How the figures were made

Suppliers and customers. Records are grouped by counterparty, and counterparties with more current records come first; disclosures that name no counterparty share one entry. A disclosure more than 5 years old is kept as a record of the past, not evidence of a current relationship, and follows the current records with its fiscal year; a relationship whose recorded end date has passed is marked ended with that date and what it rests on, and follows them too. A product or service, a percentage (the supplier’s share of one product line in the customer’s inputs) and a sole-source mark appear only where the record’s cited source states them for the pair: where a record names no product, its source states none or the description on file has not been tied to the cited source, and records that would read the same are printed once with their count. Where one source’s records about a counterparty cite different documents, each names the site it cites. Alternative suppliers may exist outside this corpus.

Licensed supply-chain database. A licensed supply-chain database records 1 supplier of UMC beyond the public records; matched to Scrutica’s records by name alone, none is named until the match is confirmed. The database’s exact figures are withheld. Stock-price correlations appear only in fixed half-unit bands.

Names and pale marks. The companies named at the foot of each side lead the live record’s ledger: most current records first, ties in the ledger’s own order. What each supplies or buys is read from its latest dated record. A public counterparty is drawn pale when every record it has is a disclosure more than 5 years old or has ended.
