State below in reasonable detail why Forms 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.
As previously announced on October 23, 2006, the Company, at the direction of the Audit Committee of the Company’s Board of Directors, performed an initial review of selected stock options grants. In the course of that initial review, the Company discovered information that raises potential questions about the measurement dates used by the Company to account for certain stock option grants. At the recommendation of the Audit Committee, a Special Committee of the Board of Directors was formed to conduct a more detailed review of past stock option grants and related accounting matters. The Special Committee is conducting this review with the assistance of outside legal counsel.
The Special Committee has not completed its review and the Company is not currently able to determine whether adjustments will be required to the Company’s previously reported financial results. The Company will not be able to file its Form 10-Q for the third fiscal quarter ended December 30, 2006 until this review is completed. The Company intends to file this Form 10-Q as soon as practicable following the completion of the Special Committee’s review, but does not expect that it will be able to file this report on or before the fifth calendar day following the required filing date prescribed in Rule 12b-25.
As previously reported on October 30, 2006, the Division of Enforcement of the Securities and Exchange Commission (the “SEC”) recently notified the Company that it is conducting an informal investigation and requested that the Company provide the SEC certain information relating to the Company’s historical stock option practices.
Further, on January 26, 2007, the Company received notice from the staff of the Nasdaq Stock Market stating that the Nasdaq Listing Qualifications Panel has granted the company's request for continued listing on The Nasdaq Global Select Market. Cirrus Logic's continued listing is subject to the conditions that the company provides Nasdaq with certain information regarding the results of the previously announced investigation by a special committee of the company's board of directors on or about March 1, 2007, and files any delinquent periodic reports, and any required restatements, by April 18, 2007.
