STOCK-BASED COMPENSATION

NOTE 6 – STOCK-BASED COMPENSATION

Stock Incentive Plans

Options

We have one long-term equity incentive plan which we refer to as the 2006 Equity Incentive Plan, which we first amended and restated as of April 20, 2015 and again on March 9, 2017 (“the Restated Plan”). The Restated Plan was approved by our stockholders at our annual stockholders meeting on June 8, 2017. We have reserved for issuance under the 2017 Restated Plan 14,000,000 shares of common stock. We can issue options, stock awards, stock appreciation rights, stock units and cash awards under the 2017 Restated Plan. Certain options granted under the Restated Plan to employees are intended to qualify as incentive stock options under existing tax regulations. Stock options generally vest over three to five years and expire three to ten years from the date of grant.

As of March 31, 2018, we had outstanding options to acquire 553,282 shares of our common stock, of which options to acquire 100,211 shares were exercisable. The following summarizes all of our option transactions for the three months ended March 31, 2018:

Outstanding Options Under the 2006 Plan		Shares				Weighted Average Exercise price Per Common Share				Weighted Average Remaining Contractual Life (in years)				Aggregate Intrinsic Value

Balance, December 31, 2017			420,149			$	6.82
Granted			133,133				10.05
Balance, March 31, 2018			553,282				7.05				7.95			$	3,487,601
Exercisable at March 31, 2018			100,211				4.39				4.53				1,003,291

Aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between our closing stock price on March 31, 2018 and the exercise price, multiplied by the number of in-the-money options as applicable) that would have been received by the holder had all holders exercised their options on March 31, 2018. No options were exercised during the three months ended March 31, 2018. As of March 31, 2018, total unrecognized stock-based compensation expense related to non-vested employee awards was $1.4 million which is expected to be recognized over a weighted average period of approximately 3.0 years.

Restricted Stock Awards (“RSA’s”)

The Restated Plan permits the award of restricted stock awards (“RSA’s”). As of March 31, 2018, we have issued a total of 5,408,161 RSA’s of which 284,234 were unvested at March 31, 2018. The following summarizes all unvested RSA’s activities during the three months ended March 31, 2018:

						Weighted- Average
						Remaining				Weighted-
						Contractual				Average
		RSA's				Term (Years)				Fair Value
RSA's unvested at December 31, 2017			447,351							$	6.17
Changes during the period
Granted			462,701							$	10.13
Vested			(625,818	)						$	6.03
RSA's unvested at March 31, 2018			284,234				1.03			$	8.93

We determine the fair value of all RSA’s based of the closing price of our common stock on award date.

Other stock bonus awards

The Restated Plan also permits the award of stock bonuses not subject to any future service period. These awards are valued and expensed based on the closing price of our common stock on the date of award. During the three months ended March 31, 2018 we issued no shares relating to these awards.

Plan summary

In summary, of the 14,000,000 shares of common stock reserved for issuance under the Restated Plan, at March 31, 2018, we had issued 13,790,993 total shares between options, RSA’s and other stock awards. With options cancelled and RSA’s forfeited amounting to 3,140,009 and 59,053 shares, respectively, there remain 3,408,069 shares available under the Restated Plan for future issuance.
