CMS leg and pay leg are typically in the same currency. Thus the present value is expressed as a single currency amount in most cases.

Parameters:

cms - the CMS product

ratesProvider - the rates provider

swaptionVolatilities - the swaption volatilities

Returns:

the present value

explainPresentValue

public ExplainMap explainPresentValue(ResolvedCms cms,
                                      RatesProvider ratesProvider,

Explains the present value of the CMS product.

This returns explanatory information about the calculation.

Parameters:

cms - the CMS product

ratesProvider - the rates provider

swaptionVolatilities - the swaption volatilities

Returns:

the explain PV map

presentValueSensitivityRates
