Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: As of March 31, 2016, we had approximately $0.5 million in total gross unrecognized tax benefits. Of this amount, $0.3 million (net of federal benefit on state issues), if recognized, would be recorded through the Consolidated Statement of Operations. As of March 31, 2016, we had approximately $0.1 million (net of federal tax benefits) in interest and penalties recognized in income tax expense in accordance with FASB Accounting Standards Codification ("ASC") Topic 740. We are currently under examination for our U.S. federal income taxes under the Internal Revenue Service's Compliance Assurance Program for 2016 and 2015 and are subject to examination by numerous other taxing authorities in the U.S. and in jurisdictions such as Australia, Belgium, France, Canada, and Germany. We are generally no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by taxing authorities for years prior to 2010. Since January 1, 2016, numerous states, including Delaware, have enacted legislation effective for tax years beginning on or after January 1, 2016, including changes to apportionment methodologies. The impact of these changes is immaterial.
