Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense from continuing operations for the three and six months ended June 30, 2021 was $8.6 million and $12.8 million, respectively. Income tax benefit related to continuing operations for the three and six months ended June 30, 2020 was $2.3 million and $3.0 million, respectively. The change in the income tax expense for the three and six months ended June 30, 2021 compared with the income tax benefit for the three and six months ended June 30, 2020 is the result of higher pre-tax income, primarily due to an improvement in operations and acquisition and integration costs in 2020 not recurring in 2021.The reserve for uncertain tax positions at June 30, 2021 was $4.2 million, including interest and penalties.  Within the next twelve months, it is reasonably possible that $0.3 million unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
