Under the Company’s equity incentive plans, employees and directors may be granted stock options, restricted stock, restricted stock units and performance awards. Effective February 17, 2015, the shareholders of the Company approved the 2015 Equity Incentive Plan of the Company (the “2015 Plan”), which authorizes up to 900,000 shares of Company common stock for future grants under the plan.

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 28, 2015 and March 29, 2014 are as follows: |
|

|
As of March 28, 2015, the remaining unamortized compensation cost related to unvested stock option awards was $364,000, which is expected to be recognized over a weighted average period of 1.60 years. |
|
The fair value of each option award granted is estimated on the date of grant using a Monte Carlo valuation model. The estimated fair values of stock options granted during the three- and six-month periods ended March 28, 2015 and March 29, 2014 was $7.75 and $6.93 per share, respectively, based on the following assumptions: |
|

| | March 28, | | | March 29, | | | | | | | | | | | | | | |
| | 2015 | | | 2014 | | | | | | | | | | | | | | |
Risk-free interest rate | | | 1.77 | % | | | 1.56 | % | | | | | | | | | | | | | |
Dividend yield | | | 0.55 | % | | | 0.62 | % | | | | | | | | | | | | | |
Expected volatility | | | 37.39 | % | | | 41.46 | % | | | | | | | | | | | | | |
Expected term (in years) | | | 5.67 | | | | 4.94 | | | | | | | | | | | | | | |
|
The assumptions utilized in the Monte Carlo valuation model 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 was based on the U.S. Treasury yield curve in effect at the time of the grant. The dividend yield was calculated based on the Company’s annual dividend as of the option grant date. The expected volatility was 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 was 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. |

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 year from the date of the grant for RSUs granted to directors and three years from the date of the grant for RSUs granted to employees. RSUs do not have voting rights. RSU compensation expense for the three- and six-month periods ended March 28, 2015 and March 29, 2014 is as follows: |
|
