The fully diluted weighted average shares outstanding for the three and six months ended June 30, 2018 and the corresponding calculation of fully diluted earnings per share, include approximately 117,000 and 674,000 shares, respectively that would have been issued upon the conversion of our Convertible Notes as a result of the application of the if-converted method prescribed by the FASB ASC 260, Earnings Per Share. There were approximately 1,064,000 and 1,077,000 shares for the three and six months ended June 30, 2017 that would have been issued upon conversion under the if-converted method.
For the three and six months ended June 30, 2018, approximately 645,000 and 600,000 shares, respectively, were excluded from the computation of diluted earnings per share because the inclusion of such stock options would result in an antidilutive effect. There were no stock options that were excluded from the computation of diluted earnings per share for the three and six months ended June 30, 2017.
