Questions to carry forward
- What can machines compare after facts are tagged?
- Which accounting judgments remain unresolved by a shared data format?
Claim disciplineEvidence boundaries
- XBRL tagging does not make unlike accounting facts economically comparable or guarantee error-free data.
- The original phase-in details are not a statement of current filing requirements.
The SEC required covered companies to provide financial statement information in an interactive format using XBRL, with implementation phased by filer group. Tags allow software to locate facts and preserve dimensions and context more reliably than extracting numbers from presentation pages alone.
Machine readability does not eliminate accounting analysis. Extensions, contexts, units, period types, restatements, and underlying policy choices can still make superficially similar facts different. Data engineering and accounting judgment therefore meet in the filing.
