	Unrecognized Compensation Expense		Weighted- Average Period (in years)

In accordance with the applicable accounting guidance for stock-based compensation, the compensation expense for stock-based awards is reduced by an estimate for forfeitures and is recognized over the requisite service period of the respective awards. To the extent that the actual forfeitures differ from the estimated forfeitures, the Company records the difference in the period that the awards vest. The Company estimates the forward-looking forfeiture rate, using the Company’s historical forfeiture rates, annually during the second fiscal quarter, and whenever events occur or facts and circumstances indicate that the current forfeiture rate estimate is significantly different from historical forfeitures. Changes in the estimated forfeiture rates and differences between the estimated forfeiture rates and actual forfeiture rates may result in significant increases or decreases in stock-based compensation expense from period to period.

Based on the results of the annual forfeiture rate analysis performed during the second fiscal quarter of 2015, the Company recorded a cumulative adjustment to reduce stock-based compensation expense by $5.6 million during the three months ended May 2, 2015, to reflect the effect of the change in the estimated forfeiture rates.

There was no significant impact related to the change in the estimated forfeiture rates during the three months ended May 3, 2014.
