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:

     
  2011   2010   2009
Net income (loss)   $ 3,893     $ (10,951 )    $ (18,673 ) 
Weighted average common shares outstanding – basic     183,023,590       175,698,489       168,623,375

Common stock options     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 – diluted     189,014,028       175,698,489       168,623,375
