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

From SEC Form 4 filings, filed by officers, directors and 10%-owners within two business days of a transaction. “Indirect” holdings (a trust, an LLC, a family member) are included and not distinguished from direct ones in this table.
Past transactions say nothing about future ones, and none of this is investment advice.
