Can a US Investment Manager Manage a Cayman Fund?

Yes. A US investment manager can manage a Cayman Islands fund, and a large share of Cayman funds are managed from the United States. A manager with no Cayman establishment generally needs no Cayman licence or registration, because the Securities Investment Business Act (2020 Revision) regulates securities investment business carried on in or from within the Cayman Islands. What the offshore domicile does not change is the US analysis. Investment Advisers Act 1940 and Commodity Exchange Act obligations follow the manager's place of business, not the fund's registered office.

The Cayman answer to this question is short, and managers hear it as permission when it is only a boundary. Cayman law regulates the vehicle and the people who run it from the Islands. Every filing, every fee and every enforcement risk that attaches to a manager sitting in New York or Miami sits on the US side of the line and does not move because the fund was registered somewhere else.

Executive Summary

The Cayman fund and the US manager are separate regulatory questions with separate answers. Conflating them is the single most common structuring error, and it produces both unnecessary filings and missed ones.

• An open-ended Cayman fund is almost always registrable with CIMA under the Mutual Funds Act (2025 Revision), while a closed-ended fund registers under the Private Funds Act (2025 Revision) within twenty-one days after accepting capital commitments, and neither test refers to where the manager sits.
• A US manager operating solely from the United States is generally outside the Securities Investment Business Act altogether, because that Act regulates securities investment business carried on in or from within the Islands.
• If the manager forms a Cayman management company, that entity will usually need either a SIBA licence or registered person status, which is a registration rather than a licence, at CI$6,000 on registration and the same amount annually as at 1 January 2026.
• A US-based adviser to a Cayman private fund cannot use the foreign private adviser exemption in Advisers Act section 203(b)(3), because that definition requires no place of business in the United States.
• The realistic route below scale is the private fund adviser exemption in section 203(m) and Rule 203(m)-1, under US$150 million in private fund assets, which produces an exempt reporting adviser rather than an unregulated one.
• An offshore fund removes no US obligation, and it does not displace Advisers Act antifraud liability, Securities Act offering rules, Investment Company Act sections 3(c)(1) and 3(c)(7), CFTC jurisdiction, FATCA, or controlled foreign corporation treatment of a US-owned management company.

The Short Answer

Nothing in Cayman Islands law requires the investment manager of a Cayman fund to be Cayman-domiciled, Cayman-licensed or Cayman-resident. The Mutual Funds Act (2025 Revision) and the Private Funds Act (2025 Revision) regulate the fund. The Securities Investment Business Act (2020 Revision) regulates persons carrying on securities investment business in or from within the Cayman Islands. A Delaware LLC whose portfolio managers sit in New York, Miami or San Francisco, trading through US and offshore venues, is not carrying on business in or from within the Cayman Islands merely because its client fund is registered there.

So the Cayman answer is short. The work is on the US side, and it is not optional. A manager who reads "no Cayman licence required" as "lightly regulated" has misread the structure. The correct reading is that the Cayman regime governs the vehicle and its service provider stack, while the manager remains fully within the US regulatory perimeter it was already in.

Most published material on this question answers a different one, namely how Cayman fund managers are regulated in Cayman, and stops there. For a US manager that is the less useful half. The Cayman answer is usually "no status required", and the US answer is where the filings, the cost and the liability sit.

The Four Questions a US Manager Must Answer

Structure the analysis as four separate questions, answered in this order. They interact, but they are distinct regimes with distinct triggers. Answering them as one question is how managers end up with an exempt reporting adviser filing they did not need, or a commodity pool operator registration they did not know they needed.

Question 1 concerns the fund. Question 2 concerns any Cayman entity in the management chain. Questions 3 and 4 concern the US operating business. The management company, the general partner, the investment manager and the platform on which the fund sits are four different legal persons and should be analysed as such, a point developed in why every offshore fund launch needs a properly structured investment manager.

The Cayman Analysis: Fund Registration and Manager Status

The dividing line for the fund is redemption at the option of the investor. If investors can redeem or repurchase their equity interests at their own option, the vehicle is a mutual fund and falls under the Mutual Funds Act (2025 Revision). If they cannot, it is a private fund under the Private Funds Act (2025 Revision). A US manager running a liquid strategy will almost always be in the first category.

