Earnings Per Share [Abstract]  
Per Share Data

16.  Per Share Data

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding. The dilutive effect of incremental common shares potentially issuable under outstanding options, warrants and restricted shares is included in diluted earnings per share in 2011 utilizing the treasury stock method. The computations of basic and diluted per share data were as follows:

     
  2012   2011   2010
Net (loss) income   $ (16,354 )    $ 3,893     $ (10,951 ) 
Weighted average common shares outstanding – basic     183,572,582       183,023,590       175,698,489  
Effect of dilutive securities:                           
Options to purchase common stock     —       3,616,816       —  
Warrants to purchase common stock     —       2,313,636       —  
Restricted shares     —       59,986       —  
Dilutive potential common shares     —       5,990,438       —  
Weighted average common shares
outstanding – dilutive 		    183,572,582       189,014,028       175,698,489  
Net (loss) income per share:                           
Basic and diluted   $ (0.09 )    $ 0.02     $ (0.06 ) 

During 2012, 2011 and 2010, options, warrants and restricted stock to purchase 54,837,515, 13,337,994 and 30,012,740 common shares, respectively, were not included in the computation of diluted income (loss) per share as the effect would be anti-dilutive.
