Final answer:
A paper copy of a prospectus is typically required for registered public offerings under SEC regulations, usually in the context of an IPO or subsequent offerings. While electronic methods are now common, paper delivery may still be required or requested.
Step-by-step explanation:
In the context of securities offerings, the type of prospectus that requires paper copy delivery is typically associated with a registered public offering governed by the U.S. Securities and Exchange Commission (SEC). Companies conducting an initial public offering (IPO) or subsequent public offerings must comply with SEC regulations, which include the delivery of a paper prospectus to potential investors. The final prospectus, containing detailed financial and business information, must be provided to the investor before or with the confirmation of sale. With the advent of electronic delivery methods and e-prospectuses, paper delivery requirements have become more flexible, but may still be necessary in certain contexts or upon request.
