Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes 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. Income tax expense related to continuing operations for the three and six months ended June 30, 2019 was $4.0 million and $5.2 million, respectively. The change in the income tax benefit for the three and six months ended June 30, 2020 compared with the income tax expense for the three months and six months ended June 30, 2019 is the result of lower taxable income, primarily resulting from decreased operating income as a result of the impacts of COVID-19 and incremental acquisition and integration costs of approximately $5 million and $16 million for the three and six months ended June 30, 2020, respectively, to support the ESOL acquisition.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 June 30, 2020 was $3.7 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.
