What you'll learn
- State what Section 5 prohibits and the three periods it creates around a registered offering
- Distinguish an exempt SECURITY under Section 3 from an exempt TRANSACTION under Section 4
- State the Section 4(a)(2) private-offering exemption and the Ralston Purina test for when it applies
- Explain why the burden of proving an exemption falls on the person claiming it
- Describe the rescission remedy under Section 12(a)(1) and why a failed exemption is so costly
The Securities Act of 1933 does not say that securities must be good. It says that they must be registered, and then it lists the situations in which they need not be. Every private placement you will ever sell lives inside one of those situations, and the whole of Function 1 on this exam is really one question asked many ways: which exemption, and were its conditions met? It is worth knowing the scale of what those exceptions carved out. The SEC reported 34,553 Regulation D offerings raising 2.4 trillion dollars in 2025, against 374 registered initial public offerings raising 70 billion and 1,694 registered corporate bond offerings raising 1.25 trillion. The exception to registration is now considerably larger than the rule.
What Section 5 actually prohibits
Section 5 of the Securities Act, codified at 15 U.S.C. 77e, is three prohibitions rather than one, and keeping them separate is worth the effort because the exam separates them.
Section 5(c) makes it unlawful to OFFER a security before a registration statement has been filed. Note the verb. Not to sell, to offer — and "offer" is defined broadly enough that enthusiasm in an email can be one.
Section 5(a) makes it unlawful to SELL or to deliver after sale unless a registration statement is in effect.
Section 5(b) governs the prospectus: it makes it unlawful to transmit a prospectus that does not meet the statute's requirements, and unlawful to deliver a security for sale unless it is preceded or accompanied by a final prospectus.
Together these create the three periods that structure a registered offering. Before the registration statement is filed, nothing may be offered at all. Between filing and effectiveness — the waiting period — the security may be offered orally and by preliminary prospectus, but not sold. After effectiveness, it may be sold, with the final prospectus delivered.
You will not spend your career in registered offerings. But you must know this structure, because a private placement is defined by its escape from it, and because the communication rules in Module 3 are mostly about not accidentally re-entering it.
Two different kinds of exemption
This is the distinction candidates most often blur, and it is worth being exact about it, because it changes what travels with the security.
An EXEMPT SECURITY under Section 3 is exempt because of what it is. Section 3(a) lists the classes: securities issued or guaranteed by the United States government or by a state or municipality; securities issued by banks; short-term commercial paper with a maturity at issuance not exceeding nine months; securities of non-profit religious, educational and charitable organizations; securities issued by savings and loan associations and by farmers' cooperatives; and insurance policies and annuity contracts issued by a regulated insurer. The exemption attaches to the instrument. It does not expire, and it survives resale.
An EXEMPT TRANSACTION under Section 4 is exempt because of how the security changes hands. The instrument itself is an ordinary, unregistered security. What Section 4 exempts is a particular transaction in it.
That difference has a consequence you will be tested on. Because a Section 4 exemption belongs to the transaction, the security emerging from it is RESTRICTED: it was never registered, so the next person to sell it needs their own exemption. This is why restricted securities exist at all, why Rule 144 exists to let people out of them, and why an investor in a private placement is buying an illiquid position whether or not anyone said so.
The exemption belongs to the security, or it belongs to the transaction. Ask which, and most of the confusion resolves.
Section 4(a)(2) and the Ralston Purina test
The transaction exemptions in Section 4(a) matter to a private-placement representative in a specific order.
Section 4(a)(1) exempts "transactions by any person other than an issuer, underwriter, or dealer." This is the ordinary investor's exemption — it is why you may sell shares you own without registering anything, and why the definition of "underwriter" carries so much weight in the resale rules.
Section 4(a)(2) exempts "transactions by an issuer not involving any public offering." Nine words, and they are the foundation of the entire private placement market.
The statute does not define "public offering," and for twenty years nobody was sure what it meant. In 1953 the Supreme Court decided SEC v. Ralston Purina Co. The company had offered treasury stock, without registration, to what it called its "key employees" — a category it defined loosely enough to include anyone eligible for promotion or sympathetic to management. The lower courts accepted the exemption on the ground that the selection bore a sensible relation to the class chosen.
The Supreme Court reversed, and the sentence that did it is the one to remember: "the applicability of Section 4(1) should turn on whether the particular class of persons affected need the protection of the Act. An offering to those who are shown to be able to fend for themselves is a transaction not involving any public offering."
So the test is not the number of offerees. It is their access to information. The Court was explicit that the issuer's motives "fade into irrelevance" once you see that the question turns on the knowledge of the offerees, and that the right focus is "the need of the offerees for the protections afforded by registration."
That is why Regulation D, which you will meet in the next lesson, is built around investor sophistication and mandated disclosure rather than around a headcount. It is Ralston Purina turned into a rulebook.
Who has to prove it, and what happens if they cannot
Ralston Purina settled a second point that is at least as important commercially: the burden of proof.
The Court held that "imposition of the burden of proof on an issuer who would plead the exemption seems to us fair and reasonable." An exemption is an affirmative defence. Nobody grants it in advance, no regulator blesses it, and there is no certificate. You conduct the offering, and if it is ever challenged, the person relying on the exemption must establish that every condition was met.
This is why the documentation habits taught in Module 4 are not bureaucracy. The subscription agreement, the investor questionnaire, the accreditation verification file and the Form D are the evidence that the exemption was available. An offering that was in fact perfectly proper but cannot be shown to have been proper is in a poor position.
What follows a failed exemption is set out in Section 12 of the Act, 15 U.S.C. 77l. Section 12(a)(1) gives any person who bought a security sold in violation of Section 5 the right to recover the consideration paid, with interest, less any income received, on tender of the security — or damages if they no longer hold it.
Read that again, because it is unlike most securities liability. There is no requirement to prove fraud, reliance, or even that the investment lost money. Selling an unregistered security in a transaction that turns out not to have been exempt gives the buyer a right of rescission on strict liability. In a falling market every investor in a defective offering discovers this at once.
Section 12(a)(2) is the companion: liability for offering or selling by means of a prospectus or oral communication containing an untrue statement of material fact, or omitting one necessary to make the statements not misleading, where the seller cannot sustain the burden of proving that they did not know and could not with reasonable care have known. Again the burden sits on the seller.
A private placement therefore carries two distinct risks for the firm that distributes it: that the exemption fails, and that the disclosure was inadequate. Module 3's lesson on due diligence exists because of the second.
Key takeaways
- ·Section 5 prohibits offers before filing, sales before effectiveness, and delivery without a compliant prospectus — a private placement is defined by its escape from all three.
- ·An exempt SECURITY (Section 3) is exempt for what it is and stays exempt on resale; an exempt TRANSACTION (Section 4) leaves behind a restricted security that needs its own exemption to be resold.
- ·Section 4(a)(2) exempts transactions by an issuer not involving any public offering, and Ralston Purina makes the test the offerees' access to information, not their number.
- ·An exemption is an affirmative defence: the person claiming it must prove every condition was met, which is why the offering file is the exemption.
- ·Section 12(a)(1) gives a buyer rescission on strict liability when Section 5 was violated — no fraud, no reliance and no loss need be shown.
Regulation D is the safe harbour that turns Ralston Purina's standard into conditions you can actually satisfy and document. It is the next lesson, and it is the densest one in the course.
