Data quality and traceability

How quality is documented

Every field in the dataset carries provenance metadata. Reported values, calculated fields, documented gaps, and known limitations are visible throughout — not hidden behind a single confidence score.

Quality principles

Source documents

Annual reports and company disclosures form the primary evidence base for all annual and interim data rows.

Reported vs calculated

Reported fields from company filings are kept separate from calculated fields like margins, FCF, and valuation ratios.

Missing values are not estimated

When a value is unavailable, it is left blank and documented. The dataset does not fill gaps with estimates or interpolated values.

Currency separation

Reporting and market currencies are tracked separately so accounting and market fields remain traceable.

Interim reporting varies

Q1 and H1 coverage differs by company. Some companies publish only sales updates for Q1, not full P&L releases.

Valuation ratios are conditional

Valuation ratios (P/E, EV/EBITDA) appear only when the required market data, currency context, and accounting inputs are all available. They are left blank otherwise.

Source tracking

Source URLs and status fields connect each annual row back to company disclosures or archived official reports.

Field provenance

Provenance metadata tracks whether each field is reported, calculated, verified, or carries documented limitations.

Examples of documented limitations

These are real examples from the preview dataset. They illustrate the kinds of issues the quality layer surfaces — not all rows are clean.

Negative cash values

Some companies report negative cash due to overdraft netting or cash pooling in their annual reports. These values are used as-is and flagged, not corrected.

Calculated free cash flow

When a company does not report FCF directly, it is calculated as operating cash flow minus capital expenditure. These rows are marked as calculated, not reported.

Missing capex data

Some fiscal years lack a separately reported capital expenditure figure. When capex is unavailable, FCF cannot be calculated and both fields are left blank.

Per-share comparability

Pre-stock-split per-share figures may not be directly comparable across years. These rows carry a documented note about the split event.

Quality snapshot by company

Status reflects dataset completeness and documentation quality — not a judgment on the underlying company.

Quality statuses describe dataset completeness and traceability, not the attractiveness of a security. "Verified" means the row has been checked against sources — it does not mean every field is present.
