Detailed Description

Bilateral (CVA and DVA) default adjusted vanilla swap pricing engine. Collateral is not considered. No wrong way risk is considered (rates and counterparty default are uncorrelated). Based on: Sorensen, E.H. and Bollier, T.F., Pricing swap default risk. Financial Analysts Journal, 1994, 50, 23–33 Also see sect. II-5 in: Risk Neutral Pricing of Counterparty Risk D. Brigo, M. Masetti, 2004 or in sections 3 and 4 of "A Formula for Interest Rate Swaps Valuation under Counterparty Risk in presence of Netting Agreements" D. Brigo and M. Masetti; May 4, 2005

to do: Compute fair rate through iteration instead of the current approximation . to do: write Issuer based constructors (event type) to do: Check consistency between option engine discount and the one given

Constructor & Destructor Documentation

CounterpartyAdjSwapEngine() [1/3]

CounterpartyAdjSwapEngine	(	const Handle< YieldTermStructure > &	discountCurve,
		const Handle< PricingEngine > &	swaptionEngine,
		const Handle< DefaultProbabilityTermStructure > &	ctptyDTS,
		Real	ctptyRecoveryRate,
		const Handle< DefaultProbabilityTermStructure > &	invstDTS = Handle<DefaultProbabilityTermStructure>(),
		Real	invstRecoveryRate = 0.999
	)

Creates the engine from an arbitrary swaption engine. If the investor default model is not given a default free one is assumed.

Parameters

discountCurve	Used in pricing.
swaptionEngine	Determines the volatility and thus the exposure model.
ctptyDTS	Counterparty default curve.
ctptyRecoveryRate	Counterparty recovey rate.
invstDTS	Investor (swap holder) default curve.
invstRecoveryRate	Investor recovery rate.

Definition at line 33 of file cvaswapengine.cpp.

CounterpartyAdjSwapEngine() [2/3]

CounterpartyAdjSwapEngine	(	const Handle< YieldTermStructure > &	discountCurve,
		Volatility	blackVol,
		const Handle< DefaultProbabilityTermStructure > &	ctptyDTS,
		Real	ctptyRecoveryRate,
		const Handle< DefaultProbabilityTermStructure > &	invstDTS = Handle<DefaultProbabilityTermStructure>(),
		Real	invstRecoveryRate = 0.999
	)

Creates an engine with a black volatility model for the exposure. If the investor default model is not given a default free one is assumed.

Parameters

discountCurve	Used in pricing.
blackVol	Black volatility used in the exposure model.
ctptyDTS	Counterparty default curve.
ctptyRecoveryRate	Counterparty recovey rate.
invstDTS	Investor (swap holder) default curve.
invstRecoveryRate	Investor recovery rate.

Definition at line 57 of file cvaswapengine.cpp.

CounterpartyAdjSwapEngine() [3/3]

CounterpartyAdjSwapEngine	(	const Handle< YieldTermStructure > &	discountCurve,
		const Handle< Quote > &	blackVol,
		const Handle< DefaultProbabilityTermStructure > &	ctptyDTS,
		Real	ctptyRecoveryRate,
		const Handle< DefaultProbabilityTermStructure > &	invstDTS = Handle<DefaultProbabilityTermStructure>(),
		Real	invstRecoveryRate = 0.999
	)

Creates an engine with a black volatility model for the exposure. The volatility is given as a quote. If the investor default model is not given a default free one is assumed.

Parameters

discountCurve	Used in pricing.
blackVol	Black volatility used in the exposure model.
ctptyDTS	Counterparty default curve.
ctptyRecoveryRate	Counterparty recovey rate.
invstDTS	Investor (swap holder) default curve.
invstRecoveryRate	Investor recovery rate.
