Form 3

What Is Form 3?

Form 3, formally called the Initial Statement of Beneficial Ownership of Securities, is a report that certain corporate insiders must file with the U.S. Securities and Exchange Commission (SEC) under Section 16(a) of the Securities Exchange Act of 1934. It applies to company directors, certain officers, and anyone who owns more than 10% of a class of the company's registered equity securities. The form records the person's starting position in those securities as of the date they became an insider.

The information covers more than common stock. It also includes derivative security holdings, such as stock options, and convertible security holdings, such as convertible bonds or preferred stock that can be turned into common shares. The filer must report securities held directly and indirectly, such as shares held by a spouse or by a trust the insider controls.

How It Works

Form 3 is generally due within 10 days after a person becomes an insider, and it is filed electronically through the SEC's EDGAR system. Once filed, the information is publicly available, so anyone can look it up.

Form 3 is only the starting point for insider reporting. Later changes are reported on Form 4, which is filed shortly after a transaction, and certain other changes are reported on Form 5, which is filed annually. Together, these forms let investors follow insider holdings over time.

Why It Matters to Investors

Insiders have a closer view of their companies than the public does, so regulators watch their trading closely, including under rules against insider trading. Form 3 gives investors a baseline for judging how much stock and related securities insiders hold. Comparing the initial filing with later Form 4 and Form 5 reports shows how those holdings have changed.

A filing describes ownership only. It does not indicate whether an insider expects the stock to rise or fall, and it is not a recommendation to buy or sell. Investors can treat it as one piece of public information among many.
