Fair Values Of Financial Instruments [Abstract]
Fair Values Of Financial Instruments	J. FAIR VALUES OF FINANCIAL INSTRUMENTS The carrying amounts for cash and cash equivalents, certificates of deposit, accounts receivable, and accounts payable approximate fair value due to the short-term maturity of these instruments. At December 24, 2011 and September 24, 2011, the fair value of the Company's debt was estimated at $942.8 million and $900.1 million, respectively, primarily using market yields and taking into consideration the underlying terms of the debt. Such fair value was more than the carrying value of debt at December 24, 2011 by $60.3 million and more than the carrying value of debt at September 24, 2011 by $45.7 million.

Tabular disclosure of the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments, assets, and liabilities. Such certain disclosures about the financial instruments, assets, and liabilities include: (1) the fair value of the required items together with their carrying amounts (as appropriate) and (2) the methodology and assumptions used in developing such estimates of fair value.
