| Possible exact normalized-name match | not_found_in_checked_records | 0 | Requires review of the official record; a name match does not identify an entity. |
| Subsidiary relationship | not_covered | 0 | Ownership and subsidiary relationships are not inferred from names. |
| Ownership / control relationship | not_covered | 0 | Control is not inferred from a sanctions-list name or a ticker. |
| Management relationship | not_covered | 0 | Management exposure requires a separately sourced relationship record. |
