Stock-Based Compensation

STOCK-BASED COMPENSATION

The Company’s Board of Directors has adopted various stock-based compensation plans. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and performance stock units. Pursuant to the plans, shares are reserved for future issuance by the Company upon exercise of stock options or awards of restricted stock, restricted stock units, or performance stock units granted to directors, officers and other key employees.

The table below summarizes the transactions under the Company’s active stock-based compensation plans for the three months ended March 31, 2022:

Stock-based compensation expense was $3.9 million during both three month periods ended March 31, 2022 and 2021. Stock-based compensation expense is recognized ratably over the requisite service period for all stock-based awards. There was no unrecognized stock-based compensation expense related to stock options at March 31, 2022. Unrecognized stock-based compensation expense related to non-vested stock awards and stock units was $18.2 million at March 31, 2022. At such date, the weighted-average period over which this unrecognized expense is expected to be recognized was 1.9 years.

The intrinsic value of stock options outstanding and stock options exercisable at March 31, 2022 was $1.8 million. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $26.22 as of March 31, 2022, and the exercise price multiplied by the number of options outstanding. There was no intrinsic value of stock options exercised during the three months ended March 31, 2022, while the total intrinsic value of stock options exercised during the three months ended March 31, 2021, was $1.2 million.

The fair value of the Company’s employee stock options granted is estimated on the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. There were no stock options granted during the three months ended March 31, 2022 and 2021.
