Computation of Basic and Diluted Net Income (Loss) Per Share [Abstract]

Computation of basic and diluted net earnings (loss) per share

Basic net income per share is computed using the weighted average number of common shares outstanding during the period. Diluted net income per share is computed using the weighted average number of common shares, and if dilutive, potential common shares outstanding, as determined under the treasury stock and if-converted method, during the period. Potential common shares consist of common shares issuable upon the exercise of stock options, common shares issuable upon the exercise of the warrant described below and common shares issuable upon conversion of the convertible note described in Note 6 below.  The following are the share amounts utilized to compute the basic and diluted net income per share for the three months ended March 31, 2013 and 2012 (adjusted for the Reverse Stock Split):
