Retirement Plans

We participate in multiple 401(k) plans, whereby we provide a matching contribution of wages deferred by employees and can also make discretionary contributions to each plan. Certain plans allow for discretionary employer contributions only. These plans cover substantially all our eligible employees. During each of the three months ended March 31, 2018 and 2017, we recognized 401(k) plan expenses of $0.4 million, which is included in administrative expenses on the accompanying Condensed Consolidated Statements of Operations and Comprehensive Income.

Share-Based Compensation

Employees – Common Stock Awards

During the three months ended March 31, 2018, our employees surrendered approximately one thousand shares of our common stock to satisfy tax withholding obligations arising in connection with the vesting of common stock awards issued under our 2014 Omnibus Incentive Plan. Share-based compensation expense associated with non-performance-based awards was $0.9 million and $0.4 million for the three months ended March 31, 2018 and 2017, respectively. We recognized excess tax benefits of $0.1 million within the income tax provision in the Condensed Consolidated Statements of Operations and Comprehensive Income for each of the three months ended March 31, 2018 and 2017.

As of March 31, 2018, there was $5.1 million of unrecognized compensation expense related to these nonvested common stock awards. This expense is subject to future adjustments for forfeitures and is expected to be recognized on a straight-line basis over the remaining weighted-average period of 1.99 years. Shares forfeited are returned as treasury shares and available for future issuances. See the table below for changes in shares and related weighted average fair market value per share.

Employees – Performance-Based Stock Awards

During the three months ended March 31, 2018, we granted under our 2014 Omnibus Incentive Plan approximately sixty-three thousand shares of our common stock to certain officers, which vest in two equal installments on each of April 20, 2019 and April 20, 2020. These shares were issued in connection with the performance-based targets established in 2017. Share-based compensation expense associated with these performance-based awards was $0.4 million and $0.1 million for the three months ended March 31, 2018 and 2017, respectively. In addition, during the three months ended March 31, 2018, we established, and our Board of Directors approved, performance-based targets in connection with common stock awards to be issued to certain officers in 2019 contingent upon achievement of these 2018 targets.

Employees – Performance-Based Restricted Stock Units

During 2017, we established, and our Board of Directors approved, performance-based restricted stock units in connection with common stock awards to be issued to certain employees in 2018 contingent upon achievement of a performance target. These units will be accounted for as equity-based awards that will be settled with a fixed number of common shares. We recorded $0.9 million in compensation expense associated with these performance-based units during the three months ended March 31, 2018.

As of March 31, 2018, there was $0.2 million of unrecognized compensation expense related to nonvested performance-based common stock units. This expense is subject to future adjustments for forfeitures and is expected to be recognized on a straight-line basis over the remaining weighted-average period of .05 years. See the table below for changes in shares and related weighted average fair market value per share.