Open-ended: Mutual Funds Act

The commonly used route is section 4(3) registration. It requires that the minimum aggregate equity interest purchasable by a prospective investor is CI$80,000, commonly expressed as approximately US$100,000, or that the equity interests are listed on a recognised stock exchange. The alternative under section 4(4) is a limited investor fund, where 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. Both limbs are conditions rather than alternatives, and the audit requirement still applies.

The practical consequence, since the 2020 amendments removed the old exempted-fund category, is that there is effectively no unregulated open-ended Cayman fund. A US manager should not plan around one. The annual CIMA fee for a registered mutual fund is CI$4,125 under the fee schedule effective 1 January 2026, up from CI$3,675. The separate Fund Annual Return fee of CI$300 has been absorbed into that single consolidated annual fee for financial years ending after 31 December 2025. Most published cost content still lists it as a standing extra line, and it is not.

Closed-ended: Private Funds Act

Section 5(1)(a) requires application for registration within twenty-one days after acceptance of capital commitments from investors for the purposes of investments. Section 5(6) provides that the fund shall not accept capital contributions in respect of investments until it is registered. The twenty-one days runs from commitments. The prohibition bites on contributions. This distinction is routinely misdescribed, including by managers who assume they have twenty-one days from first drawdown. Private fund registration and annual fee is CI$4,125.

What none of this depends on

None of these tests refers to the manager's domicile, nationality, ownership or regulatory status. A Cayman fund managed by a US manager is registered on exactly the same basis as one managed by a Singaporean or Swiss manager. Where the manager's identity does matter is in the CIMA application pack. CIMA will want the manager's regulatory status, ownership and principals, and, where the manager is SEC-registered or an exempt reporting adviser, evidence of that. Being an exempt reporting adviser is not a deficiency. Being unable to explain why you are neither registered nor exempt is.

Does the US manager need any Cayman status?

The Securities Investment Business Act (2020 Revision) applies to a person carrying on securities investment business in or from within the Cayman Islands by way of business. Managing securities belonging to another person, where the arrangements involve the exercise of discretion, is securities investment business. The territorial limb does the work. A US management company with no Cayman office, no Cayman employees and no Cayman decision-making is generally outside SIBA entirely, and there is no Cayman filing, fee or notification for it. See SIBA explained for the underlying framework.

The position changes if a Cayman entity is inserted into the management chain, whether a Cayman investment manager, a Cayman general partner exercising discretion, or a Cayman advisory company. That entity is carrying on securities investment business in or from within the Islands and needs either a full SIBA licence or registered person status.

The Fourth Schedule limbs most relevant to a fund manager are, in substance, a company within a group of companies carrying on securities investment business exclusively for one or more companies within the same group, and a person carrying on securities investment business exclusively for sophisticated persons, high net worth persons, or a company, partnership or trust whose shareholders, unitholders or limited partners are such persons. The second limb also requires the entity to have a registered office or place of business in the Islands, serviced by a licensed provider.

Both defined terms carry monetary tests, and the Act states them in Cayman Islands dollars. A sophisticated person includes a person regulated by CIMA, a person regulated by a recognised overseas regulatory authority, a person whose securities are listed on a recognised securities exchange, and a person who by virtue of knowledge and experience in financial and business matters is reasonably regarded as capable of evaluating the merits of a proposed transaction and who participates in each single transaction with a value of at least CI$80,000. A high net worth person is an individual whose net worth is at least CI$800,000, or any person with total assets of not less than CI$4,000,000. At CIMA's published conversion basis those are approximately US$97,600, US$975,600 and US$4,878,000 respectively.

The exemption from licensing is not free-standing. It is available only where the registered person actually meets a Fourth Schedule limb on a continuing basis, registers with CIMA, pays the fees, maintains a Cayman registered office, appoints AML officers, and files an annual declaration. If the client base drifts outside the limb, the basis for registration falls away.

The Advisers Act Analysis and the Exempt Reporting Adviser Position

A person who, for compensation, engages in the business of advising others as to the value of securities or the advisability of investing in securities is an investment adviser. Managing a Cayman fund that trades securities makes the manager an investment adviser to that fund. The question is not whether the Advisers Act applies but which of registration, exemption or prohibition results.

