Securities Act § 15 — Controlling Person Liability (15 U.S.C. § 77o)

Overview

Section 15 extends liability under the Securities Act to persons who control a primary violator of Securities Act § 11 — Civil Liability (15 U.S.C. § 77k) or Securities Act § 12 — Civil Liability for Selling (15 U.S.C. § 77l). It is the Securities Act analog to Exchange Act § 20(a), which provides controlling person liability for Exchange Act violations including Rule 10b-5 claims.

Statutory Text

Any person who controls any person liable under §§ 11 or 12 shall also be liable jointly and severally with and to the same extent as such controlled person to any person to whom such controlled person is liable, unless the controlling person had no knowledge of or reasonable grounds to believe in the existence of the facts by reason of which the liability of the controlled person is alleged to exist.

Elements

To establish controlling person liability under § 15:

  1. Primary violation: A controlled person (the “primary violator”) must be liable under § 11 or § 12
  2. Control: The defendant exercised control over the primary violator
  3. No additional culpability element required for plaintiff — burden shifts to defendant to prove the defense

Who Is a “Controlling Person”?

Control is broadly interpreted. Examples of controlling persons:

  • Parent companies controlling a subsidiary issuer
  • Majority shareholders with practical ability to direct management
  • Corporate officers (CEO, CFO, general counsel) who directed or had power to direct the conduct at issue
  • Venture capital funds or private equity sponsors with board control or blocking rights
  • Directors who dominated board decision-making

The test focuses on practical ability to control, not just formal ownership. Courts look at:

  • Percentage of stock ownership
  • Board representation and voting power
  • Management agreements or contractual rights
  • Actual exercise of control in day-to-day operations

Defense: Good Faith and No Inducement

The controlling person may avoid liability by showing:

  • Good faith: The controlling person acted in good faith AND
  • No inducement / no knowledge: The controlling person did not directly or indirectly induce the act or acts constituting the violation or cause of action (some circuits also require showing no “culpable participation”)

This defense is narrower than it might appear — a controlling person cannot simply claim ignorance if they had the means to know and failed to inquire.

Joint and Several Liability

When § 15 liability attaches, the controlling person is jointly and severally liable — the plaintiff may recover the full judgment from the controlling person, the primary violator, or any combination. This makes controlling persons attractive co-defendants because they often have deeper pockets than the primary violator.

Most courts analyze both provisions similarly, though some circuit courts apply slightly different standards for what the defendant must show to prove the defense.

Practical Significance

Section 15 is most commonly invoked in securities class actions arising from IPOs or other registered offerings. Plaintiffs routinely name:

  • The issuer (absolute liability under § 11)
  • All signatories and directors (§ 11 defendants)
  • Underwriters (§ 11 defendants)
  • Parent companies, major investors with board seats (§ 15 controlling persons)

The controlling person theory allows plaintiffs to reach parties who were not themselves active in the offering but exercised power over those who were.
