Share-based Compensation

Share-Based Compensation

Stock Options—The Company accounts for compensation expense associated with stock options issued to employees, Directors, and non-employees based on their fair value, which is calculated using an option pricing model, and is recognized over the service period, which is usually the vesting period. At December 31, 2019, the Company had two equity based compensation plans. No stock options were granted to employees or non-employees during 2019, 2018, and 2017; however, options were granted to Directors in 2019, 2018, and 2017. Stock compensation expense of $537 thousand, $449 thousand and $433 thousand was recognized during the years ending December 31, 2019, 2018, and 2017, respectively, on outstanding and unvested options.

The fair value of options granted during 2019 is estimated on the date of grant using a Black-Scholes option pricing model. The following table includes the weighted- average assumptions used in estimating the fair values and the resulting weighted-average fair value of stock options granted in the periods presented:

	Year Ended December 31,
	2019			2018			2017
Weighted average fair values of stock options granted	$	12.68		$	11.80		$	15.38
Expected volatility	36.0		%	35.7		%	37.9		%
Expected dividends	.65		%	.70		%	.56		%
Weighted average risk-free interest rate	1.72		%	2.47		%	1.64		%
Expected life of stock options (in years)	3.5			3.5			3.5

A summary of stock option activity for the years ended December 31, 2019, 2018, and 2017 is as follows:

The aggregate intrinsic value for stock options outstanding and exercisable is defined as the difference between the market value of the Company’s stock as of the end of the period and the exercise price of the stock options. The total intrinsic value of stock options exercised during 2019, 2018, and 2017 was zero, $900 thousand, and $169 thousand, respectively.

Cash received or the value of stocks canceled from option exercises under all share-based payment arrangements for the years ended December 31, 2019, 2018, and 2017, was zero, $439 thousand and $52 thousand, respectively.

Restricted Stock—Pursuant to the Company’s restricted stock agreements, the restricted stock granted generally vests as follows: one third after one year, and the remaining in eight equal quarterly installments. The restricted stock also vests with respect to any unvested shares upon the applicable employee’s death, disability or retirement, the Company’s termination of the employee other than for cause, or for a change in control of the Company. A summary of the status of the Company’s non-vested restricted stock grant shares is presented in the following table:
