Detailed Description

Credit default swap.

Note:

This instrument currently assumes that the issuer did not default until today's date.

Warning

if Settings::includeReferenceDateCashFlows() is set to true, payments occurring at the settlement date of the swap might be included in the NPV and therefore affect the fair-spread calculation. This might not be what you want.

Examples: CDS.cpp.

Constructor & Destructor Documentation

CreditDefaultSwap (Protection::Side side, Real notional, Rate spread, const Schedule & schedule, BusinessDayConvention paymentConvention, const DayCounter & dayCounter, bool settlesAccrual = true, bool paysAtDefaultTime = true, const Date & protectionStart = Date(), const boost::shared_ptr< Claim > & = boost::shared_ptr< Claim >())

CDS quoted as running-spread only.

Parameters:

side Whether the protection is bought or sold.
notional Notional value
spread Running spread in fractional units.
schedule Coupon schedule.
paymentConvention Business-day convention for payment-date adjustment.
dayCounter Day-count convention for accrual.
settlesAccrual Whether or not the accrued coupon is due in the event of a default.
paysAtDefaultTime If set to true, any payments triggered by a default event are due at default time. If set to false, they are due at the end of the accrual period.
protectionStart The first date where a default event will trigger the contract.

CDS quoted as upfront and running spread.

Parameters:

side Whether the protection is bought or sold.
notional Notional value
upfront Upfront in fractional units.
spread Running spread in fractional units.
schedule Coupon schedule.
paymentConvention Business-day convention for payment-date adjustment.
dayCounter Day-count convention for accrual.
settlesAccrual Whether or not the accrued coupon is due in the event of a default.
paysAtDefaultTime If set to true, any payments triggered by a default event are due at default time. If set to false, they are due at the end of the accrual period.
protectionStart The first date where a default event will trigger the contract.
upfrontDate Settlement date for the upfront payment.

Member Function Documentation

void setupArguments (PricingEngine::arguments *) const [virtual]

When a derived argument structure is defined for an instrument, this method should be overridden to fill it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

void fetchResults (const PricingEngine::results * r) const [virtual]

When a derived result structure is defined for an instrument, this method should be overridden to read from it. This is mandatory in case a pricing engine is used.

Reimplemented from Instrument.

Rate fairUpfront () const

Returns the upfront spread that, given the running spread and the quoted recovery rate, will make the instrument have an NPV of 0.

Rate fairSpread () const

Returns the running spread that, given the quoted recovery rate, will make the running-only CDS have an NPV of 0.

Note:

This calculation does not take any upfront into account, even if one was given.

Examples: CDS.cpp.

Real couponLegBPS () const

Returns the variation of the fixed-leg value given a one-basis-point change in the running spread.

Rate impliedHazardRate (Real targetNPV, const Handle< YieldTermStructure > & discountCurve, const DayCounter & dayCounter, Real recoveryRate = 0.4, Real accuracy = 1.0e-6) const

Implied hazard rate calculation.

Note:

This method performs the calculation with the instrument characteristics. It will coincide with the ISDA calculation if your object has the standard characteristics. Notably:

·
The calendar should have no bank holidays, just weekends.
·
The yield curve should be LIBOR piecewise constant in fwd rates, with a discount factor of 1 on the calculation date, which coincides with the trade date.
·
Convention should be Following for yield curve and contract cashflows.
·
The CDS should pay accrued and mature on standard IMM dates, settle on trade date +1 and upfront settle on trade date +3.

Rate conventionalSpread (Real conventionalRecovery, const Handle< YieldTermStructure > & discountCurve, const DayCounter & dayCounter) const

Conventional/standard upfront-to-spread conversion. Under a standard ISDA model and a set of standardised instrument characteristics, it is the running only quoted spread that will make a CDS contract have an NPV of 0 when quoted for that running only spread. Refer to: 'ISDA Standard CDS converter specification.' May 2009.

The conventional recovery rate to apply in the calculation is as specified by ISDA, not necessarily equal to the market-quoted one. It is typically 0.4 for SeniorSec and 0.2 for subordinate.

Note:

The conversion employs a flat hazard rate. As a result, you will not recover the market quotes.

void setupExpired () const [protected], [virtual]

This method must leave the instrument in a consistent state when the expiration condition is met.
