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. Holdings that the filings say belong to investment funds managed by the person are left out, and shares reported jointly by several family members are counted once. 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).
