Share-based Payment Arrangements

The Company has various equity award plans that provide for granting stock-based awards to employees and non-employee directors of the Company. The plans provide for the granting of several available forms of stock compensation. As of January 26, 2014, the Company has granted options and restricted stock under the plans and has also issued some stock-based compensation outside of the plans, including options and restricted stock issued as inducements to join the Company.

Grant Date Fair Values and Underlying Assumptions; Contractual Terms

The Company uses the Black-Scholes pricing model to value options. For awards classified as equity, stock-based compensation cost is measured at grant date, based on the fair value of the award, and is recognized as an expense over the employee’s or director’s requisite service period. For awards classified as liabilities, stock-based compensation cost is measured at fair value at the end of each reporting date until the date of settlement, and is recognized as an expense over the employee’s or director’s requisite service period. Expected volatilities are based on historical volatility using daily and monthly stock price observations.

The following table summarizes the assumptions used in the Black-Scholes model to determine the fair value of options granted in fiscal years 2014, 2013 and 2012:



	Fiscal Year Ended
	January 26, 2014	January 27, 2013	January 29, 2012
Expected lives, in years	4.1 - 4.7	4.4 - 4.6	4.4 - 4.7
Estimated volatility	30% - 35%	38% - 41%	40% - 41%
Dividend yield	—	—	—
Risk-free interest rate	0.65% - 1.6%	0.66% - 0.73%	0.71% - 1.8%
Weighted average fair value on grant date	$8.92	$9.52	$8.43

The estimated fair value of restricted stock awards was calculated based on the market price of the Company’s common stock on the date of grant. Some of the restricted stock units awarded in fiscal year 2014 and prior years are classified as liabilities rather than equity. For awards classified as liabilities, the value of these awards is re-measured at the end of each quarter.

Stock Option Awards. The Company has historically granted stock option awards to both employees and non-employee directors. The grant date for these awards is equal to the measurement date. These awards were valued as of the measurement date and are amortized over the requisite vesting period (typically 3-4 years).

Restricted Stock. The Company has not granted any restricted stock to employees since fiscal year 2009. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date and recognized as compensation expense over the requisite vesting period (typically 3-4 years).

The following table summarizes the activity for restricted stock awards for fiscal years 2014, 2013 and 2012:

Performance Units. The Company grants performance-based vesting restricted stock units to select employees. These awards have a performance condition in addition to a service condition. The performance condition generally relates to the Company’s revenue and operating income measured against internal goals. Under the terms of these awards, assuming the highest level of performance with no cancellations due to forfeitures, the maximum number of shares that can be earned in the aggregate is 743,000. In this scenario, the maximum number of shares that could be issued thereunder would be 376,500 and the Company would have a liability accrued in the consolidated balance sheet equal to the value of 366,500 shares on the settlement date, which would be settled in cash. Only cash performance unit awards are classified as liabilities and the value of these awards is re-measured at each reporting date. At January 26, 2014, 200% of the units from the fiscal year 2011 grant vested, and 88% of the units from fiscal year 2012 are expected to vest. At January 26, 2014, the performance metrics associated with the outstanding awards issued in fiscal years 2014, 2013 and 2012 are expected to be met at a level which would result in a vest at 87%, 0%, and 88% of target, respectively.

The following table summarizes the activity for performance units during fiscal years 2014, 2013 and 2012:

The liability associated with performance units has been reduced by $3.1 million in fiscal year 2014 due to vesting in the first quarter of fiscal year 2014, forfeitures, re-measurement adjustments and change in the expected performance results.

Stock Units, Employees. The Company issues stock unit awards to employees which are expected to be settled with stock. The grant date for these awards is equal to the measurement date. These awards are valued as of the measurement date and amortized over the requisite vesting period (typically 4 years).

Stock Units, Non-Employee Directors. The Company grants stock unit awards to non-employee directors. These restricted stock units are accounted for as liabilities and accrued in the consolidated balance sheets because they are cash settled. These awards are vested after 1 year of service. However, because these awards are not typically settled until a non-employee director’s separation from service, the value of these awards is re-measured at the end of each reporting period until settlement. The following table summarizes the activity for stock unit awards for fiscal years 2014, 2013 and 2012:
