We cannot estimate the amount of potential future payments, if any, that we might be required to make as a result of these agreements. To date, we have not paid any claim or been required to defend any action related to our indemnification obligations, and accordingly, we have not accrued any amounts for such indemnification obligations. However, we may record charges in the future as a result of these indemnification obligations. </div>   </div>  <div style="font-family: 'Times New Roman',Times,serif; margin-left: 0in; "> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">We generally warrant our devices for one year, against defects in materials, workmanship and material non-conformance to our specifications. We accrue for known warranty issues if a loss is probable and can be reasonably estimated, and accrue for estimated but unidentified issues based on historical activity.

On July 12, 2006, one of these derivative actions was voluntarily dismissed by the plaintiff shareholder. The remaining two derivative lawsuits pending in Santa Clara Superior Court were consolidated into a single action on September 5, 2006. Plaintiffs filed a second amended consolidated complaint on December 15, 2006. On January 30, 2007, Altera and the defendants filed a motion to stay this action pending resolution of the federal derivative action (discussed below). On February 11, 2009, one of the remaining derivative plaintiffs voluntarily dismissed his derivative claims and, on March 20, 2009, the other remaining derivative plaintiff filed a third amended complaint. In June 2009, Altera and the defendants demurred to the third amended complaint. After the court issued a tentative ruling in favor of Altera, the parties agreed to stay the action in order to allow plaintiff to serve a demand on Altera’s board of directors. The plaintiff served the demand on November 4, 2009. In the first quarter of 2010, the board of directors completed its review of the demand and decided to reject the plantiff’s demand. On June 1, 2010, the plaintiff filed a fourth amended complaint, alleging that the board of director’s decision to reject plaintiff’s demand was wrongful. On July 15, 2010, Altera demurred to the fourth amended complaint. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">Plaintiff asserts claims against the individual defendants for breach of fiduciary duty, waste of corporate assets, unjust enrichment, violations of California Corporation Code section 25402, breach of fiduciary duty for insider selling and misappropriation of information, and deceit. Plaintiff’s claims concern the granting of stock options by Altera between 1994 and 2001 and the alleged filing of false and misleading financial statements between 1994 and 2006. All of these claims are asserted derivatively on behalf of Altera. Plaintiff seeks, among other relief, an indeterminate amount of damages from the individual defendants and a judgment directing Altera to reform its corporate governance practices. </div> <div align="justify" style="font-size: 10pt; margin-top: 10pt; text-indent: 4%">During the months of May, June, and July 2006, four other derivative lawsuits were filed by purported Altera shareholders, on behalf of Altera, in the United States District Court for the Northern District of California. On August 8, 2006, these actions were consolidated, and the plaintiffs filed a consolidated complaint on November 30, 2006. On September 15, 2008, the plaintiffs voluntarily agreed to dismiss the case. On September 18, 2008, the court entered an order dismissing the case. </div> </div>  <!-- Begin Block Tagged Note false false false us-types:textBlockItemType textblock Includes disclosure of commitments and contingencies.
