| 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:  Net (Loss) Income(Numerator)  Weighted AverageCommon Shares(Denominator)  Per ShareAmount 2012:      Basic and diluted $(35,431)  34,754  $(1.02)2011:            Basic $10,381   33,375  $0.31   Dilutive effect of stock options  -   66       Dilutive effect of restricted stock  -   53     Diluted $10,381   33,494  $0.31 2010:            Basic and diluted $(69,725)  32,590  $(2.14) |

Tabular disclosure of securities (including those issuable pursuant to contingent stock agreements) that could potentially dilute basic earnings per share (EPS) in the future that were not included in the computation of diluted EPS because to do so would increase EPS amounts or decrease loss per share amounts for the period presented, by antidilutive securities.
