Stock-Based Compensation Plan [Abstract] |
Stock-Based Compensation Plan | NOTE 12. STOCK-BASED COMPENSATION PLAN ﻿ Under the Company’s current 2015 Stock Incentive Plan (the “2015 Plan”), the Company’s Board of Directors (the “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. As of December 31, 2018, the number of shares authorized and reserved for issuance under the 2015 Plan is 5,743, subject to automatic annual increase equal to 5% of the total number of shares of the Company’s outstanding common stock. ﻿ Options Granted: ﻿ During the year ended December 31, 2018, the Company issued stock options for an aggregate of 1,938 shares under the 2015 Plan to directors and employees of the Company. Of the 1,938 options issued, 38 options vest in four equal consecutive quarterly tranches from the date of grant. The remaining 1,900 options issued vest in five equal tranches on December 31, 2018, 2019, 2020, 2021 and 2022. ﻿ 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: ﻿ ﻿
﻿ |  |  |  |  |  |  |  |
﻿ |  | 2018 |  | 2017 |  | 2016
﻿ |  |  |  |  |  |  |  |
﻿Number of options |  | 1,938 |  | 363 |  | 100 |  | 163
﻿Option vesting period |  | 1 - 5 Years |  | 1-2 Years |  | Immediate |  | 1-3 Years
﻿Grant price |  | $6.80 - $10.21 |  | $6.10 - $6.15 |  | $6.10 |  | $4.38 - $4.39
﻿Dividend yield |  | 0.00% - 1.09% |  | 0.00% |  | 0.00% |  | 0.00%
﻿Expected volatility (a) |  | 40.6% - 42.5% |  | 41.9% - 42.2% |  | 46.90% |  | 43.0% - 44.6%
﻿Risk-free interest rate |  | 2.65% - 3.09% |  | 1.80% |  | 1.41% |  | 1.14% - 1.23%
﻿Expected life (years) (b) |  | 5.00 - 6.50 |  | 5.31 - 5.33 |  | 2.75 |  | 5.31 - 6.00
﻿Weighted average fair value |  | $2.77 - $4.08 |  | $2.45 - $2.49 |  | $1.20 |  | $1.81 - $1.85
﻿ ﻿
| (a) |  | Expected volatility is based upon the Company’s historical volatility.
﻿
| (b) |  | Because the Company does not have sufficient historical exercise data to provide a reasonable basis upon which to estimate the expected term for these grants, the Company utilized the simplified method in developing an estimate of the expected term of these options.
﻿ ﻿ Using these assumptions, the fair value of the stock options granted during the years ended December 31, 2018, 2017, and 2016 was $6,059, $1,020, and $299, respectively, which will be amortized over the vesting period of the options. ﻿ Market Condition Restricted Shares Granted: ﻿ On June 1, 2017, the Company issued and granted to an employee a restricted stock award of 500 restricted shares under the 2015 Plan, of which (i) 250 restricted shares will vest if, on or before June 1, 2022, the Fair Market Value (as defined in the Plan) of the Company’s common stock shall have equaled or exceeded $10.00 per share for twenty consecutive trading days; and (ii) 250 restricted shares will vest if, on or before June 1, 2022, the Fair Market Value (as defined in the Plan) of the Company’s common stock shall have equaled or exceeded $12.00 per share for twenty consecutive trading days. For computing the fair value of the 500 restricted shares with a market condition, the fair value of each restricted stock award grant has been estimated as of the date of grant using the Monte-Carlo pricing model with the assumptions below. ﻿ On July 1, 2016, the Company issued and granted to an employee a restricted stock award of 100 restricted shares under the 2015 Plan, which will vest if, on or before July 1, 2020, 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 subject to a market condition, the fair value of each restricted stock award grant has been estimated as of the date of grant using the Monte-Carlo pricing model with the assumptions below. ﻿ ﻿

﻿Weighted average fair value |  | $4.30 |  | $3.68 |  | $1.05
﻿ Using these assumptions, the fair value of the market condition restricted stock awards granted on June 1, 2017 was approximately $1,995 and July 1, 2016 was approximately $105. ﻿ The total non-cash stock compensation expense related to stock options and restricted stock awards recorded by the Company was as follows: ﻿

﻿Stock options |  |  | 1,494 |  |  | 523 |  |  | 212
﻿Total |  | $ | 2,652 |  | $ | 1,181 |  | $ | 227
﻿ ﻿ For the years ended December 31, 2018, 2017, and 2016, the majority of stock-based compensation costs were classified as selling, general and administrative expense. A summary of changes in outstanding options and restricted stock awards during the year ended December 31, 2018 is as follows: ﻿ ﻿ ﻿ ﻿ ﻿ ﻿ ﻿ ﻿

The following table summarizes the exercise price range, weighted average exercise price, and remaining contractual lives by significant ranges for options outstanding and exercisable as of December 31, 2018: ﻿ ﻿

﻿ |  |  |  |  |  |  |  | Remaining Life In Years |  | Weighted Average
﻿Exercise Price Range |  | Outstanding |  | Exercisable |  | Outstanding |  | Exercisable |  | Exercise Price

﻿ |  |  | 3,956 |  |  | 2,268 |  |  | 5.7 |  |  | 5.7 |  | $ | 7.80
﻿ The intrinsic value of options exercised and restricted stock awards vested was $3,035, $28, and $18 during the years ended December 31, 2018, 2017, and 2016, respectively. Total fair value of shares vested during the years ended December 31, 2018, 2017, and 2016 was $2,833, $1,123, and $938, respectively. ﻿ The fair value of unvested restricted stock awards is determined based on the market price of our shares of common stock on the grant date or using the Monte-Carlo pricing model. As of December 31, 2018, there were 1,688 unvested stock options and unrecognized compensation cost of $5,467 related to unvested stock options, as well as 350 unvested restricted stock awards and unrecognized compensation cost of $233 related to unvested restricted stock awards. Unrecognized compensation cost of unvested stock options and restricted stock awards are expected to be recognized over the weighted average period of 3.6 years.
