How to read a proof
- Accession and form identify the filing; the SEC link opens the primary document.
- Tag, dimensions and decimals identify the fact within that filing.
- The knowledge interval says when this value became known and, if restated, when it stopped being current.
- Derived values list every as-reported fact in the chain.
