In some of our comments, we may ask you to provide us with information so we may better understand your disclosure. After reviewing this information, we may raise additional comments. Please understand that the purpose of our review process is to assist you in your compliance with the applicable disclosure requirements and to enhance the overall disclosure in your filing.

We see that you have elected to present stock based compensation expense as a separate line item on the face of the income statement. If material in future filings, please expand your discussions of the various expense categories to also discuss variances in line items inclusive of related stock compensation charges. Also, the selective financial data and quarterly information should include the allocation as well. 2. We note the significant inventory and inventory reserve balances at December 25, 2004. Please discuss these balances and the related turnover rates on a comparative basis and the reasons for the significant increase in the reserve for excess and obsolete inventory in the current year. Also, explain the basis of your conclusions regarding the recoverability of inventory as of the most recent balance sheet date. Revise future filings to clarify. Consolidated Balance Sheets, page 52 3. We see from disclosures at Note 3 that approximately $112.2 million of your marketable securities at December 25, 2004 mature after one year. Please tell us why these amounts are not classified as non-current assets in your balance sheet. Revise future filings to correctly classify your marketable securities as either current or non-current. Refer to paragraph 17 of FAS 115. Note 12. Related Party Transactions, page 76 4. Significant related party transactions should be disclosed on the face of the financial statements, pursuant to Rule 4-08(k) of Regulation S-X. Revise future filings to disclose separately the transactions with related parties or advise us why this disclosure is not necessary.
