Delaware and Cayman Parallel Fund Formation: When to Use a Cayman Exempted Limited Partnership

• A parallel fund structure lets a Delaware fund and a Cayman fund invest directly alongside each other. In a master-feeder structure, investors enter through feeder funds that invest in a shared master fund.
• A Delaware-only fund may suit your investor base if its tax and regulatory needs permit direct investment. A Cayman-only fund may suit a different investor mix, while parallel funds add flexibility and separate operating costs.
• Investor location alone does not decide the structure. Review each investor's tax status, investment restrictions, and potential exposure to U.S. taxable income.
• A Cayman vehicle adds formation and ongoing compliance work, including an assessment of registration under the Private Funds Act.
• Zecca Ross Law Firm P.C. provides U.S. fund counsel with a scoped, flat-fee approach and coordinates with separately engaged Cayman counsel. The firm does not provide Cayman legal advice.

What a parallel fund structure is and how it differs from a master-feeder

A parallel fund structure uses two or more funds to invest side by side in the same portfolio companies. For example, a Delaware limited partnership and a Cayman exempted limited partnership may each admit their own investors and acquire their own stake in a startup. The manager coordinates deal terms and allocates each investment between the funds under a documented policy.

A master-feeder can serve different investor groups, but its feeders generally hold interests in the master rather than direct portfolio investments. An emerging manager may prefer parallel funds when separate Delaware and Cayman vehicles help address investor-specific tax or regulatory requirements while preserving separate ownership of portfolio assets. Investor location alone does not establish that need. Zecca Ross Law Firm P.C. can coordinate the U.S. fund documents and structure with separately engaged Cayman counsel, who advises on the Cayman vehicle.

Why investor location alone doesn't decide the entity choice

A non-U.S. investor can often invest directly in a Delaware limited partnership. The first question is whether the investor's tax position and the fund's expected investments make that workable. For example, a foreign investor may accept the U.S. tax filings and potential withholding associated with its Delaware LP interest. Another may need a different structure because the fund expects investments that produce income effectively connected with a U.S. trade or business, often called ECI.

Tax-exempt investors may focus on unrelated business taxable income, or UBTI. A Cayman exempted limited partnership does not, by itself, eliminate UBTI or ECI exposure. Qualified tax counsel must examine the investments and each vehicle's tax treatment before deciding whether a corporate blocker or another arrangement is appropriate.

Investor requirements can also affect the choice. An ERISA plan may need a plan-asset analysis, while a sovereign wealth fund or fund of funds may have policies governing where it can invest. You should ask prospective limited partners about those requirements before forming an offshore vehicle. A Cayman fund that falls within the Private Funds Act may also face CIMA registration and ongoing obligations, adding counsel, administration, and compliance costs.

The decision table that follows weighs those investor requirements and costs against Delaware-only, Cayman-only, and parallel structures. For a U.S.-based manager, Zecca Ross Law Firm P.C. can coordinate the U.S. fund analysis with separately engaged Cayman counsel, who handles Cayman-law advice.

Delaware-only, Cayman-only, or parallel: decision table

Before choosing a parallel structure, test the expected investor commitments against the added work of operating two funds. A manager might begin with a Delaware LP and discover that a prospective tax-exempt investor needs further tax analysis, while another investor's policy calls for an offshore vehicle. The worked example that follows traces how those requirements affect the decision before either fund is formed.

Worked hypothetical: an emerging manager raising from U.S. and non-U.S. LPs

Hypothetical for illustration, not legal or tax advice. Mesa Grove Ventures plans to raise an $18 million first fund. U.S. taxable investors expect to commit $12 million, a U.S. university endowment expects to commit $3 million, and a non-U.S. institution expects to commit $3 million. The manager expects both funds to invest directly in the same startups, rather than send capital through feeders into a master fund.

Mesa Grove first asks tax counsel what each investor needs. The non-U.S. institution may be able to invest in a Delaware limited partnership, so its address alone does not justify a Cayman vehicle. Tax counsel instead examines the fund's expected investments and each investor's potential exposure to U.S. taxable income. If the endowment or institution requires a different structure, the manager can compare the cost of a Cayman exempted limited partnership with the risk of losing those commitments.

