2.	Accounting for Stock-Based Compensation

The following is a summary of the stock-based awards granted during the periods indicated:


	26 Weeks Ended August 3, 2013				26 Weeks Ended July 28, 2012
	Shares		Weighted Average Grant Date Fair Value		Shares		Weighted Average Grant Date Fair Value
	(In thousands, except per share data)
Stock options – time vested		457	$	7.10		—		—
Restricted stock awards – time vested		916	$	24.82		784	$	23.66
Restricted stock awards – performance based		262	$	24.82		626	$	23.66

Total stock-based awards		1,635				1,410

For stock options granted, we record stock-based compensation expense in earnings based on the grant-date fair value. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. This valuation model requires the use of subjective assumptions, including expected option life, expected volatility, expected dividend yield and expected employee forfeiture rate. We use historical data to estimate the option life, dividend yield and the employee forfeiture rate, and use historical volatility when estimating the stock price volatility. The following assumptions were used with respect to the stock options granted:


	26 Weeks Ended August 3, 2013
Volatility		46.4	%
Risk-free interest rate		1.0	%
Expected life (years)		5.6
Expected dividend yield		4.3	%

Total stock-based compensation recognized in selling, general and administrative expenses was as follows for the periods indicated:


	13 Weeks Ended				26 Weeks Ended
	August 3, 2013		July 28, 2012		August 3, 2013		July 28, 2012
	(In millions)
Stock-based compensation expense	$	6.0	$	5.5	$	11.5	$	10.4

As of August 3, 2013, the unrecognized compensation expense related to the unvested portion of our stock–based awards was $44.9 million, which is expected to be recognized over a weighted average period of 2.2 years. The total intrinsic value of options exercised during the 13 weeks ended August 3, 2013 and July 28, 2012 was $10.5 million and $0.7 million, respectively. The total intrinsic value of options exercised during the 26 weeks ended August 3, 2013 and July 28, 2012 was $21.1 million and $1.1 million, respectively.
