Definition: Zero coupon bonds
All issues without coupon payment. Usually such bonds are issued at a discount and redeemed at par. They also include bonds issued at par and redeemed at a premium, for example bonds with the redemption value linked to an exchange rate or an index. Most of the discount or premium represents the equivalent of the interest accrued during the life of the bond.
