What Is a Disclosure?
In finance, a disclosure is the act of making information publicly available so that investors and other parties can evaluate a company, fund, or financial product. The term most often refers to information a company must reveal, such as its financial results, risks, executive pay, and significant events. It can also mean a document that contains such information, or a notice that a seller or adviser must give about fees, risks, or conflict of interest.
Why Disclosure Matters
Investors make decisions based on the information available to them. If some people know important facts that others do not, prices can become distorted and trust in markets can suffer. Mandatory disclosure rules aim to reduce this imbalance by requiring that material information be shared with everyone at roughly the same time. Material information generally means facts a reasonable investor would consider important to a decision. Rules against insider trading work alongside disclosure requirements toward the same goal of fair access to information.
Common Types of Disclosure
- Periodic reports, such as the annual report and quarterly filings
- Current reports on significant events, such as major acquisitions, leadership changes, or lawsuits
- The prospectus, which describes a new security offered for sale
- Fee and conflict-of-interest disclosures from advisers and funds
- Risk disclosures that explain what could go wrong
In the United States, public companies file many of these documents with the Securities and Exchange Commission, where they are available to the public, often through the SEC's EDGAR database.
Limits of Disclosure
Disclosure is only as useful as the information it provides. Documents can be long, dense, and written in technical language, which makes them hard for many individual investors to digest. Companies also have some discretion over how they present results, so reading the footnote sections of a filing and comparing documents over time can add context. Disclosure does not guarantee that an investment will perform well, and it does not prevent losses. Its purpose is to make information available, not to judge whether an investment is wise.
