Stock Option |
Stock Options | NOTE 9 - Stock Options The Company follows ASC 718 (“Share-Based Payment”), which requires that all share-based payments to employees, including stock options, be recognized as compensation expense in the consolidated financial statements based on their fair values and over the requisite service period. For the fiscal years ended June 30, 2022, 2021 and 2020, the Company recorded non-cash compensation expense of $1,649,000, $435,000 and $583,000, respectively, relating to stock-based compensation. 2012 Employee Stock Option Plan In December 2012, the stockholders approved the 2012 Employee Stock Option Plan (the 2012 Employee Plan). The 2012 Employee Plan authorizes the granting of awards, the exercise of which would allow up to an aggregate of 1,900,000 shares of the Company’s common stock to be acquired by the holders of such awards. Under this plan, the Company may grant stock options, which are intended to qualify as incentive stock options (ISOs), to valued employees. Any plan participant who is granted ISOs and possesses more than 10% of the voting rights of the Company’s outstanding common stock must be granted an option with a price of at least 110% of the fair market value on the date of grant. Under the 2012 Employee Plan, stock options may be granted to valued employees with a term of up to 10 years at an exercise price equal to or greater than the fair market value on the date of grant and are exercisable, in whole or in part, at 20% per year beginning on the date of grant. An option granted under this plan shall vest in full upon a “change in control” as defined in the plan. At June 30, 2022, 523,080 stock options were outstanding, 176,752 stock options were exercisable and 1,138,920 stock options were available for grant under this plan. 338,000 options were granted under this plan during the year ended June 30, 2022. The fair value of each option granted was estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 |  | 2021 |  | 2020 |
Risk-free interest rates | ​ | 1.64 | % | n/a | % | .6% - 2.10 | %
Expected lives | ​ | 6.18 Years | ​ | n/a | ​ | 10 years | ​
Expected volatility | ​ | 43 | % | n/a | % | 44% - 46 | %
Expected dividend yields | ​ | 0 | % | n/a | % | 0 | %
​ The Company uses a weighted-average expected stock-price volatility assumption that is a combination of both current and historical implied volatilities of the underlying stock. The implied volatilities were obtained from publicly available data sources. For the weighted-average expected option life assumption, the Company considers the exercise behavior of past grants. The average risk-free interest rate is based on the U.S. Treasury Bond rate for the expected term of the options and the average dividend yield is based on historical experience. The following table reflects activity under the 2012 Plan for the fiscal years ended June 30,: ​
