Stock-Based Compensation

Note 9. Stock-Based Compensation

We have two incentive plans – the 2012 Stock Incentive Plan (“2012 Plan”) and the 2019 Stock Incentive Plan (“2019” Plan”). As of June 30, 2020, shares available for future grants totaled 2,730,169. Stock options granted during 2020 under the 2012 Plan totaled 319,669. No shares remain available for issuance under the 2012 Plan. The following is a summary of stock-based compensation expense, net of forfeitures, included in General and administrative expenses in the Condensed Consolidated Statements of Income ($ in thousands):

	Three Months Ended				Six Months Ended

	2020		2019		2020		2019
Non-cash stock-based compensation expense	$	470	$	477	$	2,315	$	2,478

The weighted average fair value of options granted during the six months ended June 30, 2020 and 2019 was $5.57 and $6.17 per option, respectively. The fair value of each grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:

	2020	2019
Dividend yield	5.1%	5.5%
Expected volatility	17.1%	18.6%
Expected lives	2.9 years	2.9 years
Risk-free interest rate	1.30%	2.50%
