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, 2021, the Company had two equity based compensation plans. No stock options were granted to employees or non-employees during 2021, 2020, and 2019; however, options were granted to Directors in 2021, 2020, and 2019. Stock compensation expense of $539 thousand, $517 thousand and $537 thousand was recognized during the years ending December 31, 2021, 2020, and 2019, respectively, on outstanding and unvested options.
The fair value of options granted during 2021 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:
