Stock-Based Compensation [Abstract]

Stock-Based Compensation

G. Stock-Based Compensation

The Company measures the cost of employee services in exchange for an award of equity instruments based on the grant-date fair value of the award and recognizes the cost over the requisite service period, typically the vesting period.

The Company estimates the fair value of stock options on the grant date using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values. There is no expected dividend rate. Historical Company information was the basis for the expected volatility assumption as the Company believes that the historical volatility over the life of the option is indicative of expected volatility in the future. The risk-free interest rate is based on the U.S. Treasury zero-coupon rates with a remaining term equal to the expected term of the option. The Company also estimates forfeitures at the time of grant and revises, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Restricted stock awards are made at a value equal to the market price of the Company's common stock on the date of the grant.

On September 2, 2016, the Company's board of directors (the "Board") granted a total of 28,000 options to purchase shares of the Company's common stock to members of executive management pursuant to the Company's Amended and Restated 2011 Incentive Plan. These stock options have an exercise price equal to the grant date fair value of the Company's common stock of $3.90, a three-year life expiring on September 2, 2021, and vest as follows: 25% on the grant date; 25% on the first anniversary of the grant date; an additional 25% on the second anniversary of the grant date; and the remaining 25% on the third anniversary of the grant date. These stock options have a grant date fair value of $0.89 per option.

Compensation expense related to share-based compensation is recognized over the applicable vesting periods. As of September 30, 2016, there was approximately $38,000 of total unrecognized compensation expense related to unvested share-based compensation arrangements that will be recognized over a weighted average period of 2.2 years..
