(4) Net Loss Per Share

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 and warrants (using the if-converted method). Such warrants to purchase Common Stock all expired during the fourth quarter of 2012. For the years ended December 31, 2013, 2012 and 2011, approximately 4.2 million, 3.3 million and 4.5 million unvested restricted stock units, vested and unvested options and warrants 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.
