Foreign private issuer. Non-US companies that list ADRs file annual 20-F reports but their officers and directors are exempt from SEC Section 16 — so no Form 4s exist at all (e.g. Spotify, Alibaba, Toyota).
No recent insider activity. Smaller US issuers can go quarters without an insider trade; Form 4 only fires on actual transactions.
