Investors subscribe for shares that are referable to a specific segregated portfolio, so their exposure is to that portfolio's assets alone. The portfolio can have its own investment manager, strategy, fee terms and dealing frequency, and it can be closed or wound up without affecting the others.
A segregated portfolio is sometimes called a sub-fund or a cell. It is not a separate legal person: contracts are entered by the SPC acting on behalf of the portfolio, which is why counterparties and custodians open accounts in the portfolio's name.