Why the foreign private adviser exemption is not available

Section 203(b)(3) exempts a "foreign private adviser". The definition in section 202(a)(30) requires all of the following: no place of business in the United States; fewer than fifteen clients and investors in the United States in private funds advised by the adviser, in total; aggregate assets under management attributable to clients in the United States and investors in the United States in private funds of less than US$25,000,000; and that the adviser neither holds itself out generally to the public in the United States as an investment adviser nor advises a registered investment company or a business development company. A US manager fails the first condition on day one. This exemption is for non-US advisers, and it is regularly and wrongly cited by US managers who assume it is the successor to the pre-2011 exemption for advisers with fewer than fifteen clients. It is not the same exemption. Dodd-Frank repealed that one.

The private fund adviser exemption

Section 203(m) directs the Commission to exempt an adviser that acts solely as an adviser to private funds and has assets under management in the United States of less than US$150 million. Rule 203(m)-1 implements it. For an adviser whose principal office and place of business is in the United States, all of the private fund assets it manages count towards the US$150 million, wherever the funds are organised. The Cayman fund's assets count in full. There is no offshore discount.

The conditions, stated in full, are that the adviser acts solely as an investment adviser to one or more qualifying private funds, and that it manages private fund assets of less than US$150 million, calculated annually in accordance with the Form ADV instructions. A qualifying private fund is a fund not registered under section 8 of the Investment Company Act 1940 and which has not elected business development company treatment, typically a vehicle relying on section 3(c)(1) or section 3(c)(7). A single separately managed account client breaks the exemption, because the adviser is then no longer advising solely private funds. This is the most common way managers lose 203(m) without noticing, and it is worth reading alongside fund versus separately managed account before accepting an SMA mandate.

What an exempt reporting adviser actually is

An adviser relying on section 203(m) is an exempt reporting adviser. It is exempt from registration, not from the Advisers Act. It must file the required items of Form ADV Part 1A through IARD within sixty days of first relying on the exemption, and amend by annual updating amendment within ninety days after its fiscal year end. It remains subject to section 206 antifraud, Rule 206(4)-8, which reaches statements to investors and prospective investors in pooled vehicles, the pay-to-play rule 206(4)-5, and SEC examination authority. It is not subject to the custody rule, the compliance rule 206(4)-7, or Form PF.

Two further points are routinely missed. The first is state law. Exemption from SEC registration does not exempt an adviser from the law of the state in which it has a place of business, and several states impose their own private fund adviser exemption with narrower conditions, or require a notice filing and fee equivalent to exempt reporting adviser status. The second is the mid-sized adviser rule in section 203A. An adviser that is not relying on an exemption is generally prohibited from SEC registration below US$25 million of regulatory assets under management, registers with its state between US$25 million and US$100 million where the state has examination authority, and registers with the SEC at or above US$100 million.

What changes on registration

Registration brings the compliance rule, a chief compliance officer, a written code of ethics, the custody rule and the books and records rule. For a Cayman fund the custody rule is usually satisfied through the audit route: annual financial statements prepared in accordance with US GAAP, audited by an accounting firm registered with and inspected by the Public Company Accounting Oversight Board, and distributed to investors within 120 days of fiscal year end, or 180 days for a fund of funds. This creates a specific Cayman constraint that is easy to miss at the point of appointing an auditor. A Cayman registered fund's auditor must be approved by CIMA and must sign off locally. If the manager expects to register with the SEC within a year or two, the auditor needs to be both CIMA-approved and PCAOB-registered from the outset. Changing auditor after year one is possible but wasteful. See Cayman hedge fund audit and first-year filings.

Commodity Pool Status and the CFTC Analysis

If the Cayman fund holds any commodity interest, meaning a futures contract, an option on a futures contract, a swap, or a retail forex transaction, it is a commodity pool. The person operating it is a commodity pool operator required to register under section 4m(1) of the Commodity Exchange Act unless an exemption applies. This catches more funds than managers expect. A long/short equity fund using index futures for hedging is a commodity pool. A digital asset fund trading bitcoin or ether futures on a US-regulated futures exchange, or offshore perpetual instruments properly characterised as swaps or futures, is a commodity pool. Spot-only trading is generally not a commodity interest, though the CFTC retains antifraud and anti-manipulation authority over spot commodity markets.

Regulation 3.10(c)(5): the one that does not help a US manager

The registration relief for foreign operators of offshore pools sits at 17 CFR 3.10(c)(5). Older memoranda and a good deal of secondary commentary still cite Regulation 3.10(c)(3), which is the correct citation only for the pre-2020 text. The Commission restructured paragraph (c) with effect from 7 December 2020, and paragraph (c)(3) now deals with exempt introducing brokers.

