Schedule of calculation of basic and diluted earnings per share

The following is a reconciliation of the calculation of basic and diluted earnings per share. Basic net income per common share is calculated by dividing net income available to common shareholders by the weighted average common shares outstanding during the reporting period. Diluted net income per common share is computed similarly to that of basic net income per common share, except that the denominator is increased to include the number of additional common shares that would have been outstanding if all common shares underlying potentially dilutive stock options were issued or restricted stock would vest during the reporting period utilizing the Treasury stock method.
