Net loss per share [Abstract]

Net loss per share

6. Net loss per share

The Company calculates net loss per share of both basic net loss per share, which is 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 dilutive potential shares outstanding.

For the three and nine-month periods ended September 30, 2012, 46,080 shares of common stock issuable upon the exercise of outstanding options and 149,831 shares issuable upon the exercise of warrants and 414,273 shares of common stock issuable upon the conversion of the convertible preferred stock were excluded from the calculation of dilutive earnings per share because the exercise of such options and warrants and the conversion of the preferred stock would be anti-dilutive.

For the three and nine months ended September 30, 2011, 47,229 shares of common stock issuable upon the exercise of outstanding options, 189,310 shares issuable upon the exercise of warrants and 368,371 shares of common stock issuable upon the conversion of the convertible preferred stock were excluded from the calculation of dilutive earnings per share because the exercise of such options and warrants and the conversion of the preferred stock 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:
