The major difference between a Unit Trust and a mutual fund is
that a mutual fund is actively managed, while a unit investment
trust is not managed at all. Capital gains, interest and dividend
payments from the trust are passed on to shareholders at regular
periods. If the trust is one that invests only in tax-free
securities, then the income from the trust is also tax-free.
A unit investment trust is generally considered a low-risk,
low-return investment.
Some investors prefer Unit Trusts to mutual funds because Unit
Trusts typically incur lower annual operating expenses (since they
are not buying and selling shares); however, Unit Trusts often have
sales charges and entrance/exit fees.
Mutual funds can be open ended or close ended. But unit trusts
are open ended instruments.
