The Cayman Limited Investor Fund: Section 4(4) Registration With No Minimum Subscription

A Cayman limited investor fund is a mutual fund registered with CIMA under section 4(4)(a) of the Mutual Funds Act (2025 Revision). It is the one route in the Act with no statutory minimum subscription, available only where the equity interests are held by not more than fifteen investors, a majority of whom can appoint or remove the operator. For a manager whose seed investors will commit less than the CI$80,000 minimum in section 4(3), it is often the difference between launching and not launching. It is not a lighter regime: registration, the annual audit, the Fund Annual Return and the anti-money laundering framework apply in full. This article sets out the statutory test, the fees, the sixteenth investor and the alternatives.

"We see the limited investor fund misread in both directions. Some managers assume it is a private arrangement that sits outside CIMA. It does not; it has been a registered category since 2020, and the audit applies with no small-fund relief. Others dismiss it because of the fifteen-investor ceiling without doing the arithmetic on their actual first-year investor list. Our view is that it is a precise tool for a precise problem: a strategy with committed backers who will not each write a US$100,000 ticket. Used for that, with the conversion to section 4(3) planned from day one, it works well." David Lloyd, Chief Executive Officer at CV5 Capital

Executive Summary

Section 4(4)(a) gives a small, investor-controlled open-ended fund a registration route without the CI$80,000 per-investor minimum. It changes who can invest, not what the fund must do.

• Both statutory limbs must be satisfied: not more than fifteen investors, and a majority of them in number able to appoint or remove the operator.
• The fund must register with CIMA before carrying on business, file a certified constitutional extract, and pay the annual fee of CI$4,125.
• Section 8 requires an annual audit by a CIMA-approved auditor, filed within six months of year end with the Fund Annual Return.
• A master fund cannot use the route, because section 4(4A) excludes it expressly.
• A sixteenth investor takes the fund outside the category, and conversion to section 4(3) requires every investor to meet the minimum or be redeemed.
• AML officers, FATCA and CRS, economic substance, beneficial ownership and director registration all apply unchanged.

Why the Section 4(3) Minimum Is the Constraint

The standard registration route for an open-ended Cayman fund is section 4(3). Section 4(3)(a)(i) requires that the minimum aggregate equity interest purchasable by a prospective investor is eighty thousand dollars, or its equivalent in any other currency. At CIMA's published conversion basis of US$1.21951 to CI$1, that is US$97,561, which CIMA itself and the market round to US$100,000. The only alternative within section 4(3) is a listing on a stock exchange specified by CIMA in the Gazette. Section 4(1), covering licensed and administered funds, also carries no minimum but suits larger or retail-facing structures.

That figure is a per-investor floor, not a fund-size floor, and it binds at the point of entry. A manager whose backers are former colleagues or a small professional network will often find that several intend to commit US$25,000 or US$50,000. A section 4(3) fund cannot accept any of them, and that is where many launches stall. CV5 has set out the wider question of how much AUM a hedge fund needs before launch. This article addresses the narrower one: what to do when the constraint is the size of each ticket rather than the total.

What Section 4(4)(a) Actually Says

Section 4(4)(a) provides that a mutual fund may carry on business in or from the Islands without complying with subsection (1). The condition is that the equity interests are held by not more than fifteen investors, a majority of whom are capable of appointing or removing the operator of the fund. Unless CIMA grants an exemption, four further conditions attach. A certified extract of the constitutional documents must be filed, specifying that a majority of the investors in number can appoint or remove the operator. The prescribed form must be filed, the fund registered with CIMA, and the prescribed annual registration fee paid.

Three definitions in section 2 determine how the test applies. An investor is the legal holder of record of an equity interest, and the definition expressly excludes a promoter or operator. The operator is a director of a company, a general partner of a partnership, or a trustee of a unit trust. An equity interest carries a right to participate in profits and is redeemable at the option of the investor, so non-participating, non-redeemable management shares fall outside the count.

Section 4(4A) provides that subsection (4)(a) does not apply to a master fund, and CIMA's published FAQ confirms the carve-out. Section 4(10) allows a fund within subsections (3) or (4) to comply with subsection (1) instead. The governance limb is measured by number, not by value: a single anchor holding ninety per cent of the capital does not satisfy it.

What the route is not

The limited investor fund is a registration category, not an exemption. Before the Mutual Funds (Amendment) Act 2020 took effect on 7 February 2020, funds with fifteen or fewer investors sat outside CIMA registration; the amendment brought them inside. The Act now defines a regulated mutual fund to include a fund complying with section 4(4)(a), and every obligation attached to that status follows. Section 4(2) makes the operator responsible for compliance, with a fine of one hundred thousand dollars on conviction.

Registration, Fees, Audit and the Fund Annual Return

Registration must be in place before the fund carries on business; the Act contains no grace period. CIMA's published FAQ lists the application package for a section 4(4) fund. It comprises application forms APP-101-78 and APP-101-79, the certificate of incorporation or formation, and the offering memorandum or summary of terms. It also requires confirmation from the constitutional documents or a resolution that a majority of investors can appoint or remove the operator, and the auditor's letter of consent if available.

Figures current as at 5 September 2026. The fees below are prescribed by the Mutual Funds (Fees) Regulations (2026 Revision) and published on CIMA's fee schedule updated 1 January 2026. They are statutory amounts, not a launch budget; the commercial stack is set out in what a Cayman hedge fund actually costs to launch and run.

The annual fee is identical to the fee for a licensed, administered or registered fund. Cost is not the reason to choose the route, and anyone presenting it as a cheaper registration is misreading the schedule. The choice turns on which statutory conditions the fund can satisfy.

The audit and the FAR apply without small-fund relief

Section 8(1) requires a regulated mutual fund to have its accounts audited annually by an auditor approved by CIMA. Section 8(2) requires the audited accounts to reach CIMA within six months of the financial year end, or within such extension as CIMA allows. CIMA's general industry notice of 26 November 2020 confirmed that a limited investor fund is subject to the annual audit, and that the first audit period may on application run to eighteen months from registration. Section 8(4) gives CIMA power to exempt a fund from the audit, but that is a discretionary waiver, not a feature of the category.

The Mutual Funds (Annual Returns) Regulations (2026 Revision) require complete returns for each financial year, and for each sub-fund, within the same six-month window. The return goes through the auditor, and the operator is responsible for compliance. The particulars cover the investment manager, the administrator, the NAV calculation agent, the custodian and the operating structure. CV5 has described the process in what the Fund Annual Return requires and when. A manager choosing section 4(4) to reduce reporting will find nothing has been reduced.

How the Limited Investor Fund Compares With the Alternatives

The Mutual Funds Act categories and the closed-ended Private Funds Act regime are distinguished by their entry conditions, not by the obligations that follow. Which Act applies turns on whether investors can compel redemption, a question CV5 addresses in whether the Mutual Funds Act or the Private Funds Act governs a fund. The comparison below is confined to the entry conditions that most often decide the question for an emerging manager.

The limited investor fund is the only open-ended route that combines no minimum subscription with no requirement for a licence or a licensed administrator's principal office. The price is the fifteen-investor ceiling and the governance limb, and both are absolute. A fund of one satisfies both limbs by definition, and CV5 has addressed that structure in structuring a single-investor Cayman fund.

The Sixteenth Investor and Conversion to Section 4(3)

The Act contains no cure period. On the day a sixteenth investor becomes the legal holder of record of an equity interest, the fund no longer satisfies section 4(4)(a), and section 4(2) places the consequence on the operator. The same result follows if the articles are amended so that a majority can no longer remove the operator, or if a transfer changes the arithmetic. The register of members and the transfer provisions are the control points.

CIMA's published FAQ sets out what conversion involves. A fund moving from section 4(4) to section 4(3) must comply with the minimum initial investment requirement and demonstrate it by affidavit. Any investor whose initial investment was below the minimum must increase it or be redeemed out before the fund re-registers, unless the current holding already meets the minimum. The re-registration package includes the relevant fund form, the offering memorandum, confirmation that annual fees, FAR fees and audited accounts are up to date, and the CI$300 application fee. CIMA recognises the date on which a complete application is received.

Conversion in the other direction is also available. CIMA lists the requirements as an affidavit that the fund has fifteen or fewer investors, with evidence that a majority can remove the operator. The same ceiling then applies.

The Arithmetic for a Manager Whose Backers Are Below the Minimum

The route changes the entry condition, not the economics. Section 4(4) removes the per-investor floor, so the minimum launch size becomes whatever the backers will actually commit. The fixed cost of a regulated Cayman fund is unaffected: the annual fee is the same, the audit applies, and the administrator, directors, registered office, AML officers and insurance are still required. Break-even therefore does not move.

What moves is whether the fund can be formed at all. The table below is illustrative only. It makes no statement about any fund's actual costs or terms.

The route is most valuable where the committed backers are comfortably inside fifteen and the ticket sizes are the binding problem. Where every backer can meet the minimum, it accepts a ceiling in exchange for nothing. Count heads and count tickets before choosing.

How a Limited Investor Fund Sits on a Platform

The registration category attaches to the mutual fund, and the mutual fund is the legal entity that issues the equity interests. A segregated portfolio is not a legal person separate from the company. Section 4(4)(a) is expressed by reference to the equity interests of the mutual fund, and an investor is the holder of an equity interest in the mutual fund. On the plain reading of the Act, the fifteen-investor test applies to the registered entity as a whole, not portfolio by portfolio.

The consequence for a multi-manager platform is direct. Where the platform company is registered under section 4(3), the CI$80,000 minimum applies to every investor in every portfolio, because that is the condition on which the entity is registered. A section 4(4)(a) portfolio cannot be carved out of a section 4(3) company.

A manager whose backers are below the minimum therefore has two answers on a platform. The first is a separate entity registered under section 4(4)(a) in its own right, with the platform supplying governance, administration, banking, audit coordination and reporting around it. The second is to bring the investor list up to the minimum and use a portfolio of the section 4(3) company, the standard route described in how multiple funds are launched under one regulated platform.

CV5 Capital operates CV5 SPC for traditional strategies and CV5 Digital SPC for digital asset strategies, providing the regulated platform, the governance framework, the service provider architecture and the establishment process. The appointed investment manager runs the strategy, selects the investments and is responsible for the returns. Where a limited investor structure is the right answer, the platform's value lies in supplying the operating stack that section 4(4) does not remove, with the conversion to section 4(3) built in from the start.

The Obligations That Do Not Change

Because a section 4(4)(a) fund is a regulated mutual fund and a Cayman legal entity, the surrounding obligations apply in full. None is relaxed by the registration section. Each is a recurring task to budget for from the first year.

• Anti-money laundering. The fund must appoint an anti-money laundering compliance officer, a money laundering reporting officer and a deputy under the Anti-Money Laundering Regulations, and CIMA's FAQ lists their omission among the causes of delayed applications.
• FATCA and CRS. A Cayman fund is ordinarily a reporting financial institution. The DITC's advisory of 31 March 2026 set CRS and FATCA reporting at 31 July 2026 and the CRS Compliance Form at 15 September 2026.
• Economic substance. An investment fund is not a relevant entity under the International Tax Co-operation (Economic Substance) Act, but the annual economic substance notification is still filed, confirming the entity's status as an investment fund.
• Beneficial ownership. The Beneficial Ownership Transparency Act 2023 came into force on 31 July 2024. A fund registered under the Mutual Funds Act is not exempt. It may instead name a contact person, a licensed fund administrator or another person licensed or registered with CIMA, able to produce the information within twenty-four hours.
• Directors. Where the fund is a company, its directors fall within the Directors Registration and Licensing Act, and CIMA's corporate governance rules apply to the board.
• Offering document currency. Under section 4(8), a material change must be reflected in an amended filing within twenty-one days of the operator becoming aware of it.

The route removes the ticket-size floor and nothing else. Every institutional obligation, and the cost of discharging it, sits exactly where a section 4(3) fund would leave it. The complete formation framework is set out in the CV5 institutional guide to Cayman fund formation.

Common mistakes

• Treating the fifteen-investor cap as sufficient and leaving the appointment and removal right out of the articles.
• Counting the majority by capital rather than by number.
• Assuming the audit can be deferred at small scale.
• Accepting a sixteenth subscription before conversion to section 4(3) is complete.

Key Takeaways

• Count the committed backers and the size of each ticket before choosing a registration basis; section 4(4)(a) helps only where the head count stays within fifteen.
• Draft the articles so that a majority of investors in number can appoint and remove the operator, because the certified constitutional extract filed with CIMA must say so.
• Budget for the annual audit, the Fund Annual Return and the full service provider stack from year one, since the route removes none of them.
• Write the section 4(3) conversion into the subscription documents at launch, including top-up or redemption mechanics for sub-minimum investors.
• Keep the register of members and the transfer provisions under board control, because the investor count is the compliance test.
• On a platform, decide early whether the strategy needs its own section 4(4)(a) entity or can meet the minimum inside a section 4(3) company.

Frequently Asked Questions

What is a Cayman limited investor fund?

A limited investor fund is an open-ended mutual fund registered with CIMA under section 4(4)(a) of the Mutual Funds Act (2025 Revision). Its equity interests are held by not more than fifteen investors, a majority of whom in number are capable of appointing or removing the operator. It carries no statutory minimum subscription, but it is a registered and regulated mutual fund, subject to the annual audit and the Fund Annual Return.

Is there a minimum investment for a section 4(4) fund?

No. The CI$80,000 minimum aggregate equity interest in section 4(3)(a)(i) does not apply to a fund registered under section 4(4)(a). The fund may set whatever minimum its offering document specifies. The trade-off is the ceiling of fifteen investors and the requirement that a majority of them can appoint or remove the operator.

Does a limited investor fund need an audit?

Yes. Section 8 of the Mutual Funds Act requires every regulated mutual fund, including a section 4(4)(a) fund, to have its accounts audited annually by a CIMA-approved auditor and to file them within six months of the financial year end. CIMA confirmed this in a general industry notice dated 26 November 2020. Section 8(4) allows CIMA to grant an audit waiver on application, but a waiver is not automatic.

What happens if a limited investor fund gets a sixteenth investor?

The fund ceases to satisfy section 4(4)(a) and is no longer carrying on business in compliance with the Act, with the operator responsible under section 4(2). It must convert to section 4(3) before the sixteenth subscription is accepted. CIMA requires an affidavit that every investor meets the CI$80,000 minimum, and any investor below it must top up or be redeemed, followed by a complete re-registration application and the CI$300 fee.

Can a master fund register as a limited investor fund?

No. Section 4(4A) of the Mutual Funds Act provides that subsection (4)(a) does not apply to a master fund, and CIMA's FAQ confirms the carve-out. A master fund in a master-feeder structure registers under section 4(3)(a)(iii). A fund that operates as a master but does not meet the statutory definition of a master fund may be able to register under section 4(4)(a) if it satisfies the conditions.

How much does it cost to register a limited investor fund with CIMA?

The annual registration fee is CI$4,125, or US$5,030.49 at CIMA's conversion basis, with a CI$300 administrative fee on filing the application and CI$750 for each sub-fund. The Fund Annual Return carries a separate CI$300 filing fee. These are the statutory amounts under the Mutual Funds (Fees) Regulations (2026 Revision) and the CIMA fee schedule updated 1 January 2026; service provider costs are additional.
