Note 12. Per Common Share Amounts

We calculate basic earnings per common share by dividing net income by the weighted average number of common shares outstanding during the period. We calculate diluted earnings per common share by using the more dilutive of the two class method or the treasury stock method. Unvested share awards and other potentially dilutive common shares, and the related impact on earnings, are considered when calculating diluted earnings per share. The following table provides a reconciliation of the weighted average number of common shares used in the calculation of basic and diluted earnings per share (in thousands):
