text: We measure goodwill as the fair value of the consideration transferred, 
  less the net recognized amount of the identifiable assets acquired and 
  liabilities assumed, all measured at fair value as of the acquisition date. 
  When the excess is negative, a bargain purchase gain is recognized 
  immediately in profit or loss. 
  
  We use estimates and judgment to determine the fair value of assets 
  acquired and liabilities assumed, using the best available information 
  including information from financial markets. This may include 
  discounted cash flow analyses which utilize key assumptions such as 
  discount rates, attrition rates, and terminal growth rates to estimate 
  future earnings. We expense the transaction costs associated with the 
  acquisitions as we incur them. 
  
  See note 7 for information related to business combinations in 2013 
  and 2012. 
  
  **Use of Estimates and Judgments**
  When preparing our 
  statements, management makes 
  judgments, estimates and assumptions that affect how accounting 
  policies are applied and the amounts we report as assets, liabilities, 
  in the assumptions, 
  revenue and expenses. Significant changes 
  including those related to our future business plans and cash flows, 
  could materially change the carrying amounts we record. Actual results 
  could be different from these estimates.
