STOCK-BASED COMPENSATION

7. STOCK-BASED COMPENSATION

The Company accounts for stock-based compensation in accordance with the fair value recognition provisions of FASB ASC Topic 718, Compensation – Stock Compensation (“ASC 718”). The Company recognized compensation expense of $3,119 and $10,977 and related income tax benefits of $1,047 and $3,591 for grants under its stock-based compensation plans in the statements of operations for the 12 and 36 weeks ended September 8, 2012, respectively. For the 12 and 36 weeks ended September 10, 2011, the Company recognized compensation expense of $2,783 and $10,160, respectively, and related income tax benefits of $908 and $3,278, respectively, for grants under its stock-based compensation plans.

Stock-based compensation expense recognized in the consolidated condensed statements of operations for the 12 and 36 weeks ended September 8, 2012 and September 10, 2011, is based on awards ultimately expected to vest and, as such, has been reduced for estimated forfeitures. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates. Forfeitures were estimated based on historical experience.

The Company estimated the fair value of employee stock options on the date of grant using the Black-Scholes model. The estimated weighted-average fair value for each option granted was $10.72 and $10.47 for the 36 weeks ended September 8, 2012 and September 10, 2011, respectively, with the following weighted-average assumptions:

 

     12 Weeks Ended     36 weeks Ended  
     September 8,     September 10,     September 8,     September 10,  
     2012     2011     2012     2011  

Expected market price volatility (1)

     36.9     38.8     37.8     38.6

Expected term (4)

(1) Based on historical volatility of the Company's common stock. The expected volatility is based on the daily percentage change in the price of the stock over the four years prior to the grant.
(2) Represents the U.S. Treasury yield curve in effect for the expected term of the option at the time of grant.
(3) Represents the Company's cash dividend yield for the expected term.
(4) Represents the period of time that options granted are expected to be outstanding. As part of the determination of the expected term, the Company concluded that all employee groups exhibit similar exercise and post-vesting termination behavior.
