How employee counts are measured
This leaderboard ranks companies by the employee count disclosed in their most recent annual report — the 10-K for U.S. filers, or the 20-F / 40-F for foreign issuers. The figure counts full-time equivalent employees as of the fiscal year-end, so it is a point-in-time snapshot of workforce size, not a flow accumulated over the year, and it refreshes once a year when the annual filing lands.
Coverage is limited to companies whose annual filings report a headcount, so some issuers are absent. To compare corporate size by money rather than people, see the revenue ranking; to chart one company's hiring trend and revenue generated per employee, open its per-company employee count.
