Stockholders' Equity Note [Abstract] |
STOCKHOLDERS’ EQUITY | STOCKHOLDERS’ EQUITY COMMON STOCK At September 27, 2013, the Company is authorized to issue 525.0 million shares of common stock, par value $0.25 per share, of which 207.5 million shares are issued and 187.9 million shares outstanding. Holders of the Company’s common stock are entitled to dividends in the event declared by the Company’s Board of Directors out of funds legally available for such purpose. Dividends may not be paid on common stock unless all accrued dividends on preferred stock, if any, have been paid or declared and set aside. In the event of the Company’s liquidation, dissolution or winding up, the holders of common stock will be entitled to share pro rata in the assets remaining after payment to creditors and after payment of the liquidation preference plus any unpaid dividends to holders of any outstanding preferred stock. Each holder of the Company’s common stock is entitled to one vote for each such share outstanding in the holder’s name. No holder of common stock is entitled to cumulate votes in voting for directors. The Company’s restated certificate of incorporation as amended to date, ("the Certificate of Incorporation") provides that, unless otherwise determined by the Company’s Board of Directors, no holder of stock has any preemptive right to purchase or subscribe for any stock of any class which the Company may issue or sell. During the fiscal year ended September 27, 2013, the Company paid approximately $184.9 million (including commissions) in connection with the repurchase of 8.1 million shares of its common stock (paying an average price of $22.75 per share). Of this amount, $164.5 million of stock was repurchased under the November 8, 2012 program (which approved up to $200.0 million in repurchases) and $20.4 million was repurchased under the current $250.0 million share repurchase plan which was initiated on July 16, 2013 by the Board of Directors. This plan is valid through July 16, 2015 and allows for the repurchase of the Company's common stock on the open market or in privately negotiated transactions, in compliance with applicable securities laws and other legal requirements. As of September 27, 2013, $229.6 million remained available under the available share repurchase plan. During the fiscal year ended September 28, 2012, the Company paid approximately $12.4 million (including commissions) in connection with the repurchase of 0.8 million shares of its common stock (paying an average price of $16.54 per share). This stock repurchase program expired on August 3, 2012. PREFERRED STOCK The Company’s Certificate of Incorporation has authorized and permits the Company to issue up to 25.0 million shares of preferred stock without par value in one or more series and with rights and preferences that may be fixed or designated by the Company’s Board of Directors without any further action by the Company’s stockholders. The designation, powers, preferences, rights and qualifications, limitations and restrictions of the preferred stock of each series will be fixed by the certificate of designation relating to such series, which will specify the terms of the preferred stock. At September 27, 2013, the Company had no shares of preferred stock issued or outstanding.

The fair value of the restricted awards and units are equal to the closing market price of the Company's common stock on the date of grant. The fair value of the performance awards and units are equal to the closing market price of the Company's common stock on the date of grant and updated for the achievement of the underlying performance metrics.
| Fiscal Years Ended
| September 27, 2013 |  | September 28, 2012 |  | September 30, 2011
Expected volatility | 57.71 | % |  | 59.21 | % |  | 49.26 | %
Risk free interest rate | 1.29 | % |  | 0.52 | % |  | 0.63 | %
Dividend yield | 0.00 |  |  | 0.00 |  |  | 0.00 |
Expected option life (in years) | 4.2 |  |  | 4.1 |  |  | 4.1 |
The Company used a historical volatility calculated by the mean reversion of the weekly-adjusted closing stock price over the expected life of the options. The risk-free interest rate assumption is based upon observed treasury bill interest rates appropriate for the expected life of the Company’s employee stock options. The expected life of employee stock options represents a calculation based upon the historical exercise, cancellation and forfeiture experience for the Company across its demographic population. The Company believes that this historical data is the best estimate of the expected life of a new option and that generally all groups of the Company's employees exhibit similar behavior.
