Stock-based compensation expense for stock-based compensation awards granted is based on the grant-date fair value. For stock option awards, the fair value is estimated at the date of grant using the Black-Scholes-Merton valuation model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. The fair value of each option granted is estimated on the date of grant using the Black-Scholes-Merton model based on the weighted-average assumptions for expected dividend yield, expected stock price volatility, risk-free interest rate and expected life of options granted.

 

The assumptions used in determining the fair value of and stock option grants were as follows:

 

		2018				2017				2016
Expected price volatility			35.39	%			29.00	%			29.00	%
Expected dividend yield			1.24	%			0.44	%			0.64	%
Expected term (in years)			6				6				6
Risk-free rate			2.90	%			2.08	%			1.85	%

 

The weighted average grant-date fair value of options granted during the years ended and was and respectively.
