Offers of investments: the Part IV authorisation regime

Compiled by the Sitonce editorial team from the HKSI and SFC sources listed belowUpdated 5 min readFacts verified 5 September 2026
The short answer

Part IV of the Ordinance requires SFC authorisation before an advertisement, invitation or document offering securities or collective investment scheme interests is issued to the Hong Kong public. Authorising the offering document and authorising the scheme are separate steps, and offers confined to professional investors fall outside the regime.

Part IV is a gatekeeping regime and its logic is simple: if you want to ask the Hong Kong public for money, someone official looks at the document first. The complications are all at the edges. What counts as the public, what counts as an invitation, and which of two possible authorisations a question is actually talking about.

The core prohibition

An advertisement, invitation or document containing an invitation to the public to acquire securities or interests in a collective investment scheme must be authorised by the SFC before it is issued. Note the breadth. It is not limited to a formal prospectus. A marketing email can be an invitation, and the regime is drafted to catch the substance rather than the label.

ElementWhat it means
Advertisement, invitation or documentSubstance over form. The medium does not matter
To the publicThe critical qualifier. An offer that is not made to the public is not caught
Securities or CIS interestsDefined in Part I of the Ordinance, and the definitions do the real work
Authorised by the SFCRequired before issue, not after

Two authorisations, not one

This is where items are built. Authorisation of the offering document and authorisation of the scheme itself are separate steps under different provisions, and a question that describes one and offers the other as an answer is doing so deliberately. A fund can have an authorised offering document and still not be an authorised scheme, and the two decisions serve different purposes.

Authorisation is not endorsement

SFC authorisation means the document or the scheme meets the requirements for public offer. It is not a view on the merits of the investment, a comment on its likely performance, or any kind of guarantee. The SFC has no statutory objective to protect investors from loss.

The exemptions, and the one that matters

Part IV carries a set of exemptions, and in practice the important one is the professional investor route. An offer confined to professional investors does not engage the public offer regime at all, because it is not an offer to the public. That single carve-out is why so much of Hong Kong's institutional business runs on unauthorised documents without anyone breaking a rule.

Other exemptions exist for offers structured so that the pool of offerees is limited, or where the size of the investment puts it outside the retail sphere. The details sit outside what Paper 1 asks. What Paper 1 asks is whether you understand that the perimeter is drawn around the public, and that professional investors are treated as capable of looking after themselves.

The professional investor classification also changes what a firm must do for a client under the conduct rules, which is examined separately under business conduct. Two different regimes, one shared concept, and it is worth learning the concept once.

Open-ended fund companies

Part IVA sits next door and deals with open-ended fund companies, a corporate fund structure introduced to give Hong Kong an alternative to the unit trust. For Paper 1 you need to recognise the name, know it is a fund vehicle regulated under the Ordinance, and know that a code governs its operation. That is the whole examinable footprint, and it is a good example of a subject where reading further is pure cost.

How Part IV is examined

Three recurring shapes. Is this offer caught by the authorisation requirement. Which authorisation is in question, the document or the scheme. And what does authorisation actually signify, where the wrong answers dress it up as approval or endorsement.

The opinion: Part IV is worth one pass, not three. It is one of the eleven Topic 3 headings and it reliably contributes something, but the reasoning is shallow and there are no numbers to drill. Read it once, do a handful of items, move on. Compare that with Part V or the enforcement chain, where a second pass genuinely changes your accuracy.

The concession: for anyone whose job involves distributing funds or structuring offers, this is the most professionally useful Part in the whole of Topic 3, and treating it as a single-pass topic would be terrible career advice. The exam and the job diverge here more than almost anywhere else on the paper. We are giving exam advice.

The short version

  1. Offering investments to the Hong Kong public requires SFC authorisation before issue.
  2. The regime catches substance, not just formal prospectuses.
  3. Document authorisation and scheme authorisation are different decisions.
  4. Offers confined to professional investors fall outside the public offer regime.
  5. Authorisation says the requirements are met. It says nothing about merit.

For where Part IV sits among the other Parts, see the structure of the SFO, and for the broader topic, Topic 3 of the Paper 1 syllabus.

Common questions

What does Part IV of the SFO require?

That an advertisement, invitation or document containing an invitation to the Hong Kong public to acquire securities or interests in a collective investment scheme be authorised by the SFC before it is issued. The requirement applies to substance rather than to a particular document format.

Does SFC authorisation mean a fund is recommended?

No. Authorisation means the offering document, or the scheme, meets the SFC's requirements for a public offer. It carries no view on the merits, the pricing, or the likely performance of the investment, and it is not a guarantee. The SFC has no objective to protect investors against loss.

What is the professional investor exemption?

An offer confined to professional investors is not an offer to the public and therefore does not engage the Part IV authorisation regime. It is the practically important exemption, and it explains why a great deal of institutional business in Hong Kong proceeds on documents the SFC has never seen.

What is the difference between authorising a scheme and authorising an offering document?

They are separate decisions under separate provisions. Authorising an offering document concerns the material being issued to investors. Authorising a collective investment scheme concerns the scheme itself. Exam items are frequently built by describing one and offering the other as the answer.

What is an open-ended fund company?

A corporate fund vehicle regulated under the Ordinance, dealt with in Part IVA and governed by a dedicated code. For Paper 1 purposes you need to recognise the name and know it is a fund structure regulated under the Ordinance. The operational detail is not examinable at this level.
