Issuing Corporate Securities - Tombstone Ads
Tombstone ads are the only form of advertising that is allowed during the cooling off period. A tombstone ad is an announcement and description of the securities to be offered. A tombstone ad lists the names of the underwriters, where a prospectus may be obtained, and a statement that the tombstone ad does not constitute an offer to sell the securities and that the offer may only be made by a prospectus. Tombstone ads are traditionally run to announce the new issue, but they are not required and do not need to be filed with the SEC.
