The answer, from the board
STALE states age, not lateness: the newest report ReserveBeat holds for this token is older than the cadence expected for it, which can happen while the next report is not yet due.

An empty cell means ReserveBeat holds no value for it. Empty is never filled with a zero, an estimate, or a figure carried over from another row.
The report carries its accounting firm's signature as an image rather than as text, so its text layer holds no firm name to extract and no firm is stated here. A firm name never enters the board from outside the document it came from, even where the firm is a matter of public record.
A firm name enters the board only from the document's own text, even where the firm is a matter of public record, so an image-only signature leaves the cell unnamed with the reason beside it. These are attestation reports on reserves at a date; they are not audits of Circle's financial statements.

Questions
Common questions
Where do the answers on these pages come from?
Each page reads ReserveBeat's own board when you load it. Figures published by issuers pass through exactly as they appear in the attestation reports ReserveBeat parsed; anything ReserveBeat works out itself is labelled as computed and the calculation is written down.
Why is an answer sometimes empty?
Because ReserveBeat holds nothing for it. An empty cell is never filled with a zero, an estimate, or a figure carried over from somewhere else, and a whole answer is withheld rather than shown stale while the board is under review.
Do these pages define the terms they use?
No. Definitions live in the learn section and are written once. These pages answer questions whose answer is a figure or a state read from the board, and they link to the learn section for the vocabulary.
How often do the answers change?
Whenever the underlying board changes. Nothing on these pages is cached as text, so a new attestation report or a correction shows up on the next page load without anyone rewriting the page.
