Note 6. Stock options and warrants:

 

Stock options:

 

The Company currently provides stock-based compensation to employees, directors and consultants, both under the Company's 2002 Stock Incentive Plan, as amended (the "Plan"), and non-qualified options and warrants issued outside of the Plan. During June 2014, the Company's shareholders approved amendments to the Plan to increase the number of shares reserved under the Plan from 1,912,205 to 3,673,126. The Company estimates the fair value of the share-based awards on the date of grant using the Black-Scholes option-pricing model (the "Black-Scholes model").  Using the Black-Scholes model, the value of the award that is ultimately expected to vest is recognized over the requisite service period in the statement of operations.  Option forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.  The Company attributes compensation to expense using the straight-line single option method for all options granted. 

 

The Company's determination of the estimated fair value of share-based payment awards on the date of grant is affected by the following variables and assumptions:

 


The grant date exercise price – the closing market price of the Company's common stock on the date of the grant;

Estimated option term – based on historical experience with existing option holders;

Estimated dividend rates – based on historical and anticipated dividends over the life of the option;

Term of the option – based on historical experience, grants have lives of approximately 3-5 years;

Risk-free interest rates – with maturities that approximate the expected life of the options granted;

Calculated stock price volatility – calculated over the expected life of the options granted, which is calculated based on the daily closing price of the Company's common stock over a period equal to the expected term of the option; and

Option exercise behaviors – based on actual and projected employee stock option exercises and forfeitures.

 

The Company recognized total expenses for stock-based compensation during the three-month periods ended March 31, 2015 and 2014 of $433,402 and $403,021, respectively. These expenses are included in the accompanying statements of operations for the three-month periods ended March 31, in the following categories:

The aggregate intrinsic value in the table above represents the total intrinsic value (the difference between the Company's closing stock price on March 31, 2015 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders, had all option holders been able to, and in fact had, exercised their options on March 31, 2015.

 

During the three months ended March 31, 2015, 344,000 options were issued to non-employee directors under the Plan, exercisable at an average of $1.89 per share. The options expire ten years from the date of grant and vest over one year, based upon 25% on the date of grant, and 25% on each of April 1, 2015, July 1, 2015, and October 1, 2015.

 

During the three months ended March 31, 2015, 750,500 options were issued to officers and employees under the Plan, exercisable at an average of $1.89 per share. The options expire ten years from the date of grant and vest over two years with 50% vesting upon six month anniversary of grant date and the remaining balance vesting over the following six quarters in arrears.

 

During the three months ended March 31, 2015, a total of 173,337 options that were granted under the Plan were forfeited, of which 15,002 were vested and 158,335 were unvested. The vested options were exercisable at an average of $24.17 per share and the unvested options were exercisable at an average of $2.06 per share. During the three months ended March 31, 2014, a total of 23,605 options that were granted under the Plan to employees were forfeited, of which 19,939 were vested and 3,667 were unvested. The vested options were exercisable at an average of $39.10 per share and the unvested options were exercisable at an average of $2.04 per share.

 

The total fair value of stock options granted to employees, directors and consultants that vested and became exercisable during the three months ended March 31, 2015 and 2014, was approximately $234,000 and $233,000, respectively.   Based upon the Company's experience, approximately 85% of the outstanding nonvested stock options, or approximately 941,000 options, are expected to vest in the future, under their terms.

The total fair value of stock options previously granted to an investor relations consulting firm and to an officer that vested and became exercisable during the three months ended March 31, 2015 and 2014, was zero. At March 31, 2015, there was no unrecognized cost for non-qualified options that will be recorded in the future.
