The master-feeder fund structure allows fund managers to benefit from the efficiencies of larger pools of finances while providing the flexibility of designing smaller funds, which are tailor-made for different market situations.
One or more investment vehicles pool their finances within another vehicle – i.e. there are several smaller feeder funds and one master to which they contribute. This master fund is then responsible for performing all the investments of the assets transferred to it from the feeders.
Sometimes, especially when the feeders are hedge funds, this is a way of complying with the distinct legal systems of separate jurisdictions.
