Traded endowments are with-profits endowment policies that have been sold by the original owners before their maturity date.
These bonds pay interest every 6 months until they reach their 30-year maturity date.
When a bond is callable, it means the issuer can call back the bond and retire it prior to its scheduled maturity date.
The final payment on an annuity is referred to as the maturity date.
Fixed rate annuities are purchased for the long-term savings and allow you to lock in a certain rate at the time of purchase that you will continue to pay until the maturity date for the payout.
