Coupon

The coupon amount depends on the characteristics of the bond. It is expressed as a percentage of the face value and paid from the date of issue until maturity on predefined dates.

We call a coupon detachment when the coupon is paid. Between two coupon detachment dates, we speak of an accrued coupon to designate the pro rata interest. The price of a bond is therefore determined as the sum of its 'coupon foot' price - that is to say without taking into account the influence of the coupon - and the accrued coupon.

A zero-coupon bond does not detach a coupon by definition.
