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 months ended March 31, 2012, 50,238 shares of common stock issuable upon the exercise of outstanding options, 147,482 shares issuable upon the exercise of warrants and 396,006 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 months ended March 31, 2011, 33,032 shares of common stock issuable upon the exercise of outstanding options, 176,798 shares issuable upon the exercise of warrants and 344,825 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:
