Questions to ask before you begin your research:
Private companies do not have to disclose any information to the public. They are difficult if not impossible to research.
Public companies are easiest to research. They are regulated by the government (in the U.S., it's the SEC), sell shares to the general public, and must publicly report company and financial information.
Subsidiary companies will not have their own annual reports, and you may not find information on them in the resources listed on this page. You'll need to determine who the parent company is and research the parent company. Journal articles will be a major source for information on subsidiaries.
International companies also won't be included in some of the databases, such as NetAdvantage. Check Mergent or Business Source Complete for international company information.
This depends upon your need. Best place, if you're unsure--is under the Company Profiles tab. Company profile data provides you with an in-depth overview of the company, the industry, its finances.
