PART III — NARRATIVE

State below in reasonable detail why Form 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period. (Attach extra sheets if needed.)

As previously disclosed, on January 4, 2012 Trident and its wholly-owned subsidiary, Trident Microsystems (Far East) Ltd, a Cayman Islands Corporation, (together with Trident “the Debtors”) filed voluntary petitions (the “Bankruptcy Filing”) for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the District of Delaware.

In the months leading up to and since the Bankruptcy Filing, the Company has been principally engaged in addressing bankruptcy-related matters, negotiating with suppliers, creditors and potential strategic partners, and reformulating its business strategy. The Company’s financial, accounting and administrative personnel have devoted substantially all of their time to the maintenance of the Company’s ongoing operations, including the development and implementation of the Company’s post-petition strategy and negotiations with potential purchasers of assets. The Company’s ability to address all of these matters concurrently has been adversely affected by a substantial reduction in force recently executed by the Company.

The Bankruptcy Filing came at a time during which year-end close procedures would normally be conducted. As a result of the increased burdens placed upon the Company’s financial, accounting and administrative staff, the diversion of the Company’s financial resources towards the efforts described above, and the subsequent changes in the Company’s operations and anticipated operations, the Company has been unable to timely complete the preparation of its Annual Report on Form 10-K.
