Notes to Financial Statements
Share-based Payment Arrangement [Text Block]	Note G — Stock-Based Compensation We maintain stock incentive plans for the benefit of certain officers, directors, and employees, including the 2013 Equity Incentive Plan (the “2013 Plan”). We recently established our 2020 Equity Incentive Plan (the "2020 Plan") which has taken the place of the 2013 Plan going forward. Any shares of common stock that remain eligible for issuance under the 2013 Plan are now eligible for issuance under the 2020 Plan. Our stock incentive plans provide for the ability to issue stock options, cash stock appreciation rights, performance stock units, phantom stock units and cash performance stock units. Our cash stock appreciation rights, phantom stock units and cash performance stock units settle solely in cash and are treated as a liability, which are adjusted each reporting period based on changes in our stock price. Compensation expense for stock-based awards is based on the fair values of the awards on the date of grant and is recognized on a straight-line basis over the vesting period of the entire award in the “Labor” line of the Condensed Consolidated Statements of Comprehensive Income (Loss). We recognized $0.3 million and $0.3 million of stock-based compensation expense during the three months ended September 30, 2020 and 2019 , respectively. We recognized $0.6 million and $0.7 million of stock-based compensation expense during the nine months ended September 30, 2020 and 2019 , respectively.
