Revenue is very small next to this company's costs or profit, so its margins here are extreme figures (beyond ±100%). They are what the reported numbers give, but they say little about how the business earns.

How these figures are worked out
- Last close: the closing price on the date shown. The page follows the market's close; it doesn't show prices during the session. A price older than the market's latest close, or a last trade that isn't a close, is labelled as the last price, with the session it is from.
- 1-year range: the lowest and highest prices traded during the sessions of the last year (intraday), so they can lie outside the closing prices.
- Market cap: the last close times the shares in issue. It is n/a when it doesn't agree with the company's own reported figures (for example a depositary share counted as an ordinary share).
- P/E: the last close divided by earnings per share over the last four reported quarters, the profit that belongs to the company's shareholders per share, as the company reports it. So P/E can differ from market cap divided by the net profit shown (a different share count, or the profit before minority interests; where they differ by more than 10%, a note under the figures gives both). A company that reports only once a year has its latest year's earnings, and the P/E names that year; when that year ended more than about 15 months before the close, P/E is n/a. A loss has no P/E. Above 1,000 it is n/a.
- EBITDA margin: operating profit before depreciation, interest and tax (and before other income), as a share of revenue in the latest reported year, the table's last column.
- Net margin: net profit as a share of revenue in the latest reported period. Return on equity, the margins and debt to equity each use inputs from that one year; if one input is missing for it, the figure is n/a. When that year ended more than about 15 months before the close, they are n/a too.
- Dividend yield: every dividend per share with an ex-date in the 12 months to the last close, special dividends included, as a share of that close. n/a when the company's dividends couldn't be read.
- n/m: not meaningful. A margin or return beyond ±1,000% comes from revenue or equity near zero, so it is not shown as a number.
