Legal form and umbrella structures: companies, partnerships and segregated sub-funds compared

A fund's legal form is the kind of legal arrangement that holds investors' money: a company, a partnership or a contract such as a trust. An umbrella structure is one vehicle that holds several sub-funds (also called segregated portfolios or compartments), each with its own assets, liabilities and investors. Among the eight vehicles compared on this site, the Singapore VCC, Cayman SPC, Luxembourg SICAV, Irish ICAV and Hong Kong OFC are companies that can run umbrellas; the Cayman ELP and Hong Kong LPF are partnerships without separate legal personality. This page compares legal features; it does not rank vehicles.

Three families of legal form

The family drives three practical things. Documents: shareholders receive a constitution and offering document; limited partners sign a partnership agreement that typically sets commitments, drawdowns and distribution waterfalls. Governance: a company has a board with legal duties to the company; a partnership is controlled by its general partner. Classification: investors' own tax advisers may treat a company and a partnership differently at home, which can matter as much as the domicile's own tax rules.

The family does not dictate strategy on its own. A VCC can be used for "open-ended or closed-end funds" (MAS and ACRA, 2020), and Luxembourg's RAIF can take more than one legal form. But closed-end private equity and venture funds commonly use partnerships, and open-ended funds commonly use companies, because each form fits those cash-flow patterns.

Legal personality, vehicle by vehicle

Legal personality decides who signs contracts, who owns assets and who can be sued. A VCC or an SPC holds assets in its own name; an ELP or LPF holds them through the general partner. Neither approach is inherently safer: what protects investors is the combination of statute, documents, custody arrangements and the conduct of the people running the fund.

How statutory segregation works

Umbrella vehicles separate sub-funds by statute, not just by contract.

1. Singapore VCC. "The assets of one sub-fund cannot be used to discharge the liabilities of another sub-fund", and "each sub-fund must be wound up separately" (MOF note, 2018). ACRA describes each sub-fund as having separate assets and liabilities. Sub-funds of an umbrella must be registered through ACRA's VCC Portal within seven days of formation (ACRA Step 6, updated 15 June 2026).
2. Cayman SPC. Part XIV of the Companies Act, in force since 1998, provides for segregated portfolios with no statutory cap on their number (Conyers).
3. Irish ICAV. Section 35 of the ICAV Act provides that a sub-fund's liabilities "shall be discharged solely out of the assets of that sub-fund".
4. Luxembourg. Under Article 181 of the 2010 UCI Law, each compartment corresponds to a distinct part of the UCI's assets and liabilities, creditors' rights are limited to the relevant compartment unless the fund documents say otherwise, and a compartment may be liquidated separately (CSSF consolidated text). A RAIF can be an "umbrella structure with an unlimited number of ring-fenced sub-funds" (CMS). According to Dechert (August 2026), Bill No 8814, submitted on 30 July 2026, proposes extending compartments to SCS and SCSp partnerships; it was not enacted when this page was updated.
5. Hong Kong OFC. Umbrella OFCs with sub-funds are registered by the SFC, with separate fees per sub-fund. The segregation rules sit in the OFC Rules and OFC Code; confirm their scope with Hong Kong counsel.

Partnerships such as the Cayman ELP and Hong Kong LPF are typically used as standalone funds; sponsors who need several pools often form parallel partnerships instead of an umbrella.

The cross-border recognition question

Statutory segregation is clearest when the fund, its assets and its creditors are all in the domicile. Real funds rarely look like that. A Singapore VCC sub-fund may hold shares custodied in Hong Kong, trade derivatives under English-law contracts and borrow from a European bank. If a sub-fund fails, a creditor in another country may test whether the home statute's ring-fence binds a foreign court.

No vehicle on this site removes that risk by statute alone. The usual mitigants are contractual and operational:

• Limited-recourse clauses in contracts, confining each counterparty to the assets of the sub-fund it dealt with.
• Separate accounts at custodians, prime brokers and banks for each sub-fund.
• Clear naming of the contracting sub-fund in every agreement.
• Legal opinions on how courts in the asset and counterparty jurisdictions would treat the segregation.

The same questions apply whether the umbrella is a VCC, an SPC, an ICAV, a Luxembourg SICAV or a Hong Kong OFC. They are questions for counsel in each relevant jurisdiction, not facts this site can settle.

Umbrella or standalone funds: the trade-offs

An umbrella usually suits a sponsor planning several related strategies with the same board and service providers. Standalone funds may suit strategies with different investors, governance needs or counterparties, or where a sponsor wants full legal separation rather than statutory segregation.

Variable capital and redemptions

Variable capital lets a fund issue and cancel shares as investors subscribe and redeem, without the capital-maintenance rules that apply to trading companies. ACRA lists among a VCC's features that it "can issue and redeem shares without shareholder approval" and can pay dividends out of capital, not just profits. The Hong Kong OFC is defined by the SFC as having "variable share capital", and a SICAV is by name an investment company with variable capital.

Partnerships handle capital differently. Investors commit capital that the general partner draws down over time, and returns flow through a distribution waterfall in the partnership agreement. In Cayman, a private fund that must register with CIMA may not accept capital contributions until it is registered (Private Funds Act).

Before choosing a legal form, a sponsor should be able to answer: Will investors subscribe and redeem regularly, or commit and wait? Will there be more than one strategy? Which counterparties and asset locations will test segregation? How will investors' home tax rules classify the vehicle? The compare matrix shows these features for all eight vehicles.
