Schedule of valuation assumptions |
Management has valued stock options at their date of grant utilizing the Black‑Scholes‑Merton Option pricing model. The fair value of the underlying shares was determined by the market value of stock of similar companies and recent arm’s length transactions involving the sale of the Company’s common stock. Prior the Merger, the Company lacked company-specific historical and implied volatility information for its common stock. Therefore, the expected volatility was calculated using the historical volatility of a comparative public traded companies. The following table presents the assumptions used on recent dates on which options were granted by the Company.
