Net loss per share [Abstract]

Net loss per share

6. 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 nine-months ended September 30, 2013, 70,017 shares of Common Stock subject to outstanding options, 7,222 shares of Series A-1 Preferred Stock, 249,941 shares of Series B Preferred Stock, 199,801 shares of Series C Preferred Stock, 64,401 shares of Series D-1 Convertible Preferred Stock (the "Series D-1 Preferred Stock") and 90,215 shares of Series D-2 Convertible Preferred Stock (the "Series D-2 Preferred Stock") on an as converted basis and 129,335 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 nine-months ended September 30, 2012, 46,080 shares of Common Stock subject to outstanding options, 6,540 shares of Series A-1 Preferred Stock, 226,434 shares of Series B Preferred Stock and 181,010 shares of Series C Preferred Stock on an as converted basis and 149,831 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:
