Item 2.01 Completion of Acquisition or Disposition of Assets.

On May 4, 2012, Trident Microsystems, Inc., a Delaware corporation (“Trident”), closed on the sale of certain of its assets pursuant to the previously disclosed Asset Purchase Agreement dated as of March 23, 2012, as amended, by and among Trident, certain of Trident’s wholly-owned subsidiaries and Sigma Designs, Inc., a California corporation (“Sigma”). The sale was conducted pursuant to the provisions of Sections 105, 363 and 365 of Chapter 11, Title 11 of the United States Bankruptcy Code.

The aggregate consideration received by Trident for the purchase of Trident’s Digital Television (DTV) Business assets consisted of $21.0 million plus additional cash consideration as a result of the closing current asset balance of the DTV business, which exceeded a target current asset amount. The current asset adjustment resulted in an additional cash payment of $21.2 million by Sigma, and the receipt by Sigma of $19.5 million of inventory at various stages of completion, $13.4 million of accounts receivable, $5.5 million of equipment and various assets, $2.1 million of prepaid expenses and $1.7 million of development projects in process.

On May 7, 2012, Sigma issued a press release relating to the foregoing matters, the text of which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.
