Stock-Based Compensation | 13. Stock-Based Compensation The Company’s 2013 Omnibus Incentive Plan (the “2013 Plan”) was approved by shareholders on May 7, 2013 and replaced several of the Company's incentive plans (collectively referred to as the “Prior Plans”). No new awards may be granted under the Prior Plans; however, outstanding awards under the Prior Plans will continue in force and effect pursuant to their terms. The 2013 Plan provides for both short-term and long-term incentive awards for employees and non-employee directors. Stock-based awards may take the form of stock options, stock appreciation rights, restricted stock (“RSAs”), restricted stock units (“RSUs”) and performance shares or performance unit awards. The total number of shares of the Company’s common stock available for awards under the 2013 Plan is 7,477,395 shares. Stock-based compensation expense was $3.1 million and $2.4 million for the three months ended March 31, 2019 and 2018, respectively. The Company recognizes stock-based compensation expense over the awards' vesting period. Options to acquire 210,243 and 160,462 shares of common stock were granted to employees during the three months ended March 31, 2019 and 2018, respectively. The options granted in 2019 and 2018 become exercisable in three annual increments over a three-year period beginning on the first anniversary of the grant date and expire 10 years subsequent to the grant date. A total of 176,371 and 31,220 RSUs were issued by the Company to employees during the three months ended March 31, 2019 and 2018, respectively. The RSUs granted to employees vest on the third anniversary of the grant date. A total of 228,037 and 76,531 performance shares were issued during the three months ended March 31, 2019 and 2018, respectively. Performance shares are earned based on the extent to which performance goals are met over the applicable performance period. The performance goals and the applicable performance period vary for each grant year. The performance goals for the performance shares granted in 2019 and 2018 are based 50% on total shareholder return relative to peers during the three-year performance period and 50% on Adjusted EBITDA percentage from continuing operations in 2021 and 2020, respectively. Depending on the foregoing factors, the number of shares earned could range from zero to two times the amount of performance shares outstanding. The Company issued a total of 50,673 and 22,936 equity grants to directors during the three months ended March 31, 2019 and 2018, respectively. The 2019 and 2018 equity grants vested immediately upon the grant date.
