5. Earnings per Share (“EPS”)

Basic EPS is calculated by dividing net income by the weighted average number of shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic earnings per share. Diluted EPS is calculated by dividing net income by the weighted average number of shares outstanding plus the dilutive effect, if any, of outstanding stock options, stock appreciation rights (“SAR’s”), restricted shares, and restricted stock units using the treasury stock method.

The following table provides share information used in the calculation of the Company's basic and diluted earnings per share:

Stock options to purchase 129,540 shares, 21,326 shares, and 131,273 shares for 2014, 2013, and 2012, respectively, were excluded from the computation of diluted EPS as their effect would have been anti-dilutive.
