted stock under the 2017 Plan as of June 30, 2018. At June 30, 2018, there were 207,178 shares of non-vested restricted stock outstanding and 991,696 common shares reserved for issuance in connection with outstanding PSUs under the 2017 Plan.


(a)	Restricted Common Stock Awards

During the three and six months ended June 30, 2018, the Company recognized non-cash compensation expense on its restricted common stock awards of $0.3 million and $0.6 million, respectively. During the three and six months ended June 30, 2017, the Company recognized non-cash compensation expense on its restricted common stock awards of $0.4 million and $0.7 million, respectively. Dividends are paid on all restricted common stock issued, whether those shares have vested or not. In general, non-vested restricted stock is forfeited upon the recipient's termination of employment.

A summary of the activity of the Company's non-vested restricted stock collectively under the 2010 Plan and 2017 Plan for the six months ended June 30, 2018 and 2017, respectively, is presented below:



	2018				2017
	Number of Non-vested Restricted Shares		Weighted Average Per Share Grant Date Fair Value ⁽¹⁾		Number of Non-vested Restricted Shares		Weighted Average Per Share Grant Date Fair Value ⁽¹⁾
Non-vested shares at January 1	422,928		$	6.36	319,058		$	6.40
Granted	206,597		5.57		332,921		6.54
Vested	(200,064	)	6.55		(150,209	)	6.74
Forfeited	(5,120	)	6.25		—		—
Non-vested shares as of June 30	424,341		5.90		501,770		6.39
Weighted-average of restricted stock granted during the period	206,597		$	5.57	332,921		$	6.54


⁽¹⁾	The grant date fair value of restricted stock awards is based on the closing market price of the Company’s common stock at the grant date.

At June 30, 2018 and 2017, the Company had unrecognized compensation expense of $2.1 million and $2.7 million, respectively, related to the non-vested shares of restricted common stock under the 2010 Plan and 2017 Plan. The unrecognized compensation expense at June 30, 2018 is expected to be recognized over a weighted average period of 2.1 years. The total fair value of restricted shares vested during the six months ended June 30, 2018 and 2017 was approximately $1.1 million and $1.0 million, respectively. The requisite service period for restricted shares at issuance is three years.


(b)	Performance Share Awards

In May 2015, the Compensation Committee of the Board of Directors approved a PSA under the 2010 Plan to the Company’s Chairman and Chief Executive Officer. At the time of grant, the target number of shares pursuant to the PSA consisted of 89,629 shares of common stock. The PSA had a grant date fair value of approximately $0.4 million. The grant date fair value of the PSA was determined through a Monte-Carlo simulation of the Company’s common stock total shareholder return and the common stock total shareholder return of its peer companies to determine the total shareholder return of the Company’s common stock relative to its peer companies over a future period of three years. For the PSA granted in 2015, the inputs used by the model to determine the fair value were (i) historical stock return volatilities of the Company and its peer companies over the most recent three year period, (ii) a risk free rate based on the three year U.S. Treasury rate on grant date, and (iii) historical pairwise stock return correlations between the Company and its peer companies over the most recent three year period.

Under the terms of the agreement pursuant to which the PSA was granted, vesting of the PSA would occur at the end of three years based on three-year total shareholder return in April 2018. As of June 30, 2018, no shares were issued under the PSA award.


(c)	Performance Stock Units

During the six months ended June 30, 2018, the Compensation Committee and the Board of Directors approved the grant of PSUs to the Chief Executive Officer, Chief Financial Officer and certain other employees as part of our 2018 Long-Term EIP. The awards were issued pursuant to and are consistent with the terms and conditions of the 2017 Plan.

The PSU awards are subject to performance-based vesting under the 2017 Plan pursuant to the PSU Agreements. At the time of grant, the target number of shares pursuant to the PSU awards totaled 653,365 shares of common stock. The PSU awards had a grant date fair value of approximately $2.7 million. Vesting of the PSUs will occur at the end of three years based on the following:


•	If three-year TSR performance relative to the Company's identified performance peer group (the "Relative TSR") is less than 30^th percentile, then 0% of the target PSUs will vest;


•	If three-year Relative TSR performance is equal to the 30^th percentile, then Threshold % (as defined in the individual PSU Agreements) of the target PSUs will vest;


•	If three-year Relative TSR performance is equal to the 50^th percentile, then 100% of the target PSUs will vest; and


•	If three-year Relative TSR performance is greater than or equal to the 80^th percentile, then Maximum % (as defined in the individual PSU Agreements) of the target PSUs will vest.

The percentage of target PSUs that vest for performance between the 30^th, 50^th, and 80^th percentiles will be calculated using linear interpolation.

Total shareholder return for the Company and each member of the peer group will be determined by dividing (i) the sum of the cumulative amount of such entity’s dividends per share for the performance period and the arithmetic average per share volume weighted average price (the “VWAP”) of such entity’s common stock for the last thirty (30) consecutive trading days of the performance period minus the arithmetic average per share VWAP of such entity’s common stock for the last thirty (30) consecutive trading days immediately prior to the performance period by (ii) the arithmetic average per share VWAP of such entity’s common stock for the last thirty (30) consecutive trading days immediately prior to the performance period. Each PSU represents an unfunded promise to receive one share of the Company's common stock once the performance condition has been satisfied.

The grant date fair value of the PSUs was determined through a Monte-Carlo simulation of the Company’s common stock total shareholder return and the common stock total shareholder return of its identified performance peer companies to determine the Relative TSR of the Company’s common stock over a future period of three years. For the PSUs granted in 2018, the inputs used by the model to determine the fair value are (i) historical stock price volatilities of the Company and its identified performance peer companies over the most recent three year period and correlation between each company's stock and the identified performance peer group over the same time series and (ii) a risk free rate for the period interpolated from the U.S. Treasury yield curve on grant date.

Compensation expense related to the PSUs was $0.2 million and $0.2 million for the three and six months ended June 30, 2018, respectively. As of June 30, 2018, there was $2.4 million of unrecognized compensation cost related to the non-vested portion of the PSUs.
