text: **Dividend Payout Ratios**
  We calculate the dividend payout ratio by dividing dividends declared 
  for the year by net income for the year. We use dividends as a 
  percentage of pre-tax free cash flow to conduct analysis and assist with 
  determining the dividends we should pay. We calculate dividends as a 
  percentage of pre-tax cash flow as dividends declared for the year 
  divided by pre-tax free cash flow for the year. 
  
  **Adjusted Net Debt to Adjusted Operating Profit**
  We use adjusted net debt to conduct valuation-related analysis and 
  make capital structure related decisions and calculate it as adjusted net 
  debt divided by adjusted operating profit.
