NOTE 4— STOCKHOLDERS’ EQUITY

Common Stock Warrants

The Company accounts for its common stock warrants in accordance with ASC 815 that clarifies the determination of whether an instrument (or an embedded feature) is indexed to an entity’s own stock, which would qualify for classification as liabilities. The guidance required the Company’s outstanding warrants to be classified as liabilities and to be fair valued at each reporting period, with the changes in fair value recognized as other income (expense) in the Company’s consolidated statements of operations.

During six months ended June 30, 2013, warrants to purchase 1,716,941 shares of common stock were cashless exercised for 1,153,179 shares of common stock. In addition, during the six months ended June 30, 2013, warrants to purchase 231,711 shares of common stock were exercised for net proceeds of approximately $0.6 million. As of the date of exercise of the warrants, the Company transferred the fair value of the warrants of approximately $7.5 million and $7.5 million from warrant liability into stockholders’ equity for the three and six months ended June 30, 2013, respectively.

 

At June 30, 2013 and December 31, 2012, the Company had warrants outstanding to purchase 1,312,459 and 3,058,811 shares of common stock, respectively, from the August 2008 offering.
