Earnings per share
Note 7 — Earnings per share
 
Earnings per share are calculated in accordance with ASC Topic 260 (Earnings per Share), which specifies the computation, presentation and disclosure requirements for earnings per share (EPS).  It requires the presentation of basic and diluted EPS.  Basic EPS excludes all dilution and is based upon the weighted average number of common shares outstanding during the period.  Diluted EPS reflects the potential dilution that would occur if securities or other contracts to issue common stock were exercised or converted into common stock.  For the three and six months ended June 30, 2016 there were 38,000 and 26,000 anti-dilutive stock options outstanding.  For the three and six months ended June 30, 2015 there were 279,000 and 208,000 anti-dilutive stock options outstanding.
 
The following is a reconciliation of the weighted average shares outstanding for the basic and diluted EPS computations (in thousands, except share and per share data):
