The obligations of a dealer (including an underwriter no longer acting as an underwriter in respect of the security involved in such transactions) to deliver a prospectus in transactions in a security as to which a registration statement has been filed taking place prior to the expiration of the 40- or 90-day period specified in section 4(3) of the Act after the effective date of such registration statement or prior to the expiration of such period after the first date upon which the security was bona fide offered to the public by the issuer or by or through an underwriter after such effective date, whichever is later, shall be subject to the following provisions:

No prospectus need be delivered if the registration statement is on Form F-6 (§ 239.36 of this chapter).

No prospectus need be delivered if the issuer is subject, immediately prior to the time of filing the registration statement, to the reporting requirements of section 13 or 15(d) of the Securities Exchange Act of 1934.

Where a registration statement relates to offerings to be made from time to time no prospectus need be delivered after the expiration of the initial prospectus delivery period specified in section 4(3) of the Act following the first bona fide offering of securities under such registration statement.

If (1) the registration statement relates to the security of an issuer that is not subject, immediately prior to the time of filing the registration statement, to the reporting requirements of section 13 or 15(d) of the Securities Exchange Act of 1934, and (2) as of the offering date, the security is listed on a registered national securities exchange or authorized for inclusion in an electronic inter-dealer quotation system sponsored and governed by the rules of a registered securities association, no prospectus need be delivered after the expiration of twenty-five calendar days after the offering date. For purposes of this provision, the term offering date refers to the later of the effective date of the registration statement or the first date on which the security was bona fide offered to the public.

Notwithstanding the foregoing, the period during which a prospectus must be delivered by a dealer shall be:

As specified in section 4(3) of the Act if the registration statement was the subject of a stop order issued under section 8 of the Act; or

As the Commission may provide upon application or on its own motion in a particular case.

Nothing in this section shall affect the obligation to deliver a prospectus pursuant to the provisions of section 5 of the Act by a dealer who is acting as an underwriter with respect to the securities involved or who is engaged in a transaction as to securities constituting the whole or a part of an unsold allotment to or subscription by such dealer as a participant in the distribution of such securities by the issuer or by or through an underwriter.

If the registration statement relates to an offering of securities of a “blank check company,” as defined in Rule 419 under the Act (17 CFR 230.419), the statutory period for prospectus delivery specified in section 4(3) of the Act shall not terminate until 90 days after the date funds and securities are released from the escrow or trust account pursuant to Rule 419 under the Act.

Any obligation pursuant to Section 4(3) of the Act and this section to deliver a prospectus, other than pursuant to paragraph (g) of this section, may be satisfied by compliance with the provisions of Rule 172 (§ 230.172).
