The 2017 Long-Term Incentive Plan (the “2017 Incentive Plan”) was approved by the Board of Directors and subsequently approved by the Company’s stockholders at the 2017 annual meeting. The 2017 Incentive Plan authorizes a broad range of awards including stock options, stock appreciation rights, restricted stock and restricted stock units, performance shares or units, other stock-based awards, and cash incentive awards to all employees (including the Company’s executive officers), directors, consultants, independent contractors or agents of us or a related company. The 2017 Incentive Plan is effective as of March 15, 2017.

As of December 31, 2021, 401,451 shares were available for future grant under the 2017 Incentive Plan.

We have awarded time-based restricted stock to our employees and the Company’s non-employee directors (“Outside Directors”). This restricted stock generally vests ratably (once per year) over a three to five-year period for recipients other than Outside Directors. Outside Directors’ restricted stock vests over a one-year period. In 2021, 2020 and 2019 we also granted performance-based restricted stock to our executive officers. The performance-based restricted stock vests upon the third anniversary of its issuance if certain financial targets are achieved.

Share-based compensation expense for 2021, 2020 and 2019 was $20.1 million, $17.1 million and $16.3 million or $14.9 million, $13.1 million and $12.1 million, net of taxes, respectively. Included in the 2021, 2020 and 2019 share-based compensation expense was $5.8 million, $4.5 million and $3.4 million of performance-based share expenses or $4.3 million, $3.5 million and $2.6 million, net of taxes, respectively.

The fair value of non-vested restricted stock is equal to the market price of our stock at the date of grant.
