10.   Net Income per Share Attributable to Sterling Common Stockholders

Basic net income per share attributable to Sterling common stockholders is computed by dividing net income attributable to Sterling common stockholders by the weighted average number of common shares outstanding during the period.  Diluted net income per common share attributable to Sterling common stockholders is the same as basic net income per share attributable to Sterling common stockholders but includes dilutive stock options and warrants using the treasury stock method.  Diluted earnings per common share attributable to Sterling common stockholders excludes stock options which were outstanding during the three and six months ended June 30, 2011 to purchase 95,107 and 95,107 shares, respectively, and stock options which were outstanding during the three and six months ended June 30, 2010 to purchase 119,407 and 95,307 shares, respectively, as such impact was anti-dilutive.
