Detailed Description

Capped and/or floored floating-rate coupon.

The payoff $ P $ of a capped floating-rate coupon is: [ P = N imes T imes min(a L + b, C). ] The payoff of a floored floating-rate coupon is: [ P = N imes T imes max(a L + b, F). ] The payoff of a collared floating-rate coupon is: [ P = N imes T imes min(max(a L + b, F), C). ]

where $ N $ is the notional, $ T $ is the accrual time, $ L $ is the floating rate, $ a $ is its gearing, $ b $ is the spread, and $ C $ and $ F $ the strikes.

They can be decomposed in the following manner. Decomposition of a capped floating rate coupon: [ R = min(a L + b, C) = (a L + b) + min(C - b - on"

void update () [virtual]

This method must be implemented in derived classes. An instance of Observer does not call this method directly: instead, it will be called by the observables the instance registered with when they need to notify any changes.

Reimplemented from FloatingRateCoupon.
