public class SwaptionSingleCurve
extends AbstractLIBORMonteCarloProduct

Implements the valuation of a swaption under a LIBORModelMonteCarloSimulationModel Important: If the LIBOR Market Model is a multi-curve model in the sense that the numeraire is not calculated from the forward curve, then this valuation does not result in the valuation of a collaterlized option on a collateralized swap. It will be a collaterlized option on a single curve (uncolateralized) swap. For a multi-curve valuation see Swaption.

Method Detail

getValue

public RandomVariable getValue(double evaluationTime,
                               LIBORModelMonteCarloSimulationModel model)
                        throws CalculationException

This method returns the value random variable of the product within the specified model, evaluated at a given evalutationTime. Note: For a lattice this is often the value conditional to evalutationTime, for a Monte-Carlo simulation this is the (sum of) value discounted to evaluation time. Cashflows prior evaluationTime are not considered.

Specified by:

getValue in interface TermStructureMonteCarloProduct

Specified by:

getValue in class AbstractLIBORMonteCarloProduct

Parameters:

evaluationTime - The time on which this products value should be observed.

model - The model used to price the product.

Returns:

The random variable representing the value of the product discounted to evaluation time

Throws:

CalculationException - Thrown if the valuation fails, specific cause may be available via the cause() method.

getValue

public double getValue(ForwardCurve forwardCurve,
                       double swaprateVolatility)

This method returns the value of the product using a Black-Scholes model for the swap rate The model is determined by a discount factor curve and a swap rate volatility.

Parameters:

forwardCurve - The forward curve on which to value the swap.

swaprateVolatility - The Black volatility.

Returns:

Value of this product

toString

public String toString()

Overrides:

toString in class AbstractMonteCarloProduct
