Notes on these figures

  • The share price was recently adjusted for a split or a spin-off that the company's last filing does not include yet. Market value, P/E, yields and the other figures measured against the price would mix the new shares with the old figures, so we leave them out until the next filing.
  • The reported profit is far larger than a business usually earns on its market value, which usually means one-off or accounting gains. We leave out the P/E and the earnings yield.
  • Profit over the last twelve months is well above what the business itself earned, because it includes large gains outside the business, such as on investments or from selling a business. The P/E is lower than the business alone would give.