For the Delaware fund, Mesa Grove forms a general partner entity and a separate investment manager. U.S. counsel drafts the Delaware limited partnership agreement and evaluates the offering and adviser rules that apply to the U.S.-based manager. If Mesa Grove chooses a parallel Cayman fund, separately engaged Cayman counsel advises on its general partner, forms the Cayman ELP, and assesses registration under the Private Funds Act. U.S. counsel coordinates the documents but does not give Cayman legal advice or make Cayman filings.

The two partnership agreements need compatible fees, carried interest, investment limits, and key-person terms. Mesa Grove also needs a written policy for allocating each investment and any co-investment opportunity between the funds. If the endowment negotiates a side letter granting reporting rights, counsel checks whether either fund's most-favored-nation terms require an offer of comparable rights to other eligible investors. Mesa Grove should authorize the added Cayman work only after tax counsel and prospective investors establish a concrete need for it, with the scope and cost of both counsel's work agreed before formation.

GP, manager, and LPA coordination across parallel vehicles

Each parallel fund typically has its own general partner, while a common investment manager directs investments through separate management agreements. The Delaware LP and Cayman exempted limited partnership therefore remain separate funds, even when they buy the same securities. Zecca Ross Law Firm P.C. can draft and coordinate the U.S. documents, while separately engaged Cayman counsel advises on the Cayman entities and documents.

The two limited partnership agreements should use compatible terms wherever investors share a portfolio. Counsel should compare management fees, carried interest, key-person provisions, investment-period suspensions, and voting rights so a decision affecting one fund does not produce an unintended result in the other. Terms can differ where investor needs or applicable law require it, including tax reporting and eligibility provisions. The agreements should state how the manager resolves any difference that affects a shared investment.

A written allocation policy should govern deals before the manager faces a contested opportunity. It can set a starting allocation based on available commitments, then specify adjustments for investment limits, remaining capacity, follow-on reserves, and investor exclusions. The policy should also address who pays broken-deal expenses and when the manager may offer co-investment outside the funds. For example, if one fund cannot participate in a portfolio company's follow-on round, the manager should document why the other fund receives a larger allocation rather than treating the change as automatic.

Side letters need a cross-fund check because an investor's negotiated right may affect allocations or economics elsewhere. Most-favored-nation provisions should identify which investors may elect a term and whether rights granted by the other fund count. Zecca Ross can coordinate those U.S. drafting decisions as part of its fund formation work, with Cayman counsel reviewing the Cayman documents and Cayman-law effects.

U.S. securities law, Investment Adviser Act, and state adviser analysis

A Delaware/Cayman parallel fund needs a separate U.S. securities analysis for each vehicle that offers interests to investors. A manager commonly considers Regulation D for private offerings. Rule 506(b) generally prohibits public solicitation, while Rule 506(c) permits it if every purchaser is accredited and the issuer takes reasonable steps to verify that status. The offering documents and sales process must follow the exemption each vehicle relies on. Forming a Cayman vehicle does not exempt an offer to U.S. investors from U.S. securities rules.

The U.S.-based manager must also assess its own status under the Investment Advisers Act. An adviser that solely advises qualifying private funds may be able to rely on the federal private fund adviser exemption if its U.S. private fund assets under management remain below $150 million. Exemption from SEC registration does not necessarily eliminate reporting duties or state requirements. Counsel should assess the manager's activities and assets across both vehicles rather than treating the Cayman fund as outside the analysis.

A California-based manager needs a separate state adviser review. The California Department of Financial Protection and Innovation's adviser guidance describes the state application process. Counsel must determine whether California registration or an applicable exemption governs the manager's particular activities. For example, adding a Cayman parallel fund for non-U.S. limited partners does not, by itself, resolve the California adviser question for a manager operating there.

Zecca Ross Law Firm P.C. can coordinate the U.S. offering and adviser analysis with separately engaged Cayman counsel. Cayman formation and regulatory determinations require Cayman counsel and are addressed separately.

