How it scores

Five questions, each answered by the measures under it. Every figure is the company's own; the bar beside it is where that figure sits among the companies read here — the top fifth, the bottom fifth, or somewhere between. Not among all listed companies, and for a valuation multiple the low end is the good end.

A measure absent from a block could not be computed from this company's filings. It is left out rather than scored as though it were bad, and the dimension is averaged over what remains. A score is measured against a fixed scale this model states; the bar is measured against the other companies, so the two can disagree — and where they do, that disagreement is the more interesting figure.
