The assistant answers from what OMC has actually filed: 19 annual reports filed with the SEC, 71 Form 4 filings from the last year, 13F positions from the 2 tracked investors who hold it and 6 funds that hold 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 OMC's filings and figures. One a day without an account; a free account has its own, and no card.
See every Form 4 OMC insiders have filed, not the latest few.
Ten seconds, no card, and nothing to cancel.