Under Regulation 3.10(c)(5)(i), a foreign located person, defined as a person located outside the United States, its territories or possessions, engaged in the activity of a commodity pool operator is not required to register in that capacity where the covered transactions are executed on behalf of a commodity pool whose participants are all foreign located persons or international financial institutions. Regulation 3.10(c)(5)(iii) sets out when a pool is treated as operated in accordance with that paragraph, and each of the following must hold:

• The pool is organised and operated outside the United States, its territories or possessions.
• The pool's offering materials and any underwriting or distribution agreements include clear written prohibitions on offering to participants located in the United States and on US ownership of participation units.
• The pool's constitutional documents and offering materials are reasonably designed to preclude persons located in the United States from participating, and include mechanisms reasonably designed to enable the operator to exclude any such persons who attempt to participate notwithstanding those prohibitions.
• The operator exclusively uses non-US intermediaries for the distribution of participations.
• The operator uses reasonable investor due diligence methods at the time of sale to preclude persons located in the United States from participating.
• Participation units are directed and distributed to participants outside the United States, including on secondary markets organised and operated outside the United States where the operator has reasonably determined US participation is unlikely.

Two features of the current text are worth stating precisely. Regulation 3.10(c)(5)(iv) confirms that using the relief for a qualifying pool does not affect the operator's ability to register, or to claim other relief, in respect of pools that are not eligible, so the relief operates pool by pool rather than firm-wide. Regulation 3.10(c)(5)(v) preserves section 4o of the Act, so the antifraud provision continues to apply. Neither point rescues a manager located in the United States. The relief is available only to a foreign located person, whatever the fund's domicile, and it is closed where the pool admits US participants. It is the exemption most often cited in support of the belief that an offshore fund removes CFTC obligations, and it is the exemption least likely to be available to the person citing it.

Regulation 4.13(a)(3): the de minimis exemption, stated in full

Regulation 4.13(a)(3) exempts a person from CPO registration in respect of a pool where all of the following are satisfied on a continuing basis:

1. Interests in the pool are exempt from registration under the Securities Act 1933 and are offered and sold without marketing to the public in the United States;
2. The pool meets one of two trading tests at all times. Either aggregate initial margin, premiums and required minimum security deposit for retail forex do not exceed 5% of the liquidation value of the pool's portfolio, after taking into account unrealised profits and unrealised losses, or the aggregate net notional value of the pool's commodity interest positions does not exceed 100% of the liquidation value of the pool's portfolio;
3. Interests are offered and sold only to accredited investors, trusts formed by accredited investors, knowledgeable employees, or qualified eligible persons within the meaning of the relevant limb of Regulation 4.7;
4. The operator reasonably believes, at the time of the investment, that each participant meets one of those categories; and
5. Participation units are not marketed as or in a vehicle for trading in the commodity futures, commodity options or swap markets.

The exemption is claimed by electronic notice filed with the National Futures Association, and, as an operational matter, it must be reaffirmed annually within sixty days of the calendar year end. A lapsed reaffirmation is a common and entirely avoidable finding. Note also that Regulation 4.13(a)(4), which many older memoranda still cite, was rescinded in 2012 and does not exist.

Regulation 4.7 is relief from disclosure, not from registration

Regulation 4.7 is different in kind. It gives a registered commodity pool operator relief from certain disclosure, periodic reporting and recordkeeping requirements for pools offered solely to qualified eligible persons. It does not exempt the operator from registration. Its current text reflects amendments published on 26 September 2024, which added a condition that any offering memorandum distributed in connection with soliciting prospective participants must contain all disclosures necessary to make the information in it not misleading, and must carry a prescribed CFTC legend on its cover page or immediately above the subscription signature line.

The qualified eligible person Portfolio Requirement was not increased by those amendments. As the regulation currently stands, a person satisfies it by owning securities and other investments of unaffiliated issuers with an aggregate market value of at least US$4,000,000, or by having had at least US$400,000 in exchange-specified initial margin, option premiums and required minimum security deposits on deposit with a futures commission merchant at any time in the preceding six months, or by holding a combination of the two that totals one hundred per cent of the respective minimums. Separately, a manager advising the pool may be a commodity trading advisor requiring registration under section 4m(1), with relief available under Regulation 4.14 on its own conditions.

