A master-feeder structure places all investment activity in a single "master" fund. Investors access the master fund through one or more "feeder" entities, each designed for a specific investor type: U.S. taxable, U.S. tax-exempt, or non-U.S. This structure is standard for hedge funds managing over $500 million and increasingly common for large private equity and venture capital funds.
How Master-Feeder Works
The master fund holds all portfolio investments, executes all trades, and maintains all position-level records. It is the only entity that interacts with brokers, custodians, and portfolio companies.
Each feeder fund is a separate legal entity that accepts subscriptions from a specific investor class. The feeder's sole investment is its LP interest in the master fund. Capital flows upward: investors commit to a feeder, the feeder commits to the master, and the master deploys capital.
Distributions reverse the flow. The master distributes to feeders based on their pro rata interest, and each feeder distributes to its own investors according to its partnership agreement.
Each feeder has its own subscription documents, its own partnership agreement, and its own investor onboarding process. An investor in the offshore feeder never signs the domestic feeder's documents, and vice versa.
Typical Structure
The standard three-entity master-feeder looks like this:
- Domestic feeder (Delaware LP or LLC) for U.S. taxable investors. Taxed as a partnership, so investors receive K-1s reflecting their share of fund income and losses.
- Offshore feeder (Cayman Islands exempted limited partnership or company) for non-U.S. investors and U.S. tax-exempt investors. Structured as a corporation for U.S. tax purposes, which blocks UBTI and ECI from flowing through to its investors.
- Master fund (Cayman Islands LP or Delaware LP) holds all investments. The two feeders are its only limited partners.
Some structures add a fourth entity: a blocker corporation between the offshore feeder and the master fund, specifically to handle ERISA plan asset issues or additional tax blocking.
Benefits
Single portfolio management. You manage one set of investments in one entity. There is no need to coordinate allocations across multiple vehicles or worry about pari passu compliance. Every dollar in the master fund is deployed identically regardless of which feeder it came from.
Automatic proportional allocation. Because feeders are LPs in the master, each feeder's share of gains, losses, and distributions is proportional to its capital account. No manual allocation calculations are required at the investment level.
Consolidated trading and custody. One brokerage relationship, one set of counterparty agreements, one custody arrangement. This reduces operational complexity and often results in better execution and lower trading costs.
Single audit at the master level. The master fund's financial statements cover the entire portfolio. Feeder audits are simpler because their only asset is the LP interest in the master.
Costs and Complexity
A master-feeder structure requires forming and maintaining at least three legal entities. Each entity needs its own formation documents, registered agent, and regulatory filings.
Formation costs typically run $150,000 to $250,000 in legal fees for the full structure. Annual operating costs include:
- Master fund audit: $40,000 to $80,000
- Domestic feeder audit: $15,000 to $30,000
- Offshore feeder audit: $15,000 to $30,000
- Cayman regulatory fees (CIMA): $5,000 to $10,000 per Cayman entity
- Registered agent fees: $2,000 to $5,000 per entity
- Tax preparation across entities: $30,000 to $60,000
Cost Threshold
At $100,000 to $200,000 in annual structure costs, a master-feeder generally requires at least $200 million in AUM to be economically justified. Below that level, the structure's cost drags on returns more than simpler alternatives.
Master-Feeder vs. Parallel
Both structures solve the same problem: accepting capital from different investor types. The choice comes down to portfolio management complexity and cost.
Choose master-feeder when you have a high volume of trades or positions (hedge funds, liquid credit), you want to avoid pari passu allocation tracking entirely, or your fund will scale above $200 million.
Choose parallel when you make a small number of investments per year (PE, VC), your investors need complete tax separation between vehicles, or your fund is between $50 million and $200 million where the simpler structure saves meaningfully on costs.
At $50 million to $100 million, a parallel structure saves $50,000 to $80,000 per year compared to a full master-feeder. At $500 million and above, the operational efficiency of master-feeder more than offsets its higher cost.
Common Mistakes
Building a master-feeder for a small fund. A $50 million fund using a master-feeder will spend 20 to 40 basis points annually just on structure costs. A single Delaware LP with side letters for specific investors accomplishes the same goal at a fraction of the cost.
Mismatched redemption terms. If your domestic feeder allows quarterly redemptions with 45-day notice but your offshore feeder allows monthly redemptions with 30-day notice, you create liquidity mismatches at the master level. Redemption terms should be coordinated across all feeders.
Tax planning gaps. The offshore feeder's corporate structure blocks UBTI, but it also means non-U.S. investors cannot claim treaty benefits on U.S.-source income flowing through the master. Your tax advisor should model the full tax impact for each investor type before you finalize the structure.
