A feeder fund is a pooled investment vehicle that collects capital from a defined group of investors and channels it into a master fund, which executes the actual investment strategy. The feeder does not make investment decisions. It exists as a structural layer to accommodate the specific tax, regulatory, or administrative needs of its investor base.
Why Feeder Funds Exist
The simplest answer: not all investors can sit in the same entity. A US pension fund, a Cayman-domiciled family office, and a European insurance company each face different tax treatment, regulatory constraints, and reporting obligations. Putting them all into one fund creates conflicts that no single structure can resolve cleanly.
The master-feeder model solves this by creating separate entry points. A domestic feeder (typically a Delaware LP or LLC) serves US taxable investors. An offshore feeder (often a Cayman Islands entity) serves non-US investors and US tax-exempt institutions like endowments and foundations that need to avoid unrelated business taxable income (UBTI). Both feeders invest into the same master fund, so the general partner runs one portfolio and one strategy regardless of how many feeders sit above it.
How the Structure Works
Each feeder fund is a separate legal entity with its own limited partnership agreement (or operating agreement, if structured as an LLC). Limited partners commit capital to their respective feeder. The feeder then subscribes for interests in the master fund in proportion to its committed capital.
Investment decisions, portfolio management, and exit execution all happen at the master fund level. Distributions flow back down through the feeders to the underlying LPs. From the investor’s perspective, the experience is largely the same as investing in a standalone fund, but the tax and reporting treatment is optimized for their specific situation.
Fund administration handles the accounting at both levels. The master fund maintains portfolio-level books, while each feeder maintains investor-level records, capital accounts, and K-1 or equivalent tax reporting for its LPs.
Feeder vs. Parallel Fund
The feeder model is sometimes confused with a parallel fund structure. The difference is important. In a master-feeder, the feeders invest into a single master entity that holds all the assets. In a parallel structure, each fund invests directly into portfolio companies on a side-by-side basis. Parallel funds are co-owners of the assets; feeders are investors in a common pool.
The choice between the two depends on strategy, investor requirements, and jurisdiction. Master-feeder is more common in hedge funds and liquid strategies. Parallel structures are more prevalent in private equity and venture capital, where investors may want direct ownership of underlying portfolio companies.
Practical Considerations
Standing up a master-feeder adds legal and administrative cost. You are forming and maintaining multiple entities, each requiring its own counsel review, audit, and tax filings. For smaller funds, this overhead can be hard to justify. Most managers do not implement a master-feeder until their fund formation involves a meaningfully diverse LP base that cannot be accommodated in a single vehicle.
The fund domicile of each feeder matters. Domestic feeders are usually formed in Delaware. Offshore feeders are commonly domiciled in the Cayman Islands, British Virgin Islands, or Luxembourg, depending on where the LP base is concentrated and what tax treaties apply.
Frequently Asked Questions
What is the difference between a feeder fund and a master fund?
A feeder fund pools capital from a specific type of investor and invests that capital into a master fund, which makes all the actual investment decisions. The master fund holds the portfolio. The feeder fund is essentially a pass-through entity that exists to accommodate the tax, regulatory, or reporting needs of its particular investor group.
Why would a fund manager use a feeder structure instead of one fund?
Different investor types have different tax and regulatory requirements. US taxable investors, US tax-exempt investors, and non-US investors often cannot invest efficiently through the same entity. Feeder funds solve this by creating separate entry points that all feed into one master portfolio, allowing the manager to run a single investment strategy while accommodating diverse LP needs.
Do feeder fund investors pay additional fees?
Feeder fund investors typically pay the same management fee and carried interest as if they invested directly in the master fund. However, the feeder entity itself incurs formation costs, audit fees, and administrative expenses that may be passed through to its investors. Managers should disclose these costs clearly in the fund's offering documents.
