Under the Company’s current 2015 Stock Incentive Plan (the “2015 Plan”), the Company’s Board of Directors has flexibility to determine the type and amount of awards to be granted to eligible participants, who must be employees, directors, officers or consultants of the Company or its subsidiaries. The 2015 Plan allows for grants of incentive stock options, nonqualified stock options, restricted stock awards, stock appreciation rights, and restricted units. The aggregate number of shares of common stock that may be granted through awards under the 2015 Plan to any employee in any calendar year may not exceed 500 shares. The 2015 Plan will continue in effect until December 2025 unless terminated sooner. 

Options Granted:

During the nine months ended September 30, 2020, the Company issued stock options for an aggregate of 613 shares under the 2015 Plan to directors and employees of the Company. Of the 613 options issued, 38 options vest in four equal consecutive quarterly tranches from the date of grant. 145 options issued vest in four equal annual tranches beginning December 31, 2020. 50 options issued vest in five equal annual tranches beginning December 31, 2020. 30 options issued vest in three equal annual tranches beginning December 31, 2020. The remaining 350 options issued vest in three equal annual tranches beginning August 27, 2021.

For computing the fair value of the stock-based awards, the fair value of each option grant has been estimated as of the date of grant using the Black-Scholes option-pricing model with the following assumptions:

(a)Expected volatility is based upon the Company’s historical volatility.

(b)The expected term was determined based upon the underlying terms of the awards and the category and employment history of employee award recipient.

The grant date fair value of the stock options granted during the nine months ended September 30, 2020 was $2,581, which will be recognized over the vesting period of the options.

Stock Award Granted:

On September 14, 2020, the Company issued and granted to the Executive Chairman a stock award of 244 shares under the 2015 Plan which vested immediately. The fair value of the stock award was calculated as of the date of grant using the closing market price. The grant date fair value of the stock award granted during the nine months ended September 30, 2020 was $3,314, which was recognized immediately.

Market Condition Restricted Shares Granted:

On August 27, 2020, the Company issued and granted to an employee a restricted stock award of 100 restricted shares under the 2015 Plan, of which 100 restricted shares will vest if, on or before August 27, 2023, the Fair Market Value (as defined in the Plan) of the Company’s common stock shall have equaled or exceeded $15.00 per share for twenty consecutive trading days. For computing the fair value of the 100 restricted shares with a market condition, the fair value of the restricted stock award grant has been estimated as of the date of grant using the Monte-Carlo pricing model with the assumptions below.

Using these assumptions, the fair value of the market condition restricted stock award granted on August 27, 2020 was $991.

The total non-cash stock compensation expense related to restricted stock, stock options and stock awards recorded by the Company for the three months ended September 30, 2020 and 2019 was $4,204 and $678, respectively, and for the nine months ended September 30, 2020 and 2019 was $5,433 and $2,246, respectively. For the three and nine months ended September 30, 2020 and 2019, the majority of stock-based compensation costs were classified as selling, general and administrative expenses.

As of September 30, 2020, there were 1,744 unvested stock options and unrecognized compensation cost of $5,354 related to unvested stock options, as well as 600 unvested restricted stock awards and unrecognized compensation costs of $3,119 related to unvested restricted stock awards.
