Share-based Compensation	9 Months Ended
Share-based Compensation	Sep. 30, 2024
Share-Based Payment Arrangement [Abstract]
Share-based Payment Arrangement	SHARE-BASED COMPENSATION We grant various equity-based awards relating to Class B common stock to employees under our 2017 Omnibus Incentive Plan (“the Plan”). These awards have historically consisted of restricted shares, RSUs, performance-based restricted shares (“performance shares”), PSUs, and non-qualified stock options. Performance shares and PSUs granted are earned based on attainment of threshold performance of earnings and return on capital targets, in addition to a multiplier applied based on rTSR against peers over the performance period. Share-based compensation expense was $4.1 million and $4.4 million for the three months ended September 30, 2024 and 2023, respectively, and $9.2 million and $13.3 million for the nine months ended September 30, 2024 and 2023, respectively. We recognize share-based compensation expense over the awards’ vesting period. As of September 30, 2024, we had $20.2 million of pre-tax unrecognized compensation cost related to outstanding share-based compensation awards expected to be recognized over a weighted average period of 1.8 years.
