Share-Based Payment Arrangement [Abstract] |
Stock-Based and Other Long-Term Incentive Compensation | Stock-Based and Other Long-Term Incentive Compensation Restricted Stock On June 20, 2019, at our annual meeting of shareholders, our shareholders approved an Equity Incentive Plan for restricted shares/units, stock options and other equity awards. The Equity Incentive Plan allows issuance up to 500,000 shares of common stock. On June 16, 2022, at our annual meeting of shareholders, our shareholders approved an amendment to the Equity Incentive Plan to increase the number of shares available for issuance under the plan by 650,000 shares of common stock. As of December 31, 2022, we had 250,847 shares outstanding under the Equity Incentive Plan that will vest over the next three years. As of December 31, 2022, 570,473 shares were still available for issuance under the Equity Incentive Plan. On April 26, 2022, 4,212 shares of restricted common stock were awarded to each of our four independent Board members. The restricted stock issued to our directors vests in one year from the date of grant. On August 15, 2022, the Compensation Committee awarded 32,040 shares of restricted common stock to two executive officers that vest ratably over three years, beginning on April 25, 2023. In addition, on August 15, 2022, the Compensation Committee awarded 60,839 shares of restricted common stock to Mr. Stephen Taylor, our Interim Chief Executive Officer. The restricted shares granted to Mr. Taylor will vest in full on June 30, 2023. Compensation expense related to the restricted shares was approximately $1.7 million and $1.7 million for the years ended December 31, 2022 and 2021, respectively. As of December 31, 2022, there was a total of approximately $1.0 million of unrecognized compensation expense related to the unvested portion of these restricted shares/units. This expense is expected to be recognized over the next three years. A summary of all restricted stock activity as of December 31, 2021 and 2022 and changes during the years then ended are presented below.

Other Long-Term Incentive Compensation On April 28, 2020, the Compensation Committee issued a long-term incentive award of $1.1 million to an executive officer that vests in equal, annual tranches over three years. At the time of vesting, each tranche will be payable in cash or common stock at the discretion of the Compensation Committee. On March 18, 2021, the Compensation Committee issued a long-term incentive award of $1.0 million to an executive officer that vests in equal, annual tranches over three years. On March 18, 2021, we issued a $50,000 award to each of our three independent Board members. On April 1, 2021, we issued a $50,000 award to a newly appointed independent Board member. These awards vest one year from the date of grant and are payable in cash upon vesting. On April 26, 2022, we issued a $50,000 award to each of our four independent Board members. These awards vest one year from the date of grant and are payable in cash upon vesting. The Company accounts for these other long-term incentive awards as liabilities under accrued liabilities on our condensed consolidated balance sheet. The vesting of these awards is subject to acceleration upon certain events, such as (i) death or disability of the recipient, (ii) certain circumstances in connection with a change of control of the Company, (iii) for executive officers, termination without cause (as defined in the agreement), and (iv) for executive officers, resignation for good reason (as defined). Total compensation expense related to these other long-term incentive awards was approximately $1.0 million for the year ended December 31, 2022. As of December 31, 2022 there was a total of $0.7 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next year. Stock Option Plan Our Stock Option Plan, which is stockholder approved, permits the granting of stock options to its employees for up to 1.0 million shares of common stock. We believe that such awards align the interests of our employees with our stockholders. Option awards are generally granted with an exercise price equal to the market price of our stock at the date of grant; those option awards generally vest in equal increments over three years of continuous service and have ten-year contractual terms. Certain option and share awards provide for accelerated vesting if there is a change in control of the Company (as defined in the Stock Option Plan). The last date that grants can be made under the Stock Option Plan is February 28, 2026. As of December 31, 2022, 344,253 shares were still available to be granted under the Stock Option Plan. The fair value of each option award is estimated on the date of grant using the Black-Scholes option valuation model that uses the assumptions noted in the following table. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life of options granted is based on the vesting period and historical exercise and post-vesting employment termination behavior for similar grants. We use historical data to estimate option exercise and employee termination within the valuation model; separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes.
Weighted average Black -Scholes fair value assumption during the year ended December 31, are as follows: |  | 2022 |  |
Risk free rate |  |  | 2.99 | % |  |  |  |
Expected life |  |  | 2.67 |  |  |  |
Expected volatility |  |  | 54.5 | % |  |  |  |
Expected dividend yield |  |  | — | % |  |  |  |
During the year ended December 31, 2022, 215,000 stock option grants were made. A summary of all option activity as of December 31, 2021 and 2022 and changes during the years then ended are presented below:
