Stock-Based Compensation

STOCK-BASED COMPENSATION

Stock-based compensation cost recognized in operating results (included in selling, general, and administrative expenses) for the three months ended March 31, 2013 and March 25, 2012 was $2.0 million and $1.8 million ($2.0 million and $1.7 million, net of tax), respectively. The associated actual tax benefit realized for the tax deduction from option exercises of share-based payment units and awards released equaled $0.1 million and $0.6 million for the three months ended March 31, 2013 and March 25, 2012, respectively.

Stock Options

Option activity under the principal option plans as of March 31, 2013 and changes during the three months ended March 31, 2013 were as follows:

	Number of Shares		Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value (in thousands)
Outstanding at December 30, 2012	2,744,057		$	17.24	5.01	$	1,321
Granted	100,367		12.23
Exercised	(82,854	)	12.03
Forfeited or expired	(23,383	)	12.24
Outstanding at March 31, 2013	2,738,187		$	17.26	5.01	$	3,046
Vested and expected to vest at March 31, 2013	2,558,300		$	17.78	4.71	$	2,446
Exercisable at March 31, 2013	2,141,920		$	19.28	3.83	$	1,113

The aggregate intrinsic value in the table above represents the total pre-tax intrinsic value (the difference between our closing stock price on the last trading day of the first quarter of fiscal 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders had all option holders exercised their options on March 31, 2013. This amount changes based on the fair market value of our stock. The total intrinsic value of options exercised for the three months ended March 31, 2013 and March 25, 2012 was $0.1 million and $0.1 million, respectively.

As of March 31, 2013, $1.4 million of total unrecognized compensation cost related to stock options is expected to be recognized over a weighted-average period of 2.2 years.

The fair value of share-based payment units was estimated using the Black-Scholes option pricing model. The table below presents the weighted-average expected life in years. The expected life computation is based on historical exercise patterns and post-vesting termination behavior. Volatility is determined using changes in historical stock prices. The interest rate for periods within the expected life of the award is based on the U.S. Treasury yield curve in effect at the time of grant. The assumptions and weighted-average fair values were as follows:

Quarter (13 weeks) ended	March 31, 2013		March 25, 2012
Weighted-average fair value of grants	5.42		5.39
Valuation assumptions:
Expected dividend yield	0.00	%	0.00	%
Expected volatility	50.85	%	51.83	%
Expected life (in years)	5.07		5.06
Risk-free interest rate	0.792	%	0.893	%

Restricted Stock Units

Nonvested restricted stock units as of March 31, 2013 and changes during the three months ended March 31, 2013 were as follows:

	Number of Shares		Weighted- Average Vest Date (in years)	Weighted- Average Grant Date Fair Value
Nonvested at December 30, 2012	563,106		0.79	$	21.14
Granted	416,098			$	11.06
Vested	(106,227	)		$	11.99
Forfeited	(7,186	)		$	13.55
Nonvested at March 31, 2013	865,791		1.03	$	17.48
Vested and expected to vest at March 31, 2013	778,925		0.92
Vested at March 31, 2013	—		—

The total fair value of restricted stock awards vested during the first three months of 2013 was $1.3 million as compared to $1.6 million in the first three months of 2012. As of March 31, 2013, there was $4.3 million of unrecognized stock-based compensation expense related to nonvested restricted stock units. That cost is expected to be recognized over a weighted-average period of 1.6 years.

Other Compensation Arrangements

On March 15, 2010, we initiated a plan in which time-vested cash unit awards were granted to eligible employees. The time-vested cash unit awards under this plan vest evenly over two or three years from the date of grant. The total amount accrued related to the plan equaled $0.4 million as of March 31, 2013, of which $0.3 million was expensed for the three months ended March 31, 2013. The total amount accrued related to the plan equaled $0.3 million as of March 25, 2012, of which $0.2 million was expensed for the three months ended March 25, 2012. The associated liability is included in Accrued Compensation and Related Taxes in the accompanying Consolidated Balance Sheets.
