Subsidiaries

subsidiaries is a first-class data block in the Topograph data model. Where shareholders describe who owns the queried company (the upstream edge), subsidiaries describe what the queried company owns (the downstream edge). A subsidiary record is always a company. It carries the equity stake the queried company holds in it, plus optional details such as voting rights, nominal capital held, and acquisition or end dates. Classification (controlled, associated, minority investment) is left to the caller. Use the exact percentage or disclosed interval when available.

Supported Countries

subsidiaries is a separate data block from company in every country below, and it is available in verification mode only. Where it is AI-extracted from a filed financial statement, availability follows the company’s filing obligation rather than our coverage: a company that filed no accounts returns an empty list, and small or micro-entity filers are usually exempt from the disclosure that carries the data.

A country not listed here does not serve subsidiaries: requesting it returns datapoint_not_supported, not an empty list. Requesting it in onboarding mode for a country that does serve it returns fast_source_unavailable, because the data comes from a filing that has to be fetched and parsed. More countries follow the same shape and will be added as their registers expose participation data. Check Coverage and pricing for the live list.

Field reference

Field	Type	Notes
`company`	object	The owned company (`legalName`, `countryCode`, `id`, `identifiers`).
`sharePercentage`	number	Exact direct equity stake (0–100). Omitted when only a range is disclosed.
`sharePercentageRange`	object	Disclosed direct equity interval: `lower`, `upper` (0–100), and optional `lowerInclusive` / `upperInclusive` flags.
`totalSharePercentage`	number	Direct + indirect stake when the source can compute it.
`votingRightsPercentage`	number	Voting power, when it differs from equity.
`numberOfShares`	number	Absolute share or quota count.
`nominalCapitalHeld`	MonetaryAmount	Total nominal value of the equity held.
`paidInAmount`	MonetaryAmount	Total amount actually paid for the equity.
`acquisitionDate`	ISO 8601 date	When the participation was acquired.
`endDate`	ISO 8601 date	When the participation ended (sale, dissolution). Omitted for current participations.

Ownership intervals and missing percentages

When the source discloses an interval, sharePercentageRange preserves it and sharePercentage is omitted. For example, “more than 25% and at most 50%” is returned as:

{
  "company": { "legalName": "Example Ltd", "countryCode": "GB" },
  "sharePercentageRange": {
    "lower": 25,
    "upper": 50,
    "lowerInclusive": false,
    "upperInclusive": true
  }
}

lowerInclusive and upperInclusive indicate whether the corresponding endpoint is included. They are omitted when the source does not specify inclusivity. A one-sided threshold uses the percentage limits for the other bound: “more than 75%” has a lower bound of 75 (excluded) and an upper bound of 100 (included). Exact values use only sharePercentage, including an explicitly disclosed 0% or 100%. When neither an exact percentage nor an interval is disclosed, both fields are omitted and the company can still appear in the list. Treat missing percentages as unknown, never as zero. No midpoint or endpoint estimate is supplied for an interval.

Best practices

Derive control from sharePercentage

Topograph does not flag participations as “controlled” or “associated”. Apply your own threshold (commonly 50% for control, 20% for significant influence) so the rule stays explicit in your code. For a range, classify only when the whole interval satisfies your rule. If it crosses your threshold or endpoint inclusivity is needed but unspecified, the percentage alone cannot establish the classification.

Combine with shareholders for a full picture

Request shareholders and subsidiaries together to see both ends of the ownership graph for the queried company.

Use endDate to filter historical participations

Records with a non-empty endDate describe past holdings. Filter them out unless you need historical context.
