Employee Benefit Plans |
Employee Benefit Plans | Note 13 — Employee Benefit Plans Long-Term Incentive Plan We currently have one active long-term incentive plan, the 2005 Long-Term Incentive Plan, as amended and restated (the “2005 Incentive Plan”). The 2005 Incentive Plan is administered by the Compensation Committee of our Board (the “Compensation Committee”). The Compensation Committee also determines the type of award to be made to each recipient and, as set forth in the related award agreement, the terms, conditions and limitations applicable to each award. The Compensation Committee may grant various forms of award in accordance with the 2005 Incentive Plan. Awards that have been granted to employees under the 2005 Incentive Plan have a vesting period of three years (or 33% per year) with the exception of PSUs, which vest in amounts in accordance with their terms on the third anniversary date of the grant. On May 15, 2024, our shareholders approved an amendment to and restatement of the 2005 Incentive Plan, which, among other things, authorizes 7.0 million additional shares for issuance pursuant to our equity incentive compensation strategy. The 2005 Incentive Plan currently has 24.3 million shares authorized for issuance, which includes a maximum of 2.0 million shares that may be granted as incentive stock options. As of December 31, 2024, there were approximately 9.4 million shares of our common stock available for issuance under the 2005 Incentive Plan and no incentive stock options are currently outstanding. The following grants of share-based awards were made in 2024 under the 2005 Incentive Plan: ​

(2) | During the years ended December 31, 2024, 2023 and 2022, total fair value of vested restricted stock was $1.5 million, $2.9 million and $2.9 million, respectively.
​ For the years ended December 31, 2024, 2023 and 2022, $1.0 million, $1.3 million and $2.5 million, respectively, were recognized as share-based compensation related to restricted stock. Future compensation cost and the weighted average vesting period associated with unvested restricted stock at December 31, 2024 were approximately $0.9 million and 0.8 years, respectively. PSU Awards Our PSUs granted beginning in January 2021 may be settled in either cash or shares of our common stock, or a combination thereof, upon vesting at the discretion of the Compensation Committee and generally have been accounted for as equity awards. Those PSUs consist of two components: (i) 50% based on the performance of our common stock against peer group companies (TSR component), which component contains a service and a market condition, and (ii) 50% based on cumulative total Free Cash Flow (FCF component), which component contains a service and a performance condition. Free Cash Flow is calculated as cash flows from operating activities less capital expenditures, net of proceeds from sale of assets. Our PSUs cliff vest at the end of a three-year period with the maximum amount of the award being 200% of the original PSU awards and the minimum amount being zero.
