Hedge fund structures and operations

What distinguishes a hedge fund operationally

“Hedge fund” is not one legal form or one strategy. It commonly describes a privately offered pooled vehicle using a flexible investment mandate that may include public securities, derivatives, short positions, commodities, digital assets, credit, or relative-value strategies. The structure may be open-ended, allowing periodic subscriptions and redemptions, or closed-ended where the assets and liquidity require committed capital.

The operating design follows the strategy. A liquid long-short equity fund needs brokerage, custody, daily position data, valuation sources, and redemption liquidity. A digital-asset fund needs wallet and exchange controls. A concentrated activist or private-credit vehicle may need gates, longer lockups, and asset-specific valuation. The label does not answer any of those questions.

Before choosing a domicile, document the instruments, markets, liquidity, expected investors, dealing frequency, use of borrowing and derivatives, custody model, valuation sources, and manager location. Then map the securities, investment-adviser, commodity, AML, tax, and marketing consequences.

Open-ended and closed-ended structures

An open-ended fund issues and redeems interests around periodic dealing dates at a price based on net asset value. Investors may face notice periods, lockups, gates, side pockets, suspension provisions, and other liquidity controls. The manager must align promised liquidity with the time required to sell assets and settle obligations.

A closed-ended fund generally accepts commitments during fundraising, calls capital over an investment period, realizes assets over a fixed or extendable term, and distributes proceeds. Private equity and venture funds commonly use this model because their assets cannot be reliably sold to meet periodic redemption requests.

Choose based on asset liquidity and portfolio construction, not investor preference alone. Offering quarterly redemption against hard-to-value, thinly traded assets creates a mismatch. The documents should explain the dealing calendar, notice, valuation point, settlement, reserves, gates, suspension, side pockets, in-kind distributions, and manager discretion.

Offshore versus onshore

An offshore vehicle may be considered because of investor tax profiles, cross-border distribution, service-provider ecosystems, legal familiarity, or operational requirements. It is not automatically tax free, lightly regulated, or suitable for every investor. The manager and marketing activity can create obligations in other countries regardless of domicile.

Compare candidate structures across the fund, manager, and investor layers. Consider authorization or registration, eligible investors, offering routes, tax classification, withholding, reporting, audit, beneficial ownership, AML, substance, directors, administration, custody, banking, enforcement, and liquidation.

US taxable, tax-exempt, and non-US investors may prefer different feeders into a common master portfolio. A parallel or master-feeder structure can reduce some conflicts but adds entities, allocations, tax work, cash movement, and reconciliations. Complexity should be supported by committed investor demand, not copied from a larger fund.

Core documents

The package often includes formation records, articles or partnership agreement, offering memorandum, subscription agreement, management or advisory agreement, administration agreement, prime brokerage and custody agreements, valuation policy, AML documents, side letters, and trading counterparty agreements.

The offering and governing documents should define the strategy, instruments, borrowed exposure, investment restrictions, dealing terms, valuation, fees, expenses, side pockets, gates, suspensions, transfers, conflicts, allocations, service providers, reporting, manager authority, indemnity, and termination.

The strategy description must be specific enough to disclose risk without freezing legitimate trading judgment. “Any asset anywhere” does not help an investor understand exposures or help an administrator price the portfolio. Identify expected instruments, geographic scope, liquidity, concentration, derivatives, shorting, financing, and material operational dependencies.

Initial offering and subscriptions

The initial offering period is the window used to accept the first subscriptions before the fund begins regular dealing. The documents should identify the closing or launch date, minimum fund size if any, subscription deadline, initial price, payment deadline, conditions to launch, and treatment if the threshold is not met.

After launch, a subscription should move through investor approval, signed documents, cleared cash, dealing-date eligibility, unit or share calculation, register update, and confirmation. Apply cutoffs consistently. Late money should not receive an earlier valuation date unless the documents and approved exception process permit it.

Different share classes may reflect currency, fee terms, liquidity, investor category, hedging, or minimum size. Maintain class-level terms and NAV accurately. A side letter that changes economics or liquidity must reach the administrator and conflict process.

NAV, expenses, and equalization

NAV is assets minus liabilities, calculated under the fund's documents and accounting policy. For an open-ended fund, NAV supports subscriptions, redemptions, performance fees, and reporting. The process needs positions, cash, receivables, payables, accrued fees, expenses, FX rates, price sources, and treatment of hard-to-value assets.

Expenses reduce NAV. Establish which costs belong to the manager and which may be charged to the fund. Accrue audit, administration, directors, legal, regulatory, data, financing, and other fund expenses in the periods they relate to rather than recognizing them only when paid.

