Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes: As of March 31, 2013, we had approximately $1.1 million in total gross unrecognized tax benefits. Of this amount, $0.8 million (net of federal benefit on state issues), if recognized, would be recorded through the Consolidated Statement of Operations. As of March 31, 2013, 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 2012 and 2013 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, 2013, numerous states, including New Mexico, enacted legislation effective for tax years beginning on or after January 1, 2013, including changes to rates. The impact of these changes is immaterial. On January 2, 2013, the American Taxpayer Relief Act of 2012 was enacted which retroactively reinstated and extended the Federal Research and Development Tax Credit (Federal R&D Tax Credit) from January 1, 2012 to December 31, 2013, in addition to other extenders. As a result, the Company's income tax provision for the first quarter of calendar year 2013 includes a discrete tax benefit that will reduce the annual effective income tax rate. On a full year basis, the impact to the annual effective income tax rate is not expected to be material.
