A preliminary prospectus (often called a “red herring”) is used in a registered public offering—such as an IPO—before the final offering price and certain final terms are set. It typically contains extensive information about the issuer, including its business description, risk factors, intended use of proceeds, management, capitalization, and importantly, details about ownership and shareholdings (e.g., principal shareholders, insiders, and how ownership may change post-offering). That makes A (Ownership structure) the correct answer.

Choice B is incorrect because “anticipated trading volume” is not a standard required disclosure item in a preliminary prospectus. While a prospectus may discuss market and listing information, projected trading volume is speculative and generally not presented as a typical disclosure item. Choice C is incorrect because the SEC does not approve the merits of an offering; securities regulation is rooted in disclosure, not merit review. The SEC’s role is to require that material information is disclosed so investors can make informed decisions—not to judge whether the investment is “good.” Choice D is incorrect because FINRA does not “determine” a preliminary prospectus is accurate in that way; FINRA’s corporate financing review is focused on underwriting terms and arrangements for fairness/reasonableness under applicable rules, not certifying accuracy of issuer disclosures.

This question targets core SIE offering concepts: what a prospectus contains, what “red herring” means, and the principle that regulators require full and fair disclosure rather than guaranteeing investment quality.
