The
Company estimates the fair value of each stock option on the grant date using the Black-Scholes-Merton valuation model, which requires
several estimates including an estimate of the fair value of the underlying common stock on grant date. The expected volatility was based
on an average of the historical volatility of the Company. The expected term was contractual life of option. The risk-free interest rate
was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. The Company did not grant
any stock options during the first quarter of 2023.
Of
the 60 options outstanding as of June 30, 2024, 18 were awarded to non-executive members of the board of directors.
