Determination of the Fair Value of Stock-based Compensation Grants

We calculate the fair value of stock-based compensation arrangements using the Black-Scholes option-pricing model. The Black-Scholes option-pricing model requires the use of subjective assumptions, including volatility of our common stock, the expected term of our stock options, the risk free interest rate for a period that approximates the expected term of our stock options, and the fair value of the underlying common stock on the date of grant. In applying these assumptions, we considered the following factors:

55

•we estimate expected volatility based on the volatility of our own common stock trading history and implied volatility;

•the assumed dividend yield is based on our expectation of not paying dividends on our underlying common stock for the foreseeable future;

•we determine the average expected life of stock options based on the simplified method in accordance with SEC Staff Accounting Bulletin Nos. 107 and 110. We expect to use the simplified method until we have sufficient historical exercise data to provide a reasonable basis upon which to estimate expected term;

•we determine the risk-free interest rate by reference to implied yields available from U.S. Treasury securities with a remaining term equal to the expected life assumed at the date of grant; and

•we recognize forfeitures as they are incurred.

The assumptions used in the Black-Scholes option-pricing model for the years ended December 31, 2024 and 2023 are set forth below:
