KYC for Fund of Funds and Nominee Investors

When a subscription comes from another fund, a nominee company or a platform, the name on the register is not the person whose money it is. This guide sets out the four routes a fund manager or administrator can take, what Hong Kong, Singapore, Cayman, UK, EU and US rules say about each, the contents of a usable AML confirmation, and worked scenarios.

Quick Answer

You always need to know who the fund of funds or nominee is; the question is whether you must also look through it. Where a regime requires look-through, it can be avoided only where a specific rule allows it. In Hong Kong, SDD is available for an FI as defined in the AMLO that holds through a nominee company (SFC Guideline 4.8.6) and for an investment vehicle whose investors are covered by a qualifying institution (4.8.9 to 4.8.11); otherwise the firm must identify and take reasonable measures to verify the investors, possibly relying on a written representation depending on risk (4.8.12). In Singapore, paragraph 6.16 of MAS Notice SFA04-N02 removes the beneficial-owner inquiry for supervised financial institutions and investment vehicles with supervised managers, and the Guidelines say the firm should obtain a distributor's confirmation. In the Cayman Islands, regulation 24 of the AMLRs allows an eligible nominee to give a written assurance, but the fund stays liable if it fails. In the US, FinCEN's rule, effective 1 January 2028, takes a risk-based view of intermediaries. In Hong Kong and Singapore, doubts or suspicion remove the shortcut; in the Cayman Islands, suspicion does.

Fund of funds and nominee holdings are a normal part of fund distribution, and in our experience institutional investors use them for scale, custody and confidentiality. They also reduce the fund's view of the person behind the money, and nominee shareholders appear in the higher-risk factor lists of the UK and EU rules. The compliance task is to decide, investor by investor, how much of that gap you may lawfully accept, and to keep evidence for the decision.

This article is written for compliance and operations teams at fund managers, administrators and transfer agents. It builds on our entries on the look-through approach, omnibus accounts and simplified due diligence, and on the wider LP onboarding checklist. It cites the current texts as read on 5 November 2026 and is general information, not legal advice.

Four Routes for an Intermediated Investor

Almost every decision reduces to one of these four routes. Regimes differ on which are available and on what conditions, so the choice has to be recorded against a specific provision.

Route	What the fund does	Typical fit	Main risk
Full look-through	Identifies and verifies the underlying investors or beneficial owners itself	Small private vehicles, family structures, unregulated nominees, higher-risk intermediaries	Commercial resistance; data-protection and confidentiality limits
Exemption or SDD on the intermediary	Performs CDD on the regulated intermediary and documents why the beneficial-owner measure does not apply	A supervised bank, broker or nominee; a fund with a supervised manager	Status assumed, not checked; exemption applied where the law does not extend it
Written assurance or reliance	Obtains a written confirmation that the intermediary has done CDD and will provide records on request	Eligible nominees and introducers under Cayman regs 24 and 25, and reliance provisions elsewhere	The fund stays liable if the intermediary fails; copies never tested
Representation about the investors	Accepts a written statement of who the investors are, or that there is no such investor	Hong Kong 4.8.12, where risk factors allow it	Accepted without assessing the 4.8.12 risk factors

Hong Kong: Nominee Companies and Investment Vehicles

The nominee route (paragraph 4.8.6). A financial institution may apply SDD to a customer that is an FI as defined in the AMLO and that opens an account in the name of a nominee company "for holding fund units on behalf of" that FI or its underlying customers, provided the second FI has conducted CDD on those underlying customers and is authorised to operate the account "as evidenced by contractual document or agreement". The same paragraph covers an account in the name of an investment vehicle where the FI acts as its service provider and the underlying investors have no control over the management of its assets, subject to CDD on the vehicle and the same contractual authority.
The investment vehicle route (4.8.9 to 4.8.11). SDD is available if the FI can ascertain that the person responsible for measures similar to CDD "in relation to all the investors" falls within the categories in section 4(3)(d) of Schedule 2 to the AMLO. Where permitted by law, a vehicle may appoint a manager, trustee, administrator, transfer agent, registrar or custodian to perform CDD. The FI must be satisfied that the vehicle has ensured reliable systems and controls to conduct CDD on the underlying investors under requirements similar to Schedule 2.
When neither qualifies (4.8.12). The FI "must identify and take reasonable measures to verify the identity of any investor" under the beneficial-owner requirements. It may consider relying on a written representation from the vehicle or appointed institution stating, "to its actual knowledge", who those investors are or that there is no such investor. Whether that is appropriate depends on factors such as "whether the investment vehicle is being operated for a small, specific group of persons". An accepted representation must be documented, retained and periodically reviewed.
Nominee shareholders (4.12.4). For a customer with nominee shareholders in its ownership structure, the FI should obtain satisfactory evidence of the identities of the nominees, of the persons on whose behalf they act, and of the arrangements in place. See our guide to SFC AML requirements for asset managers.

