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 15,559 and 18,279 as of December 31, 2018 and 2017, respectively.
