Additional Details
This table is extracted from the same SEC 10-K filing header information as core_sec10k__quarterly_company_information. Each filing reports the full history of name change associated with a company up to the date of that filing. Because individual companies may appear in multiple filings in the same year, and the same historical name changes will be reported in multiple years, the raw input data contains many duplicate entries, which are deduplicated to create this table. The original name change data only contains the former name and the date of the change.
Roughly 2% of all records describe multiple name changes happening on the same date (they are duplicates on the basis of central_index_key and name_change_date). This may be due to company name reporting inconsistencies or reporting errors in which the old and new company names have been swapped.
Columns
Identifier of the company in SEC database.
Date of last name change of the company.
Name of company prior to name change.
Name of the reporting company.
