An endowment policy is a life insurance contract designed to pay a lump sum after a specific term (on its 'maturity') or on death. Typical maturities are ten, fifteen or twenty years up to a certain age limit. Some policies also pay out in the case of critical illness.
Policies are typically traditional with-profits or unit-linked (including those with unitised with-profits funds).
Endowments can be cashed in early (or surrendered) and the holder then receives the surrender value which is determined by the insurance company depending on how long the policy has been running and how much has been paid into it.
There is an amount guaranteed to be paid out called the sum assured and this can be increased on the basis of investment performance through the addition of periodic (for example annual) bonuses. Regular bonuses (sometimes referred to as reversionary bonuses) are guaranteed at maturity and a further non-guarantee bonus may be paid at the end known as a terminal bonus. During adverse investment conditions, the encashment value or surrender value may be reduced by a 'Market Value Reduction' or MVR (It is sometime referred to as a market value adjustment but this is a term in decline through pressure from the Financial Conduct Authority to use clearer terms). The idea of such a measure is to protect the investors who remain in the fund from others withdrawing funds with notional values that are, or risk being, in excess of the value of underlying assets at a time when stock markets are low. If an MVA applies an early surrender would be reduced according to the policies adopted by the funds managers at the time.
Unit-linked endowments are investments where the premium is invested in units of a unitised insurance fund. Units are encashed to cover the cost of the life assurance. Policyholders can often choose which funds their premiums are invested in and in what proportion. Unit prices are published on a regular basis and the encashment value of the policy is the current value of the units.
A full endowment is a with-profits endowment where the basic sum assured is equal to the death benefit at start of policy and, assuming growth, the final payout would be much higher than the sum assured.
A low cost endowment is a medley of: an endowment where an estimated future growth rate will meet a target amount and a decreasing life insurance element to ensure that the target amount will be paid out as a minimum if death occurs (or a critical illness is diagnosed if included).
The main thing of a low cost endowment has been for endowment mortgages to pay off interest only mortgage at maturity or earlier death in favour of full endowment with the required premium would be much higher.
