Earnings per Share

Basic earnings per share is based upon the weighted average common shares outstanding during each period.  Diluted earnings per share is based on the basic weighted earnings per share with additional weighted common shares for common stock equivalents.

A reconciliation of the numerator (net income) and denominator (weighted average number of shares outstanding of the basic and diluted earnings per share ("EPS")) for the three months ended March 31, 2013 and March 31, 2012 is as follows (in thousands, except per share data):
