8. NET LOSS PER SHARE OF COMMON STOCK

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares and potential common shares outstanding during the period, so long as the inclusion of potential common shares does not result in a lower net loss per share. Potential common shares consist of restricted stock units (using the treasury stock method), the incremental common shares issuable upon the exercise of stock options (using the treasury stock method), and the conversion of the Company’s convertible preferred stock (using the if-converted method). For the three months ended March 31, 2014 and 2013, approximately 6.1 million and 4.0 million unvested restricted stock units and vested and unvested options to purchase Common Stock, respectively, were excluded from the calculation, as their effect would result in a lower net loss per share.

The following table reconciles the numerator and denominator for the calculation.
