PFIC-screened (low estimated risk)
Operating company. Estimated passive assets about 11% of total assets at market value (test: 50%) (ESEF, 2025-12-31): well below the thresholds. The test is run by the company each year.
Checked 2026-11-15Xpat's reading · Xpat's reading of PFIC screen for individual stocks: Xpat screens by type of company: operating businesses pass, funds, investment trusts and cash-rich holding companies are excluded. The test is annual and only the company can confirm it, so a stock is PFIC-screened, not certified. Banks and insurers pass only through the active banking or insurance exception, so they are shown as screened with that caveat. Where a company has published a statement, the stock records its year and source. · Xpat's reading of PFIC check from company statements and financial statements: Passive assets are estimated as cash plus financial investments (Xpat counts all cash as passive, the long-standing IRS position). Total assets are taken at market value (market capitalisation at the balance-sheet date plus liabilities), the basis a publicly traded company may use, when the share count and price are known; otherwise at book value, which errs high. A company statement is read from its own clause, and a present-tense statement in the annual report for a year counts for that year. Passive income is estimated as finance income over revenue plus finance income. At or above a legal threshold the stock is excluded; from 60% of a threshold it is flagged as elevated. A company statement that it was not a PFIC, for a year at most two years before the tax year, outweighs the estimate; a statement that it was one excludes the stock. Banks and insurers are not estimated: they rely on the active banking and insurance exceptions. · 26 U.S.C. §1297 — passive foreign investment company (official) · 26 CFR §1.1297-1 — definition of a PFIC (income and asset tests) (official) · 26 CFR §1.1297-4 — qualifying insurance corporation (official)

What it means for a U.S. citizen or green-card holder
No PFIC filing for this holding while it stays a non-PFIC: dividends are reported like any foreign dividend (with a foreign tax credit) and gains as capital gains. Foreign accounts that hold it still count for FBAR and Form 8938.
Company type: Operating company. Evidence gathered 2026-11-15. Educational tool, not tax advice: PFIC status is decided each year on figures only the company has.
