The following table presents information necessary to calculate net income per share for the three and nine months ended September 30, 2014 and 2013 as well as potentially dilutive securities excluded from the weighted average number of diluted common shares outstanding because their inclusion would have been anti-dilutive (in thousands, except per share amounts):
