Item 4. Controls and Procedures, page 56 21. We note that your CEO and CFO concluded that your disclosure controls and procedures were "sufficiently effective to ensure that information required to be disclosed by us in this Quarterly Report on Form 10-Q was recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission`s rules." We have the following comments: * Please delete the reference to "sufficiently" as your certifying officers must reach a conclusion as to whether or not your disclosures and procedures are effective. * The description appears to be based on the definition of disclosure controls and procedures as set forth in Rule 13a-15(e) under the Exchange Act. As described, however, the description does not fully conform to the definition set forth in the rule because it does not indicate that your disclosure controls and procedures are designed to ensure that information is accumulated and communicated to your management, including your principal executive and financial officers, to allow timely decisions regarding required disclosures. Please confirm this to us and revise accordingly. Alternatively, you may simply state that your certifying officers concluded on the applicable date that your disclosure controls and procedures were effective. Please also provide us with representations regarding these comments with respect to your Forms 10-Q for the quarters ended July 1, 2005 and April 1, 2005. Finally, please confirm that you will comply with these comments in your future Exchange Act reports. *	*	*	* As appropriate, please amend your filings in response to these comments. You may wish to provide us with marked copies of the amendments to expedite our review. Please furnish a cover letter that is filed on EDGAR with your amendments that keys your responses to our comments and provides any requested information. Detailed cover letters greatly facilitate our review. Please understand that we may have additional comments after reviewing your amendments and responses to our comments. We urge all persons who are responsible for the accuracy and adequacy of the disclosure in the filings to be certain that the filings include all information required under the Securities Act and the Exchange Act and that they have provided all information investors require for an informed investment decision. Since the company and its management are in possession of all facts relating to a company`s disclosure, they are responsible for the accuracy and adequacy of the disclosures they have made. Notwithstanding our comments, in the event the company requests acceleration of the effective date of its registration statement, it should furnish a letter, at the time of such request, acknowledging that: * should the Commission or the staff, acting pursuant to delegated authority, declare the filing effective, it does not foreclose the Commission from taking any action with respect to the filing; * the action of the Commission or the staff, acting pursuant to delegated authority, in declaring the filing effective, does not relieve the company from its full responsibility for the adequacy and accuracy of the disclosure in the filing; and * the company may not assert staff comments and the declaration of effectiveness as a defense in any proceeding initiated by the Commission or any person under the federal securities laws of the United States. In addition, please be advised that the Division of Enforcement has access to all information you provide to the staff of the Division of Corporation Finance in connection with our review of your filings or in response to our comments on your filings. We will consider a written request for acceleration of the effective date of your registration statement as confirmation of the fact that those requesting acceleration are aware of their respective responsibilities under the Securities Act and the Exchange Act as they relate to the proposed public offering of the securities specified in your registration statement. We will act on the request and, pursuant to delegated authority, grant acceleration of the effective date. We direct your attention to Rules 460 and 461 regarding requesting acceleration of a registration statement. Please allow adequate time after the filing of any amendments for further review before submitting a request for acceleration.