Tax coordination between Delaware and Cayman vehicles

Tax counsel should review the proposed Delaware and Cayman vehicles before you settle their ownership and investment terms. A common reason to consider a Cayman parallel vehicle is to address potential unrelated business taxable income, or UBTI, for U.S. tax-exempt investors and effectively connected income, or ECI, for non-U.S. investors. A Cayman exempted limited partnership does not itself block either type of income. Depending on the investments and investors, tax counsel may recommend a corporate blocker or a different arrangement.

The review should follow the income each vehicle may receive and identify who bears the tax cost of any blocker. For example, if both funds invest in a U.S. operating partnership, counsel should assess the consequences separately for a U.S. university endowment and a non-U.S. limited partner before assigning them to a vehicle. U.S. tax counsel should assess federal, state, and investor-specific consequences, while separately engaged Cayman counsel should advise on Cayman-law aspects. Zecca Ross Law Firm P.C. can coordinate the U.S. fund documents with those advisers, but it does not provide Cayman legal advice. Qualified tax counsel must determine the treatment of each proposed entity and investor.

Cayman ELP formation and CIMA registration basics

A Cayman exempted limited partnership (ELP) requires separate Cayman formation work even when it will invest alongside an existing Delaware fund. You should agree on the proposed general partner, partnership terms, and investor documents before Cayman counsel handles the entity's formation and confirms the applicable Cayman requirements. Zecca Ross Law Firm P.C. can coordinate the U.S. fund documents and legal analysis, but it does not act as Cayman legal counsel.

A Cayman ELP does not require CIMA registration merely because it exists. The Private Funds Act sets out which investment vehicles qualify as private funds, including requirements concerning pooled investor funds, investor control, and management of the investments as a whole. A Cayman ELP raising commitments to invest alongside a Delaware LP may fall within that definition, but separately engaged Cayman counsel must assess the actual terms and any applicable exclusions.

If the ELP qualifies as a private fund, the Act requires an application for CIMA registration within 21 days after it accepts capital commitments for investments. The fund cannot accept capital contributions for investments before CIMA registers it. You should build that sequence into the closing timetable rather than assume that signing subscription documents permits an immediate capital call.

This section provides general orientation, not Cayman legal advice. Cayman counsel must make the Cayman-law determinations and handle any CIMA filings. Before publication, Cayman counsel should also check whether any 2026 amendments affect the Act's definition, registration deadline, or continuing obligations. No 2026 amendments have been verified for this draft.

Step-by-step: building a Delaware/Cayman parallel fund structure

1. Test whether you need two funds. Identify each prospective investor's tax status, investment requirements, and expected commitment. Ask qualified tax counsel whether a Delaware LP can admit the investors directly or whether a Cayman vehicle would address a specific concern. Investor location alone does not settle the choice.
2. Set up the U.S. GP and manager. Decide which entity will act as general partner and which will provide investment management services. Document authority, compensation, and ownership before drafting the fund terms. Separately engaged Cayman counsel should advise on any Cayman entity or GP requirements.
3. Draft coordinated fund agreements. Prepare a Delaware limited partnership agreement and work with Cayman counsel on the Cayman agreement. Match the intended economics, key-person terms, and investment strategy. Write an allocation policy that explains how each fund receives its share of investments, expenses, and co-investment opportunities. Review side letters across both vehicles for conflicting promises.
4. Complete the U.S. securities and adviser analysis. U.S. counsel should assess the offering exemption, investor eligibility, and federal and state adviser obligations before subscriptions begin. A Cayman parallel fund does not remove U.S. adviser questions for a U.S.-based manager. For a California-based manager, California DFPI adviser guidance belongs in that review.
5. Engage Cayman counsel for formation and registration. Cayman counsel should form the exempted limited partnership and determine whether the fund must register with CIMA under the Private Funds Act. Have Cayman counsel confirm the law's current text, including any 2026 amendments, before relying on a registration plan or launching the offering.
6. Recheck tax treatment before closing. Qualified tax advisers should review the proposed investor placement, investment types, and treatment of income and expenses in both vehicles. Revise the documents if that review changes how the funds should invest or allocate costs.
7. Close each vehicle under its own documents. Collect subscriptions, complete investor checks, accept commitments, and establish procedures for capital calls and shared investments. Zecca Ross Law Firm P.C. can serve as U.S. fund counsel and coordinate the two workstreams. Separately engaged Cayman counsel remains responsible for Cayman-law advice, formation, and CIMA matters.

