text: ADDITIONAL GAAP MEASURES 
  
  We include operating income as an additional GAAP measure in our consolidated statements of income because we believe it is a representative of 
  our normal course operating activities, provides relevant information that can be used to assess our consolidated performance, and is meaningful to 
  investors. We calculate it by taking revenue and deducting operating expenses, including restructuring, acquisition and other expenses, and 
  depreciation and amortization as shown in our consolidated statements of income.
