A life assurance policy that pays out a lump sum after a specific period of time or on death of the policyholder. They can be used as a vehicle for saving or as a way to repay a mortgage. It is important to remember that an endowment is a long-term commitment. A customer who surrenders their policy early may not get back the amount of money they have invested. Note: the definition does not apply to either an Endowment or a Pure Endowment.
