Earnings Per Share

The Company reports earnings per share in accordance with ASC 260, Earnings Per Share, which establishes standards for computing and presenting earnings per share. Basic earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding and the number of dilutive potential common share equivalents during the period. Under the treasury stock method, unexercised “in-the-money” stock options are assumed to be exercised at the beginning of the period or at issuance, if later. The assumed proceeds are then used to purchase common shares at the average market price during the period.

Basic and diluted earnings per share for the three months ended March 31, 2014 and 2013 are as follows:

Equity awards of 87,126 and 555,001 shares were outstanding for the three months ended March 31, 2014 and March 31, 2013, respectively, and were not included in the computation of diluted earnings per share because the awards’ impact on earnings per share was anti-dilutive.
