Private companies are required to file reports with the Securities and Exchange Commission (SEC) if they meet these criteria:

• Companies with more than $10 million in assets whose stock is held by more than 500 owners.
• Companies that have made a public debt offering.

Companies often provide copies of their SEC filings on the Investor Relations pages of their website. The databases listed here give access to all SEC company filings.

Many private companies are required to file statements with their state regulators. Information varies by state from brief company profile to full financial statements.

Large public companies and multinationals often own many private subsidiaries. Subsidiaries are "wholly-owned" when 100% of their stock is owned by the parent companies. Information about these subsidiaries can sometimes be found in the SEC filings of the parent company.

Companies are not required to report the results of divisions or subsidiaries.  They are required to report results of any grouping of products or services that represents 10% or more of total revenues, assets or income. Companies define these groupings and report the results in the 10-K report.
