We include participating securities (unvested share-based payment awards that contain non-forfeitable rights to dividends or dividend equivalents) in the computation of EPS pursuant to the two-class method. Our participating securities consist solely of unvested restricted stock awards, which have contractual participation rights equivalent to those of stockholders of unrestricted common stock. The two-class method of computing earnings per share is an allocation method that calculates earnings per share for common stock and participating securities. During periods of net loss, no effect is given to the participating securities because they do not share in the losses of the Company.
