What this compares

Which of the topics we track appear in each company's SEC filings, and how often. A topic appearing for one company and not the other means one wrote the phrase down and the other did not, in the filings we hold. It does not mean one faces a risk the other does not, and it is not a comparison of how well either manages anything.

Counts reflect the filings we have collected, which is a growing subset rather than a company's complete history.
