20-F / 6-K (Foreign Issuer Filings)
The filings a foreign company listed in the U.S. submits instead of the 10-K and 10-Q — the 20-F annually and the 6-K as events arise, with no quarterly reporting requirement.
In plain terms
A company listed on a U.S. exchange but headquartered outside the U.S. files different documents. It submits a 20-F once a year, and a 6-K in between whenever there is something to report.
The biggest difference is quarterly reporting. U.S. companies must file a 10-Q each quarter, but foreign private issuers have no such obligation. Many report only semi-annually, following their home-country rules.
What it tells you
If a stock's quarterly figures are late or missing altogether, this is usually why. It isn't that the data couldn't be obtained — that company simply isn't subject to quarterly reporting.
A 20-F also contains items not found in U.S. company filings. Risks arising from home-country circumstances, such as the local regulatory environment, exchange rates, or capital controls, may be described separately.
Formula
Foreign Private Issuer → **20-F** (annual) · **6-K** (as needed) Unlike the [10-K and 10-Q](sec-filings) of U.S. companies, there is **no quarterly reporting requirement** Accounting standards may be either US GAAP or **IFRS**
What high or low means
If the accounting standard is IFRS, item names and calculation methods differ from US GAAP. Even a familiar line like operating income can differ in what it includes.
The 20-F filing deadline is four months after the fiscal year ends. That is more time than for the 10-K, so at the same point in time a foreign private issuer's figures may be older.
A company that files only a 20-F does not disclose quarterly results at all. So «no quarterly results visible» does not mean data is missing — it is that company's reporting cycle.
Unlike the 8-K, the 6-K does not sort «what happened» into numbered items. So it is hard to know the content until you open the title.
When placing a company side by side with a US company, check first whether the accounting standards and reporting cycles match, so things do not get out of line.
Some Canadian companies use another form called the 40-F. That is because the US and Canada have a separate arrangement for recognizing each other's filings.
