Share-based Payment Arrangement [Abstract] |
Stock-Based and Other Long-Term Incentive Compensation | Stock-Based and Other Long-Term Incentive Compensation Restricted Stock/Units On June 18, 2014, at our annual meeting of shareholders, our shareholders approved a proposed amendment to the 2009 Restricted Stock/Unit Plan (the "2009 Plan") to add additional 500,000 shares of common stock to the Plan, thereby authorizing the issuance of up to 800,000 shares of common stock under the Plan. The 2009 Plan expired on June 16, 2019. At December 31, 2020 we had 34,899 shares outstanding under the 2009 Plan that will vest over the next one year. On June 20, 2019, at our annual meeting of shareholders, our shareholders approved a new proposed Equity Incentive Plan for restricted shares/units and stock options. The Equity Incentive Plan allows issuance up to 500,000 share of common stock. As of December 31, 2020, we had 223,202 shares outstanding under the Equity Incentive Plan that will vest over the next three years. In accordance with the Company's employment agreement with Stephen Taylor, the Company's Chief Executive Officer, the Compensation Committee reviewed his performance in determining the issuance of restricted common stock. Based on this review which included consideration of the Company's 2019 performance, Mr. Taylor, was awarded 94,133 restricted shares/units on April 28, 2020, which vest over three years, in equal installments beginning April 28, 2021. On April 28, 2020, the Compensation Committee awarded 10,000 restricted shares/units to James Hazlett, our Vice President of Technical Services. The restricted shares/units to Mr. Hazlett vest over three years, in equal installments, beginning April 28, 2021. We also awarded and issued 4,432 shares of restricted common stock/units to each of our four independent Board members as partial payment for 2020 directors' fees. The restricted stock/units issued to our directors vests in one year from the date of grant. Compensation expense related to the restricted shares/units was approximately $2.2 million and $2.5 million for the years ended December 31, 2020 and 2019, respectively. As of December 31, 2020, there was a total of approximately $1.8 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. As of December 31, 2020, 200,141 shares were still available for issuance under the Equity Incentive Plan. A summary of all restricted stock/units activity as of December 31, 2019 and 2020 and changes during the years then ended are presented below.

Other Long-Term Incentive Compensation On April 28, 2020, based on its review of Mr. Taylor's 2019 performance, the Compensation Committee also issued a long-term incentive award of $1.1 million to Mr. Taylor 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. In addition, on April 28, 2020, we issued a $50,000 award to each of our four independent members of our Board of Directors as partial payment for their services in 2020. 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 to Mr. Taylor and our independent Board members 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 $0.4 million for the year ended December 31, 2020. As of December 31, 2020 there was a total of $0.8 million of unrecognized compensation expense related to these other long-term incentive awards which is expected to be recognized over the next 2.25 years. 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 under the Stock Option Plan. 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 based on 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, 2020, 384,503 shares were still available for issue 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: |  | 2020 |  |
Risk free rate |  |  | 0.48 | % |  |  |  |
Expected life |  |  | 6.59 |  |  |  |
Expected volatility |  |  | 42.33 | % |  |  |  |
Expected dividend yield |  |  | — | % |  |  |  |
