| Income Tax Disclosure [Abstract] | |
| Taxes | Income Taxes For interim periods, accounting standards require that income tax expense be determined by applying the estimated annual effective income tax rate to year-to-date results, unless this method does not result in a reliable estimate of year-to-date income tax expense. Each period, the income tax accrual is adjusted to the latest estimate and the difference from the previously accrued year-to-date balance is adjusted to the current quarter. For the six months ended June 30, 2025, we recognized an income tax provision of $0.1 million on loss from continuing operations and a benefit of $14.1 million on loss from continuing operations in the same period in 2024. Our effective tax rate for the six months ended June 30, 2025 varied from the U.S. federal statutory tax rate of 21.0% primarily due to the effects of state taxes, nondeductible compensation, and a change in the state valuation allowance.

| Earnings Per Share [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Earnings per Common Share | Earnings (Loss) per Share Basic income (loss) per share is based on the weighted-average number of shares of common stock outstanding. Diluted income (loss) per share is based upon the weighted-average number of shares of common stock outstanding plus all potentially dilutive securities that were assumed to be converted into common shares at the beginning of the period under the treasury stock method. This method requires the effect of potentially dilutive common stock equivalents be excluded from the calculation of diluted earnings per share for the periods in which net losses from continuing operations are reported because the effect is anti-dilutive.
Shares excluded from the computation of diluted earnings (loss) per share were 0.3 million and 0.4 million for the quarter and six months ended June 30, 2025 and 0.4 million for the quarter and six months ended June 30, 2024 as they were either antidilutive (not in-the-money) or the required performance conditions were not met.
