Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: As of September 30, 2012, we had approximately $6.0 million in total gross unrecognized tax benefits. Of this amount, $5.9 million (net of federal benefit on state issues), if recognized, would be recorded through the Consolidated Statement of Operations. As of September 30, 2012, we recognized $0.1 million (net of federal tax benefits) in interest and penalties 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 for 2011 and 2012 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 before 2007. Since January 1, 2012, numerous states, including Pennsylvania, Idaho and West Virginia, enacted legislation effective for tax years beginning on or after January 1, 2012, including changes to rates and apportionment methods. We believe any adjustments related to these changes will be immaterial.
