The above calculation for the three months ended September 30, 2013 does not include 29,000 shares related to certain stock options because the effects of such options were anti-dilutive. For the nine months ended September 30, 2013 the calculation does not include 80,000 shares related to certain stock options because the effect of such options was anti-dilutive. There were not any anti-dilutive shares for either the three or nine months ended September 30, 2014.
