Share-based Payment Arrangement [Abstract] |
Employee Benefit Plans | Note 9 — Employee Benefit Plans Long-Term Incentive Plan As of September 30, 2021, there were 5.9 million shares of our common stock available for issuance under our 2005 Long-Term Incentive Plan, as amended and restated (the “2005 Incentive Plan”). During the nine-month period ended September 30, 2021, the following grants of share-based awards were made under the 2005 Incentive Plan: ​

(1) | Reflects grants of restricted stock units (“RSUs”) to our executive officers.
(2) | Reflects grants of performance share units (“PSUs”) to our executive officers. These PSUs consist of two components: (i) 50% based on the performance of our common stock and (ii) 50% based on cumulative total Free Cash Flow. The grant date fair value represents the average grant date fair value of the two components.
(3) | Reflects grants of restricted stock to certain independent members of our Board of Directors (our “Board”) who have elected to take their quarterly fees in stock in lieu of cash.
(4) | Reflects a grant of restricted stock made to a new independent member of our Board upon his joining our Board.
Compensation cost for restricted stock is the product of the grant date fair value of each share and the number of shares granted and is recognized over the applicable vesting period on a straight-line basis. Forfeitures are recognized as they occur. No restricted stock awards have been granted to our executive officers or other employees in 2021. For the three- and nine-month periods ended September 30, 2021, $0.8 million and $2.5 million, respectively, were recognized as share-based compensation related to restricted stock. For the three- and nine-month periods ended September 30, 2020, $1.1 million and $3.2 million, respectively, were recognized as share-based compensation related to restricted stock. Our existing PSUs that were granted prior to 2021 are to be settled solely in shares of our common stock and are accounted for as equity awards. Those PSUs contain a service condition and a market condition. PSUs granted in 2021 may be settled in either cash or shares of our common stock upon vesting at the discretion of the Compensation Committee of our Board and are initially accounted for as equity awards. The PSUs granted in 2021 consist of two components: (i) 50% based on the performance of our common stock against peer group companies, which contains a service condition and a market condition, and (ii) 50% based on cumulative total Free Cash Flow, which contains a service condition 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. Compensation cost for PSUs that have a service condition and a market condition and are accounted for as equity awards is measured based on the grant date estimated fair value and recognized over the vesting period on a straight-line basis. The grant date estimated fair value is determined using a Monte Carlo simulation model. Compensation cost for PSUs that have a service condition and a performance condition and are accounted for as equity awards is initially measured based on the grant date fair value. Cumulative compensation cost is subsequently adjusted at the end of each reporting period to reflect the current estimation of achieving the performance condition. For the three- and nine-month periods ended September 30, 2021, $1.0 million and $3.1 million, respectively, were recognized as share-based compensation related to equity PSUs. For the three- and nine-month periods ended September 30, 2020, $1.0 million and $3.0 million, respectively, were recognized as share-based compensation related to equity PSUs. In January 2021, based on the performance of our common stock price as compared to our performance peer group over a three-year period, 368,038 equity PSUs granted in 2018 vested at 200%, representing 736,075 shares of our common stock with a total market value of $3.1 million. RSUs granted in 2021 have been accounted for as liability awards. Liability RSUs are measured at their estimated fair value at each balance sheet date, and subsequent changes in the fair value of the awards are recognized in earnings for the portion of the award for which the requisite service period has elapsed. Cumulative compensation cost for vested liability RSUs equals the actual payout value upon vesting. Compensation cost recognized for the three-month period ended September 30, 2021 was minimal. For the nine-month period ended September 30, 2021, $0.4 million was recognized as compensation cost. In 2021 and 2020, we granted fixed-value cash awards of $3.5 million and $4.7 million, respectively, to select management employees under the 2005 Incentive Plan. The value of these cash awards is recognized on a straight-line basis over a vesting period of three years. For the three- and nine-month periods ended September 30, 2021, $1.0 million and $3.0 million, respectively, were recognized as compensation cost. For the three- and nine-month periods ended September 30, 2020, $1.1 million and $3.4 million, respectively, were recognized as compensation cost. Defined Contribution Plan We sponsor a defined contribution 401(k) retirement plan. We suspended our discretionary contributions for an indefinite period beginning January 2021. Employee Stock Purchase Plan We have an employee stock purchase plan (the “ESPP”). As of September 30, 2021, 1.6 million shares were available for issuance under the ESPP. The ESPP currently has a purchase limit of 260 shares per employee per purchase period. For more information regarding our employee benefit plans, including the 2005 Incentive Plan and the ESPP, see Note 14 to our 2020 Form 10-K.
