Between full registration and a private placement sits Regulation A. And a registration need not be used at once: a shelf lets an issuer sell later, for a limited time.
Regulation A: a public offering without full registration
Regulation A is an exemption from Securities Act registration for smaller offerings to the public. The issuer files an offering statement with the SEC. Its disclosure document is the offering circular, a scaled-down version of what a registration statement holds. Sales may begin only after the SEC qualifies the offering statement. Qualification plays the part that effectiveness plays in a registered offering.

There are two tiers. Tier 1 allows up to $20 million in a 12-month period; Tier 2 allows up to $75 million. Tier 2 issuers must include audited financial statements and file annual, semiannual and current reports with the SEC. Tier 1 issuers need audited statements only if they already have them. Tier 2 buyers need not be accredited, but a non-accredited buyer faces an investment limit unless the shares will be listed on an exchange.
The tiers also differ on state law. A Tier 1 issuer must register or qualify the offering in each state where it offers or sells. A Tier 2 issuer does not have to, though the states keep their enforcement and antifraud authority and may charge filing fees. Tier 2 trades more SEC disclosure for relief from state-by-state review.
A shelf registration has a clock
A shelf registration under Rule 415 registers securities once for an offering made on a continuous or delayed basis. It is a registration, not an exemption. For an issuer’s own delayed offering registered on Form S-3, and for an automatic shelf, sales are allowed only while not more than three years have passed since the registration statement first became effective. Before the three years end, the issuer may file a new registration statement to keep selling.
Exam terms (6)
- Regulation A
- An exemption from registration for smaller public offerings, in two tiers.
- Offering circular
- The disclosure document in a Regulation A offering statement.
- Qualification
- The SEC step after which Regulation A sales may begin; the counterpart of effectiveness.
- Tier 1 / Tier 2
- Up to $20 million with state registration / up to $75 million with audits, ongoing reports and no state registration.
- Shelf registration
- One registration under Rule 415 for securities sold later, on a continuous or delayed basis.
- Initial effective date
- The day a registration statement first takes effect; an issuer’s shelf clock runs three years from it.
Two tiers of Regulation A
| Tier 1 | Tier 2 | |
|---|---|---|
| Most raised in 12 months | $20 million | $75 million |
| Audited financial statements | Only if already prepared | Required |
| SEC reports after the offering | An exit report after the offering | Annual, semiannual and current reports |
| State registration | Required in each state of sale | Not required; state antifraud law still applies |
Try it: A company wants to raise $12 million and then, two years later, $50 million. For each raise, say which tier fits and what the company must file with the SEC and with the states. Then say what a seasoned public company would use instead to sell shares in blocks over time, and how long that lasts.

Worked example
Pembury Biologics, a company that has never registered securities, needs $30 million from investors in many states.
- $30 million is above the Tier 1 limit of $20 million, so Tier 1 is out.
- Tier 2 allows up to $75 million. Pembury files an offering statement with an offering circular and audited financial statements.
- It may not sell until the SEC qualifies the offering statement.
- It does not register in each state, but the states keep their antifraud authority and may charge filing fees.
- After the offering it files annual, semiannual and current reports with the SEC for as long as Tier 2 requires.

The closest contrast
Tier 1: smaller, state review.
Tier 2: larger, SEC reports, no state registration.
This decides most tier questions. Check the amount first, then whether the issuer wants to avoid state-by-state registration.
Summary
- Regulation A is an exemption: an offering statement, an offering circular, and sales only after SEC qualification.
- Tier 1 allows up to $20 million and requires state registration.
- Tier 2 allows up to $75 million, requires audited financials and ongoing SEC reports, and is spared state registration.
- A shelf registration is a registration; an issuer’s own shelf sales stop three years after initial effectiveness.
