Stock-Based Compensation

(8) Stock-Based Compensation

The Company has a long-term incentive plan, the Amended and Restated 2001 Long-Term Incentive Plan (the “2001 Plan”). The 2001 Plan provides for stock options, restricted stock and dollar-denominated cash awards, including performance-based awards. In addition to stock options, restricted stock and cash awards, the 2001 Plan provides for the grant of stock appreciation rights, deferred stock and other stock-based awards to directors, officers, employees and consultants.

The number of shares of common stock that may be subject to outstanding awards granted under the 2001 Plan (determined immediately after the grant of any award) may not exceed 874,589 from the inception of the 2001 Plan. In addition, no individual may receive awards in any one calendar year of more than 100,000 shares of common stock. Stock options granted under the 2001 Plan expire ten years from the date of grant and generally become exercisable, or vest, immediately. Restricted stock generally vests over periods of one-half to three years. Upon the exercise of stock

options, the Company issues common stock from its non-issued authorized or treasury shares that have been reserved for issuance pursuant to the 2001 Plan. At December 31, 2020, the number of shares of common stock remaining available for future grants of stock options, restricted stock or other forms of stock-based compensation under the 2001 Plan was 120,677.

The Company recorded $1,915, $1,524 and $1,489 for stock-based compensation expense related to stock options and shares of restricted stock for 2020, 2019 and 2018, respectively. The amounts included in cost of revenues were $312, $170 and $154 and in selling, general and administrative expense were $1,603, $1,354, and $1,335, for 2020, 2019 and 2018, respectively.

There were no non-vested stock options at December 31, 2020, and the weighted-average remaining contractual life of the outstanding and exercisable stock options at such date was 6.74 years. The total compensation cost not yet recognized for restricted stock at December 31, 2020 was $1,699, which will be recognized over the weighted average of 1.07 years.

The fair value for the stock options was estimated at the date of grant using a lattice-based option valuation model, with the following weighted-average assumptions for the 2020, 2019 and 2018 grants: risk-free interest rates of 0.37% to 0.53% (weighted average 0.42%) in 2020, 1.69% to 2.33% (weighted average 1.89%) in 2019 and 2.51% to 2.80% (weighted average 2.59%) in 2018; a dividend yield of 0.56% to 0.80% (weighted average 0.64%) in 2020, 0.60% to 0.67% (weighted average 0.62%) in 2019 and 0.73% to 0.76% (weighted average of 0.75%) in 2018; and a volatility factor of .346 to .356 (weighted average .354) in 2020, .244 to .247 (weighted average .245) in 2019 and .249 to .256 (weighted average .250) in 2018, based on the monthly per-share closing prices for three years preceding the date of

issuance. In addition, the fair value of these options was estimated based on an expected life of three to five years. The fair value of restricted stock is based on the closing per-share price of the Company’s common stock on the date of grant.
