Structured notes: Range Floaters
(Range contingent accrual bonds)
Bonds that accrue interest only on days when range
conditions satisfied.
Example:
$10 million bond: 12% coupon, accrual range contingent;
range is ($.50, $.59) $/DM
semiannual coupon =
$10m x (.12) x (S (days within range)/365)
(this is a restart accrual; can be barrier terminal accrual)
14
Structured notes - Inverse floater
Example:
GNMA 10-year note; maturity 12/15/07
coupon paid semi-annually: 6/15 and 12/15
coupon = max(0.02, (0.18- 2xLibor)) x (180/360) x Face
coupon on $1 million note a function of Libor:
