Library Databases for Company Research
Public vs Private Company
Public Company (also called a Publicly Traded Company)
- Traded on the exchanges (by general public shareholders)
- Required to provide ongoing detailed information in filings made with the Securities & Exchange Commission
- Owned by a closed group
- Not required to release information and can be more challenging to research
- Can range from small businesses to large well-known companies (Hallmark Cards and Mars Candy, for example).
Affiliated with Another Company?
- Linked or related to larger firms
- Several are household names but are difficult to research until one establishes its relationship to the larger company (e.g., American Broadcasting Corp. (ABC) is owned by Disney)
