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 unvested stock 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 (loss) attributable to Sterling common stockholders (amounts in thousands, except per share data):

In accordance with the treasury stock method, zero and approximately 0.3 million shares of unvested common stock were excluded from the calculation of the diluted weighted average common shares outstanding for the three and nine months ended September 30, 2016, as the Company incurred a loss during the nine month period and the impact of such shares would have been antidilutive. In accordance with the treasury stock method, 0.2 million and 0.4 million shares of unvested common stock were excluded from the diluted weighted average common shares outstanding for the three and nine months ended September 30, 2015, as the assumed proceeds related to these shares would purchase more shares than the unvested shares outstanding resulting in anti-dilution.