For managers in digital assets specifically, the interaction between CFTC registration and offshore structures is developed further in CLARITY Act, CFTC registration and offshore fund managers.

What an Offshore Fund Does Not Do for You

The question "can a US manager manage a Cayman fund" is often not a question about permission. It is a hope that the answer is "yes, and it makes the US problem go away". It does not.

What the offshore fund does do is real and worth stating precisely, because the legitimate reasons are strong enough not to need embellishment. A Cayman vehicle is the market-standard access point for non-US investors and US tax-exempt investors, who would otherwise face US withholding and, in the case of tax-exempt investors, unrelated business taxable income on leveraged returns. It is a blocker, not a shield. The general framework relied on to prevent the offshore fund itself being treated as engaged in a US trade or business, notwithstanding that its manager sits in the United States, is the trading safe harbour in section 864(b)(2) of the Internal Revenue Code, which covers trading in securities and commodities for the fund's own account. Its boundaries, particularly around lending, origination and dealer activity, are precisely where funds get into difficulty. That analysis belongs with US tax counsel before the strategy is fixed, not after.

Where the Management Company Should Sit

Three patterns cover the overwhelming majority of US manager launches. The choice is usually driven by ownership and investor base, not by tax, for the reasons set out above.

The honest summary is that for a US-owned, US-operated manager the US-only management company is right in most cases, and the offshore management company is a solution looking for a problem unless there is a specific non-tax reason for it. Where an offshore management company genuinely is warranted, the design questions are set out in setting up an offshore management company alongside a fund launch and offshore fund management companies for emerging managers.

Practical structures in use

Four configurations account for most US manager launches into Cayman.

Standalone Cayman fund with a US investment manager. A Cayman exempted company registered under section 4(3) of the Mutual Funds Act, a Delaware LLC as investment manager, and, where there is a US onshore feeder or a Delaware limited partnership, a separate Delaware general partner. The manager files as an exempt reporting adviser if it is within Rule 203(m)-1, or registers if it is not. This is the cleanest structure and the one allocators find easiest to diligence.

Master-feeder. A Cayman master fund with a Cayman offshore feeder and a Delaware onshore feeder, for a manager with both US taxable and non-US or US tax-exempt investors. The master registers with CIMA where the registration conditions are met, at CI$3,075 annually under the 1 January 2026 fee schedule. Master-feeder is correct at scale and premature below it. The case against reaching for it too early is made in emerging managers do not need a master-feeder, and the mechanics are set out in Cayman master-feeder structures.

Segregated portfolio on a platform. The manager takes a segregated portfolio within an established, already-registered Cayman segregated portfolio company, and its US entity is appointed as investment manager or trading adviser to that portfolio. The regulatory analysis on the US side is identical. What changes is the Cayman-side execution. A standalone launch requires the manager to separately source, negotiate, contract with, pay and coordinate registered office and corporate services, independent directors, AML officers (an AMLCO, an MLRO and a deputy MLRO who must be a different person), a fund administrator, a CIMA-approved auditor, formation counsel and offering document counsel, banking, custody, counterparty onboarding, regulatory filing agents and directors and officers cover. Each is a separate engagement, a separate fee, a separate onboarding cycle and a separate point of failure, and the coordination falls on the manager at exactly the point they should be raising capital. A platform consolidates that into a single engagement against infrastructure that already exists. The aggregate fee is generally lower at the margin, but the more material point is that the fragmentation cost is largely invisible in a standalone budget and is borne in elapsed time as much as in fees.

Standalone is the better answer for managers running an existing multi-fund programme, managers whose allocators mandate a dedicated vehicle, managers needing a bespoke structure an umbrella cannot accommodate, and managers at sufficient scale that the fixed cost is immaterial. The comparison is set out at length in platform versus standalone: a full cost, timeline and risk comparison.

Cayman IM with US sub-adviser. Used where genuine decision-making or ownership sits outside the United States. The Cayman IM needs SIBA registered person status or a licence and real substance, and the US sub-adviser remains within the Advisers Act. This structure is over-used relative to the number of cases where it is justified.

The Decision Sequence

Work through these in order. Each step has a determinate answer given the facts, and none of them can be skipped on the basis of the fund's domicile.

