Stock Options

The Company's stock option plans provide employees the right to purchase common stock at the fair market value of such shares on the grant date. The Company recognizes compensation expense for such awards over the vesting period, which is generally four to five years. The contractual term of all options is ten years. For option grants made prior to 2006, the Company recognizes compensation expense using the multiple option approach. For option grants made subsequent to the adoption of ASC Topic 718, Compensation - Stock Compensation, the Company recognizes compensation expense ratably over the service period.

Assumptions used to estimate the fair value of stock options granted were as follows:

Stock option activity was as follows:

The weighted-average grant date fair value of stock options granted during 2011, 2010, and 2009 was $8.66, $6.61, and $2.41, 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 October 1, 2011, unrecognized expense related to stock options was $21.1 million, and is expected to be recognized over a weighted average period of 3.3 years.

Restricted Stock Units

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

The weighted-average grant date fair value of restricted stock units granted was $12.69, $9.80 and $1.80 in 2011, 2010 and 2009, respectively. As of October 1, 2011, unrecognized compensation expense related to restricted stock units was approximately $13.6 million, and is expected to be recognized over a weighted-average period of 2.2 years.

Activity with respect to the Company's restricted stock units was as follows:
