Waiting Period
The Waiting Period is the stage of a registered securities offering after the Registration Statement has been filed but before it has become effective.
How it works
During the Waiting Period, the issuer and underwriters can market the offering within the Securities Act communication rules, but they cannot complete sales of the registered securities. Oral offers are generally permitted, and written offers can use a Preliminary Prospectus, qualifying Free Writing Prospectus or another permitted communication. The SEC can review the Registration Statement during this period and provide comments that the issuer addresses before effectiveness.
The period begins with filing
Before filing, the offering is in the pre-filing stage governed by the more restrictive Section 5(c) offer rules.
The period ends at effectiveness
Once the Registration Statement becomes effective, the transaction moves into the post-effective stage and registered sales can be completed.
Marketing can occur during the period
Roadshows, Preliminary Prospectuses and permitted Free Writing Prospectuses can be used subject to their specific rules.
Sales cannot close yet
The issuer can solicit interest or offers within the legal framework, but acceptance and sale must wait for effectiveness.
Worked example: SEC comments extend the period
An issuer expects a two-week marketing period, but a new SEC comment requires an amendment. Effectiveness is delayed, extending the Waiting Period.
Why the period matters to investors
Information and pricing can evolve as the issuer responds to comments, markets the deal and receives investor feedback.
Common mistakes
Assuming the Waiting Period always lasts 20 days; treating filing as effectiveness; assuming written communications are unrestricted after filing; and confusing the Waiting Period with a trading blackout.
Example
An IPO Registration Statement is filed on June 1 and declared effective on June 24. The period between those dates is the Waiting Period, during which the issuer conducts its Roadshow and distributes the Preliminary Prospectus.

Professional note
The Waiting Period is not a mandatory fixed number of calendar days in modern offering practice. Its practical length depends on SEC review, issuer readiness and the effectiveness process.
