STOCK-BASED COMPENSATION |
STOCK-BASED COMPENSATION | NOTE 10 — STOCK-BASED COMPENSATION On December 9, 2020, the 2020 Equity Incentive Plan (the “2020 Plan”) was approved, replacing the 2019 Equity Incentive Plan. The 2020 Plan provides for the issuance of up to 1,000,000 shares of the Company’s common stock to the Company’s employees, non-employee directors, consultants and advisors. Awards under the 2020 Plan can be granted in the form of stock options, stock appreciation rights, restricted stock, stock units, other stock-based awards and cash incentive awards. Outstanding awards issued under previous equity incentive plans will continue to be governed by their respective terms until exercised, expired or otherwise terminated or canceled, but no further equity awards will be made under those plans. The following table summarizes the stock-based compensation expense recorded for the years ended December 31, 2021 and 2020: ​

As of December 31, 2021, there was no remaining unamortized stock-based compensation expense related to warrants. Stock Options Options granted under our equity incentive plans generally have terms of five years, and typically vest and become fully exercisable ratably over three years of continuous service to the Company from the date of grant. ​ The following table summarizes the stock option activity for the years ended December 31, 2021 and 2020: ​

​ Restricted Stock Units We issue RSUs to employees, officers, directors, and consultants of the Company. The restrictions on time-based RSUs generally lapse over a one- to three-year term of continuous service from the date of grant.

​ In the third quarter of 2020, we granted 260,000 RSUs with performance-based and market-based conditions to our Chief Executive Officer (“CEO”). The performance condition for 105,000 of such RSUs is based on the achievement of Monthly Recurring Revenue (“MRR”) targets. For the years ended December 31, 2021 and 2020, we recorded $471,000 and $314,000, respectively, in stock-based compensation expense associated with 55,000 RSUs, the performance target for which achievement during the requisite period was deemed probable. The Company will continue to reassess the probability of achieving the performance conditions in future periods and record the appropriate expense if necessary. The market condition for the remaining 155,000 RSUs in the award is based on the Company’s stock price targets. The Company used a Monte Carlo simulation to determine the grant-date fair value for the market-based RSUs. The weighted-average assumptions used in the Monte-Carlo simulation were as follows: 5- year historical volatility of 136.52%, 5-year risk-free rate of 0.26%, and a performance period of 5 years. For the years ended December 31, 2021 and 2020, we recorded $1,141,000 and $1,506,000, respectively, in stock-based compensation expense related to these market-based RSUs. In the first quarter of 2021, we granted 100,000 RSUs with performance-based and market-based conditions to our CEO. The performance condition for 50,000 of such RSUs is based on the achievement of an MRR targets. The market condition for the remaining 50,000 RSUs in the award is based on a target for the Company’s stock price. The Company used a Monte Carlo simulation to determine the grant-date fair value for the market-based RSUs. The weighted-average assumptions used in the Monte-Carlo simulation were as follows: 5-year historical volatility of 116.95%, 5-year risk-free rate of 0.79%, and a performance period of 5 years. In the fourth quarter for 2021, all 100,000 RSUs were cancelled for no consideration to replenish the shares available under the 2020 Plan for additional awards to Company employees. In connection with the award cancellation, we accelerated the stock compensation expense associated with the 50,000 market-based RSUs and recognized its full grant date fair value of $1,311,000 as stock-based compensation expense in the year ended December 31, 2021.
