As a result of the Company’s purchase of a controlling interest in Ulead Systems, Inc., a publicly-traded Taiwanese company, and the time necessary for Ulead to prepare financial statements in accordance with U.S. generally accepted accounting principles, the Company concluded that it could not include the required audited consolidated financial reports for the year ended December 31, 2005 within the time period prescribed for filing the Form 10-K. In addition, this has impacted the completion of management’s assessment and the related audit procedures of the effectiveness of the Company’s internal control over financial reporting due to the diversion of personnel resources in completing the preparation of the aforementioned financial statements. The Company intends to file the Form 10-K by March 31, 2006.

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

On March 2, 2006, InterVideo furnished a Form 8-K to the Securities and Exchange Commission incorporating a press release that announced InterVideo’s financial results for the fourth quarter and fiscal year 2005. As previously reported, revenue for the fiscal year ended December 31, 2005 was $109.2 million, an increase of 47% over the $74.5 million reported during the prior year. Net income for 2005 was $3.6 million, or $0.23 per diluted share, based on 15.3 million diluted shares as compared to net income of $8.8 million, or $0.58 per diluted share, based on 15.3 million diluted shares for 2004.
