What Is the 25% Rebuttable Presumption of Control for RIAs?
Direct Answer
Under Investment Advisers Act rules, a person or entity that owns, controls, or holds the power to vote 25% or more of an investment adviser's voting securities is presumed to control that adviser. This is a rebuttable presumption, not a fixed threshold: ownership below 25% can still be found to constitute control based on other facts, and ownership at or above 25% can potentially be rebutted with contrary evidence. Because the presumption affects whether a transaction triggers assignment and consent requirements, ownership structure in an RIA deal is typically reviewed against this standard early in diligence.
The Presumption and Its Statutory Source
Rules under the Investment Advisers Act treat 25% or more ownership, control, or voting power over an adviser's voting securities as a presumption of control for purposes of the assignment and consent rules. The 25% figure gives buyers, sellers, and their counsel a working reference point when a deal team is trying to determine, early in structuring, whether a given ownership stake will be treated as control for regulatory purposes. It is a starting presumption built into the analysis, not a standalone rule that operates on its own.
Why It Is Rebuttable, Not a Bright-Line Trigger
A rebuttable presumption shifts the starting point of the analysis without deciding the outcome. Crossing 25% does not automatically establish control, and staying under 25% does not automatically avoid it. The presumption exists because ownership percentage alone is an imperfect proxy for actual control, so regulators built in room for the facts of a specific transaction, such as governance terms and voting arrangements, to override the raw percentage in either direction.
Facts That Can Rebut or Reinforce the Presumption
Board representation, veto rights over major decisions, the ability to appoint or remove key personnel, and voting agreements among multiple owners can all reinforce a finding of control even at ownership levels below 25%. Conversely, passive minority protections, absence of governance rights, or contractual limits on influence can support rebutting the presumption for a holder above 25%. Deal counsel typically maps these facts against the ownership structure rather than relying on the percentage alone.
How This Affects Deal Structuring
Because the presumption is fact-dependent, deal teams typically evaluate proposed ownership and governance terms against it before finalizing structure, not after. Minority investment rounds, staged buyouts, and rollover equity arrangements can each land on different sides of the presumption depending on how voting rights and governance are allocated, which in turn affects whether the transaction requires the assignment and consent process described elsewhere in this glossary.

Frequently Asked Questions
Does owning less than 25% mean a transaction is not an assignment?
No. The 25% figure is a presumption, not a boundary. An investor holding well under 25% can still be found to control the adviser based on governance rights, board seats, veto powers, or other facts, which would still make the transaction an assignment requiring consent.
Can the presumption be rebutted?
Yes, in either direction. An owner at or above 25% can potentially show they do not exercise actual control, and an owner below 25% can be shown to control the adviser despite the lower stake. The presumption sets a starting point for the analysis, not a final answer.
