12. | Net Loss per Share Attributable to Sterling Common Stockholders
Basic net loss per share attributable to Sterling common stockholders is computed by dividing net loss attributable to Sterling common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share attributable to Sterling common stockholders is the same as basic net loss per share attributable to Sterling common stockholders but includes dilutive unvested common 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 the net loss attributable to Sterling common stockholders (amounts in thousands, except per share data):
