In addition, the Company has standard indemnification clauses contained within its various customer contracts. As such, the Company indemnifies the parties to whom it sells its products with respect to the Company's product, alone or potentially in combination with others, infringing upon any patents, trademarks, copyrights, or trade secrets, as well as against bodily injury or damage to real or tangible personal property caused by a defective Company product. As of January 28, 2012, there have been no known material events or circumstances that have resulted in a customer contract-related indemnification liability to the Company.

Manufacturing and Purchase Commitments

Brocade has manufacturing arrangements with CMs under which Brocade provides twelve-month product forecasts and places purchase orders in advance of the scheduled delivery of products to Brocade's customers. The required lead time for placing orders with the CMs depends on the specific product. Brocade issues purchase orders and the CMs then generate invoices based on prices and payment terms mutually agreed upon and set forth in those purchase orders. Although the purchase orders Brocade places with its CMs are cancellable, the terms of the agreements require Brocade to purchase all inventory components not returnable, usable by, or sold to other customers of the CMs.

As of January 28, 2012, the Company's aggregate commitment to the CMs for inventory components used in the manufacture of Brocade products was $237.5 million, which the Company expects to utilize during future normal ongoing operations, net of a purchase commitments reserve of $5.4 million. The Company's purchase commitments reserve reflects the Company's estimate of purchase commitments it does not expect to consume in normal ongoing operations within the next twelve months.

Income Taxes

The Company has several ongoing income tax audits. For additional discussions, see Note 11, "Income Taxes," of the Notes to Condensed Consolidated Financial Statements. The Company believes it has adequate reserves for all open tax years.

Legal Proceedings

Initial Public Offering Litigation

On July 20, 2001, the first of a number of putative class actions for violations of the federal securities laws was filed in the United States District Court for the Southern District of New York against Brocade, certain of its officers and directors, and certain of the underwriters for Brocade's initial public offering ("IPO") of securities. A consolidated amended class action captioned, In re Brocade Communications Systems, Inc. Initial Public Offering Securities Litigation, No. 01 Civ. 6613, was filed on April 19, 2002. The complaint generally alleged that various underwriters engaged in improper and undisclosed activities related to the allocation of shares in Brocade's initial public offering and seeks unspecified damages for claims under the Exchange Act on behalf of a purported class of purchasers of common stock from May 24, 1999 to December 6, 2000. The lawsuit against Brocade was coordinated for pretrial proceedings with a number of other pending litigations challenging underwriter practices in over 300 cases as In re Initial Public Offering Securities Litigation, 21 MC 92 (SAS), including actions against McDATA Corporation ("McDATA"), Inrange Technologies Corporation ("Inrange") (which was first acquired by Computer Network Technology Corporation ("CNT") and subsequently acquired by McDATA as part of the CNT acquisition), and Foundry Networks LLC (formerly Foundry Networks, Inc.) ("Foundry," and collectively, the "Brocade Entities"), and certain of each entity's respective officers and directors, and initial public offering underwriters.

These actions have been resolved by a global settlement of the coordinated litigation in January 2012, under which the insurers pay the full amount of settlement share allocated to the Brocade Entities, and the Brocade Entities bear no financial liability.

Intellectual Property Litigation

On June 21, 2005, Enterasys Networks, Inc. ("Enterasys") filed a lawsuit against Foundry (and Extreme Networks, Inc.) in the United States District Court for the District of Massachusetts alleging that certain of Foundry's products infringe six of Enterasys' patents and seeking injunctive relief, as well as unspecified damages. Enterasys subsequently added Brocade as a defendant. On August 28, 2007, the Court granted Foundry's motion to stay the case based on petitions that Foundry had filed with the United States Patent and Trademark Office ("USPTO") in 2007 for reexamination of five of the six Enterasys patents. Two of the patents received final rejections during their respective reexaminations, in which the USPTO held that the claims were invalid. Enterasys filed appeals of those rejections with the USPTO's Board of Patent Appeals and Interferences in 2009. The Board partially affirmed and partially reversed one of those rejections on January 24, 2011, and Enterasys did not appeal further, which ended the proceedings on those two patents. The USPTO has issued reexamination certificates for the remaining three patents undergoing reexamination indicating that the patents were valid over the submitted references. Meanwhile, on May 21, 2010, the Court lifted the stay of the litigation, and Enterasys subsequently dropped from the litigation the two patents it appealed at the USPTO. Accordingly, four patents remain at issue in the litigation. No trial date has been set.

On September 6, 2006, Chrimar Systems, Inc. ("Chrimar") filed a lawsuit against Foundry (and D-Link Corporation and PowerDsine, Ltd.) in the United States District Court for the Eastern District of Michigan alleging that certain of Foundry's products infringe Chrimar's U.S. Patent 5,406,260 and seeking injunctive relief, as well as unspecified damages. Discovery has been completed. No trial date has been set.

On August 4, 2010, Brocade and Foundry ("Plaintiffs") filed a lawsuit against A10 Networks, Inc. ("A10"), A10's founder and other individuals in the United States District Court for the Northern District of California. On October 29, 2010, Plaintiffs filed an amended complaint. In the amended complaint, Brocade alleged that A10 and the individual defendants have misappropriated Plaintiff's trade secrets, infringed copyrighted works, interfered with existing contracts between the Plaintiffs and their employees, breached contracts, breached their fiduciary duties and duties of loyalty, and that certain of A10's products infringe 13 of Brocade's patents. Brocade is seeking injunctive relief, as well as monetary damages. On May 16, 2011, A10 filed an answer and counterclaim alleging that certain of Brocade's products infringe a patent recently acquired by A10 and seeking injunctive relief, as well as unspecified damages. On January 6, 2012 the Court granted Brocade's summary judgment motion of non-infringement of the A10 patent. Trial is scheduled for July 16, 2012.

On September 9, 2011, A10 filed a lawsuit against Brocade in the United States District Court for the Northern District of California. A10 alleges that certain of Brocade's products infringe two additional patents acquired by A10. After Brocade moved to dismiss the complaint, A10 dismissed one of its patents-in-suit. Brocade has filed a new motion to dismiss the sole remaining A10 patent. Trial is scheduled for May 2013.

General

From time to time, the Company is subject to other legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of trademarks, copyrights, patents and/or other intellectual property rights and commercial contract disputes. Third parties assert patent infringement claims against the Company from time to time in the form of letters, lawsuits and other forms of communication. In addition, from time to time, the Company receives notification from customers claiming that they are entitled to indemnification or other obligations from the Company related to infringement claims made against them by third parties. Litigation, even if the Company is ultimately successful, can be costly and divert management's attention away from the day-to-day operations of the Company.

On a quarterly basis, the Company reviews relevant information with respect to litigation contingencies and updates its accruals, disclosures and, when possible, estimates of reasonably possible losses or ranges of loss based on such reviews. However, litigation is inherently unpredictable, and outcomes are typically uncertain, and the Company's past experience does not provide any additional visibility or predictability to estimate the range of loss that may occur because the costs, outcome and status of these types of claims and proceedings have varied significantly in the past. The Company is not currently able to reasonably estimate the possible loss or range of loss from the above legal proceedings and, accordingly, the Company is unable to estimate the effects of the above on its financial condition, results of operations or cash flows.

The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated.
