OpenCorporates

These reports must list "significant" subsidiaries.

We believe it's vital for our society to understand how corporations exercise control over their various parts.

Our OpenCorporates robots attempt to extract this information automatically, but sometimes they get it wrong.

When our robots get it wrong, we need intelligent humans (like you!) to help extract this data. You'll be copying information from SEC filings into a form on OpenCorporates.

Sometimes the data is quite complex - for example, when there are subsidiaries-of-subsidiaries listed. In these cases, just click the button which refers the filing to an expert.

Thanks for helping - by making this data open, you will help journalists, researchers and consumers monitor the structure of these powerful companies.

We ask all our contributors to log in. This is so we can track data quality and make it less likely we'll be spammed. If you login with Twitter or LinkedIn, we promise not to post anything to your account without asking you first.
