Stock-Based Compensation

Stock-Based Compensation

We maintain stock incentive plans for the benefit of certain officers, directors, and employees, including the 2013 Omnibus Incentive Plan. Our stock incentive plans include 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 $0.2 million and $0.6 million of stock-based compensation expense during the three months ended March 31, 2019 and 2018, respectively.
