Equity Incentive Plan |
|
The Company has an Equity Incentive Plan which provides for the granting of options to purchase shares of common stock, stock awards to purchase shares at no less than 85% of the value of the shares, and stock bonuses to officers, employees, board members, certain consultants, and advisors. The Compensation Committee of the Board of Directors is authorized to administer the Equity Incentive Plan and establish the grant terms, including the grant price, vesting period and exercise date. As of December 31, 2013, the number of shares reserved for issuance under the Equity Incentive Plan totaled 991,300 shares. The Equity Incentive Plan provides for quarterly increases in the available number of authorized shares equal to the lesser of 10% of any new shares issued by the Company during the quarter immediately prior to the adjustment date or such lesser amount as the Board of Directors shall determine. Activity under the Equity Incentive Plan is as follows: |
|
| | 2013 | | 2012 | | | | | | | | | | | |
Reserved but unissued shares under the Equity Incentive Plan, beginning of year | | 480,260 | | 140,625 | | | | | | | | | | | |

Stock Options |
|
In 2013, the Company granted to certain employees 203,990 and 2,400 stock options at an exercise prices of $4.88 per share and $7.33 per share, respectively, under the Equity Incentive Plan. The stock options were issued at the grant date fair value for a contractual life of 10 years and vest over four years. As permitted by SAB 107, due to the Company’s insufficient history of option activity, management utilized the simplified approach to estimate the options’ expected term, which represents the period of time that options granted are expected to be outstanding. Expected volatility was determined through the average of a peer group of public companies. The Company estimated the forfeiture rate at the time of grant and will revise it, if necessary, in subsequent periods if actual forfeitures differ from those estimates. The Company recognizes compensation costs only for those equity awards expected to vest. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield in effect at the time of grant. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future. The Company did not grant stock options in 2012. |
|
The following weighted-average assumptions were utilized in the calculation of the fair value of the stock options: |
|
Expected life | | 6.25 years | | | | | | | | | | | | | |
Weighted average volatility | | 33 | % | | | | | | | | | | | | |
Forfeiture rate | | 13 | % | | | | | | | | | | | | |
Weighted average risk-free interest rate | | 1.31 | % | | | | | | | | | | | | |
Expected dividend rate | | - | | | | | | | | | | | | | |
|
The fair value of stock options granted estimated on the date of grant using the Black-Scholes option valuation model was $307,000. The recognized compensation expense associated with these grants in 2013 was $76,000. |
