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 three months ended March 31, 2013, 70,270 shares of Common Stock subject to outstanding options, 6,941 shares of Series A-1 Preferred Stock, 237,866 shares of Series B Preferred Stock, 190,146 shares of Series C Preferred Stock, 51,193 shares of Series D-1 Convertible Preferred Stock (the "Series D-1 Preferred Stock") and 67,682 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 149,022 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 three months ended March 31, 2012, 50,238 shares of Common Stock subject to outstanding options, 6,412 shares of Series A-1 Preferred Stock, 215,492 shares of Series B Preferred Stock and 173,952 shares of Series C Preferred Stock on an as converted basis and 147,482 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:
