The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands except per share amounts):

Numerator:            
Net income (loss) $1,830  $(971) $2,413  $(3,174)
Denominator:                
Weighted average common shares:                
Common shares outstanding  41,734   40,954   41,579   40,862 
Less:   Unrestricted stock  (11)  (21)  (11)  (21)
Denominator for basic calculation  41,723   40,933   41,568   40,841 
Weighted average effects of potentially dilutive common stock:                
Stock options  2,037      1,800    
Unvested restricted stock  17      17    
Restricted stock units  222      269    
Warrants            
Denominator for diluted calculation  43,999   40,933   43,654   40,841 
                 
Net income (loss) per share:                
Basic $0.04  $(0.02) $0.06  $(0.08)
Diluted $0.04  $(0.02) $0.06  $(0.08)
 
Because the Company had a net loss for the three months and six months ended June 30, 2017, the number of diluted shares is equal to the number of basic shares. Outstanding options and warrants to purchase common stock, restricted stock and restricted stock units would have had an anti-dilutive effect on diluted per share amounts.
 
The following table sets forth (in thousands) the weighted average number of options and warrants to purchase shares of common stock, restricted stock, and restricted stock units with either exercise prices or unrecognized compensation cost per share greater than the average market price per share of the Company’s common stock, which were not included in the calculation of diluted per share amounts because the effects would be anti-dilutive.
