Additional Details
Exhibit 21 is an unstructured text or PDF attachment to the main SEC 10-K filing that is used to describe the subsidiaries owned by the filing company. It may or may not provide the percentage of the subsidiary that is owned by the filing company, or the location of the subsidiary.
Columns
Unique portion of the filename associated with the SEC 10-K filing in the EDGAR database. The full source URL can be reconstructed by prepending https://www.sec.gov/Archives/edgar/data/ and adding the .txt file type extension.
Name of subsidiary company.
Location of subsidiary company. This is the full US state name or country name and occasionally a two digit code that was not mapped to a full name during cleaning.
PUDL-assigned ID for subsidiaries found in SEC 10-K Exhibit 21. The ID is created by concatenating the CIK of the company whose filing the subsidiary was found in, the subsidiary company's name, and location of incorporation. It is not guaranteed to be stable across different releases of PUDL and so should never be hard-coded in analyses.
