rpv01OnSettle

public CurrencyAmount rpv01OnSettle(ResolvedCdsIndexTrade trade,
                                    CreditRatesProvider ratesProvider,
                                    PriceType priceType,
                                    ReferenceData refData)

Calculates the risky PV01 of the underlying product.

RPV01 is defined as minus of the present value sensitivity to coupon rate.

This is computed based on the settlement date rather than the valuation date.

Parameters:

trade - the trade

ratesProvider - the rates provider

priceType - the price type

refData - the reference date

Returns:

the RPV01

recovery01OnSettle

public CurrencyAmount recovery01OnSettle(ResolvedCdsIndexTrade trade,

                                         ReferenceData refData)

Calculates the recovery01 of the underlying product.

The recovery01 is defined as the present value sensitivity to the recovery rate. Since the ISDA standard model requires the recovery rate to be constant throughout the lifetime of the CDS, one currency amount is returned by this method.

This is computed based on the settlement date rather than the valuation date.

Parameters:

trade - the trade

ratesProvider - the rates provider

refData - the reference data

Returns:

the recovery01

jumpToDefault

public JumpToDefault jumpToDefault(ResolvedCdsIndexTrade trade,
                                   CreditRatesProvider ratesProvider,
                                   ReferenceData refData)

Calculates the jump-to-default of the underlying product.

The jump-to-default is the value of the product in case of immediate default of a constituent single name.

Under the homogeneous pool assumption, the jump-to-default values are the same for all of the undefaulted names, and zero for defaulted names. Thus the resulting object contains a single number.

Parameters:

trade - the trade

ratesProvider - the rates provider

refData - the reference data

Returns:

the recovery01

expectedLoss

public CurrencyAmount expectedLoss(ResolvedCdsIndexTrade trade,
                                   CreditRatesProvider ratesProvider)

Calculates the expected loss of the underlying product.

The expected loss is the (undiscounted) expected default settlement value paid by the protection seller. The resulting value is always positive.

Parameters:

trade - the trade

ratesProvider - the rates provider

Returns:

the recovery01
