12. | Net (Loss) Income per Share Attributable to Sterling Common Stockholders
Basic net (loss) income per share attributable to Sterling common stockholders is computed by dividing net (loss) income attributable to Sterling common stockholders by the weighted average number of common shares outstanding during the period. Diluted net (loss) income per common share attributable to Sterling common stockholders is the same as basic net (loss) income per share attributable to Sterling common stockholders but includes dilutive unvested stock and 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 (loss) income attributable to Sterling common stockholders (amounts in thousands, except per share data):
|  | Three Months Ended March 31, |
|  | 2015 |  |  | 2014 |
Numerator: |  |  |  |  |  |
Net (loss) income attributable to Sterling common stockholders |  | $ | (16,992 | ) |  | $ | 205 |
Denominator: |  |  |  |  |  |  |  |
Weighted average common shares outstanding – basic |  |  | 18,902 |  |  |  | 16,668 |
Shares for dilutive unvested stock and stock options |  |  | - |  |  |  | 187 |
Weighted average common shares outstanding and incremental shares assumed repurchased – diluted |  |  | 18,902 |  |  |  | 16,855 |
Basic and diluted (loss) earnings per share attributable to Sterling common stockholders |  | $ | (0.90 | ) |  | $ | 0.01 |
In accordance with the treasury stock method, no shares of unvested common stock and stock options were excluded from the diluted weighted average common shares outstanding for the three months ended March 31, 2015, as the assumed proceeds related to these shares would purchase more shares than the unvested shares outstanding resulting in anti-dilution.
