Stock-Based Compensation

 

The Company issues service, performance and market-based stock options to employees and non-employees. The Company estimates the fair value of service and performance stock option awards using the Black-Scholes option pricing model. The Company estimates the fair value of market-based stock option awards using a Monte-Carlo simulation. Compensation expense for stock option awards is amortized on a straight-line basis over the awards’ vesting period. Compensation expense includes the impact of forfeitures as they are incurred.

 

The expected term of the stock options represents the average period the stock options are expected to remain outstanding and is based on the expected term calculated using the approach prescribed by the Securities and Exchange Commission's Staff Accounting Bulletin No. 110 for “plain vanilla” options. The expected stock price volatility for the Company’s stock options was determined by using an average of the historical volatilities of the Company. The Company will continue to analyze the stock price volatility and expected term assumptions as more data for the Company’s common stock and exercise patterns become available. The risk-free interest rate assumption is based on the U.S. Treasury instruments whose term was consistent with the expected term of the Company’s stock options. The expected dividend assumption is based on the Company’s history and expectation of dividend payouts.

 

The Company estimated the fair value of employee and non-employee stock options using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service periods of the respective awards. The fair value of employee stock options was estimated using the following weighted-average assumptions: 

               
    Year Ended March 31,  
    2023     2022  
Fair value of the Company’s common stock on date of grant   $ 1.09     $ 4.60  
Expected term     6.00 yrs       6.00 yrs  
Risk-free interest rate     3.92%       1.60%  
Dividend yield     0.00%       0.00%  
Volatility     110.88%       123.27%  
Fair value of options granted   $ 0.92     $ 4.03  

  

Share-based awards compensation expense is as follows: 

               
    Year Ended March 31,  
    2023     2022  
Cost of revenues   $     $  
Research and development            
Selling, general and administrative     669,000       382,000  
Total stock-based compensation   $ 669,000     $ 382,000  

 

At March 31, 2023, there were unrecognized compensation costs of $562,000 related to stock options which is expected to be recognized over a weighted-average amortization period of 1.83 years.

  

A tax benefit of $20,000 has been recognized relating to stock-based compensation as a result of non-qualified stock options and restricted stock exercised during the year ending March 31, 2023. In addition, the stock-based compensation deferred tax asset has been increased by $102,000 primarily related to the expiration of stock compensation grants.
