Stock-Based Compensation

The Company’s 2007 Long-Term Equity Incentive Plan, as amended, approved in May 2008 (the "2007 Plan"), authorizes the issuance of up to 4,500,000 shares of the Company’s common stock. Upon approval of the 2007 Plan, the Company ceased making awards under its prior equity plans, including the Company’s 2001 Long-Term Equity Incentive Plan. Unused shares previously authorized under prior plans have been rolled over into the 2007 Plan and increased the total number of shares authorized for issuance under the 2007 Plan by 1,040,000 shares in 2013.

The Company’s outstanding unvested stock options have maximum contractual terms of up to six years, principally vest ratably over four years and are granted at exercise prices equal to the market price of the Company’s common stock on the date of grant. The Company’s outstanding stock options are exercisable into shares of the Company’s common stock. The Company’s outstanding restricted share units ("RSUs") principally vest ratably over four years. Upon vesting, RSUs convert into shares of the Company’s common stock. The Company currently issues authorized shares of common stock upon vesting of restricted shares or the exercise of other equity awards. The Company has no outstanding stock appreciation rights.

The Company measures the cost of employee services received in exchange for an award of equity instruments, including grants of employee stock options, RSUs and performance share units ("PSUs"), based on the fair value of the award at the date of grant in accordance with the modified prospective method. The Company uses the Black-Scholes model for purposes of determining the fair value of stock options granted and recognizes compensation costs ratably over the requisite service period for each separately vesting portion of the award, net of estimated forfeitures. The Black-Scholes model has limitations on its effectiveness including that it was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable and that the model requires the use of parameters, such as stock price volatility that must be estimated from historical data and other market information. The Company’s stock option awards to employees have characteristics significantly different from those of traded options and parameter estimation methodologies can materially affect fair value estimates. Stock-based compensation is expensed on a straight-line basis over the service period of the awards, with the exception of PSUs, which are expensed based on the probability that the performance condition will be satisfied.

Total stock-based compensation expense recognized in selling, general and administrative expenses in the Company’s consolidated statement of operations was $1.6 million, $2.4 million and $3.7 million for the years ended 2015, 2014 and 2013, respectively. The income tax benefits related to the Company’s stock-based compensation expense were $0.4 million, $0.6 million and $0.7 million for the years ended 2015, 2014 and 2013, respectively.

As of January 2, 2016, there was approximately $2.6 million of total unrecognized compensation cost related to unvested stock-based compensation grants, which is expected to be amortized over a weighted average period of 2.3 years.

__________________________


(1)	Intrinsic value for purposes of this table represents the amount by which the fair value of the underlying stock, based on the respective market prices as of the years ended 2015, 2014 and 2013, or, if exercised, the exercise dates, exceeds the exercise prices of the respective options.

The weighted average grant date fair value of stock options granted during 2015 and 2013, were at exercise prices equal to the market price of the stock on the grant dates, as calculated under the Black-Scholes model with the weighted average assumptions as follows:



	2015			2013
Weighted average fair value of option grants during the year	$	0.86		$	1.01
Assumptions:
Expected option life in years	4.25			4.25
Risk-free interest rate	1.24		%	0.50		%
Expected volatility	43.0		%	65.7		%
Expected dividend yield	0.0		%	0.0		%

The risk-free interest rate represents the United States Treasury Bond constant maturity yield approximating the expected option life of stock options granted during the period. The expected option life represents the period of time that the stock options granted during the period are expected to be outstanding, based on the mid-point between the vesting date and contractual expiration date of the option. The expected volatility is based on the historical market price volatility of the Company’s common stock for the expected term of the options, adjusted for expected mean reversion.

There were no stock options granted during 2014.
