The assistant answers from what CHA has actually filed: 3 annual reports filed with the SEC and 6 Form 4 filings from the last year. Every figure in a reply links to the filing it came from, so an answer can be checked rather than believed.
Pressing one answers it here, from CHA's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 CHA insiders have filed, not the latest few.
