The assistant answers from what PRQR has actually filed: 11 annual reports filed with the SEC and 5 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 PRQR's filings and figures. One a day without an account; a free account has its own, and no card.
