Quick Answer
The waiting period runs from filing to effectiveness. Oral offers are generally permitted; written offers need a lawful prospectus form or exemption. Sales await effectiveness. Permitted pricing omissions must be completed under the applicable filing schedule, not a universal next-day rule. Shelf supplements update takedown disclosure. Preliminary-prospectus dissemination can affect the SEC's acceleration decision.
The waiting period is when most of the marketing for a deal happens. The principal has to know which communications are permitted, which prospectus form satisfies which delivery duty, and what mechanical conditions (legend, filing, accompanied delivery) attach to each.
What Is Permitted in the Waiting Period
| Activity | Status |
|---|---|
| Oral offers | Permitted (one-on-one calls, road-show presentations, sales-desk conversations) |
| Written offers via preliminary prospectus | Permitted with the prelim's red legend |
| Written offers via tombstone advertisement | Permitted with the prescribed tombstone legend |
| Written offers via free-writing prospectus | Permitted subject to issuer and offering eligibility, applicable filing and legend conditions, and added prospectus-delivery conditions for unseasoned and non-reporting issuers |
| Sales | Prohibited until the registration statement is effective |
The waiting period unlocks oral offers and a controlled set of written offers. The pre-filing silence rule no longer applies; the rule is now "communicate within these forms or it is an illegal prospectus."
Exam Tip: Gotchas
- Sales remain prohibited in the waiting period. A signed indication of interest is a non-binding offer, not a sale. Cash and shares cannot change hands until effectiveness.
- Filing generally permits oral offers. Pre-filing offers need a valid exemption, such as qualifying testing-the-waters communications. Oral and written formats can have different conditions in every phase.
The Preliminary (Red-Herring) Prospectus
The preliminary prospectus is the principal vehicle for written offers in the waiting period. It is also called the red herring because of the red legend printed on the cover page.
| Element | What It Looks Like |
|---|---|
| Status | Alternative prospectus authorized by the preliminary prospectus rule |
| Red legend (cover page) | States that the registration statement has been filed but is not yet effective, that the prospectus is subject to completion, and that no offer to buy can be accepted before effectiveness |
| What may be omitted | Pricing-related information (final price, underwriting discount, net proceeds) - omission permitted by the pricing-omitted mechanic |
| Use | Substitutes for the final prospectus to satisfy written-offer requirements during the waiting period |
The red herring is a complete-disclosure document minus the pricing terms. Investors get a substantive description of the issuer, the business, the risk factors, the use of proceeds, the financials, and the structure of the offering. Pricing fills in at effectiveness.
Exam Tip: Gotchas
- The red legend warns the prospectus is preliminary; it does NOT make the prospectus an "offer." The preliminary prospectus rule authorizes the prelim as an alternative prospectus that satisfies the prospectus requirements for written offers. The legend manages investor expectations; it does not change the prelim's status.
- The prelim may NOT yet be the basis of a sale. Sales require the final prospectus. The prelim covers waiting-period communications; the final covers post-effective sales.
- Pricing-related information may be omitted, not the entire offering structure. Issuer narrative, risk factors, MD&A, and use of proceeds must be in the prelim. Only the pricing block is allowed to wait until effectiveness.
Pricing Information Omitted at Effectiveness
For eligible cash offerings, the pricing-omission framework permits specified omissions at effectiveness, subject to required undertakings and later filing. The completed prospectus is generally due no later than the second business day after the earlier of pricing or first use after effectiveness under the applicable pricing-filing category.
| Step | What Happens |
|---|---|
| Tuesday: Pricing | Offering price is determined |
| Wednesday: Effectiveness | The registration statement becomes effective with permitted omissions |
| Thursday: Filing deadline | The second business day after Tuesday pricing is the deadline in this example, assuming no holidays or earlier relevant use |
The pricing-omitted mechanic avoids the need for a post-effective amendment to fill in the price. Without it, every IPO would require a post-effective amendment for the final price, lengthening the process by days.
Exam Tip: Gotchas
- The pricing-omitted mechanic applies only to CASH offerings. Stock-for-stock business combinations and other non-cash deals are outside its scope.
- Permitted omissions can be completed without an amendment. The actual filing category determines the deadline; it is not universally the day after effectiveness.
- The fifteen-business-day rule is a separate limit. If omitted information is not supplied within that outer period, an effective post-effective amendment is required. That does not extend an earlier prospectus-filing deadline; a missed required filing must be made as soon as practicable after discovery.
Shelf-Takedown Prospectus Supplements
The shelf-takedown framework governs prospectus updates for shelf offerings:
| Mechanism | What It Permits |
|---|---|
| Base prospectus omits permitted information | Qualifying shelf offerings may omit specified unavailable information or selling-holder details under the applicable conditions; not every omission is permitted for every issuer |
| Prospectus supplement | Each takedown is supplemented with a prospectus supplement filed via the shelf-supplement filing path |
| Incorporated Exchange Act report | A 10-K, 10-Q, or 8-K filed after the base shelf can update or correct the base prospectus by incorporation by reference |
The principal supervising a shelf takedown has to confirm the supplement covers what the base did not, that the supplement was filed on time, and that the disclosure framework is intact across base + supplement + incorporated reports.
