Net loss per share [Abstract]

Net loss per share

5. Net loss per share

The Company calculates basic net loss per share, based on the weighted average number of shares outstanding, and when applicable, diluted income per share, which is based on the weighted average number of shares and potential dilutive shares outstanding.

For the six months ended June 30, 2013, 70,472 shares of Common Stock subject to outstanding options, 7,079 shares of Series A-1 Preferred Stock, 243,796 shares of Series B Preferred Stock, 194,888 shares of Series C Preferred Stock, 62,818 shares of Series D-1 Convertible Preferred Stock (the "Series D-1 Preferred Stock") and 87,997 shares of Series D-2 Convertible Preferred Stock (the "Series D-2 Preferred Stock" and, together with the Series D-1 Preferred Stock, the "Series D Preferred Stock") on an as converted basis and 135,359 shares issuable upon exercise of warrants were excluded from the calculation of dilutive earnings per share as the exercise of such options and warrants would be anti-dilutive.

For the six months ended June 30, 2012, 47,903 shares of Common Stock subject to outstanding options, 6,540 shares of Series A-1 Preferred Stock, 220,865 shares of Series B Preferred Stock and 176,600 shares of Series C Preferred Stock on an as converted basis and 149,893 shares issuable upon exercise of warrants were excluded from the calculation of dilutive earnings per share as the exercise of such options and warrants would be anti-dilutive.

The following table is a reconciliation of the numerator (net loss) and the denominator (number of shares) used in the basic and diluted EPS calculations and sets forth potential shares of common stock that are not included in the diluted net loss per share calculation as the effect is antidilutive:
