Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
Stock-Based Awards | Stock-Based Awards The Company has certain stock-based compensation plans which provide for the grants of stock-based awards, including stock options, restricted shares, performance shares, restricted share units, performance share units, and stock appreciation rights. Compensation expense for stock-based awards is based on fair value at the measurement date and fluctuates over time as a result of the Company's performance, as measured by the criteria set forth in the performance-based awards, as well as the vesting period of all stock-based awards. The expense is included in general and administrative expenses in the condensed consolidated statements of operations and the amount of expense ultimately recognized is based on the number of awards that actually vest. For performance share units ("Performance RSUs"), the Company evaluates compensation expense quarterly and recognizes expense for performance-based awards only if management determines it is probable that performance criteria for the awards will be met. Accordingly, the amount of compensation expense recognized during any fiscal year may not be representative of future stock-based compensation expense. Stock-based compensation expense and the related tax benefit recognized related to stock options and restricted share units during the three and nine months ended April 25, 2015 and April 26, 2014 were as follows:
| For the Three Months Ended |  | For the Nine Months Ended

Stock-based compensation | $ | 3,219 |  |  | $ | 2,671 |  |  | $ | 10,773 |  |  | $ | 9,721 |
Tax benefit recognized in the statement of operations | $ | 1,248 |  |  | $ | 1,071 |  |  | $ | 4,221 |  |  | $ | 3,736 |
As of April 25, 2015, unrecognized compensation expense related to stock options, time-based restricted share units ("RSUs") and target Performance RSUs (based on the Company's estimate of performance goal achievement) was $3.5 million, $6.9 million, and $15.5 million, respectively. This expense will be recognized over a weighted-average period of 2.7 years, 2.5 years and 1.6 years, respectively, which is based on the average remaining service periods of the awards. As of April 25, 2015, the Company may recognize an additional $5.3 million in compensation expense related to Performance RSUs if the maximum amount of restricted share units are earned based on certain performance goals being met.
