Share-Based Compensation [Abstract]
Stock-Based Compensation	Note 4: Stock-Based Compensation Restricted Stock Units Restricted stock unit grants are designed to attract and retain employees, and to better align employee interests with those of the Company’s stockholders. For a select group of employees, up to 40% of their annual bonus is settled with fully vested restricted stock unit awards. Under these fully vested restricted stock unit awards, the holder of each award has the right to receive one share of the Company’s common stock for each fully vested restricted stock unit four years from the date of grant. Each individual who receives a fully vested restricted stock unit award is also granted a matching number of unvested restricted stock unit awards. Unvested restricted stock unit awards are also granted for select new hires and promotions. These unvested restricted stock unit awards generally cliff vest four years from the date of grant, at which time the holder of each award will have the right to receive one share of the Company’s common stock for each restricted stock unit award provided the holder of each award has met certain employment conditions. In the case of retirement at 59½ years or older, all unvested restricted stock unit awards will continue to vest, provided that the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company. The value of these restricted stock unit awards is determined based on the market price of the Company’s common stock on the date of grant. The value of fully vested restricted stock unit awards issued is recorded as a reduction to accrued bonuses. The portion of bonus expense that the Company expects to settle with fully vested restricted stock unit awards is recorded as stock-based compensation during the period the bonus is earned. The Company recorded stock-based compensation expense associated with accrued bonus awards of $1,625,000 and $1,659,000 during the three months ended June 28, 2013 and June 29, 2012, respectively. For the six months ended June 28, 2013 and June 29, 2012, the Company recorded stock-based compensation expense associated with accrued bonus awards of $3,138,000 and $3,133,000, respectively. The value of the unvested restricted stock unit awards granted is recognized on a straight-line basis over the shorter of the four-year vesting period or the period between the grant date and the date the award recipient turns 59½. If the award recipient is 59½ years or older on the date of grant, the value of the entire award is expensed upon grant. The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $1,166,000 and $908,000 during the three months ended June 28, 2013 and June 29, 2012, respectively. The Company recorded stock-based compensation expense associated with the unvested restricted stock unit awards of $4,324,000 and $3,739,000 during the six months ended June 28, 2013 and June 29, 2012, respectively. Stock Options Stock options are granted for terms of ten years and generally vest 25% per year over a four-year period from the grant date. For options granted on or after January 1, 2012, all unvested stock option awards will continue to vest in the case of retirement at 59½ or older, provided that the holder of each award does all consulting work through the Company and does not become an employee for a past or present client, beneficial party or competitor of the Company. The Company grants options at exercise prices equal to the fair value of the Company’s common stock on the date of grant. The Company recorded stock-based compensation expense of $249,000 and $160,000 during the three months ended June 28, 2013 and June 29, 2012, respectively, associated with stock option grants. The Company recorded stock-based compensation expense of $869,000 and $312,000 during the six months ended June 28, 2013 and June 29, 2012, respectively, associated with stock option grants. The Company uses the Black-Scholes option-pricing model to determine the fair value of options granted. The determination of the fair value of stock-based awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding a number of complex and subjective variables. These variables include expected stock price volatility over the term of the award, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company used historical exercise and post-vesting forfeiture and expiration data to estimate the expected term of options granted. The historical volatility of the Company’s common stock over a period of time equal to the expected term of the options granted was used to estimate expected volatility. The risk-free interest rate used in the option-pricing model was based on United States Treasury zero-coupon issues with remaining terms similar to the expected term on the options. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data was used to estimate pre-vesting option forfeitures and stock-based compensation expense was recorded only for those awards that are expected to vest. All share-based payment awards are recognized on a straight-line basis over the requisite service periods of the awards.
