We are required to adopt this standard in the third quarter of 2012.

The new standard requires the presentation of comprehensive income, the components of net income and the components of other comprehensive income either in a single continuous statement of comprehensive income or in two separate but consecutive statements. We are required to adopt this standard as of the beginning of 2013. The new standard also required presentation of adjustments for items that are reclassified from other comprehensive income to net income in the statement where the components of net income and the components of other comprehensive income are presented, which was indefinitely deferred by an update issued by the FASB in December 2011. The adoption of these standards will only impact the presentation of our financial statements.</font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div></div>

("Rambus") relating to certain of Rambus' patents and certain of our claims and defenses. Our lawsuits with Rambus are pending in the U.S. District Court for the District of Delaware, U.S. District Court for the Northern District of California, Germany, France, and Italy. On August 28, 2000, we filed a complaint against Rambus in the U.S. District Court for the District of Delaware seeking declaratory and injunctive relief. The complaint alleges, among other things, various anticompetitive activities and also seeks a declaratory judgment that certain Rambus patents are invalid and/or unenforceable. Rambus subsequently filed an answer and counterclaim in Delaware alleging, among other things, infringement of twelve Rambus patents and seeking monetary damages and injunctive relief. We subsequently added claims and defenses based on Rambus' alleged spoliation of evidence and litigation misconduct. The spoliation and litigation misconduct claims and defenses were heard in a bench trial before Judge Robinson in October 2007. On January 9, 2009, Judge Robinson entered an opinion in our favor holding that Rambus had engaged in spoliation and that the twelve Rambus patents in the suit were unenforceable against us. Rambus subsequently appealed the decision to the U.S. Court of Appeals for the Federal Circuit. On May 13, 2011, the Federal Circuit affirmed Judge Robinson's finding of spoliation, but vacated the dismissal sanction and remanded the case to the Delaware District Court for analysis of the remedy based on the Federal Circuit's decision. On January 13, 2006, Rambus filed a lawsuit against us in the U.S. District Court for the Northern District of California alleging that certain of our DDR2, DDR3, RLDRAM and RLDRAM II products infringe as many as fourteen Rambus patents and seeking monetary damages, treble damages, and injunctive relief. The Northern District of California Court stayed the trial of the patent phase of the Northern District of California case upon appeal of the Delaware spoliation issue to the Federal Circuit.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On March 6, 2009, Panavision Imaging, LLC filed suit against us and Aptina Imaging Corporation, then a wholly-owned subsidiary, in the U.S. District Court for the Central District of California. The complaint alleged that certain of our and Aptina's image sensor products infringed four Panavision Imaging U.S. patents and sought injunctive relief, damages, attorneys' fees, and costs. On February 7, 2011, the Court ruled that one of the four patents in suit was invalid for indefiniteness. On March 10, 2011, claims relating to the remaining three patents in suit were dismissed with prejudice. Panavision subsequently filed a motion for reconsideration of the Court's decision regarding invalidity of the first patent, and we filed a motion for summary judgment of non-infringement of such patent. On July 8, 2011, the Court issued an order that rescinded its prior indefiniteness decision, and held that the disputed term does not render the claims in suit indefinite. A hearing on motions for summary judgment regarding infringement and validity is scheduled for April 2, 2012.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On September 1, 2011, HSM Portfolio LLC and Technology Properties Limited LLC filed a patent infringement action in the U.S. District Court for the District of Delaware against us and seventeen other defendants.

Rambus is seeking a judgment for damages of approximately $3.9 billion, joint and several liability, trebling of damages awarded, punitive damages, a permanent injunction enjoining the defendants from the conduct alleged in the complaint, interest, and attorneys' fees and costs. Trial began on June 20, 2011, and the case went to the jury on September 21, 2011.

The complaints seek joint and several damages, trebled, in addition to restitution, costs and attorneys' fees. A number of these cases have been removed to federal court and transferred to the U.S. District Court for the Northern District of California for consolidated pre-trial proceedings. In July, 2006, the Attorneys General for approximately forty U.S. states and territories filed suit in the U.S. District Court for the Northern District of California. The complaints allege, among other things, violations of the Sherman Act, Cartwright Act, and certain other states' consumer protection and antitrust laws and seek joint and several damages, trebled, as well as injunctive and other relief. On October 3, 2008, the California Attorney General filed a similar lawsuit in California Superior Court, purportedly on behalf of local California government entities, alleging, among other things, violations of the Cartwright Act and state unfair competition law. On June 23, 2010, we executed a settlement agreement resolving these purported class-action indirect purchaser cases and the pending cases of the Attorneys General relating to alleged DRAM price-fixing in the United States. Subject to certain conditions, including final court approval of the class settlements, we agreed to pay approximately $67 million in aggregate in three equal installments over a two-year period. As of December 1, 2011, we paid $45 million into an escrow account in accordance with the settlement agreement.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">Three putative class action lawsuits alleging price-fixing of DRAM products also have been filed against us in Quebec, Ontario, and British Columbia, Canada, on behalf of direct and indirect purchasers, asserting violations of the Canadian Competition Act and other common law claims.  The claims were initiated between December 2004 (British Columbia) and June 2006 (Quebec). The plaintiffs seek monetary damages, restitution, costs, and attorneys' fees. The substantive allegations in these cases are similar to those asserted in the DRAM antitrust cases filed in the United States.  Plaintiffs' motion for class certification was denied in the British Columbia and Quebec cases in May and June 2008, respectively.  Plaintiffs subsequently filed an appeal of each of those decisions.  On November 12, 2009, the British Columbia Court of Appeal reversed, and on November 16, 2011, the Quebec Court of Appeal also reversed, the denial of class certification and remanded the cases for further proceedings.  </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">On June 21, 2010, the Brazil Secretariat of Economic Law of the Ministry of Justice ("SDE") announced that it had initiated an investigation relating to alleged anticompetitive activities within the DRAM industry.

("Oracle"), successor to Sun Microsystems, a DRAM purchaser that opted-out of a direct purchaser class action suit that was settled, filed suit against us in U.S. District Court for the Northern District of California. The complaint alleges a conspiracy to increase DRAM prices and other violations of federal and state antitrust and unfair competition laws based on purported conduct for the period from August 1, 1998 through at least June 15, 2002. Oracle is seeking joint and several damages, trebled, as well as restitution, disgorgement, attorneys' fees, costs and injunctive relief.</font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">We are unable to predict the outcome of these matters and therefore cannot estimate the range of possible loss, except as noted in the U.S. indirect purchasers cases above.

The complaint seeks to void under Section 133 of the German Insolvency Act a share purchase agreement between us and Qimonda in fall 2008 pursuant to which we purchased all of Qimonda's shares of Inotera Memories, Inc. and seeks an order requiring us to retransfer the Inotera shares to the Qimonda estate. The complaint also seeks to terminate under Sections 103 or 133 of the German Insolvency Code a patent cross license between us and Qimonda entered into at the same time as the share purchase agreement. A hearing scheduled to begin on November 9, 2011 was continued and has not yet been rescheduled. We are unable to predict the outcome of this lawsuit and therefore cannot estimate the range of possible loss. The final resolution of this lawsuit could result in the loss of the Inotera shares or equivalent monetary damages and the termination of the patent cross license, which could have a material adverse effect on our business, results of operation or financial condition.</font></div><div style="line-height:120%;text-align:justify;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br clear="none"/></font></div><div style="line-height:120%;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">In the normal course of business, we are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party.
