Share-based Compensation [Abstract] |
Stock-Based Compensation | Stock-Based Compensation Overview of Employee Stock-Based Compensation Plans The Company currently has one equity-based compensation plan from which stock-based compensation awards can be granted to employees and directors. The Company also assumed options that were initially granted pursuant to plans adopted by companies acquired by the Company. The Company’s plans are as follows: 2004 Long-Term Incentive Compensation Plan - This plan provides for awards in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, stock units and performance units. Currently, this is the only plan under which awards can be granted. In fiscal years 2012, 2011 and 2010, the shareholders approved increases to the number of shares authorized under the plan by 4.0 million, 3.0 million and 3.0 million, respectively. As of June 24, 2012, there are 18.2 million shares authorized for issuance under the plan, and 7.1 million shares remaining for future grants. Awards issued under the plan to date include non-qualified stock options, restricted stock, stock units and performance units. The Company also has an Employee Stock Purchase Plan (the “2005 ESPP”) that provides employees with the opportunity to purchase common stock through payroll deductions. The Company established its original ESPP in 1999 and terminated it on October 31, 2005. As approved by the Company’s shareholders on November 3, 2005, the 2005 ESPP authorized issuance of up to 0.6 million shares of common stock. On October 30, 2008, the Company’s shareholders approved an amendment to the 2005 ESPP, increasing the shares authorized for issuance under the plan by an additional 0.9 million shares. On October 25, 2011, the Company's shareholders approved another amendment to the 2005 ESPP, increasing the shares authorized for issuance under the plan by an additional 1.0 million shares. As of June 24, 2012, there are 2.5 million shares authorized for issuance under the 2005 ESPP, with 1.1 million shares remaining for future issuance. The 2005 ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and originally allowed employees to purchase shares at a 15% less than the fair market value of common stock on the purchase date two times per year. The 2005 ESPP was amended in the second quarter of fiscal 2012 to increase the six-month participation period to a twelve-month participation period, divided into two equal six month purchase periods, and to provide for a look-back feature. At the end of each six-month period in April and October, employees participating in the plan may purchase the Company's common stock through the ESPP at 15% less than the fair market value of the common stock on the first day of the twelve-month participation period or the purchase date, whichever is lower. The plan amendment also provides for an automatic reset feature to start participants on a new twelve-month participation period if the share value declines during the first six-month purchase period.

As of June 24, 2012, there was $13.7 million of unrecognized compensation cost related to nonvested awards, which is expected to be recognized over a weighted average period of 2.55 years. Stock-Based Compensation Valuation and Expense The Company accounts for its employee stock-based compensation plan using the fair value method. The fair value method requires the Company to estimate the grant date fair value of its stock-based awards and amortize this fair value to compensation expense over the requisite service period or vesting term. The Company currently uses the Black-Scholes option-pricing model to estimate the fair value of the Company's stock option and ESPP awards. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. Due to the inherent limitations of option-valuation models, future events that are unpredictable and the estimation process utilized in determining the valuation of the stock-based awards, the ultimate value realized by award holders may vary significantly from the amounts expensed in the Company’s financial statements. For restricted stock and stock unit awards, the grant date fair value is based upon the market price of the Company’s common stock on the date of the grant. This fair value is then amortized to compensation expense over the requisite service period or vesting term. Stock-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those stock-based awards that are expected to vest. A forfeiture rate is estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Total stock-based compensation expense was as follows (in thousands):

The weighted average assumptions used to value stock option grants were as follows:
| Fiscal Years Ended
Stock Option Grants: | June 24, 2012 |  | June 26, 2011 |  | June 27, 2010
Risk-free interest rate | 0.47 | % |  | 0.95 | % |  | 1.76 | %
Expected life, in years | 3.63 |  |  | 3.5 |  |  | 3.7 |
Expected volatility | 51.7 | % |  | 56.7 | % |  | 48.4 | %
Dividend Yield | — |  |  | — |  |  | — |
The following describes each of these assumptions and the Company’s methodology for determining each assumption: Risk-Free Interest Rate The Company estimates the risk-free interest rate using the U.S. Treasury bill rate with a remaining term equal to the expected life of the award. Expected Life The expected life represents the period that the stock option awards are expected to be outstanding. In determining the appropriate expected life of its stock options, the Company segregates its grantees into categories based upon employee levels that are expected to be indicative of similar option-related behavior. The expected useful lives for each of these categories are then estimated giving consideration to (1) the weighted average vesting periods, (2) the contractual lives of the stock options, (3) the relationship between the exercise price and the fair market value of the Company’s common stock, (4) expected employee turnover, (5) the expected future volatility of the Company’s common stock, and (6) past and expected exercise behavior, among other factors. Expected Volatility The Company estimates expected volatility giving consideration to the expected life of the respective award, the Company’s current expected growth rate, implied volatility in traded options for its common stock, and the historical volatility of its common stock. Expected Dividend Yield The Company estimates the expected dividend yield by giving consideration to its current dividend policies as well as those anticipated in the future considering the Company’s current plans and projections. The Company does not currently calculate a discount for any post-vesting restrictions to which its awards may be subject.