Exam Tip: Gotchas
- Shelf-takedown supplements cover SHELF takedowns; the pricing-omitted mechanic covers INITIAL effectiveness pricing. They are companion mechanics. The pricing-omitted mechanic omits pricing at first effectiveness; the shelf-takedown framework omits supplemental detail across multiple takedowns.
- An 8-K filed after the base shelf can become part of the prospectus by incorporation. This is the "live" disclosure framework: the prospectus is not just the document on file but the document plus everything incorporated. The supervising principal verifies the incorporation is properly noted in the supplement.
Tombstone Advertisements
The tombstone is the "factual identifier" carve-out. A communication that complies with the tombstone-ad safe harbor is expressly excluded from the definition of "prospectus" - it can be used in the waiting period and the post-effective period.
| Permitted Content (Issuer Information) | Permitted Content (Security Information) |
|---|---|
| Name, address, phone, email | Title and amount of securities |
| Principal-office and investor-relations contacts | Designation as preferred, convertible, or secured |
| Country / state of organization | Price (if known) |
| Geographic areas of operation | Brief description of intended use of proceeds |
| Brief indication of the issuer's general type of business | Type of underwriting |
| Names of underwriters and offering participants |
| Required Legend | When |
|---|---|
| Pre-effective tombstone | Generally states that registration is filed but not effective and securities cannot be sold or offers accepted before effectiveness, with required prospectus-source information |
| Post-effective tombstone | Generally includes the required prospectus-source information; specific limited-content or prospectus-delivery exceptions can remove these notice requirements |
A tombstone must stay within its permitted content. Promotional claims beyond those limits lose this exemption. The principal must then assess another lawful communication category before authorizing use; losing the tombstone exemption is not itself proof that no alternative is available.
Think of it this way: The tombstone is the announcement, not the pitch. It tells the market who the issuer is, what is being sold, who the underwriters are, and where to get the prospectus. Anything that goes beyond identifying the deal pushes the ad into prospectus territory.
Exam Tip: Gotchas
- Tombstones can disclose permitted pricing information and underwriter names. The pre-filing notice has different content limits, including no underwriter names and specific provisions for certain offering terms.
- Selling language can defeat the tombstone exemption. A proposed communication must then fit another lawful category and satisfy its conditions before use.
- The pre-effective vs. post-effective tombstone legends are different. Pre-effective: "registration not yet effective; not an offer." Post-effective: "where to obtain a prospectus." Using the wrong legend in the wrong phase is a tombstone-ad violation.
Distribution of the Preliminary Prospectus
In considering acceleration of effectiveness, the SEC assesses reasonable steps to make preliminary disclosure conveniently available through expected underwriters and dealers, subject to specified exceptions:
- The ordinary dissemination process supplies preliminary prospectuses to:
- Dealers who are reasonably expected to be invited to participate, and
- Underwriters in numbers reasonably calculated to allow each to give the prospectus to interested customers
Reasonable quantities should be supplied a reasonable time before anticipated effectiveness. The rule has exceptions, including specified competitive-bid, continuing-fund, rights, exchange-offer, and business-combination situations, and does not require unlawful distribution in a state.
The statutory default is separate from acceleration. Without a delaying amendment or SEC action preventing effectiveness, a registration statement can become effective after the ordinary 20-day waiting period. Preliminary-prospectus distribution to expected dealers and underwriters informs an acceleration request; it is not a separate condition for default effectiveness.
Exam Tip: Gotchas
- The acceleration-dissemination rule is enforced through ACCELERATION, not through a free-standing prohibition. It does not directly prohibit a poorly distributed prelim; it conditions the SEC's willingness to accelerate effectiveness on adequate distribution. In practice, that is the same lever: no acceleration means a deal does not go effective on the schedule the underwriters want.
- The dissemination duty applies to the SYNDICATE distribution, not retail customers. The duty is to get the prelim into dealer and underwriter hands so they can pass it to interested customers. The retail-delivery duty is the broker-dealer prospectus-delivery rule, covered in the post-effective topic.
What Should You Check on Exam Day?
- Can you state that sales remain prohibited throughout the waiting period even though oral offers become permitted once filing occurs?
- Can you distinguish the pricing-filing deadline from the separate fifteen-business-day omission limit?
- Can you distinguish what a waiting-period tombstone may disclose, including price and underwriter names, from the pre-filing proposed-offering notice?
- Do you know that the acceleration-dissemination rule conditions SEC acceleration on distributing the preliminary prospectus through dealers and underwriters, not retail customers?
