Potential common shares consist of the shares issuable upon the release of restricted stock units (“RSUs”) and the exercise of stock options and stock appreciation rights (“SARs”). The Company’s unvested RSUs and unexercised SARs are not considered participating securities as they do not have rights to dividends or dividend equivalents prior to release or exercise.

The following table sets forth the number of potential common shares not included in the calculation of diluted earnings per share because their effects were anti-dilutive:
