| Weighted-average fair value of options granted and the weighted-average assumptions used in the Black Scholes Merton option pricing model for such grants |
The weighted-average fair value of stock options granted during the years ended December 31, 2022, 2021 and 2020 and the weighted-average assumptions used in the Black-Scholes-Merton option-pricing model for such grants were as follows:
1The dividend yield is the calculated yield on the closing market price per share of the Company’s stock on the grant date.
2The expected volatility is based on implied volatilities from traded options on the Company’s stock, historical volatility of the Company’s stock and other factors.
3The risk-free interest rate for the period matching the expected term of the stock options is based on the U.S. Treasury yield curve in effect on the grant date.
4The expected term of the stock options represents the period of time that stock options are expected to be outstanding and is derived by analyzing historical exercise behavior.
