Fair Value of Option on Date of Grant

The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model in order to measure the compensation cost associated with the award. This model incorporates certain assumptions for inputs including a risk-free interest rate, expected dividend yield of the underlying Common Stock, expected option life and expected volatility in the market value of the underlying Common Stock. The following assumptions were used for options issued in the following periods:

		2019		2018		2017
Expected volatility		N/A		N/A		33%
Weighted-average expected volatility		N/A		N/A		33%
Expected lives		N/A		N/A		3 years
Risk-free interest rate		N/A		N/A		1.49−1.93%
Expected dividend yield		none		none		none
