Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense from continuing operations for the three months ended March 31, 2022 and March 31, 2021 was $1.2 million and $2.1 million, respectively. Income tax expense decreased in 2022 primarily due to change in geographic mix of income. The $1.2 million income tax expense on the $4.8 million pre-tax losses for the three months ended March 31, 2022 is due to pretax losses in various foreign jurisdictions where no tax benefit is recorded. The reserve for uncertain tax positions at March 31, 2022 was $4.9 million, including interest and penalties.  Within the next twelve months, it is reasonably possible that $0.4 million unrecognized income tax benefits will be recognized upon settlement of tax examinations and the expiration of various statutes of limitations.