Singapore: The Definition of Customer and Paragraph 6.16

Investors are customers, with exclusions. Under MAS Notice SFA04-N02 a customer includes a person "who has invested or who invests into an investment vehicle to which the CMI provides the regulated activity of fund management". That excludes an investment vehicle that is a listed entity under paragraph 6.16(a) or (b), one whose interests are distributed by a financial institution described in 6.16(c) or (d), and one whose primary manager is another financial institution supervised to FATF standards.
No beneficial-owner inquiry for certain customers (6.16). No inquiry is required for entities listed on the Singapore Exchange, or on a foreign exchange subject to disclosure and transparency requirements, financial institutions in Appendix 1, foreign financial institutions supervised to FATF standards, and investment vehicles whose managers are such institutions, unless the CMI has doubts about the veracity of the CDD information or suspects ML/TF. The basis must be documented for the foreign financial-institution limbs, 6.16(d) and (e)(ii) (6.17). Footnote 6 keeps the inquiry where the CMI itself is the vehicle's primary manager, unless a qualifying FI distributes the interests.
Portfolio managers (Guidelines). Where a primary manager may be reluctant, for commercial reasons, to reveal investors, the CMI "should evaluate the risks arising from each case and determine the appropriate CDD measures to take". If the fund meets a 6.16 criterion, the CMI may use that exemption; if not, it applies appropriate CDD on the underlying investors, and SCDD only if section 7 is met.
Distributors and omnibus accounts (Guidelines). MAS accepts that the CMI "typically has no visibility of the underlying investors" where a distributor uses omnibus accounts in its own name. Where those investors are customers of a supervised FI, the CMI "should obtain confirmation from the distributor that the latter would be responsible for carrying out AML/CFT checks on the underlying investors". See MAS Notice SFA04-N02 explained.

Cayman Islands: Regulation 24 and the Written Assurance

The rule. Regulation 24 of the Anti-Money Laundering Regulations (2025 Revision) applies where an applicant "is or appears to be acting as an agent or nominee for a principal". Verification is required unless the applicant falls within regulation 22(1)(d) and gives a written assurance. These simplified measures apply only where the firm has assessed a low level of risk, consistent with the national risk assessment or the supervisor's findings (reg 21).
Who is eligible. Regulation 22(1)(d) covers persons required to comply with regulation 5 and majority-owned subsidiaries of the relevant financial business; government bodies in a country the firm has assessed as low risk; businesses subject to an overseas regulatory authority and based or incorporated in, or formed under the law of, such a country (and their majority-owned subsidiaries); listed companies subject to adequate beneficial-ownership disclosure (and their majority-owned subsidiaries); and certain pension funds. The basis must be evidenced in writing (reg 22(2)).
What the assurance must confirm (reg 24(2)(b)). That the applicant has identified and verified the principal and any beneficial owner under procedures it maintains; the nature and intended purpose of the relationship; that it has identified the principal's source of funds; and that it will make copies of identification and verification data available on request and without delay.
Liability stays. A person relying on the assurance "is liable for any failure" of the applicant to obtain and record satisfactory evidence or to make it available on request without delay (reg 24(3)). CIMA's Guidance Notes repeat this (Part II, s.5 E.6).
Investors that are funds. Part VI of the Guidance Notes says an investor that is a fund domiciled outside, but administered in, a country the firm assesses as low risk may fall within an SDD scenario, and that evidence may also be satisfactory if the investor's administrator is subject to AML oversight in its home country and confirms in writing that it has obtained and maintains customer verification evidence under the procedures of that low-risk country (F.6, F.7). See Cayman AML rules for funds.

