EARNINGS PER SHARE

The following table shows the weighted average number of shares used in computing earnings per share and the effect on the weighted average number of shares of potentially dilutive securities. Potentially dilutive common stock has no effect on income available to common stockholders. There were no anti-dilutive awards during the three months ended September 30, 2018 and 2017. For the nine months ended September 30, 2018 and 2017, awards that had an anti-dilutive impact on the Company's dilutive earnings per share computation excluded from the weighted average shares outstanding were 21,000 and 29,000, respectively.
