Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company maintains income tax valuation allowances on its U.S. Federal and state deferred tax assets due to a three year cumulative loss condition, which limits the ability to consider other positive subjective evidence, such as projections of future results, to assess the realizability of deferred tax assets. Results in both 2018 and 2017 include impacts from income taxes that differ from applicable standard tax rates, primarily related to the income tax valuation allowance. First quarter 2018 results included a provision for income taxes of $5.0 million, or 7.6% of income before income taxes, primarily related to income taxes on non-U.S. operations. The first quarter 2017 provision for income taxes was $2.0 million, or 8.7% of income before income taxes, which included $1.3 million of discrete tax benefits. The Company continues to account for impacts of the Tax Cuts and Jobs Act (Tax Act) as estimated amounts, pending further information and analysis, which includes final tax return filings, analysis of foreign earnings and profits, and interpretive Internal Revenue Service guidance. At this time, the Company has not made any material adjustments to the provisional Tax Act impacts recorded in its 2017 financial statements, and the Company continues to expect to finalize these provisional amounts by the fourth quarter of 2018.
