The assistant answers from what GGB has actually filed: 11 annual reports filed with the SEC, 26 Form 4 filings from the last year and 1 fund that holds it. 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 GGB's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 GGB insiders have filed, not the latest few.
Ten seconds, no card, and nothing to cancel.
