| Summary of Significant Accounting Policies     | Summary of Significant Accounting PoliciesA detailed description of our significant accounting policies can be found in the audited financial statements for the fiscal year ended March 31, 2013, included in our Annual Report on Form 10-K. Except as described below, there have been no material changes to our significant accounting policies and estimates from those disclosed therein.Changes to Prior Period Presentation.  In the first quarter of fiscal 2014, as a result of increased visibility into our services organization, certain costs previously classified in product development expenses, were recorded in cost of goods sold to more properly reflect the nature of these expenses. The portion of these expenses that was erroneously recorded in previous periods was immaterial to the overall financial statements.  Prior period presentation has been modified to conform to the current presentation.Adopted and Recently Issued Accounting Pronouncements.In July 2012, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2012-02, Intangibles-Goodwill and Other-Testing Indefinite-Lived Intangible Assets for Impairment, to allow entities to use a qualitative approach to test indefinite-lived intangible assets for impairment. ASU 2012-02 permits an entity to first perform a qualitative assessment to determine whether it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying value. If it is concluded that this is the case, it is then necessary to perform the currently prescribed quantitative impairment test by comparing the fair value of the indefinite-lived intangible asset with its carrying value.  Otherwise, the quantitative impairment test is not required. This guidance is effective for fiscal years beginning after September 15, 2012 and early adoption is permitted.  We adopted this guidance as of April 1, 2013, and it did not have a material impact on our consolidated financial statements or related disclosures.  In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income, which amends certain provisions in ASC 220 Comprehensive Income. These provisions require the disclosure of significant amounts that are reclassified out of other comprehensive income into net income in its entirety during the reporting period. These provisions are effective for fiscal and interim periods beginning after December 15, 2012. We adopted this guidance as of April 1, 2013, and it did not have a material impact on our consolidated financial statements or related disclosures.In March 2013,  FASB issued ASU No. 2013-05, Foreign Currency Matters: Parent's Accounting for the Cumulative Translation Adjustment  upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign  Entity or of an Investment in a Foreign Entity, an amendment which allows an entity to release cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business within a foreign entity.  This is effective for fiscal years and interim reporting periods beginning after December 15, 2013, with early adoption permitted.  We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements or related disclosures.Management continually evaluates the potential impact, if any, of all recent accounting pronouncements on our consolidated financial statements or related disclosures and, if significant, makes the appropriate disclosures required by such new accounting pronouncements. |