United Kingdom and European Union

UK. Where the customer is beneficially owned by another person, MLR 2017 reg 28(4) requires the firm to identify the beneficial owner and take reasonable measures to verify identity, and to understand the ownership and control structure of a beneficial owner that is a legal person or arrangement. Reg 33(6)(a)(iv) lists "a company that has nominee shareholders or shares in bearer form" as a customer risk factor. Reliance under reg 39 leaves the firm liable, and the firm must obtain the CDD information immediately and arrange to get copies of the data immediately on request.
EU from 10 July 2027. Article 61 of Regulation (EU) 2024/1624 sets a harmonised test for collective investment undertakings: the beneficial owners are the natural persons who hold directly or indirectly 25% or more of the units, or who have the ability to define or influence the investment policy, or who control the activities by other means. Article 66 requires nominee shareholders and nominee directors of a legal entity to keep information on their nominator and its beneficial owners and to disclose it and their status to the entity, which reports it to obliged entities applying CDD. Article 53(4)(c) treats nominee arrangements as a possible means of control, and Annex III lists corporate entities with nominee shareholders as a higher-risk factor.
Ireland today. The Central Bank's 2021 funds bulletin calls distributor and sub-distributor relationships "a common feature of this sector" that increases ML/TF risk exposure, and it found that firms did not sufficiently demonstrate a comprehensive review of such risks in their business risk assessments.

United States: Risk-Based, With Limits on What Is Required

Status. FinCEN's investment adviser rule (89 FR 72156) takes effect on 1 January 2028 under the delay rule at 91 FR 36, and FinCEN has said it will use the delay to review the rule.
Who the customer is. FinCEN notes that in the private fund context "the adviser's customer is typically the private fund itself, and not underlying investors" (fn 45), though it adds that in many cases the adviser has a relationship with, and information about, those investors, and that for section 314(a) requests an adviser would generally respond for the fund, not its underlying investors.
What FinCEN expects on intermediaries. FinCEN acknowledges diligence on intermediaries representing underlying investors. "In some instances, depending on the risk", the adviser may determine that it does not need additional diligence on investors represented by intermediaries; "in other instances" of higher risk it may need more about the underlying investors to develop a customer baseline for suspicious activity reporting (89 FR 72196). Advisers "should collect sufficient information such that they are able to detect and report suspicious activity" (89 FR 72195). FinCEN also expects a primary adviser to assess the risks presented by a private fund's investors, and an adviser that tries and fails to obtain identifying information may treat the fund as higher risk (89 FR 72191).
Banks and brokers treat pooled vehicles differently. Under 31 CFR 1010.230, which binds covered financial institutions, a pooled investment vehicle operated or advised by an excluded financial institution is not a legal entity customer (e)(2)(xi); one operated or advised by a non-excluded institution is subject only to the control prong (e)(3)(i).
Separate tests that can require a view through the holder. Section 3(c)(1)(A) of the Investment Company Act counts the holders of an investing company that owns 10% or more of the fund's voting securities and is, or but for 3(c)(1) or 3(c)(7) would be, an investment company. The final rule's scope test for foreign-located advisers says they must "look through" nominee and similar arrangements to determine whether a private fund has a US-person investor. OFAC's 50 Percent Rule aggregates indirect ownership by blocked persons. See our FinCEN adviser rule guide.

A Step-by-Step Procedure

Classify the holder

Is the subscriber acting for itself, for a principal, or for many clients? A fund of funds generally invests for its own account as a vehicle with its own investors; a nominee holds for someone else; a platform or distributor may use an omnibus account. Ask directly in the subscription form, and do not infer it from the name.

Do CDD on the holder itself

Whichever route follows, the intermediary is your customer or applicant. As good practice, verify its existence and its signatories even where a rule such as Cayman reg 22 removes formal verification, understand the purpose of the relationship and screen it. No route removes the need to know who you are dealing with.

Test its regulatory status from a primary source

Check the regulator's register, record the licence and date, and assess whether the country meets the test. For institutions under s.4(3)(a) and (b), the SFC says it will generally be sufficient to verify that the institution is on the list of licensed and supervised FIs in the jurisdiction concerned (4.8.7). For a fund of funds, test the entity the regime looks at: in Hong Kong the person responsible for CDD on all its investors, in Singapore its managers, and in the Cayman Islands the fund itself, or Part VI F.6 and F.7 if it is administered in a country you assess as low risk.

Choose the route and write it down

Record which provision you are relying on, why it applies, and who approved it. Cayman reg 22(2) and, for its foreign financial-institution limbs, MAS 6.17 require the basis to be recorded. If no route applies, look through to the underlying investors or decline the subscription.

Collect the confirmation

Use one standard AML confirmation (the contents are listed below) signed by a named person at the intermediary. Refresh it on a schedule, and on any change of ownership, regulator or manager.

Test access

Where the regime or your risk rating relies on an intermediary's records, request a sample. A right to copies that has never been used is weak evidence that the arrangement works, and under Cayman reg 24(3) the failure is yours.

Monitor the account

A single holder can hide changes beneath it. Monitor subscription and redemption patterns against the expected profile, and ask for information when activity does not fit. CIMA asks that investors be periodically screened and reviewed by risk rating.

What an AML Confirmation Should Contain

No regulator prescribes one global form, so build yours from the strictest elements above. We suggest a confirmation states:

The legal name and capacity of the intermediary (nominee, manager, administrator, distributor) and its regulator and licence number
A confirmation that it has identified and verified its principals or investors and any beneficial owners under procedures it maintains, and the regime those procedures follow
The nature and intended purpose of the relationship, and a confirmation that the source of funds of the principal has been identified (Cayman reg 24(2)(b)(ii) and (iii))
A sanctions and PEP screening statement, with the lists and frequency used
An undertaking to supply copies of identification and verification data on request and without delay, and to keep them for the statutory period
A statement, to its actual knowledge, of the identities of investors who must be identified under the applicable beneficial-owner test, or that there are none (compare Hong Kong 4.8.12)
An undertaking to notify changes in regulatory status, ownership or control, and any principal that becomes sanctioned
Date, signatory, title, and the next review date

A Cayman reg 24 assurance must cover its four statutory confirmations. Adapt the remainder to the intermediary's regime, and have counsel review the template.

Worked Scenarios

The scenarios are illustrative. The route depends on the actual facts and on the regime that binds your fund and manager.

Scenario	Likely route	What to keep
A Hong Kong licensed bank subscribes to a Hong Kong-managed fund through its nominee company for its private clients	Hong Kong 4.8.6(a): SDD on the bank, if it has done CDD on those clients and is contractually authorised to operate the account	Licence check, the contract, proof of the nominee link
A fund of funds run by a supervised European manager subscribes to a Cayman feeder	Reg 22(1)(d)(iii) only if the investing fund itself acts in the course of a business regulated by an overseas regulatory authority and is based in, or incorporated or formed under the law of, a country you assess as low risk, with reg 22(1)(a) to (c) and a low-risk assessment under reg 21 met. If it is administered in such a country, consider Part VI F.6, or F.7 evidence from its administrator	Written basis under reg 22(2), register evidence, confirmation letter, ownership statement identifying any natural person at 10% or more (AMLRs reg 2)
A Singapore licensed manager distributes through a regional bank using omnibus accounts	MAS Guidelines: confirmation from the distributor that it is responsible for AML/CFT checks on the underlying investors; consider SCDD on the distributor	Distribution agreement, confirmation, 6.17 basis if the distributor is foreign
A family office SPV with a professional nominee director and a nominee shareholder invests in a US-managed 3(c)(7) fund	The FinCEN rule sets no exemption to test: diligence on this investor is risk-based, and an opaque nominee structure points to obtaining the principals' identities so the adviser can monitor and report. Separately, if the SPV was formed for the specific purpose of investing, each beneficial owner must be a qualified purchaser (17 CFR 270.2a51-3(a))	Nominee agreement, identity of nominator, structure chart, source of wealth
An unregulated private fund of funds with six investors says it "does its own KYC"	Not a qualifying person; in Hong Kong, 4.8.12 applies. The Guideline names operation for a small, specific group of persons as a risk factor; in our view a bare statement is weak here	Identity of each relevant investor, or a declined subscription

Common Failure Points

Treating "regulated" as a yes/no answer. The answer depends on the regime: Hong Kong looks at who performs CDD on the investors, Singapore at the managers, and the Cayman Islands at the applicant itself under reg 22, with Part VI F.6 and F.7 looking to its administration.
Accepting a comfort letter with no regime behind it. A letter saying "we comply with applicable AML laws" does not answer who was verified, under what procedures, or whether copies are available.
Stale confirmations. A letter from the first closing remains on file six years later, after the intermediary has changed ownership or regulator. Hong Kong expects accepted representations to be subject to periodic review.
Screening only the holder of record. If you have no view of underlying investors, record who screens them, and use the confirmation to say so.
Ignoring concentration. A nominee with one large client is closer to that client's own account than to a diversified platform. Ask for concentration information, and consider whether any principal crosses your threshold.
Assuming one answer per structure. A master-feeder structure may need different answers at each layer: see our master-feeder structure entry and the look-through approach.

How One Constellation Supports Intermediated Investors

One Constellation gives fund managers, administrators and transfer agents an investor onboarding portal that records each investor's capacity (own account, nominee, fund of funds, distributor), KYB and beneficial-ownership tracing across the structure, sanctions, PEP and adverse-media screening at onboarding and on a periodic basis, risk rating with the chosen route and approver on file, transaction monitoring of subscriptions and redemptions, and case management with STR and SAR workflows. Confirmation letters and their review dates sit with the investor record, so that a stale assurance is visible. See transfer agencies and fund managers.

Frequently Asked Questions

Do I have to look through a fund of funds to its investors?

Not always. In Hong Kong, SDD is available if the person responsible for CDD on all the investors falls within a qualifying category (SFC Guideline 4.8.9 to 4.8.11). In Singapore, no beneficial-owner inquiry is needed if the fund's managers are qualifying financial institutions (MAS Notice SFA04-N02 paragraph 6.16(e), subject to footnote 6). In the Cayman Islands an investor that is a fund may fall within an SDD scenario if administered in a country the firm assesses as low risk. If no qualifying person exists, the firm must identify and take reasonable measures to verify the investors or decline, unless the regime permits a written representation. Under those Hong Kong and Singapore provisions, doubts or suspicion remove the exemption.

What is a nominee investor in a fund?

In general usage, a nominee investor is a person or company registered as the holder of fund interests on behalf of someone else, called the principal or beneficial owner. Banks, brokers and platforms commonly use nominee companies for their clients. The fund's register shows the nominee, and the identity of the person behind it is held by the nominee.

Can a fund rely on a nominee's KYC?

Only under a provision that allows it. Cayman regulation 24 permits it where the nominee falls within regulation 22(1)(d) and gives a written assurance covering verification, purpose, source of funds and access to records; the fund remains liable if the nominee fails. Hong Kong allows SDD on a financial institution using a nominee company under conditions in paragraph 4.8.6. The UK reg 39 reliance route also leaves liability with the relying firm.

What is the difference between a nominee account and an omnibus account?

In general usage, a nominee account is held by one person on behalf of one or more beneficial owners, and an omnibus account pools many clients in one position on the register. MAS's Guidelines describe distributors using omnibus accounts in their own name, and say the firm should obtain a distributor's confirmation that it is responsible for AML/CFT checks where the underlying investors are customers of a supervised financial institution.

What should an AML comfort letter from an intermediary say?

It should name the intermediary, its capacity and its regulator; confirm that it has identified and verified its principals under procedures it maintains; state the nature and purpose of the relationship and that source of funds has been identified; describe screening; undertake to provide copies of identification data on request and without delay; state, to its actual knowledge, any investor who must be identified under the applicable beneficial-owner test, or that there is none; and give a date and signatory. It should be reviewed periodically and on any change.

Does the FinCEN rule require advisers to look through to fund investors?

Not categorically. FinCEN says the adviser's customer is typically the private fund itself and that advisers are not at this time categorically required to collect beneficial ownership information for private funds. Depending on risk, an adviser may decide it needs no more on investors represented by intermediaries, or may need more to set a baseline for suspicious activity reporting. The rule takes effect on 1 January 2028. OFAC's sanctions rules and section 3(c)(1) counting are separate tests that can require a view of underlying holders.
