Earnings Per Share [Abstract]  
2. Earnings Per Share

Our earnings per share is calculated by dividing our earnings available to common stockholders by the weighted average common shares outstanding, basic and diluted.

The weighted average common shares outstanding exclude post-1992 shares of the employee stock ownership plan that have not been committed to be released. The unreleased shares, net of shares committed to be released, were 19,553 and 21,548 as of June 30, 2017 and June 30, 2016, respectively.
