The assistant answers from what JKS has actually filed: 17 annual reports filed with the SEC, 10 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.
Press one and the answer appears right here on the page, from JKS's filings and figures. One a day without an account; a free account has its own, and no card.
