|
Under the Company’s equity incentive plans, employees and directors may be granted stock options, restricted stock, restricted stock units and performance awards. As of March 29, 2014, there were 480,000 shares available for future grants under the plans. |
|
Stock options. Under the Company’s equity incentive plans, employees and directors may be granted options to purchase shares of the Company’s common stock at the fair market value on the date of the grant. Options granted under these plans generally vest over three years and expire ten years from the date of the grant. Compensation expense and excess tax benefits associated with stock options for the three- and six-month periods ended March 29, 2014 and March 30, 2013 are as follows: |

|
As of March 29, 2014, the remaining unamortized compensation cost related to unvested stock option awards was $579,000, which is expected to be recognized over a weighted average period of 1.18 years. |

The fair value of each option grant is estimated on the date of grant using a Monte Carlo valuation model based upon assumptions that are evaluated and revised, as necessary, to reflect market conditions and actual historical experience. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. The dividend yield is calculated based on the Company’s annual dividend as of the option grant date. The expected volatility is derived using a term structure based on historical volatility and the volatility implied by exchange-traded options on the Company’s common stock. The expected term for options is based on the results of a Monte Carlo simulation model, using the model’s estimated fair value as an input to the Black-Scholes-Merton model, and then solving for the expected term. |
|
The estimated fair value of stock options granted during the three- and six-month periods ended March 29, 2014 and March 30, 2013 was $6.93 and $7.17, respectively, based on the following assumptions: |

Restricted stock units. Restricted stock units (“RSUs”) granted under the Company’s equity incentive plans are valued based upon the fair market value on the date of the grant and provide for a dividend equivalent payment which is included in compensation expense. The vesting period for RSUs is generally one to three years from the date of the grant. RSUs do not have voting rights.
