How this figure is calculated
Shares reported in SEC insider filings (Forms 3, 4 and 5), at the latest holding each filing reports, valued at the latest price disclosed in those filings, or at the latest closing price where no recent trade price was filed. Share classes that convert one for one into listed shares are counted at the listed price. Holdings that the filings say belong to investment funds managed by the person, and unvested performance awards, are left out; shares reported jointly by several family members are counted once; where insider filings count the same shares more than once, the figure is capped at the holding in the company's latest proxy statement. Where a holding is not covered by US insider filings, the latest annual report (Form 20-F), proxy statement or ownership filing (Schedule 13D) is used instead, as linked in the table. Private companies, cash, property and holdings listed outside the United States are not included, so this is a minimum, not total wealth. The household comparison uses $192,700, the median US household wealth in the Federal Reserve Survey of Consumer Finances (2022, the latest published).