What this article does not cover, and what varies

Deliberately excluded: US tax structuring beyond the framing above, ERISA plan asset analysis where benefit plan investors approach 25% of a class, state-by-state adviser registration, bank and broker-dealer status questions, marketing rule application to fund materials, and non-US distribution regimes such as UK and EU private placement. Genuinely uncertain or fact-dependent: whether particular offshore digital asset instruments are commodity interests; whether a given advisory arrangement breaks the condition that the adviser acts solely for qualifying private funds; whether a Cayman entity's activities amount to securities investment business carried on in or from within the Islands where decision-making is split across jurisdictions; and how the core income generating activities of fund management business are assessed where portfolio management is delegated away from the Cayman entity. On each of these, reasonable practitioners differ, and a manager should get a written position rather than an oral comfort.

Key Takeaways

• Answer the four questions in sequence, fund registration first, Cayman manager status second, Advisers Act third and commodity pool status fourth, and get each in writing from the counsel who owns it.
• Do not insert a Cayman management company unless a genuine non-US function or ownership group requires it, because it adds SIBA registration, corporate services and economic substance obligations without changing the US analysis.
• Test Rule 203(m)-1 before accepting any separately managed account mandate, because a single non-fund client ends the exemption and forces registration or a restructuring.
• Diary the exempt reporting adviser deadlines on day one: the initial Form ADV Part 1A filing within sixty days of first reliance, and the annual updating amendment within ninety days after fiscal year end.
• Re-test commodity pool status every time the instrument set changes, and where Regulation 4.13(a)(3) is claimed, calendar the annual reaffirmation within sixty days of the calendar year end.
• Appoint an auditor that is both CIMA-approved and PCAOB-registered from the outset if SEC registration is plausible within two years, because changing after year one wastes time and cost.

Frequently Asked Questions

Can a US investment manager manage a Cayman fund?

Yes. Cayman Islands law imposes no requirement that a fund's investment manager be Cayman-domiciled or Cayman-licensed. The Securities Investment Business Act (2020 Revision) applies only to securities investment business carried on in or from within the Cayman Islands, so a US manager with no Cayman establishment is generally outside it. The manager's US obligations under the Investment Advisers Act 1940 and the Commodity Exchange Act are unaffected by the fund's domicile.

Do I need to register with the SEC to manage an offshore fund?

Not necessarily, but you must have a stated basis. A US-based manager acting solely as adviser to qualifying private funds with less than US$150 million in private fund assets under management can rely on Advisers Act section 203(m) and Rule 203(m)-1, becoming an exempt reporting adviser. That requires filing the prescribed items of Form ADV Part 1A within 60 days of first reliance and an annual updating amendment within 90 days after fiscal year end. Offshore domicile does not reduce the asset count.

Does a US manager need a Cayman licence to manage a Cayman fund?

No, provided no part of the management chain sits in or operates from the Cayman Islands. If a Cayman management company is used, it needs a full licence under the Securities Investment Business Act (2020 Revision) or registered person status under section 5(4) and the Fourth Schedule. Registered person status is a registration, not a licence, and costs CI$6,000 on registration and annually as at 1 January 2026.

Does an offshore fund avoid US regulation?

No. The Advisers Act follows the adviser's place of business, not the fund's registered office. Section 206 antifraud applies whether or not the adviser is registered. A Cayman fund with US investors must still fit section 3(c)(1), generally not more than 100 beneficial owners, or section 3(c)(7), sell interests under a valid private placement exemption such as Rule 506, and report under FATCA through the Cayman DITC regime.

Should a US manager set up a Cayman management company?

Usually not, if the reason is tax. A Cayman management company owned by US persons is generally a controlled foreign corporation whose fee income is taxed currently under Subpart F and GILTI, and section 457A has largely eliminated offshore deferral since 2008. It also triggers SIBA status at CI$6,000 annually plus corporate services, and brings the entity within the economic substance definition of fund management business. It is justified where a genuine non-US business function or ownership group requires it.

Does a Cayman fund need to register with the CFTC?

The fund does not register, but its operator may have to. If the fund holds any futures, option on futures, swap or retail forex position, it is a commodity pool and its operator must register as a commodity pool operator under section 4m(1) of the Commodity Exchange Act unless an exemption applies. The usual route is CFTC Regulation 4.13(a)(3), which requires all five of its conditions, a notice filing with the National Futures Association, and annual reaffirmation within 60 days of calendar year end. Regulation 3.10(c)(5) relief is available only to an operator located outside the United States.