Equalization, series accounting, or another method may be used so investors entering at different times bear performance fees fairly. The method must match the documents and administrator's capabilities. A simple “20 percent incentive fee” description is incomplete without the crystallization period, high-water mark, hurdle if any, loss carryforward, allocation method, and treatment of subscriptions and redemptions.

The fund economics guide explains the broader fee and waterfall questions, while fund administration covers NAV controls.

Custody, prime brokerage, and banking

A bank account handles cash. A custodian holds or verifies ownership of assets. A prime broker may provide execution, financing, securities lending, custody, and reporting. An exchange provides a market and may hold assets or collateral. These roles can overlap, but they should not be treated as interchangeable.

Map assets by location and legal relationship. Record which entity is the client, whose name appears on an account or wallet, how assets are segregated, what may be rehypothecated, how collateral moves, which subcustodians are used, and what happens on provider insolvency.

Reconcile positions and cash independently of the portfolio manager. Obtain external statements and investigate differences. Diversify material counterparty exposure where proportionate, monitor credit and operational risk, and preserve the ability to transfer assets if a provider fails.

Commodity and derivatives considerations

A US manager operating a pool that trades commodity interests may be a commodity pool operator, and advisers may have commodity trading adviser implications. Registration, exemption, disclosure, reporting, and recordkeeping depend on the activity and participants. The CFTC directs market participants to its framework and NFA registration resources.

Analyze this before trading futures, commodity options, retail foreign exchange, swaps, or digital-asset derivatives. Do not assume an investment-adviser exemption also resolves commodity regulation. Preserve any exemption filing, annual affirmation, trading limits, and calculation evidence.

Derivatives also affect collateral, liquidity, counterparty exposure, valuation, legal agreements, and investor disclosure. Stress tests should include margin increases, market closures, basis moves, and counterparty failure.

Crypto funds

Digital assets add wallet, key-management, blockchain, exchange, pricing, sanctions, market-integrity, and fork or airdrop questions. “Supported exchange” is the wrong first question. Start with which legal entity owns the account, whether the venue may serve it, custody and segregation, withdrawal controls, counterparty exposure, permitted tokens and jurisdictions, pricing, and recovery.

Separate trading venues from qualified or regulated custody analysis under the applicable framework. Use allowlisted addresses, multi-person approval, hardware or institutional key controls, transaction simulation where appropriate, and independent reconciliation between blockchain, custodian, exchange, and accounting records.

Crypto subscriptions and redemptions require explicit rules for accepted assets, wallet screening, valuation timestamp, network fees, settlement finality, failed or wrong-token transfers, taxes, and whether in-kind dealing is permitted. Fiat banking remains necessary for many expenses and obligations even when portfolio assets are digital.

Segregated portfolio companies

A segregated portfolio company, or SPC, is a corporate form available in certain jurisdictions that can create legally segregated portfolios under one company. Each portfolio may have separate assets and liabilities while sharing the corporate shell and some providers. Names usually identify both the company and portfolio.

An SPC is not the same as a standalone SPV. It can improve operational efficiency for multiple strategies or investor groups, but it introduces umbrella governance, allocation, cross-portfolio service arrangements, and jurisdiction-specific insolvency questions. Confirm whether counterparties recognize the segregation and execute documents with the correct portfolio designation.

Maintain separate books, accounts, contracts, and attribution for each portfolio. Shared expenses need a documented allocation policy. A new portfolio should pass the same strategy, offering, manager, AML, banking, custody, and tax analysis as a standalone vehicle.

Operating checklist

• Match fund liquidity to the assets, financing, and settlement cycle.
• Choose domicile only after mapping investors, manager, markets, tax, and providers.
• Make strategy, dealing, valuation, fee, expense, and liquidity terms operationally testable.
• Reconcile portfolio records to independent bank, broker, custodian, and exchange evidence.
• Model subscriptions, redemptions, gates, side pockets, and stressed liquidity.
• Confirm investment-adviser and commodity-pool obligations separately.
• Treat crypto venues, custody, wallets, and fiat banking as distinct controls.
• Keep share-class and side-letter terms in the accounting and approval process.
• Allocate SPC assets, liabilities, contracts, and expenses to the correct portfolio.
• Preserve provider transition, asset recovery, and wind-down plans.

How to use this guide

Treat this as an operating map, not a structure recommendation. The correct answer depends on the asset, investors, jurisdictions, offering method, tax position, and people performing regulated or fiduciary roles. Rules and provider services change. Confirm the live facts with qualified counsel, tax advisers, and the parties named in your actual documents.
