text: **Capital Intensity**
  intensity allows us to compare the level of our additions to 
  Capital 
  property, plant and equipment to that of other companies within the 
  same industry. We calculate it by dividing additions to property, plant 
  and equipment by operating revenue. For Wireless, capital intensity is 
  calculated using total network revenue. We use it to evaluate the 
  performance of our assets and when making decisions about the capital 
  expenditures. We believe that certain investors and analysts use capital 
  intensity to measure the performance of asset purchases and 
  construction in relation to revenue. 
  
  **Return on Assets**
  We use return on assets to measure our efficiency in using our assets to 
  generate net income. We calculate return on assets by dividing net 
  income for the year by total assets as at year end.
