Employee Stock Options
The Company maintains an equity incentive plan, (the Plan). The Plan was established in 2010 as an incentive plan for officers, employees, non-employee directors, prospective employees and other key persons. It is anticipated that providing such persons with a direct stake in the Companys welfare will assure a better alignment of their interests with those of the Company and its stockholders.
The following table summarizes the changes in options outstanding and the related prices for the shares of the Companys common stock issued to employees of the Company under the Plan.
Transactions involving stock options issued to employees are summarized as follows:
The expected life of awards granted represents the period of time that they are expected to be outstanding. We determine the expected life based on historical experience with similar awards, giving consideration to the contractual terms, vesting schedules, exercise patterns and pre-vesting and post-vesting forfeitures. We estimate the volatility of our common stock based on the calculated historical volatility of our own common stock using the trailing 24 months of share price data prior to the date of the award. We base the risk-free interest rate used in the Black-Scholes option valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award. We have not paid any cash dividends on our common stock and do not anticipate paying any cash dividends in the foreseeable future. Consequently, we use an expected dividend yield of zero in the Black-Scholes option valuation model. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation for those awards that are expected to vest. In accordance with ASC 718-10, we adjust share-based compensation for changes to the estimate of expected equity award forfeitures based on actual forfeiture experience.
There were 504,583 and 615,642 options granted and no options exercised during the six months ended June 30, 2013 and 2012, respectively. Total stock-based compensation expense in connection with options granted to employees recognized in the condensed consolidated statements of operations for the three and six months ended June 30, 2013 and 2012 was $83,496 and $97,504 and $85,519 and $103,669, respectively.
