How to report an error
Email Contact email with the subject “Correction Request.” Include the page or publication, the statement in question, the source supporting your concern, and the correction you believe is appropriate.
How we review reports
We compare the challenged statement with primary sources, reliable secondary sources, calculation records, and the context in which the statement appeared. We distinguish factual errors, calculation errors, stale information, presentation problems, and reasonable differences in analysis or opinion.
Types of corrections
- Material errors: inaccuracies that could change the meaning, risk assessment, historical record, or reader understanding.
- General errors: incorrect names, figures, dates, labels, links, or source descriptions that do not change the central conclusion.
- Presentation errors: formatting or typographical issues that affect clarity without changing the underlying fact.
- Interpretive disagreements: differences in analysis that are not factual errors but may justify clarification or additional sourcing.
Historical record corrections
A correction involving a displayed historical result should identify the security, record date, measurement basis, start and end values, calculation, and source. If a displayed percentage or label is changed, the related archive should preserve the reason for the change and the corrected value.
How corrections are shown
Material corrections should be explained where readers are likely to encounter the affected content. General or presentation corrections may be made directly when a separate notice would add little value. A correction should not conceal the original issue or create a misleading impression about when the underlying information was available.
Differences of judgment
A disagreement with an analytical conclusion is not automatically an error. We may add context, clarify assumptions, or identify competing interpretations when doing so improves the publication.
Review timing
The time needed to review a report depends on source availability, complexity, potential impact, and whether third-party confirmation is required. We do not promise a fixed response or correction period.
