| Net Loss Per Share                | 3.  Net (Loss) Income Per ShareOur 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. As of September 30, 2012 and 2011, the 28 and 101 shares, respectively, of unvested restricted stock outstanding have non-forfeitable rights to dividends. The allocation of net loss and net income, in the respective periods, to these participating securities pursuant to the two-class method is not material to both basic and diluted earnings per share. For the three and nine months ended September 30, 2012 and for the three months ended September 30, 2011, we reported net losses and, therefore, potential common shares were not included in the computation of diluted net loss per share since such inclusion would have been anti-dilutive. For the nine months ended September 30, 2011, we reported net income, and the computation of diluted earnings per share is based upon the weighted-average number of common shares and dilutive effect, determined using the treasury stock method, of potential common shares outstanding. The calculations of net (loss) income per share, basic and diluted, are as follows:  Net (Loss) Income(Numerator)  Weighted AverageCommon Shares(Denominator)  Per ShareAmount Three months ended September 30, 2012      Basic and diluted $(11,301)  33,848  $(0.33)Nine months ended September 30, 2012            Basic and diluted $(35,107)  33,803  $(1.04)Three months ended September 30, 2011            Basic and diluted $(11,432)  33,710  $(0.34)Nine months ended September 30, 2011            Basic $21,127   33,501  $0.63 Dilutive effect of stock options  -   142     Dilutive effect of restricted stock  -   21     Diluted $  21,127   33,664  $0.63 For the three and nine months ended September 30, 2012 and 2011, anti-dilutive common shares excluded from diluted per share amounts consist of the following: Three Months Ended September 30,  2012  2011  WeightedAverageNumber  WeightedAverageExercise Price  WeightedAverageNumber  WeightedAverageExercise PriceOptions  6,035  $12.22   6,186  $12.65Restricted stock  33       9    Total  6,068       6,195     Nine Months Ended September 30, 20122011 WeightedAverageNumberWeightedAverageExercise PriceWeightedAverageNumberWeightedAverageExercise PriceOptions6,019$12.314,126$15.78Restricted stock 68 -Total 6,087 4,126 |
