Stockholders' Equity [Text Block] |
Note 8. Stockholders’ Equity At September 30, 2012, there are 500,000,000 shares of authorized common stock. Total common stock outstanding at September 30, 2012 and December 31, 2011, was 12,523,872 and 12,427,220 shares, respectively. At September 30, 2012, there were 1,524 shares reserved for future issuance, 1,034,996 stock warrants, 1,639,842 stock options outstanding and 43,876 total unvested shares of restricted stock (of which 15,290 shares of unvested restricted stock were issued but not vested and therefore not considered in our total outstanding shares on the accompanying balance sheet), all totaling 15,244,110 of total stock and stock equivalents outstanding at September 30, 2012. Stock Plan and Stock-based Compensation – Stock Options and Restricted Stock We have a stock-based compensation plan to reward for services rendered by officers, directors, employees and consultants. We have reserved 2,500,000 shares of common stock of our unissued share capital for the stock plan. Other limitations are as follows: i) No more than an aggregate of 1,250,000 shares can be granted for the purchase of restricted common shares during the term of the stock plan; ii) The maximum number of shares of common stock with respect to which options may be granted to any one person during any fiscal year may not exceed 266,667 shares; and iii) The maximum number of restricted shares that may be granted to any one person during any fiscal year may not exceed 166,667 common shares. Total stock options outstanding at September 30, 2012 and December 31, 2011, were 1,639,842 and 1,674,065, respectively of which 1,520,793 and 1,345,541 of these options were vested at September 30, 2012 and December 31, 2011, respectively. Stock option expense was approximately $0.1 million and $0.2 million for the three months ended September, 2012 and 2011, respectively, and $0.6 million and $0.8 million for the nine months ended September 30, 2012 and 2011, respectively. Stock option transactions to the employees, directors, advisory board members and consultants are summarized as follows for the nine months ended September 30, 2012 and the year ended December 31, 2011:

The following table provides certain information with respect to the above-referenced stock options that are outstanding and exercisable at December 31, 2011:
The aggregate intrinsic value of stock options outstanding at September 30, 2012 and December 31, 2011, was $0, all of which related to vested awards. Intrinsic value is calculated based on the difference between the exercise price of the underlying awards and the quoted price of our common stock as of the reporting date ($2.02 and $2.04 per share as of the close on September 30, 2012 and December 31, 2011, respectively). Restricted Stock Award ActivityThe following summarizes our restricted stock unit activity:
Scheduled vesting for outstanding restricted stock units at September 30, 2012 is as follows:
As of September 30, 2012 and December 31, 2011, there was $0.2 million and $0.4 million of net unrecognized compensation cost related to unvested restricted stock-based compensation arrangements, respectively. This compensation is recognized on a straight line basis resulting in approximately $0.1 million of the compensation expected to be expensed in the next twelve months, and the total unrecognized has a weighted average recognition period of 1.2 years. We use the historical volatility of our stock price since January 5, 2006, the date we announced that we were becoming a public company, to estimate the future volatility of our stock. At this time we do not believe that there is a better objective method to predict the future volatility of our stock. We estimate the term of our option awards based on the full term of the award. To date we have had very few exercises of our options, and those exercises have occurred just before the expiration date of the awards. Since the strike price of most of our outstanding awards is greater than the price of our stock, generally awards have expired at the end of the term. We estimate the effect of future forfeitures of our grants based on an analysis of historical forfeitures of unvested grants, as we have no better objective basis for that estimate. The expense that we have recognized related to our grants of options and restricted stock includes the estimate for future pre-vest forfeitures. We will adjust the actual expense recognized as future pre-vest forfeitures occur. We have estimated that 1.5% and 3.2% of our option and restricted stock grants respectively, will be forfeited prior to vesting. There were no stock options granted for the nine months ended September 30, 2012. Assumptions used in the Black Scholes option-pricing model for the year ended December 31, 2011 were as follows:
Stock-based compensation expense includes the expense related to (1) grants of stock options, (2) grants of restricted stock, (3) stock issued as consideration for some of the services provided by our directors and strategic advisory council members, and (4) stock issued in lieu of cash to pay bonuses to our employees and contractors. We record stock-based compensation expenses in the caption with all of our other general and administrative expenses. Grants of stock options and restricted stock are awarded to our employees, directors, consultants and board members, and we recognize the fair market value of these awards ratably as they are earned. The expense related to payments in stock for services is recognized as the services are provided. During the three months ended September 30, 2012 and 2011, approximately $0.2 million and $0.4 million was recorded as total stock-based compensation for each period, respectively, and for the nine months ended September 30, 2012 and 2011, approximately $0.8 million and $1.1 million was recorded as total stock-based compensation for each period, respectively. Stock-based compensation expense is recorded under the caption general and administrative expenses in the accompanying consolidated statement of operations. Common Stock reserved for Future Issuance Common stock reserved for future issuance at September 30, 2012, consists of:
