STOCK-BASED COMPENSATION | 12. STOCK-BASED COMPENSATION The Company’s 2006 Long-Term Stock Incentive Plan, 2012 Long-Term Stock Incentive Plan and 2021 Long-Term Stock Incentive Plan allow the granting of shares of the Company’s common stock as incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units and stock appreciation rights to directors, officers and employees of the Company and its subsidiaries. As of December 31, 2021, the total number of shares available for grant in all active plans was 1,730,542. There are no shares remaining for issuance with respect to the stock option plan approved in 2002; however, options granted under this plan are still included in the numbers below. Options granted under the stock incentive plans are, in general, exercisable not earlier than one year after the date of grant, at a price equal to the fair value of the common stock on the date of grant and expire not more than ten years after the date of grant. Stock options may vest during a period of up to five years after the date of grant. The Company has a policy of using authorized but unissued shares to satisfy option exercises. Upon adoption of Accounting Standards Update (“ASU”) 2016-09, “Compensation - Stock Compensation (Topic 718), Improvements to Employee Share-Based Payment Accounting,” the Company has elected to account for forfeitures as they occur, rather than estimate expected forfeitures. Changes in options outstanding during 2021 were as follows:

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between the Company’s closing stock price on the last trading day of 2021 and the exercise price, multiplied by the number of in-the-money options). The Company’s closing stock price on December 31, 2021 was $35.40. There were no stock options granted in 2021. As of December 31, 2021, there was no unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Company’s stock incentive plans.

There were 215,716 service-based restricted stock units granted during 2021. The performance-based awards are dependent upon the Company meeting certain performance criteria and, to the extent the performance criteria are met, will cliff vest at the end of the performance period, which is generally three years. There were 51,710 performance-based restricted units granted during 2021. As of December 31, 2021, there was $12.5 million of total unrecognized compensation cost related to both service and performance-based units. That cost is expected to be recognized over a weighted average period of 1.46 years. Total stock-based compensation expense recognized for stock awards/units totaled $7.1 million, $6.9 million and $5.9 million in 2021, 2020 and 2019, respectively.
