Item 4.02 Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

(a) On January 2, 2005, on management’s recommendation, the Board of Directors of Brocade Communication Systems, Inc. (the “Company”), in consultation with KPMG LLP, the Company’s independent auditors, and the Company’s advisors, concluded that the Company’s financial statements for the fiscal years ending 2001, 2002 and 2003, and the interim periods contained therein, should no longer be relied upon because of an error in such financial statements as addressed in Accounting Principles Board Opinion No. 20. The Company currently intends to restate its financial statements for fiscal years 2002 and 2003 and to make related adjustments to the Company’s financial statements for fiscal years prior to 2002 as necessary in connection with the filing of its Form 10-K for the fiscal year ended October 30, 2004.

     On January 6, 2005, the Company issued a press release relating to these matters, a copy of which is attached as Exhibit 99.1 hereto and incorporated herein by reference.
