Share-based Payment Arrangement [Abstract] |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION The Company has stock incentive plans for executives and eligible employees. Stock awards include restricted stock, performance shares and stock options. Stock-based compensation expense for the years ended December 31, 2020, 2019, and 2018 was $8.5 million, $9.3 million and $8.3 million, respectively. At December 31, 2020, there was $8.7 million of unrecognized stock-based compensation cost which is expected to be recognized over a weighted-average remaining vesting period of 1.6 years. Restricted Stock Restricted stock granted under the Company’s incentive plans are accounted for based on the market value of the underlying shares on the date of grant and generally vest in equal installments annually over three years. Restricted stock awards are accounted for as equity awards. Holders of restricted stock are entitled to vote the shares and to receive any dividends declared on the shares. The following table summarizes restricted stock activity for the years ended December 31, 2020, 2019, and 2018:
| Restricted Stock |  |
| Number of Shares |  | Weighted Average Grant Date Fair Value |  |  |  |
Outstanding at December 31, 2017 | 2,155,845 |  |  | $ | 5.72 |  |  |  |  |
Granted | 1,000,690 |  |  | 7.63 |  |  |  |  |

Canceled/Forfeited | (337,811) |  |  | 6.51 |  |  |  |  |
Outstanding at December 31, 2018 | 1,541,648 |  |  | $ | 7.14 |  |  |  |  |

At December 31, 2020, there was $4.4 million of unrecognized compensation cost related to restricted stock awards to be recognized over a weighted-average period of 1.4 years. Performance Shares Performance shares granted under the Company’s incentive plans are accounted for as equity awards at fair value using a Monte Carlo simulation valuation model. Performance shares granted during and subsequent to 2018 will vest at the end of a three-year service period if internal performance metrics are met, with the number of shares vesting impacted by the inclusion of a modifier based upon a relative stockholder return metric. The relative stockholder return metric is included in the determination of the grant date fair value of the performance shares; however, the recognition of compensation cost for performance share awards is based on the results of the internal performance metrics. Outstanding performance shares granted prior to 2018 will vest at the end of a three-year service period if relative stockholder return and internal performance metrics are met. The existence of a market condition requires recognition of compensation cost for the performance share awards over the requisite period regardless of whether the relative stockholder return metric is met. The following table summarizes performance shares activity for the years ended December 31, 2020, 2019, and 2018:
| Performance Shares |  |
| Number of Shares |  | Weighted Average Grant Date Fair Value |  |  |  |

(2) Includes 207,264 additional shares granted and 300,267 shares cancelled in connection with the vesting of the 2016 award in 2019 due to above-target and below target performance, respectively, in accordance with the terms of the award. (3) Includes 6,226 additional shares granted and 143,808 shares cancelled in connection with the vesting of the 2017 award in 2020 due to above-target and below target performance, respectively, in accordance with the terms of the award. At December 31, 2020, there was $4.3 million of unrecognized compensation cost related to performance shares to be recognized over a weighted average period of 1.9 years. Stock Options and Stock Appreciation Rights Stock options and stock appreciation rights (SARs) granted under the Company’s incentive plans generally vest over three years and are exercisable over a period not to exceed ten years from the grant date. The exercise price of stock options is equal to the fair market value of the shares on the date of the grant. The value of each stock option award is estimated using the Black-Scholes option pricing model. Stock options are accounted for as equity awards and SARs are accounted for as liability awards and remeasured at each reporting date. SARs, when vested, provide the participant the right to receive cash equal to the excess of the market price of the shares over the exercise price when exercised. The following table sets forth the weighted average fair value of stock options and the assumptions used to estimate the fair value of the stock options using the Black-Scholes option valuation model:
