A selling-group dealer that is not an underwriter sells shares of a new registered issue to its own customers. The syndicate is relying on the access equals delivery mechanism, so no prospectus is being transmitted to anyone. The dealer assumes that any written notice of the registration is the lead underwriter's business. What is the dealer's own position under Rule 173?

The notices the lead underwriter sends discharge the obligation across the selling group, one notice per purchaser being all the rule contemplates

It owes the written notice to each of its own purchasers, because the rule puts the obligation on participating dealers as well as on underwriters

It owes nothing, the duty running to the issuer, which notifies purchasers of the registration through its transfer agent as the shares are booked

It owes a notice only to a customer who asks for one, the public availability of the filing answering for every other purchaser in the offering

An issuer in a registered offering learns that its underwriters will send each purchaser the brief written notice that goes with reliance on the access equals delivery mechanism. What does that notice do to the issuer's own disclosure position?

It becomes part of the issuer's prospectus for liability purposes, so that an inaccuracy in the notice is actionable as a prospectus misstatement

It adds a short-form disclosure document to the offering, which the issuer must prepare and keep current for as long as the distribution continues

Nothing: the notice reproduces no part of the prospectus, is not itself a prospectus under the Act, and lays no further disclosure obligation on the issuer

It obliges the issuer to file a short summary of the prospectus with the Commission alongside the final prospectus, for the underwriters to use in the notice

The access equals delivery model rests on the premise that a prospectus filed with the Commission can be retrieved by anyone with an internet connection. Why was a notification requirement built into that model instead of leaving purchasers to the filing alone?

Because some purchasers, retail buyers unfamiliar with the Commission's filing system above all, would not think to look for a filed prospectus unless told one existed

Because the Commission may not treat a filing as delivery of a document unless each purchaser is separately told, in writing, that the filing has been made

Because a filed prospectus becomes publicly retrievable only after someone requests it from the Commission, and the notice is what prompts purchasers to make that request

Because the filing system holds registration statements rather than final prospectuses, so a purchaser has to apply to the selling firm for the prospectus itself

A firm is settling the standard wording of the notices it sends purchasers in registered offerings, and wants them as short as the rule allows. What does the rule require the notice to carry?

The issuer and class of securities sold, the date the registration statement became effective, and a statement that a paper copy of the prospectus may be requested from the firm

A statement that the sale was made under a registration statement, the issuer and class of securities sold, and enough information for the purchaser to reach the final prospectus on file

A statement that the sale was made under a registration statement, together with the date of the sale and the number of securities the purchaser bought, and the identity of the firm that effected it

A statement that the sale was made under a registration statement, the identity of the issuer, and a statement of the purchaser's right to rescind the purchase should the prospectus prove materially misleading in any respect

A firm would rather print its notice of the registration on the face of the trade confirmations it already sends purchasers than mail a separate document. Is that course open to it under Rule 173?

Only where the purchaser has consented in writing to receive the notice that way, written consent being the condition of any combined communication

No: the notice has to be a standalone communication, a confirmation serving a different statutory purpose and being unable to carry it

Yes: the rule mandates no particular form, so the notice may be carried on the confirmation or sent as a separate communication

Not unless the firm files the combined document with the Commission, a notice merged into a confirmation forming part of the offering record

A dealer emails every purchaser in a registered offering a complete copy of the final prospectus, well inside the window the rule allows for notifying them. It now asks whether it must also send each of them the written notice of the registration. What is the position?

The notice is due where the prospectus went out electronically, a paper copy of the prospectus being the only form of delivery that dispenses with it

The notice is still due, the rule requiring it of every purchaser in a registered offering whether or not the prospectus itself has reached them

The notice is still due unless each purchaser confirms receipt of the emailed prospectus, a record of which the dealer must keep

No separate notice is called for: delivering the prospectus itself answers for the deemed compliance framework and the notification requirement together

A firm's institutional clients — pension funds and insurers that subscribe to the Commission's filing system themselves — take most of a registered offering. The firm argues that telling such buyers about the registration adds nothing they cannot already see for themselves. How does Rule 173 treat those purchasers?

They are owed the notice on the same footing as any other purchaser, the rule drawing no line by a buyer's sophistication or resources

They fall outside the rule, which reaches only those purchasers who cannot be expected to follow the Commission's filings for themselves

They fall outside the rule once they have acknowledged in writing that they follow the Commission's filings, the acknowledgement answering for the notice

They are owed the notice where the offering also goes to retail buyers, an offering taken up wholly by institutions falling outside the rule

Long after a new issue was distributed, a dealer sells some of those shares to a customer in the ordinary secondary market. By then the Securities Act prospectus delivery period for the security has run out. Must the dealer send that customer a notice of the registration?

Yes, because the shares were issued under a registration statement, and it is the existence of that registration that the notice exists to convey

No: with the underlying delivery obligation lapsed there is nothing for the access equals delivery mechanism to satisfy, so no notice requirement arises

Yes, and the obligation continues for as long as the issuer keeps a current prospectus on file with the Commission for the class of securities

Yes, unless the dealer had taken the shares into its own inventory before the delivery period expired, which ends the obligation early

An underwriter in a registered offering satisfied every condition of the access equals delivery mechanism — the final prospectus was on file and anyone could retrieve it — but sent no written notice of the registration to any purchaser, treating the notice as a courtesy it could do without. Where does that leave the firm under the Securities Act?

Its obligations are discharged, since each purchaser could retrieve the prospectus and the mechanism asks for nothing beyond that public availability

Its obligations are discharged, the notification requirement standing apart as a rule whose breach is answered for on its own account

Its obligations are not fully discharged, notification being a condition of the access equals delivery regime rather than an optional addition to it

Its obligations stand in suspense until a purchaser complains of never having been notified, at which point the notice has to be sent to that purchaser

An examination of a broker-dealer's prospectus delivery practices finds written supervisory procedures that address the notification requirement, but the firm has kept no copies of the notices it sent and no log of them. What does that leave the firm unable to do?

Fall back on the trade confirmations it archived, which examination staff treat as standing in for records of the notices

Show that a principal approved the procedures before the distribution began, which the notification requirement separately calls for

Establish that it relied on the access equals delivery mechanism at all, which the notices and nothing else can prove

Evidence that the notices went out at all, which staff expect a firm to show from retained records of them

SEC Rule 173: The Access Equals Delivery Notice Requirement

SEC Rule 173, codified at 17 C.F.R. § 230.173 under the Securities Act of 1933, requires underwriters and dealers participating in a registered offering to provide purchasers with a written notice confirming that the securities being sold are subject to a registration statement filed with the Securities and Exchange Commission.

Rule 173 operates as the investor-facing component of the access equals delivery framework established by Rule 172, ensuring that purchasers are informed of the existence of the registration statement and the prospectus filed with the Commission, even where no physical or electronic prospectus is transmitted directly to them. The rule functions as a practical bridge between the statutory prospectus delivery obligation and the modern electronic filing environment in which that obligation is now discharged.

Overview and Regulatory Purpose

Prior to the adoption of the access equals delivery model, prospectus delivery obligations under the Securities Act of 1933 were satisfied by the physical or electronic transmission of the prospectus document itself. The transition to deemed compliance through EDGAR filing under Rule 172 eliminated the requirement to transmit the full prospectus, but it created a corresponding need to ensure that individual purchasers were not left entirely uninformed about the existence of the registration statement governing the securities they were acquiring. Rule 173 addresses this need by requiring a brief written notice — distinct from and considerably shorter than the prospectus itself — to be delivered to each purchaser confirming the registered nature of the transaction.

The regulatory purpose of Rule 173 is therefore informational rather than substantive. The notice does not reproduce the content of the prospectus, does not constitute a prospectus for the purposes of Section 10 of the Securities Act, and does not impose additional disclosure obligations on the issuer.

Its function is to alert the purchaser that a full prospectus is on file with the Commission and accessible through EDGAR, thereby preserving the investor's ability to consult the document and to exercise any rights arising from its contents, including the right of rescission under Section 12(a)(2) of the Securities Act where the prospectus contains a material misstatement or omission.

Statutory Authority and Rulemaking History

Rule 173 derives its statutory authority from Section 19(a) of the Securities Act of 1933, which grants the Commission rulemaking authority to prescribe rules necessary or appropriate to carry out the provisions of the Act.

The rule was adopted alongside Rule 172 as part of the Securities Offering Reform package published in Securities Act Release No. 33-8591 in July 2005.

The two rules were designed as complementary instruments: Rule 172 extinguishes the obligation to transmit the full prospectus, and Rule 173 substitutes a minimal notification requirement that preserves the investor's awareness of the registration framework without reimposing the logistical burden of full prospectus distribution.

The Commission's 2005 adopting release noted that Rule 173 was intended to serve the informational interests of investors while maintaining the efficiency gains of the access equals delivery model. The release acknowledged that a small number of investors, particularly retail purchasers unfamiliar with the EDGAR system, might not spontaneously seek out a filed prospectus absent some notification of its existence. Rule 173 was designed to provide that notification in a form sufficiently brief to impose minimal administrative burden while sufficiently clear to alert a reasonable investor to the availability of the full disclosure document.

Key Provisions and Operative Requirements

Rule 173(a) imposes the notification obligation on underwriters and dealers that sell securities in a registered offering in reliance on the deemed compliance mechanism of Rule 172.

The notice must be provided to each purchaser no later than two business days following the date of the sale.

The two-business-day window reflects a deliberate balance between the practical constraints of post-trade processing and the investor's interest in timely notification. A notice delivered within this window is deemed to satisfy the Rule 173 obligation regardless of whether the purchaser has independently consulted the EDGAR filing.

The content requirements for the Rule 173 notice are minimal by design. The notice must state that the sale was made pursuant to a registration statement or in a transaction in which a final prospectus would have been required to be delivered in the absence of Rule 172. It must identify the issuer and the class of securities sold and must direct the purchaser to the Commission's EDGAR database or otherwise provide information sufficient to enable the purchaser to locate the final prospectus. No specific form is mandated by the rule, and the notice may be incorporated into a trade confirmation or delivered as a standalone communication, provided it meets the content requirements and the two-business-day delivery deadline.

Rule 173(b) provides that the notice requirement does not apply where the underwriter or dealer has actually delivered a copy of the final prospectus to the purchaser, whether in paper or electronic form, within the two-business-day window. In such cases, the full prospectus delivery satisfies both the Rule 172 deemed compliance framework and the Rule 173 notification requirement simultaneously, and no separate notice is necessary.

Scope of Application

Rule 173 applies to underwriters and dealers participating in registered offerings conducted in reliance on Rule 172's access equals delivery mechanism. The obligation attaches at the point of sale and must be discharged within two business days of that event. It applies to all categories of purchaser, including institutional and retail investors, without distinction based on the sophistication or resources of the buyer.

The rule does not apply to offerings conducted outside the Rule 172 framework — including offerings exempt from registration under Regulation D, Regulation A, or Section 4(a)(2) of the Securities Act — since those transactions do not involve a registered prospectus to which the notice could direct the purchaser. Similarly, the rule does not apply where the underwriter or dealer delivers the full prospectus directly, since such delivery renders the notice requirement redundant under Rule 173(b).

Secondary market transactions conducted by dealers after the expiration of the applicable prospectus delivery period under Section 4(3) of the Securities Act are also outside the scope of Rule 173, since the prospectus delivery obligation itself has lapsed and no Rule 172 deemed compliance is required.

Rule 173 is structurally inseparable from Rule 172. The two rules together constitute the operative mechanism through which the access equals delivery standard functions in practice: Rule 172 extinguishes the obligation to transmit the full prospectus, and Rule 173 replaces that obligation with a minimal notification requirement. An underwriter or dealer that relies on Rule 172 without complying with Rule 173 has not fully discharged its obligations under the Securities Act framework, since the notification component is a condition of the overall access equals delivery regime rather than a standalone optional requirement.

The Rule 173 notice interacts with the broader prospectus liability framework under Section 12(a)(2) of the Securities Act. Because the notice directs the purchaser to the filed prospectus, it preserves the purchaser's access to the document from which any Section 12(a)(2) claim would arise. A purchaser who receives a Rule 173 notice and subsequently discovers a material misstatement or omission in the filed prospectus retains the full range of remedies available under Section 12(a)(2), including rescission of the purchase. The notice therefore serves an incidental but significant function in the enforcement architecture of the Securities Act.

Rule 173 also intersects with Rule 424(b), which requires the filing of a final prospectus with the Commission following the effective date of the registration statement. The Rule 173 notice can only meaningfully direct a purchaser to a prospectus that has been filed pursuant to Rule 424(b); a notice issued before the Rule 424(b) filing is complete would be unable to direct the purchaser to the relevant document and would therefore fail to satisfy the informational purpose of the rule.

Amendment History and Regulatory Evolution

Rule 173 has not been materially amended since its adoption in 2005, consistent with the broader stability of the access equals delivery framework of which it forms a part. The Commission's subsequent rulemaking in the registered offering space has not revisited the substantive requirements of the rule, and no significant legislative developments have required its modification.

Staff guidance issued through Compliance and Disclosure Interpretations has addressed practical questions about Rule 173 compliance, including whether hyperlinks embedded in trade confirmations satisfy the requirement to direct purchasers to the EDGAR filing. The Commission's staff has confirmed that electronic delivery of the Rule 173 notice, including by means of a hyperlink to the relevant EDGAR filing page, is consistent with the rule's requirements provided the electronic communication is delivered within the two-business-day window and the hyperlink provides direct access to the filed prospectus.

Enforcement Context and SEC Action Patterns

As with Rule 172, enforcement actions specifically targeting Rule 173 in isolation are uncommon. The rule's notification requirement is sufficiently straightforward that compliance failures are rarely the primary subject of Commission enforcement proceedings. Where Rule 173 deficiencies have been identified, they have typically arisen in the context of broader examination findings concerning prospectus delivery practices, trade confirmation procedures, or recordkeeping obligations applicable to broker-dealers under the Securities Exchange Act of 1934.

The Office of Examinations has included prospectus delivery practices, encompassing both Rule 172 and Rule 173 compliance, within its periodic review of broker-dealer operational controls. Examination staff have noted that broker-dealers should maintain written supervisory procedures specifically addressing the two-business-day notification requirement and should retain records of Rule 173 notices sufficient to demonstrate compliance upon examination.

Examination Relevance and Key Takeaways

Rule 173 is tested at the Series 7 and SIE level in conjunction with Rule 172 as part of the broader topic of prospectus delivery obligations in registered offerings. Candidates should understand the two-business-day delivery requirement and the distinction between a Rule 173 notice and the prospectus itself — the notice is not a prospectus and does not reproduce prospectus content. It is a brief communication directing the purchaser to the filed document on EDGAR.

A frequent examination concept involves the circumstances under which Rule 173 is not required — specifically where the underwriter or dealer delivers the full prospectus directly to the purchaser within two business days, rendering the separate notice redundant. Candidates should also understand that Rule 173 applies only in the context of registered offerings conducted in reliance on Rule 172 and does not extend to exempt transactions or secondary market sales outside the prospectus delivery period.

The key points to retain are these. Rule 173 requires underwriters and dealers relying on Rule 172's access equals delivery mechanism to deliver a written notice to each purchaser within two business days of the sale. The notice must identify the issuer, the securities sold, and direct the purchaser to the filed prospectus on EDGAR. It is not itself a prospectus and does not reproduce prospectus content. Rule 173 is not required where the full prospectus has been delivered directly. Together, Rules 172 and 173 form the complete access equals delivery framework under the Securities Act of 1933, replacing physical prospectus distribution with a system premised on universal electronic access to Commission filings.
