Notes to financial statements [Abstract]
3dfx	3dfx During fiscal year 2002, we completed the purchase of certain assets from 3dfx Interactive, Inc., or 3dfx, for an aggregate purchase price of $74.2 million. On December 15, 2000, NVIDIA Corporation and one of our indirect subsidiaries entered into an Asset Purchase Agreement, or the APA, which closed on April 18, 2001, to purchase certain graphics chip assets from 3dfx. In October 2002, 3dfx filed for Chapter 11 bankruptcy protection in the United States Bankruptcy Court for the Northern District of California. In March 2003, the Trustee appointed by the Bankruptcy Court to represent 3dfx’s bankruptcy estate served his complaint on NVIDIA. The Trustee’s complaint asserted claims for, among other things, successor liability and fraudulent transfer and sought additional payments from us. In early November 2005, NVIDIA and the Official Committee of Unsecured Creditors, or the Creditors’ Committee, agreed to a Plan of Liquidation of 3dfx, which included a conditional settlement of the Trustee’s claims against us. This conditional settlement was subject to a confirmation process through a vote of creditors and the review and approval of the Bankruptcy Court. The conditional settlement called for a payment by NVIDIA of $30.6 million to the 3dfx estate. Under the settlement, $5.6 million related to various administrative expenses and Trustee fees, and $25.0 million related to the satisfaction of debts and liabilities owed to the general unsecured creditors of 3dfx. Accordingly, during the three month period ended October 30, 2005, we recorded $5.6 million as a charge to settlement costs and $25.0 million as additional purchase price for 3dfx. The Trustee advised that he intended to object to the settlement. The conditional settlement never progressed substantially through the confirmation process. On December 20, 2010, the District Court issued an Order affirming the Bankruptcy Court's entry of summary judgment in NVIDIA's favor, and on January 19, 2011, the Trustee filed a Notice of Appeal to the United States Court of Appeals for the Ninth Circuit. Oral argument on the appeal was held on October 8, 2014. On November 6, 2014, the Ninth Circuit affirmed the District Court’s decision upholding the ruling of the Bankruptcy Court. As a result, we paid $5.6 million in related legal expenses. The case concluded on February 5, 2015 and we reversed the $25.0 million liability for additional contingent consideration and reduced the goodwill related to our 3dfx acquisition by the same amount as of January 25, 2015.

3dfx

During fiscal year 2002, we completed the purchase of certain assets from 3dfx Interactive, Inc., or 3dfx, for an aggregate purchase price of $74.2 million. On December 15, 2000, NVIDIA Corporation and one of our indirect subsidiaries entered into an Asset Purchase Agreement, or the APA, which closed on April 18, 2001, to purchase certain graphics chip assets from 3dfx.

In October 2002, 3dfx filed for Chapter 11 bankruptcy protection in the United States Bankruptcy Court for the Northern District of California. In March 2003, the Trustee appointed by the Bankruptcy Court to represent 3dfx’s bankruptcy estate served his complaint on NVIDIA. The Trustee’s complaint asserted claims for, among other things, successor liability and fraudulent transfer and sought additional payments from us. In early November 2005, NVIDIA and the Official Committee of Unsecured Creditors, or the Creditors’ Committee, agreed to a Plan of Liquidation of 3dfx, which included a conditional settlement of the Trustee’s claims against us. This conditional settlement was subject to a confirmation process through a vote of creditors and the review and approval of the Bankruptcy Court.
