Net Income (Loss) Per Share [Abstract]

Calculation of net loss per share, basic and diluted

Our basic net (loss) income per share amounts have been computed by dividing net (loss) income by the weighted-average number of common shares outstanding during the period. For 2012 and 2010, we reported net losses and, therefore, potential common shares were not included since such inclusion would have been anti-dilutive. For 2011, we reported net income, and the computation of diluted earnings per share is based upon the weighted-average number of our common shares and dilutive effect, determined using the treasury stock method, of potential common shares outstanding. As of December 31, 2012, 2011 and 2010, our 28, 98 and 341, respectively, shares of unvested restricted stock outstanding have non-forfeitable rights to dividends. The allocation of 2012 and 2010 net losses and the 2011 net income to these participating securities pursuant to the two-class method is not material to both basic and diluted earnings per share. The calculations of net loss per share, basic and diluted, are as follows:
