The weighted-average grant date fair value of stock options granted during the three and six months ended March 31, 2012 was $7.36 per share and $5.96 per share, respectively. The weighted-average grant date fair value of stock options granted during the three and six months ended April 2, 2011 was $10.52 per share and $9.00 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 31, 2012, unrecognized compensation expense related to stock options was $21.4 million, and is expected to be recognized over a weighted average period of 3.5 years.

Compensation expense associated with these units is recognized ratably over the vesting period.

As of March 31, 2012, unrecognized compensation expense related to restricted stock units was $14.1 million, and is expected to be recognized over a weighted average period of 1.8 years.
