The Open Database Of The Corporate World

Subsidiaries listed in SEC filings (data)

Prices from £11,560

This dataset comprises subsidiaries extracted from current 10-K and 20-F filings at the SEC. It lists more than 250,000 subsidiaries worldwide, of over 5,000 major companies.

For each relationship we record the parent and child entity, along with the reporting date of the filing, and a source URL. The dataset is updated monthly. Because SEC filings come in many different formats, we are not always able to extract the data automatically; we do cover the majority of the subsidiaries actually listed in filings.

Want to use this data for an open-data project?

Our goal at OpenCorporates is to improve access to and quality and understanding of data about companies, under a licence that encourages reuse. We want you to use our data, for a public purpose, for journalism, for academic research, for other great open data websites and services, and also commercially. If your proposed use of our data means you are able to freely share your results under the terms of our Open Data licence, then we can usually provide you with these products at no cost.
