Control Securities

Control Securities are securities held by an affiliate of the issuer, such as a person who directly or indirectly controls, is controlled by, or is under common control with the issuer.

Updated 2026-09-02 · Foundation

How it works

Control Securities are defined by the holder’s relationship to the issuer rather than solely by how the securities were acquired. An affiliate can therefore hold control securities that were purchased in the public market and are not restricted securities. When an affiliate resells securities in reliance on Rule 144, the resale can be subject to current public information, volume, manner-of-sale and Form 144 conditions even if the shares are otherwise unrestricted.

Control status comes from affiliate status

Rule 144 defines an affiliate through direct or indirect control, common control or control by the issuer.

Public-market acquisition does not eliminate control status

An affiliate’s market-purchased shares can remain control securities even though they are not restricted securities.

Affiliate resales face additional conditions

Rule 144 can impose volume limits, manner-of-sale requirements, current public information and Form 144 obligations.

Former affiliates remain relevant for a period

Rule 144 looks to whether the seller was an affiliate during the 90 days immediately before the sale for specified conditions.

Worked example: unrestricted but controlled

An executive buys 50,000 exchange-traded shares through a broker. No Rule 144 holding period arises from that market purchase, but affiliate-sale conditions can still restrict the resale.

Why control status affects liquidity

Large insiders can own freely issued securities yet still face a narrower path to public resale than ordinary non-affiliate investors.

Common mistakes

Using Control Securities as a synonym for Restricted Securities; assuming public-market shares are outside Rule 144 for affiliates; treating job title alone as conclusive control; and ignoring recent-affiliate status.

Example

A company director buys shares on the open market. The shares are not restricted merely because the director bought them, but the director can be an affiliate, making the shares Control Securities for Rule 144 resale analysis.

Professional note

Keep the two labels separate: restricted describes the acquisition path; control describes the seller’s affiliate relationship. A security can be restricted, control, both or neither.
