Net Income per Common Share Net Income per Common Share
Basic net income per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted net income per common share is computed by dividing net income available to common stockholders, plus income attributable to dilutive shares and convertible common units, for the period by the weighted average number of common shares that would have been outstanding assuming the issuance of common shares for all potentially dilutive common shares outstanding during the reporting period.
The following is a reconciliation of the denominator of the basic net income per common share computation to the denominator of the diluted net income per common share computation:
