Master-feeder structures are one of the most common architectures for Cayman Islands hedge funds and increasingly for certain private funds. They allow investors from different jurisdictions — onshore and offshore, taxable and tax-exempt — to invest in a unified investment strategy through separate feeder vehicles, all feeding into a single master fund that does the actual investing.
From a CIMA compliance perspective, this creates a layered set of FAR obligations that can be confusing. Different rules apply depending on which entity in the structure is regulated, which is not, and how the structure is organised. This guide sets out the rules clearly.
The Basic Structure and Regulatory Status
A typical Cayman master-feeder structure involves:
- A Cayman master fund — holds investments and conducts all trading
- A Cayman offshore feeder fund — accepts subscriptions from non-US investors
- A US or other onshore feeder — accepts subscriptions from US taxable investors (often a Delaware LP)
- Possibly a Cayman onshore feeder — accepts subscriptions from US tax-exempt investors
For CIMA regulatory purposes, the relevant question is which of these entities is registered under the Mutual Funds Act or the Private Funds Act.
Which Entities Must Register with CIMA?
The Cayman master fund must register with CIMA as a regulated mutual fund under the Mutual Funds Act if it has one or more regulated Cayman feeder funds investing through it.
The Cayman offshore feeder fund must register with CIMA as a mutual fund in its own right — typically as a registered mutual fund requiring a minimum subscription of US$100,000 or listed on a recognised stock exchange.
The US or other onshore feeder is not a Cayman entity and therefore does not register with CIMA. It is entirely outside the Cayman regulatory perimeter.
Each CIMA-registered entity — the master fund and each Cayman feeder — has its own, independent FAR filing obligation. They are not consolidated into a single filing. Each fund files its own FAR and pays its own filing fee.
The Master Fund FAR: What's Different
The master fund's FAR has some specific characteristics that differ from a typical standalone fund:
Investor information reflects feeder funds, not end investors. The master fund's investors are its feeder funds — not the underlying individual or institutional investors who subscribed through the feeders. The FAR investor section for a master fund therefore reflects the feeder funds as its investor base, categorised by the type of feeder (e.g. Cayman offshore, US onshore).
Investment strategy and financial data relate to the master's activities. All trading, positions, and financial information in the master fund's FAR reflects the master-level portfolio, not the consolidated position of the whole structure.
Related Fund Entity disclosure. The master fund's FAR must identify its feeder funds as related entities. Similarly, each feeder's FAR must identify the master fund as a related entity.
The Feeder Fund FAR: What's Different
Each Cayman feeder fund files its own FAR independently. Key points:
Financial data reflects the feeder's interest in the master. The feeder fund's primary asset is its investment in the master fund. The FAR financial data must reflect this — typically showing the feeder's NAV as its principal asset, with the corresponding financial statement data drawn from the feeder's audited accounts.
The feeder's audit and the master's audit are separate. Each regulated entity must be audited by a CIMA-approved Cayman auditor. In practice, the same audit firm often audits both the master and the feeders, but they are separate audit engagements producing separate audit reports.
The feeder's auditor submits the feeder's FAR. For mutual funds (which master-feeder structures predominantly are), only the CIMA-approved local auditor may submit the FAR. Each fund's auditor handles that entity's submission independently.
A Common Mistake: Treating the Structure as One Filing Unit
The most frequent error in master-feeder FAR compliance is treating the entire structure as a single filing unit — either filing only the master's FAR and assuming the feeders are covered, or vice versa. Each registered Cayman entity is a distinct regulated fund with its own obligations. Missing the feeder's FAR while filing the master's (or vice versa) leaves individual entities non-compliant.
Non-Cayman Feeder Funds
Where the structure includes a non-Cayman feeder (such as a Cayman-managed Delaware LP feeder), that entity does not register with CIMA and has no Cayman FAR obligation. However, the Cayman master fund must still disclose the existence of related non-Cayman feeder funds in the appropriate section of its FAR — specifically in the investor information section, where the non-Cayman feeder would appear as an investor of the master.
Practical Checklist for Master-Feeder Operators
Before each June 30 deadline:
- Confirm the CIMA registration status of every entity in the structure
- Ensure a separate FAR preparation workflow exists for each registered entity
- Confirm each registered entity's auditor has been instructed to submit that entity's FAR
- Verify that Related Fund Entity cross-references are consistent across all filings
- Validate each FAR form before submission — errors in one entity's form can create inconsistencies flagged in another's
