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, the 2013 Long-Term Incentive Compensation Plan (2013 LTIP), from which stock-based compensation awards can be granted to employees and directors. At June 25, 2017, there were 10.6 million shares authorized for issuance under the plan and 6.2 million shares remaining for future grants. The 2013 LTIP provides for awards in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance shares, performance units and other awards. The Company has other equity-based compensation plans that have been terminated so that no future grants can be made under those plans, but under which stock options, restricted stock and restricted stock units are currently outstanding. The Company’s stock-based awards can be either service-based or performance-based. Performance-based conditions are generally tied to future financial and/or operating performance of the Company. The compensation expense with respect to performance-based grants is recognized if the Company believes it is probable that the performance condition will be achieved. The Company reassesses the probability of the achievement of the performance condition at each reporting period, and adjusts the compensation expense for subsequent changes in the estimate or actual outcome. As with non-performance based awards, compensation expense is recognized over the vesting period. The vesting period runs from the date of grant to the expected date that the performance objective is likely to be achieved. The Company also has an Employee Stock Purchase Plan (ESPP) that provides employees with the opportunity to purchase common stock at a discount. At June 25, 2017, there were 4.5 million shares authorized for issuance under the ESPP, as amended, with 0.1 million shares remaining for future issuance. The ESPP limits employee contributions to 15% of each employee’s compensation (as defined in the plan) and allows employees to purchase shares at a 15% discount to the fair market value of common stock on the purchase date two times per year. The ESPP provides for a twelve-month participation period, divided into two equal six-month purchase periods, and also provides for a look-back feature. At the end of each six-month period in April and October, participants purchase the Company’s common stock through the ESPP at a 15% discount to 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 also provides for an automatic reset feature to start participants on a new twelve-month participation period if the fair market value of common stock declines during the first six-month purchase period.

As of June 25, 2017, there was $37.6 million of unrecognized compensation cost related to nonvested awards, which is expected to be recognized over a weighted average period of 2.38 years. Stock-Based Compensation Valuation and Expense The Company accounts for its employee stock-based compensation plans 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 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 RSAs and RSUs, 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 recognized net of estimated forfeitures such that expense is recognized 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 25, 2017 |  | June 26, 2016 |  | June 28, 2015
Risk-free interest rate | 1.06 | % |  | 1.18 | % |  | 1.17 | %
Expected life, in years | 3.80 |  |  | 3.66 |  |  | 3.54 |
Expected volatility | 42.4 | % |  | 43.3 | % |  | 45.2 | %
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.
