Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	Summary of Significant Accounting Policies There have been no material changes in the Company’s significant accounting policies for the nine months ended August 1, 2015, as compared to the significant accounting policies disclosed in Brocade’s Annual Report on Form 10-K for the fiscal year ended November 1, 2014. New Accounting Pronouncements or Updates Recently Adopted In March 2013, the Financial Accounting Standards Board (“FASB”) issued an update to Accounting Standards Codification (“ASC”) 830, 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. Under this update, an entity is required to release any cumulative translation adjustment into net income when the entity ceases to have a controlling financial interest resulting from the complete, or substantially complete, liquidation of a subsidiary or group of assets within a foreign entity. This update should be applied prospectively. The Company adopted this update in the first quarter of fiscal year 2015. There was no material impact on the Company’s financial position, results of operations, or cash flows. In June 2015, the FASB issued an update to the Accounting Standards Codification (the “Codification”), Technical Corrections and Improvements. This update includes various amendments to clarify the Codification, correct unintended application of guidance, or make minor improvements to the Codification. This update is not intended to change U.S. GAAP. The Company adopted this update in the third quarter of fiscal year 2015. There was no material impact on the Company’s financial position, results of operations, or cash flows. Recent Accounting Pronouncements or Updates That Are Not Yet Effective In April 2014, the FASB issued an update to ASC 205, Presentation of Financial Statements, and ASC 360, Property, Plant, and Equipment: Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. Under this update, a discontinued operation may include a component of an entity or a group of components of an entity, or a business or nonprofit activity. Only those disposals of components of an entity that represent a strategic shift that has, or will have, a major effect on an entity’s operations and financial results will be reported as discontinued operations in the financial statements. This update should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2016. Early adoption is permitted, but only for disposals that have not been reported in financial statements previously issued. The Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. In May 2014, the FASB issued an update to ASC 606, Revenue from Contracts with Customers, that will supersede virtually all existing revenue guidance. Under this update, an entity is required to recognize revenue upon transfer of promised goods or services to customers, in an amount that reflects the expected consideration received in exchange for those goods or services. As such, an entity will need to use more judgment and make more estimates than under the current guidance. This update should be applied retrospectively, either to each prior reporting period presented in the financial statements, or only to the most current reporting period presented in the financial statements with a cumulative effect adjustment recorded in the retained earnings. In August 2015, the FASB issued an update to defer the effective date of this update by one year. This update becomes effective and will be adopted by the Company in the first quarter of fiscal year 2019. Early adoption is not permitted for reporting periods before the first quarter of fiscal year 2018. The Company is currently evaluating the impact of this update on its consolidated financial statements. In April 2015, the FASB issued an update to ASC 835, Interest—Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs. Under this update, debt issuance costs related to a debt liability are required to be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs are not affected by this update. This update is effective for the Company in the first quarter of fiscal year 2017, with early adoption permitted. This update should be applied retrospectively to all prior periods presented in the financial statements and will be early adopted by the Company in the first quarter of fiscal year 2016. The Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. In April 2015, the FASB issued an update to ASC 350, Intangibles—Goodwill and Other—Internal-Use Software: Customer’s Accounting for Fees Paid in Cloud Computing Arrangement. This update provides guidance on the accounting for fees paid in a cloud computing arrangement if the arrangement was determined to include a software license. This update will not change U.S. GAAP for a customer’s accounting for service contracts. This update may be applied either prospectively or retrospectively and will be adopted by the Company in the first quarter of fiscal year 2017. Early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. In July 2015, the FASB issued an update to ASC 330, Inventory: Simplifying the Measurement of Inventory. Under this update, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated cost of completion and disposal. This update does not apply to inventory that is measured using last-in, first-out or the retail inventory method. This update should be applied prospectively and will be adopted by the Company in the first quarter of fiscal year 2018. Early adoption is permitted. The Company is currently evaluating the impact of this update on its consolidated financial statements. Concentrations Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, and accounts receivable. Cash and cash equivalents are primarily maintained at five major financial institutions. Deposits held with banks may be redeemed upon demand and may exceed the amount of insurance provided on such deposits. A majority of the Company’s accounts receivable balance is derived from sales to original equipment manufacturer (“OEM”) partners in the computer storage and server industry. As of August 1, 2015, two customers individually accounted for 13% and 12% of total accounts receivable, for a combined total of 25% of total accounts receivable, and no other customers individually accounted for more than 10% of total accounts receivable. As of November 1, 2014, three customers individually accounted for 15%, 12%, and 11% of total accounts receivable, for a combined total of 38% of total accounts receivable. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable balances. The Company has established reserves for credit losses, sales allowances, and other allowances. For the three months ended August 1, 2015, three customers individually accounted for 16%, 15%, and 12% of the Company’s total net revenues for a combined total of 43% of total net revenues. For the three months ended August 2, 2014, three customers individually accounted for 21%, 16%, and 11% of the Company’s total net revenues for a combined total of 48% of total net revenues. The Company currently relies on single and limited sources for multiple key components used in the manufacture of its products. Additionally, the Company relies on multiple contract manufacturers (“CMs”) for the production of its products. Although the Company uses standard parts and components for its products where possible, the Company’s CMs currently purchase, on the Company’s behalf, several key components used in the manufacture of products from single or limited supplier sources.
