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 and warrants 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 (in thousands, except per share data):

There were 2,800 and 95,107 weighted average options outstanding during the three and six months ended June 30, 2012 and 2011 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 net income (loss) per share attributable to Sterling common stockholders.  In addition, and in accordance with the treasury stock method, 86,544 shares of stock options and restricted stock were excluded from the diluted weighted average common shares outstanding for the six months ended June 30, 2012 as the Company incurred a loss during this period and the impact of such shares would have been antidilutive.
