15. Stock Incentive Plans

        In 2007, stockholders approved the 2007 Performance Incentive Plan which was amended and restated in 2008 and amended and restated again in 2011 (the "2007 Stock Plan"). The 2007 Stock Plan authorizes the issuance of stock options, stock appreciation rights (SARs), restricted stock, stock variable compensation and other forms of awards granted or denominated in the Company's common stock or units of the Company's common stock, as well as cash variable compensation awards pursuant to the plan. Persons eligible to receive awards under the 2007 Stock Plan include officers and employees of the Company and any of the Company's subsidiaries, directors of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. The maximum number of shares of the Company's common stock that may be issued or transferred pursuant to awards under the 2007 Stock Plan is 2,074,600 shares. Vesting of the awards under the 2007 Stock Plan is determined at the date of grant by the plan administrator. Each award granted under the 2007 Stock Plan fully vests, becomes exercisable and/or payable, as applicable, upon a change in control event. However, unless the individual award agreement provides otherwise, with respect to executive and certain other high level officers of the Company, upon the occurrence of a change in control, no award will vest unless such officers' employment with the Company is terminated by the Company without cause during the two-year period following such change in control event. Each award expires on such date as shall be determined at the date of grant, however, the maximum term of options, SARs and other rights to acquire common stock under the plan is ten years after the initial date of the award, subject to provisions for further deferred payment in certain circumstances. The 2007 Stock Plan terminates on April 4, 2021, unless terminated earlier by the Company's board of directors. As of December 30, 2012, options to acquire a total of 578,430 shares of the Company's common stock remained outstanding under this plan of which 308,279 were vested.

        The Company has four other stock-based compensation plans: the 1996 Stock Option Plan (the 1996 Stock Plan), the 2000 Management Performance Common Stock Option Plan (the 2000 Stock Plan), the 2002 Incentive Stock Option Plan (2002 Stock Plan) and the 2004 Performance Incentive Plan (the 2004 Stock Plan). No further grants can be made under these plans. In general, options granted under these plans were issued at the estimated fair market value at the date of grant. Vesting of awards under these plans were generally time based over a period of one to four years; however, in some cases, options under these plans vested based on the attainment of certain financial results. As of December 30, 2012, options to acquire a total of 126,514 of the Company's common stock remain outstanding under these plans of which all are fully vested. Options granted under these plans expire within ten years from the date of grant. Canceled options revert back to the 2007 Stock Plan for potential reissuance.

        Total stock-based compensation costs recognized in fiscal 2012, 2011, and 2010 were $3.8 million, $3.3 million, and $4.1 million, respectively, with related income tax benefits of $1.5 million, $1.3 million, and $1.7 million, respectively. As of December 30, 2012, there was $4.2 million of total unrecognized compensation cost, excluding estimated forfeitures, which is expected to be recognized over the weighted average remaining vesting period of approximately 1.2 years for stock options, 0.2 year for the non-vested common shares, 1.2 years for the restricted stock units, and 0.5 years for the performance stock units.

Stock Options

        The table below summarizes the status of the Company's stock option plans (in thousands, except per share data and exercise price):

        The estimated fair value of each option granted is calculated using the Black-Scholes multiple option-pricing model. The average assumptions used in the model were as follows:

        The risk-free interest rate was based on the rate for zero coupon U.S. Government issues with a remaining term similar to the expected life. The expected life of the options represents the period of time the options are expected to be outstanding and is based on historical trends and team member exercise patterns. The expected stock price volatility represents an average of the Company's historical volatility measured over a period approximating the expected life. The dividend yield assumption is based on the Company's history and expectations of dividend payouts.

Restricted Stock

        During the fiscal years ended December 30, 2012 and December 25, 2011, the Company did not issue restricted stock as permitted under the 2007 Stock Plan. In the past, the Company has granted restricted stock to its directors, executive officers and other key employees. The restricted shares granted to directors were generally subject to a three year vesting requirement. The restricted shares granted to executive officers and other key employees were generally subject to a four year graded vesting requirement. The fair value of the non-vested common shares is based on the grant date market value of the common shares.

Time-Based RSUs

        During fiscal years 2012 and 2011, the Company issued time-based restricted stock units (RSUs) to certain employees as permitted under the 2007 Stock Plan. The Company can grant RSUs to its directors, executive officers and other key employees. The RSUs vest in equal installments over four years and upon vesting, one share of the Company's common stock is issued for each RSU. The fair value of each RSU granted is equal to the market price of the Company's stock at the date of grant.

        The table below summarizes the status of the Company's time-based RSUs under the 2007 Stock Plan (shares in thousands):

Performance-Based RSUs

        There were no performance-based restricted stock units awarded in fiscal 2012 or 2011. In March and September 2010, the Company granted performance-based restricted stock units ("PSUs") to executives and other key employees. These PSUs are subject to company performance metrics based on Total Shareholder Return and measure the overall stock price performance of the Company to the stock price performance of a selected industry peer group, thus resulting in a market condition. The actual number of PSUs subject to the awards will be determined at the end of the performance period based on these performance metrics. The fair value of the PSUs was calculated using the Monte Carlo valuation method. This method utilizes multiple input variables to determine the probability of the Company achieving the market condition and the fair value of the awards. These awards have a three-year performance period and are classified as equity as each unit is convertible into one share of the Company's common stock upon vesting. Compensation expense is recognized on a straight-line basis over the requisite service period (or to an employee's eligible retirement date, if earlier).

        During fiscal year 2012, the Company granted no PSUs under the 2007 Stock Plan. At the end of fiscal year 2011, the Company had 37,000 PSUs outstanding. During the fiscal year 2012, the Company cancelled 2,000 PSUs, resulting in an outstanding balance of 35,000 PSUs as of the end of fiscal year 2012.

Long-Term Cash Incentive Plan

        In 2011, the Company began a long-term cash incentive program. The long-term cash incentive plan is based on operational metrics with a three-year performance period. The awards cliff vest at the end of each three-year performance cycle. In 2012 and 2011, the Company recorded approximately $1.5 million and $0.4 million related to this program, respectively, in Selling, General and Administrative expense.
