Notes and known gaps
How these numbers are put together, and what they can't tell you.
- Numbers come from the XBRL data in each period's original 10-K, 10-Q, 20-F or 40-F, or its amendment. They are shown as filed: later filings don't restate earlier periods here.
- Reported is the filing date of the first 8-K with Item 2.02 (results of operations) after the period ended, no later than the 10-Q or 10-K and within 120 days. Companies that release results only in the 10-Q, and foreign companies, which use Form 6-K, have none.
Known gaps
- Foreign companies that file Form 20-F or 40-F have annual statements only: their quarterly results are furnished on Form 6-K, which has no XBRL data.
- EPS and share counts are as reported at the time, not adjusted for later stock splits.
- For ADRs, EPS is per ordinary share, not per ADS (one TSMC ADS is five ordinary shares).
- For banks, revenue may be interest income only, depending on how the bank tags its filings; cost of revenue and gross profit are usually blank.
- Companies with several share classes, such as Berkshire Hathaway, may have no EPS and no cover share count.
- Depreciation and amortization is missing for some companies that report it under their own XBRL tags.
