What it means
Investment managers often serve investors with very different tax positions and currencies, such as taxable individuals at home and tax-exempt institutions overseas. Running a separate portfolio for each group would duplicate work and fragment dealing.
The master-feeder structure solves this by separating the investors from the investments. Each investor subscribes to a feeder fund suited to their situation, typically an onshore feeder for domestic investors and an offshore feeder for international ones.
The feeder takes in the money, handles its own investor relations and fees, and invests everything into the master fund. The master fund then runs one single portfolio.
The arrangement looks similar to a fund of funds but works in the opposite direction. A fund of funds spreads money across many independent funds.
A feeder fund invests in exactly one fund, the master, so the structure concentrates management rather than diversifying it. The benefits are scale and simplicity.
One portfolio means one set of trades, one research effort and lower dealing costs per dollar managed, while each feeder can set its own fees, minimums and reporting to suit its market. The drawbacks are real too.
Offshore feeders can face withholding tax on dividends from the master's holdings, and investors with different tax treatments may want conflicting strategies from the same portfolio. For a business owner approached by such a fund, the practical point is that the entity taking your shares in an investment round may be a feeder.
The decisions ultimately come from the manager of the master fund it invests into.
In practice
Real-world examples.
Example
A hedge fund manager sets up one feeder for domestic taxpayers and an offshore feeder for foreign pension money. Both feed a single master fund trading one global equity strategy, cutting the dealing desk's work in half. Each feeder keeps its own investor reporting and fee terms.
Example
An offshore feeder receives dividends from the master fund's domestic shareholdings. Assuming an illustrative 30% withholding tax, a $1,000,000 dividend arrives as $700,000, reducing the return its investors see. The domestic feeder, with a different tax position, keeps more of the same dividend.
Example
Two feeders disagree on strategy: the tax-exempt feeder wants high-turnover trading while the taxable feeder prefers holding gains. The master fund's manager must run one compromise portfolio for both. The tension surfaces in the annual investor letters from both sides.
Formula
Calculation
Feeder ownership share = feeder assets / total master fund assets x 100. If two feeders hold $300 million and $200 million in a master fund of $500 million, they own 300 / 500 x 100 = 60% and 200 / 500 x 100 = 40%.
The master's net return flows through to each feeder in proportion to its share, before each feeder's own fees. If the master earns a 10% net return, that is $500 million x 10% = $50 million, so the first feeder receives $50 million x 60% = $30 million and the second receives $50 million x 40% = $20 million.Case study
Seen in the real world.
Fictional example: Castellan Capital, an imagined hedge fund manager, ran three separate portfolios for its domestic, European and Middle Eastern clients. Trading costs were high, and the three portfolios drifted apart even though the strategy was identical. The fictional firm merged them into one master fund with three feeders. Dealing costs fell by a third, performance across investor groups aligned, and the firm could report one track record.
The cost was complexity: the European feeder absorbed withholding tax its investors had not previously paid, which Castellan had to explain carefully in its first quarterly letter. In this invented story the firm also learned that each feeder still needed its own administration, audit and investor reporting, so the saving came mainly from dealing costs and portfolio management, not from running fewer legal entities. Every figure in the example is fictional.
Watch out
Common mistakes.
- Confusing a feeder fund with a fund of funds, when a feeder invests in only one master fund rather than spreading money across many.
- Ignoring withholding tax leakage at the master fund level, which can quietly reduce what offshore feeder investors actually receive.
- Assuming all feeder investors get identical outcomes, when different fee structures, expenses and tax treatments make their net returns differ in practice.
Questions
People also ask.
Why do hedge funds use this structure?
It lets one manager run a single portfolio for investors with different tax and regulatory situations. Each feeder serves its own investor group while the master fund trades once for everyone, cutting cost and complexity and giving the manager one clean track record to market.
Is a master-feeder fund the same as a fund of funds?
No. A fund of funds buys stakes in many independent funds to diversify. A feeder fund invests everything into one master fund, so the structure concentrates management in a single portfolio.
What is the main tax drawback?
Offshore feeders can face withholding tax on dividends paid by the master fund's holdings, at rates that vary by country and tax treaty. That tax reduces the return reaching the offshore investors and cannot always be reclaimed.
