Income Tax Disclosure [Abstract]  
Income Taxes Income Taxes Income tax expense from continuing operations for the three months ended March 31, 2021 was $4.2 million compared with an income tax benefit from continuing operations of $0.7 million for the three months ended March 31, 2020. The change in the income tax expense for the three months ended March 31, 2021 compared with the income tax benefit for the three months ended March 31, 2020 is the result of higher taxable income, primarily due to an improvement in operations and acquisition and integration costs in 2020 not recurring in 2021, partially offset by debt refinancing expenses in 2021.An income tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, based on technical merits, including resolutions of any related appeals or litigation processes. The reserve for uncertain tax positions at March 31, 2021 was $4.3 million, including interest and penalties.  Within the next twelve months, it is reasonably possible that $0.6 million unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
