Stockholders' Equity Note [Abstract] |
Shareholders' Equity | Stock-Based Compensation. The Company’s stock-based compensation plans are administered by the Compensation Committee of the Board of Directors, which, subject to approval by the Board of Directors, selects persons to receive awards and determines the number of shares subject to each award and the terms, conditions, performance measures and other provisions of the award. The following table summarizes the stock-based compensation expense that was recognized in the Company’s statements of operations for the years ended December 31, 2020 and 2019:
Year ended December 31 |  | 2020 |  |  | 2019 |
Cost of sales |  | $ | 5,000 |  |  | $ | 14,000 |
Selling |  |  | 38,000 |  |  |  | 121,000 |
Marketing |  |  | (1,000 | ) |  |  | 12,000 |
General and administrative |  |  | 130,000 |  |  |  | 275,000 |
|  | $ | 172,000 |  |  | $ | 422,000 |
The Company uses the Black-Scholes option pricing model to estimate fair value of stock-based awards with the following weighted average assumptions:
|  | 2020 |  |  | 2019 |
Stock Purchase Plan Options: |  |  |  |  |  |
Expected life (years) |  |  | 1.0 |  |  |  | 1.0 |
Expected volatility |  |  | 59 | % |  |  | 57 | %
Dividend yield |  |  | 0 | % |  |  | 0 | %
Risk-free interest rate |  |  | 1.6 | % |  |  | 2.6 | %
The Company uses the graded attribution method to recognize expense for unvested stock-based awards. The amount of stock-based compensation recognized during a period is based on the value of the awards that are ultimately expected to vest. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company re-evaluates the forfeiture rate annually and adjusts it as necessary. Stock Options, Restricted Stock, Restricted Stock Units, and Other Stock-Based Compensation Awards. The Company maintains the 2003 Incentive Stock Option Plan (the “2003 Plan”), the 2013 Omnibus Stock and Incentive Plan (the “2013 Plan”) and the 2018 Equity Incentive Plan (the “2018 Plan”). The 2018 Plan replaced the 2013 Plan upon its ratification by shareholders in July 2018. No further awards may be granted under the 2013 Plan or the 2003 Plan. Awards granted under the 2003 Plan and 2013 Plan will remain in effect until they are exercised or expire according to their terms. Under the terms of the 2018 Plan, the number of shares of our common stock that may be the subject of awards and issued under the 2018 Plan was initially 128,571 plus any shares remaining available for future grants under the 2013 Plan on the effective date of the 2018 Plan. All equity awards made during 2019 were under the 2018 Plan. Under the terms of the 2018 Plan, the Company may grant awards in a variety of instruments including stock options, restricted stock and restricted stock units to employees, consultants and directors generally at an exercise price at or above 100% of fair market value at the close of business on the date of grant. Stock options expire 10 years after the date of grant and generally vest over three years. The Company issues new shares of common stock upon grant of restricted stock, when stock options are exercised, and when restricted stock units are vested and/or settled.
