12. | Net Income (Loss) per Share Attributable to Sterling Common Stockholders
Basic net income (loss) per share attributable to Sterling common stockholders is computed by dividing net income (loss) attributable to Sterling common stockholders by the weighted average number of common shares outstanding during the period. Diluted net income (loss) per common share attributable to Sterling common stockholders is the same as basic net income (loss) per share attributable to Sterling common stockholders but includes dilutive stock options using the treasury stock method. The following table reconciles the numerators and denominators of the basic and diluted per common share computations for net income attributable to Sterling common stockholders (amounts in thousands, except per share data):
|  | Three Months Ended March 31, |
|  |  | 2013 |  |  |  | 2012 |
Numerator: |  |  |  |  |  |  |  |
Net loss attributable to Sterling common stockholders |  | $ | (4,580 | ) |  | $ | (7,500 | )
Revaluation of noncontrolling interest obligations reflected in retained earnings, net of tax |  |  | (1,854 | ) |  |  | 301 |
|  | $ | (6,434 | ) |  | $ | (7,199 | )
Denominator: |  |  |  |  |  |  |  |
Weighted average common shares outstanding — basic |  |  | 16,598 |  |  |  | 16,322 |
Shares for dilutive stock options and warrants |  |  | -- |  |  |  | -- |
Weighted average common shares outstanding and assumed conversions— diluted |  |  | 16,598 |  |  |  | 16,322 |
Basic loss per share attributable to Sterling common stockholders |  | $ | (0.39 | ) |  | $ | (0.44 | )
Diluted loss per share attributable to Sterling common stockholders |  | $ | (0.39 | ) |  | $ | (0.44 | )
There were 2,800 weighted average options outstanding during the three months ended March 31, 2012 and none in 2013 which were considered antidilutive as the option exercise price exceeded the average share market price and were therefore excluded from the denominator used for computing diluted loss per share attributable to Sterling common stockholders. In addition, and in accordance with the treasury stock method, 135,879 and 59,444 shares of stock options and restricted stock were excluded from the diluted weighted average common shares outstanding for the three months ended March 31, 2013 and 2012, respectively, as the Company incurred a loss during these periods and the impact of such shares would have been antidilutive.