Frequently asked questions

• How does a Delaware/Cayman parallel fund differ from a master-feeder fund? Parallel funds invest directly in portfolio companies alongside each other. In a master-feeder structure, investors enter through separate feeders that invest in a common master fund. Zecca Ross can draft and coordinate the U.S. fund documents, while separately engaged Cayman counsel handles Cayman documents. For example, two parallel funds might each purchase shares in the same startup, with each fund's investment amount determined under a documented allocation policy.
• Does a non-U.S. investor need to invest through a Cayman fund? No. A Delaware limited partnership may admit a non-U.S. investor, but the investor's tax position, internal policies, and exposure to U.S. income can affect the choice. U.S. counsel and tax advisers should assess those concerns before the manager pays to form a second vehicle, while Cayman counsel evaluates any proposed Cayman structure. For example, a non-U.S. family office may accept a Delaware fund after its tax adviser reviews the proposed investments.
• When should an emerging manager add a Cayman exempted limited partnership? Add one when identified investor needs or the investment strategy justify the extra formation and operating work. Do not use investor location alone as the test. Zecca Ross can compare the U.S. fund terms and investor requirements with tax advisers, and separately engaged Cayman counsel can advise on ELP formation and Cayman obligations. For example, a prospective tax-exempt investor's concerns about taxable income may warrant a Cayman option, subject to investor-specific tax advice.
• Can the same general partner and manager oversee both parallel funds? A manager can plan common control and coordinated investment decisions, but counsel must review the entities and each fund's governing documents. The two LPAs should address economics, key-person terms, and investment allocations consistently where the funds share a strategy. Zecca Ross can prepare the U.S. entity and LPA work, while Cayman counsel advises on the Cayman vehicle and its governing arrangements. For example, both funds might participate in one financing under an allocation policy that accounts for available capital and investor restrictions.
• How should side letters work across two parallel funds? Each fund should track its investor promises against its own LPA and the manager's allocation policy. A most-favored-nation right may require careful review when one investor asks for terms unavailable or unsuitable in the other vehicle. Zecca Ross can coordinate U.S. side-letter terms with the manager, while Cayman counsel reviews terms affecting the Cayman fund. For example, an investor's restriction on a particular industry could change that fund's share of a deal without changing the other fund's commitments.
• Does a Cayman parallel fund remove U.S. securities or adviser requirements? No. A U.S.-based manager still needs a U.S. securities-offering and investment-adviser analysis for its activities, including applicable federal and state requirements. California-based managers should review California DFPI's adviser guidance with U.S. counsel, while Cayman counsel addresses separate Cayman requirements. For example, a manager working from California cannot assume that placing some investors in an ELP resolves its California adviser question.
• Will a Cayman ELP need to register with CIMA? Registration depends on whether the vehicle falls within the Private Funds Act and how it operates. A manager should obtain a Cayman-law assessment before relying on an assumed exemption or setting a closing date. Zecca Ross can coordinate the U.S. closing schedule, but separately engaged Cayman counsel must determine the Cayman filing requirements and handle Cayman practice. For example, a manager planning a first closing should ask Cayman counsel to assess registration before accepting commitments through the ELP.

Choosing counsel for a Delaware/Cayman parallel fund

Choose U.S. fund counsel before you commit to a Delaware-only fund or a Delaware/Cayman parallel structure. Counsel needs to review the expected investors, proposed allocations, U.S. securities and adviser obligations, and tax questions with qualified tax advisers. Separately engaged Cayman counsel should assess Cayman formation and regulatory requirements. Filing two entities before resolving those questions can leave you with fund documents that do not fit the investor mix.

Zecca Ross Law Firm P.C. advises emerging managers on fund formation and can coordinate the U.S. work with separately retained Cayman counsel. The firm does not provide Cayman legal advice or replace Cayman counsel. If you want a boutique alternative to BigLaw, ask Zecca Ross about direct attorney involvement and a defined flat-fee scope. Confirm which U.S. deliverables the fee covers and budget separately for Cayman counsel and tax advice.
