Commitments And Contingencies	Note 10 — Commitments and Contingencies *Indemnities, Commitments, Contingencies and Guarantees* In the normal course of our business, we make certain indemnities, commitments and guarantees under which we may be required to make payments in relation to certain transactions. These indemnities, commitments and guarantees include, among others, intellectual property indemnities to our customers in connection with the sale of our products and licensing of our technology, indemnities for liabilities associated with the infringement of other parties' technology based upon our products and technology, guarantees of timely performance of our obligations, guarantees and indemnities related to the reliability and performance of our equipment, and indemnities to our directors and officers to the maximum extent permitted by law. The duration of these indemnities, commitments and guarantees varies, and, in certain cases, is indefinite. Many of these indemnities, commitments and guarantees do not provide for any limitation of the maximum potential future payments that we could be obligated to make. We have not recorded a liability for these indemnities, commitments or guarantees in the accompanying balance sheets because future payment is not probable. From time to time, various claims and litigation are asserted or commenced against us arising from or related to contractual matters, intellectual property matters, product warranties and personnel and employment disputes. As to such claims and litigation, including those described below, we can give no assurance that we will prevail. On January 6, 2011, a purported class action complaint was filed against us and certain of our current and former officers in the U.S. District Court for the Eastern District of North Carolina alleging claims under Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended, and Rule 10b-5 promulgated thereunder. On June 30, 2011, an amended complaint was filed alleging the same causes of action. The case purports to be brought on behalf of a class of purchasers of our stock during the period February 11, 2010 to August 5, 2010. The amended complaint generally alleges violations of federal securities laws based on, among other things, claimed misstatements or omissions regarding our business and prospects in India and for certain signaling products. The amended complaint seeks unspecified damages, interest, attorneys' fees, costs, and expenses. As we are in the very early stages of this potential litigation, we are unable to predict the outcome of this case or estimate a range of potential loss related to this matter. Although the Company denies the allegations in the amended complaint and intends to vigorously pursue its defense, we are unable to predict the outcome of this case. An adverse court determination in the purported class action lawsuit against us could result in significant liability and could have a material adverse effect on our business, results of operations and financial condition. On February 7, 2011, a shareholder derivative complaint was filed in the California Superior Court of Santa Clara County against certain current and former officers and directors. The suit alleges that named parties breached their fiduciary duties to the Company by, among other things, making statements between February, 2010 and August, 2010 which plaintiffs claim were false and misleading and by allegedly failing to implement adequate internal controls and means of supervision at the Company. On March 3, 2011, a nearly identical shareholder derivative complaint was filed in the U.S. District Court for the Central District of California. These suits seek an unspecified amount of damages from the named parties and modifications to the Company's corporate governance policies. The allegations in the complaints are similar to the purported class action complaint discussed above. The individual defendants intend to vigorously defend the suits and the Company, on whose behalf these claims purport to be brought, intends to move to dismiss the shareholder derivative complaints on the grounds that the derivative plaintiffs did not file the claims in accordance with applicable laws governing the filing of derivative suits. As we are in the very early stages of these litigations, we are unable to predict the outcome of these cases or estimate a range of potential costs related to these matters.
