The weighted-average grant date fair value of stock options granted during the three and six months endedMarch 30, 2013 was $7.80 per share and $5.83 per share, respectively. The weighted-average grant date fair value of stock options granted during the three and six months endedMarch 31, 2012 was $7.36 per share and $5.96 per share, respectively. The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value of in-the-money options that would have been received by the option holders had all option holders exercised their options at the Company's closing stock price on the date indicated.

As of March 30, 2013, unrecognized compensation expense related to stock options was $20.1 million, and is expected to be recognized over a weighted average period of 2.5 years.

Restricted Stock Units

The Company grants restricted stock units to executive officers, directors and certain management employees. These units vest over periods ranging from one to four years and are exchanged for shares of common stock at the vesting date. Compensation expense associated with these units is recognized ratably over the vesting period.

As of March 30, 2013, unrecognized compensation expense related to restricted stock units was $10.4 million, and is expected to be recognized over a weighted average period of 1.7 years. Additionally, as of March 30, 2013, unrecognized compensation expense related to performance based restricted stock units was $2.7 million. No expense has been recorded for these performance based restricted stock units to date as achievement of performance criteria is not considered probable.
