LOSS PER COMMON SHARE

7. LOSS PER COMMON SHARE

The Company computes basic net loss per share using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed by dividing the net loss for the period by the weighted average number of common and common equivalent shares outstanding during the period. Additionally, potentially dilutive securities, composed of incremental common shares issuable upon the exercise of stock options and warrants and the vesting of RSUs, are excluded from the diluted loss per share calculation because of their anti-dilutive effect.

For the three and six months ended June 30, 2014, the Company realized a net loss of $13.4 million and $25.2 million, respectively. Potentially dilutive securities totaled approximately 2.6 million and 2.8 million, respectively, for the three and six months ended June 30, 2014. Options to purchase approximately 0.9 million shares of common stock were outstanding during each of the three and six month periods ended June 30, 2014, with an exercise price greater than the average market price of the underlying common shares.

For the three and six months ended June 30, 2013, the Company realized a net loss of $12.2 million and $24.3 million, respectively. Potentially dilutive securities totaled approximately 2.3 million and 2.1 million, respectively, for the three and six months ended June 30, 2013. Options to purchase approximately 0.3 million and 0.6 million shares of common stock were outstanding during the three and six months ended June 30, 2013, respectively, with an exercise price greater than the average market price of the underlying common shares.
