Stock Purchase Warrants [Abstract] |
Stock Purchase Warrants [Text Block] | 6. Stock Purchase Warrants On October 10, 2014, the Company raised net proceeds of $19.1 million through the sale of 14,059,616 units at a price of $1.47 per unit to certain institutional investors in a registered direct offering. Each unit consisted of one share of the Company’s common stock and a warrant to purchase 0.5 shares of common stock. The warrants, exercisable for an aggregate of 7,029,808 shares of common stock, have an exercise price of $1.75 per share and a life of five years. The warrants vested immediately and expire October 10, 2019. The warrants issued in conjunction with the registered direct offering in October 2014 include a provision, that if the Company were to enter into a certain transaction, as defined in the agreement, the warrants would be purchased from the holder at a premium. Accordingly, the Company recorded the warrants as a liability at their estimated fair value on the issuance date and changes in estimated fair value will be recorded as non-cash income or expense in the Company’s statement of operations at each subsequent period. At March 31, 2015, the fair value of the warrant liability was $10.9 million, which represented non-cash expense of $4.2 million for the three months ended March 31, 2015. In accordance with authoritative accounting guidance, the warrant was valued on the date of grant and in subsequent periods using the Black-Scholes valuation model. The assumptions used by the Company are summarized in the following table:
|  | March 31, 2015 |  |  | December 31, 2014 |  |  | Issuance Date |
Closing stock price |  | $ | 2.19 |  |  | $ | 1.46 |  |  | $ | 1.75 |
Expected dividends |  |  | 0 | % |  |  | 0 | % |  |  | 0 | %
Expected volatility |  |  | 90 | % |  |  | 90 | % |  |  | 95 | %
Risk free interest rate |  |  | 1.26 | % |  |  | 1.59 | % |  |  | 1.39 | %
Expected life of warrant |  |  | 4.55 years |  |  |  | 4.79 years |  |  |  | 5 years |
The following table summarizes the estimated fair value of the warrant liability (in thousands):

Change in fair value of warrant liability |  |  | 4,152 |
Balance at March 31, 2015 |  | $ | 10,908 |
As of March 31, 2015, all of the warrants remained outstanding. On October 25, 2012, the Company entered into a Common Stock Purchase Agreement with certain accredited investors. As part of this agreement, the Company issued warrants to purchase 635,855 shares of common stock to the placement agent, or its permitted assigns. The warrants have an exercise price of $1.60 and a life of five years. The warrants vested immediately and expire October 25, 2017. Since these warrants were granted as part of an equity raise, the Company has treated them as a direct offering cost. The result of the transaction has no affect to equity. Warrants outstanding as of March 31, 2015 were 316,522. A summary of warrant activity for the Company for the three months ended March 31, 2015 and for the year ended December 31, 2014 is as follows:
