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 assumes the exercise of 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 net loss attributable to Sterling common stockholders for 2015, 2014 and 2013 (amounts in thousands, except per share data):

The Company had no options outstanding but considered antidilutive due to the option exercise price exceeding the average share market price at December 31, 2015, 2014 and 2013, respectively. In addition, approximately 0.4 million, 0.2 million and 0.2 million shares of unvested stock and stock options were excluded from the diluted weighted average common shares outstanding in 2015, 2014 and 2013, respectively, as the Company incurred a loss in these years and the impact of such shares would have been antidilutive.
