Redemption date is the date on which a security (usually a fixed interest stock) is due to be repaid by the issuer at its full par value.
The year is included in the title of the security; the actual redemption date being that on which the last interest is due to be paid.
Alternatively, such a bond or share may carry two redemption dates and the stipulation that it will be repaid no earlier than the first date and no later than the second.
