The Company calculates basic and diluted net income per common share in accordance with accounting guidance which requires earnings per share to be calculated pursuant to the two-class method for unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents (whether paid or unpaid).

Basic net income per share is calculated by dividing net income for the period by the weighted-average common shares outstanding for the period. Diluted net income per share includes the effect of dilutive instruments, such as stock options and restricted stock, and uses the average share price for the period in determining the number of shares that are to be added to the weighted-average number of shares outstanding.
