Disclosure of Compensation Related Costs, Share-based Payments [Abstract] |
STOCK-BASED COMPENSATION | STOCK-BASED COMPENSATION The fair value of stock option awards is estimated on the date of grant using the Black-Scholes-Merton option-pricing model. There were no stock options granted in the three month period ended March 30, 2013, or in fiscal year 2012. The fair value of non-vested restricted common stock awards is generally the market value of the Company’s common stock on the date of grant. The non-vested common stock awards require the employee to fulfill certain obligations, including remaining employed by the Company for one, two or four years (the vesting period) and in certain cases also require meeting either performance criteria or the Company’s stock achieving a certain price. The performance criteria primarily consist of the achievement of the Company’s annual incentive plan goals. For non-vested restricted common stock awards which solely require the recipient to remain employed with the Company, the stock compensation expense is amortized over the anticipated service period. For non-vested restricted common stock awards which require the achievement of performance criteria, the Company reviews the probability of achieving the performance goals on a periodic basis. If the Company determines that it is probable that the performance criteria will be achieved, the amount of compensation cost derived for the performance goal is amortized over the service period. If the performance criteria are not met, no compensation cost is recognized and any previously recognized compensation cost is reversed. The Company recognizes compensation costs on a straight-line basis over the requisite service period for time-vested awards. In 2011, the Company granted 380,000 shares of phantom stock which will be settled in cash at the end of the first 10 consecutive trading day period following the grant date during which the Company’s common stock trades at a price per share equal to or greater than $5.25, prior to September 12, 2016. The vesting of the awards upon achieving a closing stock price of $5.25 for 10 consecutive days is considered a market condition which requires the Company to periodically assess the fair market value of the award, with increases or decrease in the fair market value being reflected in the statement of operations. A summary of award activity under the stock option plans as of March 30, 2013 and changes during the three month period is as follows (all options were vested as of March 30, 2013):
