Basis of Presentation [Abstract]
Basis of Presentation	1. Basis of Presentation We have prepared our condensed consolidated financial statements included in this Form 10-Q, without audit, pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in the consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted, pursuant to such rules and regulations, although we believe that our disclosures are adequate to make the information not misleading. The consolidated results of operations for any interim period are not necessarily indicative of results for a full year. These condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the year ended March 31, 2011. The condensed consolidated financial statements presented herein as of December 31, 2011 and for the three- and nine- month periods ended December 31, 2011 and 2010 reflect, in the opinion of management, all material adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods. We have identified certain accounting policies that we consider particularly important for the portrayal of our results of operations and financial position and which may require the application of a higher level of judgment by our management, and as a result are subject to an inherent level of uncertainty. These are characterized as “critical accounting policies” and address revenue recognition, accounts receivable, inventories, foreign currency translation and transactions, impairment of long-lived assets, share-based compensation, defined benefit pension plans and income taxes, each of which is described in our Annual Report on Form 10-K for the year ended March 31, 2011. Based upon our review, we have determined that these policies remain our most critical accounting policies for the three and nine months ended December 31, 2011 and we have made no changes to these policies during fiscal 2012.

The entire disclosure for the organization, consolidation and basis of presentation of financial statements disclosure, and significant accounting policies of the reporting entity.
