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 share is calculated by dividing net income available to shareholders by the weighted average shares outstanding during the reporting period. Diluted net income per share is computed similarly to that of basic net income per share, except that the denominator is increased to include the number of additional shares that would have been outstanding utilizing the Treasury Stock Method if all shares underlying potentially dilutive stock options were issued and all restricted stock, stock warrants or restricted stock units were to vest during the reporting period.
