How a share count is chosen, and when we refuse one

Every share count on this site is a figure a company filed with the SEC. Two places turn one into something else, and they follow two different rules, both stated here.

1. This page: a chain, first usable count wins

1. dei:EntityCommonStockSharesOutstanding, the cover-page count. A point-in-time count, used whenever its as-of date is within 200 days.
2. us-gaap:CommonStockSharesOutstanding, the balance-sheet count, also point in time, when the cover page is older than that.
3. us-gaap:WeightedAverageNumberOfSharesOutstandingBasic, an average over the reporting period, used only when no point-in-time count is current, and labelled as an average.
4. The cover page of the newest annual or quarterly report, read directly, when the concept data holds nothing usable. Where it lists more than one share class, the classes are summed as filed and each is shown.

A value 100 times or more away from the median of its own concept’s history is a filer’s scale error and is rejected. Every candidate that lost is listed with its reason. The low-float read itself is withheld once the count is more than 130 days old, a quarter plus filing lag: the count is then shown as filed, without a verdict.

2. The company workspace: market cap

Market cap is the last end-of-day close times one count, picked from the company’s SEC companyfacts in this order, each only when it is current: no more than about 15 months older than the company’s newest annual or quarterly report in the same data.

1. dei:EntityCommonStockSharesOutstanding, the cover-page total.
2. us-gaap:CommonStockSharesOutstanding, the balance-sheet total.
3. us-gaap:WeightedAverageNumberOfDilutedSharesOutstanding for the newest quarter, an average over that quarter rather than a count at one date, and named that way in the tile and its source token.
4. None: the figure is withheld with the reason, for example “shares reported by class only”. A company with several share classes can tag one cover-page count per class, which companyfacts leaves out, and some have filed no single total since 2010.

The tile’s source token shows the close and its date, the count, its concept, its as-of date or quarter and the filing it came from. The figure is also withheld when the count is more than 200 days older than the close.

3. Foreign issuers and ADRs

A company filing on a 20-F, 40-F or 6-K reports ordinary shares, while what trades here is often an ADS worth several of them. The ratio is not in XBRL, so it is read from the company’s own filing prose, checked against the filed count, and divided through: ordinary shares divided by ordinary shares per ADS gives the ADS count. When no ratio can be read, or the one read fails that check, both surfaces abstain rather than multiply a price per ADS by a count of ordinary shares.

4. More than one share class

Where the cover page lists classes separately, this page sums them as filed and shows each class. Neither surface converts one class into another: conversion ratios live in filing prose, and a site printing an as-converted total will show a different number. A company that tags its classes only separately has no single cover-page total in the concept data, so the workspace falls back to the balance-sheet count, or withholds the cap when there is none.
